LUMINAIRE COMPRISING IDENTICAL, CURVED LED MODULES AND LED MODULE SUITABLE FOR SAID LUMINAIRE

摘要

A luminaire (1) comprising identical curved LED Modules (13, 13', 13") in an inner and an outer arrangement of LED Modules. Said LED Module comprising a curved PCB (14) having a main surface and a number of LEDs (15) 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 200mm <= Rc <= 450mm, 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 (15) 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°.
