compared with the traditional street light, LED street lamp is more energy conservation and environmental protection, the brightness is higher, so they are widely used in municipal road engineering construction. To the large volume of each year to purchase the LED street lamp, but some of the LED street light after a long period of time will suddenly put out, what is the reason of this phenomenon? Generally speaking, the led street lamp fault can be divided into all the failure and partial failure. If not all of the lights on, consider the led street lamp is tripped. If so, the brakes directly. If the power open, all the lights are still closed, so LED street lamp driver problems should be considered. Usually, in this case, please contact the street lamp manufacturers to replace the new driver. If some of the light not bright, may be some leds lamps internal defective or damaged. We should consider the following: 1. The poor quality of 1. Light emitting diode chip at present, the light emitting diode chip on the market are of variable quality, poor quality of some of the light emitting diode chip, short service life, in a short period of time will be damaged, will not appear the phenomenon of luminescence. 2. Radiator radiator performance is bad performance is bad, led street lamp head internal heat is too high, more than the chips are the highest temperature, lead to light emitting diode chip is damaged, the phenomenon of light emitting diode chip is not bright. 3. Drive damage damage can also lead to other drive of power led street light component cannot work normally. In fact, there are many factors leading to the invalid LED lights suddenly, so I will not tell you one by one. However, we need to pay attention to the fact is that we want to led street light has a long service life. Should choose when buying reliable street lamp manufacturers, and pay attention to the usual regular maintenance, to ensure the stability of the LED street lamp.
