Abstract
The utility model relates to an electronic drive for a fluorescent lamp, which is a novel ballasting starter used for a fluorescent lamp. The electronic drive for a fluorescent lamp is formed in a method that diodes D1, D2 are arranged on an input terminal A terminal; a capacitor C4 and the D1 are connected in series, and the D1, capacitors C1, C2, a diode D3 and the D1 are connected in series; after the diodes D3, D4 are connected in series, the diodes D3, D4 are connected in parallel with the capacitor C3. The voltage of the electronic starter for a fluorescent lamp and the current of the electronic starter for a fluorescent lamp are the same during the start moment and at the time of normal operation; as a consequence, the utility model has the advantages of rapid start, stability, electrical energy saving and the extended service life of a lamp tube.
Description
The utility model relates to a kind of novel ballast glow-starter that is used for fluorescent lamp---electronic fluorescent lamp driver.
The electric ballast of Xiao Shouing adopts compositions such as diode, triode and oscillator coil in the market, and majority is to utilize vibration to produce high-frequency ac pulse preheating filament, lights fluorescent tube.And the filament that broken, the fluorescent tube that vacuum degree is good just can not be lighted, the cost height, and price is more than 24 yuan, complex structure, failure rate height.
The purpose of this utility model is to overcome above-mentioned defective to adopt novel unique electronic circuit, directly utilizes civil power by electric capacity, the diode point pipe of lighting a lamp.
Technical solution of the present utility model: electronic fluorescent lamp driver, negative terminal and crystal diode D2 anode by crystal diode D1 join, the D2 negative terminal joins by capacitor C 4 and crystal diode negative terminal, D1 anode, the negative terminal of D1 joins by the anode of capacitor C 1, C2 and D3 and the negative terminal of crystal diode D4, the anode of D3 and D4 negative terminal join, the D4 anode joins by the negative terminal of capacitor C 3 with D3, the positive termination load (fluorescent lamp) of the negative terminal of D2, D4, A, B are two inputs of alternating current 220V, A termination D1 anode, B terminates between C1, C2.
Accompanying drawing is an electrical schematic diagram of the present utility model.
Operation principle is such, and circuit is connected behind the 220V power supply by D1, C1, C2, D2, D3, D4 and produced pulsating voltage at an alternation simultaneously to C3, and the C4 charging forms at fluorescent tube two interpolars and to impact electric arc and start fluorescent lamp work.Electric current and voltage during with operate as normal is the same to the utility model in the moment that starts.Thereby starter is stable rapidly, and power saving can prolonging lamp tube service life.Novel unique electronic circuit directly utilizes civil power by electric capacity, the diode point pipe of lighting a lamp.Circuit is simple, and degree of reliability was applicable to various fluorescent lamps greater than 10000 hours.Even filament has broken,, just can continue to use as long as vacuum degree is good.Cost is low, 17～19 yuan of prices.Startability is good, and fault is few, and power savings is obvious, and low pressure 110～120V can start.
