An illumination module, comprising:

• a light source configured to emit an illumination beam;
• a reflective light valve disposed on a path of the illumination beam and comprising a plurality of pixels, wherein each of the pixels is adapted to switch between a first state and a second state, a pixel in the first state among the pixels is configured to reflect the illumination beam into an effective beam, and a pixel in the second state among the pixels is configured to reflect the illumination beam into an auxiliary beam;
• a lens disposed on a path of the effective beam and configured to project the effective beam to an area to be illuminated;
• and
• a diffuser disposed on a path of the auxiliary beam from the reflective light valve and configured to diffuse the auxiliary beam into a diffused light, wherein the lens is also disposed on a path of the diffused light, and is configured to project the diffused light to the area to be illuminated.
