Patent number: 11067234Abstract: A lighting device comprises a carrier having a radially outwardly facing mounting surface and an inner cavity radially within the outer mounting surface. Solid state lighting devices are mounted on the outer mounting surface and a driver is housed in the inner cavity. A ring shaped optical unit defines a light output region of the lighting device and is mounted around the carrier. An outer housing reflects light from the arrangement of solid state lighting devices to the ring shaped optical unit. This provides a compact arrangement, in which the driver, the heat sink (implemented by the carrier), and the solid state lighting arrangement are essentially in a plane. This is possible by providing a ring of light sources facing radially outwardly, with the driver mounted radially inside the ring. The radial light output is converted to a light output with a desired direction and beam shape by the optical unit.Type: GrantFiled: January 13, 2017Date of Patent: July 20, 2021Assignee: Signify Holding B.V.Inventors: Julie Bonnetto, Thomas Deflandre, Joachim Paul Jusselme, Rémi Noirot, Nicolas Mignot, Theo Renaudin

Patent number: 11060693Abstract: An optical system has a set of inner portions, each for mounting over an LED or LED arrangement, and an outer portion, for mounting over the inner portion. The outer portion is adapted to be mountable over each one of the set of inner portions, thereby to form an output lens when the outer portion is mounted over a selected one of the set of inner portions. The output lens has an overall optical function which depends on the selected inner portion. In this way, an optical lens function may be selected simply by choosing an appropriate one from a set of inner portions (or by not using an inner portion at all). The inner portions are low cost components, and they avoid the need for any tooling changes to the larger outer portions.Type: GrantFiled: June 12, 2018Date of Patent: July 13, 2021Assignee: SIGNIFY HOLDING B.V.Inventor: Remi Noirot

Patent number: 7918082Abstract: A method is intended for desulfation of a nitric oxide trap (22) and regeneration of a particle filter (24) arranged in an exhaust line (20) for treating exhaust gas from an internal-combustion engine (10), notably a Diesel engine. The saturation rate of the trap and the clogging rate of the filter are evaluated and, as soon as one of the rates reaches a threshold value, the fuel/air ratio of the exhaust gas is increased without it reaching a fuel/air ratio of 1, then desulfation of trap (22) is performed in association with regeneration of particle filter (24).Type: GrantFiled: November 24, 2004Date of Patent: April 5, 2011Assignees: Institut Francais du Petrole, Peugeot Citroen Automobiles SA, PCA SAInventors: Rémi Noirot, Michel Castagne, Jean-Baptiste Dementhon

Patent number: 7694509Abstract: The invention relates to a method for regenerating a particle filter (10) integrated into an exhaust line (12) of an internal combustion engine (34), wherein the exhaust gas flows into the filter via an inflow surface (16) and exit the filter via an outflow surface (18). According to the invention, the internal temperature of at least two regions of the filter (10) is monitored during regeneration of the filter; the oxygen content of the exhaust gas is reduced if at least one of the monitored temperatures rises above a critical temperature; the oxygen content of the exhaust gas is increased in order to continue regeneration if all of the monitored temperatures are below said critical temperature.Type: GrantFiled: November 23, 2004Date of Patent: April 13, 2010Assignee: Institut Francais du PetroleInventors: Rémi Noirot, Michel Castagne, Jean-Baptiste Dementhon
