Publication number: 20090175036Abstract: In some implementations, a light fixture comprises an inner spherical member, a plurality of light emitting elements disposed on the inner spherical member and an outer spherical member substantially encompassing the inner spherical member. In some implementations, the inner and outer spherical members are coupled to a base. In some implementations, the inner and/or outer spherical members are substantially spherical and include a truncated bottom portion that mounts to a base. In some implementations, the outer sphere comprises substantially transparent regions arranged to substantially align with the light elements. In some implementations, the outer sphere is substantially translucent and/or opaque except for the transparent regions.Type: ApplicationFiled: December 22, 2008Publication date: July 9, 2009Inventors: Leni Schwendinger, Courtney Hewitt, Gregory J. Subisak, Raymond C. Rice, Mitchell F. Bruns

Patent number: 6974235Abstract: Prismatic structures having at least certain conventionally linear surfaces thereof configured in a non-linear fashion to control the direction of light exiting said structures, the invention functions to reduce light losses in a luminaire or the like while facilitating the emanation of light from the luminaire at an acceptable viewing angle and with a reduction in glare. Prisms, particularly splitter prisms, configured according to the invention are formed with at least portions of conventionally linear surfaces as arcuate, curvilinear or generally curving segmented surfaces so as to direct light out of the luminaire for useful illumination rather than in a wasteful direction back into the luminaire. Prisms configured according to several embodiments of the invention function to increase light efficiencies either upwardly or downwardly depending on illumination requirements.Type: GrantFiled: October 25, 2002Date of Patent: December 13, 2005Assignee: Acuity Brands, Inc.Inventor: Gregory J. Subisak

Patent number: 6796687Abstract: A bandless seam between reflector and refractor sections of a luminaire globe formed of light-transmissive material and configured to improve optical performance as well as facilitate effective mounting of the reflector and refractor sections together, the invention finds particular utility with suspended luminaires ordinarily requiring a metal band or the like to join said sections into a luminaire globe. Opposing peripheral edge surfaces of the reflector and refractor sections are shaped according to the invention not only to cause even flow of adhesive between said surfaces to adhere said sections to each other but also to reduce brightness at the resulting seam between the sections, thereby improving luminaire appearance and reducing seam brightness and optical glint.Type: GrantFiled: October 25, 2002Date of Patent: September 28, 2004Assignee: Acuity Brands, Inc.Inventors: Joseph C. Hudak, Fred C. Schlichter, Scott L. Posey, Gregory J. Subisak

Patent number: 6786619Abstract: A luminaire globe member formed of light transmissive material and having a reflector section and a refractor section, light from a light source such as a high intensity discharge lamp initially impinging on at least major portions of the reflector section being reflected back into the interior of the globe member by prisms preferably disposed on exterior surfaces of said reflector section, refractive prisms preferably disposed on interior surfaces of the reflector section redirecting said reflected light through a focal point or loci of points directly above the light source, the light thus redirected from the reflector section being incident on surfaces of the refractor section at angles similar to angles of incidence of light rays directly emanating from the light source and directly incident on said refractor section surfaces, thereby to increase light efficiency by virtue of improved light control within the globe member.Type: GrantFiled: October 25, 2002Date of Patent: September 7, 2004Assignee: Acuity Brands, Inc.Inventors: Gregory J. Subisak, Herbert A. Fouke
