HIGH PERFORMANCE LIGHTING LOUVERS AND LUMINAIRES

摘要

Lighting louvers formed by transverse and longitudinal blades improve theperformance of indirect ambient light luminaires by increasing light output,widening the output of the luminaire's maximum intensity light, or both. Theselighting louvers include at least one of the following features: non-symmetrically shaped apertures, wider apertures over (or under) theluminaire's lamp (s), longitudinal blades of shorter height nearest the lamps,and longitudinal blades having differently curved longitudinal sides. Each ofthese features contributes to improved luminaire performance.
