and the control unit is used for correspondingly adjusting the color temperature of each lamp to be controlled in the current time environment according to the duty ratio of the RGB three channels of each lamp to be controlled at the current time.
8. The apparatus of claim 7, wherein the computing unit comprises an acquisition module and a computing module:
the acquisition module is used for acquiring the ambient luminous flux at the position of the lamp through the light sensing unit to obtain current ambient brightness data, and providing the current time corresponding to the acquired ambient brightness data through the clock unit;
the calculation module is used for obtaining the PWM duty ratio of RGB of each lamp at the current moment according to the current environment brightness data acquired beside each lamp and the current moment corresponding to the current environment brightness data, and obtaining the duty ratio of RGB three channels of each lamp at the current moment according to the PWM duty ratio of RGB of each lamp at the current moment.
9. The apparatus of claim 8, wherein the control unit comprises:
the pulse receiving module is used for receiving the pulse of each lamp to be controlled;
the pulse modulation module is used for splitting each received pulse into a plurality of sub-pulses in a pulse width modulation mode;
the pulse distribution module is used for dividing a plurality of sub-pulses into three parts according to the duty ratio of RGB three channels of the lamp to be controlled at the current moment, so that the first part of the sub-pulses drives an R channel in the RGB three channels of the lamp to be controlled, the second part of the sub-pulses drives a G channel in the RGB three channels of the lamp to be controlled, the third part of the sub-pulses drives a B channel in the RGB three channels of the lamp to be controlled, and the color temperature of the lamp to be controlled in the current moment environment is adjusted.
10. A computer-readable storage medium, on which a computer program is stored, which, when being executed by a processor, carries out the steps of the method according to any one of the claims 1 to 6.
