Technical background:

All kinds of indicator lamps that are used in the car field at present mostly adopt traditional incandescent lamp to show, big, the colored display mode of its power consumption bothers, planar display effect is poor, the waterproof moisture resistance wet and shock resistance difference and life-span weak point.When particularly being used in the brake of motor-driven vehicle demonstration, effect is obvious inadequately, poor stability.

Summary of the invention:

Goal of the invention of the present utility model provides the vehicle lamp that a kind of rational in infrastructure, circuit is simple, save the energy, long service life, raising security and the multiple flicker Presentation Function of tool.

Realize that technical solution of the present utility model is as follows: comprise base and Transparent lamp shade, key is the wiring board that base is provided with a tool control circuit, and wiring board is provided with a plurality of light emitting diodes, and the pin of LED light emitting diode and the control circuit of wiring board join.

The utility model adopts the LED light emitting diode as light source, with replace incandescent, have power saving, good optical properties, long service life and safe and reliable demonstration, brightness height, indication is obvious, low in energy consumption, the life-span long, be suitable for multiple power supply uses, and the multiple flicker display mode of tool, improved automobile-used indicator lamp display efficiency, and can adopt LED luminous tube of all kinds, and multiple layout is combined to form various difformities and shows, and antidetonation, water resistance are good.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a circuit diagram of the present utility model.

The specific embodiment:

See also Fig. 1～Fig. 2, specific embodiment of the utility model is as follows: comprise base 2 and Transparent lamp shade 1, key is the wiring board 4 that base 2 is provided with a tool control circuit, and wiring board 4 is provided with a plurality of light emitting diodes 3, and the control circuit of the pin of LED light emitting diode 3 and wiring board 4 joins; Be laid with the control circuit wiring on the wiring board 4, lead 6 one ends are connected with the circuit of wiring board 4, and its other end has a plug 7, and plug 7 joins with the control circuit of vehicle, the control circuit wiring welding of the pin of LED light emitting diode 3 and wiring board 4; Control circuit on the wiring board 4 is made up of oscillating circuit, signal distribution circuit and amplification driving circuit, wherein oscillating circuit is that IC 1, resistance R 1, R2 and capacitor C 1 constitute, IC1 can select CD4062 decimal radix distributor for use, R1 and R2 are oscillation resistances, C2 is an oscillating capacitance, R1, R2 are connected with IC1 with C2, and the output of IC1 and signal distribution circuit input join; Signal distribution circuit is an IC 2, and IC2 can select CD4017 decimal radix distributor for use, and each output of IC2 and one group of amplification driving circuit join; Every group of amplification driving circuit is made of a resistance and a triode, and the base stage of triode and IC2 output join, and its colelctor electrode and LED light emitting diode join; IC1 is provided with a K switch; R3～R7 drives transistor base resistance, and T1～T5 drives triode, and R8～R12 is a LED light emitting diode current-limiting resistance, and D1 is a steering indicating light power supply diode, and D2 is a brake lamp power supply diode, and K is the normal bright selection function switch of brake lamp; As shown in Figure 2, IC1, R1, R2, C1 forms the oscillator signal circuit, the concussion frequency is that 10 hertz signals are exported to the IC2 input by output, with signal in order respectively 1,2,3,4,5 outputs output high potential is given LED group light emitting diode amplification driving circuit, by R3 to R7 is that T1 to T5 transistor base resistance is respectively with triode conducting work, this moment, transistor collector was an electronegative potential, be connected on LED group light emitting diode negative pole by R8 to R12 current-limiting resistance respectively again, LED group light emitting diode positive pole is connected on the power supply on vehicle anode, and LED group light emitting diode is the luminous duty of conducting at this moment; D1 is a steering indicating light power supply diode, and when positive source inserted the D1 positive pole, it is luminous with all group luminous tube conductings of LED that electric current flows through D1, and when the diode cathode no-voltage, all group luminous tubes stop luminous, turn to flicker effect thereby reach; D2 is a brake lamp power supply diode, when positive source inserts the D2 positive pole, electric current flows through D2 supplies with dynamic control circuit work, making indicator lamp is dynamic show state, become circular round as LED being organized luminous tube, the light efficiency that then sends is outwards to be scattered with the speed of twice circulation of per second by center circle, and this has just realized dynamic very strong indicating effect, its use effect on the brake of motor-driven vehicle lamp is very good, and dynamic illumination effect is very obvious; K is the normal bright switch of brake lamp, the positive power signal of will braking when it closes is directly sent into IC2 signal cycle distributor input, make its output all export high potential and give LED group light emitting diode amplification driving circuit, thereby make all LED group lumination of light emitting diode reach the Chang Mingxiao fruit, when the fog lamp signal was input to the T3 base stage, the T3 conducting should organize that the luminous tube conducting is luminous to be used as fog lamp.
