Abstract
The utility model discloses a kind of devices that Rear Position Lamp uniformly light-emitting is realized by interior lens, including LED luminescence unit, the LED light that the LED luminescence unit is evenly arranged by one group forms, it further include lens in lens and second in first, lens is relative to lens in second closer to outer lens in described first, and lens is located in described first between lens and LED light in described second；The inner surface of lens is equipped with Fresnel patterned surface corresponding with LED light in described second.
Description
Technical field
The utility model relates to car light technical fields, in particular to a kind of to realize that Rear Position Lamp is uniformly sent out by interior lens
The apparatus structure of light.
Background technique
With the development of Automobile Market, consumer is higher and higher for the cosmetic requirements of civil car, correspondingly,
Utilization of the LED on automobile signal light is also more universal, and apt word added to clinch the point of the Rear Position Lamp as vehicle modeling, also towards moulding
Diversification, personalized direction are developed, and the requirement for its lighting uniformity is also very harsh.
Currently, in the case where OLED can not be popularized because of technology and cost problem, after being realized in scattering material with+LED
The scheme of position lamp is used by major vehicle factor.
It is as shown in Figure 1 one of scheme commonly used in the prior art, whole device is by outer the lens 1, (scattering of interior lens
PC) 2, the main components such as LED unit 3, pcb board 4, lamp body 5, reflecting mirror 6 and decorative circle 7 composition；The program has following defects that
Referring to shown in Fig. 2, since LED light diffusion angle is fixed, and light intensity is in from the LED centre of luminescence to surrounding
Decline trend.In the case where LED is certain at a distance from interior lens 2, for the uniformity of luminance for guaranteeing position lamp, LED unit 3
In the spacing of adjacent LED cannot be too big, thus cause the quantity of LED to increase, whole lamp cost increase.
Also, the program is stringent for the required distance of LED and interior lens 2, generally requires this distance in 25mm or more,
Once this will generate speck because light is concentrated apart from too small on interior lens 2, and then influence lighting uniformity；It is another
Aspect, vehicle body sheet metal press depth often will limit the distance, increase design difficulty.
Utility model content
There is good lighting uniformity the technical problem to be solved by the utility model is to provide one kind and convenient for real
The existing device that Rear Position Lamp uniformly light-emitting is realized by interior lens.
Its technical problem to be solved can be implemented by the following technical programs.
A kind of device for realizing Rear Position Lamp uniformly light-emitting by interior lens, including LED luminescence unit, the LED hair
The LED light that light unit is evenly arranged by one group forms, feature be further include lens, institute in lens and second in first
Lens is stated in first relative to lens in second closer to outer lens, lens is located in described first in described second
Between lens and LED light；The inner surface of lens is equipped with Fresnel patterned surface corresponding with LED light in described second.
As the further improvement of the technical program, lens is in concave-convex alternate section structure in described second, relatively
A LED lamp is corresponded in the inside of the LED light, each protrusion part.
As the further improvement of the technical program, some or all of the inner surface of the protrusion part is the phenanthrene
Nie Er patterned surface.
As the preferred embodiment of the utility model, the LED light one shares 11.
The device that Rear Position Lamp uniformly light-emitting is realized by interior lens by adopting the above technical scheme, realizes the benefit of light
With maximization, design difficulty is reduced；Lighting effect is more preferable.LED quantity can be effectively reduced simultaneously, there is positive reality meaning
Justice.
Detailed description of the invention
Fig. 1 is existing position lamp structural schematic diagram；
Fig. 2 is LED radiation performance plot；
Fig. 3 is the structural schematic diagram and its partial enlargement diagram of utility model device；
Fig. 4 is the decomposition texture schematic diagram of utility model device；
Specific embodiment
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing.
For drawbacks described above existing for Rear Position Lamp in the prior art, the utility model provides a kind of by matching in two
The device of light microscopic realization Rear Position Lamp uniformly light-emitting.
Referring to shown in Fig. 3 and Fig. 4, refraction principle of the device according to light, the excessively interior lens B (figure label 8) of utilization
Fresnel decorative pattern 81 light that LED unit 3 issues is gathered after spread out according still further to specific direction, be uniformly irradiated to
On interior lens A (figure label 12), to realize that utilizing for light maximizes, is reached with this and reduce LED quantity, reduced structure and set
Count the purpose of difficulty.
Specific structure is, inside lamp body 5, is equipped with pcb board 4, is laid with LED unit 3 on pcb board 4, LED unit 3 is by 11
The LED light 31 that is evenly arranged of interval forms, the interior lens A (figure label 12) that LED light 31 and scattering PC are constituted it
Between be also provided with an interior lens B, the interior lens B shape is in concave-convex alternate section structure (such as waveform or water channel
Type), relative to LED light, each inside configuration for being convex to interior lens A corresponds to a LED lamp 31, also, the protrusion knot
Some or all of inner concave of structure is Fresnel patterned surface (referring to the Fresnel decorative pattern 81 in figure).
The upper left corner is the amplification signal of circled in figure in Fig. 3, and which show the form knots of specific Fresnel decorative pattern 81
Structure.
Compared with existing scheme illustrated in Figure 1, the advantages of present apparatus, is embodied at following 2 points:
1, increase the spacing of adjacent LED, reduce in unit area LED quantity (by taking the present embodiment as an example, LED number
Amount reduces 5), it reduces costs, improves cost competitiveness；
2, by the refraction of interior lens B, the light intensity distributions that LED is issued are uniform, therefore can reduce LED and interior light distribution
The distance of mirror A, reduces design difficulty.
