Abstract
(EN)
A lens for an automotive lamp, an automobile headlamp and an automobile. A lens (1) for an automotive lamp comprises a first lens face (11) and a second lens face (12) opposite to the first lens face (11). The first lens face (11) is a curved surface or a planar surface, and the second lens face (12) comprises a plurality of concentric circle type annular faces. By means of a plurality of annular faces (13) arranged on the second lens face (12) of the lens (1), light achieving parallel incidence in the manner of forming an angle with a horizontal direction may be divided into a plurality of small faces for incidence on the premise of not influencing horizontal parallel light penetrating the lens so as to form focusing, so that light reflected by the lens and light penetrating the lens both may not be focused effectively. By employing the automobile headlamp having the lens, exterior focusing formed by sunlight being reflected by the lens when irradiating the automobile headlamp and interior focusing formed by sunlight penetrating the lens when irradiating the automobile headlamp may be eliminated, and parts located on an inner side and an outer side of the lens in the automobile headlamp are prevented from being damaged by sunlight irradiation.

L’invention concerne une lentille pour lampe automobile, une lampe frontale d’automobile et une automobile. Une lentille (1) pour une lampe automobile comprend une première face (11) de lentille et une deuxième face (12) de lentille opposée à la première face de lentille (11). La première face (11) de lentille est une surface courbe ou une surface plane, et la deuxième face (12) de lentille comprend une pluralité de faces annulaires de types cercles concentriques. Au moyen de la pluralité de faces annulaires (13) agencées sur la deuxième face (12) de lentille (1), la lumière arrivant en incidence parallèle de manière à former un angle avec une direction horizontale peut être divisée en une pluralité de petites faces pour l’incidence sur le principe d’absence d’influence sur la lumière parallèle horizontale pénétrant dans la lentille afin de former une concentration, de sorte que ni la lumière réfléchie par la lentille ni la lumière pénétrant dans la lentille ne soient concentrées efficacement. En employant la lampe frontale d’automobile ayant la lentille, la concentration extérieure formée par la lumière solaire qui est réfléchie par la lentille lorsqu’elle éclaire la lampe frontale automobile et la concentration intérieure formée par la lumière solaire pénétrant dans la lentille lorsqu’elle éclaire la lampe frontale automobile peuvent être éliminées, et des parties situées sur un côté intérieur et un côté extérieur de la lentille dans la lampe frontale d’automobile évitent d’être endommagées par le rayonnement solaire.

用于车灯的透镜、汽车前照灯及汽车。用于车灯的透镜(1)包括第一镜面(11)和与第一镜面(11)相对的第二镜面(12),第一镜面(11)为曲面或平面,第二镜面(12)包括多个同心圆式的环状面。通过在透镜(1)的第二镜面(12)上设置多个环状面(13),在不影响水平平行光线穿过透镜形成聚焦的前提下,能够将与水平方向成角度平行入射的光线分成若干个小面入射,使得经透镜反射的光线和穿过透镜的光线都不能有效聚焦。采用该透镜的汽车前照灯能够消除太阳光照射在汽车前照灯时经透镜反射形成的外聚焦和穿过透镜形成的内聚焦,避免太阳光照射对汽车前照灯内部位于透镜内侧和外侧的零件造成损伤。
