SOLID STATE LIGHT SOURCE WITH OPTICAL FILTER CONTAINING METAL DERIVATIVES OF TETRAPHENYLPORPHIN |
摘要 |
A solid state light source adapted for viewing in an environment of ambient light. A solid state light-emitting device is provided for emitting a narrow band of visible light. An optical filter is disposed in the path between the light emitting device and the viewer. The filter is a polymeric matrix which contains at least one metal derivative of tetraphenylporphin. In a preferred embodiment of the invention the polymeric matrix is an acrylic ester polymer which overlays the transparent encapsulating surface of a red-emitting GaAsP diode.
