LED tubular lighting device

A light emitting diode, LED, tubular lighting device arranged to provide device light, the LED tubular lighting device comprising:

• an elongated hollow tubular member having a first end and a second end, the elongated hollow tubular member comprising a light exit surface (5) extending at least in part between the first end and the second end;
• a plurality of LEDs, each of which is configured to, in operation, emit light, the plurality of LEDs comprising at least a plurality of first LEDs, wherein each of the first LEDs is configured to emit violet light having a dominant peak wavelength in the range 380 nm-420 nm, and a plurality of second LEDs, wherein each of the second LEDs is configured to emit ultraviolet light having a dominant peak wavelength in the range 100 nm-380 nm;
• and
• an elongated carrier arranged within the elongated hollow tubular member, wherein the plurality of LEDs are arranged in at least one succession on the elongated carrier such that at least some of the violet light emitted by the plurality of first LEDs and at least some of the ultraviolet light emitted by the plurality of second LEDs is emitted from the LED tubular lighting device via the light exit surface as the device light, wherein the plurality of LEDs are arranged in the at least one succession such that a distance between at least some consecutive LEDs in the at least one succession varies over the at least one succession while a distance between consecutive first LEDs in the at least one succession is constant over the at least one succession.
