Formula reel 1 is put to have：Containing phosphor resin 20 and reel 30.
(the containing phosphor resin 20 of rope form)
Rope form seals the light-emitting component for being equipped on luminescent device containing phosphor resin 20.Specifically, containing for rope form is glimmering
Body of light resin 20 has the thermoplastic resin molded for rope form of the i.e. fluorophor of wavelength conversion substance by homodisperse.
As fluorophor, such as oxynitride system fluorophor (Sialon fluorophor etc.) or iii-v chemical combination can be utilized
Object semi-conductor nano particles fluorophor (indium phosphide：InP etc.) or YAG fluorophor.But fluorophor is not limited in above-mentioned
Appearance or other fluorophor (KSF fluorophor or KTF fluorophor etc.) such as nitride phosphor.
In addition, in the present embodiment, fluorophor is although utilized, but other can also be utilized as wavelength conversion substance
Wavelength conversion substance.As long as wavelength conversion substance releases difference with transformation from the wavelength of light that light-emitting component irradiates
The substance of the function of the light of wavelength.
In addition, as the thermoplastic resin of the fluorophor is dispersed with, it is as long as can be used in sealing light-emitting component, then not special
Do not limit, but the temperature preferably at a temperature of less than given crosslinking temperature with thermoplasticity and more than the crosslinking temperature with
The resin of the characteristic of irreversible hardening.
In the present embodiment, the silicone resin with above-mentioned characteristic is utilized as thermoplastic resin.In silicone resin
1 crosslinking is formed, suitably depressurizes and removes molten by BTX (benzenetoluenexylene, benzene-toluene) etc.
The quantity of solvent of semi-solid preparation material after dilution agent, thus to obtain.The silicone resin (is handed over less than aftermentioned given 2 crosslinking temperatures
Join temperature) at a temperature of there is thermoplasticity, the characteristic at the temperature more than 2 crosslinking temperatures with irreversible hardening.
Fig. 2 is that the conceptual viscosity containing the silicone resin included in phosphor resin 20 for representing rope form shown in FIG. 1 is special
The chart of property.As shown in Fig. 2, the silicone resin is in room temperature T0Viscosity under (about 25 DEG C) is viscosity V0(with reference to P in figure0).Viscosity
V0It is the viscosity for the shape containing phosphor resin 20 that can maintain rope form.
By silicone resin from room temperature T0It is heated to silicone resin and forms 2 crosslinked 2 crosslinking temperature T1(about 125 DEG C)
In the case of nearby, the viscosity of silicone resin declines, 2 crosslinking temperature T1The viscosity of tight front becomes viscosity V1(with reference in figure
P1).Viscosity V1It is that silicone resin is molten into flowable viscosity.
Room temperature T0To less than 2 crosslinking temperature T1Temperature region in silicone resin variation be thermal reversibility variation.
Thus, make temperature from 2 crosslinking temperature T1Nearby drop to room temperature T0In the case of, the viscosity of silicone resin increases, in room temperature
T0Under be back to original viscosity V0.Therefore, by room temperature T0To less than 2 crosslinking temperature T1Temperature region in make temperature
Variation, so as in viscosity V0To viscosity V1Between adjust the viscosity of silicone resin repeatedly.
On the other hand, with 2 crosslinking temperature T1In the case that above temperature carrys out heating silicone resin, in silicone resin
It is middle to form 2 crosslinkings and harden.It is false in addition, although the viscosity of silicone resin after hardening can not be substantially defined
It is fixed that the viscosity of silicone resin after hardening is conceptually defined as viscosity V2In the case of, the viscosity of silicone resin is from viscosity V1
Rise to viscosity V2(with reference to P in figure2).Viscosity V2Conceptually define 2 crosslinking temperature when silicone resin forms 2 crosslinkings
Spend T1Under viscosity.
For the silicone resin after 2 crosslinkings, make temperature from 2 crosslinking temperature T1In the case of rising or declining,
Although 2 crosslinking temperature T1Under viscosity and the physical property of elasticity modulus etc. can change (polymer characteristics), but compared to 2
Silicone resin before secondary crosslinking, viscosity and elasticity modulus but relatively increase the (P in figure3, for convenience's sake, will remember
It carries to maintain viscosity V2Situation).
In addition, so-called 2 times are crosslinked, refer to the cross-linking reaction etc. caused by the reaction catalyst different from during such as synthesis
So that hardening further develops, refer to due to temperature to occur as described above the state of reversible viscosity change.
In rope form is containing phosphor resin 20, various fluorescence are included according to the optical characteristics of the needs of luminescent device
Body, although the concentration (containing ratio) of adjustable fluorophor, but if using the silicone resin, as long as the then shape before 2 crosslinkings
State just can adjust its viscosity repeatedly.For this purpose, as described later, the uniform rope form of dispersity of fluorophor can be obtained
Containing phosphor resin 20.
According to rope form containing phosphor resin 20, due to can be so that fluorophor be scattered in the state of silicone resin and protects
Pipe, therefore numerous and diverse degree of the individually existing operation of keeping powdery fluorescent body and fluid resin can be eliminated.
