Abstract

The utility model relates to a multipurpose energy saving electronic ballast comprising a voltage doubling rectification circuit composed of diodes D1, D2, D3, D4 and capacitors C3, C4, a filter current limiting and stabilization circuit composed of capacitors C1, C2, R3, R4, and a release circuit composed of resistors R1, R2. The utility model has the advantages of simple circuit, low cost, stable performance, energy saving by more than 30 percent, normal lighting after a filament light tube is burned out, glow starting under low voltage of 100 volts, freedom from flicker and interference.

Description

Use high energy-saving electronic ballast more

The utility model belongs to ballast, especially a kind of high energy-saving electronic ballasts of using more.

Have the high-frequency electronic oscillatory type electric ballast of the commercially available board TD-5B type of rising now, have the production cost height, stability is poor, and repair rate is higher.Old-fashioned inductance type ballast power consumption is big, and low pressure can not starter, has other electrical equipment of interference to flash phenomenon during starter.

The purpose of this utility model is to provide a kind of circuit structure simple, performance voltage stabilizing, energy-conservation, and low-voltage starter makes to burn out normally luminous electric ballast of fracture of wire light pipe.

Technical solution scheme of the present utility model is such, constitutes voltage doubling rectifing circuit by diode and electric capacity, constitutes filtering, current limliting, current stabilization circuit by electric capacity, resistance, constitutes the release circuit by resistance.This ballast produces high direct voltage and directly is added to the light pipe two ends, makes vaporized mercury, and it is luminous to produce the ionization conduction.

The utility model advantage is simple, the stable performance of circuit, 100 volts energy of low pressure starter, flicker free, noiseless, make burn out the fracture of wire light pipe can be normally luminous, energy-conservation more than 30%, low cost of manufacture

Below in conjunction with drawings and Examples to the utility model further instruction.

Accompanying drawing is a structure electrical schematic diagram of the present utility model.

In the electrical schematic diagram shown in the drawings, voltage doubling rectifing circuit is by two pipe utmost point D₁、 D ₃, capacitor C₃、C ₄、D ₄、D ₂Serial connection forms, filtering, current limiting capacitance C₁、C ₂After the serial connection, C₁Positive pole meets D₁、D ₃、C ₂Negative pole meets D₄、D ₂, ballast resistance R₃、R ₄In the sequential circuit, the resistance R of release circuit₁Connect capacitor C₁、C ₂，R ₂Connect C₃、C ₄ Capacitor C 1, C2 are 1.5 μ F-3.5 μ F, withstand voltage 250 volts, C₃C ₄Be 0.4 μ F-1 μ F, withstand voltage 630 volts, diode D₁-D ₄Be IN4007.

Operation principle: behind the plugged voltage, D1 when the power supply lower end is positive half cycle Conducting, the C1 charging, D2 conducting when negative half period, the C2 charging (is charged to the power supply peak value Voltage), receive lamp tube ends after C1, the C2 series connection, so lamp tube ends voltage Near 2 * 2 times (near 600V) of supply voltage, thereby fluorescent tube can be punctured, The fluorescent tube internal resistance reduces after starting, and the rectification load increases the weight of, and the output direct current drops to operating voltage, After the fluorescent lamp normal operation, C1, C2 play metering function, for overcoming scintillation Circuit seals in R3, R4 current stabilization. Electric current passes through D when the power supply upper end is positive half cycle 3 to the C3 charging, is charged to 2 times of supply voltages, when the power supply lower end is positive half cycle, Electric current charges to C4 by D4, and the voltage on C3 and the C4 just is to fluorescent tube To series connection, thereby be added on the fluorescent tube DC voltage near power supply by R3, R4 Twice impels fluorescent tube to light.

Embodiment: with reference to accompanying drawing, the parameter of capacitor C 1-C4 is to decide according to the wattage difference of light pipe, general employing capacitor C 1, C2 are 1.5-3.5 μ F, withstand voltage 250 volts, C3, C4 are 0.47 μ F-1 μ F, and withstand voltage 630 volts, resistance R 1, R2 are 1M1/2W, R3, R4 are 47 Ω, and diode D1-D4 is IN4007.Element among the figure is welded on the circuit board, and is fixed in the can, connect 220 volts of power supplys from resistance R 1 two ends lead-in wire, R3, R4 lead-in wire connects light pipe two ends filament.
