Title:
MATRIX TYPE ILLUMINATION DEVICE FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2019/205900
Kind Code:
A1
Abstract:
A matrix type illumination device for a vehicle, comprising a light source module (2), a projection lens (3), a projection outgoing space (4), and a projection image surface (5) which are sequentially arranged in the direction of an optical axis (1). The light source module (2) comprises a light source array unit (21), a light blocking rib array unit (22), and a light collecting lens array unit (23) which are sequentially arranged in the direction of the optical axis (1). The light source array unit (22) comprises a plurality of light emitting light sources (211) which are independently controlled and arranged in a matrix, and the light blocking rib array unit (22) comprises a plurality of light blocking ribs (221) which are arranged in a matrix and disposed on the peripheries of the light emitting light sources (211). The light collecting lens array unit (23) comprises a plurality of light collecting lenses (231) which are arranged in a matrix and directly face the light emitting light sources (211) in the direction of the optical axis (1). Independent control of the multiple light emitting light sources in the light source module (2) can avoid dazzling causing danger to other participants on the road, and ensure the safety of night driving in all directions on the road. The size of the light source module can be effectively reduced, so that the matrix type illumination device for a vehicle is overall miniaturized.
