Abstract

The invention discloses an automobile high beam and a design method thereof. The automobile high beam comprises an inner reflection cup and an outer reflection cup. The outer reflection cup is arranged on the outer side of the inner reflection cup in a covering manner to form a composite reflection cup, and a light emitting device is arranged in the inner reflection cup. According to the design method of the automobile high beam, the controllable output light beam angle of the automobile high beam can be achieved, the focus of the reflection cups is determined through a transmission matrix firstly, and the length and opening diameter of the reflection cups are jointly decided by the lighting distance and the output angle. According to the design method, results can be given for different irradiation distances and different irradiation angles through corresponding calculation, flexibility, practicability and pertinence are achieved for actual application, and an LED light source can be efficiently utilized for lighting.

Description

technical field [0001] The invention relates to an automobile high beam lamp and a design method thereof, in particular to a method in which a composite reflector is applied to an LED automobile lamp to realize a controllable output beam angle, and belongs to an innovative technology of an automobile high beam lamp and a design method thereof. Background technique [0002] The high beam is one of the important functional devices on the car. Compared with the low beam, the light of the high beam is emitted in parallel, the light is concentrated and brighter, and it can illuminate higher and farther objects. Generally speaking, the near beam The light can only cover a distance of up to 50 meters in front of the vehicle, while the high beam can reach hundreds of meters or even farther, which is conducive to safe driving at night. [0003] However, the phenomenon of abuse of high beams is quite serious at present. Most high beams have serious glare phenomenon. Improper use of hi...
