The lamp operating temperature is an important parameter. You might think, as long as you do not touch it when the lights work, will not be scalded, the high temperature makes no big adverse effect on us, which is not. First, according to the law of conservation of energy , the more calorie the lighting issues, the more energy wasted in heat there will be, the less light is turn into what we need, which means energy conversion efficiency of the light is low, causing more waste of resources. Second, the temperature will increase the operating ambient temperature of the lamp, affecting the life of lamps, making negative effect on the lamps, so the temperature can be controlled at a lower level that lighting is more suitable for our use. The current sink of the LED bulb lights have mainly two distinct structure: smooth surface of the radiator and the cooling fins. We firstly test these two different cooling structure, and then compare with fluorescent lamps (CFL) The shape of the radiator having smooth surface without special treatment, relying solely on the heat sink and contact surfaces for cooling air, this material has the advantage of using less material and relative low processing cost; the outer surface of the radiator using the fin structure is formed by the fin-shaped unevenness, so the advantage is that the surface area of radiator is lager ,which means that the area contacting with the air is larger, in theory, the better cooling effect can be obtained. LED lights indicate temperature test This test uses Fluke (Fluke) Ti25 Thermal Imager specialized equipment to test the temperature, its thermal sensitivity is = 0.1 degrees Celsius, using the latest IR-Fusion ™ technology, which fuses the infrared and visible light images so that can faster and more accurately test the test temperature. In order to understand radiator cooling effect of these two different LED lights, we removed two kinds of LED lamp shade, both lights LED temperature and heat sink temperature conditions were tested. If the temperature of heat sink is small difference with LED temperature, what can be considered that the heat sink is better; On the contrary, which means that the heat sink can not dissipate the heat very well. What can be seen that the temperature of the LED whose heat sink adopting smooth surface rises quickly, but the temperature of the heat sink rise more slowly, the temperature difference is about 23 degrees after stable; the temperature of LED using fins rise slowly, the temperature of cooling fins rise significantly faster, the temperature difference after both are base stabilized is about 15 degrees Celsius. Through the above test we can seen, the LED lamp adopting cooling fins can better control temperature, on the whole, there is no significant difference in temperature. Lead lighting adopts high quality cooling fins to ensure LED lights such as LED flood light, LED tunnel lights working outdoor for long hours generate less heat relative to high-pressure mercury lamp, if you want to know more LED floodlight please click www.lead-lighting.com/products/bid19-1.htm or select home page to learn more about LED lighting.
