Introduction

This standard is in accordance with GB 7247.1-2012 (IEC 60825-1.2007, IDT) and GB/T 20145-2006 (CIES009/E. 2002, IDT) established the principle of safe classification of optical radiation for laser and incoherent light, citing IEC 60825-1.2014 and GB/T 30117.5- The latest technical content in.2019. GB/T 7247 "Safety of Laser Products" (all parts) is developed using IEC 60825 "Safety of Laser Products" (all parts). Among them, GB 7247.1-2012 (IEC 60825-1.2007, IDT) is the basic standard of this series of standards, which stipulates the general purpose of laser products. Light security level classification requirements. The other parts specify specific laser safety requirements based on different products and applications. GB/T 20145-2006 (CIES009/E.2002, IDT) specifies the classification and general requirements for incoherent optical radiation safety levels. CIES009/E.2002 is prepared by CIE and processed by IEC /TC76 to form IEC 62471. International Electrotechnical Commission to IEC 62471 As a basic standard, it has developed into a series of non-coherent optical radiation safety standards for different incoherent light source products and applications. The first of them Part 5 is converted to GB/T 30117.5-2019 (IEC 62471-5.2015, IDT), which specifies the safety of optical radiation for incoherent light projectors. Claim. Household laser display system optical radiation safety characteristics Evaluation requirements

1 Scope

This standard specifies the optical radiation safety requirements of household laser display systems (hereinafter referred to as systems), including optical radiation safety classification requirements, system Manufacturer requirements, use and maintenance requirements. This standard is applicable to lasers, incoherent lights and spectral ranges from 380 nm to 780 nm for household ultra-short-focus laser display systems. Evaluation of optical radiation safety characteristics of laser and incoherent light hybrid sources. The evaluation of the optical radiation safety characteristics of fluorescent light sources can refer to this standard. carried out. This standard does not apply to the evaluation of optical radiation safety characteristics of laser scanning display systems.
