The top 5 factors affect the led lights quality
1, Heat dissipation
The heat accumulation of the LED chips not only affects the electrical performance of the LED, but may also eventually lead to LED failure. Therefore, in order to ensure the life of the LED lamp, heat dissipation becomes a key technology for white LED applications, and reducing or rapidly dissipating the heat generated by the LED becomes the primary problem in the application design of the white LED.
For this point we can check carefully the lamp’s heat sink to see if they are in good quality and good function. Usually judged by the material, size, and compactness with the lamp body.
2, The light source material
LED is a point light source. If poor quality LED chips is used, the chips will release a lot of heat during working, which will make the junction temperature rise rapidly. The higher the LED power, the greater the heating effect. The LED chip temperature will rise. The change in the performance of the light-emitting device and the electro-optical conversion efficiency are attenuated, and sometimes even can’t work any more in serious cases.
3, The driver power
The quality of LED power supply directly effect the reliability of LED products. Therefore, the requirements of efficiency conversion, effective power, constant current accuracy, power supply life and electromagnetic compatibility of LED driver power supply are very high for the customers in the market. Because the power supply play a role for a luminaireis is just as important as a human heart.
