Abstract
The utility model relates to a novel electronic ballast, which comprises a lamp holder, two diodes, three capacitors, a power switch, a brightness control switch and the like. The utility model utilizes the voltage doubling rectifying circuit composed of the diode and the capacitor to boost the voltage, so that the lamp tube is punctured to emit light; and a capacitor can be additionally connected by using the brightness control switch, thereby controlling the brightness of the lamp tube. The utility model has the advantages of fast start, wide voltage application range, difficult blackening of the two ends of the lamp tube and prolonged service life of the lamp tube; and the circuit is simple, the cost is low, the safety and the energy conservation are realized, the durability and the reliability are realized, and the fluorescent lamp is particularly suitable for being matched with a 3W fluorescent lamp.
Description
The utility model relates to a kind of ballast, particularly a kind of novel electron ballast.
In the prior art, a lot of electric ballasts are arranged, but its complex circuit damage easily, and cost is higher.
The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part and provides a kind of circuit simple, and is with low cost, the novel electron ballast of superior performance.
The purpose of this utility model can reach by following measure: the utility model comprises lamp holder, fluorescent tube, it is characterized in that: also have a voltage doubling rectifing circuit of being made up of diode D1, D2, capacitor C 1, C2, D1 and D2 join, and C1 and C2 join, D1 and C1 join, and D2 and C2 join.
The purpose of this utility model can also reach by following measure: also can be connected in series a brilliance control K switch 2 and capacitor C 3 at ac power input end.Capacitor C 1, C2, D1, D2 are contained in the lamp holder.
Fig. 1 is an electrical schematic diagram of the present utility model;
Fig. 2 is a contour structures schematic diagram of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):
With reference to Fig. 1, Fig. 2, the utility model is made up of lamp holder 1, fluorescent tube 2, diode D1, D2 capacitor C 1, C2, C3, mains switch K1, brilliance control K switch 2 etc.Capacitor C 1, C2 diode D1, D2 etc. form a voltage doubling rectifing circuit, when the K1 that closes a switch, K2,～220V input power supply is raised to the output voltage of about 400～600V behind D1, D2, C1, C2 voltage multiplying rectifier, and is added on the filament of fluorescent tube 2, and it is luminous to make that fluorescent tube 2 punctures.The wattage of fluorescent tube 2 is generally 3 watts (also can be the fluorescent tube of other wattages, the parameter of D1, D2, C1, C2 will change at this moment), and fluorescent tube 2 can be annular lamp tube or straight fluorescent tube.When needs are regulated lighting tube brightness, can disconnect K2, this moment, alternating current input power supplying will just be delivered to voltage doubling rectifing circuit through behind the C3, so the voltage that voltage doubling rectifing circuit is exported is higher, made the brightness of fluorescent tube 2 brighter, and other equally can light by the broken fluorescent tube of filament.
Among Fig. 2, lamp holder 1 is 3 watts of general fluorescent lamp lamp holders, and devices such as C1, C2, D1, D2 are contained in the lamp holder 1, becoming one structure, and fluorescent tube 2 can be packed in the lamp holder 1 by bayonet socket 3.And mains switch K1, brilliance control K switch 2 generally are contained in the mains switch box body.
The utility model has following advantage compared to existing technology:
1. start soon, voltage is endure in 130V～250V scope, but and the service life of prolonging lamp tube, make its two ends be difficult for blackout.
2. the circuit advantages of simple is with low cost, and energy-saving safe is durable reliable, is particularly suitable for supporting the use with 3 watts of fluorescent lamps.
Claims (3)
1, a kind of novel electron ballast comprises lamp holder 1, fluorescent tube 2, it is characterized in that: also have a voltage doubling rectifing circuit of being made up of diode D1, D2, capacitor C 1, C2, D1 and D2 join, and C1 and C2 join, and D1 and C1 join, and D2 and C2 join.
2, ballast according to claim 1 is characterized in that: also can be connected in series a brilliance control K switch 2 and capacitor C 3 at ac power input end.
3, ballast according to claim 1 is characterized in that: capacitor C 1, C2, D1, D2 are contained in the lamp holder 1.
