Patent CA-2427720-A1 (CA)
Title: Light diffusing apparatus
Inventor: KLEINSASSER MELVIN
IPC: F24F7/02
Filed: 2003-05-05
Abstract: A light diffusing apparatus is provided for attachment to an upright vent pipe, for example the type found in poultry barns and the like. The apparatus includes a mounting collar for securement about one end of the vent pipe and a plurality of generally annular baffles supported on the mounting collar substantially co-axially with the mounting collar. The baffles are spaced apart in an axial direction and have varying diameter from one another so that the baffles overlap one another in a radial direction. The configuration of the baffles ensures that light cannot pass through the vent pipe when the light diffusing apparatus is supported thereon.  In particular, overlapping of the baffles in the radial direction thereof while the baffles remain vertically spaced apart permits ventilating air to pass therethrough while blocking light travelling through the vent pipe in an axial direction of the pipe.
