The spotlight falls on Rottne’s improved LED lighting.
The new LED lamps used are not just significantly better – they are also dimmable when necessary and positioned so that they facilitate work and driving in the dark. The focus was previously on many lamps. But now Rottne has focussed on wanting them in the right place.
A typical forwarder or harvester features up to 20 lamps. The aim was LED lighting with a balanced and comfortable light that illuminates over a long distance, but which is also good close up, and that does not dazzle the operator. The wrong lamps in the wrong place result in glare, which dazzles instead of giving an illuminated work area. Rottne use four to five different types of LED lamps. A big advantage of dimmable LED is the fact you can adjust the light yourself to reduce reflections from the headboard or load that dazzles. In combination with the headboard lighting, the work area by the wagon is illuminated well.
Many lamps remain in the same fixed positions, but at another angle to produce the best lighting. In other parts of the machine, Rottne has chosen to mix long and close range lighting that produces an optimal overall picture. Furthermore, Rottne has developed unique headboard lighting, modified the bunk lighting and has switched to dimmable work lighting on the forwarder cab which, among others, means the operator is not dazzled by the work lighting reflecting on the headboard.
Behind the new lighting lies many hours of research, simulation and test operations to find the optimal angle, colour temperature and strength of a lamp. Different lamps were simulated in varying environments, including fictitious forests, to find the optimal placement of the lighting points and the strength. Simulations have been performed using virtual forestry machines where Hella has calculated the exact angles of how the lights are to be mounted. LEDs are standard on all machine models. During a transitional period all newly manufactured Rottne machines that have LED lamps will be fitted with the new lighting. The headboard lighting is an option found on all of Rottne’s forwarders.
