摘要： A light emitting device includes: a first white light source which includes N pieces of first white light emitting diodes and emits a first white light; and a second white light source which includes M pieces of second white light emitting diodes and a first resistance element electrically connected in series to the second white light emitting diodes and having a first resistance value, is electrically connected in parallel to the first white light source, and emits a second white light, the light emitting device emitting a mixed white light of the first white light and the second white light. The drive voltage of the first white light source is higher than a drive voltage of the second white light source, and a color temperature of the mixed white light is higher as a total luminous flux of the mixed white light is higher.

摘要： According to one embodiment, a white light source includes a combination of a light emitting diode and phosphors. One of the phosphors is at least a cerium activated yttrium aluminum garnet-based phosphor. There is no light emission spectrum peak at which a ratio of a largest maximum value to a minimum value is greater than 1.9. The largest maximum value is largest among at least one maximum value present in a wavelength range of 400 nm to 500 nm in a light emission spectrum of white light emitted from the white light source. The minimum value is adjacent to the largest maximum value in a longer wavelength side of the light emission spectrum.

摘要： According to one embodiment, there is provided a white light source system including white light sources. An absolute value of a difference between (P(λ)×V(λ))/(P(λmax1)×V(λmax1)) and (B(λ)×V(λ))/(B(λmax2)×V(λmax2)) for each of the white light sources satisfies a relational expression represented by |((P(λ)×V(λ))/(P(λmax1)×V(λmax1))−(B(λ)×V(λ))/(B(λmax2)×V(λmax2))|≤0.15 The white light source system has a light emission characteristic of white light emitted by the system is continuously changed along with an elapse of time by changing a mixing ratio of light beams from the 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. The inner surface of the cavity does not include any surface recessed inwardly.
