Abstract

With the development of specific light environment design, people are no longer satisfied with the simple lighting needs of the light source in the traditional sense, and begin to pursue ideal vision in complex light environments. The creation of shadowless spaces has been widely used in various fields, such as medical treatment, photography, dynamic capture, etc. While enjoying the convenience brought by the shadowless space, people are also exploring the most optimized shadowless space design. This article proposes two design methods to achieve shadowless space. One is based on the design concept of traditional shadowless lamps. Light is evenly irradiated to the target object from different directions. By setting the number and position of the light source in the space, shadowless areas are produced within. The second is based on the semi-light principle in the integrating sphere to realize the shadowless space. The reflectivity of the inner surface of the spherical cavity is extremely high. The light emitted by the light source is reflected by the spherical cavity multiple times, and finally evolved into uniform illumination in the space. Diffuse reflection reaches the shadowless space. Based on these two ideas, we proposed two optical design systems and simulated these two systems with Tracepro.
