Led-based white-emitting illumination unit |
摘要 |
A white-emitting luminescence conversion LED uses a chlorosilicate phosphor which, in addition to Ca and Mg, contains a europium doping, and also a garnet phosphor of the rare earths, in particular Y and/or Tb. In this way, it is possible to achieve a high color rendering and a high constancy of the lighting properties under differing temperature conditions.
