Abstract

A light emitting diode lighting unit has longitudinal and transverse axes and comprises a base 12 extending along the longitudinal axis. A partial diffuser 20 has diffusion bands and clear bands each extending along the longitudinal axis of the lighting unit arranged in an alternating pattern across at least a part of the transverse axis of the lighting unit. A plurality of LEDs 14A, B, C are located along the longitudinal axis of the lighting unit such that respective transverse positions of at least a subset of the LEDs are different to the transverse positions of respective neighbouring LEDs.
