LED Street light are becoming more and more popular in the market, they are very easy to use in use, and are very environmentally friendly. Their service life is generally very long, but there will be a large number of substandard products in major shopping malls. Cause a lot of trouble? Let's take a look at how to distinguish the quality of led lamps and lanterns!

1. Look at the overall "power factor of lamps": the power factor is low, indicating that the driving power supply and circuit design used are not good, which will greatly reduce the service life of the lamps, and the power factor is low. President.

2. Look at the driving power used by the lamps. The service life of the power supply is much shorter than that of other lamps. The life of the power supply affects the overall life of the lamp. The theoretical life of the lamp beads is 50,000-100,000. hours, and the life of the power supply is 0.2-30,000 hours, the design and material selection of the power supply will determine the service life of the power supply.

3. Look at "Lamp heat dissipation conditions - data and structure": The heat dissipation of LED lamps is also very important. Lamps with the same power factor and lamp beads of the same quality, if the heat dissipation conditions are not good, the lamp beads will work at high temperature, and the light decay will be very high. large, the lamp life will be reduced.

4. Look at "lamp bead quality": lamp bead quality depends on chip quality and packaging skills.

5. Look at the power supply. The higher the power supply, the better. The higher the power supply, the smaller the power consumption of the power supply itself, and the greater the output power.

6. Is it in compliance with safety regulations? China's LED lamps and lanterns safety regulations have been issued, please choose led lamps according to the national safety regulations.

7. Look at the light effect: the same lamp bead power, the higher the light effect, the higher the brightness, the same lighting brightness, the lower the power consumption, the more energy-saving.

8. It depends on whether the street light Manufacture workmanship is fine.
