[0003] However, doctors must be able to accurately distinguish the outline and color of the lesion during surgery, which requires high-level lighting. Therefore, additional lighting equipment is needed in addition to the surgical shadowless lamp. However, most of the additional lighting equipment in the current technology can be adjusted by the doctor according to his needs, which cannot make the additional lighting equipment reach its optimal state and achieve the best use effect.
