Embodiment
Describe specific embodiment of the utility model in detail below in conjunction with accompanying drawing.
The utility model provides a kind of equipment that promotes the automobile head light performance, whether this equipment can detect the power of headlight of new clothes automatically consistent with the power of former headlight, and can overcome before the repacking and repacking back because of the unmatched technical problem of light source power, can also reduce the electromagnetic interference that ballast produces.
As shown in fig. 1, Fig. 1 is the equipment of the related lifting automobile head light performance of the utility model, and this equipment selects circuit 3, second filtration module 4, detection module 5 and power match module 6 to form by anti-reverse module 1, first filtration module 2, switch.Wherein the positive pole of this anti-reverse module 1 is connected with automobile power source, can prevent effectively that installation personnel from connecing both positive and negative polarity instead, thereby causes entire circuit to be damaged.Under the purpose that realizes technique effect of the present utility model, this anti-reverse module 1 also can be omitted.What be connected with anti-reverse module 1 is first filtration module 2, and this first filtration module 2 selects circuit 3 to be connected with ballast and switch simultaneously.The noise that the use of first filtration module 2 had been produced in the time of both can having reduced ballast work is to the interference of automobile circuit system, the interference that in the time of can also reducing the automobile circuit system works simultaneously ballast is produced.It can be toggle switch, push-button switch, remote control switching circuit or other any type of switching circuits that switch is selected module 3.By selecting different switches, make its conducting, can select to use the different functional module of selecting module 3 to be connected with switch.
In the utility model this switch select module 3 to three functional modules being arranged, second filtration module 4, detection module 5 and power match module 6.When one of them switch closure of this switch selection module 3, circuit is connected, and the pairing functional module of this switch can be had an effect.Such as, certain automobile its original-pack be the halogen headlamp, after repacking, headlamp is replaced by gaseous discharge lamp or LED lamp.In the prior art, detect the new clothes headlight by automotive control system usually and former headlight power (setting power when promptly dispatching from the factory) is inconsistent, the sound that will give the alarm, even the new headlight after the repacking also can't normally use.Technical scheme provided by the utility model can be utilized these detection module 5 active detecting and judge whether the power of headlight of new clothes is consistent with the power of former headlight, avoids by the passive detection of automotive control system.When detection module 5 detect power inconsistent after, can select module 3 to switch to and 6 conductings of power match module on switch in manual or automatic mode, and solve the inconsistent problem of power of headlight before and after the repacking by this power module 6.The use of second filtration module 4 is in order further to eliminate the electromagnetic interference that ballast is in use produced.
Can be designed to a mancarried device to the equipment of this related lifting automobile head light performance of the utility model in engineering practice, this mancarried device is by metal shell, and switch, circuit and connecting line are formed.The composition of circuit is described in the foregoing.For solving the heat dissipation problem of circuit, preferably, this metal shell uses aluminum alloy casing usually.Technical scheme provided by the utility model is applicable to the headlight between the 5W to 75W.The equipment of this lifting automobile head light performance is connected with ballast with automobile power source respectively in use, and connecting line is general to divide two groups and can stamp binding post and install with convenient, a winding automobile power source wherein, and another group connects the ballast of new type light source.The circuit that below will specifically describe each module of circuit part constitutes.
As shown in Figure 2, Fig. 2 is the circuit structure diagram of the related anti-reverse module of the utility model.Being made up of a NMOS (N-Mental-Oxide-Semiconductor) pipe Q2 and resistance R 7 of this anti-reverse module, the G utmost point of resistance and this NMOS pipe Q2 connects to form a reverse-connection preventing circuit, prevents to be burnt out ballast on the contrary because of both positive and negative polarity connects.Because metal-oxide-semiconductor is a voltage controlled element, if power positive cathode meets anti-V
GSCan not form forward bias, then the metal-oxide-semiconductor D utmost point, the S utmost point just can not conductings, and power supply can not form the loop, thereby reaches the protection effect.
As shown in Figure 3, Fig. 3 is the circuit structure diagram of the first related filtration module of the utility model.First filtration module comprises a common mode choking-winding L2 and electrochemical capacitor C8, C9 and ceramic disc capacitor C10, the C11 in parallel with this common mode choke coil L2.Common mode inductance is on the same magnet ring two independently coils, and their numbers of turn are identical, and iron core is generally selected ferrite for use, when electric current enters coil, the magnetic flux that two coils produce in magnet ring is strengthened mutually, and common-mode noise is presented very high impedance, thereby suppresses common-mode noise.C8, C10 and C9, C11 form simple filter circuit respectively can filtering ballast (or claiming stabilizer, stabilizer) power supply is imported or self produces part High-frequency Interference and low-frequency disturbance.
Fig. 4 is the circuit structure diagram of the second related filtration module of the utility model.The use of second filtration module is in order further to eliminate the electromagnetic interference that ballast is in use produced, therefore can to select for use according to actual requirement of engineering.As shown in Figure 4, this second filtration module is formed in parallel by electrochemical capacitor C12, C13, C14 and ceramic disc capacitor C15.Because the function that ballast has voltage stabilizing and regulates power, certainly exist transformer and switch element, their operating frequency generally also in 200KHz, can produce a large amount of low frequency noises signals thus, therefore needs a plurality of electrochemical capacitors and ceramic disc capacitor parallel connection to come this noise signal of filtering.
Fig. 5 is the circuit structure diagram of the related detection module of the utility model, and in this detection module, resistance R 8 is power resistors, and an end connects power supply, and the other end is connected with relay J 3.The part vehicle has the power functions of last electro-detection lamp, this circuit can moment and the transducer that detects of car running computer form loop, electric current by resistance again through the common end grounding of relay, car running computer detects and finishes, relay powers on immediately and disconnects and being connected of resistance R 8, and finishes a duty cycle.Relay another one important function is exactly to play the effect of time-delay.
Fig. 6 is the circuit structure diagram of the related power match module of the utility model.Can solve the preceding and unmatched problem of repacking back headlight power of repacking by at least one power resistor in parallel.
Described in this specification is preferred embodiment of the present utility model, and above embodiment is only in order to the explanation the technical solution of the utility model but not to restriction of the present utility model.All those skilled in the art comply with design of the present utility model by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should be within scope of the present utility model.
