Analyses of optical radiation safety standards for laser illuminated products

Abstract

AbstractThe high energy density of optical radiation from laser illuminated products may cause eye injury, so it is necessary to study the optical radiation safety standards for these products. The relations of related international and Chinese organizations, such as IEC/TC76, IEC/TC108, IEC/TC110, Chinese technical committee SAC/TC284, and so on, are introduced. The related standards and the relations are surveyed, especially the safety of laser products (IEC 60825) series, the photobiological safety of lamps and lamp systems (IEC 62741) series, and audio/video, information and communication technology equipment—part 1: safety requirements (IEC 62368‐1:2018). As application examples of standards, some specific laser illuminated products, including the laser projector, the laser headlamp and light detection and ranging (LiDAR) used in the vehicle, as well as the evaluation methods for the blue light effect of the display are discussed and analyzed. On the basis of the analyses of the optical radiation safety standards, it is necessary to select or develop appropriate standards for different types of laser illuminated products.
