Abstract

Изобретение касается оптического сигнального устройства, в частности железнодорожного сигнала по меньшей мере с одним светодиодным источником света, электроникой питания и электрическим нагрузочным элементом, которые расположены на одном корпусе. Для повышения срока службы температура светодиодного источника света удерживается особенно низкой, так как корпус изготавливается из очень хорошо теплопроводящего материала, предпочтительно из алюминиевого сплава, снаружи снабжен ребрами охлаждения и образует окруженное со всех сторон полое пространство. Таким образом, тепло, происходящее от светодиодного источника света, термически проводяще соединенного с корпусом и, равным образом, от нагрузочного элемента термически проводяще соединенного с корпусом и равномерно распределяется и отводится в окружающую среду. Так как каждый источник тепла граничит с соответствующе большой наружной стенкой корпуса и по меньшей мере одна часть наружной стенки корпуса простирается между светодиодом и нагрузочным элементом, предотвращается тепловой поток от нагрузочного элемента к светодиодному источнику света.The invention relates to an optical signaling device, in particular a rail signal with at least one LED light source, power electronics and an electrical load element, which are located on the same housing. To increase the service life, the temperature of the LED light source is kept especially low, since the casing is made of a very good thermally conductive material, preferably aluminum alloy, is provided with cooling fins on the outside and forms a hollow space surrounded on all sides. Thus, the heat from the LED light source is thermally conductively connected to the housing and, equally, from the load element is thermally conductively connected to the housing and is evenly distributed and removed to the environment. Since each heat source is bordered by a correspondingly large outer wall of the housing and at least one part of the outer wall of the housing extends between the LED and the load element, heat flow from the load element to the LED light source is prevented.
