Abstract
The invention relates to a fluorescent adhesive tape for converting blue light of an LED into white light and a manufacturing method thereof. The fluorescent adhesive tape mainly comprises a light transmission basal layer and an adhesive layer, wherein the adhesive layer is evenly mixed with 10 to 50 weight percent of fluorescent powder; and the fluorescent powder can convert the blue light emitted by the LED into white light. Through the mixing of the fluorescent powder into the adhesive layer, the light transmission basal layer can keep the original physical property without being influenced so as to make the manufacturing of the whole fluorescent adhesive tape greatly simplified.
Description
Technical field:
The present invention relates to a kind of fluorescent adhesive tape, refer to that especially a kind of blue light that photodiode is sent changes into the fluorescent adhesive tape of white light, also relates to the manufacture method of this fluorescent adhesive tape simultaneously.
Background technology:
Photodiode (LED) has been following trend as lighting.Photodiode sends white light, often is that the light emitting diode combined that will send different colours forms, for example red, green, and blue light-emitting diode combination, but such cost is very high, is not inconsistent economic benefit.
After have fluorescent material (phosphor) sneaked in the packing colloid of photodiode, make blue light change into white light.But because this method is also made quite difficulty, cost is not low yet.
At United States Patent (USP) 7,294, in the preceding case of 861 " fluorescent adhesive tape thing (Phosphor tape article) ", then provide a kind of fluorescent adhesive tape that attaches on the LED package face, make blue light that photodiode sent change into and be white light.In this case, be that fluorescent material is sneaked in the polymkeric substance (polymeric binder material) forming a fluorescent layer, and utilize a glue-line to make this fluorescent layer can be attached to the package surface of lumination of light emitting diode.
Though this case is more easy to manufacture and with low cost than prior art, but after the fluorescence branch is sneaked into polymeric material, can have influence on the rerum natura of polymeric material, be increased in two-dimensional directional and extend into the difficulty of film in control, and behind the generate film no matter its fragility and thermal stability etc. all become and can't determine, even some material can't extend into film as two dimension.Especially in the polyethylene terephthalate film (polyethylene terephthalate film) of normal use, will cause the difficulty that extends, and be difficult for making.Simultaneously, the solution of this case will greatly limit the replacement and the selectivity of polymeric material.These problems all remain to be improved.
Summary of the invention:
Technical problem to be solved by this invention is: at above-mentioned the deficiencies in the prior art, provide a kind of fluorescent adhesive tape that makes blue light of LED change into white light, the blue light that this fluorescent adhesive tape can make photodiode send changes into white light; The manufacture method of the greatly easy fluorescent adhesive tape of a kind of manufacturing also is provided simultaneously.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of fluorescent adhesive tape that makes blue light of LED change into white light, comprise a printing opacity basic unit and a glue-line, this glue-line has stickiness, be attached to the bottom surface of this printing opacity basic unit, and be attached on the light-emitting area of a photodiode; Be characterized in: evenly be mixed with weight percent in the described glue-line and be the fluorescent material that 10～50% the blue light that this photodiode is sent changes into white light.
A kind of method of making above-mentioned fluorescent adhesive tape, its step are earlier to be that 10～50% fluorescent material is evenly sneaked in the glue with weight percent, this glue is coated formed a glue-line in the printing opacity basic unit again.
So, fluorescent material is sneaked in the glue-line, make the rerum natura of printing opacity basic unit no longer be affected and can keep original rerum natura, make that the manufacturing of whole fluorescent adhesive tape is greatly simple and easy, simultaneously, the material of printing opacity basic unit has various selectivity.
Below, will technical characterstic of the present invention and function be described in detail according to the embodiment shown in the drawing.

Fig. 2 is the sectional view that fluorescent adhesive tape of the present invention attaches to photodiode.
Fig. 3 is that fluorescent adhesive tape of the present invention is made schema.
Fig. 4 is a schema of making light-emitting device according to the present invention.
Label declaration:
Printing opacity basic unit 1 glue-line 2
Fluorescent material 21 photodiodes 3
Embodiment:
See also Fig. 1, a kind of fluorescent adhesive tape provided by the present invention, the blue light that photodiode is sent change into and are white light, and it is made of a printing opacity basic unit 1 and a glue-line 2.
The material of printing opacity basic unit 1 can be polyethylene terephthalate film (polyethylene terephthalate film, PET), polyethylene film (polyethylene film, PE), pen film (polyethylene N-PHTHALATE film, PEN), triacetate fiber film (Triacetate Cellulose Film, the TAC film) etc., preferably have a good material of light transmission and thermotolerance.Glue-line 2 has stickiness, is attached to the bottom surface of printing opacity basic unit 1, and can be attached on the light-emitting area of a photodiode 3 (referring to Fig. 2); Glue-line 2 coating thicknesss are 20～60 μ m, and its material can be similar colloids such as acryl glue, silica gel, PU glue, rubber or polymeric gel.
Among the present invention, evenly be mixed with weight percent in the glue-line 2 and be 10～50% fluorescent material 21, the blue light that this fluorescent material 21 can make photodiode 3 be sent changes into white light.And fluorescent adhesive tape applicable wavelengths scope of the present invention is: red-500～750nm, Huang-450～700nm and green-450～700nm.
And then referring to Fig. 3, the present invention also provides the manufacture method of above-mentioned fluorescent adhesive tape, and this fluorescent adhesive tape can make the blue light that attaches on the photodiode change into white light.Its step is earlier to be that 10～50% fluorescent material is evenly sneaked in the glue with weight percent, this glue is coated formed a glue-line in the printing opacity basic unit again.Glue-line and printing opacity basic unit are then with aforesaid identical.
Again,, the invention provides a kind of manufacture method of light-emitting device, comprise the steps: referring to Fig. 4
One photodiode is provided, and this photodiode sends blue light;
One fluorescent adhesive tape is provided, and this fluorescent adhesive tape comprises a printing opacity basic unit and a glue-line, evenly is mixed with weight percent in this glue-line and is 10～50% fluorescent material, and the blue light that this fluorescent material can make this photodiode send changes into white light; And
