Abstract
The utility model relates to a high efficient electronic starter which has light adjustment function and is mainly composed of a light adjustment current limiting circuit, a voltage doubling rectifying circuit and a bridge rectification filter circuit, and the high efficient electronic starter can adjust light by using variable capacitances. The volume and the weight are reduced because the high efficient electronic starter adopts the circuits which are composed of resistors, capacitances, diodes, etc., and the high efficient electronic starter has no noise and no power consumption and is characterized in that the high efficient electronic starter can also be started with low voltage, in addition, the stroboscopic phenomenon is eliminated so that the vision can be protected by using the DC power supply; the utility model is an ideal lighting tool.
Description
The utility model relates to a kind of electric light plant, the open-minded device of efficent electronic of a kind of energy light modulation of more specifically saying so.
The open-minded circuit of forming by inductance type ballast and bimetal leaf starter of fluorescent lamp now, the structure heaviness, install also inconvenient, simultaneously because inductance type ballast needs silicon steel sheet and copper enamelled wire, cause cost to improve, also have simultaneously low-frequency noise, consume active power, the fluorescent lamp of 40W has the 6W power consumption approximately on ballast.In addition, this kind circuit also has low pressure to be difficult for the shortcoming that starts.
Though also occurred the open-minded circuit of electronics at present, majority is comparatively complicated, and the cost height, and can not realize the continuous adjusting of brightness.
The purpose of this utility model is to have designed the open-minded device of efficent electronic of a kind of energy light modulation in order to overcome above-mentioned the deficiencies in the prior art part.
The purpose of this utility model can realize in the following manner: the open-minded device of a kind of efficent electronic composes in parallel the light modulation current-limiting circuit by resistance and variable capacitance, be connected with voltage doubling rectifing circuit, bridge rectifier filter circuit, give fluorescent lamp direct voltage stably then.
The utlity model has following advantage: this open-minded device has been cancelled traditional starter and ballast, and only uses resistance, electric capacity and diode, and cost reduces greatly, and volume is also very little.And this circuit energy low voltage starting, when voltage 160V, fluorescent lamp still can operate as normal.It has used direct current supply; eliminated stroboscopic phenomenon; help vision protection, simultaneously, can make the fluorescent tube of the filament that broken luminous again; prolonging lamp tube service life is more than 1 times; also eliminated because the noise that ballast sends has been saved the energy, the essentially no power consumption of this circuit; secondly, can realize the continuous adjusting of lamp brightness by variable capacitance easily.
