Scope

Scope:1 Scope This document refers to the indoor environment of kindergartens, including nurseries, kindergarten activity rooms, multi-functional rooms, study rooms, bedrooms, washrooms, morning check-up rooms, health observation rooms, etc. Similar venues such as childcare and education facilities can refer to this document. This document specifies the basic requirements for indoor environmental lighting in kindergartens, technical requirements for lighting environment (maintaining average illuminance, illuminance uniformity, unified glare value, color rendering index, illuminance near the work surface, color temperature, power density, fluctuation depth, photobiological safety, blue light, etc.), and control system requirements. This document applies to new, renovated, and expanded indoor lighting projects of kindergartens and nurseries in Jiangsu Province. Main technical content: (Light) Illuminance: The illuminance at a point on the surface is the ratio of the luminous flux incident on the surface element containing the point to the area of the surface element, i.e.: () where: —— The luminous flux propagated by the beam element at the specified point within the solid angle containing the specified direction, unit: lumens (lm); —— The cross-sectional area of the beam containing the specified point, unit: square meters (m2). Initial Average Illuminance: The average illuminance on the specified surface when the lighting fixture is newly installed. Maintained Average Illuminance: The average illuminance on the specified surface when the lighting fixture requires maintenance. It is calculated by multiplying the initial average illuminance by the maintenance coefficient. Maintenance Coefficient: The ratio of the average illuminance on the specified surface after a certain period of use to the average illuminance obtained when the device is newly installed under the same conditions. Illuminance Uniformity Ratio: The ratio of the minimum illuminance to
