20080315116 | Optical UV lamp-on indicator - An observable optical lamp status display system is provided for an ultraviolet irradiation lamp concealed from view. An external lamp status display panel that is within the field of view of an observer registers the operating status of each ultraviolet light irradiation lamp in an array of irradiation lamps. A separate fiberoptic lamp status display filament extends between each ultraviolet radiation lamps and the display panel. The lamp status display filament has a first end terminated in optical communication with the ultraviolet lamp and an opposite end that terminates at an optical sensor in the lamp status display panel. An observer can determine whether or not a lamp is operating simply by observing the output of the optical sensor in the display panel for each lamp operated. | 12-25-2008 |

20120162990 | LAYERED STRUCTURE FOR USE WITH HIGH POWER LIGHT EMITTING DIODE SYSTEMS - A layered structure for use with a high power light emitting diode system comprises an electrically insulating intermediate layer interconnecting a top layer and a bottom layer. The top layer, the intermediate layer, and the bottom layer form an at least semi-flexible elongate member having a longitudinal axis and a plurality of positions spaced along the longitudinal axis. The at least semi-flexible elongate member is bendable laterally proximate the plurality of positions spaced along the longitudinal axis to a radius of at least 6 inches, twistable relative to its longitudinal axis up to 10 degrees per inch, and bendable to conform to localized heat sink surface flatness variations having a radius of at least 1 inch. The top layer is pre-populated with electrical components for high wattage, the electrical components including at least one high wattage light emitting diode at least 1.0 Watt per 0.8 inch squared. | 06-28-2012 |

20110070780 | Rotationally adjustable electrical connector assembly - An electrical connector assembly that includes an adjustment collar and a body having an interior volume. The collar defines a passage that is in communication with the interior volume of the body when the collar is engaged with the body. The collar can be rotated relative to the body and can also be fixed to the body with a locking member. The adjustment collar has a helical thread that engages an electrical connector. Wiring extending through the body can be conductively engaged with the electrical connector. The engagement between the collar and the body allows the rotational position of the electrical connector relative to the body to be easily adjusted and then fixed in place by rotation and the subsequent fixation of the adjustment collar. A cooperating electrical connector can be detachably engaged with the electrical connector. A coupling member can be used to secure the cooperating electrical connector. | 03-24-2011 |
