Abstract:
To provide a light-emitting device capable of being used in a wide temperature range. To provide a light-emitting device capable of being used in a low-temperature environment and a high-temperature environment. The light-emitting device includes a light-emitting panel, a secondary battery, a circuit, and a sealing structure. The light-emitting panel includes a light-emitting element. The light-emitting element can emit light with power supplied from the secondary battery. The circuit includes an antenna and can charge the secondary battery wirelessly. The light-emitting panel, the secondary battery, and the circuit are provided in the sealing structure. The sealing structure includes a portion through which light emitted from the light-emitting element passes.
