LED (semiconductor lighting) energy-saving lamps not only have high brightness and long life, but also save energy by about 40 compared with ordinary energy-saving fluorescent lamps. In an ideal environment, a 1 watt LED energy-saving lamp is equivalent to a 5 watt energy-saving fluorescent lamp and a 10 watt incandescent lamp, which has the highest energy efficiency.
LED energy-saving lamps are extended from landscape lighting to functional lighting, and it is a general trend to enter the home from the outside. Zhang Yusen, general manager of Shijiazhuang Warwick Kaide Technology Development Co., Ltd. said that the long life and fast response of LED lamps are also very suitable for intelligent applications. For example, LED corridor lights, night lights, stair lights, etc. controlled by infrared rays are not very convenient for clapping, licking, coughing.
Recently, the reporter found that many home lighting products such as Shilihe, Ruifeng International, and Wanjia Denghuo in Beijing found that LED home lighting products began to flood into the lighting market. The high price of LED lights affects consumers' desire to buy. A dealer in Beijing Wanjia Lighting City said that, for example, in the market in Beijing, 3 watt LED lamps are priced at 20 yuan, 7 watts are soaring to 90 yuan; and energy-saving fluorescent lamps are usually available for about 10 yuan. Incandescent lamps cost only 1 yuan.
At present, LED lighting is not suitable for main lighting. Mr. Liu, a Beijing citizen who used LED ceiling lamps, said that the LED lights are indeed energy-saving and environmentally friendly, but they are too bright and too dazzling, and they have to change back to ordinary energy-saving lamps.
At present, there are still some problems in domestic LED home lighting. First, the problem of heat dissipation, the current domestic process uses aluminum heat sinks. If the heat sink is not tightly attached to the LED chip, it will affect the life of the LED lamp. Second, the brightness adjustment problem requires a controller. adjust. Zhao Wei, vice president of Beijing Patriot New Energy Technology Development Co., Ltd., said that if domestic enterprises only care about the staking, and do not focus on technology research and development and meet market demand, LED energy-saving lamps can hardly enter the home market.
