Description
Technical field
The utility model relates to anti-dazzle plate technique field, especially a kind of anti-dazzle tabula rasa with different base angle pyramids.
Background technique
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 to the ground
Refraction, the light of wide-angle are refracted, and UGR value reduces.However, quadrangular pyramid base angle forms range can generate 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 condition, but light efficiency reduces.In addition, working as quadrangle
When cone base angle is too small, the reduction of light efficiency is minimized, but is not able to satisfy UGR condition.As described above, in order to reduce UGR value, 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 value drops
It is low, but light efficiency is also reduced and (is made comparisons with diffuser plate, less than 90%).Therefore, it should the angle at quadrangular pyramid base angle is determined as,
The reduction of light efficiency can be minimized, and will be maximized by the area of light radiation, while still meeting UGR standard.
Summary of the invention
The purpose of the utility model is to provide a kind of anti-dazzle tabula rasas with different base angle pyramids, can be by the reduction of light efficiency
It minimizes, and will be maximized by the area of light radiation, while still meeting UGR standard.
In order to solve the above technical problems, purpose of the utility model is realized as follows:
A kind of anti-dazzle tabula rasa with different base angle pyramids involved by the utility model, including anti-dazzle tabula rasa ontology and setting
Anti-dazzle microstructure unit thereon；The anti-dazzle microstructure unit include set quantity have different base angles just
Pyramid；The base angle of the orthopyramid is in first to reduce the trend increased afterwards from side to the other side.
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 utility model are: the utility model relates to a kind of anti-dazzle tabula rasa with different base angle pyramids,
It is symmetrically arranged with the positive rectangular pyramid that base angle is successively reduced by two sides to center, the biggish positive rectangular pyramid in base angle can reduce UGR
Value, meets requirement of the lighting device to UGR value；The lesser positive rectangular pyramid in base angle may make the reduction of light efficiency to minimize, and can meet
Requirement of the lighting device to light efficiency.The lighting device for being equipped with the anti-dazzle tabula rasa can both minimize the reduction of light efficiency, and
It will be maximized by the fabric of light radiation, while being still able to satisfy UGR standard.
Detailed description of the invention
Fig. 1 is the sectional view of microstructure unit in the utility model.
Label is described as follows in figure: the anti-dazzle tabula rasa ontology of 1-, 2- anti-dazzle micro-structure.
Specific embodiment
The present invention will be further described in the following with reference to the drawings and specific embodiments.
Embodiment one
In conjunction with Fig. 1, elaborate to the present embodiment.It is a kind of anti-with different base angle pyramids involved in the present embodiment
Dazzle plate, including anti-dazzle tabula rasa ontology and the anti-dazzle microstructure unit being arranged on.Anti-dazzle microstructure unit has several
Anti-dazzle micro-structure composition.
It 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 the trend increased afterwards is first reduced, i.e., the trend of base angle size be from greatly to it is small, again from as low as greatly,
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 is followed successively by 50 °, 40 °, 30 °, 20 °, 10 °, 20 °, 30 °, 40 °, 50 °, 60.Different bottoms
The bottom surface side length of the positive rectangular pyramid at angle is identical.Base angle is positive the angle of rectangular pyramid side and bottom surface in embodiment.At this
In embodiment, the side length 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 value is lower, also be able to satisfy 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 in the present embodiment
Dazzle plate, the difference with embodiment are that the positive rectangular pyramid in anti-dazzle microstructure unit has 10, just from side to the other side
The base angle of rectangular pyramid is followed successively by 40 °, 35 °, 30 °, 25 °, 20 °, 25 °, 30 °, 35 °, 40 °, 45 °.
The preferred embodiments of the present invention have been described in detail above.It should be appreciated that the ordinary skill people of this field
Member according to the present utility model can conceive without creative work makes many modifications and variations.Therefore, all this technology necks
Technical staff passes through logic analysis, reasoning or limited reality according to the design of the utility model on the basis of existing technology in domain
Available technical solution is tested, it all should be within the scope of protection determined by the claims.
