Compared with traditional lamps, LED lamps have these characteristics: energy saving, long life, and environmental protection. However, there are different quality levels of the LED lighting market. How to choose the right one? Here are some factors you should consider:
1. The power factor. If the power factor is too low, it means that the design of the power supply circuit is not good. This will greatly reduce the lamp life and lumen output. Therefore, it is best to choose a power factor of up to 0.5, and for better quality, it should be 0.85 to 0.9.
2.Material of fixture body. The most commonly used material today is aluminum. It is best to aluminum type, the second is automobile aluminum (aluminum extrusion aluminum), and the worst is cast aluminum alloy. Inserted aluminum has the best heat dissipation.
3.3. The brand of the chip.
First-class brands should come from Europe, the United States and Japan alike, Cree Company, Osram, Toyoda Gosei, etc.
The second type of brands are from the United States, South Korea, Taiwan, Seoul, like Pry, crystal Photonics, New century, etc.
The third category is domestic brands in China, such as SAN 'an, Blu-ray.
The quality of the chip determines the lumen output of the fixture.
4. The quality of the driver.
The life of the power supply will affect the overall life of the LED lamp. In theory, the life of the chip is 50,000 hours to 10,00h, and the life of the driver and work to 20,00h. The driver material is designed to determine the life of the LED luminaire.
5. Lumen efficiency.
Power consumption of the same chip, higher luminous efficiency, high brightness output; Same lumen output, less power consumption, more energy saving.
6. Power conversion efficiency.
The power conversion efficiency is higher and better, which means lower power consumption and higher power output.
7 Certificate
If the LED luminaire is certified, it means that the quality is higher.
8. Technology
Good workmanship, quality should be higher.
