Title: HIGH RESOLUTION AUTOMOBILE HEADLIGHT OPTICAL MODULE AND HIGH RESOLUTION HIGH BEAM ILLUMINATION CONTROL METHOD THEREFOR
Abstract:
A high resolution automobile headlight optical module and a high resolution high beam illumination control method therefor. The high resolution automobile headlight optical module comprises: a laser source array (1) and a collimation lens group (3) provided therein, a converging lens group (7), a fluorescent ceramic (6), and a projection lens group (4). An electric control deflection reflective mirror unit (5) is provided in front of the light exit direction of a laser beam combining lens group (2). Reflecting surfaces of a reflective mirror form a segment which scans in a reciprocating manner in a high-speed reciprocating shaft winding swing within a specified rotating angle range. A transmission type fluorescent ceramic converts a blue single wavelength light illuminated on the front side of the fluorescent ceramic into a while composite wavelength light for outputting on the back of the fluorescent ceramic. A dark space formed by a high resolution automobile headlight can reach the size of the head when an opposite driver is positioned at different positions, and other spaces still keep high-brightness illumination when a target does not exist completely so that the dazzling of the opposite driver can be avoided.
