Abstract
A smart lighting device includes a light source module, an image projection module and an ambient light sensing module. The image projection module is pivoted to the light source module, and the ambient light sensing module is electrically connected to the light source module and the image projection module. The ambient light sensing module is configured to sense a brightness value of ambient light. Brightness values of the light source module and the image projection module are adjusted according to the brightness value of the ambient light sensed by the ambient light sensing module. A control method for a smart lighting device is also provided.
