Abstract:
A pixel-controlled LED light includes a plurality of LED modules and a controller. Each LED module includes at least one LED and a LED drive apparatus. The LED drive apparatus burns an ordinal number according to connection sequence thereof. The controller defines the ordinal number of the LED module as a target number, and sequentially transmits a plurality of light mode data whose number is greater than or equal to the target number to each of the LED modules. Each of the LED drive apparatuses sequentially receives each of the light mode data and counts sequence of the light mode data. If the sequence of the light mode data is equal to the ordinal number of the LED drive apparatus, the LED drive apparatuses identify the light mode data, and after identifying the light mode data, the LED drive apparatuses control the corresponding at least one LED.
