Polarized light emitting diode device and method for manufacturing the same

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.

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 polarization layer, a reflection layer and a conversion layer while enabling the three layers along with the LED chip to enclose a space to be used as a light transmitting layer configured with a first side and a second side that are arranged opposite to each other;
• enabling the polarization layer and the reflection layer to be arranged respectively on the first side and the second side of the light transmitting layer while configuring the light transmitting layer with a light entering surface and a second light emitting surface in a manner that light entering surface and the second light emitting surface are arranged opposite to each other and are sandwiched between the polarization layer and the reflection layer as well as the second light emitting surface is provided for the conversion layer to be disposed thereon;
• and
• using a packaging material for packaging the polarization layer, the reflection layer, the LED chip and the base into a package while enabling the light entering surface of the light transmitting layer 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 light transmitting layer 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.
