PROBLEM TO BE SOLVED: To provide a light-emitting device which suppresses external irradiation with laser light.SOLUTION: A light-emitting device 20 includes a drive circuit 24 for supplying a drive current to a laser light source 22, a power supply cable 26 for supplying drive power to the drive circuit 24, a first connector 32, and a second connector 34, and is configured to form a propagation path for propagating laser light from the laser light source 22. The power supply cable 26 includes, in the way thereof, a pair of terminals by a first connector 32 and a second connector 34 being connected and disconnected mutually. By connecting the first connector 32 and second connector 34, the pair of terminals of the power supply cable 26 are connected to each other, thus constituting a supply path for supplying the drive power to the drive circuit 24. By disconnecting the first and second connectors 32, 34, the pair of terminals of the power supply cable 26 are disconnected from each other, thus blocking the supply path for supplying the drive power to the drive circuit 24.SELECTED DRAWING: Figure 1

    【課題】レーザー光が外部に照射されるのを抑制する発光装置を提供する。【解決手段】レーザー光源22に駆動電流を供給する駆動回路24と、駆動回路24に駆動電力を供給する給電ケーブル26と、第1コネクタ部32と、第2コネクタ部34を備え、レーザー光源22からのレーザー光を伝搬する伝搬路が形成されるように構成された発光装置20である。給電ケーブル26は、その途中に相互に接続又は分離される第1コネクタ部32と第2コネクタ部34による一対の端子を含み、第1コネクタ部32と第2コネクタ部34とを接続することで給電ケーブル26の一対の端子が相互に接続されて駆動回路24に駆動電力を供給する供給路が構成され、接続を解除することで給電ケーブル26の一対の端子が相互に分離されて駆動回路24に駆動電力を供給する供給路が遮断される。【選択図】図1
