摘要：
The utility model relates to lighting engineering, namely to lighting devices based on LEDs with different color of radiation, providing the creation of a local light zone of the desired color, in particular to surgical multi-color lamps for illuminating the operating field in operating rooms. A surgical polychrome lamp contains a light source made in the form located on a common base of LEDs with different colors of radiation, as well as a hub made in the form of an optically transparent ma terial, the refractive index of which exceeds the refractive index of air, of a continuous volumetric body having an input base, the geometric dimensions of which correspond to the geometric dimensions of the base of the light source, the output base and the side surface, while the light source is placed near the input base of the concentrator, and the side surface of the concentrator has an expanding in the direction from the input base to the output base, a shape that provides full internal reflection of light rays, pada boiling surface on the hub side. According to a utility model, the source is made in the form of a polychromic LED matrix containing groups of LEDs located on its base that differ in the color of radiation, each of which is made in the form of an LED bar containing a chain of series-connected LEDs of the same color, mounted on the base with the formation of a column of LED matrix, In this direction, from left to right, on the base of the matrix, a column formed by orange LEDs is sequentially placed, a column blue LED column, a column formed by red LEDs, a column formed by green LEDs, a column formed by blue LEDs, a column formed by lemon LEDs. The technical result achieved by using the inventive device is to achieve uniform luminosity of a surgical polychrome lamp, providing the creation of a local light zone of a given color of radiation with high color uniformity. 4 ill.Полезная модель относится к светотехнике, а именно к осветительным устройствам на основе
