Abstract
A luminaire () comprising identical curved LED Modules (″) in an inner and an outer arrangement of LED Modules. Said LED Module comprising a curved PCB () having a main surface and a number of LEDs () arranged thereon. The LED Module has width W and is curved with its main surface extending in a plane Q. The LED Module extends over a circle with a radius Rc, wherein 200 mm<=Rc<=450 mm, and extends over an angle a over said circle, wherein 36°<=a<=72°. The number of LEDs is in between 3 and 150. Each LED () has a respective doughnut like shaped lens to render the LED during operation to emit a rotational symmetric batwing beam with a maximum intensity Imax of the batwing beam at an angle 13 with 60°<=13<=80° with said optical axis, and a FWHM in the range of 15-30°.
