Fine ceramics (advanced ceramics, advanced technical ceramics) — Test methods for optical properties of ceramic phosphors for white light emitting diodes using a Goniospectrofluorometer
|Publication Date:||2 June 2020|
|ICS Code (Advanced ceramics):||81.060.30|
This specification applies to ceramic phosphor powders which are used in white light-emitting diodes (LEDs) and emit visible light when excited by UV or blue light and specifies a method for use of a goniospectrofluorome
This specification may also be adopted for phosphors used in non-white LEDs, for example, green, orange, pink, purple, or other coloured LEDs.
