A luminaire featuring a light diffusing housing assembly with a batwing style catadioptric lens element with properties capable of producing a more uniform field of illumination in concert with a secondary diffusing lens element and optional internal light reflecting elements to maximize light output from a point light source including an LED, or a plurality of individual point light sources including an LED strip or LED array and other source of linear chromatic light or linear illumination sources including a light bar, fluorescent lamp, compressed-gas discharge tube and the like.

Arc modular light devices, systems, and methods. In at least one exemplary embodiment of a module system of the present disclosure, the module system comprises a plurality of LED modules, each LED module comprising an outer housing, a light source positioned within the outer housing, and a lens positioned so that light from the light source can be emitted through the lens; and a plate configured to couple to each of the plurality of LED modules; wherein the module system is configured to focus light from the LED modules inward when the plate has a concave curvature; and wherein the module system is configured to spread light from the LED modules outward when the plate has a convex curvature.

First adapter (10) and second adapter (40) are each separately securable to a respective automotive light bar (200, 201) at mutually facing lateral light bar end caps (206). The adapters (10, 40) interfit, such as first adapter (10) having one or more tenons (14; 18) received in shape-conforming recess or mortise (44) of second adapter (40). The coupling assembly formed from interfit first and second adapters (10, 40) sufficiently supports a midspan region of conjoined light bars (200, 201) to permit omission of mounting L-brackets (208) conventionally required at the mutually facing light bar ends (206), thus allowing fewer holes to be drilled in vehicle roof or bumper (212) and resulting in an aesthetically cleaner presentation of the overall lengthened light bar assembly.

A seamless lighting arrangement for a vehicle panel. The vehicle panel has an inside surface and an outside surface. The vehicle panel has a light aperture extending from the inside surface of the vehicle panel to the outside surface of the vehicle panel. Connected to the inside surface of the vehicle panel is a bracket. The seamless lighting arrangement further includes a lens with a bracket connection portion that connects to the bracket and a transmission portion positioned within the light aperture of the vehicle panel. The lens further includes a light unit fixedly connected to the lens. The light unit has a projector port for emitting light from a light source. The light transmission portion of the lens has a light input surface region formed on an inside surface of the lens and a light output surface region formed on an outside surface of the lens.

A light fixture, such as but not limited to an outdoor light fixture, may include features or elements allowing for enhanced resistance to water ingress and/or enhanced thermal management of components. Such features or elements may be provided between a housing of the light fixture and a lens of the light fixture and/or between the housing of the light fixture and an end cap of the light fixture. Some features or elements may limit thermal expansion and contraction of a lens of the light fixture over a wide range of temperatures.

A lighting assembly includes a lightbulb, sleeve, motor assembly, a control circuit, power source, first state, and second state. The control circuit is communicatively coupled to the power source, the lightbulb, and the motor assembly. The lightbulb emits ultra violet (“UV”) radiation. The sleeve converts UV radiation to visible light, is circumferentially positioned about the lightbulb, and is rotatably coupled to the lightbulb via the motor assembly. The motor assembly is mechanically coupled to the sleeve, and selectively rotates the sleeve about the lightbulb and thereby positions the lighting assembly in the first state or the second state. The sleeve includes a slit that emits the UV radiation from the lightbulb. In the first state, the lighting assembly emits UV radiation towards a surface. In the second state, the lighting assembly emits visible light towards the surface.

A mount for coupling a lighting fixture to a hanging structure includes an upper section adapted to attach to a pendant or other hanging structure and a lower section adapted to attach to the lighting fixture. The upper section includes an elongate rack and a pair of knuckles. The lower section including an elongate hanger for engaging with the elongate rack to support the lower section and the lighting fixture, including when the lower section is in an open position relative to the upper section during installation and wiring. The lower section also includes a knuckle. A locking member selectively engages the three knuckle to lock the lower section in a closes position relative to the upper section. The mount can further include removeable end covers for enclose opposite ends of the upper section.

To provide a light guide plate with reduced luminance unevenness. The light guide plate includes: a base portion having a one surface and a light incident surface disposed on one end side of the one surface and intersecting the one surface, and a plurality of convex lenses provided on a side facing the one surface of the base portion, each of the plurality of convex lenses extending in a first direction and aligned along a second direction which is substantially orthogonal to the first direction, where the base portion includes at least a first region relatively close to the light incident surface and a second region relatively far from the light incident surface, and where the first region is provided with a plurality of first bottom portions that are surfaces disposed between the convex lenses adjacent to each other in the second direction and inclined with respect to the first direction.

A light bulb apparatus includes a bracket, a flexible light strip, a bulb shell, a central base and a driver. The bracket includes a central bar and multiple top hooks. The multiple top hooks have first ends connected to the central bar. The flexible light strip has multiple first bending points fixed to second ends of the multiple top hooks for expanding the flexible light strip. a bulb shell. A driver for converting an external power source to a driving current. The central base encloses a part of two wires. The central base exposes first electrodes of the two wires for connecting to the flexible light strip. The central base exposes second electrodes of the two wires for receiving the driving current. The central base and the bulb shell form a closed space for holding the flexible light strip and the bracket.
