LIGHT EMITTING DEVICE

摘要

PURPOSE: A light emitting device is provided to improve the emitting efficiency of the linear polarization from the depolarized light source by forming a rotary asymmetric encapsulant. CONSTITUTION: Light source emits lights to the one or more directions. An encapsulant includes a shape which modifies the polarization anisotropy of the lights which are emitted from the light source. The encapsulant is composed of a transparent material. The polarization anisotropy of the lights is improved by the encapsulant. The light source is a semiconductor light emitting diode chip.
