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.

Disclosed is an air vent device for a vehicle lamp, including: an inner housing which is installed on a lamp housing, has an opening portion formed at one side thereof, and has a moisture generation inducing zone that is formed in the inner housing and generates moisture; and an outer housing which has a low pressure inducing unit that is formed between the inner housing and the outer housing and allows the outside air to pass therethrough, and discharges the moisture generated in the moisture generation inducing zone to the outside through the opening portion and the low pressure inducing unit.

A high beam and low beam switching device, a vehicle lamp comprising the high beam and low beam switching device, and a vehicle, the device comprising a light shielding plate, an impeller, and a driving device that is used for driving the light shielding plate and the impeller to rotate forwards and backwards; and a limiting mechanism used for limiting the rotation angle of the light shielding plate is provided between the light shielding plate and the driving device. The high-beam and low-beam switching device can achieve the successful switching of a high beam and a low beam, and the use of a vehicle lamp will not be affected; mist or moisture in the interior of the vehicle lamp can be removed, and meanwhile, the heat dissipation effect of the vehicle lamp can be improved, and the space that is occupied by the vehicle lamp will not be increased.

A ventilation housing includes a housing and ventilation component. A housing tubular projecting part has a communicating hole between housing inner and outer spaces. The ventilation component has: an attachment member over the projecting part with a contacting inner surface; an attachment member supported ventilation body covering a hole end portion between the inner and outer spaces; and a covering member including peripheral and top parts over the attachment member. At least one ventilation path connects the ventilation body and the outer space. A first contact part between an attachment member outer surface outermost protruding portion and covering member peripheral part inner surface is closer to the inner space than an end portion on the outer space side in a second contact part being a contact portion between the housing projecting part outer surface and the attachment member inner surface.

A moisture absorbent for a vehicle lamp includes a first inorganic material, a second inorganic material, alkali metal phosphate, and a polymer wax are included. A composite moisture absorbent structure includes a first moisture absorbent pack including a powder type moisture absorbent and a second moisture absorbent pack including a capsule type moisture absorbent are embedded.

A vehicle lamp including a light source, a glass disposed in front of the light source, a housing supporting the light source and the glass, and a thermoelectric element unit generating cold wind and hot wind. The thermoelectric element unit includes a first part connected to the first flow path and generating one of cold air and hot air, a second part connected to the second flow path and generating the other one of the cold air and the hot air, a body accommodating the first part and the second part and having an opening formed on an upper surface, and a fan configured to be disposed on the opening of the body and introduce the air in a direction from the upper surface to a lower surface of the body. The thermoelectric element unit is positioned on an upper end of an external rear surface of the housing.

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.

A ventilation housing includes a housing and ventilation component. A housing tubular projecting part has a communicating hole between housing inner and outer spaces. The ventilation component has: an attachment member over the projecting part with a contacting inner surface; an attachment member supported ventilation body covering a hole end portion between the inner and outer spaces; and a covering member including peripheral and top parts over the attachment member. At least one ventilation path connects the ventilation body and the outer space. A first contact part between an attachment member outer surface outermost protruding portion and covering member peripheral part inner surface is closer to the inner space than an end portion on the outer space side in a second contact part being a contact portion between the housing projecting part outer surface and the attachment member inner surface.

A ventilation housing of the present disclosure includes: a housing; and a ventilation assembly. The housing includes a tubular projection extending to project from an outer surface and internally having a first space communicating the inside and the outside of the housing. The ventilation assembly includes: an internal member being a tubular body having an opening at a first end portion and an opening at a second end portion; a gas-permeable membrane covering the opening at the first end portion of the internal member; and an external member being a tubular body having a bottom, the external member being joined to the internal member with the internal member inserted in the interior of the external member from the first end portion side. The ventilation assembly is fixed to the projection with the projection inserted in the opening at the second end portion of the internal member to make an inner peripheral surface of the internal member and an outer peripheral surface of the projection abut each other. The ventilation assembly has a second space serving as a ventilation path connecting the gas-permeable membrane and the outside of the ventilation assembly in the inside of the internal member, the inside of the external member, and/or an interspace between the internal member and the external member joined together.
