Description

Предлагаемое изобретение касаетс  осветительного устройства к киноаппарату или иным проекционным приборам.The present invention relates to a lighting device for a movie camera or other projection devices.

Изображенна  на чертеже оптическа  система состоит из остова 1, на котором , с целью уменьшени  нагревани  проектируемого предмета, укреплена линза 2, одна сторона (задн  ) коей покрыта зеркальной амальгамой, при чем источник света 6 помещен не по оси оптической системы конденсатора 4, 5, а сверху, и ось отражающей линзь расположена под углом к оптической оси конденсатора 4, 5. Дл  утилизации лучей, идущих от источника света 6 по другую его сторону, со стороны, противоположной отражающей линзе 2, помещена втора  отражающа  линза 3, покрыта  отражающим слоем с задней стороны и направл юща  лучи на первую линзу 2 и затем по оптической оси конденсатора 4, 5 на кадровое окошко. Направление луча света в конденсатор 4,5 достигаетс  соответствующим поворотом линзы 2 вокруг ее оси. Таким образом, свет, полностью попада  на линзу 2, отражаетс  ею на собирательные линзы 4 и 5 с пониженным тепловьш эффектом, так как больша  часть тепла уходитThe optical system shown in the drawing consists of the core 1, on which, in order to reduce the heating of the projected object, the lens 2 is fixed, one side (rear) of which is covered with a mirror amalgam, and the light source 6 is placed not along the axis of the optical system of the capacitor 4, 5, and on top, and the axis of the reflecting lens is located at an angle to the optical axis of the capacitor 4, 5. To utilize the rays coming from the light source 6 on its other side, on the side opposite to the reflecting lens 2, a second reflecting lens 3 is placed, covered with a backing layer and a guide beam to the first lens 2 and then along the optical axis of the capacitor 4, 5 to the personnel window. The direction of the light beam to the capacitor 4.5 is achieved by a corresponding rotation of the lens 2 around its axis. Thus, the light completely falling on the lens 2 is reflected by it to the collective lenses 4 and 5 with a reduced heat effect, since most of the heat is lost

вверх и только ничтожное количество его передаетс  линзой 2.upward and only a tiny amount is transmitted by lens 2.

Все составные части оптической системы прикреплены к соответствующим стойкам 8 и 10 при помощи винтов 9.All components of the optical system are attached to the respective racks 8 and 10 with screws 9.

Предмет патента.The subject of the patent.

1.Осветительное устройство к кинематографическому аппарату и иным проекционным приборам, характеризующеес  тем, что, с целью уменьшени  нагревани  проектируемого предмета,источник света б помещен выше оптической оси конденсатора 5, 4, и дл  направлени  пучка световых лучей по оптической оси последнего применена в качестве отражател  дво ковыпукла  линза 2 с нанесенным на ее задней стороне отражающим слоем.1. A lighting device for a cinematographic apparatus and other projection devices, characterized in that, in order to reduce the heating of the projected object, the light source b is placed above the optical axis of the capacitor 5, 4, and for directing the beam of light rays along the optical axis of the latter, it is used as a reflector Two lens caps 2 with a reflective layer deposited on its back side.

2.В охарактеризованном в п. 1 устройстве применение дл  направлени  на отражатель 2 лучей источника б света, идущих в сторону, противоположную отражателю 2, подобного же отражател  3, состо щего из двоЛ овыпуклой линзы, покрытой отражающим слоем с задней стороны.2. In the device described in paragraph 1, the application for directing the reflector 2 beams of the light source b, going in the direction opposite to the reflector 2, is similar to the reflector 3, consisting of a double convex lens, covered with a reflective layer on the back side.
