A lighting device includes: a bearing member, provided with a circuit switching component, wherein the circuit switching component is connected to an external power supply, and is provided with at least one first plug portion; and at least one light source component, comprising: a housing, provided with a first accommodation portion and a second accommodation portion; one or more light source units, each light source unit has one or more pairs of power supply pins; a drive circuit component, comprising a second plug portion, the drive circuit component is used for switching the external power supply into supply power to the light source unit; and a conductive member, provided with through holes for inserting the power supply pins, wherein the conductive member is in conductive contact with each electrical connection pin.

Light fixtures often have bright spots caused by the light sources that can be unpleasant or uncomfortable to look at. A light device is provided that diffuses the light, which includes an internal cavity defined in the body of a flexible shroud extending transversely from an opening defined in a first end frame to an opening defined in a second end frame of the shroud. The first and the second end frames are removably connectable to each other to form a circular configuration of the flexible shroud. The internal cavity also extends in the circular configuration. A light board is attached to one of the end frames and at least partially covers the opening of the given end frame. In the circular configuration, the light board is sandwiched between the first and the second end frames.

An electrical connection device connects to a sectional door, the sectional door having a plurality of connected panels which roll along left and right tracks which are connected to a structure, the sectional door is positionable to a closed position and to an open position. The electrical connection device includes a slide which carries a reciprocating electric contactor. A housing has a slot, a proximal end and an opposite distal end. The slide slides along the slot in the housing. A spring in the housing biases the slide toward the distal end of the housing. The housing is connectable to either the left track or to the right track of the sectional door.

An edge-lit downlight apparatus includes a surface housing having a base and a side wall, a laminate, and a light guide module. The downlight apparatus includes a circuit board having an inner and an outer surface wall. The downlight apparatus includes first brackets, and each includes a body and a contacting part. The body of the first bracket abuts against the side wall of the surface housing, and the contacting part of the first bracket extends outward from the body and abuts against the laminate. The downlight apparatus includes fasteners passing through the contacting parts of the first brackets, the laminate, and being removably connected to the surface housing. LED chips are located on the inner surface wall of the circuit board.

A luminaire for an inductive power transfer lighting system includes a luminaire body having a base and a hinged lid. A seal has a first sealing surface mounted in the base and a second sealing surface mounted in the lid. The first sealing surface includes a first power cable receiving channel running from one side of the base to an opposite side. The second sealing surface includes a corresponding second power cable receiving channel. When clamped together by clamping means the lid and base are sealed together and the power cable receiving channels co-operate to form a bore for holding a power cable. At least one of the sealing surfaces includes at least one groove transverse to the direction of the bore.

An assembly is provided herein for a lighting fixture and for retrofitting a flush mounted light fixture to be provided with solid state lighting.
