Principle of shadowless lamp in operating room

In fact, a shadowless lamp can't be a shadowless lamp. It just brightens the umbra and makes it inconspicuous. Arrange high-brightness lamps in a circle on the lamp board to synthesize a large-area light source. In this way, the light can shine on the operating table from different angles, which ensures the sufficient brightness of the surgical field of vision and will not produce obvious shadows, so it is called shadowless lamp.

The surgical shadowless lamp usually consists of one or more lamp holders, which are fixed on the cantilever and can move vertically or circularly. The cantilever is usually connected to a fixed connector and can rotate around it.

The shadowless lamp adopts aseptic handle or aseptic hoop (crankshaft) for flexible positioning, and has automatic braking and parking functions to control its positioning, so as to keep proper space in and around the job site. The shadowless lamp can be placed on the fixed point of the ceiling or wall, or on the track of the ceiling.
