Light compensating lamp 1 includes lamp housing 11, light source 12 and lens array part 13 as described in Fig. 1-3, and wherein lamp housing 11 is cavity type
Structure, the lamp housing 11 have light-emitting window 111, and the light source 12 and the lens array part 13 are fixed in lamp housing 11, described
The lens array part 13 that the light directive of light source 12 is fixed in the lamp housing 11 is sent from the light-emitting window 111, the lens arrays
Battle array part 13 includes the sidelight lens 131 and distance light lens 132 for alternating setting, in order to improve the anti-dazzle light effect of light compensating lamp 1,
Go out one glare filter 14 of increase in light-emitting window 111.
All sidelight lens 131 and distance light lens 132 all have respective optical axis, and their optical axis is due to sidelight lens
131 with distance light lens 132 alternate setting and so that optical axis is parallel array is spaced apart.
Wherein, the light source 12 can use LED luminescent screens, and LED luminescent screens are fixed on the position of the inner terminal of lamp housing 11, institute
State LED luminescent screens be provided with respectively with each sidelight lens 131 and each 132 corresponding LED module of the distance light lens
121, LED module 121 can use light emitting diode, that is to say, that the quantity of LED module 121 is and sidelight lens 131 and distance light
The total number of lens 132 is consistent, the corresponding sidelight lens 131 of LED module 121 or a distance light lens
132, sent again in lens corresponding to the light injection that LED module 121 is sent, wherein above-mentioned sidelight lens 131 can use dipped beam
TIR lens, the distance light lens 132 can use distance light TIR lens, and TIR lens are that Total Internal Reflection are saturating
Mirror.
Dipped beam TIR lens and distance light TIR lens can use optical plastic lens to make, and its material used can be poly- first
The refined e pioic acid methyl ester of base（PMMA）It can also be makrolon（PC）, the universal advantage of optical plastic lens is that optics utilization rate is high,
Material is cheap.
For convenience in the fixation of lens, the stability of printing opacity is improved, is located at each LED mould on the LED luminescent screens
The first hollow circular-tube 15 is fixed with group 121, and during installation, each sidelight lens 131 and each distance light lens 132 divide
Do not fixed by first hollow circular-tube 15.
Further, glare filter 14 is made using the light transmissive material of resin material or resin material, glare filter 14
Concrete structure can be as follows, glare filter 14 extend internally have respectively with each sidelight lens 131 and each distance light
Multiple second hollow circular-tubes 141 corresponding to lens 132, the light projected from the sidelight lens 131 and the distance light lens 141 enter
Enter in the second hollow circular-tube 141, then sent from the second hollow circular-tube 141, the second hollow circular-tube 141 have absorb and block by
The function for the part remaining light that TIR lens are sent, make there was only key light injection substantially.
The concrete structure of second hollow circular-tube 141 again can be further to be tubaeform, and second hollow circular-tube 141 is close
One end of the light-emitting window 111 is small-caliber end, and key light projects from flared structure, is camera light filling, and such a design is maximum
Limit reduces the remaining light seen by passerby and driver, and the remaining light for eliminating conventional light compensating lamp is asked pedestrian and the dazzling of vehicle
Topic, the anti-dazzle light effect of such a structure, substantially completely better than conventional anti-glare light compensating lamp.
On the structure of lens, as Figure 4-Figure 6, specifically, the sidelight lens 131 and the bottom of distance light lens 132
Portion has thang-kng cavity 10, the bottom and top of the plane of incidence 20, herein meaning that are protruded in the thang-kng cavity 10 for top respectively
Portion, when being stood up with light transparent lens for, i.e., exiting surface is towards for surface, and the plane of incidence 20 makees smooth treatment, described
There are multiple inclined-planes 40 be arrangeding in parallel on the exiting surface 30 of sidelight lens 131, the section on inclined-plane 40 is similar to right angle prism,
The part evagination of exiting surface 30 of the distance light lens 132 formed with free form surface 50, the inclined-plane 40 extend laterally direction with
The free form surface 50 extends laterally that direction is identical, and transverse direction referred herein is X-direction, the plane of incidence of the top protrusion
For parabola or ellipsoid, the free form surface is evagination hemisphere face, and the hemispherical section of evagination is similar to half convex lens, institute
The both sides for stating outer convex spherical are plane.
Dipped beam TIR lens or distance light TIR lens when mounted, are typically horizontally arranged at lamp by the utility model with respect to ground
Shell, inclined-plane extend laterally direction and free form surface extend laterally direction（X-direction）It is parallel to the ground, and when putting
An angle α can be formed with ground（Y-axis and ground angle）, generally 1 10 ° of ＜ α ＜.
LED module on LED luminescent screens is placed in the thang-kng cavity of dipped beam TIR lens or distance light TIR lens, LED moulds
A part of light that group is sent reflects by thang-kng cavity, and refraction light reflects by the fully reflecting surface of TIR lens and forms standard
Direct light line, another light that LED module is sent can be by another part light that light source is sent by the plane of incidence in thang-kng cavity
Line collimates.
For distance light TIR lens, when most of light beam passes through the parallel-slope on the exiting surface of TIR lens, light
Substantially do not reflect, and form less elliptical spot a long way off（The more hot spot of light is smaller so this hot spot brightness is high）
When fraction light beam passes through the free form surface of exiting surface, light beam is based on refraction principle, anti-raw refraction, and is formed on hand less
Elliptical spot（Light is less so brightness is low）, for dipped beam TIR lens, segment beam can pass through the plane of exiting surface
And form less elliptical spot a long way off, some light can by top convex spherical and reflect, formed on hand
The uniform excessive hot spot of Long Circle.
Embodiment of the present utility model simply introduces its embodiment, does not lie in and limits its protection domain.The industry
Technical staff can make some modifications under the inspiration of the present embodiment, therefore all done according to the utility model patent scope
Equivalent change or modification, it is not limited to illustrate profile, belongs in the utility model patent right.
