Abstract
EL light emitting device includes a cylindrical EL light emitting unit and a columnar power feeding unit. EL light emitting unit is composed such that a cylindrical receiver coil is arranged and connected along an inner circumferential face of the cylindrical EL light emitting element and integrated into a single body by an outer cover member. The power feeding unit is formed in a columnar shape whose diameter is smaller than an inner diameter of EL light emitting unit so that the power feeding unit can be inserted into the cylindrical EL light emitting unit. When the power feeding unit is inserted into EL light emitting unit and the power feeding unit is impressed with an alternating voltage, a high alternating voltage corresponding to the turn rate of both coils is generated in the receiver coil, so that light can be emitted from EL light emitting element.
