(10) Referring to FIGS. 1-5, and initially with regard to FIG. 1, a grow light fan 100 is illustrated in accordance with an exemplary first embodiment of the present invention. The grow light fan 100 generally includes a motorized housing assembly 110, including a bell housing 112 and a motor 114 mounted within the bell housing 110, and a fan blade assembly 116 including a central hub 118 having a plurality of fan blade units 120 extending outwardly or radially from the central hub 118. Each fan blade unit 120 includes a paddle shaped fan blade 122 connected to the central hub 118 by a support bar 124. For example, the fan blade assembly 116 may be the entire rotating structure. The fan blade unit 120 may include one fan blade, and one or more structures (e.g. central hub 118 and/or the support bars and/or the connecting bars) to rotatably attach the fan blade to the housing or the motor support bracket 134. The fan blade 122 may be an individual fan blade (e.g. a majorly planar structure). In some embodiments, the fan blades may be rods or the fan blades may have any appropriate width, thickness, or length. The fan blades may have a same width all along a length of the fan blades. It is to be understood that the definition of the term fan blade as used herein is not limited to being the definition of a commonly known fan blade, and may instead be a rod or a stick or any long object that can be rotatably attached radially to the motorized housing assembly or fixedly attached to a rotating structure of the motorized housing assembly, or any long planar object that may force or circulate air when moved in a generally normal (perpendicular) direction with respect to a planar surface of the planar object. The grow light fan 100 may include any number of fan blades, such as between 1-12 fan blades. The fan blades may be directly attached to the central hub 118 or indirectly attached to the central hub 118 via the support bars 124. The fan blades may be directly or indirectly attached to the rotating lower unit 128 of the motor 114. The fan blades may be fixedly attached to any rotating element of the motor. Connecting bars 126 extend from a rotating lower unit 128 of the motor 114 and are affixed to the support bars 124 such that rotation of the rotating lower unit 128 rotates, or causes to rotate, the entire fan blade assembly 116 about or relative to the motorized housing assembly 110. The fan blades may be attached to any structure that is rotated by the motorized housing assembly or motor. For example, the motor may cause the lower unit 128 or the central hub 118 to rotate, subsequently causing the one or more fan blades that are attached to the lower unit 128 or the central hub 118 to rotate, or more generally, causing the fan blade assembly 116 to rotate. For example, the blades 122 may rotate about an axis (shown as rotation axis R in FIG. 1) of the rotating or rotatable lower unit 128, and/or the rotatable central hub 118, the axis being vertical and perpendicular with respect to a ceiling (i.e. support structure) or flat object on which the housing 112 is attached, or in some embodiments, the axis being perpendicular with respect to a rotational plane (or bottom structural plane) of the lower unit 128 or the central hub 118. For example, the lower unit 128 or the central hub 118 may be cylindrical, or have a circular or circular planar rotating portion that rotates in a plane in a circular manner, and a longitudinal direction of the rotation axis R of the blades may be generally perpendicular to the plane of rotation of the central hub 118 or the lower unit 128. If imaginarily extended, the rotation axis R may vertically pass through a center of the motorized housing assembly, the lower unit 128, or the central hub 118 symmetrically and/or centrally. For example, the various rotating components that rotate about the rotation axis R may be radially symmetrical to avoid wobbling of the grow light fan 100 during operation of the grow light fan 100, and/or the rotation axis R may pass through a center of mass of the motorized housing assembly 110 upward as shown in FIG. 1. As another example, the rotation axis of the fan blades 122 may be perpendicular to a plane in which the fan blades 120 rotate in, or pass through during rotation. It is to be understood that the fan blade units 120 and the fan blades 122 may be invariably referred to herein. The rotation axis may be located at or may extend through a central structure (e.g. central hub 118, the lower unit 128, and/or housing 112) where the fan blades are attached, directly or indirectly. The fan blade units 120 may be or may extend flat and parallel with respect to the plane in which the fan blades rotate. In other words, the fan blade units 120 may be flat and may extend perpendicular with respect to the rotational axis R, where a normal direction of a face of the fan blade units 120 are parallel with respect to the rotational axis R. Alternatively, the fan blade units may be or may extend non-perpendicular with respect to the rotational axis R. The fan blades may be planar, and each fan blade may have a major planar surface or a face, where the planar surface may have a normal (perpendicular) direction that is either parallel with the rotation axis R or slightly or significantly tilted away and non-parallel with respect to the rotation axis R. The fan blades may be in a same plane of rotation of the rotating central hub 118 and/or rotating lower unit 128. The fan blades may be angled relative to a plane of rotation of the fan blades.

