Lamp control device for exterior rail vehicle lighting
A light goes on!
At the InnoTrans 2006 Trade Fair, the rail specialist Friedrich Lütze, Weinstadt will be showing the new lamp control device LSG3. As well as standard types of lighting, it is now possible to monitor and control Xenon- Halogen and LED lighting.
The Lütze lamp control device is a compact module that meets all the stipulations of the UIC (International Union of Railways), the StVo (German Road Traffic Law) and the operator, as well as the design requirements for exterior vehicle lighting. The micro-processor controlled module accepts the inputs from the vehicle control system via CANopen or parallel signals. From this a signal image is generated that is then sent via the power drivers directly to the lighting medium. At the same time the LSG3 monitors the outputs for any short-circuits, open-circuits or failure of the lighting medium. This diagnostic information is then sent back to the control system, also via CANopen or parallel signals.
In order to increase the service life of the connected lighting medium, a soft-start is used to switch this on. In addition, the lighting medium’s output power is limited to its rated value by means of PWM (pulse-width modulation). Accurate quartz-control of the blinkers ensures extremely long synchronous blinking in the vehicle interconnection. As the project-specific configuration can be set up locally, adaptations that need to be undertaken at short notice are not a problem. The newly available third generation of the Lütze LSG3 offers connections for up to 49 lighting media.

Background:
Signal and exterior lighting of rail vehicles
The control of rail vehicle signal and exterior lighting presents in many cases a highly complex task. For long-distance inter-city traffic it is the UIC regulations that apply; these contain special stipulations for almost all the networks throughout the rest of Europe. For local commuter systems in Germany, then it is the StVo regulations that have to be observed. The individual wishes of the operators have also to be taken into consideration. In the design of modern rail vehicles the element of exterior lighting is playing an increasingly important role.
