Abstract

An emergency lighting controller for automatically regulating the brightness of car head light features that when the filament of the distance-light bulb is burnt off and the filament of the near-light bulb is good, the brightness of headlight can be automatically regulated for emergency lighting.

Description

Emergency lighting controller able to automatically regulate brightness of car headlight

The car light standard of automobile is divided into 2 lamps and 4 lamps, lighting is divided into distance light and dipped beam, automobile most of the time when night running all is to throw light on distance light, therefore the headlight high beam filament of bulb damages easily, approximately has only the 50-60% of dipped beam its service life, when headlight high beam filament damages, when dip filament is also intact, give it up, be not only a kind of waste, and do not having spare bulb or inconvenience more to renew under the situation of bulb rapidly, headlight can only continue to travel under only single or a part of far lighting reluctantly, because the damage of light bulb filament, generally can be not at one time in.At this moment, the illuminance of light obviously reduces, and the visbility of road obviously descends, and car body shows that the width demonstration is unclear simultaneously.Because the lighting deficiency, in addition vehicle body to show that width shows unclear, bring great accident potential for like this night travel safety.

At above these problems, the invention provides a kind of automatic conversion and control function: promptly carry out emergent luminous intensity distribution illumination automatically, guarantee safety traffic; Reduce the bulb loss, reduce maintenance cost.

Below in conjunction with Figure of description, the present invention is elaborated: A is the dipped beam control end among the figure, and B is the distance light control end, D1, D2, D3 are unidirectional conducting control diode, and J1 is the contact normally opened relay, and J2, J3 are contact make-before-break relay, J4, J5 are that dry reed relay is often driven in the contact, and Q1, Q2 are the dry reed relay coil, and C1 is a chemical capacitor, L is left headlight, R is right headlight, and LO is a dipped beam, and HI is a distance light, F is a wire fuse, and B is a battery pack.Its principle of work is such: when headlamp beam switch is in A end (dipped beam) mode of operation, and relay J 1 contact adhesive, electric current is by the normally closed contact of J2, J3, passing light work.When headlamp beam switch was in B end (distance light) mode of operation, the control power supply was by D1, and J1 works on, and controlled power supply control loop of filament formation by D2, D3 and HI lamp simultaneously, made J2, the adhesive of J3 operating contact, country beam work.At this moment electric current makes the contact rapid closing of J4, J5 by Q1, Q2, forms a control loop again, J2, J3 is cheated keep mode of operation eventually.When a certain headlight high beam filament of L lamp or R lamp damaged, electric current by Q1 or Q2, did not make J4 or J5 contact release, J2 or the J3 contact release passing light work that quits work.According to above-mentioned principle of work: when a certain upperbeam filament of automobile damages, and under the dip filament situation also in working order, it can be transformed into the dipped beam work of this headlight automatically, carried out the luminous intensity distribution illumination, make the bulb of scrapping originally obtain again utilizing, reduced the loss of bulb, reached the purpose of saving bulb, standby or inconveniently more renew under the situation of bulb rapidly not having simultaneously, the light that makes this headlight substitutes far lighting as emergency lighting, has replenished the deficiency of road surface brightness, and can demonstrate the width that shows of car body, guaranteed the safety of night running.Especially to four lamp system vehicles, demonstrate the preceence of this product more, when four wherein a part of distance light of headlight damaged, it can make the lighting distribution of light more rationally evenly, and the road visbility is bright more clear, makes night traffic safety more be added with guarantee.

Claims

Emergency lighting controller able to automatically regulate brightness of car headlight of the present invention, at present Der Scheinwerfer mit FernlichtAbblendlichtStandlicht bulb because of after headlight high beam filament damages, and under the dip filament situation also in working order, usually all be scrap need not, exist bulb significant wastage phenomenon, simultaneously in the night running process, when the headlight high beam filament of a certain headlight damages, can only under single only or only some lamplit situation, continue reluctantly to travel, make night traffic safety exist great accident potential and design and develop.Its effect is: when the headlight high beam filament of a certain headlight damages and under the dip filament situation also in working order, it can be transformed into the dipped beam work of this headlight automatically, has carried out the luminous intensity distribution illumination, makes the bulb of scrapping originally obtain again utilizing, reduce the loss of bulb, reached the purpose of saving bulb.Do not having under the standby or inconvenient situation about more changing the bulb rapidly simultaneously, the light that makes this headlight substitutes far lighting as emergency lighting, has replenished the deficiency of road surface brightness, and can demonstrate the width that shows of car body, has guaranteed the safety traffic at night.Its circuit structure is characterised in that: A is the dipped beam control end, B is the distance light control end, the B end is provided with diode D1, D1 is connected with capacitor C 1 relay J 1 dipped beam control end A, J1 is as the general supply control of left and right sides headlight, J1 contact input end power connection, the contact mouth respectively with J2, J3 contact input end connects, relay J 2 is as the far and near light guide of L lamp, J3 is as the far and near light guide of R lamp, the normally closed contact of J2 and J3 is connected with the dipped beam of L lamp with the R lamp, open contact is connected with the distance light of L lamp with the R lamp, be provided with coil Q1 between open contact and the country beam, Q2, J2, the coil input end of J3 is connected with distance light control end B, and mouth is provided with diode D2, D3 and dry reed relay J4, J5.
