Abstract
A kind of structure preventing lens speck in car light, it is related to functional character or the parts of illuminator or its system, more particularly, to a kind of interior lens structure preventing LED direct projection from forming speck, for the car light using LED light source and interior lens it is characterised in that interior lens is lens in discrete type；Fillet position at the wall thickness mutation of lens in discrete type, it is provided with the raised light-blocking structure of LED light source, light-blocking structure blocks the LED direct projection light projecting the fillet position at wall thickness mutation, prevents LED direct projection light from forming speck in interior outer surface of joining after the focusing of fillet position.Using the light-shielding structure being arranged on fillet position at wall thickness mutation, solving the interior lens of discrete type because of the speck that direct projection light focusing causes affects the technical problem of car light light distribution effect；Potential problems can be evaded falling in the early stage of car light design, not increase the technology difficulty Manufacturing cost of product by light-shielding structure and interior lens integrated injection molding.
Description
Technical field
This utility model is related to functional character or the parts of illuminator or its system, and more particularly, to one kind can prevent
LED direct projection forms the interior lens structure of speck.
Background technology
The interior pairing of discrete type can make lighting more uniform for optical property, also obtains increasingly in light fixture
Many utilizations.Chinese utility model patent " lens structure in a kind of LED " (utility model patent number：
ZL201020158311.8 Authorization Notice No.：CN201672444U) disclose lens structure in a kind of LED, for coordinating car
With position lamp or day portable lighter tubulose decorative circle moulding, including light collecting part it is characterised in that lens structure is by gathering in described LED
Light portion, connecting portion, direction controlling portion three part composition, described interior lens totally becomes "] " box-like scrobicula channel-shaped.This utility model
Advantage be that structure is simple, it is possible to achieve the effectively utilizes of light.But, as shown in Fig. 2 lens in existing discrete type
2 structure has 22 at wall thickness mutation, and at wall thickness mutation, 22 back side forms the fillet position being located in LED light line direct projection area 3,
The light that LED light source 1 sends beats on fillet position formation lens focuss effect, focus on light be incident upon in join on outer surface 21
Form speck.The speck that this LED direct projection causes compromises the uniformity of luminous intensity distribution, directly affects the light distribution effect of car light.
Utility model content
The purpose of this utility model is to provide a kind of structure preventing lens speck in car light, solves the interior of discrete type
Lens with produce the speck that causes of LED direct projection and affect the technical problem of car light light distribution effect.
This utility model solves above-mentioned technical problem and be employed technical scheme comprise that：
A kind of structure preventing lens speck in car light, for the car light using LED light source and interior lens, its feature
It is that described interior lens is lens in discrete type；Fillet position at the wall thickness mutation of lens in discrete type, if
Have towards the raised light-blocking structure of LED light source, described light-blocking structure blocks and projects fillet position at wall thickness mutation
LED direct projection light, prevents LED direct projection light from forming speck in interior outer surface of joining after the focusing of fillet position.
One kind preferably technical scheme preventing the structure of lens speck in car light of the present utility model it is characterised in that
The radiused surface from wall thickness mutation for the described light-blocking structure is raised, extends to the direct projection between LED light source and wall thickness mutation
In light path；The height of projection of light-blocking structure projects formed shading region, can join outer surface interior not less than LED direct projection light
Focus on the LED light line direct projection area forming speck.
A kind of superior technique scheme preventing the structure of lens speck in car light of the present utility model it is characterised in that
Described light-blocking structure is the light conductor with interior lens integrated injection molding；Project the LED direct projection light on light-blocking structure,
Conduction through light-blocking structure and interior lens and multiple refraction/reflection join outer surface in being distributed to, and form luminous intensity distribution and uniformly light
Face.
The beneficial effects of the utility model are：
The structure preventing lens speck in car light of the present utility model, using being arranged on fillet position at wall thickness mutation
Light-shielding structure, solve the interior lens of discrete type with the speck that causes because of direct projection light focusing affect car light light distribution effect
Technical problem；Described light-shielding structure and interior lens integrated injection molding, can ask potential in the early stage of car light design
Topic evades falling, and does not increase the technology difficulty Manufacturing cost of product.
Brief description
Fig. 1 is the schematic diagram preventing the structure of lens speck in car light of the present utility model；
Fig. 2 is that in existing car light, lens causes the schematic diagram of speck due to LED direct projection light focusing.
The labelling of each part of above in figure：1-LED light source, lens in 2-, join outer surface in 21-, 22- wall thickness is mutated
Place, 23- light-blocking structure, 3-LED light direct projection area, 31- shading region.
Specific embodiment
For better understanding of technique scheme of the present utility model, enter traveling one with reference to the accompanying drawings and examples
Step ground describes in detail.
An embodiment preventing the structure of lens speck in car light of the present utility model is as shown in figure 1, one kind prevents
The structure of lens speck in car light, for the car light using LED light source 1 and interior lens 2, described interior lens 2 be from
Lens in scattered type；22 fillet position at the wall thickness mutation of lens in discrete type, is provided with LED light source 1 side raised
Light-blocking structure 23, described light-blocking structure 23 blocks the LED direct projection light at the fillet position projecting at wall thickness mutation 22, prevents
Only LED direct projection light forms speck in interior outer surface 21 of joining after the focusing of fillet position.
The embodiment preventing the structure of lens speck in car light of the present utility model according to Fig. 1, described gear
Photo structure 23 from wall thickness mutation 22 radiused surface raised, the direct light between extending to 22 at LED light source 1 and wall thickness mutation
Lu Shang；The height of projection of light-blocking structure 23 projects formed shading region 31, can join appearance interior not less than LED direct projection light
Face 21 focuses on the LED light line direct projection area 3 forming speck.
The embodiment preventing the structure of lens speck in car light of the present utility model according to Fig. 1, described gear
Photo structure 23 is the light conductor with interior lens 2 integrated injection molding；Project the LED direct projection light on light-blocking structure 23, warp
The conduction of light-blocking structure 23 and interior lens 2 and multiple refraction/reflection join outer surface 21 in being distributed to, and form luminous intensity distribution and uniformly send out
Bright finish.
Those of ordinary skill in the art is it should be appreciated that above embodiment is intended merely to illustrate that this practicality is new
The technical scheme of type, and be not used as being to restriction of the present utility model, any based on connotation of the present utility model to
Go up change, the modification that described embodiment is made, all will fall in scope of the claims of the present utility model.
