Abstract
The utility model provides a lens structure for vehicle headlamps comprises light transmissive portion (1) and installation parts (2), and lens, its characterized in that are regarded as with aspherical lens in light transmissive portion (1): the surface of light transmissive portion (1) be divided into main lens district (3) and assist lens districts (4), main lens district (3) with assist lens districts (4) and have not co -altitude, assist lens districts (4) and establish below (3) are distinguished to the main lens than the facial height in subsidiarys lens districts (4) in main lens district (3). The utility model discloses, through the combination in main lens district and assistance lens district, can satisfy the requirement to distance light light shape's regulation and each grading test point illuminance of ECE or GB standard when realizing far and near smooth switching to being equipped with the sparrow pecked in the lens district and making distance light illuminance value more even with assisting through main lens district, it is dark excessively to prevent to cross bright border in the middle of the light, has improved the security of driving a vehicle greatly.
Description
Technical field
The utility model relates to a kind of automobile front lighting technical field, is specifically related to a kind of car headlamp lens arrangement.
Background technology
Headlamp is that automobile throws light on when night running the light fixture of road ahead, and its luminous intensity distribution design is the key factor affecting lighting quality and effect.Projection optical unit is applied more and more universal on car headlamp, this is because projection optical unit bring high-grade sense can not only to whole headlamp and it has high light-gathering, good horizontal development width, also more attractive in appearance.Projection optics list forms primarily of light source, speculum, shadow shield and convex lens, and the projection optical unit of existing distance-light one adds electromagnetic valve structure, for realizing the switching of distance-light on shadow shield.According to the difference of automobile type configuration, the projection optical unit of Different Light can be selected, but no matter be adopt which kind of configuration, all must meet the numerical requirements to the regulation of distance-light shape and each luminous intensity distribution test point in ECE or GB standard.Current dipped headlights 5.7.4.3 item in automobile lamp regulation GB4599-2007 requires regulation: test point P1+P2+P3≤0.3lx, P4+P5+P6≤0.6lx, 0.7lx≤P7≤0.1lx, 0.7lx≤P8≤0.2lx.This dipped beam, owing to using shadow shield as the effect of blocking, level is all covered by line and 15 degree of light above line, and its luminous energy is almost nil, therefore can not meet 5.7.4.3 item requirement in above-mentioned GB4599-2007.
Summary of the invention
For above shortcoming, the utility model object is to provide a kind of car headlamp lens arrangement, the main lens district of differing heights and auxiliary lens district on scioptics, speculum is arrived the light of lens surface, respectively by main lens district and the scattering of auxiliary lens district and refraction, project each test point of automobile dimming-distance light luminous intensity distribution testing standard regulation, formed and meet the distance-light light shape that standard specifies illumination requirement.
The technical scheme of the utility model technology is achieved in the following ways: a kind of car headlamp lens arrangement, be made up of light transmission part and mounting portion, light transmission part is using non-spherical lens as lens, it is characterized in that: the surface of described light transmission part is divided into main lens district and auxiliary lens district, there is differing heights in main lens district and auxiliary lens district, main lens district is higher than the face in auxiliary lens district, and auxiliary lens district is located at below main lens district.
Described main lens district is larger than auxiliary lens district, and auxiliary lens district is located at immediately below main lens district, the vertical point of B50L test point to auxiliary lens district and the distance of lens Y-axis in 25 meters/10 meters test screen that the setting of auxiliary lens district left and right width can not be less than standard regulation.
Described main lens district is placed on the primary optical axis of projection optical unit.
Described mounting portion is provided with positioning port.
Described main lens district and auxiliary lens district are placed with well word decorative pattern or sparrow pecked.
The utility model structure, by the combination in main lens district and auxiliary lens district, while can switching realizing distance-light, meet the requirement of ECE or GB standard to the regulation of distance-light light shape and each luminous intensity distribution test point illumination, and be provided with sparrow pecked by main lens district and auxiliary lens district and make distance light brightness value more even, prevent in the middle of light, crossing bright border excessively dark, substantially increase the security of driving.
Accompanying drawing explanation
Fig. 1 is the structural representation of the new shape of this practicality.
Fig. 2 is the front view of Fig. 1.
Fig. 3 is the left view of Fig. 2.
In figure: 1 light transmission part, 2 mounting portions, 3 main lens districts, 4 auxiliary lens districts, 5 positioning ports, 6 sparrow peckeds.
Detailed description of the invention
By Fig. 1, Fig. 2, Fig. 3 knows, a kind of car headlamp lens arrangement, be made up of light transmission part 1 and mounting portion 2, light transmission part 1 is using non-spherical lens as lens, the surface of described light transmission part 1 is divided into main lens district 3 and auxiliary lens district 4, there is differing heights in main lens district 3 and auxiliary lens district 4, main lens district 3 is higher than the face in auxiliary lens district 4, main lens district 3 is larger than auxiliary lens district 4, auxiliary lens district 4 is located at immediately below main lens district 3, the setting of auxiliary lens district about 4 width can not be less than the vertical point of 25 meters/10 meters test screen B50L test points to auxiliary lens district 4 and the distance of lens Y-axis of standard regulation, if be less than this distance, the state that B50L point does not work easily is there is in dipped beam when luminous intensity distribution, only have when being greater than this apart from the brightness value that just can not have influence on B50L, main lens district 3 is placed on the primary optical axis of projection optical unit, when lens install rear reflector by light reflection to lens, main lens district 3 mainly forms dipped beam light shape, meet the regulation brightness value requirement of dead line lower zone, some light is by behind auxiliary lens district 4, a series of scattering and refraction can be produced, the top of final arrival dead line, meet dipped beam luminous intensity distribution area light shape, realize the requirement of test point P1+P2+P3≤0.3lx, P4+P5+P6≤0.6lx, 0.7lx≤P7≤0.1lx, 0.7lx≤P8≤0.2lx, mounting portion 2 is provided with positioning port 5, is positioned by positioning port 5 when lens are installed, and can rotate, affect supplementing III district's light after preventing lens from installing.Main lens district 3 and auxiliary lens district 4 are placed with well word decorative pattern or sparrow pecked 6, be provided with word decorative pattern or sparrow pecked 6 makes distance light brightness value more even, prevent in the middle of light, crossing bright border excessively dark, prevent distant light irradiation scope from crossing window, substantially increase the security of driving.
