How to Choose LED Street Lamp for Various Applications?
Because of working outdoors for a long time and the bad working environment, Roadway LED street lamp must meet the higher requirements in the aspect of optical properties, mechanical strength, dustproof waterproof level, corrosion resistance, heat resistance, electrical insulation properties. Then how to choose street lamp for various applications?
Firstly, select the appropriate led road lamp according to the lighting requirements of road, interchange, plaza and other using areas.
- •Roads of the yard and residential district, pedestrian street of the commercial district, the square and other places, they will be installed on higher mechanical strength street lights.
- •We can select cut-off or half cut-off lamps for collector streets as a general rule.
- •Basically, we choose the Flood LED Lamp for high mast lighting.
Secondly, choosing the Roadway LED street light according to the application of dustproof and waterproof requirements.
