An apparatus and method for installing film into a detachable film cassette assembly including a film clip adapted to receive a film cartridge, a winding housing attached to the film clip, and first and second film covers. The structure includes a substrate, which includes an anchoring device, and a centrifugal mass, which is connected to the anchoring device via a flexible spring device, so that the centrifugal mass is elastically deflectable from its rest position. The display panel includes a plurality of pixels including a pixel circuit connected to a gate line, a data line, and a high-level voltage line. The transformer and lamp holders are mounted to an object and the electrical wires are tailored to the necessary installation dimensions, thereby providing a luminaire assembly that is easily and neatly installable to any object in any desired configuration. The body has an opening in the side wall for inserting the check valve. A time-resolving detector receives the fluorescence and at least a portion of the white light pulse and separates the fluorescence from the portion of the white light pulse.
