When using fiber optics for room lighting it is important to be observant of the utilisation grade and of the spread angle. Fiber optics is incomparable to traditional halogen lighting.
The following points should be observed:
• The spread angle (max. 60 degrees) requires that fiber ends are placed closer to the walls than
halogen spots with parabola, unless you use tiltable fittings.
The distribution of light is very important. The walls should be illuminated in a reasonable height (1.9 – 2.3 metres above the floor, dependent on the height of the room.) The use of optical fittings will reduce the spread angle of the light. This means higher light intensity in a smaller area. The light intensity at the floor is increased, but the light hits the walls lower down, or not at all.
The fitting is an elegant finish on the system; it can be delivered without optics, if the biggest possible spread is wanted, with optics if a higher light intensity at floor level is required, or tiltable for guiding the light onto the walls.
The light level can be adjusted in the following ways:
• Strength of light generator.
The total light efficiency from the system is the same whether many small or a few thicker fiber cables are applied – as long as the poly connector is 100% filled with fiber cables. It is important to remember that a room appears light if the walls are lit!
Many or a few light points? With or without fittings/optics?
• At least 6-7 times as many light outlets are needed as by traditional parabola halogen spots.
optics, while others have fittings with strong optics, if certain areas of the room should be extra lit.
