The specific embodiment
Below, the present invention is described in detail according to the embodiment shown in the figure.In Fig. 1, simplify the structural principle show lamps apparatus for vehicle 1 of the present invention, for example on light source 2, the main inner face mirrors 3 that made up two revolution elliptic reflecting surfaces are installed as based on halogen bulb etc.And in the following description, corresponding all around, going up inferior direction, to be installed in the state of seeing from the driver's seat side under the state on the vehicle with this lamps apparatus for vehicle 1 be benchmark.
As also having illustrated in the above, aforementioned main inner face mirror 3 by two revolution elliptic reflecting surfaces, be right elliptic reflecting surface 3a and left elliptic reflecting surface 3b combination and constituting.When making up, right elliptic reflecting surface 3a and left elliptic reflecting surface 3b are formed centrally symmetry in the center line Z axle of this lamps apparatus for vehicle 1 being.The first focus f2a of right elliptic reflecting surface 3a and the first focus f2b of left elliptic reflecting surface 3b are consistent, and to be positioned at the light emitting source that is configured in the aforementioned light source 2 on the Z axle be on the filament 2a.
Therefore, major axis is arranged in rear, left side (being the right side at Fig. 1) from the second focus f3a of the right elliptic reflecting surface 3a that right side and central shaft z intersect, and the transverse that connects the first focus f2a and the second focus f3a intersects with aforementioned Z axle.And, left side elliptic reflecting surface 3b also forms in the mode identical with right elliptic reflecting surface 3a, the long axis of ellipse of reflecting surface 3b is intersected from opposition side (left side) with the angle identical with the angle of the crossing of the major axis of right elliptic reflecting surface 3a and aforementioned center line Z axle, makes the second focus f3b (not shown) be positioned at oblique rear.
Like this, when some bright light source 2, the light that aforementioned right elliptic reflecting surface 3a is reflected forms the light source picture on the second focus f3a of the right elliptic reflecting surface 3a that is positioned at left reflecting surface 3b side, similarly, the light that reflected of left reflecting surface 3b is gone up at the second focus f3b (not shown) that is positioned at aforementioned right elliptic reflecting surface 3a side and is formed the light source picture.And, at this moment, near the position when preferred each the second focus f3a, f3b are positioned at the external diameter of elliptic reflecting surface of the other side's side as combination principal goods mirror 4 described later.And,,, can not send light towards front face side from outside as the main inner face mirror 3 of convex-shaped even therefore when having lighted light source 2 because each elliptic reflecting surface 3a, 3b be positioned at inner face side yet.
In the present invention, as mentioned above, be provided with the principal goods mirror 4 on the direction of illumination that turns back to this lamps apparatus for vehicle 1 with respect to direction of illumination to the light that opposite direction (rear) is radiated, and corresponding by two forms that form of combination with aforementioned main inner face mirror 3, aforementioned principal goods mirror 4 also constitutes corresponding with two that constitute aforementioned main inner face mirror 3 respectively two in principle.
At this moment, corresponding with the second focus f3a of aforementioned right elliptic reflecting surface 3a, being provided with near extremely close of this second focus f3a or its is that focus and reflection direction are the left parabolic 4b of paraboloid of revolution of vehicle front etc., similarly, corresponding with the second focus f3b of aforementioned left elliptic reflecting surface 3b, be provided with right parabolic 4a.
Here, the focal length of aforementioned left parabolic 4a and right parabolic 4b is freely, for example obtains under the situation of bigger light-emitting area wanting, and should use the long parabolic of focal length for aforementioned parabolic 4a, 4b.And in this case, it is one that aforementioned parabolic 4a, 4b need not, and for example also can the slightly different parabolic of a plurality of focal lengths be provided with differential and connect, to form necessary area and shape.
By such formation, by above-mentioned explanation and Fig. 1 as can be known, lamps apparatus for vehicle 1 of the present invention is different with existing lamps apparatus for vehicle, aforementioned elliptic reflecting surface 3a, 3b have formed from the shape of the place ahead ambient light source 2, therefore 2 lamp holder and the gap at the rear between elliptic reflecting surface 3a, the 3b emit to the outside light that is reflected by above-mentioned elliptic reflecting surface 3a, 3b towards oblique rear from light source, then, turn back on the direction of illumination by aforementioned parabolic 4a, 4b.
And the second focus f3a of right elliptic reflecting surface 3a is set on the extended line of left elliptic reflecting surface 3b or near it, and the second focus f3b of left elliptic reflecting surface 3b is set on the extended line of right elliptic reflecting surface 3a or near it.At this moment, near the position of elliptic reflecting surface that preferred each the second focus f3a, f3b are positioned at the other side's side during as combination principal goods mirror 4 described later, in the time of particularly on being set in the extended line of elliptic reflecting surface, then can increase the size of main inner face mirror 3 and improve the utilization ratio of light, and realize the miniaturization of light fixture integral body.And the central shaft Z and the second focus f3a and f3b are in the same plane, thereby realize the miniaturization of light fixture.
