T/GIES 001-2021 "Leader standard" evaluation requirements for LED reading and writing work lamps
Basic Information
Scope
Scope: This document specifies the terminology and definitions, evaluation index system, and evaluation methods for the "Leader" standard evaluation requirements of LED reading and writing desk lamps. This document applies to LED-based reading and writing desk lamps with a rated power supply voltage not exceeding 36V DC or 250V AC, and a frequency of 50Hz. It can be used as a reference for relevant institutions when formulating enterprise standard evaluation programs for "Leader" standards, and by enterprises when developing their own enterprise standards. Main Technical Content: 1. Key Content of the Standard: This document specifies the terminology and definitions, evaluation index system, and evaluation methods for the "Leader" standard evaluation requirements of LED reading and writing desk lamps. It applies to LED-based reading and writing desk lamps with a rated power supply voltage not exceeding 36V DC or 250V AC, and a frequency of 50Hz. It can be used as a reference for relevant institutions when formulating enterprise standard evaluation programs for "Leader" standards, and by enterprises when developing their own enterprise standards. The evaluation indicators of the LED reading and writing desk lamp "Leader" standard include basic indicators, core indicators, and innovative indicators. Basic indicators include: safety requirements, harmonic current, radio interference characteristics, limits on restricted substances, blue light hazard, light shielding, noise, and ripple depth; core indicators include: illuminance and illuminance uniformity, general color rendering index, light efficiency, and rated lifetime; innovative indicators include: special color rendering index, flat color difference, and intelligent level. The evaluation grades of LED reading and writing desk lamp technical indicators are divided into three levels, with level three being the minimum requirement. Levels one, two, and three represent products on the ranking list, with products me
