The utility model has the characteristics of quick response, obvious signal, and long service life.

Description

Self-propelled vehicle high speed brake taillight

The utility model relates to the used brake taillight of a kind of power actuated vehicle that is used for, particularly automobile.

Along with development and national economy, power actuated vehicle increases substantially, and traffic density is very big on the road.Because accident is inevitable, like this, when high speed traveling, has very important accident potential especially.Rear crash event happens occasionally.Common brake taillight adopts filament bulb to add red lamp shade, and after the not only eye-catching inadequately shortcoming of existence, and driver was stepped on brake pedal, the filament lamp needs delay time could be normally luminous.This has lost the valuable reaction time with regard to the driver who makes the back.The ornamental luminotron that connects together with stoplight stop lamp is installed by some luxury car on rear window, though shortened delay time greatly, itself cost is higher, inconvenience is installed and is difficult to popularize.

The purpose of this utility model provides a kind of eye-catching, quick and and used compatible fully high-performance motor vehicle brake taillight of filament bulb of ordinary motor vehicle stoplight stop lamp.

The purpose of this utility model is achieved in that

The same circuits unit that adopts N (getting N=6 among the embodiment) to be connected in parallel, two public input end P, G are as the two poles of the earth of bulb.P termination+12V power supply wherein, G holds ground connection.Each circuit unit all adopts current stabilization circuit to 4-6 red high brightness luminescent pipe power supply that is cascaded, current stabilization circuit input termination P end, mouth sending and receiving light pipe anode.The luminotron negative terminal meets G.

Current stabilization circuit adopts two NPN type aerotron V1, V2, the e utmost point sending and receiving light pipe anode of V1, and the b utmost point connects the e utmost point of V2, and the c utmost point connects the b utmost point of V2, and the b utmost point, e interpolar meet a sample resistance R2; The b utmost point of V2 connects the P end by a biasing resistor R1, and the c utmost point connects the P end.

Stabilivolt of the equal reverse parallel connection in each luminotron two ends.Thereby arbitrary luminotron open circuit, corresponding stabilivolt conducting makes other luminotron normal operation; Obviously owing to the effect of current stabilization circuit, arbitrary luminotron short circuit does not influence other luminotron work yet.

Foregoing circuit is packaged into the shape (luminotron is outside) that the self-propelled vehicle ordinary incandescent lamp steeps, promptly becomes the utility model.

As shown from the above technical solution, the common stoplight stop lamp incandescent light bulb of the utility model direct substitution, easy to use; As luminary, respond fast and eye-catching with luminotron; The semiconductor devices life-span is very long, and the utility model is designed to N independent circuits unit, and each unit luminotron all can work independently again, and the possibility of Sun Huaiing is minimum simultaneously, thereby has very high reliability.

The utility model is described in further detail below in conjunction with drawings and Examples.

Accompanying drawing 1 is schematic circuit diagram of the present utility model.

Accompanying drawing 2,3 is a pcb map of the present utility model.

See circuit unit shown in dotted lines in Figure 1 ,+12V voltage is by biasing resistor R1 conducting V2, and powers to luminotron by sample resistance R2.V1 conducting degree is regulated in the R2 pressure drop, thereby the b pole tension of regulating V2 makes current stabilization.Since not high to the working current stability requirement of luminotron, so the current stabilization circuit design-calculated is simple as far as possible.

Among Fig. 2+,-number indicate each luminotron positive and negative electrode, the equal arrangement in parallel of all luminotrons.Stabilivolt directly is welded in corresponding luminotron position, the wiring board back side, and is clear understandable for figure, do not draw among the figure.Respective point in A among Fig. 2, B, C, D, E, F, the corresponding connection diagram 3 of G.

Fig. 3 is the current stabilization circuit part.During use Fig. 3 printed board overlayed printed board back shown in Figure 2, and P, G as encapsulation exit (P power connection+, G ground connection).In fact circuit shown in Figure 3 can be integrated into a slice thick film circuit, directly is welded in the printed board shown in Figure 2, will not describe in detail herein.

Owing to have rotational symmetry, Fig. 2, Fig. 3 only to indicate the element of a circuit unit.

Experimental result:

Truly have good effect through examination the utility model, accelerated aging test shows reliable operation.Principal parameter: R2=7 Ω, R1=1k, V1, V2 β＞150.Encapsulation is ripe prior art, no longer discusses at this.
