The first twist-lock connector includes a biasing member coupled to the first high speed electrical connector to bias the first high speed electrical connector to the home position. The twist-lock connector system includes a second twist-lock connector having a second connector housing holding second twist-lock contacts and a second high speed electrical connector at a mating interface.

A lighting device including at least one first light source emitting a visible light, at least one second light source spaced apart from the first light source and emitting a light having a wavelength for sterilization, and a housing, in which the first light source and the second light source are disposed, in which the first light source is disposed outside an area having an angle corresponding to about 50% of a maximum amount of light emitted from the second light source based on a line extending from a center of the second light source along a direction substantially perpendicular to a light emitting surface of the second light source.

A lighting assembly that includes a heatsink housing, a plurality of light emitting diode (LED) modules, and a power supply disposed within a power supply casing, wherein the power supply is for providing power to the LED modules. Each LED module includes a plurality of LEDs and is thermally connected to the heatsink housing. The power supply casing includes a structure for cooling the power supply.

In one aspect, luminaires are described herein having sensor modules integrated therein. In one aspect, a luminaire described herein comprises a light emitting face including a LED assembly. A sensor module is integrated into the luminaire at a position at least partially overlapping the light emitting face. In another aspect, a luminaire described herein comprises a LED assembly and a driver assembly. A sensor module is integrated into the luminaire along or more convective air current pathways cooling the LED assembly or driver assembly.

The disclosure relates in general to illuminated panels resembling windows, and more particularly, to a system containing a light source, a diffuser and a panel combined in such a fashion as to resemble a window, skylight or curtain wall.

A vehicular exterior door handle assembly includes a base portion configured to mount at an exterior door handle region of a vehicular door of a vehicle, a handle portion, and a sensing module that includes a light emitter and a light sensor. With the base portion of the handle assembly mounted at the exterior door handle region of the vehicular door, the light emitter is episodically energized to emit light. When the light emitter is not energized to emit light, the light sensor senses ambient light at the handle portion, and when the light emitter is energized to emit light, the light sensor senses emitted light emitted by the light emitter. The sensing module determines presence of a person's hand at the handle portion based at least in part on a difference between the sensed ambient light and the sensed emitted light being below a threshold light level.

A lighted railing assembly with at least one railing member includes an inner cavity, a battery disposed within the inner cavity and a lighting device powered by the battery. A solar panel is integrated into the railing member and is electrically coupled to charge the battery. A controller is configured to control charging of the battery and activation of the lighting device in response to a signal provided by an ambient light sensor.

A solar light stick for use in illuminating and decorating a lawn, garden or pathway. The solar light stick includes a supporting stake, a solar panel, a rechargeable battery, at least one LED, and a tube body. The tube body contains a light transmissive material that may be transparent or translucent. The solar panel charges the rechargeable battery which, in turn, provides power to the LEDs. The LEDs are positioned to provide light to the interior of the tube body. As such, the LEDs may be located within a recess in the tube body. Reflective flakes dispersed within the tube body reflect and disperse light from the LEDs in a decorative manner.

A portable illumination device, including a main body, an illumination unit movably disposed on at least a portion of the main body to emit a beam of light and illuminate a surrounding area, at least one sensor disposed on at least a portion of the main body to turn on the illumination unit in response to detecting an external condition, and a surface fastener disposed on at least a portion of the main body to removably connect the main body to an external surface.
