Abstract

The invention is suitable for the technical field of LED lighting, and provides an LED lamp string and a control chip thereof. The LED control chip comprises a chip address setting module, an addressing module, a luminance generating module and a driving module. The address setting module is electrically connected with the addressing module, the addressing module is electrically connected with theluminance generating module, and the luminance generating module is electrically connected with the driving module. As the first address mode and the second addressing mode are incorporated in the LED control chip, and the addressing mode is determined and addressed according to the external signal, when fast addressing is required, by selecting a second addressing mode to correspondingly searchthe address of the control chip according to the addressing code of the external signal, The address of the LED control chip does not need to be compared with the address of the external signal one byone, the addressing time is effectively shortened, the addressing efficiency is improved, and the problem of the addressing time and the low addressing efficiency of the traditional LED control chipin addressing is solved.

Description

technical field [0001] The invention belongs to the technical field of LED lighting, and in particular relates to an LED lamp string and a control chip thereof. Background technique [0002] When controlling the light emission of the LED light string, the LED light string is usually controlled by the controller to emit light. The LED control chip in the LED light string corresponds to a unique address. The controller can precisely control each LED light string through the address of the LED control chip. The brightness and color of the LED lights change to form the required graphics. At present, when addressing the LED control chip, the address is generally searched from 0. When the address of the LED control chip is consistent with the address contained in the addressing command sent by the controller, the corresponding LED lights will take corresponding actions. (lighting, turning off, brightness change, etc.), however, when the address of the LED control chip is very lar...
