Abstract:
1. A method for manufacturing a polarized light emitting diode device, comprising the steps of: mounting an LED chip on a base while allowing the same to emit a beam out from a first light emitting surface thereof; constructing a light transmitting layer with a first side and a second side that are arranged opposite to each other; forming a polarization layer on the first side of the light transmitting layer while forming a reflection layer on the second side of the light transmitting layer; cutting the light transmitting layer having the polarization layer and the reflection layer formed thereon so as to form at least one semi-finished product of a polarizing waveguide, whereas each polarizing waveguide semi-finished product is composed of: the polarization layer formed on one side thereof; the reflection layer formed on another side opposite to the one formed with the polarization layer; a light entering surface and a second light emitting surface, in a manner that light entering surface and the second light emitting surface are sandwiched between the polarization layer and the reflection layer; disposing a conversion layer on the second light emitting surface of each polarizing waveguide semi-finished product so as to construct a polarizing waveguide; and using a packaging material for packaging the polarizing waveguide, the LED chip and the base into a package while enabling the light entering surface to face toward the first light emitting surface, and thus enabling the beam emitted from the first light emitting surface of the LED chip to enter the polarizing waveguide through the light entering surface and thereafter project on the polarization layer for reflecting a portion of the beam toward the reflection layer where the reflected portion of the beam is further being reflected to the second light emitting surface so as to be converted by the conversion layer before being projected out of the polarizing waveguide.
