Abstract: A functional control adapter for light generating devices includes a female portion, a male portion, and a control module. The female portion has an inlet body. The inlet body has a housing member having a first contact module. The male portion has an outlet body connected to the inlet body. A second contact module is disposed on the exterior of the outlet body. The control module is located at the inlet body and connected electrically to the first contact module of the female portion and the second contact module of the male portion. The adapter and the light source are joined separately, thus the lighting device can be dismounted or installed with convenience, and individual parts can be replaced as needed for reducing repair cost.
