DETAILED DESCRIPTION WITH REFERENCE TO DRAWINGS

(12) FIG. 2 shows a round orientation specific luminaire 5 with two coupled crescent formed PCB's retaining a plurality of LED lamps mounted above an elongated space aisle 40. The elongated space 40 includes at least a horizontal surface/floor 1 (sometimes referred to as an aisle horizontal surface), and vertical surfaces 2 (sometimes referred to as a face or a rack). FIG. 2 is shown from the perspective of a ceiling above the luminaire 5 and to which the luminaire 5 is supported directly, or indirectly. The elongated space 40 is typically defined by an aisle floor 1 with vertical surfaces 2 adjacent to the long side of the aisle's floor surface 1. The orientation specific luminaire 5 is configured to be mounted above an aisle 1 of an elongated space 40 with specific orientation lensed optics 24. The specific orientation lensed optics is disposed over a plurality of LED lamps 3 coupled to at least one PCB 15. The at least one PCB 15 is coupled to a retaining heat sink 4 that in FIG. 2 is shown coupled to the luminaire's electronic device housing 22 (see FIG. 3). In this embodiment two crescent shaped PCBs 15 are included, along with a central hub that includes egress light sources 21, switch 27, and indicator lights 28.

(13) In FIG. 2 the orientation specific luminaire 5 is shown mounted above a racked aisle 10 (as shown in FIG. 5), and in FIG. 3 a perspective view of the luminaire 5 is shown. At the bottom face of the luminaire's electronic device housing 22 (FIG. 3) several power consuming devices are shown coupled. The devices shown include an emergency egress light source 21 (which itself includes multiple LED lamps as shown), a camera/occupancy sensor 23, and a transceiver 26. The transceiver may be wired or wireless, and provides signals to/from a controller that is also housed in the luminaire's electronic device housing 22. A plurality of electronic devices with different functionality are optionally coupled to the electronic device housing 22. These devices can couple to the electronic device housing by a plurality plug n play universal low voltage receptacles. The receptacles can be configured to convey only power, or power and data.

(14) Briefly touching on the emergency egress light source 21, FIGS. 2 and 3 show two such emergency egress light sources 21 coupled to the electronic device housing 22. Each of these devices has a directional light beam, the orientation of which is set by rotation to align over a path of egress. The two devices are arranged back to back to illuminate a linear path of egress on the aisle surface 1.

(15) Briefly touching on the occupancy sensor/camera with transceiver 23, in at least one embodiment the occupancy sensor/camera with transceiver 23 include one or more processors that provide image detection, and can identify a forklift stopped in its vicinity and cause the light to dim under condition the forklift it detected. Dimming the light reduces the eye strain of the forklift operator and can help avoid injury and/or damage. Similarly, a communication device coupled to the forklift automatically or an operator of the forklift manually can direct a luminaire in the immediate vicinity to dim its output light intensity.

(16) Other electronic features that can be integrated with the electronic device housing 22 include at least one of, an indicator light 28 and a switch 27. In at least one embodiment the switch 27 can control at least one of, a lighting circuit, light output, power input to a light source, color temperature of a light source, and/or associated other device/s with the light source/s such as an up-light lighting component.

(17) The orientation specific luminaire 5 shown in FIG. 2 includes a reflector/refractor 14 extending downwardly from a perimeter of the luminaire. While the optics of the orientation specific luminaire directs the output light from the LED lamps to meet all illumination requirements within an elongated space, architecturally in specifically retail spaces, a reflector, or a refractor appearance and/or added performance is often desired as a compliment. Thus, the present embodiments include the reflector or refractor and an optional accessory.

(18) Arrows in FIG. 2 represent light rays emanating from the specific orientation luminaire 5. The arrows represent a controlled approach to casting the luminaire's light within the elongated space 40. A portion of the light emitted is configured to illuminate the face of the racks of the vertical surface 2 and the remainder of the light emitted illuminate the floor surface 1 below. In at least one different embodiment (not shown), the orientation specific luminaire 5 can have an additional light source illuminating at least one surface above the luminaire 5.

(19) The illumination solution of the present embodiment employs a substantially horizontally disposed planar light emitting surface to illuminate both horizontal and vertical surfaces. Furthermore, the light delivered over the horizontal and vertical surfaces is precisely configured to fall where needed at the specified light level intensity. To achieve this fit, dedicated lensed optics are positioned above at least one LED lamp to direct light from the individual LEDs toward particular locations on the vertical surface. Overlap of separate light combine to provide a total luminance in respective subregions across the vertical surface.

