A liquid-cooling method for cooling the LED lights used for minimally invasive surgeries. The LED lights are integrated with the micro camera side by side so that only one pipeline is needed to accommodate the electrical wires and cooling-liquid conduits. The electricity and signal wires provide the path for electrical power required by the micro camera as well as the electronic signals from the micro camera, respectively. The liquid conduits guide the circulating cooling liquid to pass by the bottom surface of the LED substrate and carry the generated heat off the human body and dissipate to the environment.一種針對微創手術之發光二極體燈之液冷散熱方式,其中發光二極體燈與微攝影鏡頭整合於相鄰位置並共用一根管件,該管件至少包含電源線通道與循環冷卻液進出之通道。電源線通道中的電源線及訊號線提供攝影鏡頭之電源及攝影訊號之傳輸線;冷卻液進出通道提供發光二極體燈散熱所需之冷卻液之進出,冷卻液流經發光二極體燈基座底面,將發光二極體燈產生之廢熱移出至人體外部並散出。1‧‧‧LED燈與微攝影鏡頭之整合元件2‧‧‧內含冷卻液流道與電源線通道的長管3‧‧‧冷卻液流入流道4‧‧‧冷卻液流出流道6‧‧‧電源線通道7‧‧‧電源線束10‧‧‧液冷之LED燈與微攝影鏡頭之整合裝置11‧‧‧微攝影鏡頭12‧‧‧LED燈
