发明名称 Vehicle lamp including image forming device and method for controlling the same
摘要 A vehicle lamp that can form a light distribution pattern required therefor effectively even with the existing DMD is provided. A vehicle lamp 1 includes a projection lens 6, a two-dimensional image forming device 10, 30 including a projection surface 11 positioned near a rear focal point F of the projection lens, and a light source 4 configured to irradiate the two-dimensional image forming device 10 with light, wherein the projection surface 11 is formed by a plurality of optical elements 12 that can be driven independently of the others, in the projection surface 11, illumination patterns 14a, 14b can be formed simultaneously and individually on a plurality of projection areas 13a, 13b, and the plurality of illumination patterns 14a, 14b are projected to the front of the lamp by the projection lens 6 so as to form a single or a plurality of light distribution patterns 20.

主权项 1. A vehicle lamp comprising: a projection lens; a two-dimensional image forming device including a projection surface positioned near a rear focal point of the projection lens; and a light source configured to irradiate the two-dimensional image forming device with light, wherein: the projection surface comprising a plurality of optical elements arranged into a matrix on a single substrate, the plurality of optical elements being driven independently from one another, in the projection surface, a first illumination pattern and a second illumination pattern formed simultaneously and individually on a first projection area and a second projection area, respectively, the first projection area and the second projection area arranged along a first direction, and the first and the second illumination patterns are projected to the front of the lamp by the projection lens so as to be re-arranged along a second direction different from the first direction, and wherein the first and the second illumination patterns are projected so as to partially overlap each other by the projection lens to form the single light distribution pattern.
