Therefore, the light control member 33 can increase the proportion of reflected light 35 , Concentrating the light, that is, reducing the invalid diffusion ratio.

Eliminating direct light 34 reduces unnecessary light, in other words, also reduces the ratio of ineffective diffusion. On the other hand, because the light control member 33 is extended and expanded, the light source cannot be viewed directly at many viewing angles, and has anti-glare effect.

Referring to FIG. 8B, in other embodiments, the light control member 33 has a part of a gap so that the direct light can pass out. For example, the light control member 33 has a one-third part of the gap. This notch is used to illuminate the projector at a short distance. For example, in the case of long-range projection, the brightness of the lower edge near the projector can be maintained for near-end or other lighting purposes.
