Brief description of the drawings
Fig. 1 is the circuit diagram of the utility model.
Embodiment
The utility model is described further below in conjunction with the accompanying drawings：
As shown in Figure 1, the flashers for being applicable in light bulb different steering lamp loads with LED of the present embodiment, including relay K1,
Triode T1, T2 and diode D1, D2, the emitter of triode T1 are connected through switching K2 with the cathode of power supply, triode T1's
Collector is connected through resistance R2 with the base stage of triode T2, and the base stage of triode T1 is successively through discharge circuit, switch K3 and load
It is connected, the anode of diode D1 is connected with the collector of triode T2, its cathode is connected with the emitter of triode T1, relay
The both ends of K1 coils are parallel to the both ends of diode D1, and the stationary contact of relay K1 is through two resistance R5, R6 in parallel and switch K3
End of incoming cables be connected, the emitter of triode T2 is connected with the anode of diode D2, cathode and the power cathode phase of diode D2
Even, the base stage of triode T2 is connected through resistance R3 with the emitter of triode T2.
The discharge circuit of the present embodiment includes resistance R1, R4 and capacitance C1, C2, one end of resistance R4 and the base of triode T1
Extremely it is connected, its other end is connected through capacitance C2 with the anode of diode D1, one end of capacitance C1 and the collector phase of triode T1
Even, its other end is connected through resistance R1 with switch K3, and the base stage of triode T1 is connected between capacitance C1 and resistance R1.
Operation principle：Power switch K2 is connected, but during turning indicator control K3 access failures, at this moment flasher does not export,
Non-loaded, flasher output is drawn high to supply voltage by R5, resistance R1 no currents by, triode T1, T2 are not turned on, glisten after
Electric appliance K1 does not work；When switch K2, K3 are connected, at this moment flasher power supply is powered, and flasher output is switched through to lamp load, is at this moment dodged
Light device output be supported resistance R7 and R8 connect it is low, resistance R1 detection load, produce Weak current, electric current at this moment is triode
The BE junction currents of T1, zoom into larger current by the β value of triode T1 and pass through current-limiting resistance R2, divider resistance R3, is added to
The BE of triode T2 is tied, then is amplified to more high current by the β value of triode T2, and flashing relay K1 is attracted, and flasher is defeated
Go out the contact portion by flashing relay K1 to power supply, steering indicating light is bright；
Meanwhile the collector extremely low level of flashing relay driving triode T2, and the base stage of flasher triode T1
Close to supply voltage so that discharge and recharge resistance R4, charge and discharge capacitance C2 both ends produce pressure drop, form RC charging circuits, and at this moment three
The BE junction currents of pole pipe T1 are further amplified to the BE junction currents of triode T2, and flasher, which is attracted, can continue to carry out, steering indicating light
Persistently light, and produce the timing effect of flasher actuation.When charging current is reduced close to 0 in RC charging circuits, three poles
The BE junction currents of pipe T1 also begin to reduce, and at this moment the BE junction currents of triode T2 also begin to reduce, the C pole tension liters of triode T2
Height, at this moment relay K1 disconnections, steering indicating light extinguish.
At this time, the charging of capacitance C2, there are voltage close to supply voltage, the collector voltage liter of triode T2 at its both ends
Height, RC circuit voltages it is reverse-biased, the base voltage of triode T1 is higher than emitter voltage, triode T1, T2 cut-off, relay K1
It is not attracted, capacitance C2 is steering indicating light power supply to flasher load by resistance R4, resistance R1, and steering indicating light is bright, forms flasher
Release is lasting to be carried out, and produces the timing effect of flasher release.When the charge discharge of capacitance C2 storages is close to 0, flash of light
Device is returned to above-mentioned load detecting process, so circulation, forms flash effect.
