If you look down from a height, you will find that many metropolises have a little bit of orange light. These orange lights are emitted by tens of thousands of high-pressure sodium lamps. In the past, high-pressure sodium lamps were very common, and they could be seen in the streets. However, with the road lighting revolution, LED street lamps gradually replaced traditional high-pressure sodium lamps with their own advantages. LED lamps have a long service life. Energy efficient, safe and worry-free.

It is estimated that the total number of street lamps in the United States is between 45 million and 55 million, most of which are high-pressure sodium lamps, and a small number are metal halide lamps. However, experts say that the adoption speed of LEDs has increased in the past two years. Because of the use of LED lamps, the quality of light has improved significantly, and the power savings are very obvious.

First, the light from the good quality LED street light is clearer and more beautiful. The optics in LED luminaires are designed to be precise enough to ensure that light is shining where it is located, which ensures less wasted light.

Second, the maintenance cost and energy consumption of LED lamps are very low. Because most of the road lamps are managed by public utility companies, the energy consumption can be reduced by nearly 40% after using LED street lamps. More critical. The lumen output of the high-pressure sodium lamp will decrease year by year, so the high-pressure sodium lamp must be replaced every five years or so. Lamp replacement is too frequent and consumes a lot of manpower and material resources. The life of LED lamps is three to four times longer than that of ordinary high-pressure sodium lamps, which can save a lot of maintenance costs.

Third, today"s street lights are not only used for lighting, but also for decoration. With the advancement of technology and the reduction of manufacturing costs, more and more manufacturers have begun to produce highly decorative street lamps, with a strong sense of technology and a design that resembles the old-fashioned gas lamp. They are very aesthetically pleasing.

A few years ago, LED lamps only occupied a small part of the road lighting market, but at that time the cost of LED lamps was high. Most towns and towns still chose traditional high-pressure sodium lamps, but with the continuous innovation of LED lamps and the decline in lamp costs, LEDs Luminaires began to gradually replace traditional street lamps. I believe that in the near future, road lighting will be the home of LED lamps.
