摘要： Provided is a white light source system that reproduces the light-emission properties of sunlight having temperature colors and light-emission spectrum shapes that change over time, said white light source system being used for office and domestic illumination. As a result of the present invention, a white light source system is provided that includes a plurality of white light sources. A relationship formula is fulfilled whereby the absolute value is no more than 0.15 for the difference between P (λ) × V (λ) / P (λmax1) × V (λmax1) and (B (λ) × V (λ)) / B (λmax2) ×V (λmax2), when the light-emission spectrum for each white light source is P (λ), the light-emission spectrum for black body radiation indicating the same color temperature as each white light source is B (λ), the spectrum for spectral luminous efficiency is V (λ), the maximum wavelength for P (λ) × V (λ) is λmax1, and the maximum wavelength for B (λ) × V (λ) is λmax2. The white light source system is characterized by the light-emission properties of the white light emitted from the system continuously changing over time, as a result of changing the mixing ratio for light from a plurality of white light sources.

摘要： A light emitting device and an LED light bulb using white LED light sources have light control and toning functions equivalent to those of an incandescent light bulb. The light emitting device includes a first light source which emits a first white light having a first color temperature and a second light source which emits a second white light having a second color temperature higher than the first color temperature, and emits a mixed white light of the first white light and the second white light. A color temperature of the mixed white light of the first white light and the second white light is lower as an emission intensity of the mixed white light is lower.

摘要： The present invention provides an illuminating light source capable of providing white light which is gentle on the human body and does not contain excessive blue light components, the brightness of the light not decreasing even when lit continuously for a long period of time, and at the same time having high-level color rendering characteristics. According to an embodiment, this white LED includes at least three types of members based on an ultraviolet to violet light emitting LED, a blue phosphor that converts the primary light emitted by the LED to blue light, and a YAG-based phosphor that absorbs some of the secondary light emitted by the blue phosphor and converts the absorbed secondary light to green to yellow light. White light resulting from the mixing of green to yellow light, etc., with blue light is radiated from the white LED. The white light has high-level color rendering characteristics and a high luminous flux maintenance factor, and enables exhibiting of excellent characteristics with countermeasures implemented for problems such as blue-light hazards.
