       The most widely used field of shadowless lamps is the medical field, which is commonly used in operating rooms. The biggest feature of shadowless lamps is "shadowless". Through clever design, the illuminated objects can be "not formed by the shadow of light" to block the line of sight. To give a simple example, take people as the reference object and the sun as the light source. When a person stands under the sun, a shadow will be formed on the side of the person facing away from the sun in the opposite direction to the sun, which is what people call a shadow. Like the astronomical wonders of solar eclipse, lunar eclipse, etc., it is also a similar phenomenon.

      The principle of the shadowless lamp is to "dilute the shadow" by adding a light source around the irradiated object (person). This is the principle of shadowless lamps.

The emergence of shadowless lamps is to facilitate doctors to perform operations on patients. In addition to being used in the medical field, it is also relatively common in reality, such as street lamps with multiple light sources, large indoor chandeliers, etc., all of which are similar in principle. Reduce the shadows formed after light exposure, and play the role of omnidirectional lighting.

Theoretically, light travels in a straight line. After hitting an object, it will be blocked, reflected or refracted by the object. Taking the human body as an example, the light will be blocked by the human body, but some of the light will also be reflected. Multiple shadowless light sets will be configured in multiple directions to achieve better effects, as is the case with some stage lights.
