International Standard Street Light Contrast Illuminance
Classification of road lighting: The international commonly used road lighting classification standards are determined according to the type of road and traffic flow. Common classifications include highways, major roads, minor roads, residential areas, and pedestrian areas. Each classification has corresponding lighting requirements and illuminance levels.
Illuminance level: Illuminance refers to the level of illumination on the road or sidewalk, usually in Lux (Lux). Illumination levels are set according to different road types and uses to ensure a safe and comfortable lighting environment.
Highways and major roads: Higher illuminance levels are usually required to provide good illumination and visibility over long distances. Illumination levels are usually between 20 and 50 lux.
Minor roads and residential areas: Relatively low lighting requirements, mainly to provide basic lighting and visibility. Illumination levels are usually between 10 and 20 lux.
Pedestrian area: For pedestrian areas, higher illumination levels are required to ensure the safety and comfort of pedestrians. Illumination levels are usually between 20 and 50 lux.
Uniformity of illuminance: In addition to illuminance grades, international standards also require uniformity of illuminance on the road. That is, under the same road lighting classification, the illuminance should be evenly distributed in a specific area to avoid excessively bright or too dark situations. Uniformity of illumination requirements help provide a consistent visual environment and reduce glare and shadows.
Specific international standards and specifications may vary from region to region, and each country and region may have different road lighting design standards and requirements. Therefore, when designing and installing street lights, it is best to refer to local standards and regulations, or consult a professional lighting engineer to ensure the rationality and effectiveness of the illuminance level and illuminance uniformity.
To sum up, international standards for street lamp illumination requirements will be classified according to road type and traffic flow to determine the corresponding illumination level. At the same time, the uniformity of illumination is also an important consideration.
