    • The invention relates to a light diffuser (1) comprised of a holding device and of an at least partially transparent inflatable bag (3), which can be detachably connected to said holding device. The holding device is equipped with an adapter ring (4) provided for attachment to a projector (2) and for holding the bag. In addition, the adapter ring is closed such that it is transparent and pressure sealed with regard to the attachment side, and means for supplying a gaseous filling medium are provided on the holding device. According to the invention, a compressed gas connection and an electronically actuatable valve for supplying gas are provided on the adapter ring. A first pressure sensor (7) determines the increasing inner pressure when the sack is fixed to the ring and sends a switch-off signal to the valve once an adjustable maximum pressure value is reached in order to automatically stop the filling. A second sensor (11) is also provided for detecting the ambient pressure so that a switch-off signal can be derived based on a predeterminable differential pressure value.
    • 本发明涉及一种光扩散器(1)由一个保持装置的,以及一与所述保持装置可释放地连接,至少部分地透光的充气袋(3),其中,所述保持装置包括在一侧上用于紧固到聚光灯的适配器环(4)(2)和,另一方面 还包括用于接收所述包,用于紧固侧透光性的适配环和经加压密封并设置在保持装置上的装置包括用于供应气态填充介质。 根据本发明,用于气体供给压缩气体连接和电致动阀被布置在适配器环,其中的第一压力传感器(7)确定的建筑物建立内部压力在固定在环状袋和在达到设定的最大压力值到阀一个关断信号上导致自动终止填充 , 此外,第二传感器(11)被设置用于检测环境压力使得预定压差值的基础上,一个关断信号可以导出。
