The specific embodiment
With reference to the accompanying drawings, further specify this LED light-emitting device.And, should be appreciated that the not mutual exclusion of feature of various embodiment described here, and can in various combinations and transformation process, exist.
As shown in Figure 1, the LED light-emitting device that scribbles dyestuff comprises the plate body 2 that light source 1, transparent material are made.This plate body 2 comprises exiting surface 3, bottom surface 4, the side 5 between exiting surface 3 and bottom surface 4 between relative with exiting surface 3 and is positioned at some micro-structurals of exiting surface 3 that this micro-structural is salient point 6.Plate body material can be the polymer such as polymethyl methacrylate (PMMA), Merlon (PC), resin material (resin), glass (glass), organosilicon (silicone), epoxy resin (epoxy), light transmittance reaches 70% at least, and refractive index can be 1.4-1.7.This LED light-emitting device adopts the side light source form, and 5 are incidence surface take the side, and incidence surface is adjacent with exiting surface 3, and light source 1 is oppositely arranged with side 5.Light source 1 comprises the monochromatic light solid-state light emitting element of a plurality of different colours, and can provide the monochromatic light of at least two kinds of different colours with switching, for example 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 the plate body 2 via the side 5 of plate body 2, and propagates in plate body 2.Based on total reflection principle, light can be in plate body 2 interior reciprocating motions.The exiting surface 3 of LED light-emitting device is distributed with some salient points 6, salient point 6 is for having a plurality of shape, such as being triangle cone, quadrangular pyramid body, positive tetrahedron, cube etc., this salient point 6 has destroyed original smooth flat, and total reflection can not occur, so when light touches salient point 6, just can penetrate out the LED light-emitting device.
Fig. 2 shows a kind of structure of embodiment bumps 6, be coated with the dyestuff 61,62 of different colours on the not coplanar of salient point 6, 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 be absorbed by dyestuff, and the light identical with this dye colour then can leach this dyestuff.For example, 61 is orchil on salient point 6 left sides, and the right side 62 is weld on the salient point 6, and when light source 1 comprised red-light LED and yellow light LED, when the ruddiness that this red-light LED sends passed through this salient point 6, ruddiness can leach the left side of this salient point 6, and its shooting angle is α
1, the gold-tinted that yellow light LED sends then can't see through the left side of this salient point 6; When the gold-tinted that this yellow light LED sends passed through this salient point 6, gold-tinted can leach the right side of this salient point 6, and its shooting angle is α
2, the ruddiness light that red-light LED sends then can't see through the right side of this salient point 6.Like this, red-light LED and the gold-tinted diode of light source are opened simultaneously, only had the regional A of ruddiness, the observer sees only has red light; At the Mixed Zone of ruddiness and gold-tinted B, what the observer saw is the orange-colored light of ruddiness and yellow light mix; And only having the regional C of gold-tinted, what the observer saw is sodium yellow.
Fig. 3 shows the structure of another embodiment bumps 6, and different from Fig. 2 is before dyestuff 61 and 62, to be coated with fluorescent material 611 and 621.Fluorescent material 611 and 621 is used for the monochromatic light that light source sends is converted into the monochromatic light of another kind of wavelength, and dyestuff 61 and 62 color are respectively the monochromatic color that fluorescent material 611 and 621 inspires.For example, light source 1 comprises blue-ray LED, and fluorescent material 611 is for being converted to blue light the material of ruddiness, and 61 is orchil; Fluorescent material 621 is for being converted to blue light the material of 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 regional A of ruddiness, the observer sees only has red light; At the Mixed Zone of ruddiness and gold-tinted B, what the observer saw is the orange-colored light of ruddiness and yellow light mix; And only having the regional C of gold-tinted, what the observer saw is sodium yellow.
Fig. 4 shows an alternative embodiment of the invention, as shown in Figure 4, the LED light-emitting device that scribbles dyestuff comprises the plate body 2 that light source 1, transparent material are made, plate body 2 is rectangular structure, and this plate body 2 comprises exiting surface 31 in the plate body side, another exiting surface 32, the side 5 between exiting surface 31 and exiting surface 32 between relative with exiting surface 3 and is positioned at some micro-structurals 6 of exiting surface 31 and 32.Preferably, this micro-structural 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, triangle cone, quadrangular pyramid body, positive tetrahedron, cube, half sphere shape etc.By such setting, so that this light-emitting device can be realized double-side, so that the observer can see the content of this light-emitting device at obverse and reverse, and by being set at positive and negative, different micro-structurals distributes, and can be so that the obverse and reverse of this light-emitting device can show different contents.
For light is appeared from micro-structural, and do not spill from other places, can not have the position of micro-structural to plate the high material of one deck reflectivity at panel surface, such as mercury, Al, Ag, Au, Cu etc., form the reflecting layer.
Salient point in above-described embodiment can be made by lithographic plate printing method, namely according to needed literal or pattern form, carries out net-pont design, make egative film, then egative film is printed onto on the surface of exiting surface, at last baking or ultraviolet ray irradiation, thus form salient point.Salient point in above-described embodiment also can form by mould molding.
Concave point in above-described embodiment can carry out semiconductor processing method by effects on surface and realize such as etching, laser engraving, impression etc.So-called engraving method comprises the steps: at first to cover layer protecting film at exiting surface; Secondly, by exposure plate-making, develop, diaphragm that will etching area is removed; At last, add chemical solution in the zone of removing diaphragm, reaching the effect of dissolved corrosion, thereby form concave point.
In addition, those skilled in the art also can do other variation in spirit of the present invention, as long as it does not depart from technique effect of the present invention and all can.The variation that these are done according to spirit of the present invention all should be included within the present invention's scope required for protection.
