Terms and definition of illumination, 4)

Light pollution light pollution light pollution disruptive or excessive radiation ( With visible light, ultraviolet and infrared radiation) To human health and the negative influence of the human survival environment. Outdoor lighting light pollution of light pollution from exterior lighting is mainly because of building facade lighting, road lighting, square lighting, advertising lighting, lighting, the stadium and the parking lot outside interference function and landscape lighting light to person, environment, astronomical observation, the floorboard of the negative impact caused by transportation. Obtrusive interference light light discharge astigmatism overflow scattered, directional and spectrum, the three effect of human activities and harmful effect on the plants and animals or interference of light. （ CIE definition: excessive number of astigmatism in a particular situation, the direction or spectral cause trouble discomfort, distracted or visual information in the light) 。 Astigmatism spill spill light scattering and radiation from lighting device to lighting outside the scope of the light. Reflected light reflected light outdoor lighting light through metope, ground reflection to the surrounding space, or any other exchanges of people and environment interfere light; Valve taking incremental threshold increment caused by road lighting lamps and lanterns of disability glare and reduce visual identification indicators of brightness contrast may be increased. Sky light or the sky glow sky glow from the gases of the atmosphere molecules and aerosol scattering ( Including visible and not visible) The light reflected, formed in the direction of the astronomical observation night sky brightness phenomenon. Natural sky glow: bodies and the earth's upper atmosphere process causes the part of the sky glow; Artificial sky glow: artificial source form part of the sky glow, Outdoor artificial lighting) , it includes direct upwards and the ground reflection to the optical radiation in the air. Light output ratio (upward ULOR） Upward Light Output thewire lighting facilities in a standard design conditions, the lamps and lanterns of lighting Light source or to refer to the above water flux Ratio. The actual light output ratio (up ULOR inst) 安装( ULOR） 。 Lighting in the actual installation position ( Conditions) Or lamps and lanterns, a source to a reference level above the flux. Curfew is strict Curfew interference light pollution control of time, usually is the government management departments, especially the application of lighting control of local government a time segment. Environment of regional Environment zones according to the plan or activity content, the limitation on the interference light pollution put forward the corresponding requirements of the area. Area is divided into E1 to E4, a total of four regions ( That 4 the scope and limit of light pollution requirements, as shown in the Beijing institute of lighting the city night view lighting technology guide chapter 19 table 19. 13) Related terms illumination Lighting the object and its environment through a kind of measure that is visible light. Broadly also includes the application of ultraviolet radiation and infrared radiation. Light Luminous environment ( 光) The environment lighting system ( Natural light and artificial light) And photometric characteristics of all surfaces in the environment comprehensive effect. Lighting Lighting technology Lighting technology and the combination of scientific principles, including access to light, the application of light and metering technology, etc. Lighting Lighting system Lighting equipment according to the installation place or use function constitutes the basic pattern. City Urban lighting lighting city function the floorboard of the lighting and landscape lighting at night. Outdoor lighting Exterior lighting of the building outside, other than road traffic lighting lighting parts, including outdoor job site, Site and wharf, etc. ) Lighting, security lighting, sports and entertainment venue lighting, square lighting, city night view lighting, advertising lighting, etc. Green lighting Green towns to save energy and protect the environment, is beneficial to improve people's learning, work efficiency and quality of life and guarantee the physical and mental health of lighting.
