How to judge the quality of solar powered security lights beads?

  With the increasing shortage of global energy, the use of LED technology is becoming more and more extensive, especially in the field of solar powered security lights. In just a few years, it has developed into a sunrise industry. The number of solar powered security lights manufacturers is also increasing, the market competition is getting bigger and bigger, the price of solar powered security lights is indeed getting lower and lower, but the quality of solar powered security lights has become uneven. If consumers accidentally choose a poor quality solar powered security lights, it will cause problems such as short service life. So outside solar lights manufacturers will teach you how to identify the quality of outside solar lights.

  First, look at the radiator.Now the street lamp cooling system is divided into die-cast aluminum, aluminum profiles and cymbals, of which aluminum profiles have better heat dissipation. Also pay attention to whether the heat dissipation of the radiator is sufficient. There are many street lamp manufacturers use 90W heat-dissipating outside solar lights in 120W outside solar lights, so that their heat dissipation system will not keep up, seriously affecting the service life of solar powered lights.

  Secondly, look at the LED chip.The LED chip is the core part of the solar powered lights. The quality of the LED chip affects the service life, brightness and light decay of the LED street lamp. The quality of general brand LED chips is good (such as Bridgelux, Philips, etc.). Try not to use cottage or brand LED chips.

  Thirdly, look at the power supply for the solar powered lights.It is necessary to pay attention to what kind of power supply for solar powered led street lights, cross-flow or constant voltage, as well as power brands, generally using constant current power supply is more stable, and the quality of big brands is better. Try not to choose a street lamp with a brand of power supply.

  Fourth, look at the brightness of solar powered led street lights.Pay attention to observe the brightness of the solar powered led street lights. The brightness of solar powered led street lights is an important factor that directly affects the use effect. The brightness of solar panel street light generally reaches about 140LM/W. Generally, the higher the brightness per watt, the higher the lumen value. When necessary, solar panel street light manufacturers can provide test reports for solar panel street light.

  Finally, we must pay attention to the warranty time of solar panel street light, general quality solar street lighting system, street lamp manufacturers will dare to warranty for 3 years and above. The above points can be used for reference when identifying the quality of solar street lighting system. But in any case, using the right price and buying a cost-effective product is what we want.
