Description
本發明涉及電源供應器的發光裝置,特別是一種可以自動選擇控制訊號,不需要使用者進行手動切換的發光裝置及其發光控制方法。 The invention relates to a light-emitting device of a power supply, in particular to a light-emitting device that can automatically select a control signal and does not require a user to manually switch, and a light-emitting control method thereof.
已知有許多安裝於個人電腦主機使用的電源供應器裝設有發光裝置,其中大部份的發光裝置都是使用發光二極體(LED)作為發光元件,為了能夠產生豐富多彩的光線,可以產生多種不同發光顏色的三色發光二極體(RGB LED)或是LED發光條也被應用於電源供應器的發光裝置;另外,為了產生更棒的光影效果,有許多的發光裝置是直接將發光元件裝設在風扇,利用轉動的扇葉產生動態的光影效果,例如已公開的中華民國新型專利證書號M526606號的”發光風扇裝置之組設結構”。 It is known that many power supplies installed in personal computer mainframes are equipped with light-emitting devices.
