Definitions

• the invention relates to medical equipment, namely to surgical lamps.
• a known lamp containing a housing with light-emitting elements made in the form of matrix LED panels, a transparent cover and a light-diffusing panel see RF patent for utility model JVa 27852, IPC F21V 11/00, op. 02.20.2003.
• the well-known lamp is quite laborious during assembly, since a large number of LEDs are required to obtain the required level of illumination, and also has not a sufficiently high luminous efficiency.
• a disadvantage of the known device is the need to align each of the LED modules.
• the closest in technical essence to the claimed invention is an operating lamp comprising a housing made of separate modules mechanically interconnected, on the inner surface of which LED modules are mounted (application for EP JVs 1568935, IPC F21S 8/00, F21S 2/00, Op. 31.08.2005).
• the well-known operational lamp has a high luminous efficiency, however, it has a rather complicated structure.
• the task to which the claimed technical solution is directed is to simplify the design of the lamp while maintaining its high luminous efficiency.
• the lamp housing is made integral, the inner surface of which is made in the form of a sphere segment, and the LED modules are combined in at least four groups located along the ring of the inner surface of the housing symmetrically with respect to the center of the housing and having the same internal arrangement of LED modules.
• the LED modules within one group are located at unequal distances from the center of the housing.
• the radius of the sphere forming the inner surface of the body is 0.8 - 1.2 m.
• the lamp is equipped with a cover having a shape identical to the shape of the lamp housing, and made, for example, of optical polycarbonate.
• the housing is made integral, having an inner surface in the form of a segment of a sphere, which simplifies the design of the lamp.
• the location of the LED modules on the inner surface of the housing combined in at least four groups with the same inner location of the LED modules in each of them, which are attached to the inner surface of the housing in a ring symmetrical to the center of the housing, also simplifies the design of the lamp and ensures uniform illumination of the operating field. Fastening on the inner surface of the luminaire housing of the LED modules, combined in three groups or less, provides insufficient lighting in the shade during surgical operations.
• the implementation of the inner surface of the lamp housing in the form of a sphere segment allows you to add the light fluxes of individual LED modules, combined into groups, optimizing the light flux.
• the location of the LED modules within each group at a different distance from the center of the housing and the location of the groups on the inner curved surface of the housing provides a high uniformity of light distribution within the working area when the light fluxes of all groups are combined.
• the radius of the sphere forming the inner surface of the lamp housing is 0.8 - 1.2 m. and is optimal for combining the light fluxes of LED modules in groups, providing an optimized light flux on the operating table.
• Running a sphere with a radius of less than 0.8m. or more than 1.2m. reduces the size of the working area and reduces the luminous efficiency of the lamp.
• a cover made, for example, of optical polycarbonate, in a form identical to the shape of the inner surface of the lamp housing, is characterized by a high transmittance of visible light, maintains its high luminous efficiency and eliminates pollution of light sources.
• FIG. 1 shows a lamp, general view
• FIG. 2 the location of the LED modules on the inner surface of the lamp housing
• FIG. 3 is a diagram of the addition of light fluxes of LED modules.
• the lamp consists of a housing 1, a lower cover 2, LED modules 3.
• the housing of the lamp has a decorative outer surface 4 and an inner surface 5, on which LED modules 3 are installed in groups 6.
• the number of groups 6 of LED modules 3, depending on specific needs, can be from 4 up to 8.
• the addition of light fluxes of LED modules 3 occurs in the working area 7, located at a distance of 0.7 m. up to 1.4m. from housing 1, which is the optimal value for surgical fixtures.
• the invention can be used in medical technology.
