Abstract:
A DMD headlamp disposed at a lower end of a low beam headlamp includes: a reflector unit reflecting light emitted from a light source; and a DMD board that includes a digital micromirror unit, a control unit, a power supply unit, and an outside connecting connector disposed on a Printed Circuit Board (PCB), the DMD board being disposed in an area to which light is reflected from the reflector unit to reflect the light to a projection lens, The outside connecting connector is disposed at the lower end of the DMD board so that a distance from a center point of the outside connecting connector to the lower end of the DMD board is smaller than a distance from the center point of the outside connecting connector to the upper end of the DMD board.
