LED spotlights are mainly composed of housing, lamp beads, aluminum base plate, and drivers. The specific analysis is as follows:
LED spotlight shell: baking varnish, electroplating two kinds of shells. The whole set includes lamp cover, lamp cup, base, aluminum substrate, lens, screw. Suitable for MR16, GU10 lotus shape, beautiful and generous. Good heat dissipation performance.
LED spotlight lamp beads: six-pin RGB, dedicated for spotlights, red light: 40lm, green light: 60lm, blue light: 15lm, both use 350 mA current
LED spotlight driver:
Universal input voltage (220V) and constant current output to ensure the safety of high-power LEDs. High power factor, greater than 0.98 or more. Isolated power supply with over-temperature protection, short-circuit protection, and open-circuit protection can drive all 3W LEDs (including red and yellow). Ceramic capacitors, long-life design, high reliability up to 50,000 hours.
1. Conventional method
Using ordinary thermal pads to dissipate heat for LED spotlights, the thermal conductivity is average,
2. Liquid heat dissipation
Foshan Zhongnan Semiconductor Lighting Research Institute has researched and invented a liquid heat dissipation method to successfully solve the heat problem of high-power LEDs and the heat dissipation problem of small-size LED spotlights. It has made a historic breakthrough and contributed to the problem of difficult heat dissipation of LED spotlights.
3. Heat pipe cooling
Using heat pipes to dissipate heat for LED spotlights, just like computer CPU heat pipes to dissipate heat, so the volume becomes larger and more bulky.
