Abstract
A light source system comprises a light source disposed within a non-imaging optical element. The non-imaging optical element does not produce a direct image of the light source, and the output light field at the output surface of the non-imaging optical element has an intensity that is substantially uniform over the area of the output surface. A light source system of the invention is therefore smaller and lighter than a prior art system of the same output power, since there is no need to provide further components, such as an integrator, to homogenise the output light field.
Claims41
A light source system comprising:
- a light source;
- and a non-imaging optical element, the non-imaging optical element having an output surface;
- wherein the light source is disposed within the non-imaging optical element.
A light source system comprising:
- an array of at least first and second light sources;
- and at least first and second non-imaging optical elements, the first and second light sources being disposed within a respective one of the first and second non-imaging optical elements;
- wherein each of the first and second non-imaging optical elements has an output surface;
- and wherein the output surface of the first non-imaging optical element is substantially contiguous with the output surface of the second non-imaging optical element.
