Abstract
The utility model discloses a kind of drive circuit of double light LED cars headlight fans, the positive pole of fan is conllinear with the positive pole of the double lamps of LED, the negative pole of fan is connected in two negative lines of the double lamps of LED respectively, and an anti-reverse diode is equipped between two negative lines of the double lamps of negative pole and LED of fan.The utility model is when each group of LED of automobile control automobile is luminous, fan can all work, such creativity and innovation, only car headlight lamp body can be entered with three electric wires, reduce cost, the lamp assembled time is saved, user is facilitated when car light is installed, the success rate of the Vehicle clamp mounting greatly improved.
Description
Technical field
A kind of drive circuit is the utility model is related to, specifically a kind of drive circuit of double light LED cars headlight fans.
Background technology
Double light LED car headlights fans are supplied using single both positive and negative polarity is made from drive circuit to fixed DC fans at present
Electricity, as long as driving switches on power, fan just works, and for this circuit in the realization of electrical connection, double groups of luminous LED's is positive and negative
Fan both positive and negative polarity is added in pole, needs the electronic connecting lines of 6 difference polarity altogether, because LED car headlights are that to be placed in automobile big
High to volume requirement inside lamp assembly, volume crosses conference and causes installation inconvenience not install even.
The content of the invention
The purpose of this utility model is to provide a kind of drive circuit of double light LED cars headlight fans, to solve the above-mentioned back of the body
The problem of being proposed in scape technology.
To achieve the above object, the utility model provides following technical scheme：
A kind of drive circuit of double light LED cars headlight fans, the positive pole of fan is conllinear with the positive pole of the double lamps of LED, fan
Negative pole is connected in two negative lines of the double lamps of LED respectively, and one is equipped between two negative lines of the double lamps of negative pole and LED of fan
Anti-reverse diode.
As further program of the utility model：The anti-reverse diode is distributed on one piece of switching pcb board.
As the utility model further scheme：The anti-reverse diode, which is distributed in single negative line, does shell
Protection.
Compared with prior art, the beneficial effects of the utility model are：The utility model is each automobile control automobile
When group LED is luminous, fan can all work, such creativity and innovation, only can enter car headlight lamp body with three electric wires, reduce
Cost, saves the lamp assembled time, user is facilitated when car light is installed, the success of the Vehicle clamp mounting greatly improved
Rate.
Brief description of the drawings
Fig. 1 is the circuit diagram of the drive circuit of double light LED car headlight fans.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole implementation
Example.Based on the embodiment in the utility model, those of ordinary skill in the art are obtained under the premise of creative work is not made
The every other embodiment obtained, belong to the scope of the utility model protection.
Referring to Fig. 1, in the utility model embodiment, a kind of drive circuit of double light LED cars headlight fans, fan is just
Pole is conllinear with the positive pole of the double lamps of LED, and the negative pole of fan is connected in two negative lines of the double lamps of LED respectively, the negative pole and LED of fan
An anti-reverse diode is equipped between two negative lines of double lamps.
The anti-reverse diode is distributed on one piece of switching pcb board.
The anti-reverse diode, which is distributed in single negative line, does shell protection.
Referring to Fig. 1, LED 1, the lamp string of LED2, LED3 composition are lamp A, LED 4,
The lamp string of LED5, LED6 composition distinguishes connecting luminous diode LED4 positive poles, fan F1 positive poles and power supply V for lamp B, LED1 positive pole
+, LED1 negative poles connection LED2 positive poles, LED2 negative poles connection LED3 positive poles, LED3 negative poles connect respectively returns anti-diode D1 negative poles
With power supply H-, diode D1 positive poles connect fan F1 negative poles and counnter attack diode D2 positive poles respectively, and LED4 negative poles connection LED5 is just
Pole, LED5 negative poles connection LED6 positive poles, LED6 negative poles connect respectively returns anti-diode D2 negative poles and power supply L-.So in automobile control
When each group of lamp string of automobile processed is luminous, fan F1 can work.
The special focus on the application of this example implementation case is in the H4 of car headlight, H13, HB2 (9004), HB5 (9007), double-colored intelligence
Headlight, in double-colored intelligent fog lamp.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and
And in the case of without departing substantially from spirit or essential attributes of the present utility model, it can realize that this practicality is new in other specific forms
Type.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and is nonrestrictive, this practicality is new
The scope of type limits by appended claims rather than described above, it is intended that the equivalency fallen in claim is contained
All changes in justice and scope are included in the utility model.Any reference in claim should not be considered as limitation
Involved claim.
Moreover, it will be appreciated that although the present specification is described in terms of embodiments, not each embodiment is only wrapped
Containing an independent technical scheme, this narrating mode of specification is only that those skilled in the art should for clarity
Using specification as an entirety, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
It is appreciated that other embodiment.
