Problems solved by technology

However, a separate configuration of the far-field brightness enhancement device requires high assembly accuracy requirements during assembly, otherwise it will easily affect the accurate combination of the far-field light shape and the low-beam light shape. In addition, the separately configured far-field brightness enhancement device requires an independent optical Components take up more space, are not easy to arrange and cost more

Embodiment Construction

[0024] The present invention will be further described below in conjunction with the examples, but it is not intended to limit the present invention.

[0025] please combine Figure 1 to Figure 4 As shown in the figure, the lighting device for enhancing the far-field brightness of the low-beam headlight of an automobile involved in this embodiment includes a low-beam lens 1, a shading plate 2, and an LED far-field light source 3 (in this embodiment, there are three light sources 301, 302 and 303). ), far-field light source condensing element 4, reflector 5 and LED low-beam light source 6, LED far-field light source 3 and LED low-beam light source 6 are both 3-chip light sources.

[0026] In this example, the condensing elements 4 of the far-field light source are three condensing cups corresponding to the LED far-field light source 3. The condensing cups 4 are solid bowl-shaped structures. The rear end of the bowl is provided with a bowl-shaped concave cavity, the diameter of...

Abstract

The invention discloses an illuminating device for enhancing far-field brightness of automobile low-beam headlights, which comprises a low-beam lens, a shading plate, a far-field light source, a condenser cup, a reflector, and a low-beam light source. The low-beam lens and the shading plate are arranged on In front of and below the opening of the reflector, the far-field light source and the condenser cup are arranged on the top of the opening of the reflector and above the shading plate. The light is reflected by the reflector and passes through the low beam lens to form a low beam light shape. The front edge of the visor forms a far and near light cut-off line. The front end of the condenser cup faces the ellipsoidal surface. The reflector reflects and passes through the low beam lens to form the far field light shape superimposed on the low beam light shape. The light shape of the near beam and the light shape of the far-field light of the present invention are well combined, reduce optical elements, occupy less space, and have high optical efficiency.

Description

technical field [0001] The invention relates to an automobile lighting device, in particular to a lighting device for enhancing the far-field brightness of a low-beam headlight of an automobile. Background technique [0002] In the process of driving, the vehicle inevitably needs to use the safety lighting device lights. The lights are very important for the safety of driving at night, and the range of the lighting is the focus of the driving safety. With the development of automobile technology, more and more automobile headlight systems are equipped with new lighting function modules: far-field brightness enhancement device, whose main function is to illuminate the area of ​​the far-field near the border of the low beam and expand the front of the driver. The visible area of ​​​​the vehicle is realized, and the lighting of the vehicle is very far and wide, and the safety of the whole vehicle is improved. However, if the far-field brightness enhancement device is configure...
