Description
Technical field
The present invention relates to anti-dazzle plate technique field, especially a kind of anti-dazzle tabula rasa with different base angle pyramids.
Background technology
Studies have shown that the side base angle of pyramidal structure is bigger in anti-dazzle tabula rasa, then there is the direction quilt of more light earthward
Refraction, the light of wide-angle are refracted, and UGR values reduce.However, quadrangular pyramid base angle forms range will produce secondary lobe in certain section
Sidelight leakage phenomenon, when quadrangular pyramid base angle is bigger, light back to light incoming direction on recirculation phenomenon increase, generate
More reflections, cause light efficiency to reduce.When quadrangular pyramid base angle is too big, meet UGR conditions, but light efficiency reduces.In addition, working as quadrangle
When cone base angle is too small, the reduction of light efficiency is minimized, but cannot meet UGR conditions.As described above, in order to reduce UGR values, such as
Fruit quadrangular pyramid base angle is too big, then light efficiency reduces.Moreover, also reducing by the area of light radiation, i.e. light-emitting area.In the situation
Under, more lighting devices are needed to illuminate identical region.I.e. under normal conditions, quadrangular pyramid base angle is bigger, then UGR values drop
It is low, but light efficiency also reduces and (makes comparisons, be less than 90%) with diffuser plate.Therefore, it should the angle-determining by quadrangular pyramid base angle is,
The reduction of light efficiency can be minimized, and will be maximized by the area of light radiation, while still meet UGR standards.
Invention content
The object of the present invention is to provide a kind of anti-dazzle tabula rasas with different base angle pyramids, can be minimum by the reduction of light efficiency
Change, and will be maximized by the area of light radiation, while still meeting UGR standards.
In order to solve the above technical problems, the object of the present invention is achieved like this：
A kind of anti-dazzle tabula rasa with different base angle pyramids involved in the present invention, including anti-dazzle tabula rasa ontology and it is set to it
On anti-dazzle microstructure unit；The anti-dazzle microstructure unit includes the positive rib with different base angles for setting quantity
Cone；The base angle of the orthopyramid is from side to the other side in increased trend after first reducing.
As a further illustration of the above scheme, the anti-dazzle microstructure unit is by the positive rectangular pyramid with different base angles
Composition.
The beneficial effects of the invention are as follows：The present invention relates to a kind of anti-dazzle tabula rasas with different base angle pyramids, are symmetrical arranged
There are the positive rectangular pyramid that base angle is reduced successively by both sides to center, the larger positive rectangular pyramid in base angle that can reduce UGR values, meets and shine
Requirement of the bright device to UGR values；The smaller positive rectangular pyramid in base angle may make the reduction of light efficiency to minimize, and can meet lighting device pair
The requirement of light efficiency.Can both the reduction of light efficiency be minimized by being equipped with the lighting device of the anti-dazzle tabula rasa, and will be by light radiation
Fabric maximize, while remaining to meet UGR standards.
Description of the drawings
Fig. 1 is the sectional view of microstructure unit in the present invention.
Label is described as follows in figure：The anti-dazzle tabula rasa ontologies of 1-, 2- anti-dazzle micro-structures.
Specific implementation mode
Present invention will be further explained below with reference to the attached drawings and specific examples.
Embodiment one
In conjunction with Fig. 1, elaborate to the present embodiment.It is a kind of anti-with different base angle pyramids involved by the present embodiment
Dazzle plate, including anti-dazzle tabula rasa ontology and the anti-dazzle microstructure unit that is arranged on.Anti-dazzle microstructure unit has several
Anti-dazzle micro-structure forms.
Include the positive rectangular pyramid with different base angles for setting quantity in each anti-dazzle microstructure unit, orthopyramid
Base angle from side to the other side in increased trend after first reducing, i.e., the trend of base angle size be from greatly to it is small, again from as low as big,
And the base angle of positive rectangular pyramid is arranged symmetrically.In the present embodiment, the positive rectangular pyramid in anti-dazzle microstructure unit has 10, from
The base angle of the positive rectangular pyramid in side to the other side be followed successively by 50 °, 40 °, 30 °, 20 °, 10 °, 20 °, 30 °, 40 °, 50 °, 60.Different bottoms
The bottom surface length of side of the positive rectangular pyramid at angle is identical.Base angle is the angle of positive rectangular pyramid side and bottom surface in embodiment.At this
In embodiment, the length of side of regular quadrangle is 1.53mm.
In other embodiments, the bottom surface of each micro-structure in glare prevention structure can be other regular polygons.
In microstructure unit in anti-dazzle micro-structure, the pyramidal structure that base angle is big and base angle is small is configured simultaneously according to certain angle, this
Sample can guarantee that UGR values are relatively low, can also meet the higher condition of light efficiency.
Embodiment two
In conjunction with Fig. 1, elaborate to the present embodiment.It is a kind of anti-with different base angle pyramids involved by the present embodiment
Dazzle plate, difference lies in the positive rectangular pyramid in anti-dazzle microstructure unit has 10, just from side to the other side with embodiment
The base angle of rectangular pyramid is followed successively by 40 °, 35 °, 30 °, 25 °, 20 °, 25 °, 30 °, 35 °, 40 °, 45 °.
