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.

Vehicle lamp with particular attachment of spatial light modulator to heat sink

A vehicle head lamp which includes: a lamp body having a front side being opened; a lens mounted on the front side of the lamp body; a discharging lamp; a reflector being disposed within a space defined by the lamp body and the lens while supporting the discharging lamp, the reflector being tiltable with respect to the lamp body; a discharging lamp unit supplying a discharging voltage to the discharging lamp; and a connecting member. The connecting member includes, a plural number of connection cords connecting the discharging lamp and the discharging lamp unit, wherein one of the connection cords is a high voltage cord to which a high voltage is applied, a protecting tube covering the high voltage cord, and a cylindrical member being conductive and flexible wherein the cylindrical member covers the protecting tube as well as covers connection cords which are not covered with the protecting tube.
