  • Patent number: 11543095
    Abstract: 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.

    Abstract: An optical scanning apparatus includes a light source, a substrate, a reflection member, a drive unit, and a controller. A scanning mirror and an attitude detector are integrated with substrate. An attitude detector outputs a first signal according to an attitude angle of substrate. A reflection member reflects a light beam reflected by scanning mirror. A drive unit can adjust an inclination of reflection member with respect to a main surface of substrate. A controller controls drive unit based on first signal. For this reason, an outgoing angle of light beam from optical scanning apparatus with respect to a horizontal surface can stably be maintained regardless of the inclination of optical scanning apparatus with respect to horizontal surface.
