Abstract:
A package structure of a compound semiconductor device comprises a thin conductive film with a pattern, a die, at least one metal wire or metal bump and a transparent encapsulation material. The die is mounted on the first surface of the thin conductive film, and is electrically connected to the thin conductive film through the metal wire or the metal bump. The transparent encapsulation material is overlaid on the first surface of the conductive film and the die. A second surface of the conductive film is not covered by the transparent encapsulation material, and is opposite the first surface.
Abstract:
In a light emitting device package and manufacturing method thereof, a multi-layer structure is allocated upon a substrate, of which at least two films with different refractive indices are alternately stacked together.
Abstract:
A planar lighting module comprises a substrate, at least one light guide device and a driver. A frame is located on the substrate for fastening the at least one light guide device and the driver. By manipulation and binding, the planar lighting module can be easily assembled or dismantled, no screws or welded joints are used, and it is also convenient to service.
Abstract:
An exemplary LED bulb includes a holder, a housing, a heat spreader, a power module and an LED module. The housing connects to the holder. The heat spreader detachably engages with the housing. The power module detachably engages with the housing and is received in the housing. The LED module is arranged on the heat spreader. The LED module electrically connects to the holder via the power module. The LED module is physically separated from the power module.
