LUMINESCENCE DIODE CHIP WITH AN ANGLE FILTER ELEMENT |
摘要 |
A luminescent diode chip includes a semiconductor body, which produces radiation of a first wavelength. A luminescence conversion element produces radiation of a second wavelength from the radiation of the first wavelength. An angular filter element reflects radiation that impinges on the angular filter element at a specific angle in relation to a main direction of emission back in the direction of the semiconductor body. |