(11) It is to be understood that the central hub 118 may be one rotatable structure on which all fan blades are indirectly or directly attached, or may be a plurality of rotatable structures to which one or more fan blades are each attached respectively to each rotatable structure of the plurality of rotatable structures. For example, each rotatable structure of the plurality of rotatable structures may include rings 162 and 164, or an equivalent structure providing the same functionality. For example, each rotatable structure of the plurality of rotatable structures may each include pickups 188 and 190 as shown in FIG. 6. As an example, FIG. 2 shows the central hub 118 including a plurality of rotatable structures that slide along the channels of the support cylinder 134.

(12) It is to be understood that the bell housing may be fixedly attached to a ceiling or other fixed structure (i.e. support structure, a rack, or a frame), at a top area of the bell housing. The bell housing itself may be considered a support structure for the rest of the grow light fan elements. Further, it is to be understood that various structures remain fixed relative to the bell housing or the ceiling or the fixed structure, and various other structures rotate or move relative to the bell housing or the ceiling or the fixed structure. Any of the structures that remain fixed relative to the rotating structures may be referred to as a support structure, and any rotating structure may be referred to as a rotating structure. For example, the motor support bracket 134 remains fixed relative to the bell housing 112. The fan blades 122, the connecting bar 126, the support bar 124, the central hub 118, and the rotating lower unit 128 may rotate about rotational axis R. The motor 114 itself may rotate, or may be configured to cause the rotating parts to rotate. The motor support bracket 134 may be considered a support structure.

(13) Rotating the fan blades causes a stream of air to move across the fan blade units 120, and/or causes air to be projected generally downward and generally or exactly parallelly with respect to a longitudinal direction of rotation axis R of the rotating blades 120. For example, air may be projected downward away from the housing 112, or alternatively upward toward the housing 112 according to the configuration, tilt and angle of the fan blades with respect to the rotation axis R. The fan blades 120 rotating causes air to circulate in a room, a vicinity, or general area where the grow light fan 100 is disposed. For example, the fan blades may be configured to push air down or pull air up due to their rotation. It is to be understood that the fan blades may rotate in a clockwise or counterclockwise direction. The fan blades are configured to move air such that localized heat, or hot spots, are eliminated or dissipate as further described below.

(14) In order to uniformly illuminate plants and maximize surface area of the plants that is exposed to illumination, the fan blade units 120 additionally include a plurality of grow lights 130 provided, attached, or fixed to or within and/or on an underside 132 of each of the fan blades 122 of the fan blade units 120. The grow lights 130 are preferably, individual Light Emitting Diodes or LED's extending or projecting laterally, downwardly, or in a downward normal direction with respect to a major planar surface of each fan blade, or generally projecting from the undersides 132 of the fan blades 122. For example, the LED's may be configured, placed, or aimed to illuminate target plants disposed downward from a rotating plane of the rotating fan blades, or generally or directly below the grow light fan 100, or in a downward longitudinal direction of the rotation axis R described above. The grow lights 130 may be any appropriate light configured to stimulate plant growth, and may be configured to emit an electromagnetic spectrum appropriate for photosynthesis, and may be housed flush within the fan blades or otherwise may be slightly projecting perpendicularly from major planar surfaces of the fan blades. The grow lights may be each surrounded by a space, hole or dip such that more surface area of each light is exposed to moving or cool air. The grow lights may extend through a thickness of the fan blades, the thickness having a vertical and normal (perpendicular) dimension with respect to a major planar surface of the fan blades. The grow lights 130 may extend through the thickness of the fan blades either completely or partially. In some embodiments, the grow lights 130 are simply attached to a continuous major planar surface of the fan blades. By extending or projecting laterally from the undersides 132 of the fan blades 122, the grow lights 130 (LED's) are cooled by air passing over them as the fan blade assembly 116 rotates about the motorized housing assembly 110 (e.g. about rotation axis R). A motor support bracket or cylinder 134 is attached to the bell housing 112 and supports the motor 114 for providing rotation of the rotating elements relative to the bell housing 112. The motor support cylinder 134 additionally provides an electrical conduit between the motorized housing assembly 110 and the grow lights 130 provided on the fan blades 122 as described in more detail herein. For example, the motor support cylinder 134 maintains electrical contact between the grow lights 130 and a power source continuously during rotation of the fan blades 122. Rotating the fan blades 122 causes air to circulate in a room or area in which the grow light fan 100 is disposed such that localized hot spots of heat may be eliminated. For example, heat localized near the grow lights 130, caused by the grow lights 130, may be dissipated due to the air circulation or air passing over the fan blades 122 caused by the rotating fan blades 122. Further, heat localized near plants or other objects in an area may be forced away, dissipated, or eliminated by aiming or targeting the air projected by the fan blades rotating toward a target plant or other object. General air circulation caused by the rotating fan blades may dissipate or eliminate localized heat spots in a general plant growing area. As such, the circulating air removes the requirement of heat sinks for the grow lights 130.

