T/GIES 020-2024 Quality grading and "Pioneer" evaluation requirements for LED vertical reading lamps and lamps

Scope

Scope: This document specifies the basic requirements, evaluation indicators, and requirements for LED upright reading and writing lamps, as well as the evaluation methods and grade divisions of their product quality and enterprise standard levels. This document applies to the evaluation of the product quality and enterprise standard levels of LED upright reading and writing lamps with a rated power supply voltage not exceeding 250V. Relevant institutions can refer to this document when conducting quality grading and enterprise standard level evaluations, as well as "leader" product evaluations and related certifications. Enterprises can also refer to this document when formulating their own enterprise standards. Main technical content: Basic indicators: compliance with safety requirements, harmonic current, radio interference characteristics, limits on restricted substances, blue light hazard, light shielding, noise, flicker depth, and related requirements for a 15° tilt. Core indicators: illuminance and illuminance uniformity, general color rendering index, light efficiency, rated lifespan, and glare, which are divided into different levels. Innovative indicators: special color rendering index, plane color deviation, and CQS (light color quality).
