Abstract
The utility model discloses an electronic automatic changer for high beam and low beam of an automobile headlight. The utility model belongs to the technical field of a vehicle lighting device capable of changing the high beam and the low beam or a signal device. The utility model can solve the problem that when the automobile runs in meeting way, the light is dizzy so as to form the lighting blind zone and the utility model can make the road obtain the adequate illumination when the automobile is in direct movement and turning movement. The utility model has advantages of simple structure, low cost, and strong applicability. The utility model is suitable for automobiles or other vehicles. The beams from the automobile headlight can be changed automatically and the utility model has sensitive and reliable and light-operated function. The utility model can substitute the manual-control converting operation of the driver and the utility model can ensure running safety. The utility model is characterized in that an emitter can trigger integration circuit which is composed of an amplifier circuit, a gain saturation circuit, a contact circuit for high beam and low beam, a function converting circuit, and a load circuit.
Description
The utility model belongs to car lighting or the signalling apparatus technical field that high-low beam is arranged.
During automobile night running meeting; two cars are operated instant and near light by chaufeur and are become light in the intersection process; usually can form light from the intersection car to this process of back of giving another the right of way dazzles the eyes; cause the blind area; for keeping clear visual field chaufeur to need accurate operation; but, cause traffic accident easily because of busy, tired or other reason error.
The purpose of this utility model is to provide a kind of automobile front far and near photoelectron automatic switch.When solving automobile meeting and travelling light dazzle the eyes, the problem of lighting blind zone, make the road of automobile when keeping straight on and turning to all obtain adequate illumination.
The utility model is realized with following mode: feature is that it triggers amplifying circuit, gain saturatiuon circuit, far and near light contact circuit, function conversion circuit and load circuit by emitter and constitutes integrated circuit; The connecting relation of each parallel circuit is: emitter triggers amplifying circuit and connects with the gain saturatiuon circuit; Load circuit triggers amplifying circuit with emitter and connects, and also connects with far and near light contact circuit, and far and near light contact circuit connects with function conversion circuit.Described emitter triggers amplifying circuit by optical sensor BG
