Abstract
The utility model relates to a digital ballast for a metal halogen lamp, which comprises a circuit part and a mechanical structure part, wherein, the circuit part comprises a voltage doubling rectifying circuit and a voltage regulating resistor R. An output terminal of the voltage doubling rectifying circuit is connected in series with the voltage regulating resistor R and a metal halogen lamp. The utility model has the advantages of simple structure, lower product cost, small volume, small electrical consumption and long service life. The disturbance to an electric network is small.
Description
The utility model is a kind of and Metal halogen lamp steeps matching used electric equipment, replaces traditional Metal halogen lamp Inductive ballast and trigger, is applicable to all Metal halogen lamp bubbles.
At present, Metal halogen lamp ballast on the general market all adopts inductance coil as its ballast element, make that whole Metal halogen lamp ballast volume is big, quality is heavy, price is high, bigger to the interference of electrical network, and circuit part must have trigger, circuit structure is comparatively complicated, the price of entire product is further improved, and power factor is not high, power consumption is bigger.
The purpose of this utility model provides metal halogen lamp electric ballast, and circuit structure has saved trigger and inductance element, and structure is comparatively simple, and product cost is lower, and volume is less, power consumption is little, and is little to Disturbance in Power Net, and life of product is long.
The utility model is realized by following technical scheme: it comprises circuit part and mechanical structure part, and circuit part comprises voltage doubling rectifing circuit and regulating resistor R, the output serial connection regulating resistor R of voltage doubling rectifing circuit and Metal halogen lamp bubble L.
The utility model compared with prior art has following advantage: 1) replace inductance coil as the ballast element with resistance R, volume, the weight of product are reduced greatly, the cost of product is lower, the present cost of Metal halogen lamp ballast of 150W on the current market is about 80 yuan, adopt structure of the present utility model now, cost probably has only about 20 yuan; 2) utilize capacitor C 1, C2 to make the voltage stack produce high pressure and light Metal halogen lamp, simple in structure; 3) design feature of circuit part determine this product power factor greater than 0.95, reduce the loss of electricity, life of product is longer, second harmonic is less than 5, triple-frequency harmonics is less than 15, crest is than less than 1.65; 4) traditional Metal halogen lamp ballast will be used trigger, and circuit structure, product cost are improved greatly, and the utility model does not adopt flip-flop circuit simple in structure, and product cost is lower.
Below in conjunction with accompanying drawing the utility model is done detailed explanation:
Fig. 1 is a circuit part schematic diagram of the present utility model;
The utility model comprises circuit part and mechanical structure part, and circuit part comprises voltage doubling rectifing circuit and regulating resistor R, the output serial connection regulating resistor R of voltage doubling rectifing circuit and Metal halogen lamp bubble L.Voltage doubling rectifing circuit comprises rectifier B and capacitor C 1, C2; The utility model adopts the different resistances of regulating resistor R to cooperate the Metal halogen lamp bubble L of different capacity, and the voltage ratio of debugging Metal halogen lamp bubble L is more convenient, makes control of product quality more stable, and product structure is simple; The design feature of voltage doubling rectifing circuit makes the parameters of product obtain very big improvement.
