Abstract

The present invention relates to the technical field of smart lighting, in particular to a method for controlling intelligent adjustment of brightness, color and color temperature of lamps. The method periodically stores the total running time of a lamp from the current power-on to the present at each power-on stage by switching on and off; and matches the running time data of the device powered on in different periods with the predetermined logic of dimming, color tuning, or color temperature tuning. Once there is a successful matching, the device enters a mode of automatically cycling dimming, color turning or color temperature tuning. Users may select their favorite brightness, color or color temperature by powering off when lamps automatically switch to the brightness, color or color temperature.

Claims6

Dependent claims

A method for controlling intelligent adjustment of brightness, color and color temperature of lamps, comprising:

acquiring information on device running duration of a current device powered on in different time;
determining a target operating mode of the device based on the information on running duration of the device powered on in different time, wherein when the information on running duration of the device powered on in different time shows the same predetermined number as a dimming logic and consistent predetermined time range with the dimming logic, the target operating mode is a predetermined dimming mode;
when the information on running duration of the device powered on in different time shows the same predetermined number as a color tuning logic and consistent predetermined time range with the color tuning logic, the target operating mode is a predetermined color tuning mode;
and when the information on running duration of the device powered on in different time shows the same predetermined number as a color temperature tuning logic and consistent predetermined time range with the color temperature tuning logic, the target operating mode is a predetermined color temperature tuning mode;
and controlling the operation of the device according to the target operating mode.
