Abstract

FIELD: transport; external lights. SUBSTANCE: device has housing 1 and light source with luminous element 2. Parts 3 and 4 of light beam concentrator are connected to form ellipsoid with focal distance F. Light source 2 is installed in one of focal points of concentrator. Focon 5 is placed opposite to light source coaxially with concentrator. Input end face of focon is arranged at a distance OA less than OF from point O of ellipsoid. Narrow output end face of focon 5 is made flush with outer surface of vehicle. EFFECT: enlarged operating capabilities. 1 dwg

Description

Изобретение относится к транспортной светотехнике, а именно к устройствам внешнего освещения транспортных средств. The invention relates to vehicle lighting, and in particular to devices for external lighting of vehicles.

Задача изобретения упрощение конструкции устройства. На фиг. показана принципиальная свеооптическая и электро-механическая схема устройства для освещения транспортного средства. The objective of the invention is to simplify the design of the device. In FIG. A basic optical optical and electro-mechanical diagram of a device for lighting a vehicle is shown.

Устройство для освещения транспортного средства включает корпус 1, источник света с телом накала 2. Части 3 и 4 концентратора светового потока соединены между собой с образованием эллипсоида с фокусным расстоянием F. В одном из фокусов концентратора установлен источник света 2. Напротив источника света соосно с концентратором установлен фокон 5, при этом входной торец фокона отстоит от точки О эллипсоида на расстояние ОA, меньшее ОF. Узкий выходной торец фокона 5 заделан заподлицо с наружной поверхностью 6 объекта. Части концентратора соединены между собой посредством крепежа 7. A device for lighting a vehicle includes a housing 1, a light source with a filament body 2. Parts 3 and 4 of the light flux concentrator are interconnected to form an ellipsoid with a focal length F. A light source 2 is installed in one of the focuses of the concentrator. The light source is opposite to the concentrator focon 5 is installed, while the input end of the focon is spaced from the point O of the ellipsoid by a distance OA less than ОF. The narrow output end face of the focal plane 5 is flush mounted with the outer surface 6 of the object. Parts of the hub are interconnected by means of fasteners 7.

Устройство работает следующим образом. The device operates as follows.

В режимах движения, не связанных с использованием освещения, источник света 2 выключен. При необходимости источник света 2 включается, световой поток концентрируется посредством отражения, входит в широкий торец фокона 5 и выходит наружу через его узкий торец. Для того, чтобы фокальное пятно полностью захватывалось широким торцом световода, введено соотношение размеров ОA меньше ОF. При этом освещенность на выходе фокона определяется соотношением

Figure 00000002

где Ц коэффициент концентрации;
D1 площадь входного торца фокона;
D2 площадь выходного торца фокона.In motion modes not related to the use of lighting, light source 2 is turned off. If necessary, the light source 2 is turned on, the luminous flux is concentrated by reflection, enters the wide end of the focal plane 5 and exits through its narrow end. In order for the focal spot to be completely captured by the wide end of the fiber, an OA size ratio of less than OF is introduced. In this case, the illumination at the output of the focon is determined by the ratio
Figure 00000002

where C is the concentration coefficient;
D 1 the area of the input end of the focon;
D 2 the area of the output end of the focon.

При подборе указанных площадей и материала для изготовления фокона коэффициент концентрации может достигать величины 1200. When selecting these areas and material for the manufacture of focone, the concentration coefficient can reach a value of 1200.

Таким образом, в предлагаемом устройстве для освещения транспортного средства при его очень простой конструкции обеспечивается значительная яркость. Thus, in the proposed device for lighting a vehicle with its very simple design provides significant brightness.

Устройство может быть широко использовано в авиастроении и автомобилестроении. В любом случае простота и надежность конструкции устройства, его малый вес и габариты повлекут за собой повышение надежности всего объекта в целом, а также улучшение дизайнерских свойств объекта, что немаловажно особенно в автомобилестроении. The device can be widely used in aircraft and automotive industries. In any case, the simplicity and reliability of the design of the device, its low weight and dimensions will entail an increase in the reliability of the entire object as a whole, as well as an improvement in the design properties of the object, which is important especially in the automotive industry.
