We all know that social development is now better, every way will be installed street lights, so that people's lives to provide a great convenience, when people in the night when the time, do not worry about the problem of money. led lights are more common, then the following for you to introduce the advantages of led lights?
What are the advantages of led lights?
1, its own characteristics - the one-way light, no light diffusion, to ensure the efficiency of light.
2, LED lights have a unique secondary optical design, the LED lights light irradiation to the required lighting area, to further improve the efficiency of light to achieve energy-saving purposes.
3, LED has reached 110-130lm / W, but also a lot of room for development, the theoretical value of 360lm / W. And the luminous efficiency of high-pressure sodium lamp is increased with the power increased, therefore, the overall light effect LED street lamp than the high pressure sodium lamp; (the overall light effect is theoretically, in fact more than 250W high pressure sodium lamp light efficiency than LED lights ).
4, LED lights light color than high pressure sodium lamp much higher, high pressure sodium lamp color rendering index is only 23 or so, and LED street light color rendering index of 75 or more, from the visual psychological point of view, to achieve the same brightness, LED lights, the average light Than the high pressure sodium lamp to reduce more than 20%.
5, light fades small, less than 3% of the light of one year, the use of 10 years still meet the road requirements, and high pressure sodium lamp decline, about a year has fallen more than 30%, so LED lights in the use of power design Can be lower than the high pressure sodium lamp.
6, LED lights have automatic control of energy-saving devices, to meet the lighting requirements in different periods of time to meet the likely reduction in power, saving energy. Can achieve computer dimming, sub-time control, light control, temperature control, automatic inspection and other human features.
7, long life: can use more than 50,000 hours to provide three years of quality assurance. The downside is that the life of the power supply is not guaranteed.
8, high luminous efficiency: ≥ 100LM above the chip, compared to the traditional high pressure sodium lamp can save more than 75%.
9, easy to install: no need to add the cable without rectifier, etc., will be installed directly on the pole or the original light source nested lamp shell.
10, excellent heat control: summer temperature control in the following 45 degrees, and the use of passive cooling, summer heat protection.
