Abstract

The disclosed embodiments relate to a luminaire (100) comprising an array of LEDs (120). The array of LEDs (120) comprises LEDs chosen from the group of blue LED green LED red LED yellow LED amber LED cyan LED and white LED. The luminaire (100) further comprises a reflecting tube (140) and said array of LEDs (100) is arranged in an entrance aperture (142) of said reflecting tube (140). At least one light source (160) is arranged circumferentially around the reflecting tube (140). The at least one light source (160) comprises at least one LED chosen from the group of deep blue LEDs royal blue LEDs deep red LEDs and UV LEDs. An optical component (170) is arranged to transmit light emitted from the at least one light source (160) into light emitted from the array of LEDs (120).
