Narrow beam angle for SLS and COB spots
The solution: Fresnel lenses. Because of the technical conditions, the beam angle of COB and SL spots is naturally wide. A good focusing was not possible until now. But the angle can easily be narrowed on both series – with lenses.
Thanks to the lenses, the beam angle is remarkably smaller, the light is more focused. For the SLS series, the beam angle is narrowed from 40° to 25°. This way, new possibilities of use show up.
