Abstract

The aim of the invention is to increase the light efficiency of a lighting fixture by providing a high brightness and the uniform distribution of a light flux inside a working area and to simplify the lighting fixture assembling process. The inventive lighting fixture comprises a body whose internal surface is shaped in the form a segment of sphere and on which light-emitting-diode modules are mounted in such a way that they are grouped and annularly arranged along the body internal surface symmetrically with respect to the center thereof. Inside a group, the light-emitting-diode modules are positioned at unequal distances from the body center and all groups are embodied in such a way that said light-emitting diode modules are internally located in the same manner. The radius of the sphere, which form the body internal surface, ranges from 0.8 to 1.2 m. The lighting fixture also comprises a decorative surface and a transparent cover which is made, for example, of optical polycarbonate and is shaped identically to the shape of the body internal surface. Said body internal surface and the cover can be embodied in the form of an assembly of spherical segments.

Светильник Lamp
Область техникиTechnical field
Изобретение относится к медицинской технике, а именно к хирургическим светильникам.The invention relates to medical equipment, namely to surgical lamps.
Известен светильник, содержащий корпус со светоизлучающими элементами, выполненными в виде матричных светодиодных панелей, прозрачную крышку и светорассеивающую панель (см. патент РФ на полезную модель JVa 27852, МПК F21V 11/00, оп. 20.02.2003г.). Известный светильник достаточно трудоемкий при сборке, так как требуется большое количество светодиодов для получения требуемого уровня освещенности, а также имеет не достаточно высокую световую эффективность.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.
Известен бестеневой осветитель холодного света, содержащий кольцо с элементами освещения в виде нескольких светодиодных модулей, каждый из которых закреплен на штанге, установленной в одном из гнезд кольца на сферическом шарнире, и источник питания (см. патент РФ JSb 2252441, МПК G02B 21/06, оп. 20.05.2005г.).Known shadowless cold light illuminator containing a ring with lighting elements in the form of several LED modules, each of which is mounted on a rod mounted in one of the ring sockets on a spherical hinge, and a power source (see RF patent JSb 2252441, IPC G02B 21/06 , op. May 20, 2005).
Недостатком известного устройства является необходимость юстировки каждого из светодиодных модулей.A disadvantage of the known device is the need to align each of the LED modules.
Наиболее близким по технической сущности к заявляемому изобретению является операционный светильник, содержащий корпус, выполненный из отдельных модулей, механически соединенных между собой, на внутренней поверхности которого закреплены светодиодные модули (заявка на ЕП JVs 1568935, МПК F21S 8/00, F21S 2/00, оп. 31.08.2005г.).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).
Известный операционный светильник имеет высокую световую эффективность, однако он имеет достаточно сложную конструкцию. Задачей, на решение которой направлено заявляемое техническое решение, является упрощение конструкции светильника при сохранении его высокой световой эффективности.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.
Поставленная задача решается следующим образом. Раскрытие изобретенияThe problem is solved as follows. Disclosure of invention
В хирургическом светильнике, содержащем корпус, на внутренней поверхности которого закреплены светодиодные модули, согласно заявляемому изобретению, корпус светильника выполнен цельным, внутренняя поверхность которого выполнена в форме сегмента сферы, а светодиодные модули объединены по меньшей мере в четыре группы, расположенные по кольцу внутренней поверхности корпуса симметрично относительно центра корпуса и имеющие одинаковое внутреннее расположение светодиодных модулей.In a surgical lamp containing a housing, on the inner surface of which LED modules are fixed, according to the claimed invention, 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.
При этом светодиодные модули внутри одной группы расположены на неравных расстояниях от центра корпуса.In this case, the LED modules within one group are located at unequal distances from the center of the housing.
Кроме того, радиус сферы, образующей внутреннюю поверхность корпуса, составляет 0,8 - 1,2м.In addition, the radius of the sphere forming the inner surface of the body is 0.8 - 1.2 m.
Кроме всего, светильник оснащен крышкой, имеющей форму, идентичную форме корпуса светильника, и выполненной, например, из оптического поликарбоната.In addition, 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.
