Problems solved by technology
[0003] The invention designs a vehicle lighting headlamp, which solves the technical problem that the light distribution pattern of the low beam of the automobile headlamp suppresses glare, but its irradiation distance is limited, and it is difficult for the driver to find distant obstacles and For pedestrian vehicles, if the high beam is used, it will cause visual damage to the drivers on the road, which is not conducive to traffic safety

Embodiment Construction
[0022] Combine below Figure 1 to Figure 4 , the present invention is further described:
[0023] A vehicle lighting headlamp, which includes an ellipsoid reflector 1, a light source 2 placed at the first focus of the ellipsoid, a shading column 3 placed at the second focus of the ellipsoid, and a motor driving its rotation (not shown in the figure) out), the projection lens 4 placed in front of the shading column.
[0024] The light is emitted by the light source 2 and reflected by the ellipsoidal reflector 1. Part of the light is blocked by the protrusion on the shading column 3. Part of the light is refracted by the projection lens 4 and then emerges to form a specific light pattern on the 25m virtual light distribution screen.
[0025] According to the road conditions, it detects whether there is a vehicle in front of the vehicle or there is a vehicle coming from the opposite side, and there are pedestrians on the sidewalk on the sidewalk. That is to illuminate the road ...

The invention relates to an illuminating headlamp of a vehicle. The illuminating headlamp comprises a light source (2), a reflecting mirror (1) with an elliptical surface, a shading column (3) and a projection lens (4). The light source is arranged at a first focal point of the reflecting mirror (1) with the elliptical surface, the shading column (3) is arranged at a second focal point of the reflecting mirror (2) with the elliptical surface, a focal point of the projection lens (4) coincides with the second focal point of the reflecting mirror (2) with the elliptical surface, and the projection lens (4) is arranged at the front of the shading column (3). The illuminating headlamp is characterized in that protrusions with different widths and different altitudes are arranged on the shading column (3). The illuminating headlamp has the advantages that specific lighting patterns can be formed by the protrusions with the different widths and the different altitudes when the shading column (3) rotates, so that a road front can be illuminated by lamplight to the furthest extent, and dazzling can be prevented for vehicles in the same direction with the vehicle with the illuminating headlamp, opposite vehicles and pedestrian on a road.
Description
technical field [0001] The invention relates to the field of automobile lamp lighting, in particular to a vehicle lighting headlamp. Background technique [0002] The car headlight system is mainly composed of low beam and high beam. The high beam is to illuminate the front as far as possible within the brightness range stipulated by law. On the other hand, it must also be considered that it will not give the opposite Oncoming vehicles, vehicles driving in front, or pedestrians cause glare. Therefore, the light distribution pattern of the low beam suppresses glare, but its irradiation distance is limited, and it is difficult for the driver to find distant obstacles and pedestrians and vehicles. In the case of high speed, the low beam lighting distance is not far enough, and it is difficult to find obstacles in front of the vehicle. When the high beam is used, it is easy to cause the opposite and front vehicles and pedestrians to be dazzled, reducing driving comfort and safe...
