US 6,208,073 B1 · Smart light emitting diode cluster and system

Abstract

A smart light emitting diode cluster and system includes a central processing unit (CPU) and a plurality of LED cluster strings, each comprising a plurality of LED cluster connected in series. Each LED cluster includes an LED drive circuit and a plurality of LEDs. The CPU receives external input image signal, and then desired control signal and image data are sent to the LED cluster strings by appropriate processing. The control signal is used to switch the LEDs in the cluster to generate desired image and related color variation. The control signal and image data are transferred to the next LED cluster by the present LED drive circuit. In this manner, the control signal and image data are progressively transferred from the first to the last cluster so that a whole image with color variation can be displayed by all the LEDs in the system.
