Description
Technical field
The present invention relates to a kind of catoptron, be specifically related to a kind of soft light enhancement anti-dazzle reflecting mirror, be a kind of interference cooperative effect principle of multi-layer nano film and the mirror assembly of selective control light reflectance, be particularly useful for glareproof mirror as the vehicles.
Background technology
Along with the development of society, rearview mirror is as the important safety attachment of automobile, and its performance requirement is also more and more higher.There are some disadvantages in traditional rear-view mirror, as reflectively dazzle the eyes, misty rain is fuzzy and dust contamination etc.According to statistics, in China, because the traffic hazard that the rearview mirror defective causes accounts for 30% of traffic hazard sum; In the U.S., this ratio is 20%; On highway, this ratio is then up to 70%.In these rearview mirror defectives, reflective harmfulness maximum of dazzling the eyes, it can not only make the people cause of short duration yctalopia, increase braking distance, and easily causes driver's fatigue for a long time.Experiment test proves that with the average braking Distance Calculation of 97km/h, braking distance is 42m during free from glare, is 80m when dazzle is arranged, and has totally had more one times.This shows that anti-dazzle is for driver's importance.
Consumer's (driver) strong appealing has caused the attention of countries in the world automobile dealer height, has all dropped into a large amount of man power and materials at present more feasible technology and technology are improved, and advanced in performance rearview mirror new product appears on the market one after another.Wherein, with dielectric sandwich type glareproof mirror market share maximum.This rearview mirror anti-glare technology is a folder dielectric low light level gel between two blocks of glass, the bright-dark degree that changes the control rearview mirror by the power of electric current.Two photoelectric sensors are housed on the automatic anti-glare rearview mirror detect back car light light intensity automatically, when intensity surpasses the dazzle standard of setting, then by switching on to glass mirror, make it become blackish green by normal bright state, thereby specular reflectance is descended, reach the purpose of eliminating dazzle.When light source away from after, stop the energising, rearview mirror then becomes normal bright color again.From it principle of work we as can be seen this rearview mirror still have some self defective.At first, this rearview mirror is to eliminate dazzle by the colour of lens deepening, after the colour of lens deepening, also cause eyeglass that the reflectivity of light is reduced when eliminating dazzle, sharpness descends, make the driver can't clearly see road, pedestrian and the vehicle of back clearly, thereby lost the effect of rearview mirror as automobile important safety annex.Secondly, this rearview mirror need be differentiated extraneous lamp and force light source by photoelectric sensor, will force the equation of light value input photoresistance of light source and extraneous lamp, thereby reach the ability that the eyeglass current switching is injected in control.This design concept influence factor is too many, except external high light, also wait whether control its work by gate light, body light and backup lamp, so this rearview mirror failure rate is higher, back investigation difficulty breaks down, except judging whether glareproof mirror itself has the problem, also to check fuse, body light circuit and backup lamp circuit lamp, maintenance is trouble very.At last, this rear-view mirror complexity, cost is higher.At present, 120 dollars～200 dollars/every of such rearview mirror price is unwell to domestic vast automobile consumption colony.
The anti-dazzle inside rear-view mirror of another money, its anti-dazzle principle are to utilize two reflectings surface of a prismatic lens, and the primary reflection surface that is of reflection plated film is arranged, and its reflectivity is 70%, and the outside surface of glass is a subreflector, and its reflectivity is 4%.When the driver drives by day, rearview mirror is placed the primary reflection surface position, can make the driver clearly see the situation at automobile rear like this.The driver is when night running, can switch the position that handle places rearview mirror subreflector by switching, when the vehicle in high light directive the place ahead of back vehicle, because the reflectivity of subreflector is very little, therefore only there is very small percentage light to be reflected, the high light that other overwhelming majority is dazzle the eyes all falls by the subreflector scattering, thereby has prevented to dazzle the eyes sense because of what emergency light reflex produced.Switch by switching handle two working positions of the major and minor reflecting surface of this glareproof mirror, has increased driver's operational sequence.Simultaneously, because the reflectivity of subreflector is less, the minute surface sharpness descends when driving at night, has influence on traffic safety.
In addition, also have some rearview mirrors behind the visor two-way mirror, to plate TiO
2The isosol product coating, thus realize the purpose (being commonly called as " Lan Jing ") of anti-dazzle, but this coating process is comparatively complicated, adopts sol-gel process to be prepared usually.There are some problems in the rete of this method preparation: 1) cause film to chap easily in drying and the roasting process, even come off; 2) stress influence of film has limited the thickness of film; 3) film thickness and homogeneity are wayward; 4) film quality of the factor affecting such as fluctuation of the viscosity of colloidal sol, temperature, concentration and substrate preparation; 5) adhesion of rete relatively poor (see Chen Hong, Chinese folk art forms, Gao Jinyue, etc. sol-gel process prepares automobile rearview mirror. Physical Experiment, 2004,11:16～18).And difficult control (seeing Chinese patent literature CN2704507) of the aberration of this blue mirror stability.
In sum,, seek a kind of new anti-dazzle method and technology, make it when eliminating dazzle, still can optionally control light reflectance, keep the minute surface sharpness for overcoming some drawbacks of the current glareproof mirror that generally uses; Simultaneously technology is simple, and stable performance with low costly just seems particularly important.
