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 a counting ordinal number according to connection sequence thereof. The controller defines the counting ordinal number of the LED modules which need to be changed their light modes as a target value, and sequentially transmits light mode data whose number is greater than or equal to the target value to each of the LED modules. The LED drive apparatuses sequentially receive the light mode data for counting. If the sequence of the light mode data meets to the counting ordinal number of the LED drive apparatus, the LED drive apparatuses identify the light mode data that are met, and after identifying the light mode data, the LED drive apparatuses control the corresponding at least one LED.

Dependent claims

A pixel-controlled LED light with burnable sequence, comprising:

a plurality of LED modules electrically connected to each other, each LED module comprising:
at least one LED, and
a LED drive apparatus with burning function coupled to the at least one LED and the LED drive apparatus configured to burn a counting ordinal number according to connection sequence of the LED drive apparatus, and
a controller electrically connected to the LED modules, wherein the controller is configured to define the counting ordinal number of the LED modules as a target number for changing a light mode of each of the LED modules, and the controller sequentially transmits light mode data whose number is greater than or equal to the target value to each of the LED modules whose light mode need to be changed,
wherein the LED drive apparatuses are configured to sequentially receive the light mode data for counting if the sequence of the light mode data is equal to the counting ordinal number of the LED drive apparatus, the LED drive apparatuses are configured to identify the light mode data for a corresponding at least one LED, and after identifying the light mode data, the LED drive apparatuses are configured to control the corresponding at least one LED,
wherein the light mode data comprises a start code and an end code, wherein the start code determines the beginning of light mode data and the end code determines the end of the light mode data in order to reduce the amount of data transmitted by the light mode data.

A method of operating a pixel-controlled LED light with burnable sequence, the pixel-controlled LED light comprising a plurality of LED modules and a controller, wherein each LED module comprises at least one LED and a LED drive apparatus with burning function, and the LED drive apparatus is configured to burn a counting ordinal number according to connection sequence of the LED drive apparatus, the method comprising the steps of:

defining, by the controller, the counting ordinal number of the LED modules as a target number for changing a light mode of each of the LED modules, and sequentially transmitting, by the controller, light mode data whose number is greater than or equal to the target value to each of the LED modules whose light mode need to be changed,
sequentially receiving, by the LED drive apparatuses, the light mode data for counting,
identifying, by the LED drive apparatuses, the light mode data for a corresponding at least one LED if the sequence of the light mode data is equal to the counting ordinal number of the LED drive apparatus, and
controlling, by the LED drive apparatuses, the corresponding at least one LED;
wherein the light mode data comprises a start code and an end code, wherein the start code determines the beginning of light mode data and the end code determines the end of the light mode data in order to reduce the amount of data transmitted by the light mode data.
