Smart Design Of Freeform Micro Optical Elements For Thin Direct Lit Lpr 69 article, page 64: direct lit led luminaires consist of led arrays. in order to achieve homogenous light distribution a diffuser sheet is placed at a certain height above the led array. usually the distance between the leds and the diffuser has to be greater than the distance between the leds on the array. to overcome this limitation, additional optical elements like freeform lenses are. In this study, we present a smart design concept for extremely thin free form (ff) micro optical elements (moes) for uniform illumination in direct lit led luminaire systems with a large distance.
Smart Design Of Freeform Micro Optical Elements For Thin Direct Lit In this study, we present a smart design concept for extremely thin free form (ff) micro optical elements (moes) for uniform illumination in direct lit led luminaire systems with a large distance to height ratio (dhr). a design example for a ff moe with a height of only 50 µm that allows for a dhr value of more than 3 is presented. in particular, it is also shown that the arrangement of the. In this study, we present a smart design concept for extremely thin free form (ff) micro optical elements (moes) for uniform illumination in direct lit led luminaire systems with a large distance. For this demand we have designed very thin freeform optical elements with a maximal height of 75 μm that allow to maintain a uniform illumination in direct lit applications using an led array with a comparably large distance between the individual leds. the presented design concept in addition emphasizes the use of cost effective manufacturing. In this study, we present a smart design concept for extremely thin free form (ff) micro optical elements (moes) for uniform illumination in direct lit led luminaire systems with a large distance.
