How many ways are there for energy-saving transformation of street lighting?

The first kind of street lamp transformation is to replace the existing street lamp caps, which is to replace the traditional high pressure sodium lamp or metal halide lamp with a new type of LED light source. Take the traditional 250w high-pressure sodium lamp (existing street lamps are mainly high-pressure sodium lamps). The power consumption is 250w, plus the power consumption of the finisher and its own consumption are more than 300w. After several years of use (High-pressure sodium lamp life is 3000 hours), the power consumption of the system will reach 400w, and it can be replaced by a 100w led street light under the same brightness, or the led street lamp can save half of the power under the same brightness. The power consumption of high-pressure sodium lamps is a huge waste, and it is urgent to transform traditional street lamps, and most of the street lamps in many parts of the world use this kind of 250w high-pressure sodium lamps.According to the current situation, the three main ways of

street lighting renovation are as follows:

Use led street lights to transform traditional street lights (just replace the lamp cap with led light source, other parts remain unchanged), the existing 250w high pressure sodium lamp can be replaced with 120w led light source, now the number of lumens per w of led street lights is 100 Up to 130, the better LED street light can reach 140 to 170 lumens per w, and now they can basically replace 250w high pressure sodium lamps. With the existing technology, 100w LEDs can completely replace 250w high pressure sodium lamps.

The second kind of street lamp renovation is to upgrade street lamps on the existing basis, that is, install a single lamp controller on the existing street lamp, which is a new product of the Internet of Things technology. The new single lamp controller can make street lamp control intelligent and 0 -10v dimming and power reduction; it not only improves the overall control of urban street lights and realizes intelligence, but also achieves the purpose of energy saving and emission reduction.

The third kind of street lamp transformation is to change the city circuit lamp to solar street lamp. Because solar street lamp is a kind of street lamp using solar energy as energy source, it is not affected by conventional electricity, does not need to dig trenches and bury wires, and does not consume conventional electricity. It can be used as long as it is in a sunny place. It has the advantages of safety, no hidden danger, energy saving, no consumption, and environmental protection.

In fact, there are many ways to retrofit street lights, such as adding power savers, etc. However, since actual use does not bring good retrofit effects, it is not recommended.

In summary, there are three main ways to renovate street lighting, the most used is the first one. With the continuous update of led street light technology and the decrease in cost, I believe that more and more people will choose led street light to replace Low-efficiency power-consuming high-pressure sodium lamps,which can achieve the purpose of energy saving and emission reduction.