(20) FIG. 2 shows two crescent formed PCBs 15 coupled to the orientation specific luminaire 5 heat sink 4. The PCBs 15 show a plurality of LED lamps 3 coupled with the lensed optics 24 (also see FIG. 3) disposed over the LED lamps 3. Each one of the PCBs 15 is configured to illuminate at least one vertical and horizontal surface 1, 2 (FIG. 5) from the orientation specific luminaire 5. In a different embodiment, one PCB or several PCBs with coupled LED lamps and lensed optics can equally illuminate these surfaces; however, for clarity the present figure shows the two crescent formed PCB's arranged about the longitudinal axis of the aisle surface 1 below.

(21) The distribution pattern of LED lamps around the PCB 15 are typically printed in concentric arcs (portions of a ring) about the vertical central axis of the PCB. Another approach that can be useful in designing and forming the lensed optics placed above the LED lamps 3 is orthogonal printing. For illustration purposes, the LED lamps 3 shown on the left side PCB 15 are printed concentrically, while the LED lamps 3 shown on the right side PCB 15 are printed orthogonally (e.g., in a grid array).

(22) The PCB/s with the coupled LED lamps and lensed optics above can be scaled up/down. The assembly can be detached from the luminaire wherein the luminaire can be fitted with a different PCB lamp/optics arrangement. Such an arrangement can configure different luminaire mounting heights and/or aisle widths. The arrangement of LED lamps with their respective lensed optics can zone the lamps differently, employ different lamp size, color temperature, lamp chromaticity and input power.

(23) Further, each PCB can have at least one power circuit and where more than one circuit is used, each circuit can be controlled differently or in unison. For example, referring to dimming a portion of the luminaire 5 light during stocking, when a sensing device such as an occupancy sensor and/or the camera with transceiver 23 sends a signal to the luminaire, only the circuit illuminating the horizontal aisle surface 1 is dimmed or turned off while the racked vertical surface 2 is fully or partially illuminated. The transceiver can also be separate from the camera.

(24) FIG. 3 shows a bottom perspective view of the orientation specific luminaire with a crescent form optical lens detached from the PCB with coupled LED lamps. FIG. 3 shows a partial view of a crescent shaped luminaire heat sink 4. The heat sink 4 is exposed and sized to receive a PCB 15 with a plurality of LED light source/s 3 and optics 24 over the PCB 15.

(25) On a bottom side of the exposed heat sink 4, there are two partial PCB 15 sections with coupled light sources 3 that are shown to be coupled to the luminaire's heat sink 4. Two partial lensed optics 24 shown below the PCB's 15 are configured to be positioned below and in proximity to corresponding light sources 3. The lensed optics 24 is key for delivering the specified light levels onto designated surfaces.

(26) For this reason, both the orientation specific and the non-orientation specific lensed optics is/are designed by computer modeling, with design variables including at least one of, luminaire mounting height, luminaire spacing, the horizontal distance from the luminaire's nadir to a vertical illuminated surface, luminaire distance from targeted horizontal and/or vertical light levels, the light emitted uniformity ratio on the horizontal and/or vertical surfaces, directivity of respective lens, and output levels from each LED. Composite light levels (overlapping light from different LEDs and corresponding lenses) set the illumination level experienced at particular subregions on the vertical surface and horizontal surface of the aisleway.

(27) FIG. 3 also shows a dedicated lensed optics 24 for each light source 3. In another embodiment a lensed optics 24 can be placed over a plurality of light sources 3 (not shown). Further, a plurality of light sources 3 can couple the PCB 15 of at least one of different, size, watt input, color rendition, and chromaticity (not shown).

(28) The light sources 3 coupled to the PCB 15 can be energized by at least one circuit (not shown). The plurality of circuits can control the light emitted by an individual PCB 15 or individual lights on the PCB 15. For example, during off hours, LEDs that emit UV light can decontaminate a space. The PCB 15 with its coupled light sources 3 and lensed optics can be detachable and replaceable by different lensed optics 24 as needed.

(29) FIG. 3 also shows the luminaire 5 with an electronic device housing 22, a cable/chain 6, an emergency egress light source 21, switches 27, an indicator light 28, and an IOT device (with a processor and memory, and optional a transceiver) as an occupancy sensor/camera 23.

(30) FIGS. 4a, 4b and 4c show by example three forms of optical lenses that can couple to an orientation specific and/or an orientation non-specific luminaire.

