When the detection signal is changed, the control is not in accordance with the normal signal determination criterion. The single control will immediately control the corresponding electronic switch 4 to switch to the open state to achieve the function of power failure protection.
例如，該等照明元件的正常工作電壓範圍是斯 广〇v時’該正常信號判斷基準就設定為28〇〜鳩的數值 範圍，當該控制單A 70所接收的檢知信號νι數值為 290(V)則為正常工作狀態’如果超出28〇〜_的數值範圍 則立即控制對應的電子開關40進行斷電。 藉此，透過擷取該等檢知信號V1，以及該正常信號判 斷基準的檢測機制，就可以即時掌握點燈異常狀態，並控 制該等電子開關40切換為開路以達到斷電保護的功能。 如圖2所不，以下將更進一步說明本發明照明供電保 7 200938764 濩系統200的第二較佳實施例，該第二較佳實施例與上述 邊第一較佳實施例大致相同，其不同處在於該系統2〇〇還 包含一參考電壓22及二電壓比較器80,該參考電壓22在 實際製造時可經由該供電單元21供應，該等電壓比較器80 是接收該等檢知信號VI與該參考電壓22，並可分別將一呈 見问電位與低電位其中一者狀態的電壓比較結果V2輸入到 該控制單元70，該正常信號判斷基準是採用一與該電壓比 較結果V2做比對的邏輯狀態。For example, when the normal operating voltage range of the lighting elements is 斯广〇v, the normal signal determining reference is set to a value range of 28〇~鸠, and the value of the detecting signal νι received by the control sheet A 70 is 290. (V) is the normal working state 'If the value range of 28〇~_ is exceeded, the corresponding electronic switch 40 is immediately controlled to be powered off.
