Patent ID: 8246203

Claim:
A light comprising: mating front and back housings, between them defining a one-dimensional thickness of the light; said housing including at least one of a side aperture and back aperture; a circuit board mounting circuit elements and interconnecting conductive tracks to which LED devices are connected; and a minimum power-rating two-core mains electricity cable passing through at least one of the side aperture and the back aperture, the conductors of which cable are fixed to said circuit board; wherein the circuit board is enclosed and sandwiched between said front and back housings; said front housing transmits light emitting from said LED devices; said circuit elements and LED devices are arranged to be powered by AC mains electricity; and said one-dimensional thickness is no greater than 25% more than the sum of the thicknesses of said front and back housings and the power cable, and not less than the thickness of said cable, wherein said housings define a rim region of the light surrounding the circuit elements on the circuit board, wherein labyrinth flanges are formed on one of said front and back housings in said rim region whereby said cable, on passing into the light through one of the apertures, passes along a labyrinthine path around said rim defined by said labyrinth flanges, and wherein said front housing has a central region that is opaque that covers circuit element regions of the circuit board that do not include said LED devices, and a peripheral translucent or transparent region that covers LED device regions of the circuit board.
