Patent ID: 7214969

Claim:
A wavelength-convertible light emitting device comprising: a semiconductor Light Emitting Diode (LED) having a first and second surfaces opposed to each other, and including first and second conductivity-type cladding layers and an active layer formed between the first and second conductivity-type cladding layers to emit a specific wavelength light; at least one piezoelectric layer disposed on at least one of the first and second surfaces of the semiconductor LED, with its thickness variable according to the applied voltage; a rigid frame made of substantially non-resilient rigid material, which surrounds the semiconductor LED and the at least one piezoelectric layer such that the increase of the thickness of the piezoelectric layer is applied to the semiconductor LED as pressure; and a plurality of terminals formed on the rigid frame, electrically connected to the first and second conductivity-type cladding layers and the piezoelectric layer, respectively.
