In a commercial building environment, there are many opportunities to save energy. In addition to the advantages of efficient lighting, long life, and low maintenance costs, most of the most noticeable is that most of the lighting fixtures using solid-state light sources can greatly reduce energy consumption, the most worth mentioning is LED. In order to emphasize this argument, after three years of relatively slow growth, in fact, in the past two years, the probability of using LEDs in the market has shown a double-digit increase, especially in fixed-position applications, such as architectural lighting. Â Â Â Â The US Department of Energy estimates that if LEDs become the standard technology for indoor white-light small-scale market applications, then 108 kWh of electricity per year can be saved. According to US data analysis in 2007, it is equivalent to saving 1.1% of total annual primary energy. Consumption, and 13% of the electrical energy used for lighting. Â Â Â Â However, despite the other compelling advantages of LEDs, one problem that hinders the development of LEDs is that the drive circuits of these LED devices must have the ability to convert from alternating current to direct current to achieve alternating current (AC) distribution (usually The 227V AC is converted to low voltage direct current (DC). Although this process is fairly simple, it adds cost and reduces the extra conversion efficiency that LEDs produce elsewhere. In view of today's typical building AC distribution facilities, there are no other options. Easy Electronic Technology Co.,Ltd , https://www.yxpcelectronicgroups.com
