Abstract
A light distributor includes a panel (202) having a textured surface (206) and a light distribution surface. A number of LEDs (204) are located in proximity to the textured surface. Some of the light (208, 212) impinging on the textured surface (206) is refracted or reflected (214, 216) into the panel (202) from where it can be transmitted through the distribution surface.
Claims9
A lighting device comprising:
- a light distributor member comprising a first collector surface for receiving light and a second surface for distributing the light, wherein the first collector surface includes a textured surface having finely spaced roughened texturing formed in the light distributor member such that the textured surface is roughened to capture incident light received below a critical angle and at least part of the incident light received beyond the critical angle,
- a reflector;
- a light source;
- and
- wherein the first collector surface is facing the reflector, and wherein the light distributor member, the reflector and the light source are arranged so that at least part of the light from the light source which does not impinge directly on the first collector surface is reflected by the reflector to impinge on the textured surface.
