Abstract

The present invention relates to a headlight optical system and a lamp using the same, the headlight optical system is an optical system using a single lens, the system comprises a first incident surface; a second incident plane which is annularly arranged on the periphery of the first incident plane; and a light emitting surface, wherein the inner edge of the second incident plane is connected with the edge of the first incident plane, the second incident plane has an inclination angle, light emitted by a light source is refracted by the first incident surface or the second incident surface to enter the optical system, and then the light is refracted by the light emitting surface to be emitted out. According to the invention, the inclined second incident surface is arranged around the periphery of the first incident surface, so that the brightness is more concentrated, and the edge sharpness of the light-emitting image projected by the light source is improved.

Description

technical field [0001] The invention relates to an optical lighting system, in particular to a headlight optical system and a lamp applied thereto. Background technique [0002] In recent years, the development of automotive systems has focused on safety, performance, and automatic assisted driving, and smart headlights will be one of the communication methods for Advanced Driver Assistance Systems (ADAS). In addition to the electronic communication between systems, advanced driving assistance systems can also use intelligent headlights to provide additional visual assistance functions, such as warnings, important reminders, etc., as a direct and fast communication method between vehicles and people. For example, the known smart headlights utilize the optical design of the array light-emitting characteristics, and through the on-off control of a single lighting area, it is possible to combine multiple small-area lighting unit modules to achieve a warning effect that meets re...
