The specific embodiment
See also Fig. 1, it is the structure side view of the utility model diffusion structure the first preferred embodiment.Diffusion structure 1 comprises a first surface 11 and with respect to a second surface 12 of first surface 11, and is formed with a speckle (Speckle) layer 13 on the first surface 11, and is formed with a grating (Grating) layer 14 on the second surface 12; Wherein, grating layer 14 is between a light source 9 and speckle layer 13, so that a plurality of light beam L1 that export from light source 9 can pass through in sequentially grating layer 14 and the 13 backward outer output of speckle layer.
Moreover, grating layer 14 and speckle layer 13 comprise respectively a plurality of gratings and a plurality of speckle, in this preferred embodiment, those gratings and those speckles are distributed in respectively whole and first surface 11 whole of second surface 12, but be not limited with above-mentioned distribution form, this ought also can be carried out by the art those of ordinary skill the variation design of any equalization according to practical application request, can only be distributed in the part surface of second surface 12 such as those gratings, or those speckles can only be distributed in the part surface of first surface 11, and form or the form of speckle distribution that above-mentioned grating distributes can be the form of continuity distribution or the form that a discontinuity distributes.
In addition, grating layer 14 can see through any one in the little shadow of full figure (holographic microlithography) technology, electronics etching technique, laser beam Writing Technology, the little shadow of phase place light shield (phase mask microlithography) technology, little shaping (micro-molding) technology and full figure interference (holographic interferometry) technology and be formed on the diffusion structure 1.
Again, in this preferred embodiment, 1 one-tenth tabular of diffusion structure, and light source 9 can be for by the formed light source of a plurality of light emitting diodes (among the figure indicate), or be by the formed light source of a plurality of laser cells (not indicating among the figure), and light source 9 is one to make its a plurality of light beam L1 that export directly be projected to the directly-down light source of diffusion structure 1, but above-mentioned only is an embodiment, and this ought also can be carried out by the art those of ordinary skill the variation design of any equalization according to practical application request.
Next creation spirit of the present utility model and diffusion principle are described.When a plurality of light beam L1 that export when light source 9 are projected to grating layer 14, those light beams L1 can produce diffraction and scattering on those gratings on the grating layer 14, so that each in those light beams of reason L1 formed a plurality of " point " light source is converted to more " point " light source, and then so that passed those light beams L1 integral body behind the grating layer 14 and appear to just like the visual effect as the babysbreath, so those " point " light sources form " face " light source jointly.
Yet, because those light beams L1 can produce dispersion on those gratings on the grating layer 14, so above-mentioned visual effect just like babysbreath can present with polychrome (just like seven color effects as the rainbow); And the light beam after those produce dispersions is when then being projected to speckle layer 13, and those speckles of speckle layer 13 can provide a light mixing function to those light beams that produces after the dispersion, and then so that by speckle layer 13 outwards the light of output all become uniformly mixed white light.
What specify is, arbitrary grating on the grating layer 14 has the grating parameter group corresponding with it all separately, it can comprise in the grating degree of depth, raster pitch (pitch), grating work period (duty cycle) and the grating orientation at least one, want to be formed at the grating parameter group of each grating on the diffusion structure 1 by control, but then modulation goes out suitable light diffusion angle, light diffusion area, light type and x-ray diffraction efficient.
Furthermore, see also Fig. 2～Fig. 4, the distribution schematic diagram of a plurality of spot lights that it forms in response to a plurality of gratings for the single point light source.Fig. 2 has illustrated that the grating degree of depth is D1 and the raster pitch diffraction efficient when being T1, and namely the single point light source is that the spot light that D1 and raster pitch can form-1 rank, 0 rank and 1 rank when being T1 distributes in response to the grating degree of depth; Fig. 3 has illustrated that the grating degree of depth is D2 and the raster pitch diffraction efficient when being T1, because grating depth D 2〉grating depth D 1, so the single point light source is that the spot light that D2 and raster pitch can form-3 rank ,-2 rank ,-1 rank, 0 rank, 1 rank, 2 rank and 3 rank when being T1 distributes in response to the grating degree of depth; Fig. 4 has illustrated that the grating degree of depth is D2 and the raster pitch diffraction efficient when being T2, because raster pitch T2＜raster pitch T1, so the single point light source is that the spot light that D2 and raster pitch can form-5 rank ,-4 rank ,-3 rank ,-2 rank ,-1 rank, 0 rank, 1 rank, 2 rank, 3 rank, 4 rank and 5 rank when being T2 distributes in response to the grating degree of depth.What specify is, the suitable grating degree of depth and raster pitch can make the spot light on arbitrary rank all have identical brightness, also can according to must adjust the brightness on each rank, the spot light size of painting on the figure but not only can be identical or different in order to limit spot light brightness of the present utility model only in order to explanation.
Moreover, but go out a plurality of light beams in by grating layer and the light type of the common formation of institute after occuring mutually to interfere by the grating parameter group of each grating of control and/or by the distribution modulation of those gratings of control.See also Fig. 5～Fig. 6, its for a plurality of light beams because occuring mutually to interfere the common light type schematic diagram that forms when the grating.Fig. 5 has illustrated a plurality of light beams to interfere because quadrature occurs when the grating, thereby jointly forms the square light type; Fig. 6 has illustrated a plurality of light beams to interfere the interference of light that angle is 60 degree because of by grating the time, thereby jointly forms X-shaped light type.
Be with, those skilled in the art can design grating layer 14 according to the actual demand specification of diffusion structure 1, so wantonly two gratings on the grating layer 14 are not must be to have identical grating parameter group or have not identical grating parameter group.
Moreover, can control speckle intensity on the speckle layer 13 by the roughness of first surface 11 of control diffusion structure 1, and then reach different light mixing effects, so wantonly two speckles on the speckle layer 13 are not must be to have identical speckle intensity or have not identical speckle intensity.
According to above explanation, the utility model diffusion structure 1 can reach penetrance 80%, mist degree 100% and light diffusion angle θ 1 is the effects of 170 degree, and existing effect is improved the deficiency of existing diffusion structure 1, is in fact one to have the lighting engineering of industry applications.Be with, the utility model diffusion structure can be applicable to lighting device, such as wall lamp, advertising lamp, lampshade etc.; Or be to be applied to backlight module, such as liquid crystal indicator etc.; Or be to be applied to projection arrangement etc.
See also Fig. 7, it is applied to the schematic diagram of straight-down negative lighting device for diffusion structure shown in Figure 1.Straight-down negative lighting device 2 can be an interior illuminator or an outdoor illumination, and comprise a plurality of light emitting diodes 91 and diffusion structure 1, because the utility model can increase the light diffusion angle of diffusion structure 1, so if straight-down negative lighting device 1 is applied on the road lamp device, then the spacing of adjacent two street lamp devices just can widen, and then can reduce the quantity of road lamp device.
