Electronic absorb dome light circuit and maintenance circuit

Published:2011/3/30 21:22:00 Author:Jessie | Keyword: absorb dome light, maintenance

AC 220V rectified by the D1 ~ D4, C1, C2 filtering. C1 and C2 are series, can directly supply powertotubes to save charging capacitance, also reduced the compression requirements. R1 is startup resistance, provides BG2 forneeded initial voltage, R2 is bias resistors, BG1, BG2 and L1, L2, L3 compose theoscillating circuit, diodeD5 provides dischargecircuit for C3. L1 and L3 respectively connected to the bases of BG1 and BG2, which makes BG1 and BG2 get positive feedback voltageto initial. So that BG1 and BG2 turn in connected. High-frequency voltage formed in tubeto lighten it.   (View)

In beginning, J inthe state of losing electricity. When using, handle the open, the human body induction signal amplified by BG1 ~BG3, J sucks close, meanwhile J - 1 sucks and make J self-locked. When need to shut off, handle the close, the human body induction signal amplified by BG4 ~BG5, bypass BG2 base current, J release, circuit is back again. When making circuit BG1 ~ BG5's BVceo > 30V, BG1, BG3, BG4, BG5's β>50, BG2's β>80, the unit of capacitance is µF/V. After installeditcan work without debugging. When this switch device shuts off the power, power consumption is close to zero, turn-on'spower < 0.5 W, switch devices using voltage range> 130V ~ 250V.   (View)
