Abstract
A kind of strip hot spot lens, comprise the plane of incidence, exit facet and reflecting surface, the described plane of incidence is positioned at the bottom of lens, described exit facet is positioned at the top of lens, described reflecting surface lays respectively at former and later two sides of lens, described reflecting surface is free form surface, upwards outward-dipping from bottom, and is also inclined upwardly to both sides from center line; Described exit facet is between two reflectings surface.The reflector design that the utility model is special, the reflecting surface of two sides is Random Curved Surface Designing, upwards outward-dipping from bottom, and be also inclined upwardly to both sides from center line, to make emergent ray be totally reflected in this face, and extensible beam, in vertical direction converging beam in the horizontal direction; The exit facet of upper end face is also Random Curved Surface Designing, adopts asymmetric design, is positioned at below horizontal line to make irradiation area; Make can get strip light spots by the light of this lens luminous intensity distribution, form "cut-off"line clearly for auxiliary sidelight lens.
Description
Technical field
The utility model relates to lens, especially can get the lens of strip hot spot, and for car light, auxiliary sidelight lens forms "cut-off"line.
Background technology
Existing car light general reflector luminous intensity distribution enables dipped beam LED get "cut-off"line, by the reflective design of reflector, although also can "cut-off"line be formed, but because reflector is good not to the aggregation extent of light, make the "cut-off"line formed only by reflector, its strip light spots is clear not, and that is the effect of "cut-off"line is obvious not.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of strip hot spot lens, and can form strip light spots, auxiliary sidelight lens forms "cut-off"line clearly.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of strip hot spot lens, comprise the plane of incidence, exit facet and reflecting surface, the described plane of incidence is positioned at the bottom of lens, described exit facet is positioned at the top of lens, and described reflecting surface lays respectively at former and later two sides of lens, and described reflecting surface is free form surface, upwards outward-dipping from bottom, and be also inclined upwardly to both sides from center line; Described exit facet is between two reflectings surface.The reflector design that the utility model is special, the reflecting surface of two sides is Random Curved Surface Designing, upwards outward-dipping from bottom, and be also inclined upwardly to both sides from center line, to make emergent ray be totally reflected in this face, and extensible beam, in vertical direction converging beam in the horizontal direction; The exit facet of upper end face is also Random Curved Surface Designing, adopts asymmetric design, is positioned at below horizontal line to make irradiation area; Make can get strip light spots by the light of this lens luminous intensity distribution, form "cut-off"line clearly for auxiliary sidelight lens.
As improvement, the centre position, bottom of described lens is bright dipping region, and the both sides of bottom are FX, and described FX is provided with locating dowel and installing hole.
As improvement, described exit facet takes the shape of the letter U, and extend downward the bottom of lens, and the width of exit facet reduces gradually from two both sides about the top of lens toward bottom from top.
The beneficial effect that the utility model is compared with prior art brought is:
The reflector design that the utility model is special, the reflecting surface of two sides is Random Curved Surface Designing, upwards outward-dipping from bottom, and be also inclined upwardly to both sides from center line, to make emergent ray be totally reflected in this face, and extensible beam, in vertical direction converging beam in the horizontal direction; The exit facet of upper end face is also Random Curved Surface Designing, adopts asymmetric design, is positioned at below horizontal line to make irradiation area; Make can get strip light spots by the light of this lens luminous intensity distribution, form "cut-off"line clearly for auxiliary sidelight lens.

Fig. 2 is the utility model stereogram II.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in further detail.
As shown in Figure 1, 2, a kind of strip hot spot lens, comprise the plane of incidence 1, exit facet 2 and reflecting surface 3.The described plane of incidence 1 is positioned at the bottom of lens, and the centre position, bottom of described lens is bright dipping region 11, and the both sides of bottom are FX 12, and described FX 12 is provided with locating dowel 4 and installing hole 5, for being fixed by lens.Described exit facet 2 is positioned at the top of lens, and described exit facet 2 takes the shape of the letter U, and extend downward the bottom of lens, and the width of exit facet 2 reduces gradually from two both sides about the top of lens toward bottom from top.Described reflecting surface 3 lays respectively at former and later two sides of lens, and described reflecting surface 3 is free form surface, upwards outward-dipping from bottom, and is also inclined upwardly to both sides from center line.Described exit facet 2 is between two reflectings surface 3.The special reflecting surface 3 of the utility model designs, the reflecting surface 3 of two sides is Random Curved Surface Designing, upwards outward-dipping from bottom, and be also inclined upwardly to both sides from center line, be totally reflected in this face to make emergent ray, and extensible beam in the horizontal direction, in vertical direction converging beam; The exit facet 2 of upper end face is also Random Curved Surface Designing, adopts asymmetric design, is positioned at below horizontal line to make irradiation area; Make can get strip light spots by the light of this lens luminous intensity distribution, form "cut-off"line clearly for auxiliary sidelight lens.
