Abstract: A light source device includes a connector, a light source, a lever member, and a detector. The connector allows the light guide member to be detachably connected thereto. The light source emits light to be incident on the light guide member connected to the connector. The lever member is displaced depending on presence or absence of the connection of the light guide member to the connector. The detector detects the displacement of the lever member and outputs a detection result.

Abstract: A phosphor is a phosphor composed by containing Ce3+ as an emission center in a matrix garnet compound having a garnet structure. Then, in the matrix garnet compound, a part of Ca that composes a crystal of Lu2CaMg2(SiO4)3 is replaced by Mg. Moreover, a light emitting device includes the above-mentioned phosphor. In this way, it is possible to provide a garnet phosphor in which temperature quenching is reduced without largely shifting the light emission peak wavelength from that of a Lu2CaMg2(SiO4)3:Ce3+ phosphor, and to provide a light emitting device using the garnet phosphor.
