Surgical shadowless lamps are used to illuminate the surgical site to best observe small, low-contrast objects at different depths in the incision and body cavity. Since the head, hands and instruments of the operator may cause interference shadows on the surgical site, the surgical shadowless lamp should be designed to eliminate shadows as much as possible and minimize color distortion.
In addition, the shadowless lamp must be able to work continuously for a long time without radiating excessive heat, because overheating will make the operator uncomfortable and dry the tissue in the surgical area.
