[Prior Art] Yiming lamps are mostly based on fluorescent lamps. The service life of Riken is short and the brightness of bribery is not very sufficient. g-scales often need to use higher wattage fluorescent lamps or increase the number of fluorescent lamps. To increase the brightness of the lighting, so that the overall power consumption increases. After the invention of the LED lamp, compared with the fluorescent lamp, the utility model has the characteristics of low power consumption, low heat generation, long service life, fast starting speed, rich color and good brightness, and can save a lot of power consumption. Therefore, the Lai Ming lamps used in the '7 family towels, which have been increasingly valued in environmental protection concepts, have been gradually converted from fluorescent lamps to LED lamps.
