    Abstract: A light emitting device includes a package having a recess which includes a bottom surface having corners. The package includes a first electrode, a second electrode, and a resin portion. The first electrode is provided at a first part of the bottom surface. The second electrode is provided at a second part of the bottom surface. The resin portion is provided between the first electrode and the second electrode at a third part of the bottom surface. A protection element is provided on the bottom surface. A light reflective material covers the bottom surface except for an uncovered region to cover the protection element and the corners of the bottom surface and uncovers an uncovering region of the bottom surface. The uncovered region is defined by linear lines and curved lines connecting the linear lines. A light emitting element is provided in the uncovered region on the bottom surface.

    Abstract: A light-emitting module includes a first mounting board having a first surface and a second surface opposite to the first surface. The first mounting board has a recess on the first surface, and the recess has a bottom surface. The first mounting board has an opening passing through the first mounting board from the bottom surface to the second surface. The light-emitting module further includes a second mounting board provided in the recess, a light-emitting element provided on the second mounting board and configured to emit light through the opening, and an elastic cushion provided between the first mounting board and the second mounting board. The light-emitting module also includes a connector. The connector and the opening sandwich a center of the first mounting board when viewed from a direction from the second surface to the first surface.

    Abstract: A light emitting device is provided which includes a light emitting element, a phosphor, and a sealing member. The light emitting element has a light emission peak wavelength in the range not shorter than 400 nm and not longer than 460 nm. The phosphor can be excited by light from the light emitting element, and emit luminescent radiation with a light emission peak wavelength in the range in not shorter than 600 nm and not longer than 700 nm. The sealing member includes a pigment for absorbing a part of the light from the light emitting element. X of the light emission chromaticity of the light emitting device falls within the range of x≧0.600 in the chromaticity coordinates in the CIE 1931 color space chromaticity diagram.