(31) The lensed optics 24 of the orientation specific and/or the non-orientation specific luminaire 5 can take any form. This also marks an optical design departure from art that provides generic light optical distribution by form of narrow, medium, and wide light pattern distribution. The lenses used with the luminaire 5 may be customized for an application while capable of illuminating at least one vertical and horizontal surface/s meeting light levels targeted.

(32) FIG. 4a shows two optical lenses 24 arranged about a central axis of a round opening. The lenses 24 in FIG. 4a can couple to two crescent shaped PCBs 15 with LED lamps arranged in correspondence to the coupled optical lens 24. At least one first optical lens 24 is configured to direct light toward a surface near by the luminaire and at least one second lens is configured to direct light to a remote surface wherein the optical arrangement of the at least one first optical lens 24 differs from the optical design of the at least one second optical lens 24.

(33) FIG. 4b shows a single square formed optical lens 24 that fits over a PCB with a polygonal-shape (e.g., square, rectangular, polygonal, etc.). Similarly to the crescent shaped lensed optics of FIG. 1a, the lens shown can be comprised of a plurality of lenses configured to direct the LED light emitted through the lens toward a pre-configured field of illumination below and/or at the side of the luminaire.

(34) FIG. 4c shows a rectangular lensed optics comprising two U shaped lenses abutting one another at their short legs. The U-shaped lenses fit over a U-shaped PCB that hosts the LEDs. Unlike the round and the square formed optical lenses that are symmetrical about their vertical central axis, the present rectangular lensed embodiment is asymmetrical. Further, the present example shows different sized lensed optics wherein the short leg of each section shows larger sized lenses.

(35) The exemplary lens configurations show that the light delivery form of a luminaire is not contingent on the luminaire form but rather what the light level intensity is expected at the face of a horizontal and/or a vertical subfield of illumination.

(36) FIG. 5 shows a conceptual zonal diagram for a light dispersion arrangement illuminating vertical wall/rack and horizontal floor surfaces of an elongated space. The orientation specific luminaire 5 is shown suspended by two cables/chains 6 over a racked aisle 10. The cable/chain 6 suspension elements are coupled to a mechanical orientation device 9 that is secured to a support structure 7 above. It is noted that the present arrangement converts a two-point mounting to a single point mounting. The luminaire's two-point mounting enables plumbing and orienting the luminaire regardless of the luminaire form. It also assures restoring the luminaire to its original orientation following colliding with a moving object.

(37) The single point mount can eliminate the need for a secondary support structure (not shown), saving material costs and installation production time. The present embodiment includes an orientation specific luminaire 5 with orientation specific optics and a mechanical orientation device that enables orienting the luminaire 5 in relation to at least one of, the longitudinal axis of the racked aisle 10 and a vertical surface of a rack face 2.

(38) FIG. 5 shows an adult human 20 traversing the racked aisle 10. Light rays emanating from the orientation specific luminaire 5 are shown directed toward subfields of illumination 8. The subfields of illumination 8 are quilted across the horizontal floor surface 1 and the vertical rack faces 2. The subfields of illumination 8 extend the full length of the racked aisle 10 wherein in a long aisle a plurality of orientation specific luminaires 5 are spaced apart at increments that enable adequate illumination coverage across the horizontal surface 1 and the vertical racked surfaces 2. In this example, the subfields are 2.5 high by 4 wide, although subfields of different dimensions may be used as well (e.g., heights varying between 6 to 6, and widths from 6 to 10).

(39) For graphic clarity the present figure shows the light rays 16 extending away from the orientation specific luminaire across only one half of the racked aisle 40. The light rays 16 also show only one vertical slice of light rays 16 extending from the aisle floor 1 to the top tier of the racked surface 2. The light rays illuminating the targeted subfield of illumination can overlap their illumination coverage onto at least one adjacent subfield of illumination 8. It is noted that precisely overlapping the illumination coverage over the subfields of illumination 8 can improve the illumination uniformity of the entire field of illumination.

(40) FIG. 6 shows a single point mechanical orientation mounting device for a luminaire with horizontal rotational capability. Moreover, this mechanical orientation mounting device may be used in conjunction with the orientation specific luminaire 5. A more detailed description of the mechanical orientation mounting device is provided in U.S. patent application Ser. No. 18/381,231, the entire contents of which is incorporated herein by reference. The present disclosure elaborates more fully on a system arrangement having the mechanical orientation mounting device 9, the luminaire 5 coupled below, and the suspension cable and/or chain 6 coupling the two elements.

(41) The mechanical orientation mounting device is configured for use with all luminaire forms requiring alignment, especially with luminaire lighting optical dispersion patterns that require an alignment with at least one of, a horizontal surface 1 and a vertical surface 2. In addition, in at least one embodiment, the mechanical orientation mounting device can include power or power and data conveyance circuit/s to the luminaire 5 and/or beyond (not shown).

