[0002] The hole-type shadowless lamp is a lighting device designed for medical surgery and examination. Its main goal is to provide high-quality, bright and uniform lighting to reduce shadows during surgery and provide good visibility required by doctors. Traditional surgical lights often create shadows in the surgical area, which brings troubles to surgical operations. The hole-type shadowless lamp is usually composed of one or more high-brightness light sources (such as xenon lamps, LED lamps, etc.) and a set of special focusing systems. The focusing system consists of reflectors, which are precisely designed and arranged to focus light from the light source to the surgical area and provide bright and uniform lighting effects. Through proper optical focusing, the hole-type shadowless lamp can minimize the interference of shadows and provide the high-quality lighting required by doctors.
