The utilization rate of high-power floodlights is very high today, so its failures are relatively few, but some problems are unavoidable. One of the faults is that the high-power floodlight is not on. Today’s Aluminum Lamp Housing Wholesalers introduction will discuss how to properly repair high-power floodlights that do not turn on.

The life of high-power floodlights is determined by light decay. Generally speaking, the longer it is used, the greater the light decay, and the brightness of the lamp will become darker and darker until it stops bright and cannot work normally. There are two reasons for the light decay, one is the light decay of the blue LED itself, and the other is the luminous decay of the phosphor. The light decay of different high-power project-light lamp housings is also different. The light decay of an LED is related to its junction temperature. The junction temperature is the temperature of the semiconductor PN junction. Generally speaking, the higher the junction temperature, the earlier the light decay occurs, and the shorter the lamp life.

In order to increase the service life of high-power floodlights, the key is to reduce the junction temperature, and lower junction temperature regulations must have a good heat sink. In general, if you want to make high-power floodlights longer life, you need The radiator selected is an aluminum radiator with the best heat removal effect at this stage.
