Abstract
The anti-dazzling vehicle lamp is designed for eliminating dazzling light during meeting. The anti-dazzling vehicle lamp has the structure comprising reflecting cup, light source fixed inside the reflecting cup, front lampshade and upwards concave reflector below the light source. Owing to the curved reflector and the front deformed lens lampshade, most light beams are reflected to front ground, and this avoids the dazzling light during meeting and raises the illuminance of the front road, resulting in raised safety. In addition, the present invention raises the lighting efficiency of vehicle lamp, too.
Description
Technical field
The present invention relates to a kind of car light, specifically a kind of dazzle-free car light.
Background technology
Existing car light mainly is to be fixed with emitting bulb in the parabolic type reflection shield, is fixed with the transparent glass cover in the place ahead of reflection shield.The light that car light sends illuminates the place ahead of driving through reflection shield optically focused and reflection.But the light that impinges upon reflection shield the latter half can penetrate after the reflection shield reflection obliquely upward.When two cars at a distance of 200 meters during with interior meeting, because the intensity of light reflection of square car light irradiation behind the object far is weaker than the intensity of the light that the other side's car light direct irradiation comes, therefore direct directive both sides driver's eyes of this part light that penetrates obliquely upward that sends by the other side's car light, form dazzling illumination, cause the driver can't see road conditions and other peripheral situation on the road surface, the place ahead of own car light irradiation clearly.In the moment of two car intersections,, literally in the dark dark because suddenly disappearing of the dazzling high light of the other side's automobile can make the driver produce of short duration vision disappearance.The traffic accident that is caused during automobile meeting, be mostly at this moment, former thereby produce thus.Simultaneously, also therefore cause driver's spiritual high-pressure easily when drive night, thereby increase the weight of driver's visual fatigue and mental fatigue.In addition, this part light of She Chuing obliquely upward, owing to can't form effective irradiation to road surface, the place ahead and road conditions, thereby also caused the loss of luminous energy.
Summary of the invention
Purpose of the present invention will design a kind of dazzle-free car light exactly, directly shine the light of dazzling the eyes in the time of meeting can being eliminated after on motor vehicle, installing and using to driver's eyes, improve the security of driving at night and meeting, and reduce the luminous invalid loss of car light, improve the utilization rate of luminous energy.
The object of the present invention is achieved like this: be fixed with light source in reflection shield, the front end of reflection shield is equipped with lampshade, adds concave upright curved surface reflector below light source.
Send the light of directive different directions by light source, the angle of the reflection ray after the reflection shield reflection also has nothing in common with each other.With the axial vertical plane of reflection shield at the light source point place is the boundary, and the part that the light that light source sends shines outside the vertical plane, the reflection shield axis is following after the reflection shield reflection, can penetrate with the angle of oblique top.This part light is the important component part of dazzling the eyes light.The present invention is by after installing the curved surface reflector additional below the light source, aforesaid this part light can be reflexed on the above inwall of the axis of reflection shield, after the reflection of the top of reflection shield, can penetrate to the front lower place of car light again.Like this, car light of the present invention is after light source illuminates, and the original light that oblique upper reflected outside car light of great majority are understood the front lower place of Lamp for indicating change of drive direction, and no longer shine directly into the eyes of the driver on the other side's vehicle.Avoided original car light when meeting, to dazzle the eyes situation thus to what the driver caused.And car light of the present invention will have this part aerial light of directive in the car light now, be transformed into oblique front lower place and penetrate, shine road surface, the place ahead, also make illuminance increase to the road surface, make the driver understand road conditions and peripheral situation better, the generation of contingency when reducing driving.In addition, car light of the present invention not only can be eliminated the most light of dazzling the eyes, but also has reduced the luminous invalid loss of car light, has improved the effective rate of utilization of car light luminous energy.
