Description
Technical field
The utility model relates to lighting technical field, especially a kind of anti-dazzle with non-rectilinear corner angle cone micro-structure
Plate.
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 non-rectilinear corner angle cone micro-structure, can be by light efficiency
Reduction minimize, and will be maximized by the area of light radiation, and while still meet UGR standard.
In order to solve the above technical problems, purpose of the utility model is realized as follows:
The utility model relates to it is a kind of with non-rectilinear corner angle cone micro-structure anti-dazzle tabula rasa, including anti-dazzle tabula rasa ontology with
And it is set to the pyramid micro-structure on anti-dazzle tabula rasa ontology, the rib of the pyramid is non-rectilinear rib, and the non-rectilinear rib is in interior
Concavity.
As a further illustration of the above scheme, the non-rectilinear rib is broken line.
As a further illustration of the above scheme, the non-rectilinear rib is curve.
The quadrangular pyramid as a further illustration of the above scheme, pyramid is positive.
The beneficial effects of the utility model are: the utility model relates to a kind of with the anti-dazzle of non-rectilinear corner angle cone micro-structure
Tabula rasa is provided with different base angles in the same pyramid micro-structure, and the biggish positive rectangular pyramid in base angle can reduce UGR value, meets and shines
Requirement of the bright device to UGR value；The lesser 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.The lighting device for being equipped with the anti-dazzle tabula rasa can both minimize the reduction of light efficiency, and will be by light radiation
Fabric maximize, while being still able to satisfy UGR standard.
