Recently, the General Administration of Quality Supervision, National Standards Committee of the People's Republic of China approved the issuance of the "National Standard for Optical Radiation Safety Testing Methods for Semiconductor Lighting Equipment and Systems". The standard, based on the light environment constructed by lighting equipment and systems, aiming at the actual use of lighting environment, proposed the safety classification, measurement and evaluation methods of the light radiation in the field lighting environment.

With the rapid development of its technology, LED has been widely used in general lighting and display fields. However, due to the inconsistency and disharmony of human biological characteristics, such as the harm of blue light, modern lighting sources such as LED have posed a new threat to human health. The visual health of lighting products has gradually become the focus of current people’s concern.

The introduction of this standard provides a design basis for the planning of the lighting environment, a test basis for the on-site measurement and evaluation of the light radiation safety of the lighting environment, a data basis for the acceptance and rectification of the lighting project and a safety guaranty for users to use LED safely.
