Abstract

nullThe utility model discloses a kind of anti-dazzle tabula rasa of concavees lens，It is characterized in that，Including transparent base diaphragm，In the molded inner concave shape sphere concavees lens gathered of described transparent base diaphragm one surface roll，Described sphere concavees lens are 90 ° of densely covered arrangements of intersection，Described sphere concavees lens diameter 60～80 μm，The sphere degree of depth 20～35 μm，Described sphere concavees lens gap has the small sphere of exterior rearview concavees lens of the indent of roll-forming、One in positive triangular pyramid or positive rectangular pyramid or its combine arbitrarily，This utility model，Optical lens is utilized to form the principle of the virtual image at light source，Utilize two or more lens a point source to be formed the two or more virtual image simultaneously，A point source is made the when of visually seeing, to find out the two or more point source virtual image，Alleviate the point source stimulation to eyes，Solve the glare problem of various occasion，The problem not simultaneously being produced as light diffusion and reduce light transmittance.

Description

A kind of anti-dazzle tabula rasa of concavees lens

Technical field

This utility model relates to optical field, particularly relates to a kind of anti-dazzle tabula rasa of concavees lens.

Background technology

It is known that LED light fixture has the feature such as energy-saving and environmental protection, long-life, it it is the revolutionary product of field of illuminating lamps Product.But the light source being because LED light fixture is point source, light is the strongest, so the most dazzling, and the problem that there is dazzle.As Fruit normally to use the problem that LED light fixture have to solve dazzle.

Present stage LED light fixture is mainly made up of LED light source, wiring board, electrical equipment and housing and lampshade etc., in order to disappear Except dazzle, current production firm carries out special processing at lamp housing portion, makes LED light source the most excessively sting through the light of lampshade output Eye, wherein conventional means are included in transparent material and are made by the interpolation method such as medium or surface frosted process, this Although kind of way efficiently solves the problem of dazzle, but can hinder passing through of light, it is substantially reduced the light transmission efficiency of lampshade, makes The light utilization ratio of LED light fixture reduces, cannot effectively play its energy-saving effect.If it is desired that make good use of LED light fixture, give full play to Its energy-conservation effect, it is necessary to solve anti-dazzle present on current LED light fixture and the contradiction of light transmission efficiency reduction.

Utility model content

The purpose of this utility model is to solve shortcoming present in prior art, and a kind of concavees lens proposed are anti-dazzle Tabula rasa.

To achieve these goals, this utility model adopts the technical scheme that

A kind of anti-dazzle tabula rasa of concavees lens, it is characterised in that include transparent base diaphragm, in described transparent base diaphragm one table The inner concave shape sphere concavees lens that face roll-forming gathers, described sphere concavees lens are 90 ° and intersect arrangement of gathering, and described sphere is recessed Lens diameter 60～80 μm, the sphere degree of depth 20～35 μm, described sphere concavees lens gap has indent little of roll-forming One in sphere concavees lens, positive triangular pyramid or positive rectangular pyramid or its combine arbitrarily.

Further, described small sphere of exterior rearview concavees lens diameter 30～50 μm, the sphere degree of depth 10～20 μm.

The anti-dazzle tabula rasa of this utility model concavees lens, arranges less concavees lens or positive Rhizoma Sparganii in sphere concavees lens gap Cone, positive rectangular pyramid, prevent light leak, thus enhance anti-dazzle tabula rasa anti-dazzle function.

Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole Embodiment.

Embodiment 1: with reference to Fig. 1～Fig. 4, a kind of anti-dazzle tabula rasa of concavees lens, including transparent base diaphragm 1, in described transparent The inner concave shape sphere concavees lens 1-1, sphere concavees lens 1-1 that base material diaphragm 1 one surface roll is molded gathers is 90 ° and intersects densely covered Arrangement, sphere concavees lens 1-1 diameter 60～80 μm, the sphere degree of depth 20～35 μm, sphere concavees lens 1-1 gap has and is rolled into The small sphere of exterior rearview concavees lens 1-2 of the indent of type, small sphere of exterior rearview concavees lens diameter 30～50 μm, the sphere degree of depth 10～20 μm.

Embodiment 2: with reference to shown in Fig. 5, a kind of anti-dazzle tabula rasa of concavees lens, including transparent base diaphragm 1, in described transparent base The inner concave shape sphere concavees lens 1-1, sphere concavees lens 1-1 that material diaphragm 1 one surface roll is molded gathers is 90 ° of densely covered rows of intersection Row, sphere concavees lens 1-1 diameter 60～80 μm, the sphere degree of depth 20～35 μm, sphere concavees lens 1-1 has roll-forming in gap The positive triangular pyramid of indent or positive rectangular pyramid 1-3.

The above, only this utility model preferably detailed description of the invention, but protection domain of the present utility model is not Being confined to this, any those familiar with the art is in the technical scope that this utility model discloses, according to this practicality Novel technical scheme and utility model thereof conceive equivalent or change in addition, all should contain at protection model of the present utility model Within enclosing.

Claims

1. the anti-dazzle tabula rasa of concavees lens, it is characterised in that include transparent base diaphragm 1, in described transparent base diaphragm 1 one table The inner concave shape sphere concavees lens 1-1, described sphere concavees lens 1-1 that face roll-forming gathers is 90 ° and intersects arrangement of gathering, described Sphere concavees lens 1-1 diameter 60～80 μm, the sphere degree of depth 20～35 μm, described sphere concavees lens 1-1 gap has and is rolled into One in the small sphere of exterior rearview concavees lens of the indent of type, positive triangular pyramid or positive rectangular pyramid or its combine arbitrarily.
