Recently, LED lighting products have appeared in a supermarket and appliance store in Shenzhen, and the price is cheaper than the industry expects earlier. The single price is only 50 yuan. At the same time, according to the planning of the Guangdong Provincial Government, the province's purchase of LED lights in the future is expected to receive 30%-50% subsidies. Can LED lights be quickly spread by wind and waves? In addition, how is the energy saving effect of LED lights, is it cost-effective to buy now?
Is it worthwhile to buy a lamp for 50 yuan? In the past, LED lighting was mainly based on products such as flashlights. Recently, in the store in Shenzhen, several LED bulbs with ordinary household threaded mouths were quietly placed on the shelves. This "Thai and Fa" brand of light bulbs, the appearance of a circular plastic body, is the same as ordinary incandescent lamps, but it consists of dozens of small LED illuminators, the package is marked with a rated voltage of 220V/50Hz, The input power is 4.5W, and the brightness is equivalent to 20 watts of ordinary energy-saving lamps and 60 watts of ordinary incandescent lamps.
A salesperson named Zhao said that the "Thai and Fa" LED bulb has been on the shelves for a long time. There are many people who are curious to look up, but not many people buy it. It is understood that the price of this product is 50 yuan, 10 times the same brightness incandescent lamp, 3 times the ordinary energy-saving lamp. However, the advantages of LED lights are quite obvious. It is understood that the energy saving effect of LED lights is very obvious, which can convert 90% of electric energy into visible light, while 80% of ordinary incandescent electric energy is converted into heat energy, and only 20% of electric energy is converted into light energy. Manufacturers claim that the former is more energy-efficient than the latter. More than 90. Moreover, the LED lamp is driven by DC, which does not produce flicker like ordinary energy-saving lamps, and can protect vision, which is undoubtedly a major trend in future lighting.
