ABSTRACT:
An image projector having a LED light source comprises: an optical engine using the LED as the light source, a PCB module, a heat sink module and a main frame. The printed circuit board (PCB) module further comprises: a first circuit board, a second circuit board, at least one I/O interface for connecting an external device, at least one card reader for connecting an external memory card, and a control unit for processing the image data received from the I/O interface or card reader and projecting the image by using the optical engine. The first circuit board and second circuit board are furnished in an overlap and parallel manner to decrease the space consumption. The heat sink module comprises a fan, an air inlet and an air outlet, which substantially forms a heat dissipating passage from the air inlet through the fan toward the air outlet. The LED and control unit are located in the heat dissipating passage for increasing better heat dissipation effect.
