Abstract
The utility model discloses a novel flickering prevention device for an electronic energy-saving lamp, which is characterized in that a discharging circuit consisting of a resistor R7 and an electrolytic capacitor C is parallelly connected between one end of a bilateral diode in an inverter circuit and the electrolytic capacitor C. The novel flickering prevention device solves the problem that in the prior electronic energy-saving lamp, in the case that a power indicator is arranged on a control switch or the control switch is misconnected with a control zero line, a shunt allowing tiny electric current to pass through is formed to cause that the electronic energy-saving lamp flickers every several minutes.
Description
One, technical field:
The utility model relates to a kind of anti-flicker apparatus that is used for electronic energy-saving lamp, belongs to technical field of lamps.
Two, background technology:
Present electronic energy-saving lamp basic circuit, electronic energy-saving lamp has power supply indicator or control switch misconnection to become the control zero line on control switch, formation can be by the path of Weak current, because discharge off loop, diac is easy to mislead, and makes a few minutes electronic energy-saving lamps just dodge 1 time phenomenon.Be head it off, the resistance of the power circuit output end that connects filter capacitor at power input, has that has 1 high value in parallel, cost height; Simultaneously, owing to can form little current circuit, so waste energy.
Three, summary of the invention:
The utility model is the deficiency that overcomes above-mentioned prior art, a kind of novel electron electricity-saving lamp anti-flicker apparatus is provided, mainly having solved electronic energy-saving lamp has power supply indicator or control switch misconnection to become the control zero line on control switch, formation can be passed through the pettiness current paths, causes a few minutes electronic energy-saving lamps just to dodge 1 time phenomenon; The cost height of making during with head it off, the phenomenon that wastes energy.
In order to achieve the above object, the utility model adopts following technical scheme: the utility model is made of shell and electronic circuit, be in the inverter circuit (2) in the electronic circuit, the end of a termination diac D after R7, the C5 parallel connection, the other end links to each other with the negative pole of electrochemical capacitor C.
Compared with the prior art the utility model has following good effect: 1, power consumption is little; 2, cost is low; 3, effectively solve lamp flicker problem.
Four, description of drawings:
Fig. 1 is the utility model electronic circuit electrical schematic diagram.
In the drawings, 1-power circuit, 2-inverter circuit, 3-load circuit.
Five, embodiment:
Embodiment: with reference to Fig. 1, the utility model preferred forms is: in power circuit (1), connect the respectively input of the bridge rectifier that fuse F, inductance L 1 back and D1-D4 form of power input T1,12 links to each other electrochemical capacitor C in parallel between its output; In inverter circuit (2), R2, R1, C4 and K1 collector electrode connect the anodal of power circuit (1) respectively and link to each other with filament T6 by C2, R2 by the D7 that just connecing respectively with R1, C4, R5, D5 positive pole and B1, the common port of B3 links to each other, the K1 emitter links to each other with the other end of R5, the K1 base stage is by R3 and B other end limit and connect the D5 negative pole mutually, R7, an end meets an end and the R2 of D respectively after the C5 parallel connection, the common port of D7, the other end of D links to each other with the K2 base stage, K2 collector electrode and D7 negative pole, R1, C4, R5, D5 positive pole and B1, the common port of B3 links to each other, the K2 emitter is by R6 and R7, C5, the D9 positive pole, the common port of B2 links to each other, the K2 base stage also links to each other with the D9 negative pole, the other end of B3 connects the end of L2, the other end of L2 links to each other with filament T3, in the load circuit (3), and filament T5, shunt capacitance C3 between T4.
In the present embodiment, D1-D4, D5, D7, D9 are that 1N4007 type diode, T1, T2 are 13003 type NPN triodes, and D is a DB3 type diac.
