[0086] An LED light-emitting device was produced under the following conditions.

[0087] Using a twin-screw extruder, K 2 (Si 0.97 mn 0.03 )F 6 Kneading 0.5kg of the powder in 4.5kg of transparent polypropylene pellets, obtained K 2 (Si 0.97 mn 0.03 )F 6 The content of the powder is 10% by mass containing K 2 (Si 0.97 mn 0.03 )F 6 polypropylene pellets.

[0088] Next, use the obtained K 2 (Si 0.97 mn 0.03 )F 6 The polypropylene pellets were molded with a 20t horizontal injection molding machine to obtain a ring-shaped red-colored adjusting part with an inner diameter of 90 mm, an outer diameter of 96 mm, and a thickness of 10 mm.

[0089] In addition, a polycarbonate resin with a particle size D50 value of 50 μm in a content of 3 to 10% by mass was produced. 3 al 5 o 12: Ce powder kneaded pellets were used as a raw material for injection molding to obtain a disk-shaped yellow wavelength conversion member with a thickness of 2 mm and a diameter of 100 mm.

Abstract

Disclosed is an adjustment component that: includes a complex fluoride fluorophore represented by A2(M1-xMnx)F6 (in the formula: M is at least one type of tetravalent element selected from Si, Ti, Zr, Hf, Ge, and Sn; A is at least one type of alkali metal selected from Li, Na, K, Rb, and Cs and including at least Na and / or K; and x is from 0.001 to 0.3); and adjusts the chromaticity and / or color rendering index of illumination light by absorbing light having a wavelength of from 420 nm to 490 nm inclusive, and emitting light including a red wavelength component.

Description

technical field [0001] The present invention relates to an adjustment member for improving the chromaticity and color rendering of illumination light of a light-emitting device, and a light-emitting device using the same. Background technique [0002] Light emitting diodes are among the most efficient light sources available today. Among them, white light-emitting diodes are rapidly expanding the market as a new-generation light source to replace incandescent light bulbs, fluorescent lamps, CCFL (Cold Cathode Fluorescent Lamp) backlights, and halogen lamps. As one of the components to realize white LED (Light Emitting Diode), LED light emitting device ( LED lighting) has been practical. [0003] Among them, quasi-white LED devices using blue LEDs and yellow phosphors, which have become mainstream at present, are known as Y 3 al 5 o 12 : Ce, (Y, Gd) 3 (Al, Ga) 5 o 12 : Ce, (Y, Gd) 3 al 5 o 12 : Ce, Tb 3 al 5 o 12 : Ce, CaGa 2 S 4 : Eu, (Sr, Ca, Ba) 2 SiO 4 :...
