Abstract: A laser module package with dual colors and multi-dies mainly includes a first PCB arranged in long shape and electrically connected to a plurality of first dies, a second PCB arranged in long shape and electrically connected to a plurality of second dies, a plurality of first collimators correspondingly disposed in a plurality of first openings, and a plurality of second collimators correspondingly disposed in a plurality of second openings. A plurality of first reflectors correspondingly reflects laser beams emitted from the first dies to the first collimators and a plurality of second reflectors correspondingly reflects laser beams emitted from the second dies to the second collimators; or having a plurality of first metal pieces fixing corresponding first dies for the laser beams emitted therefrom to go through the corresponding first collimators and a plurality of second metal pieces fixing corresponding second dies for the laser beams emitted therefrom to go through the corresponding second collimators.

Abstract: A dot projector with automatic power control includes a housing covering a substrate with an installing space and a platform therein, an automatic power control integrated circuit, a photodiode and a reflector disposed under the platform of the housing, a collimator disposed in the installing space of the housing and a diffractive optical element bonded on the platform of the housing. Whereby a laser diode emits a laser light to the reflector for the laser light to be reflected perpendicularly through the collimator to the diffractive optical element; then the diffractive optical element produces a plurality of light spots and the a stray light is also produced from the laser light. The photodiode of the automatic power control integrated circuit then detects the stray light and produces a feedback signal transmitted back to the laser diode for adjustment of the laser emission power in order to control the light spots produced by the diffractive optical element.
