The invention relates to an optical signaling device, in particular, railway signaling device, containing at least one LED light source, an electronic power supply and an electronic loading element arranged in a single body. To extend the service life the temperature of LED light source is maintained particularly low because the body is made of material with very high thermal conductivity, preferably aluminum alloy, has external cooling ribs and forms a cavity closed from all sides. This ensures quick and even distribution of heat produced by LED light source connected to the body and its removal to the environment. Due to the fact that each heat source is adjacent to the outer wall of body of appropriate size, and at least a portion of the outer wall of the body extends between the LED and loading element the absence of heat flow from the loading element to the LED light source is ensured. |
