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 control. 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.

Surgical shadowless lamps are generally composed of single or multiple lamp caps, which are fixed on a cantilever and can move vertically or cyclically. The cantilever is usually connected to a fixed coupler and can rotate around it. The shadowless lamp adopts a sterilizable handle or a sterile hoop (curved track) for flexible positioning, and has automatic brake and stop functions to control its positioning. It maintains a suitable space on and around the surgical site. The fixed device of the shadowless lamp can be installed on the fixed point on the ceiling or the wall, and can also be installed on the track of the ceiling.
For shadowless lamps installed on the ceiling, one or more transformers should be installed in the remote control box on the ceiling or wall to convert the input power supply voltage into the low voltage required by most light bulbs. Most shadowless lamps have a dimming controller, and some products can also adjust the range of the light field to reduce the light around the surgical site (reflections and flashes from bed sheets, gauze, or instruments can make the eyes uncomfortable).
