Abstract

The intention relates to a light distribution control apparatus of car lamps. The purpose of the invention is to provide a low-cost light distribution control apparatus used for appropriately controlling the light distribution of car lamps configured in pairs. The light distribution control apparatus comprises a camera device (CAM) shooting image of an area in front of a car and a light distribution control unit. According to the image shot by the camera device (CAM), the light distribution control unit detects whether a front car at the area in front of the car. According to the position of the detected front car, the light distribution of the V-LoL of one lamp (RHL) of the coupled lamp (LHL, RHL) is changed. The camera device (CAM) is disposed at a position close to the lamp (V-LoL) in a left right direction.

Description

[0001] technology area

[0002] The present invention relates to a light distribution control device for a lamp that illuminates an area in front of a vehicle such as an automobile, and more particularly to a light distribution control device that detects a vehicle in front of a vehicle and appropriately controls the light distribution. Background technique

[0003] In order to prevent the glare of a preceding vehicle or an oncoming vehicle existing in front of the own vehicle, and to brightly illuminate the area in front of the own vehicle, a technology of controlling the light distribution of the headlight of the own vehicle has been proposed. Patent Document 1 proposes a technique of detecting the vehicle position ahead of the own vehicle, and performing light distribution control in which an additional light distribution pattern is added to a part of the low beam light distribution of the headlights based on the detected vehicle position, that is, By performing light distr...
