Patent number: 11405993Abstract: The invention relates to a lighting device which is operable in two modes. In a first operating mode the flux of a lighting effect having a specified chromaticity is rendered based on the maximum (luminous) flux at which the chromaticity can be rendered by the lighting device. This can cause the maximum (luminous) flux across a range of colors that the lighting device can render to vary greatly. For example, a white color may be rendered at a far greater intensity than a primary color. In a second operating mode the specified chromaticity is rendered based on a predetermined maximum (luminous) flux for that specified chromaticity, or a color range that it is comprised in, or a predetermined maximum (luminous) flux for one or more color channels that are used in combination to render the light effect. This reduces the differences in maximum (luminous) flux of lighting effects rendered across the range of colors that are rendered by the lighting device.Type: GrantFiled: October 22, 2019Date of Patent: August 2, 2022Assignee: SIGNIFY HOLDING B.V.Inventors: Dragan Sekulovski, Berend Jan Willem Ter Weeme, Antonie Leonardus Johannes Kamp, Dzmitry Viktorovich Aliakseyeu
