MIROS design At a glance – the most common design mistakes

Glare caused by projector withdirect scattered light or spill.When the projector is used pro-perly, a special glare-protection louvre reduces this criticaleffect. Glare caused by mirror which isset at too shallow an angle (50°max.). This allows direct viewingof critically high luminance. Light cones do not overlap suf-ficiently. The floor is well lit butthe cones of light do not overlap sufficiently; light cones muststart to overlap at a height of atleast 2 metres. Glare due to scattered light. Light that is reflected by othermirrors, areas of glass or shinysurfaces may result in glare. Excessive irradiation will occur ifmirrors that are too small are used or if insufficient allowance is made forthe fact that the target area of themirror is reduced by tilting it relative to the projector. Multiple irradiation aimed atilluminating a common surfacearea. The configuration shown inthe picture does not allow direct illumination in the area under- neath the reflector.
