Problems solved by technology
[0003] The invention designs a vehicle anti-glare 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 pedestrian vehicles, if the high beam is used, it will cause visual damage to the drivers on the opposite side, which is not conducive to traffic safety

Embodiment Construction
[0024] Combine below Figure 1 to Figure 5 , the present invention is further described:
[0025] like figure 1 and figure 2 Shown, a kind of vehicle anti-glare headlamp, it comprises ellipsoid reflector 2, light source 1 placed in the first focus of ellipsoid, the baffle plate placed in the second focus of ellipsoid and the motor that drives it to rotate (Fig. Not shown in), the projection lens 5 placed in front of the baffle (the fixed baffle 3 and the movable baffle 4).
[0026] The light emitted by the light source 1 is reflected by the reflector 2, part of the light reaches the baffle and is reflected and absorbed but cannot reach the inner surface of the projection lens 5, and the other part of the light is refracted by the projection lens 5 and then emitted to the front, and then forms a specific light on the 25m virtual light distribution screen. light type.
[0027] According to the road conditions, the detector detects whether there is a vehicle in front of the ...

The invention relates to an anti-dazzling headlamp of a vehicle. The anti-dazzling headlamp comprises a light source (1), a reflecting mirror (2), barriers and a projection lens (5). The reflecting mirror (2) is provided with an elliptical surface, the light source is arranged at a first focal point of the reflecting mirror (2), the barriers are arranged at a second focal point of the reflecting mirror (2), and a focal point of the projection lens (5) coincides with the second focal point of the reflecting mirror (2). The anti-dazzling headlamp is characterized in that the barriers include a fixed barrier (3) and movable barriers (4), the fixed barrier (3) is fixedly connected with a front headlamp body, and a rectangular hole (31) is formed in the fixed barrier (3), so that a part of light rays can be transmitted through the rectangular hole (31), an overhead illuminating effect can be realized for a driver, and high-position guideboard information on two sides of a road can be clearly identified. The anti-dazzling headlamp has the advantages that the light rays can be rotationally shaded by the movable barriers (4) with different sizes and in different shapes, a road front can be illuminated to furthest extent by another part of the light rays which form a changed shape, and dazzling can be prevented for vehicles in the same direction with the vehicle with the anti-dazzling headlamp, opposite vehicles and pedestrians on the road.
Description
technical field [0001] The invention relates to the field of automobile lamp lighting, in particular to a vehicle anti-glare headlamp. Background technique [0002] The car headlight system is mainly composed of low beam and high beam. The high beam is to illuminate the road and road sign information as far as possible within the brightness range stipulated by law. On the other hand, it must also take into account It will not cause glare to oncoming vehicles, vehicles driving in front or pedestrians. 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. For driving safety, high beams are rarely turned on on general urban roads. Contents of the invention [0003] The invention designs a vehicle anti-glare headlamp, which solves the technical problem that the light distribution pattern of the low beam of the automobile he...
