As a large lighting appliance that can be seen everywhere in our daily life, the high pole lamp produced by the high pole lamp manufacturer is loved by people because of its wide irradiation range and high brightness. High - bar lamp some high - pressure sodium lamp, some LED light source. Which of them has the advantage? Which is better? These are headaches for home buyers. Today, the high pole lamp manufacturer tells you how to use the light source type of the high pole lamp.

1. First of all, high pressure sodium lamp, its light color is yellow, low color temperature, low color index. The color index of sunlight is 100, but the color index of yellow high-pressure sodium lamp is only about 20. The color temperature of LED light source can be arbitrarily selected between 4000-7000K, and the color rendering index is above 80, which is closer to the color of natural light. As for the color temperature of high pressure sodium lamp, white light is about 1900K. Because high pressure sodium lamp is color light, low color, "color temperature" has no practical significance for sodium lamp.

2. The bulb of high-pressure sodium lamp takes a long time to start, so it needs a certain interval to start again. It takes about 5 to 10 minutes to reach normal brightness after the system is powered on, and more than 5 minutes to restart the system. LED light source does not have the problem of long start-up time, can work at any time, easy to control.

3 for high pressure sodium lamp, the utilization rate of light source is only about 40%, most of the light must be reflected through the mirror to illuminate the specified area. While the utilization rate of LED light source is about 90%, most of the light can be directly illuminated to the designated area, only a small amount of light needs to be reflected.

4. The life of ordinary high pressure sodium lamp is about 3000-5000 hours, and the life of LED light source can reach 30,000-50000 hours. If the technology is more mature, LED lights can last up to 100,000 hours.
