Abstract
To generate a projected light beam, a headlamp includes: a light source to provide light; and a digital micromirror device (DMD). Illumination optics are optically coupled between the light source and the DMD to illuminate the DMD with the light from the light source. The DMD is arranged to reflect the light as pixelated light. Projection optics are optically coupled to the DMD to project the pixelated light as a mid-beam portion of the projected light beam. The mid-beam portion has a non-uniform mid-range beam profile shaped by at least the DMD and the illumination optics. A field of view and an intensity of the projected light beam are controllable by the light source and the DMD. Also, the headlamp includes a high beam module to provide a high beam portion of the projected light beam.
