    摘要: The present invention relates to a control system (10; 30; 50) for a LED luminary (12) including a plurality of LED light sources of multiple colors for producing a mixed color light. The control system comprises means (22) for controlling the LED light sources in accordance with a difference between set point values representing a desired light output and first control data provided by at least one optical sensor (14; 32) responsive to a property of the light produced by the LED light sources. The control system is characterized by means (26; 38) for compensating said set point values in accordance with second control data provided by a temperature sensor (24) responsive to the temperature of the optical sensor(s) (14; 32). The additional temperature sensor makes it possible to compensate for changes in the spectral sensitivity of the optical sensor(s), whereby the color stability of the LED luminary with integrated optical sensors can be increased. The invention also relates to a corresponding control method.

    摘要: Low-pressure mercury vapor discharge lamp comprises a light-transmitting discharge vessel (10) enclosing, in a gastight manner, a discharge space (13) provided with a filling of mercury and a rare gas. The discharge vessel comprises discharge means (20a; 20b) for maintaining a discharge in the discharge space. The discharge vessel is provided with a container comprising an amalgam (2). The container is provided with releasing means (4) for the controlled release of mercury vapor from the amalgam. The releasing means is open during lamp operation and is substantially closed when, during lamp operation, the temperature of the amalgam becomes higher than a pre-determined temperature. Preferably, the pre-determined temperature corresponds to a temperature of a range of temperatures at which the mercury-vapor pressure above the amalgam is relatively stable.
