  • Patent number: 11506364
    Abstract: A connection system for a linear lighting system has channels of adjacent luminaires coupled together by a coupling arrangement having a first plate, a second plate and fixings for clamping the first and second plates around wall portions of the two channels. The fixings are slidable along slots so that the coupling arrangement can be slid into an operable position or to an out-of-the way position for disassembly. One of the first and second plates comprises a spring member having sprung projections for projecting into the apertures, to provide an automatic clamping function when the coupling arrangement is tightened. For example, there may be an outer coupling plate and an inner spring plate which forms the spring member.

  • Patent number: 11486552
    Abstract: A method is described for deploying one or more illumination devices. The or each illumination device is self-contained and has a first state in which it is inoperative and a second state in which it is operative to provide illumination at at least one frequency within the range from and including infrared to and including ultraviolet. The method comprises the steps, optionally repeated at intervals, of: actuating a mechanism to move a said illumination device from a housing storing one or more illumination devices to an exposed position outside the housing; and automatically changing the state of the illumination device from its first state to its second state as a direct result of movement of the illumination device from within the housing to the exposed position.
