Note 2: Rewrite from JGJ/T 119-2008, definition 2.3.28. 3.5 Unified glare rating UGR It is a psychological parameter, that measures the subjective reaction of discomfort caused by light emitted by lighting devices in an indoor visual environment to the human eye. Its value can be calculated according to the unified glare rating formula of the International Commission on Illuminance (CIE). Note: Rewrite from JGJ/T 119-2008, definition 2.2.25. 3.6 Lighting power density LPD The actual power consumed by lighting per unit area (including light sources, ballasts or transformers, etc.), in watts per square meter (W/m2). 3.7 Maintained average illuminance The average illuminance on the specified surface shall not be lower than this value. It is the average illuminance on a specified surface at the time when the lighting device must be maintained. Note: Rewrite from JGJ/T 119-2008, definition 3.2.8. 3.8 Uniformity ratio of luminance The ratio of minimum illuminance to average illuminance on a specified surface. Note: Rewrite from JGJ/T 119-2008, definition 3.2.10. 3.9 Direct glare Glare produced by luminous objects in the field of vision, especially close to the line of sight.4 Hygienic requirements for classroom desktop andblackboard illuminance 4.1 The maintained average illuminance of classroom desktop is not less than 300 lx; the uniformity ratio of luminance is not less than 0.7. 4.2 The maintained average illuminance of classroom blackboard is not less than 500 lx; the uniformity ratio of luminance is not less than 0.8. 4.3 The classroom lighting measurement method shall be implemented in accordance with GB/T 5700.5 Hygienic requirements for classroom lighting design andinstallation 5.1 Luminaires 5.1.1 It shall comply with the requirements of GB 7000.1, GB 7000.201, GB/T 17743. 5.1.2 Suspended grille luminaires should be used; the luminaire efficiency shall not be less than 60%. 5.1.3 The unified glare rating (UGR) should not be greater than 19. The calculation method of the unified glare rating (UGR) is implemented in accordance with CIE 117. 5.2 Ballast Electronic ballasts shall be used. 5.3 Light source It should use narrow tube-shaped rare earth three-primary color fluorescent luminaires, which have a color temperature of 3300 K ~ 5300 K, a color rendering index of not less than 80, less than 26 mm. It should be replaced uniformly according to the design life of the light source. 5.4 Installation Use the hanging rod installation method and distribute it evenly in the longitudinal direction of the classroom (the long axis of the luminaires is perpendicular to the blackboard). The lighting power density of the classroom shall not be higher than 11 W/m2; it should be lower than 9 W/m2 in areas where conditions permit. The vertical distance (g) between the luminaire and the desk shall not be less than 1700 mm, see Figure 1. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
