FLUORESCENT VOLUME LIGHT SOURCE WITH REFLECTOR |
摘要 |
An embodiment of the invention is an illumination system including a source of incoherent light capable of generating light in a first wavelength range and an elongate body that emits light in a second wavelength range when illuminated by light in the first wavelength range. The body has a length dimension, a width dimension and a height dimension. At least a portion of the body is tapered so as to increase in width and/or height along the length dimension. The body further includes an extraction surface. A first non-extraction surface extends along at least a portion of the length of the body and is disposed so as to share a common edge with the extraction surface. At least some of the light at the second wavelength is totally internally reflected at the non-extraction surface. At least one external reflector is disposed proximate to the non-extraction surface so as to create a gap between the external reflector and the non-extraction surface.
