| titleOfInvention | White light source and white light source system using the same |
| abstract | In a white light source having a light emitting diode having a peak wavelength of 350 nm or more and 420 nm or less and a phosphor layer comprising four or more kinds of phosphors and resins having different peak wavelengths, the emission spectrum of the white light source is the same as that of the white light source. The emission spectrum of black body radiation indicating the color temperature is B (λ), the spectral luminous efficiency spectrum is V (λ), the wavelength at which P (λ) × V (λ) is maximum is λmax1, and B (λ) × When the wavelength at which V (λ) is maximum is λmax2, the relational expression: −0.2 ≦ [(P (λ) × V (λ)) / (P (λmax1) × V (λmax1)) − (B (Λ) × V (λ)) / (B (λmax2) × V (λmax2))] ≦ + 0.2 and the initial lighting of the white light source using the CIE chromaticity diagram and after continuous lighting for 6000 hours The magnitude of the chromaticity change is less than 0.010. Moreover, the mass ratio of the phosphor in the phosphor layer may be 60% by mass or more and 90% by mass or less. According to the above configuration, it is possible to provide a white light source with high long-term reliability that reproduces natural light and suppresses changes in chromaticity. |
