An LED light source apparatus includes a lamp housing, a lighting module, and a lens. The lamp housing has a first shell body, a second shell body, and a waterproof pad disposed between the first and second shell bodies. The first shell body and the second shell body are covered to each other. The second shell body has an opening. The waterproof pad is provided with a throughhole corresponding to the opening. A light guide flap is disposed on the perimeter of the opening of the second shell body. The lighting module is disposed inside the lamp housing corresponding to the opening. The lens is installed on a side of the lamp housing corresponding to the lighting module. Therefore, the components or the lighting module with a different power can be conveniently replaced by modules and thus the present invention has the flexibility in replacement and maintenance.

A luminaire includes an adjustable torsion spring assembly for mounting the light engine assembly to a mounting frame and for providing the ability to conduct maintenance of the light engine assembly. The luminaire may include a mounting frame assembly; an light engine assembly engaged with at least a portion of the mounting frame assembly, the light engine assembly comprising at least one light source configured to emit light; and a support wire adjustably-coupled at a first end to a side of the light engine assembly, the support wire extending in the first direction from the side of the light engine assembly, and comprising at least one hook at a second end.

A lighting and energy conservation system for low temperature applications includes LEDs as a light source. The LEDs are provided in a modular LED light fixture. The fixture includes a frame supporting a reflector having a plurality of elongated channels. Mounting strips are removably installed in each of the elongated channels, and LEDs are mounted on each of the mounting strips. A separate power control device is associated with each of the mounting strips, so that a total light output intensity and profile of the fixture can be individually customized by selectively adjusting the power control device for each of the mounting strips.

Multi-function lighting fixtures are provided. In one example implementation, a lighting fixture may include an optical housing extending lengthwise between a first end and a second end. The optical housing may include a plurality of light sources disposed within an interior of the optical housing and a plurality of optical elements disposed along an exterior of the optical housing. The optical housing may also a plurality of compartments defined within the interior of the optical housing. Each of the optical compartments may be associated with a separate light source of the plurality of light sources and a separate optical element of the plurality of optical elements.

An LED light installation device facilitates removal and installation of LED type lights into can light housings in an elevated position. The device includes a collar having a first end. The first end is open wherein the collar is configured for receiving an extension pole into the first end. A plate is coupled to a second end of the collar. The plate has a planar upper surface. Each of a plurality of projections is coupled to and extends outwardly from the upper surface of the plate wherein the projections are configured for extending through gaps in a heat sink portion of an LED light when the LED light rests on the upper surface of the plate.

The invention relates a LED lamp. The LED lamp includes: a sleeve; a female joint received in the sleeve; a pluggable connector rotatably connected to the sleeve; a LED tube connected to the pluggable connector; and a male joint received in the pluggable connector and engaging the female joint; wherein the pluggable connector is provided with a plurality of clips on an outer sidewall thereof extending towards the LED tube, the clip is provided with a protrusion, the sleeve defines an annular groove on an inner wall thereof, the protrusion is latched in the annular groove when the pluggable connector is inserted into the sleeve, thereby preventing the pluggable connector from disengaging from the sleeve.

A flat panel lighting apparatus, which makes it easy to replace a circuit board with LEDs thereon, is provided. The flat panel lighting apparatus includes a backplate, a driving unit, a light guide plate, a frame, a bracket, a circuit board, a connector and a cable connecting the driving unit and the circuit board. The frame with an opening portion is disposed at an outer periphery of the backplate and the light guide plate. The bracket is detachably coupled to the opening portion of the frame. The circuit board with light sources, is disposed in a space between the frame and the light guide plate, and is replaceable in a sliding type through the opening portion of the frame when the bracket is decoupled from the frame. The connector has a female terminal attached to the circuit board and a male terminal detachably coupled to the female terminal.

The invention is an apparatus for connecting and disconnecting light bulbs including a suction cup and at least one structure for interrupting suction to the suction cup.
