ILLUMINATION SYSTEM, LUMINAIRE, COLLIMATOR, AND DISPLAY DEVICE |
摘要 |
The invention relates to an illumination system (10), a luminaire (102), a collimator (30) and a display device (200). The illumination system according to the invention comprises a light source (20) and the collimator. The light source is configured for emitting a substantially Lambertian light distribution around a symmetry axis (22). The refractive collimator is configured for redirecting light from the light source to at least partially illuminate an illuminating surface (50) in which at least a part of the illuminating surface being substantially parallel to the symmetry axis. The refractive collimator comprises a concave input window (34) and an at least partially convex output window (40) for refracting light towards the illuminating surface. The effect of the illumination system according to the invention is that a height of the illumination system may be reduced due to the use of the refractive collimator. |
