Abstract
A louvred lighting fixture comprising a lighting assembly and a louvre assembly. The lighting assembly comprises a lighting arm having a light emitting device. The louvre assembly comprises an outer louvre 19 and an inner louvre. The louvred lighting fixture 1 has an axis of rotation X-X, wherein the lighting arm, the outer louvre and the inner louvre each have a longitudinal axis of rotation that is coaxial with the axis of rotation X-X, so that, in use, the outer louvre and the inner louvre are rotated so that the forward light obscuring region and the rearward light obscuring region can be positioned within the beam of light emitted by the light emitting device.
Claims19
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,
- wherein an inner end of the first lighting arm is attached to the hub on a first 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 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.
A kit of parts for a louvre assembly comprising an outer louvre and an inner louvre,
- wherein the outer louvre has an open cross-sectional profile that is constant along an entire length of the outer louvre,
- wherein the inner louvre has an open cross-sectional profile that extends around an arc of a circle by more than 180° but less than 360° and that is constant along an entire length of the inner louvre, and
- wherein the inner louvre fits within an outer illumination window of the outer louvre.
