技術說明

本創作提供一種雷射車燈光學模組，包含光源、凸透鏡、基板、反射鏡組、複數個支撐桿與傳動構件。光源由雷射二極體所組成，以產生雷射光束。凸透鏡位於光源所產生之雷射光束的傳遞路徑上以聚焦雷射光束。基板位於該透鏡聚焦雷射光束後的傳遞路徑上，且在該基板上塗佈黃螢光粉。反射鏡組設置於該基板所反射之該雷射光束的傳遞路徑上。支撐桿設置於該反射鏡組的後側，且用於支撐反射鏡組。傳動構件設置於反射鏡組的後側並連接支撐桿，透過傳動構件帶動支撐桿改變反射鏡組的光反射面，進而改變雷射車燈光學模組的光場。 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.
