Abstract
An illumination module includes a light source, a reflective light valve, a lens, and a diffuser. The light source is configured to emit an illumination beam. The reflective light valve is disposed on a path of the illumination beam, and includes multiple pixels. A pixel in a first state among the pixels is configured to reflect the illumination beam into an effective beam. A pixel in a second state among the pixels is configured to reflect the illumination beam into an auxiliary beam. The lens is disposed on a path of the effective beam, and configured to project the effective beam to an area to be illuminated. The diffuser is configured to diffuse the auxiliary beam from the reflective light valve into a diffused light. The lens is configured to project the diffused light to the area to be illuminated.
