Abstract
The utility model relates to an energy-saving fluorescent lamp socket, which relates to a lighting lamp. The utility model is formed by the way that a filtering capacitor is removed from the inner part of an existing power general illuminating lamp socket, and a tank circuit network is composed of a diode and a capacitor, which is connected with the output end of a rectification circuit. The close time of a wire current is reduced because of the use of the tank circuit network by the lamp socket, and consequently, a power factor is greatly increased. The utility model has the advantages of simple structure and low cost.
Description
The utility model relates to a kind of lighting.
Chinese patent " 89218441.8 " discloses a kind of illuminating lamp of universal power, this light fixture is with filter capacitor, rectification circuit, the frequency conversion parts that inverter circuit is formed are independently made lamp socket, current limiting element, starting element and fluorescent tube attach together the lamp socket that is integral and forms, the lighting of the universal power that fluorescent tube is split type, bring great convenience to user's use, but this lamp socket remains the low problem of power factor.
In view of above-mentioned, the purpose of this utility model aims to provide a kind of High Power Factor power saving fluorescent lamp lamp socket with low cost.
The power saving fluorescent lamp lamp socket that the utility model provides is that the filter capacitor in the former frequency conversion parts is removed, and the accumulator network of being made up of electric capacity and diode in the output connection of rectification circuit forms, and tube load is connected between inverter circuit output and accumulator input.Utilize the accumulator network to reduce the deadline of line current, realization improves the purpose of power factor.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is a kind of physical circuit figure of the present utility model.
Among the figure in the frame of broken lines for containing current limiting element L, the fluorescent tube of starting element C, slightly black line partly is the accumulator network, it is by the capacitor C that is in series
41, C
42, the diode D that is in series
42, capacitor C
43With the diode D that is connected to two series circuit mid points
41The H type circuit network that constitutes, this network and rectification circuit output end A, B links to each other, and fluorescent tube is connected between inverter circuit output C and accumulator input D.
The power frequency civil power is through rectification circuit D
1～D
4After being rectified into direct current, being reverse into high-frequency electrical through inverter circuit again and supplying with fluorescent tube, and the C in the accumulator
41, C
42Be the capacitance of fluorescent tube, again to capacitor C
43Play the effect of charging dividing potential drop, when the power frequency supply instantaneous voltage was higher, high-frequency current passed through D
41To C
43The charging energy storage, when the power frequency supply instantaneous voltage is low, C
43Pass through D
42Release energy, provide DC power supply, make inverter continue operate as normal, guarantee lamp luminescence to inverter.For guaranteeing the fluorescent tube stable start, be preferably in capacitor C
41Two end parallel resistance R
41(as shown in Figure 1).Usually, can be at D
41Seal in voltage stabilizing didoe or resistance in the branch road, so that to playing the fine setting effect deadline of line current.
Because the capacitor C in the accumulator network
43Charging voltage be the high frequency voltage of taking after inversion, when the current potential of accumulator input D is lower than C
43The time, because of D
41Existence, can not be to C
43Charging, institute is so that C
43Charging interval elongate, reduce the deadline of line current, thereby improved power factor.This power saving fluorescent lamp holder structure is simple, with low cost.
