Lighting Systems for the Control of the Processes, Occurring in the Pressurized-water Reactor

Constructon of optical lighting systems with LEDs means the use of non-imaging optical elements with different shapes refractive and reflective surfaces. Well-known calculation methods, which are used for the calculation of spherical and similar to it aspheric optics, are not applicable. By itself, the emitting area of ?? the LED emits according to the law, which is close to Lambertian. Typically, LEDs are already equipped with the primary lens. They are used in lighting units to illuminate the fuel elements which is extremely advantageous when the light output is used as fully as possible. In the study, the technique of a fundamentally new design of the lighting unit. The main element of lighting system will become LED.
