Technical Field

Background
The operating shadowless lamp is a special device which adjusts the angle of the lamp or the angle of a polished reflecting surface into annular illumination, thereby achieving the purpose of forming a shadow or a dead angle formed by the convex and concave structure of an illumination part, becoming a picture with uniform brightness and providing illumination for an operating area. The operating shadowless lamp is designed by utilizing the principle of a multipoint light source effect, namely when a plurality of light sources irradiate an object, light rays of some light sources are shielded by the object and cannot irradiate a receiving surface to generate a shadow, light rays of other light sources can irradiate the shadow area from another angle, so that the shadow of the area is weakened and eliminated, and a shadowless area is finally formed.
Surgical shadowless lamps are important devices essential to illuminate surgical sites and are required to optimally view objects of low contrast at different depths, sizes, in incisions and body cavities. Therefore, in addition to "shadowless", the illumination intensity is required to be uniform and the light quality is required to be good, and the color difference between blood and other tissues and organs of the human body can be well distinguished.