(15) The grow lights 130 may be placed on the fan blades 122 in a specific arrangement to provide a total of 1500 Watts per grow light fan 100. In some embodiments, each fan blade 122 includes a plurality of grow lights 130 to provide a 1500 Watt arrangement per fan blade. As a non-limiting example, each fan blade 122, or each grow light fan 100, may include 230 LEDs that are configured to emit light having exactly or approximately a wavelength of 630 nanometers (nm), 24 LEDs that are configured to emit light having exactly or approximately a wavelength of 460 nanometers, 14 LEDs that are configured to emit light having exactly or approximately a wavelength of 610 nanometers, 4 LEDs that are configured to emit light having exactly or approximately a wavelength of 410 nanometers, 4 LEDs that are configured to emit light having exactly or approximately a wavelength of 850 nanometers, 22 LEDs that are configured to emit light having exactly or approximately a color temperature of 14000K, and/or 2 LEDs that are configured to emit light having exactly or approximately a wavelength of 520 nanometers. Such wavelength values may vary up to +?20 nm and the color temperature values may vary up to +?1000 k.

(16) Ranges of wavelengths may be attributed to colors. For example, 440-460 nm may be royal blue, 460-490 nm may be blue, 490-520 nm may be cyan, 520-550 nm may be green, 585-597 nm may be amber, 613-620 nm may be orange, and 620-645 nm may be red. Chlorophyll performs photosynthesis by absorbing light. Chlorophyll has two main absorption peaks: one peak between 650-670 nm (red), and one peak between 430-450 nm (blue). As such, the grow lights 130 may be configured to provide light within the red absorption peak and/or blue absorption peak to maximize plant growth and health. Generally, wavelengths between 400 nm (blue) and 700 nm (red) are considered photosynthetically active radiation. As such a majority of grow lights 130 may be configured to emit light in the red or blue spectrum. As a non-limiting example, a ratio of red-spectrum lights or light to blue-spectrum lights or light may be between 4-to-1 and 20-to-1. It has been found that a 14-to-1 ratio of red LEDs to blue LEDs has been effective. In some embodiments the grow lights 130 may be configured to provide ultraviolet or infrared light.

(17) Rotating the fan blades 122 while the grow lights 130 are illuminated illuminates a target plant arrangement below the grow light fan 100 with an even spectrum of light, similar to that of the sun. Since the fan blades and subsequently the grow lights rotate during illumination of the plants, at every subsequent moment, target plants receive an even, mixed, and a variety of light from the electromagnetic spectrum. For example, at a first instant a particular plant may receive a first spectrum exposure governed by a first position of the grow light fan 100. At a second instant, the particular plant may receive second a spectrum exposure governed by a second position of the grow light fan 100, the second spectrum exposure being different from the first spectrum exposure since the grow light fan 100 has moved from the first position to the second position.

