节能灯维修（Energy-saving lamp maintenance） Circuit diagram and maintenance of electronic energy-saving lamps Circuit diagram and maintenance of electronic energy-saving lamps 8 electronic energy-saving lamp with low voltage starting, no flicker, no noise, high efficiency and energy saving, on the instant bright, long service life (more than 3000 hours, ordinary incandescent 3 times) and other advantages, is welcomed by consumers (especially in the power supply voltage fluctuation area). Electronic energy saving lamp has glass cover type and exposed type. Glass cover and ball ball type, column type, process type three series, the first two series were all transparent, carved, carved and milky white color 4 varieties. The utility model has the advantages of beautiful appearance, uneasy to damage the lamp tube and collision resistance when mounted, etc. The Naked type has H type, UH type, 3U type, 4U type, 2D type and spiral type and so on. According to the color of light, can be divided into red, green, blue and yellow (color temperature is 2700K, is a warm light, similar to incandescent light) and white (color temperature to 6400K mostly, a cold light, similar to the color of the fluorescent lamp); and the color temperature is 5000K the lamp because color is close to natural light, no irritation to the eyes, is more suitable for students and fine work. The electronic energy-saving lamp circuit described in this paper is shown in Figure 1, and the printed board is shown in figure 2. The circuit has been added with soft start (filament preheating) circuit, which can prolong the life of the tube. More and more used in the eye protection lamp and export lamps. Maintenance of electronic energy-saving lamps, first of all to eliminate false faults. After the lights are turned off, the energy-saving lamp has a gap flash, which is not the quality problem of the lamp. The main reason is that the installation of electrical wiring is not standard, the switch is located in the zero li
