4.2.3 Ambient lighting
The Integrus system is practically immune for the effect of ambient lighting. Fluorescent
lamps (with or without electronic ballast or dimming facility), such as TL lamps or energy
saving lamps give no problems with the Integrus system. Also sunlight and artificial lighting
with incandescent or halogen lamps up to 1000 lux give no problems with the Integrus
system. When high levels of artificial lighting with incandescent or halogen lamps, such as
spotlights or stage lighting are applied, you should directly point a radiator at the receivers in
order to ensure reliable transmission. For venues containing large, unscreened windows, you
must plan on using additional radiators. For events taking place in the open air a site test will
be required in order to determine the required amount of radiators. With sufficient radiators
installed, the receivers will work without errors, even in bright sunlight.
4.2.4 Objects, surfaces and reflections
The presence of objects in a conference venue can influence the distribution of infra-red light.
The texture and color of the objects, walls and ceilings also plays an important role. Infra-red
radiation is reflected from almost all surfaces. As is the case with visible light, smooth, bright
or shiny surfaces reflect well. Dark or rough surfaces absorb large proportions of the infra-red
signal (see Figure 4.9). With few exceptions it cannot pass through materials that are opaque
to visible light.