(18) Referring for the moment to FIG. 2, the individual fan blades 122 are connected to the central hub 118 by the support bars 124. Specifically, a first end 136 of the support bars 124 are affixed to the central hub 118 and a second end 138 of the support bars 124 are affixed to an upper side 140 of the fan blades 122. The fan blades 122 are provided to circulate air within a grow room and include a narrower inner blade end 142 and a wider outer blade end 144. However, the width of the fan blade 122 may be equivalent at the inner blade end 142 and the outer blade end 144, and any region in between the ends, without departing from scope of this disclosure. The second end 138 of the support bars are connected to the narrower inner blade end 142 of the fan blades 122. As shown, an outer end 146 of the connecting bars 126 is attached to a central portion of the support bars 124 for the motor 114 to rotate the fan blade assembly 116 relative to the bell housing 112 (see also FIG. 1). For example, the motor 114 may rotate the lower unit 128. The connecting bars 126 may be fixedly attached to the rotatable lower unit 128 and to either the fan blades or to the support bars 124. As such causing the lower unit 128 to rotate causes the connecting bars 126, the support bars 124, and the fan blades 122 to rotate. Each support bar 124 may be connected to one fan blade 122, and/or each connecting bar 126 may be connected to one fan blade 122. Further, each connecting bar 126 may be connected to one support bar 124 as shown in FIG. 1. The support bars 124 may be fixedly connected directly to the rotating lower unit 128 or any rotating element. It is to be understood that the each fan blade may be connected via only one bar to a rotating element or structure of the motor or motorized housing assembly. For example, a connecting bar may connect a fan blade 122 to the lower rotating unit 128 or the central hub 118.

(19) With reference to FIGS. 3 and 4, in order to control the speed and direction of rotation of the motor 114 and, more particularly, to control the illumination provided by the grow lights 130, the grow light fan 100 includes a controller 150 mounted within the motorized housing assembly 110 (on-board), or mounted off-board (e.g. on a wall, or a wired remote device or controller). The controller 150 is configured to receive signals or instructions from a wired or remote device or controller, where receiving the instructions causes the controller 150 to affect the illumination provided by the grow lights (e.g. color, wavelength, or intensity) and to affect the rotational speed and direction of the motor and subsequently the fan blades, according to the nature of the received instructions. The controller may be operable to provide the functions described herein via a pull chain or switch or dial as found in typical ceiling fans and portable fans. For example such a pull chain may be pulled to switch between parameters or settings of the controller. A dial may be included to dial between the various different parameters or settings.

(20) It is to be understood that each grow light 130 or each set of grow lights 130 or each plurality of grow lights 130 on each fan blade 122 may be operatively connected to a respective controller. As such, a plurality of controllers may be included in the grow light fan 100. For example, a controller may be disposed on each fan blade 122, or each fan blade unit 120 for controlling one or more grow lights. In embodiments where a controller is disposed on a fan blade unit 120 or a fan blade 122, the controller receives power through the electrical connection provided by the mating of the motor support bracket 134 and the central hub 118.

(21) As shown in the figures, the controller 150 is mounted on a stationary top surface 152 of the motor 114. Alternatively, the controller 150 may be mounted to the bell housing 112 of the motorized housing assembly 110, or any suitable surface of the grow light fan 100. For example, the controller 150 may be mounted to the rotating lower unit 128, the connecting bars 126, the support bars 124, motor support cylinder 134, the support bracket 134, or the central hub 118. The controller 150 is provided and configured to allow the user or grower to remotely adjust the intensity, color and even wavelengths of the grow lights 130 via user input. For example, the controller 150 may be configured to cause the intensity, color or wavelength of the grow lights 130 to change in response to a user input indicating an outcome desired by a user (e.g. increase or decrease wavelength, color, intensity, or selectively switch LED(s) on or off). The controller 150 may be operative to selectively switch on or off one or more (e.g. a pattern of) the grow lights 130. For example, the controller may be configured to switch on or off certain LED's of a certain color or intensity. The controller 150 may be settable to a specific preset in response to a user input that indicates the specific preset. An example preset may be fast, medium or slow rotation speed of the rotating fan blades, or low, medium, or high intensity for the LED's. Further, various color settings may be programmed into or via the controller 150, such as a mono-color setting or any setting that may maximize growth and health of an illuminated plant. Further, the controller 150 may allow the individual LED's of the grow lights 130 to be adjusted independently of each other to customize a grow light illumination or pattern emitted by the grow lights 130. The controller 150 generally includes a control or circuit board 154 and an antenna or receiver 156 for receiving control instruction signals from a wireless or wired remote control (not shown) for causing operative changes of the grow light fan 100. The signals may come in the form of electrical, digital, Radio Frequency or RF signals, Wi-Fi type signals, Bluetooth signals, etc. and may be chosen as to not interfere or be interfered with by other signals being transmitted in the vicinity of the grow light fan light. The signals may be transmitted to the controller 150 by a hand held device or computer. As such, a remote control device may receive a user input to send instructions to the controller 150 for changing the operation parameters or settings of the grow light fan 100, the settings or parameters being one or more of rotation speed, rotation direction, light intensity, wavelength, color, illumination pattern, illumination time, or shutoff time. The remote controller may switch on or off the grow lights 130 or the motor 114. The instructions may be receivable by the controller 150 to define a rotation speed or angular velocity of the fan blades, or to define illumination settings or parameters for the LED's. For example, the illumination settings may include an illumination wavelength, color, intensity, or pattern of LED's (e.g. a color, intensity or illumination pattern). As such the controller 150 is operatively connected to the motor 114 and/or the grow lights 130 to control the motor 114 and/or the grow lights 130.

