Embodiment Construction
[0009] An anti-dazzling high beam lamp, the high beam lamp is composed of a constant bright area 11 and an adjustment area 12, the light pattern on the light distribution screen of the high beam lamp is elliptical at 25m before its center, and the constant bright area 11 is in the The light pattern on the light distribution screen is a semi-ellipse below the horizontal axis H-H axis of the light distribution screen. Type constitutes the adjustment area 12, if the high beam is in the open state when the constant light area 11 is always on, the adjustment area 12 at this time is then in the light or extinguished state.
[0010] In GB4599, the light distribution performance of automobile headlights is required on the light pattern on the light distribution screen 25m in front of the reference center of the high beam, such as figure 1 As shown, the H-H axis is the horizontal axis of the center of the light distribution screen, the V-V axis is the vertical axis of the center of the...

The invention relates to the field of automobile lights, in particular to a dazzling-resistant high beam light which comprises a normally-light zone and an adjusting zone. Light shape on a light distribution screen 25 meters in front of the center of the high beam light is an oval shape. Light shape on the light distribution screen of the normally-light zone is a semi-oval shape below a horizontal axis, namely an H-H axis of the light distribution screen, wherein the upper boundary of the normally-light zone is placed in a range of 25cm-0cm below the H-H axis. The rest light shape on the light distribution screen of the high beam light forms the adjusting zone. When the high beam light is in a turned-on state, the normally-light zone is always in a lighted state, at the time, the adjusting zone is in a lighted or extinguished state, the light ray height of the normally-light zone on a road face cannot affect other vehicles and pedestrians, the normally-light zone of the high beam light does not need to be turned off during night driving, the adjusting zone is turned off only during vehicle meeting or overtaking so that other vehicles cannot be affected, and meanwhile a road in front of a vehicle can be lighted, and night driving safety is improved.
Description
technical field [0001] The invention relates to the field of automobile lamps, in particular to an anti-glare high beam lamp. Background technique [0002] When driving at night, when meeting vehicles, or when there is a vehicle driving ahead, it is usually necessary to switch the high beam to low beam. Or when overtaking the vehicle in front, switch to the low beam in order not to cause trouble to the vehicle in front. However, in doing so, there is a contradiction that it is necessary to see as far as possible when overtaking, but the high beam cannot be used, which has certain dangers. Contents of the invention [0003] The purpose of the present invention is to provide an anti-glare high-beam lamp which can illuminate the road ahead without disturbing adjacent vehicles when overtaking. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: a kind of anti-glare high beam, the high beam is composed of a constant b...
