Abstract
The invention relates to a double-row matrix illumination module, wherein a light source part comprises an LED circuit board and a heat sink that are secured to each other; a primary optical system comprises a primary optical element mounting bracket, a primary optical element press plate and an LED circuit board. Primary optical elements are all mounted on the primary optical element mounting bracket in position. The primary optical elements are consisted of two layers, wherein the upper layer is primary optical element A and the lower layer is primary optical element B. The primary optical element mounting bracket configured as a base component for mounting and positioning comprises two rows of rectangular holes for fixing light-incident ends of the primary optical element A and the primary optical element B respectively and separating the light-incident ends from each other. The invention can realize anti-dazzling high beam function, low beam follow-up steering function, high beam follow-up steering; regarded as a whole, the follow-up steering function can be realized for the high beam and the low beam, thereby improving illumination experience when steering. Structurally, the i…