(22) The remote control device may be a handheld computer such as a smartphone, and the smartphone may be equipped with a software application that provides a user of the handheld device with an interface to control the controller 150 wirelessly or wiredly via user inputs such as taps on a touch-screen display or clicks via a cursor. Further, a camera may be set up to record and provide to the user live footage of a grow operation that is illuminated by the grow light fan 100. The footage may be provided to the user device via a data network connection such as the internet, for example.

(23) In some embodiments one or more green LED lights may be located either on a rotating or non-rotating (e.g. fixed) structure of the grow light fan 100 to provide a user with visibility in low-light conditions. Plants do not see green light and as such placing green lights on the grow light fan 100 to illuminate a growing area in low-light conditions will not interfere with growth of the plants. For example, such green light LED's may be disposed or mounted at the bottom of the lower unit 128, or on any structure of the grow light fan 100.

(24) Referring now to FIG. 5, in order to transmit both power to the grow lights 130 and signals received from the controller 150 to the grow lights 130 before or while the grow lights 130 are rotating with the fan blade units 120 about the motorized housing assembly 110, the motor support cylinder 134 includes a pair of horizontally oriented, upper and lower circumferential channels 158 and 160, respectively (See also, FIG. 4). The upper and lower channels 158 and 160 function as rotational electrical connectors or contacts for engagement with corresponding inwardly directed upper and lower rings 162 and 164 extending from the central hub 118 of the fan blade assembly 116. For example, the motor support cylinder 134 maintains electrical contact between the grow lights 130 and a power source continuously during rotation of the fan blades 120. As such, the upper and lower channels 158, and central hub are mated or coupled such that the grow lights 130 are powered for illumination continuously while the fan blades rotate. For example, the grow lights 130 may be powered continuously through a full 360 degree rotation, or full range of motion, of a fan blade. Additionally, the positions of the upper ring 162 and the lower ring 164 of the central hub 118 within the upper and lower channels 158 and 160, respectively, of the motor support cylinder 134 functions to rotatably support the fan blade assembly 116 on the motorized housing assembly 110. Cables 166 and 168 extend from the controller 150 to contact pads (not shown) located within the upper and lower channels 158 and 160 to transmit power and control instructions or settings to the grow lights 130 through the central hub 118. The controller 150 controls the LED's (e.g. power) through the rotatable connection offered by the mating of the channels 158 and 160 and lower rings 162 and 164. A power cord 170 runs from an external source of power to the controller 150 to power the grow light fan 100. A grounded connection may be included on the motor 114 or the bell housing 112. The controller 150 is also operatively connected to the motor 114 for controlling a rotation speed and direction of the motor. The controller 150 may be operatively connected wirelessly or wiredly to a remote control device such as a smart phone, a laptop or a computer terminal.

(25) As shown, a flange 172 of the motor support cylinder 134 supports the motor support cylinder 134, the motor 114 and the controller 150 from or on the bell housing 112 and outwardly extending upper and lower channels 174 and 176 of the motor support cylinder 134 rotatably support the fan blade assembly 116, specifically the central hub 118 of the fan blade assembly 116, on the motor support cylinder 134.

