Abstract
The utility model discloses an electric-economizing device for incandescent lamp. Though the device is designed to avoid the impact of surge current and excess voltage to the incandescent lamp and has the character of low dissipation of energy and the capacity of extending the service life of the lamp, the utility model is actually formed by the connection of an electronic switching circuit, a triggering delay circuit, a variable internal resistance circuit and a power sense circuit. Thus the device has the advantages of stable and reliable performance and better effects.
Description
The utility model belongs to electronic equipment and makes the field.
Prior art in the utility model prior art field is: ordinary incandescent lamp, this lamp directly connect 220 volts of power supplys makes the crow silk in the bulb shinny, thereby existence is subjected to the drawback that surge current impacts, power consumption is high.
Purpose of design of the present utility model is: at the weak point of above-mentioned existence, design a kind of incandescent lamp electricity-saving appliance of avoiding that surge current impacts, power consumption is low and making the incandescent lamp life-saving.
Design of the present utility model is: the incandescent lamp electricity-saving appliance is made up of electronic switching circuit 1, triggering delay circuit 2, variable interior resistance circuit 3 and over-voltage detection circuit 4, and its electronic switching circuit is made up of the controllable silicon SCR 1 that is attempted by the bridge rectifier output; Triggering delay circuit is made up of resistance R 1, R2, R3 and electrochemical capacitor C1 connection; The end of R2 and R3 connects with the trigger electrode of controllable silicon SCR 1, and the other end of R2 connects with the end of R1 and the positive pole of C1, and the other end of R3 connects with the positive pole of D3, D4 and the negative pole of C1, and the other end of R1 connects with the negative pole of D1, D2; Resistance circuit is made up of resistance R 4 and triode BG1 in variable, and the end of R4 connects with the collector electrode of BG1, and the other end connects with the positive pole of C1, and the emitter of BG1 then connects with the negative pole of C1; Over-voltage detection circuit is made up of diode D5, resistance R 5, W1 and electrochemical capacitor C2, the end of the positive pole of its C2 and W1 connects with the base stage of BG1, the other end connects with the collector electrode of BG1, D5 and R5 coupled in series, the end of R5 connects with the base stage of BG1, the positive pole of D5 connects with load, and the adjustable end of resistance W1 connects with the negative pole of electrochemical capacitor C2.Power lead-ining line connects with the positive pole of D5 and the negative pole of D4 respectively, and load is attempted by on the positive pole of D5 and D1.Its operation principle is: after the energising because the charging of C1 makes the conducting of SCR1 rise to maximum gradually by null value, this moment load voltage equally also by null value to peak, be soft starting circuit, avoided the load incandescent lamp to be subjected to the impact of surge current.In addition, when electric voltage over press, cause that the pressure drop of W1 two ends increases, provide BG1 base signal voltage to increase, the BG1 internal resistance is descended, shunted the trigger current of SCR1, cause the SCR1 angle of flow to diminish, respective load voltage descends or remains unchanged.
The utility model compared with prior art not only can be avoided the impact of surge current to incandescent lamp, and has low, the overvoltage adjustment of power consumption, prolongs the incandescent lamp advantage in useful life.
