Technical field
The utility model relates to car light, is especially applied in the headlamp on automobile or motorcycle.
Background technology
Existing car light generally comprises low beam light source and high-beam light source, and in order to meet the requirement of car light, low beam light source must can get "cut-off"line.Existing low beam light source utilizes reflector luminous intensity distribution to enable 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 headlamp, can get the "cut-off"line of cleaning.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of headlamp, comprise drain pan, cover, low beam light source assembly and high-beam light source assembly, also comprise secondary light source assembly, the attachment lens that described secondary light source assembly comprises auxiliary LED and coordinates with described auxiliary LED, described attachment lens comprises the plane of incidence, exit facet and reflecting surface, the described plane of incidence is positioned at the bottom of attachment lens, described exit facet is positioned at the top of attachment lens, described reflecting surface lays respectively at former and later two sides of attachment lens, 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 utility model utilizes low beam light source assembly and secondary light source assembly jointly to form "cut-off"line clearly.Attachment lens adopts special reflector design, 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, 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 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, described low beam light source assembly and high-beam light source assembly are setting up and down, and secondary light source components distribution is in the both sides in low beam light source assembly and high-beam light source assembly centre position.
As improvement, the centre position, bottom of described attachment 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, the exit facet of described attachment lens takes the shape of the letter U, and extend downward the bottom of attachment lens, and the width of the exit facet of attachment lens reduces gradually from two both sides about the top of attachment lens toward bottom from top.
As improvement, described low beam light source assembly comprises dipped beam LED and sidelight lens, and described high-beam light source assembly comprises distance light LED and distance light lens; Be provided with mount pad in described drain pan, described sidelight lens and distance light lens are fixed on described mount pad.
As improvement, described mount pad comprises the first groove for installing sidelight lens, for installing the second groove of distance light lens and being located at the bolt column of mount pad periphery.
The beneficial effect that the utility model is compared with prior art brought is:
The utility model utilizes low beam light source assembly and secondary light source assembly jointly to form "cut-off"line clearly; Attachment lens adopts special reflector design, 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, 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 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.
