main problem of led street lamps
With the country's emphasis on energy conservation and emission reduction and the urgency of energy-saving transformation, Guangdong Province will also vigorously promote LED street lamps, while the LED street lamp scheme promoted by Guangdong Province has been widely questioned. The reason is that LED street lamp products have many problems, such as: light decay, heat dissipation problems, light ability, etc.
Energy saving but insufficient light
Energy saving is the energy saved under the same average illuminance. The average illuminance can't just be the average illuminance on the ground! The light intensity of the space has a good early prediction for vehicles coming from a distance to prevent traffic accidents! But domestic installations Most of the LED street lights sacrifice illuminance to achieve energy saving.
The heat dissipation problem of LED street lights
Street lamps are used outdoors, so they must be waterproof and dust-proof, so the lamps must be sealed. The temperature of the water vapor in the lamps after sealing exceeds 100 degrees under extreme weather conditions. LEDs work continuously in such a high temperature environment. If the LED street lamps do not dissipate heat If it is done well, the lamp will be extremely easy to be broken or severely decayed. The heat dissipation problem of domestic high-power LED street lights has not been completely solved, and the subsequent maintenance costs of the products will inevitably increase.
The penetrability of LED lights
In rainy and foggy days, the ability of LED light lines to penetrate fog is not strong.
Easy to attract mosquitoes outdoors
Because mosquitoes particularly like the light of certain wavelengths of LED lights, there is a phenomenon of moths fighting the fire, which will affect its light efficiency.
To sum up: LED as a new light source has irreplaceable advantages in replacing incandescent lamps and fluorescent lamps, but there are still some problems in the use of high-power LED street lamps. The promotion of radical and comprehensive replacement of LED street lights (especially on main roads) may cause sequelae. If extreme weather is encountered, a large number of lights may be broken or severe light degradation may affect road safety.
