Abstract

A safely using method of car headlights with the high lighteness is designed according to the character of the prior road and the speed: the headlights on full beam needs not be shut down completely when the cars meet, through the different distances and places of the front meeting cars, the inductor switches between multiplicate combination types of lighting modes of the headlights on full beam. Because the system increases the speed monitoring and alternates information of met cars (the met cars belong to the same type system), the met cars run much more safe under the light control. The remote control mthod can control the lighting of the car headlight which is shut down.

Description

The safe handling method of high brightness headlight for vehicles

Modern people's eyesight generally descends to some extent, and it is very easily tired to drive under the dim light at night, so efficient highlighted illuminating lamp (generally referring to HID or LED now) is relied on up to habituation by favor more and more.Have this to rely on the serious light pollution that is brought and again safety traffic is produced serious hidden danger, but efficient highlighted car lighting lamp can not be used because of highlighted as a kind of high-tech product.And it is that the high-tech product is served the people that modern society advocates the science and technology thought theory that people-oriented especially, so proposed the efficient highlighted lamp system method of a kind of safe and reliable reasonable use.

Safe and reliable rationally is the eventual objective of auto manufacturing, so will carry out light control scientifically and rationally according to the highroad architectural feature.The Modern China highway is changed in the past many defectives such as pavement roughness, track are narrow, trafficability difference, be that Vehicle Speed is very low, speed is lower when night vehicle intersection especially, so more effective in the past light control device is exactly the manual-lock high beam, open dipped headlights, because the distance that speed is very low, pass through in the unit interval is very short, the road surface meets the reaction that the accident of driver's road pavement is made substantially under the illuminating of dipped headlights, thereby reaches the requirement that safety is passed through.Development construction along with Modern China highway crossing formula, the vehicle of function admirable is also just advanced with older generations' speed of a motor vehicle out of one's imagine, be that the distance passed through in the unit interval is elongated, if vehicle intersection at night is still to close high beam fully, it is unmatched fully relying on the interior very long distance of passing through of dipped headlights short distance illumination and unit interval, especially as the situation down train that does not have light at night, safety can not get ensureing therebetween.

For this reason, according to the characteristic Design of the highroad and the speed of a motor vehicle safe handling method of one cover high brightness headlight for vehicles at night, i.e. needn't close high beam fully during vehicle intersection.Now specify as follows to the headlight for vehicles improvement part:

One, (P=U * I) come the strong and weak variation of corresponding realization light, its purpose is to reduce the scotopic bad reaction of the other side's intersection vehicle driver as far as possible by changing electrical power.

Two, by can changing the adjustment that the focus point diverse location realizes that the different shadow road pavement irradiating widths in light reflection back carry out, its meaning is to change and does not change the luminous flux of unit are when light source is strong and weak to be changed or do not change strong and weak variation of light source and the luminous flux that increases unit are increases irradiation distance.Because the road surface irradiating width is the enhancing of optically focused degree to narrow adjustment leniently, can reduce harmful dazzle to the other side's intersection vehicle driver influence (the road surface irradiating width is according to the actual conditions adjustment).

Three,, allow present single distance light is variable to be changed to similar dipped beam light shape by installing the variation of the corresponding realization upper beam shapes of special device (similar automobile dipped headlight principle) such as telescopic shading catch additional.

Four, by the speed of a motor vehicle change realize light control, its meaning be vehicle at night run at high speed or during low speed driving the driver be different to the requirement of light, control the safety that improves vehicle ' so change corresponding realization light by the speed of a motor vehicle.

Five, can more accurately automatically intersection vehicle light be controlled by the mutual switching system of intersection information of vehicles or the mutual switching system of vehicle and information of road surface, its meaning be vehicle in the process of moving road conditions all changing all the time, the position of intersection vehicle also can change thereupon, the irradiation that is intersection vehicle light road pavement also can differ widely, so intersection vehicle both sides driver also can differ widely to the power of the other side's light, such as the intersection vehicle both sides driver of inner curve and outer curve feels it is diverse to the other side's light, be that the outer curve car light is substantially according to less than the inner curve vehicle, the car light light of inner curve can shine directly into driver's (direct irradiation can produce serious dazzle) of road surface and outer curve vehicle, and the minimizing of the car light light road pavement shadow surface of outer curve at this moment adds that serious dazzle driving environment can be very dangerous, intersection this moment vehicle is by the mutual switching system automatic switchover intersection vehicle light of information, allow outer curve car light intensity of light strengthen weakening simultaneously inner curve car light intensity of light, or change method such as lighting system and allow the intersection vehicle safety pass through.

Six, by the control of throwing light on of the automobile front lamp of modes such as remote control induction after to switch-off, its meaning is that on the way the light is dusky after the vehicle parking at night or does not have under the situation of light to carry out the illumination of far and near distance by the random switch headlight of mode such as remote control induction or each auxiliary lamp, and it is movable to make under the car personnel can also the light in abundance.

Below enumerate wherein basic process: the vehicle of at first sensing forward intersection by inductor, inductor at first sends and allows high beam by the order of bright deepening (how many deepenings is decided on distance between the intersection vehicle), makes the other side who is in the vehicle intersection initial stage dazzle-free (dazzle-free referring to seen the road surface to knowing) here; The intersection vehicle is near-induction device continue to give an order (this apart from according to set in advance from the car situation) more and more, the order high beam carries out the adjustment of self-focus point, and (purpose of adjusting focus point is the width that changes former super broad way face irradiation, strengthens the optically focused degree, further reduce dazzle, this zoom order can be carried out with the deepening command synchronization, can make to become self-brightness sensation and the preceding basically identical of variation between the photophase); The intersection vehicle continues to move ahead relatively, inductor is also stretched anti-dazzling screen (processing of similar dipped headlights principle) and is carried out last effective dazzle and handle the nearer intersection vehicle high beam bullet of giving an order once more, and high beam moment returns to original state when finishing after the whole intersection process.More than be the basic process (conversion process is relevant with control system) of light transformation.Because this system has increased the device (the intersection vehicle belongs to same type system) that the speed of a motor vehicle is monitored and the intersection information of vehicles exchanges mutually, so vehicle is more reliable and secure when light is controlled.
