[Street lamp manufacturers] How to identify the quality of LED street lamps

With the increasing shortage of global energy, LED technology is becoming more and more widely used, especially in the field of LED street lights. In just a few years, it has developed into a sunrise industry. The number of street lamp manufacturers is also increasing, the market competition is increasing, and the price of LED street lamps is indeed getting lower and lower, but the quality of LED street lamps has become uneven. Consumers will choose poor quality LED street lights if they are not careful, causing problems such as short service life. So next, street lamp manufacturers will teach you how to distinguish the quality of LED street lamps.

One, look at the radiator

At present, the heat dissipation system of street lamps is divided into die-cast aluminum, aluminum profile and unicorn, among which aluminum profile has better heat dissipation. Also pay attention to whether the heat dissipation capacity of the radiator is sufficient. Many street lamp manufacturers originally use W-cooled LED street lamp lamps to install W to save costs, so that their cooling system will not keep up, and the light decay will be relatively large. Seriously affect the service life of LED street lights.

Two, look at the LED chip

The LED chip is the core part of the LED street lamp. The quality of the LED chip affects the service life, brightness, and light attenuation of the LED street lamp. The quality of LED chips of general brands is good (such as Bridgelux, Philips, etc.). Try not to use fake or brand-name LED chips.

Three, look at the power supply

Pay attention to what power supply is used for street lamps, cross-current or constant voltage, and power brand. Generally, constant current power is more stable and the quality of big brands is better. Try not to choose LED street lights with brand-name power supplies.

Fourth, look at the brightness

Pay attention to the brightness of LED street lights. The brightness of LED street lights is an important factor that directly affects the use effect, and the brightness of LED street lights generally reaches about LM/W. Generally, the higher the brightness per watt, the higher the lumen value. When necessary, the street lamp manufacturer can provide the test report of the LED street lamp.

Finally, we should also pay attention to the warranty time of LED street lights. Generally, with good quality LED street lights, street lamp manufacturers will dare to have a warranty of years and above. The above points can be used for reference when distinguishing the quality of LED street lights. But in any case, it is what we want to buy cost-effective products at the right price.
