[Pu Wan heat Technology - industry, academia, research, sales of body LED bulb manufacturer, to build China's high-tech entrepreneurs in the green low-carbon environmental quality LED bulb, high heat, high insulation, low density, high Performance | is the benchmark for similar products business enterprise! Cooling Kit truly first brand! ! ! ] Second, from the market price for the white power LED. In high power LED or an aristocratic white products, high-power products because the price is still too high, thermal plastic LED lamp cup and technically still need to be improved, so that high-power white LED products are not who wants to use it can be used . Below to decompose under high-power LED heat related issues. Plastic led lamp cup is called the fourth generation light source or green light, energy saving, environmental protection, long life, small size and other characteristics, can be widely applied in various directions, display, decoration, backlight, general lighting and urban night scene fields. In recent years, the brand LED bulb, some of the world's economically developed countries around the development of LED technology in a fierce competition. [Pu Wan heat Technology - industry, academia, research, sales for the body, is committed to building China green carbon environmentally friendly high-tech entrepreneurs, high heat dissipation, high insulation, low-density, high-performance | is the benchmark for similar products in the enterprise business ! Cooling Kit truly first brand! ! ! ] Now I do not say the company selling the product or brand is best, but I can recommend how you look at what makes a good! First, look at the brightness. Wattage incandescent usually talk without speaking lumen LED bulb, LED bulb though it can be used to count the wattage, but the LED light effect in constant development, wattage and do not represent the number of lumens. I used several watt incandescent generally divided into 15W, 30W, 45W, 60W, 75W, 100W and so on. If you do change the incandescent lamp lumens to calculate the luminous efficiency of incandescent lamps in 7.5-12lm / W. The higher the wattage the greater the efficiency. Specific incandescent bulb and LED power conversion as follows: 3 * 1WLED bulb instead of the actual power of about 4-4.5W = 12W = 30W CFL about about 5 * 1WLED incandescent bulb actual power in 6 about -6.5W around instead of = 20W incandescent 45W CFL = about 7 * 1WLED bulb instead of the actual power of about 8-8.5W = 30W = 75W CFL about about brand LED incandescent bulb, Cape square cooling Technology (online consultation), enterprises stone LED bulb provided by the Dongguan City, Pu Yi million Optoelectronics Technology Co., Ltd. heat.
