摘要：
This invention relates to an array type high-power ultraviolet light sterilization system, particularly referring to a short-wavelength ultraviolet light sterilization system with a microcontroller as a core and integrating with an automatic optical power control system to achieve an effect of optical power control by performing light detection with infrared light and automatically controlling an ultraviolet light switching mechanism, as well as applying the microcontroller to develop a short-wavelength light-emitting diode that maintains a stable optical power output, and through a power compensation mode and modification of compensation parameter of an automatic optical power control circuit. In the automatic optical power control system, the operation is performed by utilizing the microcontroller. When the optical power of the ultraviolet light diode changes with the temperature, the current of a driving circuit can be automatically adjusted to allow the short-wavelength ultraviolet light diode to maintain stable optical power output at different temperatures and achieve a purpose of temperature compensation.一種陣列式高功率紫外光殺菌系統,尤特指以微控制器為核心之短波長紫外光殺菌系統並整合自動光功率控制系統,以紅外光光偵測且自動控制紫外光開關機制,運用微控制器以開發令短波長發光二極體維持穩定光功率輸出,透過自動光功率控制電路之功率補償方式與補償參數之修改,達成光功率控制之效果,在自動光功率控制系統中,利用微控制器進行運算,當紫外光二極體之光功率隨溫度變化時,可自動調整驅動電路之電流量,令短波長紫外光二極體在不同的溫度下仍能維持穩定的光功率輸出,達到溫度補償之目的,為其特徵者。10‧‧‧微控制器20‧‧‧紅外線動作感測器30‧‧‧儀表放大器40‧‧‧短波長紫外光發光二極體50‧‧‧發光二極體