(26) With reference to FIGS. 5 and 6, the electrical system and use of the grow light fan 100 will now be described. The central component of the electrical system is the controller 150 which may receive input from an operator (user) via a transmitter or remote controller (not shown) and converts or processes that input to control the motor 114 and the grow lights 130. For example, the controller 150 may turn the grow lights 130 on or off. The controller 150 receives power from an external source through power cord 170 and is in electrical communication with the motor 150 through motor power line 178. Thus, the controller 150 can control the direction and speed of the fan blade assembly 116 driven by the motor 114 as described hereinabove.

(27) The controller 150 also controls each of the individual grow light 130 LED's on the underside 132 of the individual paddle shaped fan blades 122. It should be noted that the controller 150 can adjust the brightness or wavelength of all of the grow lights 130 collectively on all the fan blades 122 such that all the grow lights 130 are adjusted together, or separately for each fan blade 122 such that all the grow lights 130 on the same fan blade 122 are adjusted similarly, or individually on each individual fan blade 122 such that each grow light 130 on a single fan blade 122 is adjusted separately. Further, in some instances, it is desirable to adjust the intensity of the grow lights 130 radially along the fan blades 122 to project an even distribution of light. For example, the brightness or intensity of grow lights 130a near the narrower inner blade end 142 of the fan blade 122 may be adjusted lower than the grow lights 130c near the wider outer blade end 144 to compensate for the further radial spacing or light density of the grow lights 130c across the fan blade assembly 116. Grow lights 130b, located between the narrower inner blade end 142 and the wider outer blade end 144 may be adjusted in intensity between that of the grow lights 130a and 130c. As such, a cross sectional plane under the grow light fan 100 taken across a path of the illumination light will have an even spectrum of light, the cross sectional plane taken perpendicularly to the rotational axis R.

(28) In order to control the grow lights 130, the controller 150 transmits the appropriate power through cables 166 and 168 to the upper and lower channels 158 and 160 in the motor support cylinder 134. The cables 166 and 168 terminate in and connect to upper and lower contact pads 180 and 182 located within the upper and lower channels 158 and 160, respectively, of the motor support cylinder 134. A pair of blade cables 184 and 186 extend through the central hub 118 of the fan blade assembly 116 to the individual grow lights 130 on the fan blades 122. Upper and lower pickups 188 and 190 are positioned on the upper and lower rings 162 and 164, respectively, of the central hub 118 and are in electrical communication with the upper and lower contact pads 180 and 182 on the motor support cylinder 134. This allows the electrical signals to be transmitted between the motor support cylinder 134 and the central hub 118 while the central hub 118 and the motor support cylinder 134 rotate relative to each other. For example, electrical contact or communication channels remains between the blade cables 184 and 186, and the cables 166 and 168 while the upper and lower rings 162 and 164 rotatably slide along channels 158 and 160 respectively. As such, the LED's remain powered according to the settings, parameters, or presets the controller 150 is programmed to hold via the above described remote control.

(29) It should be noted that, by providing the individual grow lights 130 directly laterally protruding from the underside 132 of the fan blades 122, the grow lights 130 are in the direct air flow across the fan blades 122 such that the grow lights are continually cooled by the air currents passing over the fan blades 122 as they rotate. In this manner, extra fans, auxiliary ventilation systems not required to maintain the grow lights 130 at acceptable temperatures to prevent overheating. On the other hand, each fan blade may have faces that are parallel with respect to other faces of other fan blades and/or parallel with a rotational plane of the fan blades. The grow lights 130 may be arranged in a particular way to provide maximal airflow to each grow light of the grow lights 130. For example, the grow lights 130 may be arranged in a pattern that evenly provides airflow to each grow light 130 for cooling the grow lights or removing hot spots around each grow light. For example, the grow lights 130 may be disposed in a triangular pattern found in bowling pin starting arrangements, where each grow light 130 is slightly offset from a frontal grow light 130. As such, the grow lights may be disposed or fixed as a series of parallel rows, where each row is slightly offset from an adjacent row so that air flows evenly through the grow lights.

(30) Thus, the grow light fan 100 provides a novel and useful device and method of providing a remotely user variable growing light to plants while maintaining the individual grow lights 130 at acceptable temperatures to avoid overheating of the grow lights 130. Further, the grow light fan 100 provides a uniform spectrum of light intensity to target plants, and is configured to allow a user to selectively adjust light intensity of the lights and environmental temperature in a grow room environment.
