Light-emitting sealing body and light source device

The light-emitting sealing body includes: a housing in which a discharge gas is accommodated, the housing having a first opening through which first light enters along a first optical axis and a second opening through which second light exits along a second optical axis; a first window that hermetically seals the first opening; a second window that hermetically seals the second opening; and a first electrode and a second electrode. The housing is formed of a light-blocking material that does not transmit the first light and the second light. An internal space is defined by the housing, the first window portion, and the second window portion, and the internal space is filled with a discharge gas. The first opening and the second opening are disposed such that the first optical axis and the second optical axis intersect each other. 发光密封体包括：收纳放电气体的箱体，在该箱体形成有第一开口和第二开口，第一光沿着第一光轴经第一开口入射，第二光沿着第二光轴经第二开口出射；将第一开口气密地密封的第一窗部；将第二开口气密地密封的第二窗部；及第一电极和第二电极。箱体由不使第一光和第二光透过的遮光性材料形成。由箱体、第一窗部和第二窗部界定内部空间，内部空间充满放电气体。第一开口和第二开口以第一光轴与第
