Production of a collimated beam

To produce a collimated beam of light for illuminating displays, there is provided a highly reflective diffusely illuminated cavity source 11 having apertures or holes 12 in one wall . Each aperture 12 has a finite depth and angled sides tapering outwardly. The apertures allow light to pass directly through over a limited range of angles but light which enters the apertures at larger angles is reflected off the walls of the apertures. Any radiation not entering an aperture is reflected back into the cavity and then reflected by another wall of the cavity and thus has a finite probability of entering one of the apertures. In this way the a high proportion of the light coming into the cavity will exit the cavity in a preferred direction. The collimation can be improved by placing a lens or diffractive hologram placed after the tapered apertures.

In addition, when light is incident at an angle at least equal to the prescribed angle relative to the normal line, the transparent prism (30) emits the light toward an indoor ceiling side using at least two types of optical path having different numbers of reflections, using reflection at at least one of the transparent prism (30) surface and the reflecting member (40), and when light is incident at an angle less than the prescribed angle, the transparent prism allows the light to be transmitted through the third edge (30c).
