Abstract: An illumination device having a number of light sources and a number of light collectors. The light collectors collect light generated by the light sources and convert the light into a source light beam propagating primarily along a primary optical axis. The light sources and the light collectors can be part of a light source module. The light source module can include a cooling module comprising a number of interconnected plane mounting surfaces angled in relation to each other, with the light sources arranged on said plane mounting surfaces. The cooling module can include a first side comprising the mounting surfaces and a second side comprising a number of cooling fins defining a number of radial air channels.

Abstract: The present invention relates to an illumination device comprising a number of light sources and a number light collecting means, where the light collecting means collect light generated by the first light sources and convert the light into a source light beam propagating primarily along a primary optical axis. The light source module comprises a cooling module comprising a number of interconnected plane mounting surfaces angled in relation to each other and where the light sources is arranged on said plane mounting surfaces. The cooling module comprises a first side comprising the mounting surfaces and a second side comprising a number of cooling fins defining a number of radial air channels.

Abstract: A vehicle driving arrangement is provided which has at least two driven wheels, the driving torques of which can be individually regulated by a control device, the control device being connected to a sensor arrangement comprising at least one sensor. Using such a driving arrangement, wheel slip is to be prevented. For that purpose, using a signal of the sensor arrangement, the control device continuously ascertains a maximum torque for each wheel, continuously ascertains the driving torque of each wheel and reduces the driving torque by the appropriate amount when the driving torque ascertained no longer complies with a predetermined limit of difference from the maximum torque.
