A light fixture has a housing having a depression in which at least one light-emitting diode is received. The light-emitting diode is mounted on a mounting surface and in operation of the light fixture emits light with an initial emission angle of more than 80°. A lens is arranged downstream of the light-emitting diode, having a central focus area and an outer area radially surrounding the focus area. The central focus area is configured and/or arranged in such a way that a part of the light propagating through the focus area is focused in such a way that a final emission angle of the light propagated through the focus area is at least 50° and at most 80°. The outer area of the lens is spaced at least 2 mm from the mounting surface in a vertical direction.
A light fixture, comprising a housing having a depression in which at least one light-emitting diode is received, which is mounted on a mounting surface and which in operation of the light fixture emits light with an initial emission angle of more than 80°, and a lens arranged downstream of the light-emitting diode, having a central focus area and an outer area radially surrounding the focus area, wherein
A lens for a light fixture, comprising an outer area, a central lens area and annular Fresnel steps radially surrounding the central lens area, wherein the lens is configured to focus light penetrating into the lens and propagating through the lens with an initial emission angle of more than 80° in such a way that a final maximum emission angle of the light propagated through the lens is at least 50° and at most 80°.
