This invention provides a thermal radiation area temperature detection and feedback module for phototherapy equipment and a thermal radiation area radiation dosage control method, which mainly utilizes a non-contact temperature detector to detect the actual dermis layer temperature of the skin area radiated by laser or pulse light of the phototherapy equipment then using a feedback unit to compare the difference between the actual dermis layer temperature and a predetermined temperature and further generate a feedback signal to be transmitted to the control unit of the phototherapy equipment, such that the control unit can adjust the emission power of the laser or pulse light radiation head to achieve a stable laser or pulse light radiation dosage on the dermis layer.本發明係提供一種光療設備之熱照區溫度偵測回饋模組與熱照區照射劑量調控方法,主要係利用一非接觸式溫度偵測裝置,偵測光療設備之雷射或脈衝光所照射皮膚區域之實際真皮層溫度,再以一回饋單元比較該實際真皮層溫度與預設溫度之差異,進而產生一回饋訊號傳送至光療設備之控制單元,使該控制單元可調整雷射或脈衝光照射頭之發射功率,獲致穩定之真皮層雷射或脈衝光照射劑量。1‧‧‧光療設備10‧‧‧熱照區溫度偵測回饋模組12‧‧‧照射頭14‧‧‧控制單元16‧‧‧非接觸式溫度偵測裝置18‧‧‧回饋單元
