The renovation of street lamps in Wenzhou City will be upgraded, and the LED light source will replace the traditional high-pressure sodium lamp.

Recently, the city road in Wenzhou City is undergoing road lighting renovation and upgrading. The LED light source on the taller level will replace the traditional high-pressure sodium lamp and become the illumination source for the citizens to travel at night.

The renovation of street lamps in Wenzhou City will be upgraded, and the LED light source will replace the traditional high-pressure sodium lamp.

In May of last year, the Municipal Administration Office began to try to install the proposed LED light source. After passing the test and inspection and meeting the requirements, it started in August last year, and the urban district plume lights were replaced by LED light sources.

The renovation of street lamps in Wenzhou City will be upgraded, and the LED light source will replace the traditional high-pressure sodium lamp.

It is understood that this urban street light source transformation is to take advantage of the high utilization rate of LED light source, long service life, light illumination, good color rendering, more energy saving and environmental protection. The conventional high-pressure sodium lamp is a light source that emits light in a full space, and actually emits less light in the direction of the road; and the LED lamp emits light in a single direction due to the light-emitting surface, the light flux loss is small, and the light source utilization rate is high. In energy conservation and environmental protection, traditional high-pressure light sources contain metallic mercury and metallic sodium (which become mercury vapor and sodium vapor after power-on), and subsequent waste disposal is environmentally polluting; while LED is a solid light source, without any gas, street lamps do not contain harmful Metallic mercury is relatively safer and more environmentally friendly, and waste has less environmental pollution. In addition, in the color rendering performance, the high-pressure sodium lamp has a low color rendering index, poor color rendering, and poor color reproduction of the object itself, which is not conducive to judging the depth of the surrounding environment; the LED light source has a high color rendering index and good color rendering, which is good. The actual color of the ground restored object is closer to the natural light color. Another point is that the traditional high-pressure sodium lamp has a service life of 1 to 3 years, while the average life of LED lamps is more than 5 years.

The renovation of street lamps in Wenzhou City will be upgraded, and the LED light source will replace the traditional high-pressure sodium lamp.

At present, Wenzhou City has completed the replacement of more than 30,000 street light sources. It is expected that nearly 40,000 LED street lights will be installed in the first half of this year.
