Publication number: 20140268692Abstract: An indirect troffer. Embodiments of the present invention provide a troffer-style fixture that is particularly well-suited for use with solid state light sources, such as LEDs. The troffer comprises light bars mounted proximate to a back reflector. A back reflector defines a reflective interior surface of the lighting troffer. To facilitate thermal dissipation, the light bar can act as a heat sink. A portion of the heat sink is exposed to the ambient room environment while another portion functions as a mount surface for the light sources that faces the back reflector. One or more light sources disposed along the light bar mount surface emit light into an interior cavity where it can be mixed and/or shaped prior to emission. In some embodiments, one or more lens plates extend from the light bar out to the back reflector.Type: ApplicationFiled: March 14, 2013Publication date: September 18, 2014Inventors: Mark Edmond, Dong Lu, Paul Pickard

Patent number: 8833964Abstract: The invention relates to an elongated luminous element (1) having a plurality of approximately point-shaped light sources (2) disposed along a line and having light diffusion means (3) deflecting at least one part of the light rays (12) sent out by the light sources (2) in a desired direction. The light diffusion means (3) are disposed lateral to the main emitting direction of the light sources. The elongated luminous element (1) is particularly suitable for installation in a light box (13) for advertising or demonstration purposes. The light box has a transparent or partially transparent front side (7) and a reflective back side (8). The elongated luminous element (1) or a plurality thereof is or are applied to at least one of the side areas (11, 14), such that the light rays (12) emitted by the light sources (2) and deflected by the light diffusing means (3) are aimed between or on the back side (8) and/or the front side (7) of the light box (13).Type: GrantFiled: September 15, 2010Date of Patent: September 16, 2014Assignee: Tridonic Jennersdorf GmbHInventors: Jure Maglica, Christian Derkits

Patent number: 8807783Abstract: A housing once included a high intensity discharge (HID) light source, lens, and fixture chamber between the housing and lens. The housing is retrofit to exclude a routinely functioning HID light source and exclude at least a portion of the HID lens. The housing is made to include at least a first support for at least one light emitting diode (LED) light source and an LED diode lighting fixture chamber. A second support is affixed at least to the first support and is positioned at least in part outside the LED fixture chamber. The LED light source is mounted to the second support outside the LED fixture chamber. At least one LED light source lens is mounted to provide a lens for the LED light source, also outside the LED lighting fixture chamber. The LED light source is thereby substantially free of exposure to the temperature effects.Type: GrantFiled: December 16, 2011Date of Patent: August 19, 2014Assignee: LED Industries, Inc.Inventors: James Willis Schupple, Joseph Brian Henrie

Patent number: 8807795Abstract: An LED lighting device at least comprises a base made of metal materials; a substrate which is disposed on a surface of the base and has one electrode and at least one LED chip; and an insulation sheet which is disposed between the base and the substrate. The insulation sheet and the substrate satisfy the correlations L2+2×T?L1+2×Cr, W2+2×T?W1+2×Cr and Cr?1.6 mm. By controlling the dimension of the insulation sheet, a creepage distance between the electrode and the base can be increased, so as to solve the safety problem of lighting devices without increasing manufacturing costs.Type: GrantFiled: August 20, 2012Date of Patent: August 19, 2014Assignee: Genius Electronic Optical Co., Ltd.Inventors: Hui-Ju Hsu, Hong-Ping Liu, Yen-Wei Ho
