Description
Technical field
Optical technical field is the utility model is related to, especially a kind of anti-dazzle optical sheets of LED.
Background technology
Dazzle is a kind of visual condition, easily causes eye uncomfortable or reduces the ability of observation important objects, typically
For be by Luminance Distribution is inappropriate, brightness amplitude of variation is too big, space and to be caused the time on there is the reason such as extremely contrasting
's.Dazzle can cause visual impairment and other disease of eye, influence the quality of people's Working Life, and the ancestor of Green Lighting Project
Purport is just to provide comfortable, safe, beneficial lighting environment, to promote the operating efficiency of people, physical and mental health.Therefore, anti-dazzle
It is the indispensable problem of Green Lighting Project, and modern lighting fixtures design indispensable key element.
A kind of existing anti-dazzle tabula rasa is by opening up some shapes such as triangular pyramid, rectangular pyramid or hexagonal pyramid in plate face
Etc. the concaveconvex structure of shape, this kind of anti-dazzle plate surface structure is than realization more difficult to process, the optics plate construction of this kind of shape
Production either roll-in or injection molding all can cause the difficulty of processing of anti-dazzle tabula rasa and cost to greatly improve；It is another kind of be
Add the complicated method such as medium or surface frosted processing on sheet material to make, although this way efficiently solves asking for dazzle
Topic, but can hinder light by, and can not meet light fixture detection in anti-dazzle index requirement.Above method all can not yet
Distribution curve flux is adjusted, it is impossible to meet requirement of the different lamps to anti-dazzle index.
Utility model content
The technical problems to be solved in the utility model is：In order to solve the difficulty of processing of anti-dazzle tabula rasa in the prior art it is big,
The problem of cost is high and can not adjust anti-dazzle index, now provides a kind of anti-dazzle optical sheets of LED.
Technical scheme is used by the utility model solves its technical problem：A kind of anti-dazzle optical sheets of LED, including it is transparent
The substrate of material, a surface of the substrate is outwardly some cones, and the cone gathers on substrate in array,
The circular conical surface of two neighboring cone is interlaced.
Glare prevention structure is designed as the densely covered cone of array in this programme, greatly reduces the anti-dazzle optical sheets of LED
Manufacture difficulty, it is specific as follows：Conical bore directly is drilled out with drill bit on the surface of roller or mould, is drilled out on roller or mould
The distribution of conical bore and size are consistent with the cone on substrate, then carry out roll-in or extrusion injection molding, due to conical bore
Manufacturing process is more simple, can directly be drilled out using drill bit, therefore, reduces the manufacture difficulty of the anti-dazzle mold for optical plate of the LED,
So as to indirectly reduce the manufacture difficulty of the anti-dazzle optical sheets of LED；
For the recessed of the shapes such as triangular pyramid, rectangular pyramid or the hexagonal pyramid on anti-dazzle on traditional anti-dazzle optical sheets of LED
Male structure, the anti-dazzle optics plate surface structures of this kind of LED cause the axis and level of pyramid than realization more difficult to process
Face has certain angle of inclination, and this can not undoubtedly make diversified light distribution, in other words, as traditional LED is anti-dazzle
Optical sheet can not make production adjustment according to the requirement of light distribution；
Further, the axis of some cones is mutually parallel.
Further, the axis of some cones tilts along different directions.
Preferably, the included angle A between the axis and horizontal plane of the cone is 30~90 °.
The beneficial effects of the utility model are：The anti-dazzle optical sheets of LED of the present utility model are by direct in die surface
Conical bore is drilled out with drill bit, then is extruded, injection molding, enormously simplify the manufacture difficulty of anti-dazzling plate, effective reduction
The production cost of the anti-dazzle optical sheets of LED, and anti-dazzle light effect is strong, while the angle of cone can be conveniently adjusted to be matched somebody with somebody
The adjustment of light curve and anti-dazzle index.

Embodiment
The utility model is described in further detail presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram,
Only illustrate basic structure of the present utility model in a schematic way, therefore it only shows the composition relevant with the utility model, direction
With can be only used for helping the description to the feature in accompanying drawing with reference to (for example, upper and lower, left and right, etc.).Therefore, not limiting
