Patent attributes
A polarized light emitting device including a first reflector, an LED chip, a fluorescent layer, a second reflector and a polarizer with corrugation structure is provided. In the polarized light emitting device, the LED chip emits a first light (e.g. ultraviolet light) confined within a resonant chamber configured by the first reflector and the second reflector, therefore the fluorescent layer can be adequately illuminated by the first light, thus emitting more second light (visible light) and improving the electro-optical transforming efficiency. The second reflector is adapted for reflecting the first light, and allows most of the second light to pass through. The polarizer with corrugation structure disposed outside the resonant chamber is adapted for efficiently polarizing the second light.
