The supporting portion 12 surrounds the ventilation path 10. The gas-permeable membrane 11 is bonded to the supporting portion 12 and closes the ventilation path 10 in a ventilatable manner. The protruding portion 13 is a part having a tubular shape, the part being arranged to protrude from the supporting portion 12 and surround one end of the ventilation path 10, the part being configured to be in contact with the edge 2f when the ventilation component 1 is attached to the edge 2f. The ventilation component 1 satisfies requirements 2.5≤Gs/Gt≤5.0 and 1.0≤{(Gs−Gt)/2}/Lt≤3.0.

An adsorbent system including an enclosure having a cavity defining a humidity-controlled environment and a body having or defining a channel therein. The body is coupled to the enclosure such that a first end of the channel is in selective fluid communication with an ambient environment and a second end of the channel is in fluid communication with the humidity-controlled environment. The system further includes an adsorbent material in the channel, wherein the channel and adsorbent material are configured such that inlet fluid flowing from the first end to the second end through the channel is flowable over at least a portion of the adsorbent material, and such that outlet fluid flowing from the second end to the first end is directly flowable over a majority of the portion of the adsorbent material that is flowable over by the inlet fluid, The system further includes a valve system positioned at or adjacent to or in fluid communication with the first end of the channel. The valve system includes an inlet valve portion that is biased to a closed position to generally block a flow of inlet fluid therethrough and that is movable to an open position when a pressure in the channel is sufficiently low relative to a pressure in the ambient environment. The valve system further includes an outlet valve portion that is biased to a closed position to generally block a flow of outlet fluid therethrough and that is movable to an open position when the pressure in the channel is sufficiently high relative to the pressure in the ambient environment.

A lighting and/or signaling device, in particular for the automotive industry, comprising a container body which delimits a containment housing closed by a lenticular body, which accommodates at least one light source adapted to emit a light beam which at least partially crosses the lenticular body, at least one decorative element, applied on an external wall of the lenticular body, opposite to the containment housing. An internal wall of the decorative element, directly facing the external wall of the lenticular body, comprises at least one welding pin, which creates a welding point with the lenticular body. At least one spacer element defines a minimum clearance and a volume or gap between the external wall of the lenticular body and the internal wall of the element decorative element. At least one conveyor element favors the outflow of liquids which have penetrated through the clearance into the volume.

An automotive lighting device including a light source, a driver arranged to control the operation of the light source, a housing, a desiccant salt and a separating element. The driver includes a driver cover arranged to dissipate the heat generated by the driver. The housing includes a housing wall and a ventilation element located in the housing wall, the ventilation element being configured to allow water vapour to exit the housing. The desiccant salt is arranged in thermal contact with the driver cover. The separating element is provided between the desiccant salt and the light source. A method for controlling the operation of the separating element is also provided.

A cover lens for a vehicle lighting device is provided, and includes a visual section which is transparent and designated to form the light exit aperture of the lighting device. The cover lens also includes a blank section which is opaque and/or which is designated to be invisible from the exterior of the lighting device. The blank section includes at least one condensation area. The wall thickness of the condensation area is lower than the wall thickness of the visual section.

A vehicle lamp 1 is provided with: a ventilating unit 10 that is provided with a first opening 2a of a closed case 2, prevents entry of liquids and solids to an inside space S within the case 2, and allows circulation of air between the inside space S and an outside space of the vehicle lamp 1; and a dehumidifying unit 20 that is provided in a second opening 2b of the case 2 different in position from the first opening 2a and has an electrolysis dehumidifying element for discharging water vapor in the inside space S to the outside of the vehicle lamp 1 by electrolysis. Thus, a dehumidifying device and a lamp that can rapidly discharge water vapor that has entered the inside of a housing to the outside of the housing can be provided.

An aircraft exterior light unit may comprise a magnetically controlled fluid drain valve configured to expel liquid water from the light unit. The valve may include a permanent magnet configured to induce a magnetic flux circuit that generates a magnetic force configured to close the valve. The valve may be configured to open when the pressure inside the light unit exceeds the magnetic force. As the valve opens and expels the water, the pressure within the light unit may decrease, equalizing with that of the external environment. As the magnetic force generated by the magnet increases as the valve is open and the water expelled, the magnet may be configured to close the valve once more. As such, the magnet may be configured to control a self-acting fluid drain valve in an aircraft exterior light.

Proposed is a moisture control module for an automobile lamp, the moisture control module includes a moisture absorption composition in the accommodating part and seals the moisture absorption composition with a breathable film and a cover, thereby reducing mounting time, space, and cost as compared with a pouch type absorbent. In addition, the moisture absorption performance continues for a long time, and when used in a closed device, which is prone to dew condensation inside according to temperature changes, especially when used in automobile lamps, the internal humidity is kept low, so that dew condensation does not occur inside, and at the same time, has the effect of preventing damage to the packaging material, etc.