Curved surface reflector in the car light of the present invention is the semi-cylindrical reflector preferably, so that the car light light source is reflexed to reflection shield top equably to the light of reflection shield lower transmission, makes the illumination of car light front lower place even as far as possible.The front end extended position of curved surface reflector should be positioned at light source at least to the line in forward position, reflection shield lower end.Only in this way, the light of light source directive reflection shield bottom all could be blocked, and reflex to reflection shield top.
The present invention can also realize like this: the lampshade of car light is made for planoconvex spotlight, and for reducing the thickness of planoconvex spotlight, the present invention also designs a kind of planoconvex spotlight of equivalence, the outer surface that is the planoconvex spotlight lampshade is the plane, the axial longitudinal section indention of inner face, towards the vertical outerplanar in one side of lens axis, another side tilts in each sawtooth.The hypotenuse inclination angle of each sawtooth reduces successively by sawtooth order from outside to inside.
The design philosophy that installs planoconvex spotlight formula lampshade on car light of the present invention additional is: though by installing the curved surface reflector additional, the light of the downward irradiation of sending in the car light light source upwards can be reflexed to reflection shield, again through reflection shield reflection back to the ejaculation of the front lower place of car light.But, the light that light source sends to the front upper place, still some is directly to pass lampshade without reflection shield, directive car light the place ahead, light source place are above water.This sub-fraction light is direct directive driver's eyes still, and the aerial also invalid light of light of this part directive, still have the waste of luminous energy.And the character of planoconvex spotlight to be the scattered light that the spot light that is positioned at its focus can be sent pool collimated light beam, if spot light from the lens focus position is upwards vertical move a segment distance after, angle of the parallel rays that converges deflection downwards.The size of deflection angle, it equates with the angle of central line of lens to move the back with spot light.Utilize this optical principle, lampshade is made the form of planoconvex spotlight, light source is located at the place, focus top of planoconvex spotlight, and so just the light of the oblique top that light source can be sent is folded to the front lower place, and the light of dazzling the eyes of car light is all eliminated.But the structures shape of common planoconvex spotlight its volume and thickness excessive, practical application in car light is difficult, thereby planoconvex spotlight carried out equivalent deformation, have only about 2mm but still have anamorphote with the identical reflective functions of planoconvex spotlight thereby form thickness.Its equivalent deformation principle describes in detail in the back.
The present invention can also realize like this: the reflection shield inner surface is bent into a plurality of tiny reflective conical surfaces.This is because the light that sends from light source, wherein most of directive reflection shield, or reflexed to the top of reflection shield through the curved surface reflector, be refracted to the front lower place of car light again through the lampshade lens through the light of reflection shield reflection.The inner surface of common reflection shield is the curved surface of rounding off, and light source and nonideal spot light.So after reflection shield focus and light irradiation,, can penetrate to car light the place ahead through the reflection of reflection shield near the place; And the part light of off-focal penetrates, and behind the directive reflection shield, will form and diffuses.Though after lampshade lens refractions, some can directive ground, in its illumination zone to illuminate the uniformity relatively poor.The present invention improves design to reflection shield, with original reflection shield inner surface, is made for the assembly of a plurality of tiny taper seats that join successively, forms the little reflecting surface of a plurality of tapers.So just can overcome the diffuse reflection phenomenon effectively, reflection ray is reflected in an orderly manner according to the imaging law of level crossing, thereby become, the brightness of illumination of car light front lower place is significantly improved according to effective sunlight to the car light front lower place.Because the angle of inclination of the little reflecting surface of each taper gradually changes, optical characteristics according to level crossing, the angle of the light that the little reflecting surface of each taper is reflected diminishes successively, therefore can make the brightness of illumination of car light road pavement of the present invention be equally distributed state from the close-by examples to those far off, it illuminates the uniformity and can be significantly improved.