Therefore, vehicle according to the invention can all capture the light of radiation beyond the lamp holder that speculum can not be set originally basically with light fixture 1, so has improved the light catch rate for light source 2.And, by two aforementioned elliptic reflecting surface 3a, 3b that combine, therefore light is assigned on the both direction equably, has obtained two light-emitting areas by a light source, for example in the vehicle that as cart etc., only uses a lamps apparatus for vehicle 1, also can increase light-emitting area.
And, can not produce light towards the front face side of main inner face mirror 3, can directly not see light source 2 from the outside.And, light from about reflecting surface reflection, bring as the impression that individually is provided with as the light source fluorescent tube.Thereby even particularly disposed under the situation of a lamps apparatus for vehicle at the middle body at vehicle as cart etc., a light source seems also to light as left and right symmetrically.
Fig. 2 is the front view of the example of the mode of expression when carrying out actual implement of lamps apparatus for vehicle 1 of the present invention, in Fig. 1 for the reduced representation structure, for passing through at a light source 2, the example of the lamps apparatus for vehicle 1 that is made of 4 combinations of a concave mirror 3 and a pair of principal goods mirror is illustrated, but this structure is difficult to reduce the light towards the top, as a result, the light quantity of being blocked by shadow shield etc. increases, and correspondingly can not get light quantity increases effect.
Therefore, in the present invention by being that the main inner face mirror of concave mirror is divided into a plurality of that below haply makes progress with inner face, make the light beam of emitting to the outside become light beam narrower on the above-below direction from a concave mirror, and, realized that light quantity on the whole increases by reducing the shading amount of shadow shield 9 (9a).
In Fig. 2, label 3 is that main inner face mirror (top concave mirror), label 4 are that principal goods mirror, label 5 are that bottom concave mirror (the main inner face mirror of downside), label 6 are that bottom object lens, the label 7 corresponding with the bottom concave mirror is that top concave mirror, label 8 are that top object lens, label 9 and label 9a are shadow shields.Main inner face mirror 3 is shared the light of about at the most 1/4 in the light that light source 2 produces respectively by above-mentioned right elliptic reflecting surface 3a and left elliptic reflecting surface 3b.Bottom concave mirror 5 has right elliptic reflecting surface 5a and left elliptic reflecting surface 5b similarly, and shares the light of about at the most 1/4 in the light that light source 2 produces respectively.
And bottom concave mirror 5 is to compare with elliptic reflecting surface 3a, the 3b of main inner face mirror 3, first focus of each elliptic reflecting surface 5a, 5b and the shorter less reflecting surface of the focal length between second focus.Because less than distance between the focus of the elliptic reflecting surface of the main inner face mirror 3 on top, it is overlapping to be configured to corresponding object lens position.For example can be set at object lens are positioned at the pattern as shown in Figure 2 of upside greatly along with the lateral separation change of the aforementioned central shaft Z of distance lamps apparatus for vehicle.And on the contrary,, also can be set at the lamps apparatus for vehicle that is positioned at downside as object lens successively on the contrary if increase distance between focus.
Bottom concave mirror 5 is by two revolution elliptic reflecting surfaces, and promptly right elliptic reflecting surface 5a and left elliptic reflecting surface 5b combine.When making up, right elliptic reflecting surface 5a and left elliptic reflecting surface 5b are that the center forms symmetrically with the center line Z axle of this lamps apparatus for vehicle 1.The first focus f5 of the first focus f5a1 of right elliptic reflecting surface 5a and the first focus f5b1 of left elliptic reflecting surface 5b is consistent, and to be positioned at the light emitting source that is arranged on the aforementioned light source on the center line Z axle be on the filament 2a.
The second focus f5a2 of right reflecting surface 5a is positioned at the rear, left side, and the transverse that connects the first focus f5a1 and the second focus f5a2 intersects with aforementioned central shaft Z.And left elliptic reflecting surface 5b also similarly forms with right elliptic reflecting surface 5a, with the identical angular cross of the aforementioned angle of the crossing of the major axis of right reflecting surface 5a, make the second not shown focus f5b2 be positioned at oblique rear.In addition, bottom concave mirror 5 is compared with top concave mirror 3, and the distance between first focus and second focus is shorter.That is, the distance between f5a1 and the f5a2 is shorter than the distance between f2a and the f3a, and bottom concave mirror 5 more is provided with near light source 2 ground than top concave mirror 3.
