Title (EN) CYLINDRICAL IRRADIANCE-MAPPING LENS AND ITS APPLICATIONS TO LED SHELF LIGHTING
(FR) LENTILLE CYLINDRIQUE DE REPORT D'ECLAIRAGE ENERGETIQUE ET APPLICATIONS D'ECLAIRAGE D'ETAGERES PAR DEL
Abstract: front page image
(EN)A cylindrical irradiance-redistribution lens is positioned over a line of LEDs, and is shaped to redistribute their light for uniformly illuminating a nearby planar target, such as shelves, signs, or walls. The lens shape is calculated via matching the cumulative lateral flux functions of the line of LEDs with that of the uniformly illuminated planar target. Numerous preferred embodiments are disclosed for a variety of illumination geometries.
(FR)Cette invention concerne un lentille cylindrique de distribution d'éclairage énergétique qui est disposée au-dessus d'une rangée de DEL et dont la forme permet de redistribuer la lumière émise par ces diodes en vue de l'éclairage uniforme d'une cible plane proche telle qu'étagère, panneau de signalisation ou paroi. On détermine la forme de la lentille en mettant en correspondance les fonctions cumulées de flux latéral de la rangée de DEL et celle de la cible plane à éclairage uniforme. Sont décrits de nombreux modes de réalisation préférés pour diverses géométries d'éclairage.
