Abstract
In described examples of an automotive headlamp, a first illumination source outputs a first color light, and a second illumination source outputs a second color light different from the first color light. A digital micromirror device receives the first color light and the second color light and reflects the first color light and the second color light. A projection optics receives reflected light from the digital micromirror device and outputs a beam from the automotive headlamp having a color that is a combination of the first and second colors. A controller controls intensity and duration of the first illumination source and the second illumination source, controls a pattern on the digital micromirror device, and spectrally tunes the color of the output beam.
