摘要 |
Provided are a method, apparatus and system for controlling a light source. The method comprises: acquiring an adjustment signal and determining a dimming item according to the adjustment signal; the dimming item being composed of the value and/or value range of at least one characteristics parameter of a pulse drive signal; converting the adjustment signal into the pulse drive signal indicated by the dimming item; controlling an adjustment switch by means of the pulse drive signal, so as to output a voltage including a chopped wave voltage corresponding to the dimming item, thereby transmitting adjustment information about the colour and/or brightness of the light source by means of the voltage including the chopped wave voltage. The method, apparatus and system can achieve the function of adjusting the colour and/or brightness of the light source.
