The optical apparatus includes a first light source, a second light source, and at least one lens unit. An incident surface of the lens unit faces the first light source and the second light source. The normal vector of a first emitting surface of the first light source is tilted toward a first direction opposite to the second light source. The normal vector of a second emitting surface of the second light source is tilted toward a second direction opposite to the first light source. The first direction is opposite to the second direction such that an angle is formed between the normal vector of the first emitting surface and the normal vector of the second emitting surface. The angle is greater than 0 degree and less than or equal to 90 degrees.

An LED high bay light comprises a plurality of LED illuminant engines arranged abreast and alternately; each of the LED illuminant engine comprises an LED strip-shaped illuminant and an optical lens set covering the LED strip-shaped illuminant; the optical lens set comprises a plurality of strip-shaped optical lenses arranged conterminously; and two adjacent strip-shaped optical lenses are connected to each other through a mutual cooperation of the stepped spigots arranged oppositely. Each illuminant engine thereof adopts a structure of strip-shaped optical lens set with multiple sections, greatly reducing the difficulty in making molds and the cost for manufacturing parts.

A vehicle lamp includes a light source including a plurality of light emitting elements or light emitting surfaces, a projection lens that projects light emitted from the light source, and a light distribution adjusting element that adjusts light distribution of the light emitted from the light source, wherein the light distribution adjusting element has a plurality of prisms having different angles of inclined surfaces corresponding to a direction in which the plurality of light emitting elements or light emitting surfaces are arranged, and prism surfaces in which at least one or a plurality of flat surfaces are arranged.

Disclosed embodiments relate to a combination axial fan and LED lighting system configured to fit into the footprint of a standard ceiling tile. Disclosed embodiments further include ceiling tiles with a built-in fan and/or LED lighting. The disclosed systems may include a housing container and an axial fan. The fan has a fan cavity including air diversion mechanism to direct air from the fan cavity toward the lighting and fan components. The inventions include an airflow surface to direct air existing the fan cavity along an LED light fixture. Moreover, disclosed embodiments include one or more UV light sources which irradiate contaminants as air flows through the ceiling tile.

A laser lighting system has a first laser light source, a second laser light source and a light conversion element. The outputs from the first and second laser light sources are directed to the light conversion element, which generates wavelength-converted light output in response to excitation by laser light. The first and second laser light sources generate laser light of different wavelength having different absorption characteristics within the light conversion element, such that the range of depths within the light conversion element from which wavelength-converted light is generated is different. This difference in converted output can be used to create different optical effects so that beam steering or beam shaping can be performed.

Provided is a light fixture comprising: a) a body, the body having a central portion and two side portions, each of the two side portions situated on one side of the central portion, the two side portions and the central portions running parallel to each other, the central portion recessed in an upward direction in relation to the two side portions, the recess of the central portion forming a ballast room inside of the body; b) two end caps, each end cap attached to an end of the body; c) a plurality of LED (light emitting diode) boards attached to an inside of the side portions of the body; d) one or more ballasts inside of the ballast room; e) a ballast room cover for covering the ballast room; and f) two rectangular-shaped lenses, each lens covering the LED boards attached to the side portion of the body. Each lens can contact the body on one of its long sides and contact the ballast room cover on its other long side.

A cable management system may comprise a longitudinal trough with a plurality of lights disposed on an underside of the trough. A power connector may be disposed at an end of the trough communicatively coupled to the plurality of lights. The cable management system may also comprise a second trough or one of a plurality of cable management components, each with a plurality of lights disposed on an underside and a power connector communicatively coupled to the pluralities of lights. The first trough, the second trough, and/or the plurality of cable management components may mate together to form a continuous circuit.

An LED lamp retrofit system, kit, and method is presently disclosed. The LED retrofit system comprises at least one longitudinally extending LED lamp having a length substantially greater than a width and open longitudinal ends. A first LED lamp support rail holds and covers a first open longitudinal end of each of the at least one longitudinally extending LED lamps and is configured to electrically connect each of the at least one longitudinally extending LED lamps to a power source. A second LED lamp support rail holds and covers a second open longitudinal end of each of the at least one longitudinally extending LED lamps held with the first LED lamp support rail. A system holder on each of the first and second LED lamp support rails is configured and disposed to hold the retrofit system to a portion of a lamp fixture being retrofitted.

A luminaire includes a door frame assembly that comprises an end plate. The end plate includes a top edge and a bottom edge that is opposite to the top edge, where the end plate extends from the bottom edge to the top edge. Further, the end plate includes a notch. Furthermore, the end plate may include a light redirecting flange that may be coupled to or integral with the end plate. The light redirecting flange may be positioned adjacent the notch in the end plate and at an angle with the end plate to redirect light from a light source of the luminaire that exits through the notch back towards a lens of the luminaire.

A system and method for creating a trompe-l'oeil skylight in a ceiling where a light emitting image of the sky is provided in a structure configured to emulate a skylight frame, including an embodiment of a unified non-rectangular sky image area in a substantially rectangular fixture which mount as a single unit into a substantially rectangular hole in a ceiling.
