14. A louvred lighting fixture comprising:
a lighting assembly and a louvre assembly,
wherein the lighting assembly comprises a hub, a first lighting arm having a first light emitting device, and a second lighting arm having a second light emitting device,
wherein an inner end of the first lighting arm is attached to the hub on a first side of the hub, and an inner end of the second lighting arm is attached to the hub on a second side of the hub, wherein the first side of the hub is located on an opposite side of the hub to the second side of the hub,
wherein the louvre assembly comprises an outer louvre having a forward light obscuring region and a first inner louvre having a rearward light obscuring region,
wherein the outer louvre is provided with a rotational engagement means at each end, the first lighting arm is provided with a rotational engagement means at its outer end and the second lighting arm is provided with a rotational engagement means at its outer end, wherein the rotational engagement means at one end of the outer louvre is engaged with the rotational engagement means at the outer end of the first lighting arm and the rotational engagement means at the other end of the outer louvre is engaged with the rotational engagement means at the outer end of the second lighting arm,
wherein there is a first engagement means for engaging the outer louvre with the lighting assembly and there is a second engagement means for engaging the first inner louvre with the first lighting arm, the louvred lighting fixture having an axis of rotation X-X,
wherein the first lighting arm, the outer louvre and the first inner louvre each have a longitudinal axis of rotation that is coaxial with the axis of rotation X-X, so that, in use, when the first lighting arm, the outer louvre and the first inner louvre are rotated about their respective longitudinal axes of rotation, they are also rotated about axis X-X,
the first light emitting device is arranged so that, in use, it directs a beam of light transversely to the longitudinal axis of the first lighting arm, and
the outer louvre and the first inner louvre are arranged so that, in use, the outer louvre and the first inner louvre can be rotated about axis X-X so that the forward light obscuring region and the rearward light obscuring region can be positioned at least partially within the beam of light emitted by the first light emitting device.
