Title: LENS FOR AUTOMOTIVE LAMP, AUTOMOBILE HEADLAMP AND AUTOMOBILE
Abstract:
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.
