    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).

    Abstract: An LED headlamp assembly (10) for a vehicle. The headlamp assembly (10) includes a plurality of LED units (14) mounted to a common carrier (16), where the LED units (14) include one or more LEDs and generate white light. The headlamp assembly (10) further includes a headlamp housing (28) that is mounted to the vehicle by a mounting frame (52). The carrier (16) is sealed to' the housing (28) by a flexible bellows (34). An outer lens (26) is mounted to the housing (28) so that the LED units (14) are positioned within a sealed compartment (42). A backside of the carrier (16) outside of the sealed compartment (42) includes fins (46) or other heat sinking devices t o remove heat generated b y the LED units (14). The frame (52) allows convective air to flow around the heat sink (46) to remove heat from the LED units (14). A series of actuators (56) and/or pivots (58) are mounted to the frame (52) and to the carrier (16) so that the carrier (16) can be moved on at least one axis to adjust the direction of the LED headlamp assembly (10).
