    Abstract: An LED unit (20) having increased light output. The LED unit (20) includes a submount substrate (22) having a cavity (24). An LED chip (30) is electrically mounted within the cavity (24) and a phosphor layer (34) is deposited in the cavity (24) that converts blue light from the LED chip (30) into white light suitable for a vehicle headlight (10). The walls of the cavity (24) are metalized (40) to increase the light output intensity. In one embodiment, a clear protective layer (46) is deposited in the cavity (24) over the phosphor layer (34).