(42) The mechanical orientation mounting device 9 can house a plug n' play power or power and data distribution device. Modular power or power and data conductors can then couple to the power/data distribution module from the exterior of the mechanical orientation mounting device 9 including a drop cable that can couple to the luminaire 5 (not shown). It is noted that the all in one system described above can provide luminaire orientation capability by a mono-point mounting device and power or power and data conveyance.

(43) The mechanical orientation mounting device 9 comprises two key elementsan alignment device flange 13 and a rotational disk 12. The alignment device flange 13 is affixed to the support structure 7 above. The rotational disk 12 is positioned above the alignment device flange 13 and is configured to rotate about the vertical central axis of the mechanical orientation mounting device 9.

(44) The rotational disk 12 at opposing sides of the flange 13 below, has elongated crescent shaped through bores arranged about the vertical central axis of the mechanical orientation mounting device (not shown). These elongated bores are configured to vertically align with through bores in the flange of the alignment device flange 13 (not shown).

(45) At least two suspension cables/chains 6 couple to the rotational disk 12. The suspension cables/chains 6 at their opposite sides couple to a luminaire 5. FIG. 6 shows the cables/chains 6 coupling directly to the rotational disk 12. In a different embodiment where large size luminaires and/or other voluminous objects are mounted to the mechanical orientation mounting device 9, extender arms 11 can be used. FIG. 6 shows the extender arms 11 disposed at 90? to the direct mount arrangement.

(46) FIG. 6 also shows alignment bolts 18 coupled to the bottom side of the alignment device flange 13. These bolts secure the alignment of the luminaire 5 in place. The bolts fixedly engage the rotational disk 12 to the alignment device flange 13 through their reciprocating bores. An installer installing a luminaire that requires a specific orientation can then either align and secure the rotational disk 12 in place or suspend the luminaire 5 first and then align and secure the rotational disk 12 in place.

(47) FIG. 7a shows a partial transverse section through a vertical surface showing with a conceptual vertical light level illuminance intensity (region shown with horizontal lines therein) in reference to an average adult human eye level. FIG. 7b shows a transverse section of a typical racked aisle in relation to the adult human eye level.

(48) FIG. 7a shows the intensity of the vertical illuminance on a vertical surface within an elongated space peaking at an adult human eye level 30, or adjacent to and above and/or below an adult human eye level, where the highest light intensity is needed. This light intensity peak occurs where it is needed in contrast with the intense light levels of present-day art shown in FIGS. 1a and 1b. The specific lensed optics of the orientation specific luminaire 5 mounted above the horizontal aisle surface 1 is configured to direct light from nadir outwardly in an asymmetrical pattern. In this example, the light intensity distribution has a peak level in a subzone (subfield) that is a height occurring at the height of eye level of an average adult human. The shape around the peak is generally Gaussian in distribution (i.e., bell curve), which is a result of overlapping light patterns directed toward the height of eye level of an average adult human, although having some dispersion about the peak level defined by a standard deviation 19 around the peak level as set by an overlapping of a relatively large number of dispersion patterns from respective LED/lens groups (e.g., pairs). A light level intensity below the inclusive range is no less than 0.6 times the light level intensity within the inclusive range.

(49) The exit angles of the emitted light, the lens light dispersion optical pattern, and the LED lamp intensity are set in relation to the height 25 of the vertical surface 2 that the orientation specific luminaire 5 is tasked to illuminate. FIG. 7a shows a ratio that is limited to maximum to minimum ratio of 3:1 between the highest and the lowest vertical illuminance on the vertical surface 2 vertically measuring across the full height 25 of the vertical surface 2 from the floor 1 up. For example, if the specified vertical light level target on a vertical surface of an elongated space is set for 30FC at the height of an adult human eye level within the inclusive range, the lowest vertical light level measured vertically across the same surface from the floor surface 1 up does not fall under 10FCas shown in FIG. 7a.

(50) It is noted that the structure of the present embodiment re-directs light from a light source from a horizontal planar surface of the orientation specific luminaire 5 onto a vertical surface 2 of an elongated space, concentrating the light emitted along a horizontal band 19 at a specific height above a floor 30 while maintaining an excellent maximum to minimum uniformity ratio of 3:1 across the entire surface of the vertical surface 2.

(51) FIG. 7b shows a transverse section of a typical racked aisle in relation to the adult human eye level. Visually pairing the side-by-side FIGS. 4a and 4b, one can see that the adult human eye 30 has a cone of vision of approximately 60? from the horizontal ?30? up and 30? down.

