Abstract

The utility model relates to a safety power-saving xenon head lamp of a vehicle, which comprises a head lamp, wherein both ends of the head light are matched and provided with ballasts. The voltage output tail ends of the ballasts are connected with a pre-warning circuit in parallel. The pre-warning circuit comprises a tube pressure sample circuit and an indicating circuit which can are connected in series, wherein the indicating circuit is formed by connecting a plurality of groups of cue circuits with different working voltages in parallel, and each of the cue circuits comprises an amplifying part and an indicating component driven by the amplifying part; the voltage input end of the tube pressure sample circuit is connected with the voltage output tail ends of the ballasts in parallel. The utility model can reflect the service life of the head light through testing the tube pressure. The more number of indicating lamps which are lightened, the longer service life of the head lamp, and contrarily, the service life of the head lamp is shorter. Especially when only one indicating lamp is lightened, a driver is reminded to replace the head lamp in time. The utility model can indicate the operating status of a head lamp of a vehicle at any time so as to protect the illuminating quality and ensure that a driver can safely drive a vehicle. The utility model has the advantages of little energy consumption and simple structure.

Description

A kind of vehicle xenon headlamp that economizes on electricity safe

Technical field:

The utility model relates to the car headlamp technical field, refers in particular to a kind of vehicle xenon headlamp that the economize on electricity safety of safe early warning is provided.

Background technology:

Car headlamp is as the important component part in the automobile, plays crucial effects for car steering person's safety.The principle of luminosity of xenon lamp is to utilize positive and negative electrostimulation xenon and rare metal chemical reaction luminous, under the stable drive of ballast, work, on average can economize on electricity more than 50%, thereby it is strong to have brightness, power saving, life-span is long, safe, advantage such as should be acute good, thereby replaced Halogen lamp LED and be widely used as car headlamp, but, no matter xenon lamp, Halogen lamp LED, the time of origin of traffic accident, be that chief reason is that the sight line of driving under these situations is relatively poor usually under night and weather bad situations such as (as the greasy weathers) more than 60%, the driver must watch the road surface with breathless interest, cause fatigue and dispersion attention indirectly, thereby traffic accident takes place.Simultaneously, owing to computer, intelligent air condition, GPS, liquid crystal DVD system sound equipment, mobile phone etc., all become the basic configuration of car successively, these equipments all need power consumption, and this has just increased a large amount of loads to automobile storage battery.Through experiment as can be known; the pipe of xenon lamp is pressed high more; its useful life is short more, otherwise pipe is pressed low more; useful life is long more; suddenly to extinguish be breakneck to car light in vehicle ', and if do not have emergent bulb on hand, long distance driving under the situation of no headlamp; lack active safety protection and passive security protection, driving is a danger close.

Summary of the invention:

The purpose of this utility model is thereby that a kind of a kind of vehicle xenon headlamp that economizes on electricity safe that can indicate the car headlamp operating state to guarantee lighting quality at any time and then guarantee traffic safety is provided at the deficiencies in the prior art.

For achieving the above object, the utility model adopts following technical scheme: it includes headlamp, the headlamp two ends are combined with ballast, and ballast voltage output end is parallel with early warning circuit, and this early warning circuit comprises pipe pressure sample circuit and the indicating circuit that is cascaded; Indicating circuit is formed in parallel by the many groups of cue circuits with different operating voltage; Cue circuit comprises amplifier section and the indicating device that is driven by amplifier section; Pipe presses the voltage input end of sample circuit terminal in parallel with the voltage output of ballast.

Described pipe presses the voltage input end of sample circuit to be in series with protective resistance respectively.

Described indicating device is a light-emitting diode.

Wherein, pipe presses sample circuit to be connected to the headlamp of automobile, at any time indicate the operating voltage of headlamp, and different voltage is with the different indicator light of lighting respectively in the cue circuit of operating voltage, the bright quantity of indicator light multilist exposed conduit more presses low more, the few more pipe that shows of quantity to press big more, particularly when having only an indicator light bright, remind the driver in time to change headlamp.

Thereby the utility model can be indicated car headlamp operating state protection lighting quality at any time and then be guaranteed traffic safety, has low, simple in structure, the practical advantage of energy consumption, is fit to apply.

Description of drawings:

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

Fig. 1 is the schematic diagram that pipe of the present utility model is pressed sample circuit;

Fig. 2 is the schematic diagram of indicating circuit of the present utility model.

Embodiment:

See accompanying drawing 1,2, the utility model includes headlamp 11, headlamp 11 two ends are combined with ballast, the voltage output end of ballast is parallel with early warning circuit, this early warning circuit comprises pipe pressure sample circuit 1 and the indicating circuit that is cascaded, wherein pipe pressure sample circuit 1 is connected to the headlamp 11 of automobile, and terminal in parallel with the voltage output of ballast, and pipe presses output terminals A, the B of sample circuit 1 to connect with A ', the B ' of indicating circuit.Ballast provides operating voltage for early warning circuit, and the utility model ballast remainder all adopts existing ballasting circuit, so do not give unnecessary details at this.

Pipe presses the voltage input end of sample circuit 1 to be in series with protective resistance R respectively, when opening headlamp 11, because the starting resistor of xenon lamp is very high, so the resistance of protective resistance R is generally bigger; It is general voltage detecting circuit that pipe of the present utility model is pressed sample circuit 1, so do not give unnecessary details one by one at this.

Indicating circuit is formed in parallel by the many groups of cue circuits 2 with different operating voltage.

Cue circuit 2 comprises amplifier section 21 and indicating device, amplifier section 21 with after the voltage amplification for indicator light provides starting resistor, indicating device can be installed in the driver's cabin by lead, makes things convenient for the driver to check.Indicating device of the present utility model adopts the light-emitting diode device of giving instruction, and also can adopt other elements certainly, and existing is that example is explained its operation principle with three groups of cue circuits 2.Wherein, the resistive element in the scalable indicating circuit 2, make when voltage between A ' B ' lower, also be that headlamp 11 pipes are pressed when hanging down, L1, L2, L3 are bright entirely, and when voltage between A ' B ' raise, L1, L2 were bright, L3 extinguishes, when voltage is elevated to higher value between A ' B ', also be that headlamp 11 is managed when pressing greatly, a L1 is bright, and this moment is as if not changing headlamp 11, then its pipe is pressed and will be continued rising and arrive and scrap, and L1, L2, L3 do not work entirely.

In fact, the utility model is the useful life of reacting headlamp 11 by cue circuit 2, bright 11 life-spans of headlamp of multilist are long more more, quantity is few more shows that 11 life-spans of headlamp are short more for the bright quantity of indicator light, particularly when having only an indicator light bright, remind the driver in time to change headlamp 11.

The utlity model has early warning effect preferably, effectively prevent to cause various pernicious traffic accidents because of bulb extinguishes suddenly.
