A miniature projector module includes: a light source unit capable of emitting source light with first and second polarizations; a polarization beam splitter capable of reflecting the source light with the first polarization, and permitting transmission of the source light with the second polarization therethrough; a first image modulator capable of converting the source light with the first polarization reflected by the beam splitter into image light with the second polarization, and directing the image light with the second polarization toward the beam splitter for further transmission therethrough; a second image modulator capable of converting the source light with the second polarization transmitted through the beam splitter into image light with the first polarization, and directing the image light with the first polarization toward the beam splitter for further reflection thereby; and a projector lens for receiving and projecting the image light from the beam splitter.

Miniature projector module having effective utilization of light with two polarizations

A light assembly includes a heat-dissipating device, a light-emitting device, and a reflector. The heat-dissipating device defines an accommodating space. The light-emitting device is disposed in the accommodating space. The reflector serves to reflect light emitted by the light-emitting device, extends into the accommodating space, and surrounds the light-emitting device.
