What is the principle of the shadowless lamp in the operating room?
The larger the area that utilizes the luminous object, the smaller the umbra
The principle of “shadowless lamp” is based on the principle that the larger the area of the luminous object, the smaller the umbra. That is, using a large-area light source to emit light at different angles, reduce the “umbra”, and reduce color distortion to a minimum, so as to ensure that the surgical field of view has sufficient brightness.
