## 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.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

The method for controlling intelligent adjustment of brightness, color and color temperature of lamps according to claim 1, wherein the predetermined dimming mode is a PWM dimming mode in which the device is PWM dimmed in a cycle of from low brightness to high brightness and then from high brightness to low brightness.

### Claim 3 (depends on 1)

The method for controlling intelligent adjustment of brightness, color and color temperature of lamps according to claim 1, wherein the predetermined color tuning mode is a three-channel PWM color tuning mode in which a RGB three-channel PWM duty cycle is cycled from low to high, and then from high to low.

### Claim 4 (depends on 1)

The method for controlling intelligent adjustment of brightness, color and color temperature of lamps according to claim 1, wherein the color temperature tuning mode is a mode, in which the color temperature of the device is PWM adjusted in a cycle of from low color temperature to high color temperature and then from high color temperature to low color temperature.

### Claim 5 (depends on 2)

The method for controlling intelligent adjustment of brightness, color and color temperature of lamps according to claim 2, further comprising: storing PWM values in real time until the device exits the target operating mode before power off when the device is powered off and then powered on, and locking the PWM values as last PWM values stored by the device before the last power-off.

### Claim 6 (depends on 1)

The method for controlling intelligent adjustment of brightness, color and color temperature of lamps according to claim 1, further comprising: periodically storing once the current booting running duration of the device at a predetermined time interval, wherein finally, the current power-on running duration of the device is equal to that stored last time of current power-on.
