System of the present invention provides a kind of light wave sterilizing system,The light wave degerming mechanism that it includes one to use to issue ultraviolet light as degerming; One to the set mechanism as degerming time and relevant parameter setting; One to the detecting mechanism as detecting environment temperature parameter and previous degerming Hou apart from current time parameter; And one with light wave degerming mechanism,Set mechanism and the processing mechanism of detecting mechanism connection,It is the running to control each mechanism,Light wave degerming mechanism can be started according to the degerming time set by set mechanism,And the parameters for cooperating detecting mechanism to detect are augmented as time when being again started up degerming. Thereby, the light wave sterilizing system of the present invention, the interval time for terminating to use to this starting is used according to previous using the cooperation of detecting mechanism and processing mechanism, active judges that supplement light wave sterilizing system cold Hou enables required warm-up period once again, and reaches the effect of effectively irradiating sterilization light wave dosage enough and saving degerming time.本發明係提供一種光波除菌系統,其包含一用以發出紫外光線作為除菌使用之光波除菌機構;一用以作為除菌時間及相關參數設定之設定機構;一用以作為偵測環境溫度參數及前次除菌後距離目前時間參數之偵測機構;以及一與光波除菌機構、設定機構及偵測機構連接之處理機構,係用以控制各機構之運作,可依據設定機構所設定之除菌時間啟動光波除菌機構,並配合偵測機構所偵測到之各項參數作為再次啟動除菌時之時間增補。藉此,本發明之光波除菌系統,可利用偵測機構與處理機構之配合依據前次使用結束至本次啟動使用之間隔時間,主動判斷補充光波除菌系統冷機後再度啟用所需之暖機時間,而達到有效照射足夠之殺菌光波劑量以及節省除菌時間之功效。
