A method for feedback of a temperature setting of an air-conditioning device involves adjusting a light color of at least one lighting element for the display of a set temperature. The adjusted light color corresponds to a temperature setting of an airflow zone in a motor vehicle.

An interior trim of a vehicle includes a trim panel disposed in an interior space of the vehicle and including a plurality of cells configured to be respectively opened or closed. The plurality of cells define openings facing towards the interior space of the vehicle during an opening operation of the plurality of cells. The openings are arranged so that sound, light or air is discharged through the openings to the interior space of the vehicle.

An illuminated aircraft passenger cabin gasper comprises an air outlet for outputting a flow of air into an aircraft passenger cabin and an air guide, movably arranged within the air outlet for adjusting the flow of air that includes a light guide. The gasper also includes at least one light source, arranged adjacent to the light guide for coupling light into the light guide. The light guide has a light output surface for coupling light out of the light guide into the aircraft passenger cabin.

Provided is a lighting device for an automobile air vent. The lighting device for an automobile air vent has a variable resistor, a light emitter, a light guide, and a diffusion plate. The variable resistor is connected to a knob of an air vent and is configured to vary resistance according to a manipulation amount of the knob. The light emitter is connected to the variable resistor and is configured to emit light such that brightness or color of the light is varied according to the variable resistance varied by the variable resistor. The light guide is configured to guide the light emitted by the light emitter. The diffusion plate is installed in an air vent housing of the air vent and is configured to diffuse the light guided through the light guide.

A sterilizable lamp assembly of a vehicle may include at least one sterilizing lamp mounted in an indoor of a vehicle and for irradiating sterilizable light of wavelength to the interior of the vehicle, wherein the sterilizing lamp is configured to emit light when a passenger does not get on the interior of the vehicle.

An air-guiding arrangement for an air vent, includes an air-guiding element and an operating element which is movable relative to the air-guiding element and has a manually actuatable operating portion arranged on a front side of the air-guiding element, a light source being arranged in the operating portion of the operating element, at least one electrical conductor being provided which is connected, on the one hand, to the light source and can be connected, on the other hand, to an electrical supply source, and, for electrical connection between the light source and the at least one electrical conductor, at least one elastic electrical connecting element being provided which, on the one hand, is held fixedly on the air-guiding element and, on the other hand, is held fixedly on the operating element, and which deforms elastically during a relative movement between the air-guiding element and operating element.

An apparatus is provided for distributing indirect lighting and airflow to an individual passenger in a motor vehicle. That apparatus includes a vent body having an air inlet and an air outlet. An air valve is carried on the vent body. The air valve is displaceable between an open position and a closed position. A flexible air guide carried on the vent body is adapted to direct air from the air outlet toward the individual passenger.

A combined luminaire and air conditioning nozzle includes a front panel (101) with an opening. A nozzle frame (103) is pivotably connected to the opening of the front panel (101) so as to separate an air cavity (105) located behind the front panel (101) from a front side of the front panel (101). The structure includes a controller element (106) with a closing mechanism mechanically coupled thereto and arranged to adjustably limit an air passage (107) from the air cavity (105) to the front side of the front panel (101) in response to a movement of the controller element (106). A luminaire element (108) forms part of the closing mechanism and is provided with a light source arranged to output light to the front side of the front panel (101). The closing mechanism is arranged to convert a movement of the controller element (106) into a movement of the luminaire element (108), so that said adjustable limiting of the air passage (107) occurs as a result of said movement of the luminaire element (108).

A vehicle interior panel includes a diffuser spanning an air discharge opening. The diffuser has a spiral slot formed therethrough such that changing an axial distance between opposite ends of the slot changes an air flow capacity of the diffuser. The diffuser has an elegant and simplified design and can be made as one piece from a sheet material. Air is discharged from the diffuser radially and substantially equally in all radial directions. The diffuser can also function to provide ambient light from a light source and/or to deliver an air freshening agent to the passenger cabin.
