TECHNICAL FIELD

[0001] The utility model relates to a kind of motor vehicle turning illumination technology. BACKGROUND

[0002] When motor vehicle turns at night, the illumination direction of headlamp is forward, so that there is a visual blind area in the side part not illuminated. In the process of motor vehicle turning, the illumination direction of headlamp lags behind the driving direction of vehicle, so that a visual blind area is formed in the direction of vehicle turning.

[0003] In order to weaken the influence of the above-mentioned visual blind area, the following technology appears in the prior art:

[0004] 1. There is a corner auxiliary lighting lamp on high-end vehicle, which directly uses stepping motor to adjust the turning angle of headlamp according to turning information.

[0005] 2. The front fog lamp is modified into a turning auxiliary lighting lamp, which is also achieved by using turning information to control stepping motor to adjust the turning angle of lighting lamp.

Moreover, the linkage switch of turning light and side light is a whole piece, which needs to be re-molded, resulting in high mold manufacturing cost (mold development cost, connector matching cost, research and development test cost, production preparation and other costs).

[0011] 2. The side light is separately connected to vehicle-mounted circuit, and a special switch is provided.

[0012] The defect of this way is:

[0013] ① The side light needs to be turned on separately, and cannot be automatically turned on when the turning light is turned on, so the driver needs to operate two switches (turning switch and side light switch) when turning at night, which is more troublesome and increases the driver's operation burden.

[0014] ② Need to set up a separate connector, with connector matching cost, also need to install space in the vehicle for connector matching, in the vehicle space limited vehicle model needs to change the internal structure, high cost.

[0015] CN200420099324.7 discloses a car lighting device with side light, although it can ensure that the side light is not opened in the daytime, but it needs to be linked with the steering wheel, needs to add a set of mechanical transmission mechanism, also cannot do without circuit modification, the modification of vehicle structure is larger, the overall cost is higher. And, the mechanical structure and size of the steering wheel of different vehicle models are different, when used in different vehicles, different mechanical transmission mechanisms need to be designed and matched, the universality is low.
