Abstract
The lighting industry has become the bigger and more systemized using the semiconductor LED with each control R(Red), G(Green), B(Blue). The communication standard DMX512(ANSI E1.11) protocol of it basically needs the address which can be distinguished between the lighting terminals. The conventional method has to give the address of the lighting any methods like dip switch, EEROM and PROM. Then the lighting terminal can receive RGB data from DMX512 communication. According to electrical characteristics DMX512 protocol has to the splitter every 32 lighting terminals. If 512 lightings is all connected, maximum 16 splitters are needed. This paper is solved above weakness in DMX512 protocol using serial connection all lighting terminals. Also I developed the intelligent lighting terminal with auto-addressing. This was solved the inconvenience of the address assignment and the usage of the splitter. The developed products is applied and selled the semiconductor lighting terminals using ON-OFF control, dimming control, sequential control and rainbow control.
