ADAPTER, LIGHT SOURCE APPARATUS AND LIGHTING DEVICE

Document Type and Number:

WIPO Patent Application WO/2017/198130

Kind Code:

A1

Abstract:

Disclosed are an adapter, a light source apparatus using the adapter and a lighting device using the adapter. The adapter comprises a main body, an ejecting portion and an operation member. The main body comprises: a power source installation portion, a light source installation portion and conductive circuitry extending from the power source installation portion to the light source installation portion. The ejecting portion can be operatively moved to a stopping position for stopping the power source installation portion from being fitted with a power source module, and a release position for releasing the power source installation portion so same may be fitted with the power source module. The operation member can be operatively moved to a conducting position and to a breaking position on the main body. When the power source installation portion is fitted with the power source module, the ejecting portion is subjected to a blocking force from the power source module and is moved to the release position and is maintained at the release position, and the conductive circuit conducts when the operation member is moved to the conducting position. When the power source installation portion is separated from the power source module, the ejecting portion is moved from the release position to the stopping position, and at the same time, the operation member is driven to move from the conducting position to the breaking position, breaking the conductive circuit. By means of the embodiments of the invention, when there is no usage demand for a lighting device, an ejecting portion is moved to a stopping position, and at the same time, an operation member is driven to move from a conducting position to a breaking position to break the conductive circuit, thereby avoiding electric shock that may be caused by the lighting device being started by an erroneous user operation, thus improving the safety of the lighting device.
