LIGHT BEAM PROJECTION DEVICE HAVING SUBMATRIX OF LIGHT SOURCE, AND ILLUMINATION AND HEAD LIGHT MODULE HAVING THE SAME

摘要

SOLUTION: An optical projection module 1 for an automobile includes at least two associated sets of submatrices 20 provided with a main light source located on the upstream side with respect to a light beam propagation direction, each of them being capable of emitting the light beam, and a main optical system 4 located on the downstream side and provided with a plurality of converging optical parts. At least one converging optical part is associated with each submatrix and is arranged on the downstream side of each submatrix. A separation interval between optical axes of two adjacent converging optical parts corresponds to a separation interval between the centers of the corresponding adjacent submatrices respectively.;EFFECT: Manufacturing costs are reduced, and damage can be reduced in the event of breakage. Favorable uniformity in light distribution among submatrices is provided, and favorable uniformity in light distribution among light sources constituting submatrices is provided in the submatrix as well.;SELECTED DRAWING: Figure 5;COPYRIGHT: (C)2017,JPO&INPIT
