Problems solved by technology

[0002] Due to the advantages of high brightness and long irradiation distance of LED lights, more and more LED lights are used as high-beam / low-beam lights on motor vehicles on the market; when using LED light sources, generally LED direct light and convex lens light distribution Combination, although this combination has a good appearance, it cannot obtain a wide road light pattern in the front, rear and left and right directions, and the edge of the road light pattern is prone to blue light when the lens is distributed, which is likely to affect the driver's judgment when driving

Abstract

The invention discloses a motor vehicle LED headlamp device and a motor vehicle thereof. The motor vehicle LED headlamp device comprises: an LED light source; a reflecting mirror positioned on the light path of the LED light source; and a lens located on the path of the emergent light of the reflector, wherein the lens is provided with light emitting parts with the same wall thickness, and the light emitting parts have radians protruding outwards. Light is emitted from the LED light source, is reflected by the reflecting mirror and finally penetrates through the lens with the equal wall thickness to be emitted out, the light is reflected by the reflecting mirror, the light can be integrated, and therefore the wide road surface light pattern in the front-back direction and the left-right direction can be obtained in the light distribution process. The lens with the equal wall thickness is adopted, so that the lens does not have a light distribution effect when light penetrates through the lens, and the problem that blue light appears on the edge of a road surface light pattern during light distribution of the convex lens is solved.

Description

technical field [0001] The invention relates to the field of motor vehicle lights, in particular to a motor vehicle LED headlight device and a motor vehicle. Background technique [0002] Due to the advantages of high brightness and long irradiation distance of LED lights, more and more LED lights are used as high-beam / low-beam lights on motor vehicles on the market; when using LED light sources, generally LED direct light and convex lens light distribution Combination, although this combination has a good appearance, it cannot obtain a wide road light pattern in the front, rear and left and right directions, and the edge of the road light pattern is prone to blue light when the lens is distributed, which is likely to affect the driver's judgment when driving. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the present invention proposes an LED headlight device for motor ve...
