An optic for a light emitting diode array comprises an arrangement of optical structures for providing one or more down lighting distribution from the LED array; and a waveguide edge for providing one or more up-lighting distributions from the LED array. Luminaires are described comprising a light emitting diode (LED) array and the optic. Lighting systems are described comprising a plurality of the luminaires arranged over an area enclosed by walls.

A luminaire includes an enclosure, an air valve, and a chamber. The enclosure includes a sealed cover and light beam emitting components. The air valve is air coupled between the enclosure and the chamber. The chamber includes a drying agent and has an opening with a membrane completely covering the opening. The membrane passes air while reducing the passage of water droplets in the air. The air valve blocks air passage between the enclosure and the chamber when closed. A method for testing to determine adequate sealing of an enclosure of a luminaire includes closing an air valve to seal the enclosure from outside air, activating a heat-generating component, determining whether an air pressure in the enclosure increases by more than a threshold value, and sending a signal indicating a result of the determination. The method includes deactivating the heat-generating component and opening the air valve.

One or more reduced, same form, light emitting apparatus(es) spaced apart and configured to be mounted at various heights and/or spacing employ the same power consuming light source input that is covered by a symmetrical or asymmetrical redirecting linear lens optics apparatus that is configured for use in a range of mounting heights to uniformly illuminate at least one legal path of egress below.

A lamp for a vehicle forms a rear road surface pattern when the vehicle moves backward. The lamp for the vehicle includes a light source unit configured to generate light, a shield unit configured to selectively transmit a portion of the light generated from the light source unit, and a lens unit configured to concentrate the light transmitted through the shield unit onto a road surface. The lens unit includes a first lens part and a second lens part, and the second lens part includes an inner space through which the light emitted from the light source unit is transmitted.

An LED projection night light for night time or dark area use includes a plug-in wall outlet night light or direct current operated night light with projection features to project an image, message, data, logo, or time on a ceiling, walls, floor, or other desired surface. The LED night light incorporates optics-lens and Object with preferred focus calculation to create bigger image to shown on locations. The parts for make night light including but not limited as an optics-lens, slides, openings, or cut-outs, and/or a transparent material piece, translucent material piece, telescope assembly, housing-member, slide-film, slide-disc, elastic-member, tilt-means, rotating-means, adjust-means, roller-means, mechanical-means, extend-means, convex lens, and/or concave lens designed to make the desired image, message, data, logo, or time project to the ceiling, walls, floor, or other desired surface to be seen by a viewer. The LED light upgrade model has an interchangeable power source arrangement, permitting the night light to be selectively powered by either an AC powered sealed-unit or a DC powered battery-pack.

A system and method for visualizing, tracking and maintaining social distancing includes a visible boundary generating device having a lighting unit that is disposed within a main body, a user attachment mechanism and a controller for selectively communicating with an external processor enabled device. The lighting unit functioning to generate a visible zone of colored light in 360 degrees around a user to whom the device is secured. The visible light representing a safe zone having a radius that conforms to a specified social distance. The system also including a social distancing mobile application for execution on a smartphone or other processor enabled device. The social distancing mobile application including functionality for sending location information to a system administrator device, receiving proximity alerts from the system administrator device and providing notification to a user.

Example embodiments include modular lighting fixtures and methods for forming the same. Some include light emitters and base members with mounting locations for the light emitters, the light emitters and base members being combinable in varying combinations with each combination producing a different lighting effect. Some embodiments include a light guide, such as a planar light guide, that receives and redirects light from the light emitters. Additional embodiments include a reflector with portions that are positioned near a mounting location where no light emitter is mounted when the reflector is mounted to a base member. Further embodiments include a reflector with portions that are positioned near the mounting locations when mounted to a base member, the portions being easily removed, such as with an unpowered hand tool, to avoid interference with a light emitting member mounted adjacent to where the removable portion would be if not removed from the reflector.

Examples of the present disclosure disclose an optical element, a light source module using the optical element and a lighting device using the light source module. The optical element includes: a light distribution portion configured to receive irradiated light emitted from a light-emitting unit and allow the irradiated light to be emitted upon distribution, where the light emitted from the light distribution portion upon distribution has an irradiation range; and a light-shielding portion provided integrally with the light distribution portion, where the light-shielding portion is engaged with the light distribution portion to form a light-shielding receiving chamber, and the light-shielding receiving chamber is located outside the irradiation range.
