The illumination standards of road lighting fixtures play a vital role in ensuring driving safety and improving driving comfort. This article will introduce the illumination standards of road lighting fixtures and their importance to help everyone better understand and use lighting fixtures.
The illumination standard of road lighting fixtures refers to the minimum illumination requirements achieved by the light source provided by the street lamp in different road scenarios. Illuminance refers to the luminous flux of light received per unit area, usually expressed in lux. Different types of roads should set corresponding illumination standards according to specific conditions.
Generally speaking, urban roads are divided into expressways, urban arterial roads and secondary arterial roads, and the illumination standards for each type of road are different. Taking highways as an example, according to national standards, the illumination standard for highways is 20-30 lux. This is because the speed of vehicles on the highway is faster and the reflection time of vehicles passing by is shorter, so the illumination requirements are relatively low to avoid glare and visual fatigue.
For urban main roads, due to the large traffic flow and generally low vehicle speeds, the requirements for illumination are relatively high. According to the standard, the illumination standard for urban main roads is 20-50 lux. Such illumination can better illuminate the road, improve driving visibility and reduce the possibility of accidents.
The illumination standards for secondary roads and residential areas are generally 10-30 lux. This is because secondary arterial roads mainly connect urban main roads and residential areas, with relatively small traffic volume and low vehicle speeds. Roads in residential areas are usually alleys between lighting fixtures and residential buildings, which have lower lighting requirements.
Reasonable setting of illumination standards can not only meet the needs of driving safety, but also provide good driving comfort. Too high illumination will cause glare and visual fatigue, while too low illumination will reduce driving visibility and bring safety risks. Therefore, reasonable selection of illumination standards is crucial to ensuring driving safety and improving driving comfort.
The illumination standard of road lighting fixtures is an important factor in ensuring driving safety and improving driving comfort. Different types of roads should set corresponding illumination standards according to specific conditions, not only to consider driving safety, but also to ensure driving comfort. We should actively pay attention to the illumination standards of road lighting fixtures, choose appropriate lighting fixtures, and provide a better lighting environment for driving.
