Patent number: 11543095Abstract: A lens holder which supports a projection lens is screwed and fixed to a bracket which supports a spatial light modulator. A positioning pin configured to position the lens holder in a left-right direction with respect to the bracket is inserted into a long hole which is formed in the bracket and extends in a lamp front-rear direction. The screwing and fixing is performed in a state where the positioning pin is inserted into the long hole and is appropriately moved in the lamp front-rear direction, so that the lens holder is restricted from being displaced in a left-right direction with respect to the bracket, and it is possible to finely adjust a positional relationship between the projection lens and the spatial light modulator in the lamp front-rear direction.Type: GrantFiled: April 4, 2019Date of Patent: January 3, 2023Assignee: KOITO MANUFACTURING CO., LTD.Inventors: Ryuho Sato, Yukinobu Hiranaka, Takahiko Honda, Yosuke Ohashi, Takashi Ito
