This standard includes 7 chapters and 2 appendixes with the main contents as follows. general, terms and definitions, basic requirements, lighting quality and quantity, lighting standard value, lighting energy conservation and lighting distribution and control etc. The main technical contents revised in this standard are. the lighting power density limit specified in former standard is modified; the lighting power density limit for public buildings such as library, reading, exhibition, traffic and finance is supplemented; the service range of incandescent lamp is more strictly restricted; the technical requirements for the light emitting diode lamp applicable to indoor lighting is added; The lighting standard value for areas such as science and technology hall, gallery, financial building, dormitory, senior housing and apartment is supplemented; the control technology requirements for lighting energy conservation is supplemented and improved; the method and scope for the glare assessment is supplemented and improved and the name of public building is specified and unified. The provisions printed in bold type in this standard are compulsory and must be enforced strictly. Ministry of Housing and Urban-Rural Development is in charge of the administration of this standard and the explanation of the compulsory provisions; China Academy of Building Research is responsible for the explanation of specific technical contents.

As for photopicvision. Ф=Km )( d e V(λ)dλ (2.0.3) Where, dФe(λ)/dλ - the spectrum distribution of radiation flux; V(λ) - the spectrum (view) efficiency; Km - the maximum of radiant spectrum (view) efficiency, lm/W. Under photopicvision condition, Km=683 lm/W (λ=555nm). 2.0.4 Luminous intensity The luminous intensity of luminophor in assigned direction is the quotient of the luminous flux dФ transmitted within the solid angle element (dΩ) in this direction divided by such solid angle element, namely the luminous flux of unit solid angle, cd, 1cd=1lm/sr. 2.0.5 Luminance Calculated according to L=d2Ф/(dA·cosθ·dΩ), cd/m2. Where, dФ- the luminous flux transmitting from the light beam element of assigned point, including those within the solid angle (dΩ) in assigned direction, lm; dA- the sectional area of beam (including assigned point), m2; θ- the included angle between normal line of beam section and beam direction. 2.0.6 Illuminance The quotient of luminous flux (dФ) shooting on the surface element containing this point divided by the area of this surface element, lx, 1lx=1lm/m2. 2.0.7 Average illuminance The average illuminance value of all points on the specified surface. 2.0.8 Maintained average illuminance The average illuminance on the specified surface where the lighting device must be maintained. 2.0.9 Reference surface The surface for measuring or specifying the illuminance. 2.0.10 Working plane The plane for conducting work on its surface. The luminous intensity value of light source or light fixture in each direction of space represented by curve or table, it is also referred to light distribution. 2.0.29 Luminous efficacy of a light source The quotient of luminous flux generated by light source divided by light source power, hereinafter referred to as efficacy of light source, lm/W. 2.0.30 Luminaire efficiency The ratio of total light flux emitted by the luminaire to those emitted by all light sources in the luminaire under specified service conditions, which is also named as the light output ratio of luminaire. 2.0.31 Luminaire efficacy The ratio of total light flux emitted by luminaire to input power under specified service conditions, lm/W. 2.0.32 Uniformity ratio of illuminance The ratio of minimum illuminance to average illuminance on the specified surface, U0. 2.0.33 Glare The comfortless sense or diminished capacity to observe detail or target due to unsuitable luminance distribution or range in the view or in the presence of the violent contrast. 2.0.34 Direct glare The glare particularly generated by luminophor close to sight line direction in the view. 2.0.35 Discomfort glare The glare which may generate discomfort but will not reduce the visibility of visual object. 2.0.36 Unified glare rating(UGR) The psychological rating of human eye discomfort subjective response caused by the light emitted from lighting device of indoor visual environment, which is measured by CIE (International Commission on Illumination). 2.0.37 Glare rating(GR) The psychological rating of human eye discomfort subjective response caused by the light emitted from lighting device of sports venue and other outdoor yard, which is measured by CIE (International Commission on Illumination). 2.0.38 Glare by reflection The glare caused by the reflection in the view, particularly generated by reflection image close to sight line direction. 2.0.39 Veiling reflection The specular reflection of visual object, it r... ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 50034-2024_English be delivered?Answer: Upon your order, we will start to translate GB/T 50034-2024_English as soon as possible, and keep you informed of the progress.
