    摘要： This lighting apparatus is provided with a blue LED chip having a maximum peak at a wavelength of 420-480 nm and a fluorescent material-containing resin layer disposed on the front of the blue LED chip in the light emission direction. The fluorescent material-containing resin layer is obtained by mixing and dispersing a LuAg fluorescent material, which is represented by the formula Lu 3 Al 5 O 12 : Ce 3+ and in which the Ce activation rate is 2 mol.% or lower relative to Lu, and a double fluoride fluorescent material represented by the formula A 2 (B 1-x Mn x )F 6 (in the formula, A is at least one type of element selected from among the group consisting of Li, Na, K and Cs, B is at least one type of element selected from among the group consisting of Si, Ti, Nb, Ge and Sn, and x is an integer that falls within the range 0.001 ≤ x ≤ 0.1) in a resin. The present invention is capable of achieving a higher sense of brightness, high visibility and a sense of brightness across a wide range under scotopic conditions or mesopic conditions with an emitted light color close to black body radiation.

    摘要： A present embodiment is to provide a phosphor that has favorable temperature characteristics, that can emit yellow light having excellent color rendering properties, and that has high quantum efficiency. The phosphor emits yellow light when excited with light having a luminescence peak in a wavelength range of 250 to 500 nm and has a crystal structure that is substantially identical to the crystal structure of Sr 2 Al 3 Si 7 ON 13 . In the average crystal structure of the phosphor determined by Rietveld analysis, the distance between an atom at coordinates corresponding to the first coordinates of Sr, M, or Ce atoms and an atom at coordinates corresponding to the 14th coordinates of O or N atoms is 2.0 to 2.6 Å in a case in which the crystal structure is analyzed, assuming that the crystal structure belongs to a space group Pna21, and is represented using crystal structure data standardization software STRUCTURE TIDY.
