Abstract: A vehicle includes a disinfection system for combating biological, viral, fungal and parasitic agents. The vehicle includes a power source and is configured to generate at least one signal indicative the vehicle operation status. The disinfection system includes at least one electromagnetic emission device arranged to emit electromagnetic radiation; a controller having a plurality of stored scenarios. The controller is configured to receive the signal and to use the signal to select a scenario from the plurality of stored scenarios. The controller has output means to output control signals to the at least one electromagnetic emission device to control at least one of the intensity, wavelength, and duration of the emitted electromagnetic radiation in response to the selected scenario.

Abstract: An LED lighting assembly (1) comprising a cassette (2), a lens, a printed circuit board, PCB, (6) having at least one LED light source mounted thereon, the lighting assembly comprising an LED driver circuit arranged to maintain conduction in the circuit, the PCB using a first amount of power and wherein the LED driver circuit is arranged to simulate use of a second amount of power, the second amount being lower than the first amount. The LED lighting assembly comprises a capacitor arranged to be activated when a voltage across the LED driver circuit is below a first predetermined level. A resistor or resistor/capacitor combination is connectable to a trickle sensor in a passenger service unit (PSU).

Abstract: An LED lighting assembly (1) is provided comprising a cassette (2), a lens, a printed circuit board (6) having at least one light source mounted thereon wherein the lighting assembly comprises a collimator (12) provided between the LED light source and the lens, the collimator (12) comprising an optical cavity in the form of a linear mixing chamber and wherein the or each wall (14) of the mixing chamber comprises a reflective surface. A diffuse reflector film may be provided. The lens may comprise a lens assembly (40) which may be a focusing lens assembly. In some embodiments an LED lighting assembly is provided comprising a cassette (2), a lens, a printed circuit board (6) having at least one LED light source mounted thereon wherein the lighting assembly comprises a light output from the or each LED light source and wherein the light output is arranged to pass through a bevelled aperture (32).
