Embodiment
with reference to the accompanying drawings, this LED light emission device is further illustrated.And, should be appreciated that the feature not mutual exclusion of various embodiment described here, and can exist in various combination and transformation process.
as shown in Figure 1, the plate body 2 that LED light emission device comprises light source 1, transparent material is made of dyestuff is scribbled.This plate body 2 comprises exiting surface 3 bottom surface relative with exiting surface 34, side 5 between exiting surface 3 and bottom surface 4 and is positioned at some microstructures of exiting surface 3, and this microstructure is salient point 6.Plate body material can be the polymkeric substance such as polymethylmethacrylate (PMMA), polycarbonate (PC), resin material (resin), glass (glass), organosilicon (silicone), epoxy resin (epoxy), light transmittance at least reaches 70%, and refractive index can be 1.4-1.7.This LED light emission device adopts side light source form, and with side 5 for incidence surface, incidence surface is adjacent with exiting surface 3, and light source 1 and side 5 are oppositely arranged.Light source 1 comprises the monochromatic light solid-state light emitting element of multiple different colours, and the monochromatic light of at least two kinds of different colours can be provided with switching, such as ruddiness, orange light, gold-tinted, green glow, indigo light, blue light or purple LED, its installation form can be SMD (SMD) etc.The light that light source 1 sends incides in plate body 2 via the side 5 of plate body 2, and propagates in plate body 2.Based on total reflection principle, light can to-and-fro movement in plate body 2.The exiting surface 3 of LED light emission device is distributed with some salient points 6, the shape of salient point 6 for having multiple, can be such as triangular pyramids, corner cone, positive tetrahedron, cube etc., this salient point 6 destroys original smooth flat, and can not be totally reflected, so when light touches salient point 6, just LED light emission device can be penetrated out.
fig. 2 shows a kind of structure of embodiment bumps 6, the not coplanar of salient point 6 is coated with the dyestuff 61,62 of different colours, the color of the dyestuff of this different colours is selected from the monochromatic color of the different colours that light source provides, when light passes through the dyestuff of solid color, the light different from this dye colour can by dye absorber, and the light identical with this dye colour then can leach this dyestuff.Such as, on salient point 6 left side, 61 is orchil, on salient point 6, the right side 62 is weld, when light source 1 comprises red-light LED and yellow light LED, the ruddiness that this red-light LED sends is when this salient point 6, ruddiness can leach the left side of this salient point 6, and its shooting angle is α 1, and the gold-tinted that yellow light LED sends then cannot through the left side of this salient point 6; The gold-tinted that this yellow light LED sends is when this salient point 6, and gold-tinted can leach the right side of this salient point 6, and its shooting angle is α 2, and the ruddiness light that red-light LED sends then cannot through the right side of this salient point 6.Like this, the red-light LED of light source and gold-tinted diode are opened, only having the region A of ruddiness, what observer saw only has red light simultaneously; At the Mixed Zone B of ruddiness and gold-tinted, observer is it is seen that the orange-colored light of ruddiness and yellow light mix; And only having the region C of gold-tinted, observer is it is seen that sodium yellow.
fig. 3 shows the structure of another embodiment bumps 6, with Fig. 2 unlike, before dyestuff 61 and 62, be coated with fluorescent material 611 and 621.Fluorescent material 611 and 621 is converted into the monochromatic light of another kind of wavelength for the monochromatic light sent by light source, the color of dyestuff 61 and 62 is respectively the monochromatic color that fluorescent material 611 and 621 inspires.Such as, light source 1 comprises blue-ray LED, and fluorescent material 611 is material blue light being converted to ruddiness, and 61 is orchil; Fluorescent material 621 is material blue light being converted to gold-tinted, and 62 is weld.Like this, only have a kind of monochromatic blue-ray LED as long as open, just can realize, only having the region A of ruddiness, what observer saw only has red light; At the Mixed Zone B of ruddiness and gold-tinted, observer is it is seen that the orange-colored light of ruddiness and yellow light mix; And only having the region C of gold-tinted, observer is it is seen that sodium yellow.
fig. 4 shows an alternative embodiment of the invention, as shown in Figure 4, scribble the plate body 2 that LED light emission device comprises light source 1, transparent material is made of dyestuff, plate body 2 is rectangular structure, and this plate body 2 comprises in the exiting surface 31 of plate body side another exiting surface 32 relative with exiting surface 3, side 5 between exiting surface 31 and exiting surface 32 and the some microstructures 6 being positioned at exiting surface 31 and 32.Preferably, this microstructure 6 can be the combination of concave point, salient point or concave point and salient point, and the shape of concave point or salient point can be cone, triangular pyramids, corner cone, positive tetrahedron, cube, half sphere shape etc.By such setting, this light-emitting device is made to realize double-side, make observer can see the content of this light-emitting device at pro and con, and by arranging different cavity disperse characteristic at pros and cons, the pro and con of this light-emitting device can be made can to show different contents.
in order to make light appear from microstructure as far as possible, and do not spill from other places, the position of microstructure can not had to plate the high material of one deck reflectivity at panel surface, as mercury, Al, Ag, Au, Cu etc., form reflection horizon.
salient point in above-described embodiment can be made by lithographic plate printing method, namely according to required word or pattern form, carries out net-pont design, make egative film, then egative film is printed onto on the surface of exiting surface, finally baking or Ultraviolet radiation, thus forms salient point.Salient point in above-described embodiment also can be formed by mould molding.
concave point in above-described embodiment can carry out semiconductor processing method realization by effects on surface, such as etching, laser engraving, impression etc.So-called engraving method comprises the steps: first to cover layer protecting film at exiting surface; Secondly, by exposure plate-making, development, will remove the diaphragm of etching area; Finally, add chemical solution in the region of removing diaphragm, to reach the effect of dissolved corrosion, thus form concave point.
in addition, those skilled in the art also can do other change in spirit of the present invention, as long as it does not depart from technique effect of the present invention.These changes done according to the present invention's spirit, all should be included within the present invention's scope required for protection.
