Abstract:
A method for controlling distribution of light from a light transmissive globe member of a luminaire having a light source disposed within the globe member, the light source being located within the globe member at a position level with, essentially above or essentially below certain first portions thereof through which light passes for illumination of a space exteriorly of the globe member, light emanating directly from the light source onto at least portions of said first portions of the globe member having a first pattern of angles of incidence thereon, comprising the step of redirecting at least a portion of light incident on at least certain second portions of the globe member level with, essentially located above or essentially located below the light source back into the interior of the globe member to form a second pattern of angles of incidence onto said first portions of the globe member that is similar to the first pattern, at least major portions of the light passing from the globe member being more efficiently controlled and distributed from the globe member wherein the redirected light is caused to pass through a point or loci of points located above the light source.
