The main measures to limit glare in outdoor lighting:
1. Keep the light out of the strong glare angle range. For example, the stadium floodlight should have a certain height, so that the depression angle of the floodlight is more than 25 degrees, so that the vision of athletes and spectators can avoid the interference of strong glare.
2. Select light-cutting lamps. In the fast-speed highway lighting, in order to avoid the glare caused by the front street light source to the driver, the light-cutting lamps should be selected. The lamps block the part of the light that causes glare, creating a good driving visual environment for the driver. In the design of road lighting, street lights are not installed in front of the road at the T-junction, which is also intended to prevent the street lights from appearing in the glare area of the driver's vision.
3. Reduce the brightness of the light source. In outdoor lighting such as courtyard lighting, railing lighting, advertising sign lighting, etc., in order to reduce the glazing caused by the high brightness of the light source, a frosted glass cover and a PC tube translucent material are added outside the light source, which effectively reduces the material and the light source. brightness. Some lamps use grilles, reflectors, etc., also to block glare.
4. Appropriately increase the background brightness. In order to increase the brightness of the venue and reduce glare, some stadiums use luminous ceilings.
5. Increase the luminous area. In order to reduce the glare caused by strong light sources and increase the light-emitting area, multiple small light sources can be used to replace one large light source.
6. Avoid glare caused by reflection. In the lighting of swimming pools illuminated by strong light sources, the positions of lamps and lanterns should be reasonably determined through calculation, so as to avoid glare caused by the reflection of lights on the water surface to the referee and the audience. Glass screens, etc. will cause glare, so use with caution.
