A light fixture includes a housing having a first side and a second side opposite the first side. The light fixture further includes a first light board coupled to the first side. The first light board has at least one light emitting element emitting a first light output in a first direction. The light fixture further includes a second light board coupled to the second side. The second light board has at least one light emitting element emitting a second light output in a second direction. The light fixture further includes a first driver supported by the housing and in electrical communication with the first light board. The first driver is operable to control the first light output. The light fixture further includes a second driver supported by the housing and in electrical communication with the second light board. The second driver is operable to control the second light output.

An integrated lamp is provided, including: a shell member, defining a mounting space; a light-evening member, disposed within the mounting space, including an incident portion and a light-penetrable region; a first LED unit, disposed within the mounting space, at least part of light from the first LED unit being incident into the incident portion and diffused within the light-penetrable region to become a surface light source; a second LED unit, disposed within the mounting space, overlapping with the light-penetrable region, configured to light to form at least one point light source; wherein the light form the first LED unit and the light form the second LED unit emit out from the light-penetrable region, at the same time or respectively.

A combination axial fan and LED lighting system configured to fit into the footprint of a standard ceiling tile. The system includes 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 invention includes an airflow surface to direct air existing the fan cavity along an LED light fixture.

A retrofitting kit includes at least one of an adapter bracket and a retainer configured to engage at least one of an existing troffer light fixture and a T-bar of a ceiling system and a door assembly configured to be held in the ceiling system by the at least one of the adapter bracket and the retainer. The door assembly has a housing, the housing including one or more sidewalls, where the one or more sidewalls extend upward to define a cavity, and a plurality of LEDs having primary light axes extending inward into the cavity. The plurality of LEDs are coupled to the one or more sidewalls and positioned to illuminate at least a portion of the housing from behind with a uniform distribution of light when engaged.

An LED board rail for retrofitting a fluorescent light fixture includes an LED board having a plurality of LEDs, and an elongated optical cover housing the LED board along its length, where the elongated optical cover has a first end and an opposing second end. The LED board rails also includes a first spring clip having a first finger and an opposing second finger, and a second spring clip having a first finger and an opposing second finger. The first and second spring clips are configured to engage respective first and second slots formed into a ballast cover of the existing fluorescent light fixture for first and second lamp holders.

A smart vehicle treatment system includes a vehicle treatment device configured for movement along multiple degrees of freedom, such as rotation and translation. A plurality of activatable components, such as lights and/or actuators, are disposed on the treatment device and controllable by one or more sub-controllers disposed on the treatment device. The sub-controllers receive a multiplexed communication signal from a main controller located remote from the treatment device. The multiplexed communication signal and power are transmitted through a movement mechanism that provides the multi-degree of freedom movement. The movement mechanism may include a slip ring, which electrically connects the main controller to the sub-controller on opposite operative sides of the movement mechanism. Multiple individually activatable components can be selectively activated on the treatment device via the multiplexed communication signal.
