Systems including a moisture pump for removing moisture from an inside environment to an outside environment. The moisture pump includes a housing defining a chamber with a heater, a heat spreader, and a desiccant for selectively adsorbing water vapor in the heating chamber when the heater is off and desorbing water vapor into the heating chamber when the heater is on. A valve assembly is also maintained by the housing transitionable between an adsorption position and desorption position. The adsorption position allows water vapor to be selectively transmitted into the heating chamber from the inside environment. The desorption position allows water vapor to be transmitted from the heating chamber for transmission into the outside environment. The adsorption and desorption ports can have asymmetric adsorption and desorption areas.

The present disclosure generally relates to apparatus and methods for controlling ventilation and temperature around a light source. A ventilation and temperature control assembly configured to selectively facilitate air circulation in an enclosure around a light source is disclosed. In some embodiments, a temperature sensor may be disposed near the light source. The air circulation may be switched on and off according to temperature measurement of the temperature sensor. In some embodiments, the ventilation and temperature control assembly includes a valve to selectively open and close a flow path in the ventilation and temperature control assembly.

Disclosed is a vehicular lamp. This vehicular lamp comprises: a light source; glass disposed in front of the light source; a housing supporting the light source and the glass and forming the exterior; a thermoelectric element unit which generates cold wind and warm wind by introducing air outside the housing into the housing; a first flow path through which one of the cold wind or the warm wind generated in the thermoelectric element unit flows into the housing; and a second flow path through which the other one of the cold wind or the warm wind is discharged outside the housing. The thermoelectric element includes: a first part connected to the first flow path and generating one of cold air or warm air; a second part connected to the second flow path and generating the other one of the cold air or the warm air; a body part which partitions arrange spaces for the first part and the second part and has an opening formed in the bottom surface; a first fan which is disposed in the opening of the body part and generates an inflow of air from the lower side to the upper side; and a second fan which is disposed inside the housing and circulates the air that has flowed into the first flow path.
