energy saving led bulb

LED down light application Because of the fluorescent LED light powder prices associated with pollution problems of the traditional energy-saving lamps, LED quickly enter lighting applications, and as an important member of the LED lighting family, LED down light upstart gradual shift from LED bulb high-end applications for the mass market darling.Since entering the market, LED down lights in engineering lighting, indoor lighting has been large-scale application. Traditional down lights has basically been replaced, in commercial lighting, LED down light has a very high utilization. And because LED down lights production process is simple, relatively low-tech, leading large-scale manufacturers involve, which also lead to the LED down lights produced are uneven, prices is confusion. LED down lights has the old-fashioned features, its advantages place is projecteur extérieur led easy to maintain, more energy, small heat and long service life. Installation is also very convenient, so is widely used in office buildings, shopping malls, supermarkets, hospitals, hotels and so on. With the development of LED lighting industry, chip prices continue to decline and manufacturing technology is improved, the development of LED down lights in commercial areas also continue to have a more solid foundation. LED down lights has simple structure; there is a major component of the lamp body shell, power supply, LED lamp beads. Currently lamp beads basically use 1W lamp beads, compared in small power bead, 1W lamp beads in addition to the external brightness; light intensity is also good enough. Because LED down lights is generally used for indoor ceiling lighting, the floors height is basically 3-5 meters. So high-power lamp beads and now COB integrated light source is the ideal choice. How to reduce the LED switching power supply interference?1, the filteringOne of the main purposes of the EMI filter is to get higher insertion loss in the frequency range of 150 kHz ~ 30MHz, but not attenuate the 50Hz frequency signal, so that the rated voltage, current can pass, but spot exterieur led also must meet certain size requirements. 2, PCB designPCB anti-jamming design includes PCB layout, wiring and grounding, which aims to reduce crosstalk and electromagnetic radiation on the PCB circuits. myledgrowupanty 141104
