Power LED Pointer

The adjacent sketch shows the structure of a PowerLED pointer. The light of a 40mil PowerLED with approx. 1W electrical power is efficiently coupled into a short piece of polymer fiber. The homogeneously mixed light emerges from the fiber end face and is projected via a lens onto the surface to be illuminated. By means of a small slide glued to the end surface of the polymer fiber, an image can be projected enlarged.

The optical properties of the imaging system depend on the following parameters:

  • diameter of the fiber end face: realized LED pointers with fiber diameters from 1mm to 3mm,
  • the focal length of the imaging lens: lenses with 30mm and 15mm are available for the lens holder used,
  • the distance to the surface to be illuminated.
We can vary these parameters according to customer requirements.
