Domestic high-voltage LED driver

LED life is far lower than the theoretical life, a big reason for this is that the LED light temperature is too high, resulting in accelerated aging of LED lamp using high-voltage LED driver, resulting in decline due to light, and the recent emergence of high-voltage constant-current power transformer, electrolytic capacitor to solve the problem of low voltage LED drive power and the life of electrolytic capacitors.

 Domestic high-voltage LED driver

In addition to the driver chip, the drive power of the low-voltage LED lighting, another key device electrolytic capacitors. The operating characteristics of the high temperature of the electrolytic capacitor determines the life of LED lamp using high-voltage LED driver, traditional lighting structure has little free space left to the LED lighting, electrical connection is the physical interface of the general lighting the lamp above the power module in the lamp and LED light and beads, LED light beads after the electrical work, a lot of heat rise, accumulate in the narrow space of the lamp, easy to distribute. The technology to produce led high bay lighting products measured temperature of 70 to 110, the entire drive power LED lighting modules must be suitable for such a high heat environment. LED lighting heat problem is not resolved, not only affects the normal working of the drive power, and affects the life of the electrolytic capacitor, will eventually lead to the LED lamp light fades early, the whole LED lamp life.

 

Compare to exited international high-voltage LED driver, domestic products need to be improved. There still a lot of things left to be finished, however, engineers and designers look to the future with optimism.
