Abstract
A light emitting device () comprising at least one light source () adapted for, in operation, emitting light (), at least one free-shape refractive lens element () configured to aim light () emitted by the at least one light source () in a first direction towards a surface () to be illuminated by the light emitting device (), the lens element () comprising a first end () adapted for facing in a direction towards the surface () and a second end () adapted for facing in a direction away from the surface (), at least one first TIR element (), the first TIR element () being a collimating TIR element configured to collimate and redirect light () emitted from the at least one light source () in a second direction away from the surface () into light (') propagating parallel and in a downward direction, the first TIR element () comprising a light incoupling surface () and a light outcoupling surface (), the light incoupling surface () being arranged at the second end () of the lens element (), and at least one second TIR element () configured to redirect light (′) redirected by the first TIR element () into light (″) propagating in a direction towards the surface () and comprising an intensity distribution with two intensity peaks at wide angles that are aligned with the intensity peaks of light (′) aimed by the lens element (), the at least one second TIR element () being arranged at the light outcoupling surface () of the first TIR element ().