And, in the object lens of bottom, have: corresponding with right elliptic reflecting surface 5a and with this second focus f5a2 or its extremely close near be that focus and reflection direction are the left parabolic 6a of paraboloid of revolution of vehicle front etc.; And it is corresponding with left elliptic reflecting surface 5b and be that focus and reflection direction are the right parabolic 6b of paraboloid of revolution of vehicle front etc. with this second focus f5b2.
And top concave mirror 7 has elliptic reflecting surface 7a, this elliptic reflecting surface 7a catch towards the scope of catching than aforementioned main concave mirror 3 more the rear the direction radiation, from the light of light source 2, incide top object lens 8 then and reflection forwards, form irradiates light.And, in the present invention, constitute each (right, a left side) elliptic reflecting surface 3a, 3b, 5a, the 5b of main concave mirror 3, bottom concave mirror 5 and the top concave mirror 7 of above-mentioned explanation, first focus of 7a, 7b is set on the filament 2a that all is positioned at light source 2 as shown in Figure 1, therefore light source 2 is roughly whole on every side by 3,5,7 encirclements of each concave mirror, thereby improves the light catch rate easily.
Fig. 3 and Fig. 4 schematically show each concave mirror 3,5,7 that above-below direction as described above cuts apart and the corresponding relation between each object lens 4,6,8 and shadow shield 9, the 9a effect etc. to it, Fig. 3 mainly shows the reflected light path between each reflecting surface, and Fig. 4 mainly shows the configuration of each reflection.At first, the light of right elliptic reflecting surface 3a that arrive to constitute aforementioned main concave mirror 3 from the light that light source 2 is emitted is because aforementioned light source 2 is first focuses and after temporarily converging on the second focus f3a of this right side elliptic reflecting surface 3a, arrive the left parabolic 4b of principal goods mirror 4.
At this moment, with the hand-to-hand position of the second focus f3a of aforementioned right elliptic reflecting surface 3a, be preferably the position that is no more than 1mm, be provided with shadow shield 9, and this shadow shield 9 is arranged to: its upper end-face edge 9U partly block as shown in Figure 5 on the second focus f3a that converges to aforementioned right elliptic reflecting surface 3a in the picture of the filament 2a of all directions with reverberation after left parabolic 4b contacts be last towards the picture of filament 2a, thereby light distribution characteristic is level along the H line.And, aforementioned right elliptic reflecting surface 3a, left parabolic 4a and shadow shield 9 (or shadow shield 9a) can be individually set on the optimum position in the present invention, so the light quantity that shadow shield 9 is blocked also can be set seldom.
And, in the lower right elliptic reflecting surface 5a of bottom concave mirror 5, be set at the position that is positioned at or below identical with light source 2, so when forming aforementioned bottom concave mirror 5, when forming lower right elliptic reflecting surface 5a (left side, bottom elliptic reflecting surface 5b), if major axis is changed to level, the last tendency that increases towards the ratio of light that comprises in the reverberation is arranged then.
Therefore, by for the lower right elliptic reflecting surface 5a that constitutes aforementioned bottom concave mirror 5 (left side, bottom elliptic reflecting surface 5b), be set at the second focus side that reduces major axis, or for the bottom object lens 6 that make up with lower right elliptic reflecting surface 5a (bottom a left side elliptic reflecting surface 5b), be set at produce down towards suitable modes such as reverberation, can freely select to reduce formation upward is used to increase effective light quantity towards the ratio of light mode etc.
And, make the second focus f7a2 (not shown) be positioned at the position extremely close with the upper end-face edge 9U of shadow shield 9 as the right elliptic reflecting surface 7a in the top of above-mentioned top concave mirror 7, be preferably the position that is no more than 1mm.Thus, the light distribution characteristic of the light of irradiation also as shown in Figure 5 by the left object lens 8b reflection corresponding with above-mentioned right elliptic reflecting surface 7a, covered a part by shadow shield 9, light distribution characteristic is level along the H line in the position of side on the lower side likening to horizontal H line in the present embodiment.In addition, the irradiates light that has passed through top concave mirror 7 is used for further increasing along the light component of the part of H line, and need not also can not make the second focus f7a2 (not shown) so near shadow shield 9 along under the situation of the tangent line of H line.
Shadow shield 9a is the same with shadow shield 9, be for partly block as shown in Figure 5 reverberation for last towards picture, the formation shape consistent of filament 2a with light distribution characteristic be provided with, and be set at the extremely close position of the second focus f5a2 of lower right elliptic reflecting surface 5a, be preferably and be no more than 1mm.The light that lower right elliptic reflecting surface 5a is reflected temporarily converges to after the second focus f5a2, arrives the left parabolic 6b of bottom object lens 6.Before arriving left parabolic 6b, its part is blocked by shadow shield 9a, in the present embodiment light distribution characteristic liken to for horizontal H line on the lower side the position of side along H line level.
