Definitions
- the present invention relates to a chromaticity coordinate inspection method of a phosphor dispersion sheet, a method of manufacturing a phosphor dispersion sheet, a method of manufacturing a light conversion member, and a method of manufacturing an LED package, and in particular, individual light conversion members in the phosphor dispersion sheet.
- the chromaticity coordinate inspection method which makes it possible to evaluate the variation in characteristics from the chromaticity coordinates corresponding to the above, a phosphor dispersion sheet manufacturing method to which the inspection method is applied, a light conversion member manufacturing method, and an LED package manufacturing method.
- a material in which an inorganic phosphor is dispersed in glass is known (see, for example, Patent Document 1).
- the light conversion member having such a configuration can utilize the high transmittance of glass, and can efficiently release the heat generated from the LED element to the outside of the light conversion member. Moreover, the damage of the light conversion member (especially phosphor) by light and heat is low, and long-term reliability is obtained.
- light conversion members having similar chromaticity coordinates are obtained by being assigned to a predetermined class. It can be simple.
- seat 50 when the intensity
- the strength of the phosphor dispersion sheet 50 when the strength of the phosphor dispersion sheet 50 is low and it deforms due to its own weight, it is assumed that the frame mold has a transparent holding plate, and the phosphor dispersion sheet 50 is placed on the holding plate. What is necessary is just to make it hold
- the spectrometer 4 measures the spectral data of the transmitted light emitted from the phosphor dispersion sheet 50 when irradiated with the excitation light from the LED light source 3, and a known spectrometer can be used.
- spectroscopic instruments examples include TM series mini-spectrometers manufactured by Hamamatsu Photonics Co., Ltd., C10082CA and C10083CA, and multi-channel spectrometers manufactured by Konica Minolta Co., Ltd.
- “transmitted light” means “transmitted excitation light” in which excitation light is transmitted through the phosphor dispersion sheet 50 without being wavelength-converted, and excitation light is wavelength-converted and emitted from the phosphor dispersion sheet 50.
- the “converted light” is synthesized and refers to light (synthesized light) actually emitted from the surface of the phosphor dispersion sheet 50. Note that both the transmitted excitation light and the converted light are scattered light that scatters on the surface of the phosphor dispersion sheet 50, and therefore, the synthesized light is also obtained as scattered light.
- this spectrometer 4 should just be able to measure the transmitted light radiate
- the chromaticity coordinate calculation unit 5 calculates chromaticity coordinates from the spectral data obtained by the spectrophotometer 4, and the chromaticity coordinates are obtained by performing a predetermined calculation process on the spectral data. Specific contents of the arithmetic processing performed at this time will be described in a chromaticity coordinate inspection method described later.
- the storage unit 6 stores the chromaticity coordinates calculated by the chromaticity coordinate calculation unit 5 and the measured sections of the phosphor dispersion sheet 50 in association with each other, and includes known storage devices such as a hard disk device and a memory. It is done. In addition, when calculating the chromaticity coordinate of LED mentioned later, the chromaticity coordinate of virtual transmitted light, etc. in this memory
- excitation light for exciting the phosphor contained therein is emitted from the LED light source 3 to the phosphor dispersion sheet 50.
- the emitted excitation light is incident from one surface of the phosphor dispersion sheet 50, passes through the phosphor dispersion sheet 50, is scattered, is converted into light, and is emitted from the other surface.
- the transmitted light (the combined light of the transmitted excitation light and the converted light; the alternate long and short dash line in FIG. 1) is measured by the spectrometer 4 to acquire the spectral data of the transmitted light.
- the chromaticity coordinate calculation step in this step is the same operation as the spectral measurement of the phosphor-dispersed sheet described in the first embodiment, except that the spectral data is excitation light data obtained by the LED spectral measurement step. Done by the method.
- the combination optimization process in the present embodiment is based on the chromaticity coordinates obtained in the chromaticity coordinate calculation process of the virtual transmitted light, and the combination that will be the desired transmitted light when actually mounted on the LED chip. It is a step of determining.
- the LED light source and the light conversion member separated from the phosphor dispersion sheet have variations.