(52) Therefore, the eye coverage of an adult human looking straight at a vertical surface 2 of an elongated space illuminated by an orientation specific luminaire 5 falls on a higher vertical illuminance band extending across a portion of the vertical height 25 of the vertical surface 2. The vertical illuminance band width can vary based on the width of the horizontal aisle 1 and/or the placement of the orientation specific luminaire 5 above. However, the illumination ratios pertaining to the vertical illuminance on the vertical surface 2 of the elongated space can remain unchanged.

(53) FIG. 8a shows light exit angles above a luminaire nadir of a luminaire suspended above a surface of an elongated space. FIG. 8b shows the light exit angles of the same luminaire taken transversely across elongated vertical space.

(54) FIG. 8a shows two orientation specific luminaires 5 mounted above a horizontal aisle surface 1 illuminating a vertical surface 2. The luminaires' spacing H3 and mounting height H1 shown corresponds to the luminaires' light source output and the lensed optics arrangement. The present figure shows 45? to nadir 35 as the highest light exit angle from the luminaire 5. Light emitted by the luminaire 5 and directed toward the horizontal aisle surface 1 is configured to be glare free (<46? exit angle) and to uniformly illuminate the aisle surface 1.

(55) A scaled adult human traversing the horizontal surface of the elongated space aisle 1 is shown juxtaposed next to a high vertical surface 25. The vertical surface 2 represents a racked surface. The adult human eyes level 30 above the horizontal aisle surface is approximately 5-0 as shown in dashed line.

(56) The adult human cone of vision is approximately 60?. The eyes of an adult human looking straight at the rack 2 face perceive a vertical area centered at approximately the human eye level 30. The intense illuminance band extending the length of the vertical surface 2 face is formed by the adjacent surfaces above/below (dashed lines 19) the human eye level 30. The portion of the surface within the upper and lower dashed lines of horizontal band 19 is an illustration of the inclusive range.

(57) FIG. 8a illustrates that by dividing the light emitted through each luminaire 5 lensed optics into a horizontal surface and a vertical surface, the overall luminaire efficiency is increased. Limiting the horizontal surface 1 optical light exit angle of the luminaire 5 to a maximum of 45? reduces luminaire's optical losses and eliminates veiling glare, wherein the balance of the downwardly directed light of the luminaire 5, that includes high exit angle light rays, can then be directed away from the eyes of an adult human traversing the horizontal surface of the aisle 1 toward the vertical racked surface 2.

(58) FIG. 8b shows the light exit angles of the same luminaire as shown in FIG. 5a taken transversely across elongated vertical space. FIG. 8b shows the luminaire 5 mounted over an elongated space of a racked aisle 1. The luminaire 5 shown is positioned at approximately a mid-point of the aisles' width having the same illumination requirement on the faces of the racks 2, as the racks are equal in height. In a different embodiment (not shown), the light pattern emitted from one side of an orientation specific luminaire 5 can be different from the light emitted by the opposite side of the luminaire.

(59) FIG. 8b shows a symmetrical distribution of two luminaires' light emittance angles in reference to their respective nadirs 35. The luminaires are arranged in relation to at least one of, the vertical surfaces of the racks' face 2 and the central longitudinal axis of the elongated space racked aisle 1. The luminaire's lensed optics is shown to divide the emitted light into a component tasked with illuminating the horizontal surface 1 and a component tasked with illuminating the vertical surface 2 of the elongated space.

(60) The component tasked with illuminating the vertical surface 2 is further divided into two horizontal bands, one that illuminates vertical surfaces equal to or less than a 45? exit angle in relation to nadir, referred to herein as the low angle band, and the other band where the light exit angles in relation to nadir exceed 45? referred to herein as the high angle band. It is noted that the high angle band is higher than the eye level of an adult human 30.

(61) Further, a review of FIGS. 5a and 5b shows that the distance to the mid-point of a pair of luminaires 5 spaced apart H3 is relatively short in relation to nadir. That said, the proximity from the luminaire's nadir to the high band mid-point 34 vertical surface 2 is relatively short (see FIG. 5a crosshatched triangle). While high angle optics emitted through a horizontal planar surface facing downwardly can incur greater losses, the small area and the proximity to the luminaire 5 nadir 35 can offset these losses. In at least one different embodiment (not shown) at least one secondary non-horizontal planar surface with at least one light source coupled with a lensed optics can illuminate a vertical surface 2 more efficiently having a lesser light exit angle.
