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.
Claims15
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 the 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 and a second inner louvre, each having a rearward light obscuring region, wherein the first inner louvre and the second inner louvre are each at least partially located within the outer louvre,
- wherein there is a first engagement means for engaging the outer louvre with the lighting assembly, there is a second engagement means for engaging the first inner louvre with the first lighting arm, and there is a third engagement means for engaging the second inner louvre with the second lighting arm, the louvred lighting fixture having an axis of rotation X-X,
- wherein the first lighting arm, the outer louvre, the first inner louvre, and the second 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, the first inner louvre, and the second inner louvre are rotated about their respective longitudinal axes of rotation, they are also rotated about axis X-X,
- wherein 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,
- wherein the second light emitting device is arranged so that, in use, it directs a beam of light transversely to the longitudinal axis of the second lighting arm,
- wherein 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, and
- wherein the second inner louvre is arranged so that, in use, the second inner louvre can be rotated about axis X-X so that the rearward light obscuring region can be positioned at least partially within the beam of light emitted by the second light emitting device.
