Why choosing LED as light source for solar street lights ? – its advantages over ordinary light sources

In the past years, we have been using high pressure sodium lamps for road lighting. In recent years, as new energy sources have been used more and more, we have gradually replaced high-pressure sodium lamps with solar LED street lamps. LED light source features of energy saving and environmental protection, it is more economical from a long-term perspective, but are these all the reasons why we choose LED lights to replace high-pressure sodium lamps?

In fact, the LED light source has more advantages than the ordinary light source in the actual usage. In other words, it is not only more energy-efficient, but also more practical. Today, let me introduce more advantages of LED light source for you.

1. Color temperature
The high-pressure sodium lamp exhibits a yellow-white color and a low color temperature, which results in a poor service in some streets where the high illumination is required, and if the installation distance between each is reduced, a certain cost will be added. The LED light source is white light, not only that, but its color temperature can also be flexibly changed between 4000K and 7000K, which means it can give more choices to actual needs.

2. Color rendering index
The color rendering index of LED light sources is generally above 80, while the color rendering index of high pressure sodium lamps is only around 20. It can be seen that the LED light source is closer to natural light and can bring better lighting effects.

3. Beam angle
The beam angle of high-pressure sodium lamp is 360°. In most cases, it is necessary to reflect the light source through the reflector, and then it is possible to reach the designated area to achieve the illumination effect. In most cases, the beam angle of the LED light source can be kept at the same angle as the illumination angle of the lamp. In short, most of the LED light source can directly illuminate to the designated area.

4. Startup time
The high-pressure sodium lamp has a certain startup time, usually it takes about 5-10 minutes after power-on to work normally. If it is started again after extinction, it takes about 5 minutes. The LED light does not have this problem. It can work immediately after power on, and it can be started at any time without waiting. The solar LED street light can be operated automatically after dark, which is more convenient and quicker.

It can be seen that in actual use, LED light source has more advantages than ordinary light source, which makes us more convinced that the advantage of using solar street light than high-pressure sodium lamp.
