The utility model content
The technical problems to be solved in the utility model is, a kind of automotive lighting circuit is provided, if when the head lamp circuit breaks down, country beam L2, the L4 or passing light L1, the L3 that are in mode of operation can all not extinguish, and have improved safety performance.
The utility model is that the technical scheme that its technical matters of solution adopts is: a kind of automotive lighting circuit is provided, comprise power Vcc, beam deflector switch and relay, wherein, the anodal wire fuse F1 that connects of described power Vcc, behind the F2, be connected respectively to an end of left headlamp and right headlamp, the other end of described left headlamp and right headlamp is behind beam deflector switch, be connected to the power Vcc negative pole, described power Vcc negative pole is public terminal, described relay the first terminal is connected between wire fuse F1 and the left headlamp, described relay the second terminal connects the power Vcc negative pole behind beam deflector switch, described relay the 3rd terminal connects beam deflector switch, and described relay the 4th terminal connects public terminal.
Above-mentioned automotive lighting circuit, wherein, described left headlamp comprises in the vicinity light modulation L1 and left country beam L2, described right headlamp comprises right passing light L3 and right country beam L4.
Above-mentioned automotive lighting circuit, wherein, full beam indicator lamp L connects between described left country beam L2 and the public terminal.
Compared with prior art; the utlity model has following beneficial effect: the automotive lighting circuit that the utility model provides; left headlamp carries out overcurrent protection by wire fuse F1; right headlamp carries out overcurrent protection by wire fuse F2; when if the head lamp circuit breaks down; country beam L2, the L4 or passing light L1, the L3 that are in mode of operation can all not extinguish, and have improved safety performance.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the schematic diagram of existing automotive lighting circuit;
Fig. 2 is the schematic diagram of a kind of automotive lighting circuit of the utility model.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with embodiment and accompanying drawing, the utility model is further described:
As shown in Figure 2, the automotive lighting circuit that the utility model provides, comprise power Vcc, beam deflector switch 200 and relay 100, wherein, the anodal wire fuse F1 that connects of described power Vcc, behind the F2, be connected respectively to an end of left headlamp 300 and right headlamp 400, the other end of described left headlamp 300 and right headlamp 400 is behind beam deflector switch 200, be connected to the power Vcc negative pole, described power Vcc negative pole is public terminal, described relay 100 the first terminals are connected between wire fuse F1 and the left headlamp 300, described relay 100 second terminals connect the power Vcc negative pole behind beam deflector switch 200, described relay 100 the 3rd terminal connects beam deflector switch 200, and described relay 100 the 4th terminal connects public terminal.Wherein, described left headlamp comprises in the vicinity light modulation L1 and left country beam L2, described right headlamp comprises right passing light L3 and right country beam L4, full beam indicator lamp L connects between described left country beam L2 and the public terminal, if when the current head lamp that is in mode of operation was country beam, full beam indicator lamp L was lit.
When beam deflector switch switched to the passing light position, the contact of relay 100 was by adhesive, and power Vcc, wire fuse F1, light modulation L1, beam deflector switch 200 and relay 100 form C/LOOPs in the vicinity, and light modulation L1 is lit in the vicinity; Power Vcc, wire fuse F2, right passing light L3, beam deflector switch 200 and relay 100 form C/LOOP, and right passing light L3 is lit.When beam deflector switch switched to the country beam position, the contact of relay 100 was by adhesive, and power Vcc, wire fuse F1, left country beam L2, beam deflector switch 200 and relay 100 form C/LOOP, and left country beam L2 is lit; Power Vcc, wire fuse F2, right country beam L4, beam deflector switch 200 and relay 100 form C/LOOP, and right country beam L4 is lit.
So, automotive lighting circuit provided by the invention, left headlamp (in the vicinity light modulation L1 and left country beam L2) carries out overcurrent protection by wire fuse F1, right headlamp (right passing light L3 and right country beam L4) carries out overcurrent protection by wire fuse F2, when the C/LOOP et out of order of in the vicinity light modulation L1 or right passing light L3, light modulation L1 and right passing light L3 can not extinguish simultaneously in the vicinity; When the C/LOOP et out of order of left country beam L2 or right country beam L4, left country beam L2 and right country beam L4 can not extinguish simultaneously, have improved the safety performance of driving.
In addition, automotive lighting circuit provided by the invention only needs a relay 100, compared with prior art, has reduced cost of product, has improved the competitive power of product.
In sum; the automotive lighting circuit that the utility model provides; left headlamp carries out overcurrent protection by wire fuse F1; right headlamp carries out overcurrent protection by wire fuse F2; when if the head lamp circuit breaks down; country beam L2, the L4 or passing light L1, the L3 that are in mode of operation can all not extinguish, and have improved the safety performance of driving.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
