Embodiment

[0038] Example: such as figure 1 as shown,

[0039] A headlamp with adjustable lighting area, comprising a light source device 1, a control device 3 and a light projection device 2, the control device 3 is arranged between the light source device 1 and the light projection device 2, and the control device 3 consists of a plurality of An array of independent units is combined, and each unit can independently control the passing characteristics of light. The light projection device 2 projects the light transmitted by the control device 3 .

[0040] In the above scheme of this embodiment, a control device 3 is provided between the light source device 1 and the light projection device 2. The control device 3 is composed of a plurality of independent unit arrays, and each unit can independently control the passing characteristics of the light. By controlling The passing characteristics of each unit lead to the formation of different shapes by the control device 3. Therefore, in th...

Abstract

The invention relates to the technical field of illumination, in particular to a headlamp with an adjustable illumination area. The headlamp comprises a light source device, a control device and a ray casting device. The control device is arranged between the light source device and the ray casting device and formed by combining a plurality of independent units in an array, and each unit can independently control the passing characteristic of rays. The ray casting device casts the rays transmitted from the control device. According to the scheme, the control device is arranged between the light source device and the ray casting device and formed by combining the multiple independent units in the array, each unit can independently control the passing characteristic of rays, and then rays passing through the control device form different shapes by controlling the passing characteristic of each unit. Therefore, in the actual work state, different illumination areas can be obtained for the headlamp according to the illumination requirements under actual conditions, the driving safety is improved, and the application range of the headlamp is widened.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a headlight with adjustable lighting area. Background technique [0002] In the field of automotive lighting technology, the state has announced GB7454-87 "Technical Planning for the Use and Light Adjustment of Motor Vehicle Headlamps", GB4599-2007 "Light Distribution Performance of Headlamps" and GB4660-2007 "Fog Lamps with Filament Bulbs for Automobiles" 》Present clear requirements on the luminous intensity and irradiation direction of high beam lighting, low beam lighting and fog lamps of motor vehicles. [0003] In the current headlight structure, in order to adapt to different use environments, it usually includes a dipped beam and a high beam. [0004] For the low beam of the headlights, in order to avoid the light from hitting the passing vehicles and pedestrians on the roadside, it is required that the emitted light must form a clear cut-off line, and for the formation ...
