Abstract:
A light emitting device comprising:a phosphor layer having two opposing sides including one or more excitable, light-emitting phosphors; a radiation source positioned adjacent a first one of the two opposing sides of the phosphor layer for providing a radiation to excite a light emission from the phosphor layer, the radiation source having a first contact region and a second contact region; reflector means provided adjacent a second one of the two opposing sides of the phosphor layer for reflecting at least some of the radiation and light emission that exits from the phosphor layer back into the phosphor layer; and wherein said reflector means comprises a first contact layer positioned over at least part of the phosphor layer, the first contact layer being at least partially reflective and at least partially electrically conductive, said first contact layer being electrically connected to the first contact region.
