Abstract
A kind of car headlamp lens, including lens, described lens include incidence surface（1）With exiting surface（2）；It is characterized in that：Described exiting surface（2）The arcwall face of sphere or aspheric surface convex lenss for lens outer surface, exiting surface（2）One or more boss in uniform arrangement are provided with its lateral shaft or near which（3）.This utility model, the light that light source sends enter lens by the incidence surface of lens, carry out the refraction of light, send light by exiting surface afterwards, and carry out the supplement of light by the boss on exiting surface to 8, IIIth area test point.
Description
Technical field
This utility model is related to a kind of automobile front lighting technical field, and in particular to a kind of car headlamp lens.
Background technology
Headlamp is the light fixture that automobile illuminates road ahead in night running, and its luminous intensity distribution design is to affect lighting quality
With the key factor of effect.Projection optical unit is applied on car headlamp and is increasingly popularized, this is because projection optics list
Unit can not only bring high-grade sense to whole headlamp and it has high light-gathering, good horizontal development width, also more attractive.Throw
Optics list is penetrated mainly by light source, reflecting mirror, dark slide and convex lens group into the projection optical unit of existing distance-light one exists
Electromagnetic valve structure is increased in dark slide, for realizing the switching of distance-light.According to the difference of automobile type configuration, difference can be selected
The projection optical unit of light source, but whether being using which kind of configuration, it is necessary to meet in ECE or GB standards to distance-light shape
The numerical requirements of regulation and each luminous intensity distribution test point.Current dipped headlights 5.7.4.3 in automobile lamp regulation GB4599-2007
Item 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, due to using dark slide as the effect of blocking, light of the level by line and 15 degree above line
All it is occluded, its luminous energy is almost nil, therefore can not meet 5.7.4.3 item requirements in above-mentioned GB4599-2007.
Existing lens are mainly traditional circle at present, cannot meet the various shapes needs of automobile lamp.
The content of the invention
For disadvantage mentioned above, this utility model purpose is to provide a kind of car headlamp lens, and the light that light source sends leads to
The incidence surface for crossing lens enters lens, carries out the refraction of light, sends light by exiting surface afterwards, and by exiting surface
Boss carries out the supplement of light to 8, IIIth area test point.
The technical scheme of this utility model technology is achieved in the following ways：A kind of car headlamp lens, including
Lens, described lens include incidence surface and exiting surface；It is characterized in that：Described exiting surface for lens outer surface sphere or
The arcwall face of aspheric surface convex lenss, exiting surface are provided with one or more on its lateral shaft or near which in uniform arrangement
Boss.
Described lens are square structure.
Upper and lower two side elevation of described lens is provided with the installation wing of one, and is provided with positioning in lens arranged on left and right sides
Groove.
Under described lens, side elevation is provided with ribs.
This utility model structure, the light that light source sends enter lens by the incidence surface of lens, are reflected, and pass through afterwards
Light is sent by bright finish, and the supplement of light is carried out to 8, IIIth area test point by the boss on exiting surface, GB4599- is met
In 2007,5.7.4.3 items are required；Lens design squarely structure is increased new creation to Design of Luminaires in addition to select.
Description of the drawings
Fig. 1 is the three-dimensional structure diagram of the new shape of this practicality.
Fig. 2 is the front view of Fig. 1.
Fig. 3 is the rearview of Fig. 1.
In figure：Wing, 5 locating slots, 6 ribs are installed in 1 incidence surface, 2 exiting surfaces, 3 boss, 4.
Specific embodiment
Known by Fig. 1, Fig. 2, Fig. 3, a kind of car headlamp lens, including lens, described lens include incidence surface 1 and go out
Bright finish 2；Arcwall face of the described exiting surface 2 for the sphere or aspheric surface convex lenss of lens outer surface, exiting surface 2 is in its lateral shaft
Lower section be provided with six boss 3 in laterally homogeneous arrangement；The light that light source sends enters lens by the incidence surface 1 of lens, enters
Light is sent by exiting surface 2, carries out light by 3 pairs of 8, the IIIth area test points of boss on exiting surface 2 by row refraction afterwards
Supplement, meet dipped beam luminous intensity distribution area light shape, realize test point P1+P2+P3≤0.3lx, P4+P5+P6≤0.6lx, 0.7lx≤
The requirement of P7≤0.1lx, 0.7lx≤P8≤0.2lx；Described lens are square structure, and lens design squarely structure is given
Design of Luminaires increases new creation and selects.Upper and lower two side elevation of described lens is provided with the installation wing 4 of one, and saturating
Mirror arranged on left and right sides is provided with locating slot 5, and lens are positioned by locating slot 5 when installing, fixed saturating by the installation wing 4 of both sides afterwards
It is on mirror support, quick and easy for installation；Lens are unnecessary in order to prevent from running out of at side elevation under lens after being arranged on lens carrier
Light affects light type effect, and side elevation is provided with ribs 6 under a lens, breaks up unnecessary light by ribs 6, carries
Highlight type effect.When this lens is used in road function simultaneously, boss 3 thereon will be distance light brightness value more uniform, prevents light
Middle excessively bright border is excessively dark, substantially increases the safety of driving.
