Scope
Scope: This document specifies the grading and evaluation requirements for LED reading and writing desk lamps (hereinafter referred to as "desk lamps"). Main technical content: The standard is divided into five chapters, including "Scope", "Normative References", "Terms and Definitions", "Technical Requirements", and "Test Methods". (1) Scope This standard specifies the grading and evaluation requirements for LED reading and writing desk lamps. (2) Normative References The standard primarily includes safety standards GB 7000.1 "Luminaires - Part 1: General Requirements and Tests" and GB 7000.204 "Luminaires - Parts 2-4: Special Requirements for Portable General Purpose Luminaires". Definitions and numerical requirements for various basic lighting indicators are referenced from GB/T 9473-2017 "Performance Requirements for Reading and Writing Desk Lamps". Standards for human electromagnetic radiation are referenced from GB/T 31275 "Evaluation of Electromagnetic Radiation from Lighting Equipment to Humans". Blue light hazard and flicker are assessed using international standards IEC/TR 62778:2014 "Evaluation of Blue Light Hazard from Light Sources and Luminaires Using IEC 62471" and IEEE Std 1789-2015 "IEEE Recommended Methods for Modulating Current in High-Intensity LEDs to Mitigate Health Risks to Users". New requirements for power and colorimetric deviation are adopted from GB/T 31897.201-2016 "Luminaire Performance - Part 2-1: Special Requirements for LED Luminaires". The calculation method for colorimetric deviation of non-standard target color temperatures references ANSI C78.377-2017 "Colorimetric Specifications for Solid-State Lighting Products". (3) Terms and Definitions New definitions are added for LED reading and writing desk lamps and "fluctuation depth". (4) Technical Requirements The quality of reading and writing desk lamps that meet acceptance criteria is graded and evaluated into three levels (Level 1 being the highest). In ad
