Specifically can realize by following form:
First scheme-this incidence surface comprises at least two quadratic surfaces, and described curved surface is arranged side by side, and the curvature of described curved surface is along the orientation monotone variation of described curved surface; This exiting surface is a free form surface, and it has a line of demarcation this free form surface is divided into big or small both sides, and the curvature of the bigger N-Side surf of area changes to be delayed in the less N-Side surf of area; Make the curved sides deflection of light with this through described lens area maximum on the curved sides of curvature minimum on this incidence surface and this exiting surface;
The central shaft (being equivalent to Z axle in the following examples) that should as far as possible guarantee described incidence surface when wherein, described lens cover light source passes described light source position (being equivalent to O point in the following examples); Described line of demarcation, be one to be parallel to quadric orientation on the incidence surface (orientation promptly is equivalent to X-direction in the following embodiments, when being a plurality of quadratic surface, it is arranged also to extending arranging on the X-direction) and comprise the projection of plane on described exiting surface of the central shaft of incidence surface; Can be when lens are one-body molded according to the deviation direction of desired emergent ray, make that there is a corresponding angle in quadric orientation on the projection (promptly being equivalent to Y direction in the following examples) of trend direction on horizontal plane that the curvature of free form surface on the exiting surface changes and the incidence surface.
Alternative plan-this exiting surface is a free form surface, and it has a line of demarcation this free form surface is divided into big or small both sides, and the curvature of the bigger N-Side surf of area changes to be delayed in the less N-Side surf of area; This incidence surface comprises at least one shape free form surface of exiting surface as described, as be a plurality of as described in free form surface, described free form surface is arranged side by side, the trend unanimity that changes along the curvature of each free form surface of orientation of described free form surface (be each free form surface in orientation all be same direction side curved surface area greatly and curvature change gently, the less and curvature of the area of the curved surface of other direction side changes hurriedly); Make light change the curved sides deflection of area maximum on a mild side and this exiting surface to the curvature of each free curved surface on this incidence surface through described lens with this;

Because above-mentioned two kinds of main implementation principles are identical, therefore only comprise that with indent light inlet face in first scheme two quadratic surfaces are that example is described below, other implementations contain the structure of a plurality of quadratic surfaces or at least one free form surface as indent light inlet bread, just give unnecessary details no longer one by one.
In addition, above-mentioned angle is provided with as required, in the embodiment of this programme, for convenience, only be an angle of 90 degrees with X-axis and Y-axis and be described, but this programme is not limited to this.
The luminescence component of the utility model design as shown in Figure 2, comprises a light emitting diode 10, one and the lens 20 of light emitting diode 10 collocation and the reflector 30 that places the side of these lens 20.The light-emitting diode structure shape does not limit.Lens leave screens, and reflector is placed in the described screens, perhaps reflector is fixed on aluminium base or the radiator with screw with lens.
Below with an embodiment lens are described.
These lens are one-body molded by the transparent material of superb optical performance, as PMMA or PC plastics.Reflector is one-body molded by white PC or ABS etc.For making things convenient for subsequent descriptions, introduce a three-dimensional rectangular coordinate system herein, as illustrated in fig. 1 and 2, wherein X-axis is corresponding to the width (being left and right directions) of lens 20, Y-axis is corresponding to the length direction (being fore-and-aft direction) of lens 20, the Z axle is corresponding to the short transverse (being above-below direction) of lens 20, and simultaneously, the Z axle also is the optical axis of light emitting diode 10.Optical axis (Z axle) with light emitting diode 10 is a benchmark, and lens 20 cover on the light emitting diode 10 and the central shaft of the indent incidence surface of lens 20 overlaps with optical axis of LED, promptly makes the central shaft of indent incidence surface of lens 20 also be the Z axle.Can change peripheral structure except that lens incidence surface and exiting surface so that fixed reflector.
Fig. 3 is the view of not ipsilateral of this secondary lens 20 of corresponding diagram 1, with reference to Fig. 3 c, wherein 1 is exiting surface, but this exiting surface 1 and be a monoblock sphere curved surface unlike traditional lens exiting surface, neither form by the smooth connection of polylith curved surface, this curved surface fits to curve (being commonly referred to as bus) by a plurality of discrete points and converts curved surface again to, and in fact it is a free form surface.With reference to Fig. 3 a, 3b and 3c, this exiting surface 1 is about the Y-axis symmetry.With the initial point is the center, choosing the plane of X-axis and Z axle formation and the intersecting lens of exiting surface 1 is the line of demarcation, this exiting surface is divided into big or small two parts by described line of demarcation, the positive direction surface area of Y-axis is big and the curvature variation is comparatively slow, the surface area of Y-axis negative direction is less and the curvature variation is very fast, the purpose of doing like this is to allow light be partial to the positive axis of Y-axis, i.e. directive direction of traffic (referring to Figure 10) as far as possible.
Shown in Fig. 4 b, the cross section of Y direction, after the light of unspecified angle incided the incidence surface of lens, the angle of light that enters lens was less than incident ray, and promptly this incidence surface plays the effect of dispersing slightly towards the positive direction side of Y-axis to light.
For exiting surface, when light marches to exiting surface because light is to be passed to air by medium, thereby the angle of emergence is greater than incidence angle (this incidence angle is the angle of emergence of incidence surface), the area that the curvature that is positioned at central shaft left side (Y-axis positive direction side) changes curved surface slowly greatly, so most light all are to change curved surface refraction slowly through curvature to change to the positive direction lateral deviation of Y-axis, and disperse slightly.
