What is the maintenance of the electronic ballast for the energy-saving lamps and the schematics of the circuit diagram?
Can adjust L's inductance or C2's electrical capacity, make it not interfere with remote control TV, and can work safely. Fourth, use energy-saving lamps to notice matters The energy-saving lamp cannot be used in the circuit of dimming lamp, delay switch, induction switch. Avoid using in high-temperature, high-humidity environments. Electronic energy-saving lamps are like other lamps and lanterns, should not be opened and closed frequently.
Energy-saving lamp electronic ballast is replace inductive rectifier products, its characteristic is to use two 13003 amplification, each other is a filament for 120 volts, in the middle of the two filament series a 0.01 UF ceramic tile capacitance, make its light. Thank you to adopt
The electronic energy-saving lamp has a type and bare type. There are three series, such as ball, ball and craft, and the first two series are all transparent, engraved, colorful and ivory. It has beautiful appearance, easy to install and not easy to damage the lamp tube, and the collision and so on. The exposed type is H, UH, 3U, 4U, 2D and spiral. According to the luminous color points, can be divided into red, green, blue, yellow (color temperature is 2700 k, belongs to the warm color light, similar to the incandescent light color), white (the majority with 6400 k color temperature, and belong to cool color light, similar to the fluorescent light color); And the lamp of color temperature is 5000K because light color is close to natural light, have no stimulation to the eye, suit the student and meticulous work more. The electronic energy-saving lamp circuit shown in this paper is shown in figure 1, and the chart is shown in figure 2. The circuit has been added with soft start (filament preheating) circuit, which can extend the life of the lamp. It is applied to the lamp and the exterior pin lamp
If C1, Q1, and Q2 are in good condition, the D1 ~ D4 will have to be routinely checked and pressure-resistant. Or substitute D1 ~ D4 all in the best quality. The D1 ~ D4 and C1 should be replaced by the D1 ~ D4 and C1 burst. Only the resistance and triode on the Q2 side will be burned, and the key to check that C2 has been punctured. If the high frequency transformer B is damaged, it can be made on a high frequency magnetic loop of 10mm by 6mm by 5mm, which is on a high frequency magnetic loop of 10mm x 6mm by 5mm. T3 is 8 laps (note the end of the head). Choke coil L: lamp tube power 5 ~ 40W, corresponding to 1.5 ~ 5.5 mH.
