Abstract

The utility model relates to a multifunctional flash apparatus, which comprises a current-limiting voltage-stabilizing circuit, a single-flash LED, a triode and a relay, wherein the current-limiting voltage-stabilizing circuit is composed of a R1, a C1 and a WD1. A power supply supplies working power to the single-flash LED via the current-limiting voltage-stabilizing circuit, and as the single-flash LED is a light-emitting diode with a logic chip, current which flows through the (+) and (-) ends of the light-emitting diode in operation can make-and-break along with flash and extinguishing of the single-flash LED. Thereby, the triode BG1 connected to the single-flash LED via R2 can be intermittently conducted along with the single-flash LED to control a contact of the relay to be intermittently on-and-off, and further enables the light controlled by the contact to flash. The utility model can control lights with various power to flash in various occasions, as a new electronic element single-flash LED is utilized as a flash control, the flash apparatus is simple in structure, reliable in operation, low in manufacturing cost and economical in resources.

Description

Adopt single LED of sudden strain of a muscle to make the multipurpose flasher of control

One, technical field

The utility model relates to a kind of manufacturing process of Traffic alarm light, and especially a kind of steering lamp for motor vehicle flasher and brake lamp flash controller are fit to the dangerous applications of various types of vehicles and needs caution.

Two, technical background

The caution blinking light is very extensive at motor vehicle and road junction, construction site and deathtrap application, and particularly the steering lamp for motor vehicle flasher can be realized though have multiple mode at present, as hot relay, electronic type, electric capacity relay etc.But exist flashing rate shakiness, bearing power quota, function singleness or manufacturing cost higher mostly.And brake caution aspect still adopts when stepping on brake at present, and the mode that brake lamp is lighted is warned the back car, is not enough to produce strong caution to the back car.

Three, summary of the invention

The purpose of this utility model provides a kind of multipurpose flasher that improves the flicker control mode, has adopted new electronic component to remedy the deficiencies in the prior art, can control the different light flash of various power reliably in multiple use occasion.And can reduce manufacturing cost, save resource.

The utility model comprises: current limliting mu balanced circuit, single LED of sudden strain of a muscle, triode and relay are formed basic circuit.Described current limliting mu balanced circuit is connected in power supply, stable working power is provided for single LED of sudden strain of a muscle (+) end, single (-) end that dodges LED is connected in the base stage of triode, coil one end of described relay connects the colelctor electrode of triode, the other end connects power supply, and the normally-closed contact of relay is made output and connected load.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Five, the specific embodiment

As shown in Figure 1, the current limliting mu balanced circuit is made up of resistance R 1, voltage-stabiliser tube WD1 and capacitor C 1, for single LED of sudden strain of a muscle powers, makes the single LED of sudden strain of a muscle work, because single to dodge LED is the light emitting diode that carries logic chip, the electric current that flows through its (+), (-) two ends during work can dodge, go out and switching with it; Therefore, the triode BG1 that base stage is connected in single LED of sudden strain of a muscle (-) end by resistance R 2 is also with its intermittently conducting, and the relay J that makes coil pass through BG1 ground connection intermittently opens and closes, the common port of relay connects power supply, normally-closed contact connects load, makes light realize flicker continuously, produces the caution effect.

Fig. 2 shows the circuit theory diagrams of the utility model as brake lamp flash controller embodiment, increases a delay circuit in above-described basic circuit, and it comprises that resistance R 3, capacitor C 2, voltage-stabiliser tube WD2 and triode BG2 form.Concrete principle is: after brake switch is connected, circuit gets electric work, brake lamp gets started flicker, and power supply also charges to capacitor C 2 through resistance R 3 simultaneously, when the C2 charging voltage is higher than the voltage stabilizing value of voltage-stabiliser tube WD2, the conducting of WD2 reverse breakdown, the base stage that voltage is added in triode BG2 makes its conducting, and the base stage shorted to earth with BG1 ends BG1, relay J resets thereupon, at this moment brake lamp Chang Liang.Owing to can when brake, send continuous flashing signal, effectively improved warning function, thereby reduced the generation of rear-end collision the back car.

Fig. 3 is the embodiment circuit theory diagrams of the utility model as the steering indicating light flasher, owing to need to cooperate former car contactor design, must add an electronic switching circuit at power end, achieve after load is connected, entire circuit just electric work, it is made up of photoelectronic coupler IC and resistance R 4.Concrete principle is: after turning indicator control was connected load, power supply was through 1,2 pin of resistance R 4 by IC, again through turning indicator control, bulb ground connection because 1,2 pin of IC have electric current to pass through, 3, make 4 pin thereupon conducting power supply supplied with entire circuit make its work.The normally opened contact of this programme repeat circuit J is connected with 2 pin of IC and is connected in turning indicator control as output, behind the common port and normally opened contact connection of J, steering indicating light is bright, this moment because of 2 pin of IC simultaneously 3,4 pin of the electric IC of causing end, power supply temporarily disconnects, but because the electric power storage effect of capacitor C 1 can allow circuit be maintained the normally opened contact disconnection of work to J, circuit restores electricity, go round and begin again, realize driving the continuous flicker of steering indicating light, end until disconnecting turning indicator control.Because adopted photoelectronic coupler to make the control of load switch monitoring, therefore, the adaptability of bearing power is very high, can be suitable for the minimum LED lamp of electric current, more can drive common automobile-used bulb.Because of its flicker frequency with bearing power irrelevant, control that can also the two flashing lights of the emergent warning of double as.Realize a device multipotency, saved resource.
