Problems solved by technology

[0003] However, most of the light passing through the low-beam cut-off line structure of the low-beam primary optical element in the prior art enters from the lower part of the secondary optical element (lens), and the low-beam light and dark light formed after refraction by the secondary optical element The color of the cut-off line is blue, and the dispersion phenomenon is serious, which will cause discomfort to the driver during driving
[0004] Based on the above reasons, the existing technology is difficult to effectively ensure that the color of the low beam cut-off line of the low beam lighting shape is ideal, and the dispersion phenomenon is not serious

Embodiment Construction

[0053] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and the protection scope of the present invention is not limited to the following specific embodiments. .

[0054] In the description of the present invention, it should be explained that the orientation or positional relationship indicated by the terms "front", "rear", "left", "right", "upper" and "lower" is based on the low beam of the present invention. After the primary optical element or the lamp module is installed on the vehicle, it follows the orientation or positional relationship indicated by the orientation of the vehicle in the normal driving state. Specifically, the end where the secondary optical element 2 is located is the front, and the end where the light incident part 101 is located is the rear...

Abstract

The invention relates to an automobile lamp, and discloses a low-beam primary optical element which sequentially comprises a light inlet part (101), a light passing part (102) and a light outlet part (103) from back to front; the light outlet part (103) comprises a main light outlet surface (1031) and a secondary light outlet surface (1032) connected with the main light outlet surface (1031), and a low-beam cut-off line structure (105) is arranged on the secondary light outlet surface (1032); and the secondary light outlet surface (1032) is suitable for refracting light rays emitted to the low-beam cut-off line structure (105) to the front upper side. The invention further discloses a vehicle lamp module comprising the low-beam primary optical element, a vehicle lamp and a vehicle. The low-beam primary optical element is simple in structure, the color of a low-beam light-dark cut-off line can be effectively improved, and the dispersion phenomenon is weakened.

Description

technical field [0001] The invention relates to a car lamp, in particular to a low beam primary optical element. In addition, the present invention also relates to a vehicle lamp module, a vehicle lamp and a vehicle comprising the low beam primary optical element. Background technique [0002] The light distribution pattern of the existing vehicle's lighting light projected on the vertical light distribution screen at 25m in front of the vehicle is divided into low beam lighting light shape and high beam lighting light shape. The low beam lighting light shape is determined by the low beam module in the car light module Forming, the low beam module is usually provided with low beam primary optical elements (such as reflectors, light guides) and secondary optical elements (such as lenses), and the light emitted by the low beam light source passes through the low beam primary optical elements and secondary optical elements in turn. After being emitted, the low-beam lighting li...
