Description
Technical field
The present invention relates to the specular reflection of light, particularly relate to a kind of reverberator.
Background technology
At present, efficient reflective mirror is choose high purity specular aluminium as reflecting material mostly, and this kind of material belongs to specular reflective material. Also have and adopt the frosting as plane of reflection, but this kind of reverberator reflection efficiency is very low.
In real life, specular reflective material makes light fixture reflective mirror and requires that the precision made is very high, make and slightly just form blackening and Crape ring with design deviation, general requirement deviation is no more than the 0.2% of the own yardstick of reverberator, if the yardstick of reflective mirror own is at below 10cm, require that processing error is no more than 0.2mm, this requirement increases the difficulty of processing, cause yield rate lower.
For multiple luminous point light source, such as LED/light source, it is very big that specular reflective material makes reflective mirror design difficulty, through repeatedly designing, simulate and revise the luminous intensity distribution that just can reach needs.
In view of this, prior art haves much room for improvement and improves.
Summary of the invention
In view of deficiency of the prior art, the object of the invention is to provide a kind of reverberator. It is intended to solve the difficulty of processing that in prior art, reverberator exists big, the problems such as luminous intensity distribution difficulty.
For this reason, the present invention provides following technical scheme:
A kind of reverberator, it is applicable to multiple luminous point light source, wherein, described reverberator comprises: one rotates the curved surface that formed as the reflector body of plane of reflection, some reflective surfaces and the nano coating that is coated on described reflective surface taking cubic curve, and described reflective surface is placed on reflector body curved surface.
The cubic curve equation of described formation curved surface is
��
The material opacifying power of nano coating described in described nano material is not more than 100g/m2��
The shape of described reflective surface is flakey, and is sheen reflective surface.
Each flakey reflective surface area is not more than the 1/50 of the reflective surface total area, is not less than the 1/80 of the reflective surface total area.
The useful effect of hinge structure of the present invention be mainly reflected in following some:
1, owing to reflecting material is coating material, not being strict with by base material, reverberator base material can make of plain metal, plastic cement, greatly reduces production cost.
2, nanometer coating material sticking power is incited somebody to action, and coating processes is simple, is easy to realize producing in enormous quantities.
3, the formation increasing retroaction of visible ray centre wavelength and material particle size distribution are normal distribution by high-reflectivity nanometer diffuse reflection material median size, increase retroaction and just contain visible light wave range, if particle diameter is excessive or excessively little composition reduces as far as possible, material opacifying power is not more than 100g/m2, it is ensured that high-reflectivity diffuse reflection material reflectivity reaches 96%, reflection efficiency height, and reflection substantially increases light fixture efficiency.
4, the bus cubic curve equation of this invention reflective mirror is:
Equation is defined in [0,14] interval, bus rotates the reflective surface obtaining reflective mirror around x-axis, according to equation can calculate every any tangential equation and normal equation, i.e. the light that any send out a line and all can calculate every, and then the light source being placed in x-axis sends is mapped on reflective surface reflected ray and can also calculate, therefore, luminous intensity distribution of the present invention can adopt 3 curves to be the bus of reflector shape when designing, and determines by 4 parameters, can design the luminous intensity distribution of multiple luminous point light source more accurately.
5, diffuse surface is cosine light-emitting area, and requirement on machining accuracy is not high, there will not be the situation such as blackening or Crape ring in luminous intensity distribution.
Accompanying drawing explanation
Fig. 1 is reflector structure schematic diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described further, there is shown a kind of implementation of the present invention, protection scope of the present invention can not be confined to this kind of enforcement mode.
Fig. 1 is reflector structure schematic diagram of the present invention. as described in Figure 1, 1 is reflector body, 2 is flakey reflective surface, 3 is cubic curve, wherein, reflector body 1 have one rotated the curved indentations obtained by cubic curve 3, and curved indentations has carried out symmetry division, partitioning scheme is as follows: first select a cubic curve 3 as bus, then be rotating shaft taking turning axle by this bus is divided into 36 curved surfaces being connected with 10 degree of angle rotating 360 degrees by curved surface, finally by the plane being perpendicular to rotating shaft, curved surface is carried out secondary splitting, spacing between the plane of secondary splitting can be a fixing value, if value is 2, then the curved surface with corner can be partitioned on curved surface, the corner of the curved surface finally obtained according to segmentation by flakey reflective surface 2 is placed, this reverberator can be obtained, certainly, each reflective surface 2 also to be applied high-reflectivity diffuse-reflectance nano material.
Further, best cubic curve equation is:
Above-mentioned curvilinear equation is defined in [0,14] interval, bus rotates the reflective surface obtaining reflective mirror around x-axis, according to equation can calculate every any tangential equation and normal equation, i.e. any send out a line and all can calculate every, the light that the light source being placed in x-axis sends is mapped on reflective surface reflected ray and just can calculate.
Preferably, owing to high-reflectivity nanometer diffuse reflection material size distribution is normal distribution, and increase retroaction just contain visible light wave range, visible ray centre wavelength is formed and increases retroaction by high-reflectivity nanometer diffuse reflection material median size, if ensure that the composition that particle diameter is excessive or excessively little reduces and the nano material opacifying power of nano coating is not more than 100g/m2 as far as possible, high-reflectivity diffuse reflection material reflectivity can be realized and reach 96%, substantially increase light fixture efficiency.
Preferably, reflective surface shape is flakey, and is sheen reflective surface, it may also be useful to flakey reflective surface can make diffuse surface be cosine light-emitting area, this reduces requirement on machining accuracy, also there will not be the situation such as blackening or Crape ring in luminous intensity distribution.
Preferably, flakey reflective surface area is not more than the 1/50 of the reflective surface total area, is not less than the 1/80 of the reflective surface total area, if flakey area is too big, then can affect luminous intensity distribution, if too little, then not have sheen effect.
Should be understood that; the application of the present invention is not limited to above-mentioned citing; for those of ordinary skills, it is possible to improved according to the above description or convert, improve based on constant all these of core of the present invention and conversion all should in protection scope of the present invention.