В заявляемом светильнике корпус выполнен цельным, имеющим внутреннюю поверхность в форме сегмента сферы, что упрощает конструкцию светильника. Расположение светодиодных модулей на внутренней поверхности корпуса объединенными по меньшей мере в четыре группы с одинаковым внутренним расположением светодиодных модулей в каждой из них, которые прикреплены к внутренней поверхности корпуса по кольцу симметрично относительно центра корпуса, также упрощает конструкцию светильника и обеспечивает равномерную освещенность операционного поля. Закрепление на внутренней поверхности корпуса светильника светодиодных модулей, объединенных в три группы и менее, обеспечивает недостаточное освещение в условиях затенения во время хирургической операции. Выполнение внутренней поверхности корпуса светильника в форме сегмента сферы позволяет сложить световые потоки отдельных светодиодных модулей, объединенных в группы, оптимизируя световой поток.In the inventive lamp, 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.
Расположение светодиодных модулей внутри каждой группы на различном расстоянии от центра корпуса и расположение групп на внутренней криволинейной поверхности корпуса обеспечивает при сложении световых потоков всех групп высокую однородность распределения света внутри рабочей зоны.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.
Величина радиуса сферы, образующей внутреннюю поверхность корпуса светильника, определена опытным путем, составляет 0,8 — 1,2м. и является оптимальной для сложения световых потоков светодиодных модулей, объединенных в группы, обеспечивая оптимизированный световой поток на операционном столе. Выполнение сферы радиусом менее 0,8м. или более 1,2м. уменьшает величину рабочей зоны и снижает световую эффективность светильника. Крышка, выполненная, например, из оптического поликарбоната, по форме, идентичной форме внутренней поверхности корпуса светильника, характеризуется высоким коэффициентом пропускания видимого света, поддерживает его высокую световую эффективность и исключает загрязнение источников света. Таким образом, перечисленная выше совокупность признаков заявляемого светильника позволяет упростить конструкцию светильника при сохранении его высокой световой эффективности.The radius of the sphere forming the inner surface of the lamp housing, determined empirically, 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. Thus, the above set of features of the claimed lamp allows to simplify the design of the lamp while maintaining its high luminous efficiency.
Наличие отличительных от прототипа существенных признаков позволяет признать заявляемое изобретение новым. Из уровня техники не выявлены технические решения, совпадающие с отличительными признаками заявляемого объекта, поэтому заявляемое устройство соответствует критерию изобретательского уровня.The presence of essential features distinctive from the prototype allows us to recognize the claimed invention as new. The prior art does not reveal technical solutions that match the distinguishing features of the claimed object, therefore, the claimed device meets the criteria of an inventive step.
Пример конкретного выполнения На фиг. 1 изображен светильник, общий вид; на фиг. 2 - расположение светодиодных модулей на внутренней поверхности корпуса светильника; на фиг. 3 - схема сложения световых потоков светодиодных модулей.An example of a specific implementation In FIG. 1 shows a lamp, general view; in FIG. 2 - the location of the LED modules on the inner surface of the lamp housing; in FIG. 3 is a diagram of the addition of light fluxes of LED modules.
Светильник состоит из корпуса 1 , нижней крышки 2, светодиодных модулей 3. Корпус светильника имеет декоративную внешнюю поверхность 4 и внутреннюю поверхность 5, на которой группами 6 установлены светодиодные модули 3. Количество групп 6 светодиодных модулей 3 в зависимости от конкретных потребностей может быть от 4 до 8. Сложение световых потоков светодиодных модулей 3 происходит в рабочей зоне 7, расположенной на расстоянии от 0,7м. до 1,4м. от корпуса 1 , что является оптимальной величиной для хирургических светильников.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.
Во время работы светильника внутри рабочей зоны каждой из группDuring operation of the lamp inside the working area of each of the groups
6, образованных светодиодными модулями 3, создается максимальный уровень освещенности и путем сложения световых потоков всех групп 6 создается общий световой поток в рабочей зоне 7. При этом внутри рабочей зоны каждой из групп 6 сохраняется практически постоянный диаметр светового поля, что очень важно для хирургического светильника, а сложение световых потоков светодиодных модулей 3 различных групп 6 создает высокую однородность распределения света внутри рабочей зоны 7.6 formed by LED modules 3, the maximum level of illumination is created and by adding the light fluxes of all groups 6, a common light flux is created in the working area 7. At the same time, an almost constant diameter of the light field is maintained inside the working area of each group 6, which is very important for a surgical lamp and the addition of the light fluxes of the LED modules 3 of various groups 6 creates a high uniformity of light distribution within the working area 7.
Промышленная применимость Изобретение может быть использовано в медицинской технике. Industrial Applicability The invention can be used in medical technology.
