Description
Overview
A.39 Suspension / Ceiling Controlled Emission limits its emission to 65 degrees, the angle required by standard EN 12464, with UGR below 19. Carlotta de Bevilacqua designed A.39; this range is made in black, silver and white.
Construction
The patent-pending optic system pairs a thin black square-meshed grid with square plano-convex lenses of appropriate beam angle. The inside of the grid is white painted with a high reflection coefficient. The screen is supplied separately.
Specifications
1180 x 45 x 85 mm (suspension module AT19604IN2APP). IP20, 62 W, 4460 lm, 3600K, CRI 80, 220-240 V.
Story
A net cut-off at the required angle
The grid sits over the lenses and lets only the rays inside the required output limits reach them. Rays beyond those limits are recovered and redirected inside the light box when they meet the white surface, or cancelled when they meet the black edge.
Designed with image optics
The convex profile of each lens is designed with image optic techniques. Luminance at 65 degrees and beyond is below 3,000 cd/m2.
