Abstract
The invention provides a high quality composite phosphor powder which ensures diversity in emission spectrum, color reproduction index, color temperature and color, a light emitting device using the same and a method for manufacturing the composite phosphor powder. The composite phosphor powder comprises composite particles. Each of the composite particles includes at least two types of phosphor particles and a light transmitting binder. The phosphor particles have different emission spectrums. In addition, the light transmitting binder is formed between the phosphor particles and binds them together.
