DETAILED DESCRIPTION
[0053] As discussed above, inexpensive white light emitting diodes (LEDs) generally are constructed as white phosphor-converted LEDs where a blue LED is covered with a phosphor coating that converts a portion of the blue light from the LED to yellow light so as to create white light. Conventional lighting devices are typically constructed with a set of such white LEDs (all with the same construction) that are connected to a common power source.
[0054] The inventors have that such conventional lighting devices are generally only able to emit light with a single, fixed set of characteristics (e.g., light distribution, color correlated temperature (CCT) value, color, etc.). While such conventional LED strip lighting devices may be suitable for hobbyist use, commercial establishments may have different demands. Commercial establishments may want to customize the light distribution, CCT, and/or color of the light from the lighting device.
[0055] Accordingly, aspects of the present disclosure relate to lighting accessories that are configured to change at least one characteristic of the light from the lighting device. In some embodiments, a lighting system may be provided that comprises a strip lighting device, a fixture into which the lighting device may be disposed and/or mounted, and a lighting accessory that is configured to removably couple to the lighting fixture over the strip lighting device and change at least one characteristic of the light from the strip lighting device. Thus, the characteristics of the light from the strip lighting device may be customized to suit any of a variety of situations by coupling different lighting accessories to the fixture.
[0056] In some embodiments, the strip lighting device may comprise a tray with a base and a plurality of sidewalls that extend from the base (e.g., extend in a direction that is perpendicular to the base), a circuit board disposed in the tray (e.g., disposed and/or mounted to a surface of the base of the tray), an LED mounted to the circuit board, and an elastomer (e.g., silicone, rubber, etc.) encapsulating at least part of the circuit board and being in contact with the tray. In these embodiments, the strip lighting device may further comprise a lens assembly that is disposed above the LED and configured to change at least one characteristic of the light from the LED. The lens assembly may comprise at least one optical element such as a lens, a reflector, and/or a light scattering element. For example, the lens assembly may comprise only a lens. In another example, the lens assembly may comprise a lens and a reflector. The lens assembly may be attached to the strip lighting device via the circuit board (e.g., the lens assembly may be mounted to the circuit board) and/or the elastomer that at least partially encapsulates the circuit board (e.g., the elastomer may be in direct contact with at least part of the lens assembly). The strip lighting device may be designed to have any of a variety of dimensions. For example, the strip lighting device may a length of no more than approximately 6 inches, a width of no more than approximately 3 inches, and a height of no more than approximately inches.
[0057] In some embodiments, the fixture may be configured to receive the strip lighting device and mount to a structure. The structure may be, for example, a ceiling, an interior wall, an exterior wall, a floor, or a railing. The fixture may be constructed from a metal such as aluminum, brass, copper, steel, and iron (or any combination thereof). The fixture may comprise a tray including a surface to receive the strip lighting device and a plurality of sidewalls that at least partially capture the strip lighting device within the tray. The tray may further include a rail disposed on at least one of the sidewalls and configured to removably couple to the lighting accessory.
[0058] In some embodiments, the lighting accessory may be configured to removably couple to the fixture over the strip lighting device and change at least one characteristic of the light (e.g., distribution, CCT value, and/or color) from the strip lighting device. The lighting accessory may be implemented in any of a variety of ways. For example, the lighting accessory may comprise a light filter (e.g., implemented as a pigmented elastomer) configured to change a CCT value of the light from the strip lighting device. In another example, the lighting accessory comprises a light louver configured to change a distribution of light from the strip lighting device. In yet another example, the lighting accessory comprises a barn door assembly configured to change a distribution of light from the strip lighting device and including a plurality of barn doors rotatably coupled to the fixture. In still yet another example, the lighting accessor comprises a mirror assembly configured to change a distribution of light from the strip lighting device and including a mirror that is configured to rotate about at least one axis to change the distribution of light from the strip lighting device.
[0059] It should be appreciated that the embodiments described herein may be implemented in any of numerous ways. Examples of specific implementations are provided below for illustrative purposes only. It should be appreciated that these embodiments and the features/capabilities provided may be used individually, all together, or in any combination of two or more, as aspects of the technology described herein are not limited in this respect.
Example Lighting Systems
[0060]
[0061] The lighting device 102 may comprise a plurality of lens assemblies 106 disposed over the LEDs. The lens assemblies 106 may each comprise at least one optical element such as a lens, a reflect, and/or a scattering element. The lens assemblies 106 may change at least one characteristic of the light emitted from the LEDs. For example, the LEDs may be phosphor converted LEDs that emit light with an angular CCT deviation. In this example, the lens assemblies 106 may receive light from the LED and make the color temperature of the light more uniform. Additionally (or alternatively), the lens assembly 106 may adjust a light distribution pattern of the LED. For example, the lens assembly 106 may create a circular beam of light or an oblong beam of light. Example implementations of the lens assembly 106 are described in detail in U.S. Patent Publication No. 2017/0261186, titled LIGHTING SYSTEM WITH LENS ASSEMBLY, published on Sep. 14, 2017, which is hereby incorporated herein by reference in its entirety.
[0062] It should be appreciated that various alterations may be made to the lighting system 100 without departing from the scope of the present disclosure. For example, the lens assemblies 106 may be removed and, thereby, directly expose the LEDs under the lens assemblies 106. An example of such a lighting system without lens assemblies is described in U.S. Patent Publication No. 2016/0201861, titled FLEXIBLE STRIP LIGHTING APPARATUS AND METHODS, published on Jul. 14, 2016, which is hereby incorporated herein by reference in its entirety.
[0063]
[0064] The circuit board 208 may be electrically coupled to other components using the connector 104 that may be implemented as a female connector 201 or a male connector 202. The female connector 201 comprises a cavity 204 with multiple contacts 206. The cavity 204 may be configured to receive a plug of a corresponding male connector (e.g., male connector 202). The male connector 202 may comprise a plug 203 with contacts 206 disposed on a bottom surface of the plug 203. The plug 203 may be constructed to be inserted into a female connector (e.g., female connector 201).
[0065] In some embodiments, the lighting system may further comprise a lens assembly (e.g., separate and distinct from any lens assembly integrated with the lighting device) that includes a lenticular lens that is disposed above the lighting device. A cross-sectional view of such a lighting system is shown in
[0066] In some embodiments, the lens assembly 302A may be coupled to the lighting device using a mechanism separate and apart from the notch 209. For example, the lens assembly may be attached to a top surface of the lighting device as shown by lens assembly 302B in
[0067] It should be appreciated that the lens assemblies 302A and/or 302B may be constructed from any of a variety of materials. For example, the lens assemblies 302A and/or 302B may be constructed from one or more of the following materials: plastic (e.g., acrylic or polycarbonate), glass, and silicone. Further, the lens assemblies 302A and/or 302B may be monolithic elements.
