Abstract
The utility model relates to an electronic ballast, comprising a voltage multiplying rectifier, an auxiliary starting circuit, and current limit brightness regulating circuit. The brightness of the electronic ballast can be regulated freely. The voltage multiplying rectifier is composed of a diode BG1, a diode BG2, a capacitance C1 and a capacitance C2. The auxiliary starting circuit is composed of a diode BG3, a diode BG4, a capacitance C3 and a capacitance C4. The current limit brightness regulating circuit is composed of a resistor R1 and a potentiometer W1. The utility model has the advantages of simple structure and low cost. Without starters and filament preheating, the service life of lamp tubes is prolonged. The ballast can start normally under a low voltage above 150V, the brightness and power consumption of the lamp tubes can be regulated.
Description
The utility model belongs to electronic technology, is used for the electric ballast of various conventional fluorescent lamps pipes.
The disclosed electric ballast of ZL932102336, the cost height can not light modulation.
The utility model overcomes above-mentioned patent deficiency, is that a kind of cost is low, volume is little, the fluorescent tube long service life, lowly presses that starter, brightness are adjusted arbitrarily, Light modulating type electronic ballast easy to use.
The utility model circuit working schematic diagram, as shown in drawings, it forms the voltage multiplying rectifier starting circuit by diode BG1, BG2, capacitor C 1, C2, BG3, BG4, C3, C4 utilize and exchange the auxiliary starting circuit of high order harmonic component composition, resistance R 1 is a fluorescent tube current-limiting resistance, and potentiometer W1 makes fluorescent tube S continuous light tuning.Change the resistance of potentiometer W1, can make fluorescent tube be fixed on any luminance state, also W1 can be divided into a plurality of resistance, carry out the stepping light modulation, as shown in Figure 2, utilize change over switch respectively each resistance of short circuit reach the purpose of light modulation.
The circuit working principle, AC power AC adds to fluorescent tube S starter through BG3, BG4, R1, W1 again behind BG1, BG2, C1, C2 rectification and voltage multiplier.
The capacity of capacitor C 1, C2 has determined the power of this circuit, and its power is directly proportional with capacity.This circuit each component parameters scope: BG1, BG2, BG3, BG4 are 1N4007 electric current 1A, withstand voltage 700V, capacitor C 1, C2,1.5-6uf, withstand voltage 400V, C3, C4 are 1000pf, withstand voltage 600V, resistance R 1,0.1-0.3K, power 20W, potentiometer W1, resistance is indefinite, adjust according to the brightness needs, power is greater than 20W.R2 is 1K power 20W, and R3 is 2K power 15W, and R4 is 3K power 10W, and R5 is 5K power 5W, and R6 is 20K power 3W.W1 and R1-R5 need use the wire-wound resistor potentiometer.
The utility model, power supply are regardless of the Live line Zero line end, but the above starter of low pressure 150V, the fluorescent tube of the disintegration of filament can normally use, and lamp tube ends is not turned black, and in the useful life of prolonging lamp tube, lighting tube brightness and power consumption 1-50W adjust arbitrarily.