The specific embodiment
As shown in Figure 1, distortion lampshade lens 2 are housed, in reflection shield 1, are fixed with light source 4, below light source 4, add concave upright curved surface reflector 3 at the front end of reflection shield 1.Curved surface reflector 3 is the semi-cylindrical reflector, and light source 4 is positioned on the axial line of curved surface reflector 3 (shown in Figure 2).The front end of curved surface reflector 3 is positioned at light source 4 to the line in forward position, reflection shield 1 lower end.The inner surface of reflection shield 1 is formed by connecting by a plurality of tiny conical surfaces.
As Fig. 3-shown in Figure 6, distortion lampshade lens develop by following steps:
1, as shown in Figure 3, planoconvex spotlight is divided into multistage with horizontal line.
2, the flat side of each section of planoconvex spotlight is parallel close to convex surface, form the variant of planoconvex spotlight shown in Figure 4.
3, will go up that each section in the gained lens variant moves to right in the step, make the flat side alignment of each section, form the straight line limit again, obtain the anamorphote that convex surface shown in Figure 5 is dentation thus.These lens are identical with former planoconvex spotlight to the effect of converging of light, and its thickness will be much smaller than former planoconvex spotlight.This anamorphote can be installed and used on the car light lampshade, but the cambered surface on each profile of tooth of lens convex surface has certain manufacture difficulty.
4, for solving the cambered surface manufacture difficulty, the cambered surface approximate processing on each segment of above-mentioned anamorphote is become the plane, can obtain zigzag distortion planoconvex spotlight shown in Figure 6 thus.
This zigzag anamorphote has the equivalence of higher degree to the effect of converging of light with former planoconvex spotlight, and is easy to processing.Because therefore its less thick is more suitable in installing and using on car light.
Zigzag distortion planoconvex spotlight needs to calculate one by one the profile angle of each tooth during fabrication, and the computational methods of each profile angle are as follows: as shown in Figure 7, establishing profile angle is x, and incident ray and horizontal angle are α, and the refractive index of lens material is γ, then
sin(x+α)/sinx＝γ
Be tanx=sin α/(γ-cos α) wherein, the α value can be outerplanar apart from f apart from lens according to light source, and the distance h on line-spacing profile angle summit, lens centre comes surely, its pass is
Tan α=h/f and the value of material refractive index gamma can be found from " refraction counting rate meter ".
The first half of the inner surface of reflection shield 1 is formed by connecting by a plurality of tiny reflective conical surfaces among the present invention.Its design philosophy is as follows:
Begin from first the little reflective conical surface that joins with zigzag distortion planoconvex spotlight, the angle of this conical surface and the angle of horizontal direction should be between 0-45 °, if greater than 45 °, then the light that sends from light source can not penetrate after reflection, does not reach the purpose in irradiation the place ahead.When the angle of this little reflective conical surface and horizontal plane was between 0-45 °, angle is big more, and was also big more through the angle on its light reflected and ground.Be that the light that sends of light source is more concentrated to the light ratio on closer distance road surface before the motor vehicle after reflection; Otherwise it is then opposite.Determining of concrete angle can be determined flexibly according to the difference of car light setting height(from bottom) on the different vehicle.
Determining of follow-up other the little reflective conical surface angle of reflection shield inner surface depends primarily on predetermined reverberation in incoming position on the anamorphote and the size between the incidence zone.Predetermined incoming position is the closer to the center of lens, and the light overlay region, shop on road surface, the place ahead is more little, and the uniformity of shop light is also just high more; More little between predetermined incidence zone, the shop light uniformity is also just high more.After the angle of each little reflection conical surface was determined, its radical length was relevant in the distribution situation on road surface with light reflected.Radical length is long more, and the scope that this reflective surface reflection ray shines the road surface is just big more, and is also just big more to the light overlay region, shop on road surface, the place ahead.When reflecting surface is tiny to a certain degree the time, all reflective surfaces constitute approximate smooth curved surface.
In conjunction with Fig. 8, the design principle of each little reflective conical surface is as follows in this reflection shield:
