1 Scope

This technical guidance document gives the blue light of all lighting products whose main radiant energy is in the visible light range (380nm~780nm).

Instructions and guidance for light hazard evaluation, through optical and spectral calculations, the photobiological safety measurement described in GB/T 20145 tells us

Product information, and if the product is intended to be a component of a higher-level lighting product, you can get how to use this information from the component (e.g.

LED packages, LED modules, or lamps) are delivered to higher-level lighting products (such as lamps).

Appendix C gives a summary of recommendations that help to consistently apply GB/T 20145 to evaluate the blue light hazards of light sources and luminaires.

Note. It is expected that the safety standards of HID and LED products will refer to this guiding technical document.
