Abstract: There is provided a photocatalytic reactor including a reaction chamber. The reaction chamber includes a first set of fins, a second set of fins, a photo-catalyst disposed upon at least one face of each fin, and a light source arranged to illuminate at least a portion of the photo-catalyst disposed on each fin. Each of the first set of fins is arranged such that a line extending from a base of the fin through a tip of the fin is directed to a first convergence point, and each of the second set of fins is arranged such that a line extending from a base of the fin through a tip of the fin is directed to a second convergence point. The first convergence point is different to the second convergence point, and both the first convergence point and the second convergence point are offset relative to a position of the light source.

Abstract: There is provided a photocatalytic reactor including reaction chamber arranged to receive an airflow including one or more airborne contaminants. The reaction chamber includes a first inner surface, a second inner surface, a photo-catalyst for photocatalytic degradation of one or more of the contaminants disposed upon both the first inner surface and the second inner surface, and a light source arranged to illuminate at least a portion of the photo-catalyst disposed on the first inner surface and the second inner surface. The first inner surface and the second inner surface have distinct parabolic arc-shaped profiles and the profile of the first inner surface is a mirror image of the profile of the second inner surface. The first inner surface and the second inner surface may be consecutive.

Abstract: A lighting device includes a support and an arm which is mountable on the support in a selected orientation for movement relative thereto. The arm has a channel extending at least partially along the length of the arm. A light source is mounted on the arm. A first electrical connector is mounted on the support, and a second electrical connector is mounted on the arm. The second electrical connector is detachably electrically connected to the first electrical connector, and is moveable along the channel with lengthwise movement of the arm relative to the support.
