Abstract
The utility model relates to a kind of optical elements, car light and automobile for car light, belong to automotive lamp product field.A kind of optical element for car light, the optical element include transparent part and opaque section, and the surface of the transparent part is coated with scattering coating.A kind of car light, the optical element comprising being previously used for car light.A kind of automobile includes car light above-mentioned.The utility model replaces directly adding scattering particles in transparent substrate by spraying scattering coating, so that only needing to prepare the scattering coating and diluent of the benchmark concentration of seldom type, the concentration of allotment scattering coating according to production needs, the various transmitances requirement that different product can be met, reduces management and stock cost.
Description
Technical field
The utility model relates to automotive lamp product field, in particular to a kind of optical element, car light and automobile for car light.
Background technique
In existing automotive lamp product, in order to realize uniform lighting effect, optical element (interior lens etc.) can generally make
The material of scattering particles is added in transparent substrate (PC, PMMA etc.).Material is usually white or red.Light is passing through this
It can be spread when kind material, thus cause one kind respectively to uniform lighting effect.But this material also has disadvantage, in order to suitable
Answer the optical demands and appearance demand of different product, it is necessary to use the scattering material of different formulations (transmitance).And scattering material
Formula be to be prepared at material maker.In this way, the scattering material of multiple formulations must be laid in.Increase management, material
Cost, reduce the flexibility of management.
Utility model content
The purpose of this utility model is that in view of the above-mentioned problems, provide it is a kind of for the optical element of car light, car light and
Automobile, it is only necessary to which the coating and diluent for preparing seldom type can meet the different of various products and require.
Purpose of the utility model is realized as follows:
A kind of optical element for car light, the optical element include transparent part and opaque section, described transparent
Partial surface is coated with scattering coating.
Preferably, the surface includes inner surface and/or outer surface.
Preferably, the scattering coating includes one of polyurethane, acrylic resin, organic siliconresin and epoxy resin
Or more than one composition.
Preferably, the transmitance of the transparent part is determined by the concentration of the scattering coating, described to scatter the dense of coating
The transmitance for spending the more low then described transparent part is higher.
Preferably, the scattering coating is by addition diluent to reduce concentration.
Preferably, the diluent includes one in deionized water, ethyl alcohol, n-butanol, propylene glycol monomethyl ether and ethyl acetate
Kind or more than one composition.
Preferably, the optical element includes interior lens.
The invention also discloses a kind of car lights, include aforementioned any optical element for car light.
The invention also discloses a kind of automobiles, include car light above-mentioned.
The utility model has the following beneficial effects: only needing to prepare scattering coating and the dilution of the benchmark concentration of seldom type
Agent, the concentration of allotment scattering coating, can meet the various transmitances requirement of different product, reduce management according to production needs
With stock cost.
Detailed description of the invention
Fig. 1 is schematic cross-section of the utility model for one embodiment of optical element of car light.
Specific embodiment
The various embodiments of the utility model will be described with reference to the drawings.In specification and attached drawing, there is similar knot
Structure or the element of function will be indicated with identical component symbol.It is appreciated that attached drawing is only to provide reference and description to use, not
For being limited to the utility model.The size shown in attached drawing is only to be convenient for clearly describing, and does not limit ratio
Relationship carries out exhaustive explanation to the utility model, nor limiting the scope of the utility model.
In the description of the present invention, it should be understood that term " on ", "lower", "front", "rear", "left", "right",
The orientation or positional relationship of the instructions such as "vertical", "horizontal", "top", "bottom", "inner", "outside" be orientation based on the figure or
Positional relationship is merely for convenience of describing the present invention and simplifying the description, rather than the device or member of indication or suggestion meaning
Part must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.
Fig. 1 shows an embodiment of the optical element for car light.
As shown in Figure 1, a kind of optical element for car light, the optical element includes transparent part 1 and opaque portion
Divide 2, the surface of the transparent part 1 is coated with scattering coating, dispersion effect needed for realizing car light with this.Usually, this
In the optical element refer to interior lens, the moulding of optical element is unlimited.
Specifically, scattering coating can be coated in inner surface or the outer surface of transparent part 1, or can also be coated in simultaneously
The inner surface and the outer surface of bright part 1, determines according to actual needs.The inner surface and the outer surface described here is opposite, such as
Can define towards the car light light direction of the launch is inner surface, otherwise as outer surface.
The type for scattering coating is unlimited, can be one in polyurethane, acrylic resin, organic siliconresin and epoxy resin
Kind or more than one composition., according to actual needs depending on
In order to reduce management and stock cost, the stock of various scattering coating should not be too many.According to the dense of scattering coating
Degree determines the transmitance of transparent part, and the more low then transmitance of concentration is higher, therefore usually requires the base for first determining scattering coating
Quasi- concentration, the benchmark concentration are usually the maximum concentration that may be used.
When needing to improve the transmitance of transparent part, only diluent need to be added in the scattering coating of benchmark concentration to drop
Its low concentration.For example, the benchmark transmitance under the basic concentration of certain coating is 90%, by adding diluent, may make
The transmitance of the coating is improved to 92%.
Diluent can there are many, including one in deionized water, ethyl alcohol, n-butanol, propylene glycol monomethyl ether and ethyl acetate
Kind or more than one composition.
Secondly, the utility model additionally provides a kind of car light, which includes the optical element for being previously described for car light, institute
It states optical element specifically and can be the interior lens of car light.
Finally, the utility model additionally provides a kind of automobile, which includes car light above-mentioned.
Although the foregoing describe specific embodiment of the present utility model, it will be appreciated by those of skill in the art that
This is merely illustrative of, and the protection scope of the utility model is defined by the appended claims.Those skilled in the art
Under the premise of without departing substantially from the principles of the present invention and essence, many changes and modifications may be made,
But these change and modification each fall within the protection scope of the utility model.
