    摘要： An illumination apparatus includes a light source(4) having a light emitting surface(14), and an optical element(16) which has a shape rotationally symmetrical with respect to an axis line and which transmits the light of the light source. The optical element includes a through-hole(18) provided along the axis line, an entrance surface(19) which faces the light emitting surface and in which the through-hole is open, an exit surface(20) extending from the outer circumferential edge of the entrance surface, and a total reflection surface(21) which connects the distal edge of the exit surface and the inner circumferential edge of the entrance surface to define the through-hole. The total reflection surface is configured to totally reflect the light of the light source that has entered the optical element from the entrance surface.

    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： An optical element according to an embodiment is formed from a material transparent to visible light and has a rotationally symmetrical shape with respect to the central axis. A cavity containing no transparent material is provided inside the optical element. The inner surface of the cavity has a shape in which a boundary line of the cavity along which a plane including the central axis intersects the inner surface includes a curve portion expanding toward the outside of the optical element. In addition, when an origin is set in the cavity, a clockwise direction around the origin along the boundary line is set as a positive direction, a first tangent vector is set at a first point on the boundary line, and a second tangent vector is set at a second point adjacent to the first point in the positive direction, an angle defined by the second tangent vector with respect to the first tangent vector with the clockwise direction being a positive direction is not less than 0°. The inner surface of the cavity does not include any surface recessed inwardly.

    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.
