LED Road Light Is The 21st Century, The Most Promising Green Lighting Source
Oct 18, 2017

LED as the world's most eye-catching new generation of light source, because of its high brightness, low heat, short life, non-toxic, recyclable and other advantages, is known as the 21st century, the most promising green lighting. Here we look at the purchase of LED lights need to pay attention to the main points.

1. Luminous efficiency

LED lighting technology matures, high-power LED light source has been able to meet the general needs of the luminous flux. General high-pressure sodium lamp luminous flux is 100LM / W, commonly used high-power LED is 50-60LM / W, with the best foreign LED chip can reach 80LM / W, the higher the luminous efficiency, means that the better energy-saving effect, which is Choose one of the most important indicators of LED lights. However, the LED standard is not clearly defined in this, so the purchase of LED lights must be carefully confirmed.

2. LED lights light failure

Now some businesses, in order to reduce costs, on the use of hundreds of 0.5W low-power LED. However, this low-power LED's light failure is very serious, its light failure to 80% of the life of only 1000 hours. Therefore, as long-term use of the street is absolutely can not allow the use of this low-power LED, the choice of high-power LED (generally refers to more than 30W), the light failure is much better.

3. LED lights own weight problems

LED lights due to high technical content, composition and other complex reasons, some high-power lamp weight will be far more than ordinary high-pressure sodium lamp, so the corresponding support material requirements are higher. However, some LED lights manufacturers have been as much as possible to reduce the weight of the LED lamp, from the original single lamp about 30 kg, down to more than 10 kilograms, the weight of the reduction there is a further downward trend.

4. LED street lamp cooling

LED because it is a semiconductor component, the chip affected by the temperature and reduce the initial luminous flux of 30%, it will lose the meaning of lighting, that is, the end of life, theoretically high power LED lights life of 3-5 million hours, but Its important premise is to have good heat dissipation. It is worth mentioning that the domestic manufacturers have adopted the world's leading needle-like heat dissipation technology.
