LED street lamp manufacturers analyze the causes of street lamps tripping after two hours of lighting

Road lighting has become a part of people's lives. The use of street lights greatly facilitates people's night life and ensures the safety of people traveling at night. With the rise of LED technology, LED street lamps are replacing traditional street lamps with an unstoppable trend. LED street lights have great advantages, but they may also fail. Some people will trip after two hours of lighting after installing it. Today, LED street lamp manufacturers will analyze the cause of the LED street lamp tripping after two hours of lighting for this problem.

.Street lamps do not dissipate heat well. After the LED street lamp lights up, as the temperature rises, the internal resistance of the street lamp lamps changes, causing the protection device to overload.

.The margin reserved for the rated power of the switching power supply is too small. When the load power of the LED changes with temperature, it will quickly cause the switching power supply to overload.

.Some electronic devices have temperature rise protection. When the heat dissipation of the LED street lamp is not good, if the temperature rise protection device is also selected, it is easy to produce temperature rise protection.

When this problem occurs, we must first consider the above three reasons. If the above reasons are not eliminated one by one, we must also consider whether the laid cables are suddenly damaged and short-circuited due to irregular installation and construction. Or the power of the purchased wire is small. In addition, the purchase editor gives you a small suggestion. When buying LED street lights, you must understand the power supply, LED lamp beads and the quality of the radiator, and try to buy from larger LED street lamp manufacturers.
