Adapter, light source device and illuminating device

A light source device, comprising:

• a light-emitting apparatus;
• and
• an adapter comprising a light source mounting part that is matched with the light-emitting apparatus, wherein the adapter comprises:
• a main body including:
• an outer wall forming an inner cavity;
• a power supply mounting part disposed on the outer wall and used for being matched with the power supply module;
• a light source mounting part disposed on the outer wall, arranged oppositely to the power supply mounting part, and used for being matched with the light-emitting apparatus;
• and
• a conducting wire disposed in the inner cavity, and configured to be capable of being turned on and turned off, and used for transmitting electrical power outputted by the power supply module to the light-emitting apparatus when the power supply mounting part is matched with the power supply module and the light source mounting part is matched with the light-emitting apparatus, wherein the conducting wire is configured to be electrically connected with the light-emitting apparatus;
• an ejector pin movably connected to the main body, in which the ejector pin is operationally moved to a blocking position for preventing the power supply mounting part from being matched with the power supply module and a release position for releasing the power supply mounting part to be matched with the power supply module;
• and
• an operating member movably connected with the main body and the ejector pin, in which the operating member is operationally moved on the main body to an ‘on’ position and an ‘off’ position;
• when the operating member is at the ‘on’ position, the operating member is locked to the inner cavity;
• when the operating member is at the ‘off’ position, the operating member is unlocked from the inner cavity;
• when the power supply mounting part is matched with the power supply module, the ejector pin is moved to the release position under a resisting force of the power supply module and is maintained at the release position, and the operating member is moved to the ‘on’ position to turn on the conducting wire;
• and when the power supply mounting part is separated from the power supply module, the ejector pin is moved from the release position to the blocking position, and meanwhile, drives the operating member to move from the ‘on’ position to the ‘off’ position to disconnect the conducting wire.

An illuminating device, comprising:

• a light-emitting apparatus;
• a power supply module;
• and
• an adapter comprising a light source mounting part that is matched with the light-emitting apparatus, wherein the adapter comprises:
• a main body including:
• an outer wall forming an inner cavity;
• a power supply mounting part disposed on the outer wall and used for being matched with the power supply module, wherein the power supply mounting part in the adapter is matched with the power supply module;
• a light source mounting part disposed on the outer wall, arranged oppositely to the power supply mounting part, and used for being matched with the light-emitting apparatus;
• and
• a conducting wire disposed in the inner cavity, and configured to be capable of being turned on and turned off, and used for transmitting electrical power outputted by the power supply module to the light-emitting apparatus when the power supply mounting part is matched with the power supply module and the light source mounting part is matched with the light-emitting apparatus, wherein the conducting wire is configured to be electrically connected with both the light-emitting apparatus and the power supply module;
• an ejector pin movably connected to the main body, in which the ejector pin is operationally moved to a blocking position for preventing the power supply mounting part from being matched with the power supply module and a release position for releasing the power supply mounting part to be matched with the power supply module;
• and
• an operating member movably connected with the main body and the ejector pin, in which the operating member is operationally moved on the main body to an ‘on’ position and an ‘off’ position;
• when the operating member is at the ‘on’ position, the operating member is locked to the inner cavity;
• when the operating member is at the ‘off’ position, the operating member is unlocked from the inner cavity;
• when the power supply mounting part is matched with the power supply module, the ejector pin is moved to the release position under a resisting force of the power supply module and is maintained at the release position, and the operating member is moved to the ‘on’ position to turn on the conducting wire;
• and when the power supply mounting part is separated from the power supply module, the ejector pin is moved from the release position to the blocking position, and meanwhile, drives the operating member to move from the ‘on’ position to the ‘off’ position to disconnect the conducting wire.
