A laser headlight optical module is disclosed herein and comprises a laser light source, a convex lens, a substrate, a mirror set, supporting rods, and a driving member. The laser light source generates a laser light and the convex lens is located at a transmitting path of the laser light generated from the laser light source and configured to focus the laser light. Yellow fluorescent powders are coated on the substrate. The mirror set is located at a transmitting path of the laser light reflected from the substrate with the phosphor layer. The supporting rods are located behind the mirror set to support the mirror set. The driving member is located behind the mirror set and connected with the supporting rods. The driving member drives the supporting rods to change a light reflective surface of the mirror set to vary an optical field.

Laser headlight system and laser headlight optical module thereof

A light-mixing flashlight has a body, three light-emitting diodes, three first reflectors, and three second reflectors. The body has a mounting surface formed in the body, a body opening opposite to the mounting surface, and three light recesses formed in an interior of the body. The light-emitting diodes are mounted in the light recesses, and are respectively a red light, a green light, and a blue light light-emitting diode. The first reflectors are formed as parabolic mirrors and are respectively mounted in the light recesses via a working angle. An opening of each first reflector faces toward the corresponding light-emitting diode. The second reflectors are formed as spherical mirrors, are mounted on the mounting surface, and respectively correspond in position to the first reflectors. Therefore, the light-mixing flashlight has an improved emitting efficiency.
