Image projector having a LED light source

An image projector having a light emitting diode (LED) light source, comprising:

• an optical engine comprising:
• a light emitting diode (LED) for producing the light;
• a Digital Micromirror Device (DMD) for receiving the light from the optical engine, and refracting the image;
• and
• a projection lens set, for focusing the image and forming on an external projection surface;
• a printed circuit board (PCB) module connected to the optical engine to control the projection of the optical engine, the PCB module comprising:
• a first PCB;
• a second PCB which is set-up in parallel to the first PCB;
• at least one connecting interface for connecting an exterior device;
• and
• a control unit, coupled to the at least one connecting interface, for processing image data received from the at least one connecting interface and transferring the processed image data to the optical engine;
• a heat sink module for dissipating the heat generated by the optical engine and the PCB module, the heat sink module comprising a heat dissipating fan, an entrance airway, and an exit airway, which build into a heat dissipating route that starts from the entrance airway then passes through the heat dissipating fan and then ends at the exit airway;
• a operation interface module, coupled to the PCB module, for controlling the operation of the image projector;
• and
• a supporting frame utilized to contain and position the optical engine, PCB module, heat-dissipating module and operation interface module.
