ABSTRACT:
A heat radiation structure for a portable micro projector that enables efficient radiation of heat generated therein. A projector module irradiates light of high intensity using a lamp to project an image to an external screen. A thermally conductive plate having a plate-like shape, the projector module being attached to one surface of the thermally conductive plate to transfer heat generated in the projector module. A heat radiation case to which the thermally conductive plate to which the projector module is attached is coupled therein to emit the heat transferred through the thermally conductive plate outside.
