The invention provides a kindergarten integrated classroom scene type self-adaptive lighting control device. A control unit acquires color temperature and illumination, scene images and human body induction signals of test points of each functional area on the basis of a light color sensing unit, an image acquisition unit and a human body detection unit; based on a trained scene detector, a current lighting scene is recognized according to the characteristics of images, human body characteristics, current time and the like, various combinations of LED string driving currents in a dimmable lamp are evaluated by establishing a dimming lighting distribution table and a light color scoring function, the combination of the driving current values is optimized through a multi-objective optimization algorithm, and finally, an optimization result is transmitted to a driver for dimming. Scoring value adjustment can be performed according to the current activity scene in a classroom so that the optimized illumination co