In addition, shadow shield 9,9a are not only and are configured in the left side, are configured in the right side similarly.And principal goods mirror 4 and bottom object lens 6 form one on the right side, and aforementioned shadow shield 9,9a are fixed thereon.In the left side, principal goods mirror 4, bottom object lens 6 and aforementioned shadow shield 9,9a combine equally.
And bottom concave mirror 10 has bottom elliptic reflecting surface 10a, 10b in light source 2 sides, is configured in the downside of shadow shield 9a.And, on the object lens 6b of bottom, formed corresponding upper left of lower right elliptic reflecting surface 10a with the downside of the shadow shield 9a that is configured in the right side towards the facial 6ub of reflection, similarly, the upper right lower right elliptic reflecting surface 10a that towards reflection facial 6ua on bottom object lens 6a form corresponding with a left side, the bottom elliptic reflecting surface 10b of the downside setting of left side shadow shield 9b with first focus as light source.Second focus of lower right elliptic reflecting surface 10a and the upper left focus towards the facial 6ub of reflection of parabolic shape reflecting surface of forming are consistent or roughly consistent, make to be emitted to as shown in Figure 6 than the square on the upper side position of horizontal line H and near the luminous intensity distribution DU of vertical centre V by upper left the generation towards the facial irradiates light that is reflected of reflection.Similarly make by upper right the generation and also produce luminous intensity distribution DU towards the reflection irradiates light that facial 6ua reflected.Because luminous intensity distribution DU is suitable for the luminous intensity distribution specification of cart, so this illumination is to the maximum about 5 candelas (cd), thereby can not bring dizzy sense to opposite car.And Fig. 7 is the figure of the light distribution characteristic DU of expression lamps apparatus for vehicle 1 of the present invention.
And top concave mirror 7 specifically, is positioned near the rear and outer circumferential side of main concave mirror 3 for the light of catching the light source 2 that is in the position that aforementioned main concave mirror 3 and bottom concave mirror 5 can't capture is provided with.And, the part that above-mentioned main concave mirror 3 and bottom concave mirror 5 can't capture the light of light source 2 also can appear at the rear of bottom concave mirror 5, but in most cases be used for lamps apparatus for vehicle 1 is installed to mechanism on the car body, thereby interfere with its generating mechanism possibly this part being provided with.
And, promptly allow to capture, dispose aforementioned principal goods mirror 4 and bottom object lens 6 etc. in the place ahead of this part, be difficult to take out light, and again because of being positioned at the position more square on the lower side than light source 2, so reverberation also contain more go up towards composition, be difficult to effective utilization, to sum up, to increase effect limited by light quantity that speculum obtains is set in this part, therefore the downside at shadow shield 9a is provided with less bottom concave mirror 10, realizes the miniaturization of lamps apparatus for vehicle 1.
By forming lamps apparatus for vehicle 1 as mentioned above like that, in lamps apparatus for vehicle 1 of the present invention, with respect to the light summation that light source 2 produces, it is about 43% that the light quantity that can be used as illumination light reaches, and for existing searchlighting type light fixture, can obtain nearly 2 times efficient.
This structure installed at the car body center in the cart of a headlamp also and can throw light on the brightness of the carriage that is provided with 2 lamps, for example improved the visuognosis of opposite car etc. and improved security.And, be set at according to the present invention and utilize concave mirror and left and right sides object lens to send light two positions from a light source, therefore the visuognosis that has also improved opposite car from the light-emitting area increasing angles has also improved security thus.And the lamps apparatus for vehicle of this car brightens and has improved visuognosis for road surface etc., and can easily find barrier, thereby has improved security, and this is mathematical.
As mentioned above, according to the present invention, by by a plurality of be that the concave mirror of first focus and second focus direction expansion to the left and right encloses from previous packet with a light source 2, and on left and right directions, be provided with aforementioned second focus and be focus and be the parabolic of direction of illumination with the optical axis, first, by by main concave mirror 3,7 three in bottom concave mirror 5 and top concave mirror surround light source 2 and have improved the light catch rate, and be that the parabolic of focus is towards direction of illumination by utilizing second focus with the paraboloid of revolution that constitutes aforementioned each concave mirror, can realize comparing the bright lamps apparatus for vehicle 1 that has significantly improved the light catch rate of light source 2, obtain good effect aspect raising performance and the raising security with existing searchlighting type light fixture.
And, second, adopt structure of the present invention and significantly increased light-emitting area, and raising by above-mentioned light catch rate, light-emitting area deepening after having avoided enlarging, thereby the visuognosis of opposite car and the performance that Ben Che finds barrier have been improved, the security that helps to improve cart.
