Abstract: A light emitting device includes: a substrate; a first light emitting element and a second light emitting element that are mounted above the substrate; and a heat transfer pattern that is formed on the substrate. A rate of decrease in light output with respect to a temperature increase is greater for the second light emitting element than for the first light emitting element. The second light emitting element is mounted above the substrate via the heat transfer pattern, and the first light emitting element is mounted above the substrate without the heat transfer pattern.

Abstract: A wavelength conversion member includes a substrate, a dichroic mirror layer, an SiO2 layer, a ZnO layer, and a phosphor layer, which are sequentially stacked from the substrate. The dichroic mirror layer reflects at least part of light incident from the above. The phosphor layer includes a plurality of phosphors and ZnO between the phosphors.

Abstract: A light-emitting device includes a board; and light-emitting element arrays connected in parallel and each including light-emitting elements mounted on the board and connected in series. The light-emitting elements in each of the light-emitting element arrays include one or more red LED chips and one or more blue LED chips. Each of the red LED chips on the board is disposed non-successively to any other one of the red LED chips along a Y direction and along an X direction. The Y direction is parallel to a direction along which the red LED chips included in one of the light emitting arrays including the red LED chip are arranged. The X direction is perpendicular to the Y direction.

Abstract: A phosphor layer contains phosphor particles, and satisfies the following relations: y≥0.0623x2+0.2107x+28.789 and y≤−0.1172x2+7.584x+81.148 where x represents the average particle size (μm) of the phosphor particles, and y represents the thickness (μm) of the phosphor layer.
