Pot plant color controlled LED night-light and control method

The invention discloses a pot plant color controlled LED night-light and a control method. The LED night-light comprises a color detection module, a color classification module, a color display control module and an LED module which are sequentially connected with one another, wherein the color detection module is further connected with the LED module; through a color sensor, the color detection module acquires and judges the color information of leaves and flowers of a pot plant under the white background light emitted by the LED module; the color classification module classifies the acquired color information of the leaves and flowers of the pot plant; the color display control module controls the lighting color of the LED module to be displayed according to one color or a combination of several colors confirmed by the color classification module. Therefore, not only can the space utilization rate and the integral aesthetic value be improved, but also a color atmosphere that LED light is merged with the colors of the leaves and flowers of the pot plant can be obtained, and the life spice is promoted.
