POLARIZATION LED MODULE, AND LIGHTING DEVICE AND PROJECTOR HAVING THE SAME |
| 摘要 |
Provided is a polarization light emitting diode (LED) module including: a casing comprising an opening; a light source configured to emit light; a reflective polarizer configured to transmit first polarized light of the light emitted from the light source through the opening of the casing toward an external polarization converter, and configured to reflect second polarized light of the light emitted from the light source toward the light source; and a reflector configured to reflect light, which is reflected from the reflective polarizer and traveling toward the light source, toward the reflective polarizer, wherein the light source, the reflective polarizer and the reflector are provided inside the casing. |
