Main controller for LED lighting systems and layout design thereof on PCB

Abstract

The invention provides a main controller for LED lighting systems. The use range of lamps is expanded from an LED display screen to the inside and outside walls of buildings with arbitrary shapes. Themain controller has excellent performance and can be applied to a wide range of scenarios. The main controller comprises a controller, and a decoding chip, an SRAM memory, a network card chip and a network transformer which are connected with the controller. A video signal is decoded by the decoding chip and then input to the controller. The controller saves the video image data in a video to theSRAM memory, synchronously reads the video image data stored in the SRAM memory, and forwards the video image data through the network card chip. The network card chip transmits the data signal to the network transformer in the form of differential signal. The network transformer is used for signal amplification and isolation protection. The invention further provides a layout design of the maincontroller for LED lighting systems on a PCB.

Description

technical field [0001] The invention relates to the technical field of lighting control systems, in particular to a main controller of an LED lighting system and its layout design on a PCB. Background technique [0002] Urban lighting has blossomed everywhere in China. Buildings and landscapes express the emotions that buildings or landscapes convey to people at night through the artistic lighting design of lighting, or brand positioning, advertising, different light colors, and different lighting. Design performance reflects a kind of image positioning of the building, the owner unit, or the government unit; it stems from the designer's control of aesthetics. On the one hand, he understands the beauty of architecture, and on the other hand, he is familiar with the beauty of lighting. The beauty of the landscape shows its texture at night and the beauty that sunlight cannot shape during the day, but the shaping of these beauty is inseparable from the development and progress...

[0002] Urban lighting has blossomed everywhere in China. Buildings and landscapes express the emotions that buildings or landscapes convey to people at night through the artistic lighting design of lighting, or brand positioning, advertising, different light colors, and different lighting. Design performance reflects a kind of image positioning of the building, the owner unit, or the government unit; it stems from the designer's control of aesthetics. On the one hand, he understands the beauty of architecture, and on the other hand, he is familiar with the beauty of lighting. The beauty of the landscape shows its texture at night and the beauty that sunlight cannot shape during the day, but the shaping of these beauty is inseparable from the development and progress of modern lighting technology, and it also puts forward higher requirements for LED lighting systems. Now Most of the LED lighting systems can only project video onto the display-type LEDs, and their performance can no longer meet the current user needs.
