Abstract
Provided is a wavelength-conversion member that, when light is emitted from an LED or an LD, minimizes the decrease in light emission intensity over time. A wavelength conversion member characterized in comprising a sintered compact of a pulverulent mixture containing (a) as a glass composition, a glass powder containing an alkali metal element and a polyvalent element, and (b) an inorganic phosphor powder.
Description
Technical field
The present invention relates to the wavelength convert parts that wavelength convert is other wavelength of light light emitting diode (LED:LightEmittingDiode) or laser diode (LD:LaserDiode) etc. sent.
In recent years, the instead light source of future generation of fluorescent lamp and electric filament lamp, from low consumption electric power, small-size light-weight, light quantity regulate be easy to viewpoint, to use LED or LD light source focus on raising. An example as such light source of future generation, for instance have the light source being configured with absorption on the LED of injection blue light from a part for the light of LED the wavelength convert parts being converted into sodium yellow disclosed in patent documentation 1. This light source sends as the white light from the LED blue light penetrated and the synthesis light of the sodium yellow from the injection of wavelength convert parts.
As wavelength convert parts, inorganic phosphor powder is always made to be scattered in the parts obtained in resinous substrates. But, when using these wavelength convert parts, there is resin and deteriorate due to the light from LED, the problem of the easy step-down of brightness of light source. It is especially in the presence of mould resin to deteriorate due to short wavelength's (blueness��ultraviolet) light of the LED heat sent and high energy, the problem that variable color and deformation occur.
Therefore, motion has and is disperseed fixed inorganic fluorophor powder in glass matrix by replacing resin and wavelength convert parts (for example, referring to patent documentation 2 and 3) that the complete inoganic solids that obtains is constituted. These wavelength convert parts have the glass becoming base material and not easily deteriorate, are not susceptible to the feature of the problem of variable color and deformation due to the heat of LED chip and irradiation light.
But, firing and deteriorating, be susceptible to the problem that brightness is deteriorated when above-mentioned wavelength convert parts exist inorganic phosphor powder due to manufacture. Particularly in the purposes such as general lighting, special lighting, owing to requiring high colour rendering, so needing the inorganic phosphor powder using the thermostability such as red or green relatively low, the deterioration that there is inorganic phosphor powder becomes significant tendency. Therefore, motion, by by containing alkali metal in making glass powder form, makes the wavelength convert parts (for example, referring to patent documentation 4) that softening point reduces. These wavelength convert parts are owing to being undertaken manufacturing it is possible to suppress the deterioration of inorganic phosphor powder when firing by firing of relatively low temperature.

Summary of the invention
Invent problem to be solved
But, in glass matrix containing the above-mentioned wavelength convert parts of alkali metal exist luminous intensity easily through time (As time goes on) and the problem that reduces. Further export increase along with light sources such as LED and LD in recent years, luminous intensity through time situation about reducing become notable increasingly.
Therefore, it is an object of the invention to provide when the light of irradiation LED or LD, through time luminous intensity reduce few wavelength convert parts.
For solving the scheme of problem
The wavelength convert parts of the present invention are characterised by: the sintered body comprising mixed-powder, and this mixed-powder contains glass powder and (b) inorganic phosphor powder that (a) contains alkali metal and element of multivalence as glass composition. In the present invention, " element of multivalence " refers to the element of desirable multiple valence mumber.
As it has been described above, when wavelength convert parts containing alkali metal in glass matrix being irradiated the light of LED or LD of height output, exist luminous intensity through time situation about reducing. About detailed reason, present inventor is presumed as follows.
When the glass matrix containing alkali metal in the composition is irradiated exciting light, energy due to exciting light, the outermost electronics of the oxonium ion being present in glass matrix is excited, leave oxonium ion, part basic ion in glass matrix is combined, form paint centre (herein, being subsequently formed room in basic ion disengaging). On the other hand, the hole generated due to electron detachment is moved in glass matrix, and a part is caught by the room formed after basic ion departs from and formed paint centre. It is believed that these paint centre formed in glass matrix become the absorption source of exciting light and fluorescence, thus the luminous intensity of wavelength convert parts reduces.
