Abstract
Provided is a projection device that prevents glare of light emitted from an auxiliary lamp of a vehicle and suppresses a decrease in brightness of a light pattern projected onto a road surface. A projection device (1) mounted on a vehicle to project a light pattern onto a surrounding road surface includes a far distance side projection unit (2, 3) that projects a predetermined far distance side light pattern onto a relatively far position, and a near distance side projection unit (4) that projects a predetermined near distance side light pattern onto a relatively near position. The far distance side projection unit (2, 3) projects, as a light pattern (FOP, COP), the surface shape of a light emitting surface of an LED (12, 13) by a projection lens (22, 23). The near distance side projection unit (4) projects, as a light pattern (NOP), the opening shape of a shade opening (34) opened in a shade (30) that blocks light emitted from an LED (14), by a projection lens (24).
