Ambient lighting for an image projector

A system comprises means (PL; MI) for projecting an image light beam (ILB) on a projection area (PA) for display of an image (PI) on the projection area (PA), and means (1) for generating an ambient light beam (ALB; ALB1, ALB2) and comprising: an ambient light source (LS; LS1, LS2) for generating ambient light, a collimator (CO) or a light-guide (LG1, LG2) for receiving the ambient light to supply the ambient light beam (ALB; ALB1, ALB2), and a reflector (RF; RF1, RF2) for reflecting the ambient light beam (ALB; ALB1, ALB2) towards the projection area (PA) to obtain an ambient lighting area (ALI) adjacent the image (PI).
