However, it will cost a lot and take a long time to transform the original fluorescent lighting system into LED lighting (such as the lighting system of a subway station or a waiting hall). New LED lighting power supply system needs to be more complex than the traditional lighting power supply system, the cost is much higher, if there is no policy support and economic support is difficult to succeed. The application of LED lamp is a comprehensive technology application, it involves LED, solar cell, battery, AC/DC converter, LED driver and other fields of technology. But the key technical problem is that LED's luminous efficiency is not high enough and production cost is not low enough. It may be years before LEDS reach homes.\n\nCommon-Cathode CC <a href=\"http://www.lanpade.com/7-segment-led-dot-matrix/3014ab.html\" style=\"color: #333;\">3014AB</a> 7-Segment digit <a href=\"http://www.xlitx.com/datasheet/3014AB.pdf\" style=\"color: #333;\">3014AB</a> LED Common-Anode CA <a href=\"http://www.lanpade.com/7-segment-led-dot-matrix/3014bb.html\" style=\"color: #333;\">3014BB</a> Display <a href=\"http://www.xlitx.com/datasheet/3014BB.pdf\" style=\"color: #333;\">3014BB</a> 0.30 inch\nCommon-Cathode CC <a href=\"http://www.lanpade.com/7-segment-led-dot-matrix/3104agg.html\" style=\"color: #333;\">3104AGG</a> 7-Segment digit <a href=\"http://www.xlitx.com/datasheet/3104AGG.pdf\" style=\"color: #333;\">3104AGG</a> LED Common-Anode CA <a href=\"http://www.lanpade.com/7-segment-led-dot-matrix/3104bgg.html\" style=\"color: #333;\">3104BGG</a> Display <a href=\"http://www.xlitx.com/datasheet/3104BGG.pdf\" style=\"color: #333;\">3104BGG</a> 0.30 inch\n\n<hr style=\"border:1px solid;\">\n\n<a href=\"https://gingkoapp.com/the-unit-price-of-1w-white-led.html\" style=\"color: #333;\">The unit price of 1W white LED</a>\n<a href=\"https://gingkoapp.com/home-applications-of-led-lighting.html\" style=\"color: #333;\">Home applications of LED lighting</a>\n<a href=\"https://gingkoapp.com/12v-and-24v-led-lamp-application.html\" style=\"color: #333;\">12V and 24V LED lamp application</a>\n<a href=\"https://gingkoapp.com/led-lighting-power-supply-system-is-complex.html\" style=\"color: #333;\">LED lighting power supply system is complex</a>\n<a href=\"https://gingkoapp.com/chinese-lighting-market-is-huge.html\" style=\"color: #333;\">Chinese lighting market is huge</a>\n<a href=\"https://gingkoapp.com/color-and-brightness-of-led-in-different-occasions.html\" style=\"color: #333;\">Color and brightness of LED in different occasions</a>\n<a href=\"https://gingkoapp.com/leds-luminous-intensity-unit-is-candela.html\" style=\"color: #333;\">Leds Luminous Intensity Unit is Candela</a>\n<a href=\"https://gingkoapp.com/led-luminous-flux-in-unit-of-lumen.html\" style=\"color: #333;\">LED luminous flux in unit of Lumen</a>\n<a href=\"https://gingkoapp.com/led-luminance-refers-to-the-light-intensity-density.html\" style=\"color: #333;\">LED Luminance refers to the light intensity density</a>\n<a href=\"https://gingkoapp.com/the-color-rendering-of-led-may-be-different.html\" style=\"color: #333;\">The color rendering of LED may be different</a>"}],"tree":{"_id":"2671e964330c0554e4000036","name":"LED lighting power supply system is complex","publicUrl":"led-lighting-power-supply-system-is-complex"}}
