Abstract

A light source projection device includes a light emitting diode array, a collimating device, a light adjusting lens and an image generating portion. The light emitting diode array can emit at least a light beam. The collimating device is installed at the light-emitting side of the light-emitting diode array and can receive at least a light beam and collimate and transform the light beam into at least a parallel light beam. The light adjusting lens is installed adjacent to the light-emitting face of the collimating device and can receive at least a parallel light beam and adjust and transform the parallel light beam into at least a geometric light beam. The image generating portion can receive at least a geometric light beam and transform it into image.
