Surgical shadowless lamp is an essential lighting equipment for the operating room, which is of great help to surgical safety, surgical quality, surgical efficiency, continuous working ability and eye hygiene of the operator. Shadowless lamps are used to illuminate the surgical site for optimal observation of small, low-contrast objects at different depths in the incision and body cavity.

The surgical operator's head, hands, and instruments can cast shadows on the surgical site, so surgical shadowless lamps should be designed to eliminate shadows as much as possible and minimize color distortion. In addition, shadowless lamps need to work continuously for a long time without emitting excessive heat, because excessive heat can make the surgeon uncomfortable and dry out the tissues in the surgical area. Choosing a shadowless surgical lamp will effectively avoid the phenomenon of mixing or shadowing in the process of surgery on the patient, and will not affect the doctor's operation.
