- Scope
- This standard specifies the requirements, test methods, inspection rules and marking, packaging, transportation and storage of rare earth yellow phosphors for white LED lamps. This standard is applicable to the phosphor powder of aluminate and related systems prepared by high temperature reaction. The phosphor emits yellow light under the excitation of 440nm~480nm blue light, and the yellow light and the blue light of the excitation source form white light. It is mainly used for blue LED chips. Excited white LED lights.
