Description

Electronic power-ceonomizer for fluorescent lamps

The utility model belongs to the electric energy-saving technical field, specifically a kind of Electronic energy saver that makes fluorescent lamp become the light economize on electricity.

Fluorescent tube is the arc discharge tube that fills low pressure argon gas and mercuryvapour in a kind of, the fluorescent material on the r radiation excitation lamp tube wall that sends during gas discharge in the pipe and luminous.Have inductive and negative resistance charactertistic during the energising of this fluorescent tube, the fluorescent tube of various models all has the highest optimum operation electrical quantity and the necessary startup electrical quantity of a luminous luminous flux and the luminous efficiency ratio of fluorescent tube power consumption (the luminous luminous flux with).During with inductive type ballast and starter relay startup work, all the glow current value than the best is big for the electric current by fluorescent tube, if change the structural parameters of ballast, to reduce the operating current of fluorescent tube, is unfavorable for the fluorescent lamp starter so again.

The purpose of this utility model provides a kind of fluorescence lamp electronic energy-saving appliance that makes fluorescent tube become light and cancellation starter.

The purpose of this utility model is achieved in that it includes a bridge circuit, it is characterized in that being parallel with two electric capacity at least at input one end points of bridge circuit, is provided with a dimmer switch in parallel connection place of electric capacity; Be parallel with the electric capacity of two series connection at the bridge circuit output, between the electric capacity of two series connection, be connected with another end points of input.Shunt capacitance before the rectification bridge circuit plays metering function to entire circuit, behind the electric capacity of a parallel branch of dimmer switch cut-out, strengthens metering function, reduces the lamp works electric current, reaches the effect that becomes light.By two electric capacity that are in series of bridge circuit dc output end, mid point is connected with arbitrary ac input end of bridge circuit, constitutes voltage doubling rectifing circuit.The high pressure that multiplication of voltage is obtained makes its stable state that is operated in less electric current by the former inductive type ballast of connecting with fluorescent tube to the fluorescent tube ballast to fluorescent tube cold start-up under little electric current behind the lamp lighting-up, to realize purpose of saving.

The utility model is because at original inductive type ballast and cancelled starter, keeping even surpassing under the condition of original luminous flux, selected the optimum operation electrical quantity of fluorescent tube, therefore has following advantage: improved luminous efficiency, about energy-conservation 25-30%, improve the power factor of former ballast, reduce apparent power; Starting characteristic is good, increased substantially toggle speed, flicker free phenomenon during build-up of luminance, and starting current is little, work to other electrical equipment is noiseless, has enlarged the temperature range of build-up of luminance, normally starts in the fluctuation range of line voltage 180-240V, still can build-up of luminance to gastight fracture of wire fluorescent tube, and normal luminous work; Equipped common pulling switch can make fluorescent tube become light to be applicable to different illumination needs, can make it in low illumination, and the work down of the power rating of 15W is to reach its energy-saving effect.Advantages such as it is simple to the utlity model has electronic circuit, and electronic component is few, with low cost, safe and reliable to operation, and stable performance is easy to make, damages the back and repairs easily, and volume is little, and is in light weight.

The utility model is described in further detail by specific embodiment below in conjunction with accompanying drawing.

Fig. 1 is a circuit interconnect pattern of the present utility model.

By shown in Figure 1, input at D1, D2, D3, D4 diode-bridge circuit links to each other with power supply by a mains switch K, be parallel with two capacitor C 1, C2 at this input one end points, parallel connection place at C1, C2 is provided with a dimmer switch K1, be parallel with capacitor C 3, the C4 of two series connection at the output of bridge circuit, between C3, C4, be connected with another end points of input.During use, when normal when luminous, connect K switch and K1, supply voltage is behind the C1 and C2 capacitance current-limiting of parallel connection, be rectified into the operating voltage of pulse direct current after by D1, D2, D3, D4 diode bridge as the fluorescent tube build-up of luminance, with the primary inductance type ballast ZL further current limliting voltage stabilizing of connecting with fluorescent tube M, make fluorescent tube remain on best operating current and work down with voltage.Lamp lighting-up is that capacitor C 3, the C4 voltage multiplying rectifier by rectification bridge output end produces the enough starting voltages of fluorescent tube, carries out cold build-up of luminance, does not need filament heat of emission electron excitation, thereby has saved the build-up of luminance relay, can prolong burn-out life again.Its multiplication of voltage process is: when the positive half cycle of electric current, and the C3 charging, charging current is through D1, C3 telegram in reply source; During negative half period, charging current is through C4, D2 telegram in reply source.When change light is luminous, disconnect K, C2 electric capacity and C1 are disconnected, thereby reduce the current limiting capacitance capacity, fluorescent tube is worked under 1/3 running current, its build-up of luminance and multiplication of voltage process are the same.
