Scope
Scope: This standard specifies the terms and definitions, classification, general requirements, technical requirements, and test methods for educational lighting fixtures. This standard applies to educational lighting fixtures used in classrooms, reading rooms, and laboratories in primary and secondary schools or similar teaching venues. Main technical content: 3.1 Direct lighting: Illumination in which 90% to 100% of the luminous flux is directly projected onto a working surface without a defined boundary, relying on the light intensity distribution characteristics of the luminaire. [GB/T 2900.65-2004, Definition 845-0944] 3.2 Semi-direct lighting: Illumination in which 60% to 90% of the luminous flux is directly projected onto a working surface without a defined boundary, relying on the light intensity distribution characteristics of the luminaire. [GB/T 2900.65-2004, Definition 845-0945] 3.3 General diffused lighting: Illumination in which 40% to 60% of the luminous flux is directly projected onto a working surface without a defined boundary, relying on the light intensity distribution characteristics of the luminaire. [GB/T 2900.65-2004, Definition 845-09-16] 3.4 Semi-indirect lighting: Illumination in which 10% to 40% of the luminous flux is directly projected onto a working surface without a defined boundary, relying on the light intensity distribution characteristics of the luminaire. [GB/T 2900.65-2004, Definition 845-09-17] 3.5 Indirect lighting: Illumination in which 0% to 10% of the luminous flux is directly projected onto a working surface without a defined boundary, relying on the light intensity distribution characteristics of the luminaire. [GB/T 2900.65-2004, Definition 845-0948] 3.6 Input power: The electrical power consumed by the luminaire, including all electrical components necessary for its predefined functions, when operating on the main power supply. [GB/T 31897.1-2015, Definition 3.1]
