Abstract: The present application reveals a light projection device, in which part of beam is projected from a light source module to a digital micromirror device. A light expansion module above the digital micromirror device receives part of the beam reflected from the digital micromirror device for projection. A light projection range of the light projection device is larger than a light projection range of the digital micromirror device. When part of the beam is projected from the light source module to both sides of the digital micromirror device, part of the beam is projected to the light expansion modules disposed on both sides of the digital micromirror device for reflection, and hence making light be used effectively and providing a lighting device with a wide angle of lighting.

Abstract: The present invention provides a light projection structure, in which an auxiliary lamp device is disposed on one side of a main lamp device. The main lamp device projects a first light pattern and the auxiliary lamp device projects a second light pattern. The second light pattern includes a gap. The first light pattern projected by the main lamp device is projected onto the gap, so that the main lamp device and the auxiliary lamp device combined can broaden the light projection range, and hence producing more uniform light patterns as well as increasing the light illumination area.

Abstract: The present invention provides a light source module. The first light source forms the first beam from the second light source, the third light source, and the function of the first beam splitter. Then the second beam splitter reflects the first beam and transmits the fourth beam from the fourth light source for forming the mixed beam, which is received and projected by the optical processing device. Thereby, by using the high color rendering and special optical properties of the mixed beam, the applications and efficacy of the present invention can be improved.

Abstract: A lamp comprises a base, at least one light source arranged on the base, a cover positioned on the base and covering the light source, and a structured film arranged adjacent to the light source. The structured film has at least one micro structure configured for guiding part of the light backward emitted from the light source.