Note, guarantee that the central shaft (chain-dotted line) of indent incidence surface overlaps with optical axis of LED (chain-dotted line).
Incidence surface is to be formed by connecting along the directional smoothing of X-axis by different quadratic surface 2a, the 2b of two amount of curvature among Fig. 3, with reference to Fig. 3 d and 3e, this incidence surface is about the X-axis symmetry, the curved surface 2b curvature that is in the X-axis positive direction is less than the curved surface 2a that is in the X-axis negative direction, the purpose of doing like this is to allow light be partial to the negative semiaxis of X-axis as far as possible, be light downward bias, directive road surface (referring to Figure 10).
Shown in Fig. 4 a, the cross section of directions X, when the light of unspecified angle incided the incidence surface of lens, because light is to be passed to medium by air, the angle of emergence was less than incidence angle.On the incidence surface, the less curved surface of curvature is positioned at X-axis positive direction side, have on the quadratic surface more most curved surface (part of irising out among Fig. 4 a) on it arbitrarily the normal direction of any point to upper left side (X-axis positive direction side), thereby most light will be to the negative direction lateral deviation folding of X-axis.
For exiting surface, because light is to be passed to air by medium, the angle of emergence is greater than incidence angle (this incidence angle is the angle of emergence of incidence surface), this moment, the more multidirectional X-axis negative direction of the most emergent raies lateral deviation in central shaft left side was changeed, the more multidirectional X-axis positive direction of the most emergent raies lateral deviation on central shaft right side is changeed, and the emergent ray deflection on central shaft right side is more than the emergent ray in central shaft left side; Generally, the emergent ray through lens is played the effect of gathering slightly to central shaft.
Because this light fixture ring roads that are applied to more, and ring road is had a lot of social connections generally at 7-14 rice, so light fixture generally is in the height of 0.5-0.75 rice when mounted, thereby the design of lens should make the deflection angle of emergent ray should be not excessive according to demand, otherwise possibly can't shine whole ring road road surface.
Based on above characteristics, described lens are integrated the light that is sent by light emitting diode by the mode of refraction, total reflection, redistribute the light path of emergent ray.Make most light follow the outgoing of car direction, simultaneously, must deflect down, be beneficial to more light is projected road surface (referring to Figure 10) at vertical road direction light.
When mounted, said lens places on the aluminium base rule to arrange, and lens can be rotated suitable angle according to actual needs, and general lens in the horizontal direction and aluminium base have the angle a of a 5-10 degree, as shown in Figure 5, this angle is regulated according to the mounting distance of light fixture.
Below with another embodiment reflector is described.
As shown in Figure 6, described reflector places on the lens and is positioned at curved surface one side of the Y-axis negative direction side of described lens exiting surface, and the screens of reflector and the draw-in groove of lens closely cooperate and make things convenient for the product assembling.
In order to reduce dazzle and light pollution, the inner surface of reflector (reflecting surface) is quadratic surface or free form surface, the electrodepositable highly reflective material to be obtaining minute surface reflecting effect or diffuse effect, if use the higher white plastic of reflectivity then its inner surface can not deal with.Its effect be will negative Y direction (the less curved surface of lens exiting surface) light reflex to positive Y direction, this part light will follow the outgoing of car direction, not only reduce the utilization ratio that dazzle has also greatly improved luminous energy, with reference to figure 7.
At the arrangement mode of a plurality of luminescence components of Fig. 5, this outer surface may cause reflection to the light of the luminescence component outgoing that is arranged in its back, thereby causes unfavorable factors such as dazzle.In order to reduce or this kind unfavorable factor that weakens, the outer surface of described reflector must be done processing such as erosion line or frosted breaing up the light that shines this outer surface from a back luminescence component, but this outer surface there is no fixed profile.Certainly, if the luminescence component spacing of light fixture enough greatly also can not done the erosion line or frosted is handled.
Described luminescence component uses in the ordinary course of things in pairs, promptly is divided into being installed in road left side and right side.With reference to shown in Figure 8, relative two kinds of luminescence components (shape of incidence surface is relative) except that the incidence surface difference of lens of installing, remainder is all identical, assembles also identical with fixed form.
Assembling can also be made amendment to lens body for convenience, and as shown in Figure 9, this structure only needs lens card on aluminium base, and is easy to operate, improves packaging efficiency greatly.
In order to adapt to the requirement of different ring roads, this luminescence component is applied in the actual light fixture, generally all arranges by the certain spacing rule, but does not limit the number that this luminescence component uses.
In addition, referring to Figure 10 a, along the vertical view of road direction, along the direction of traffic irradiation, the distance of irradiation is near the spacing of two lamps as far as possible for the light of light fixture outgoing; And importantly can avoid light oppositely to penetrate,, produce unfavorable factors such as dazzle in case shine driver's eyes; In addition, referring to Figure 10 b, at vertical road direction, the light of light fixture outgoing can photograph as much as possible to the road surface, the distance of this direction irradiation is near the width of road.
Above-mentioned explanation illustrates and has described some preferred embodiments of the present utility model, but as previously mentioned, be to be understood that the utility model is not limited to the disclosed form of this paper, should not regard eliminating as to other embodiment, and can be used for various other combinations, modification and environment, and can in utility model contemplated scope described herein, change by the technology or the knowledge of above-mentioned instruction or association area.And change that those skilled in the art carried out and variation do not break away from spirit and scope of the present utility model, then all should be in the protection domain of the utility model claims.
