目前常見的傳統燈會控制器,大多數是採用PLC可程式控制器做為燈會控制器,其特點有二:1.無線性調光:只能做一些簡單的閃爍及速度上的變化。2.施工複雜:每一組迴路的燈光,其電源線都必須拉回PLC可程式控制器來作控制,如此一來,會增加現場施工配線上的難度。 本論文改善上述缺點並且可適用於LED燈,其特點有三:1.具線性調光的效果:在燈光調變上是採取交流調光技術,而交流調光模組則是採取交流電壓串聯方式,主要是用來改善場地及距離所帶來的壓降問題。2.四線串聯:同時也考量到現場施工的方便性,只要將各交流調光模組串接即可,便能夠實現大範圍的燈光控制。3.燈泡方面:是採用白熾燈或LED燈可交換使用,因全球環保節能意識高漲之下 LED燈將會逐漸取代白熾燈。
The traditional temple fair’s lamp controller (TFLC) was based on PLC controller. With PLC based TFLC had two significant drawback:1. No linear dimming:TFLC can only do some simple flicker and speed changes. 2. Construction is complex: Each set of loops of light must be back to the PLC controller. This will increase the difficulty of construction wiring. This thesis is to improve the above shortcomings. There are three characteristics:1. with linear dimming effect:The AC series dimming technology was utilized in this thesis. 2. four-wire connected in series:With this series construction technology it can decrease the difficulty of construction wiring. 3. enlarging the light source:Conventional TFLC light source can only use tungsten lamp, the LED light source can also use in this project.
