Patent number: 11852321Abstract: Example embodiments relate to movable lens luminaires. One example luminaire head includes a first support that includes a plurality of light sources. The luminaire head also includes a second support that includes a plurality of lens elements associated with the plurality of light sources. A lens element of the plurality of lens elements has an internal surface facing a light source of the plurality of light sources and an external surface. Further, the luminaire head includes a moving means configured to move the second support with respect to the first support, such that a position of the plurality of lens elements geometrically projected on a surface of the first support is changed. The lens element has a varying profile seen in a movement direction of the moving means. The lens element includes a prismatic portion, a collimator portion, or a diffusor portion.Type: GrantFiled: May 18, 2022Date of Patent: December 26, 2023Assignee: Schreder S.A.Inventors: Vincent Lang, Michel Delvaux, Roxane Caprara

Publication number: 20230209692Abstract: Example embodiments relate to systems for checking a luminaire status and methods thereof. One embodiment includes a method for checking a status of a luminaire using a mobile terminal in a vicinity of the luminaire. The mobile terminal includes a sensing means, a memory, and a communication means. The method includes obtaining, by the mobile terminal, an identifier of the luminaire. The method also includes determining, based on the obtained identifier of the luminaire, a measure of the status of the luminaire to be acquired. Additionally, the method includes acquiring, by the sensing means of the mobile terminal, the measure of the luminaire status. Further, the method includes storing, in the memory of the mobile terminal, data about the acquired measure of the luminaire status. The data is associated to the identifier of the luminaire.Type: ApplicationFiled: March 26, 2021Publication date: June 29, 2023Inventors: Vincent Lang, Laurent Secretin
