LED cooling power supply thermal design

Led dimming power supply is characterized by high quality, durability and energy saving. The projection angle adjustment range is large. The brightness of 15W is equivalent to an ordinary 40W dimming power supply, which is resistant to high temperature, moisture, water, and leakage. Led dimming power supply voltage: 110V, 220V optional, optional glass or PC cover material, the lamp head and ordinary dimming power supply.

Under low current, led dimming power supply temperature rise is not obvious, if the ambient temperature is higher, the main wavelength of led dimming power supply will be red-shifted, the brightness will decline, uniformity of light, consistency worse, especially dot matrix, large display The temperature rise of the screen has a more significant effect on the reliability and stability of the led dimming power supply, so the thermal design of the led dimming power supply is critical.

Working for a long time will cause aging due to light failure, especially for high-power led dimming power supply, the light failure problem is even more serious. In measuring the life of the led, only the damage of the lamp as the end of the life of the LED is far from enough, should be led to the light attenuation percentage to specify the life of the led, such as 35%, it makes more sense.

Using the latest led dimming power source technology, digital design, saving up to 70%, 12W led dimming power supply is equivalent to 40W fluorescent tubes, life expectancy is more than 10 times the ordinary lamp, almost maintenance-free , do not need to change the lamp frequently.

Green environmental protection semiconductor light source, soft light, pure spectrum, is conducive to the user's vision protection and good health, led dimming power supply 6000K cold light gives people a visual cool feeling, user-friendly illumination difference design, more help Focus on the spirit and increase efficiency.
