The preset invention provides a light unit attached to a vehicle, the unit including a ventilation mechanism configured to ventilate a space between an outer lens and a housing, wherein the ventilation mechanism includes a first passage including, at one end, a first opening connected to a communicating hole and communicating with the space, a second passage including, at one end, a second opening that opens to a front side of the vehicle, a third passage including, at one end, a third opening that opens to a rear side of the vehicle, and a connecting passage to which the other end of the first passage, the other end of the second passage, and the other end of the third passage are connected.

A holding member mounted to the case including the internal space, a holding member including the ventilation hole that provides ventilation between the internal space and the external space; a humidity-conditioning member provided midway in the ventilation hole of the holding member and absorbing water vapor; and a ventilation filter provided to the holding member, a ventilation filter being closer to the external space than the humidity-conditioning member is, a ventilation filter being permeable to a gas and preventing a liquid and a sold from entering the internal space.

A vehicle light assembly is provided that includes a light source, a lens in front of the light source, conductive circuitry provided on the lens and forming a capacitive sensor for sensing moisture on the lens and a heater for removing the moisture, and switching circuitry for selectively energizing one of the capacitive sensor and the heater.

A vehicle light assembly including a housing, a light source, a lens disposed in front of the light source, a light sensor disposed in the housing outside of light output from the light source directed at the lens for sensing light reflected off the lens caused by moisture, and a heater disposed on the lens for reducing the moisture when moisture is sensed.

A headlamp assembly including a light source element, an outer lens, a fan, and a bezel structure, wherein the bezel structure is disposed forward of the fan in a vehicle-longitudinal direction and includes an air flow directing feature directing air flow from the fan toward the inner surface of the lens. Embodiments of the headlamp assembly generate light using low-temperate light emitting diodes (LEDs) and direct air flow over components thermodynamically coupled to the LEDs such that the air absorbs heat from the components and distributes the heat throughout the headlamp assembly, especially on the inner surface of the outer lens to reduce the condensation thereon. Further, embodiments may include a bezel structure having a pair of vehicle-forward concave sections disposed at the forward end of the bezel structure that disperse air through the headlamp assembly in a wide aperture to distribute thermal energy more equally throughout the headlamp assembly.

An embodiment of the present invention relates to a vehicle lamp structure for removing condensation on a lens part. In particular, provided is a vehicle lamp comprising: a lens part; a light source part separated from the lens part; a bezel part which is adjacent to the light source part and provides a separation space between the lens part and the light source part; and a thermoelectric circulation part which is disposed outside the bezel part and includes a thermoelectric module which comprises a plurality of thermoelectric semiconductor devices and is disposed between a first substrate and a second substrate which face each other, wherein the thermoelectric circulation part enables air, which has passed through a first heat conversion member on the thermoelectric module, to flow into the separation space.

Fresnel lenses are arranged between a board and an outer lens in such a manner as to face at least one of LED chips. The Fresnel lenses are arranged close to a center of the outer lens in front view. Convex and dome-shaped lenses are arranged between the board and the outer lens in such a manner as to face other light sources of the LED chips. The dome-shaped lenses are arranged more radially outward than the Fresnel lenses in front view. Rear surface 89a of the dome-shaped lenses are arranged to be offset toward the LED chips relative to rear surfaces of the Fresnel lenses.

A headlamp reflector 12, which accepts a conventional lamp capsule 10 having a sealing gasket 64, has a neck 2 defining a bore 40 and socket 50 to receive and retain lamp capsule 10 with capsule latching structure 52. Reflector neck 2 has a gasket seating surface 47 adjacent to which one or more recessed channels 43 are formed which define air passageways 70 that communicate between inner reflector cavity 19 and neck entrance region 46, allowing air passage past gasket 64 with capsule 10 retained in socket 50, while still allowing gasket 64 to position capsule 10 in reflector bore 40. Gasket seating surface 47 may be located displaced axially from capsule latching structure 52. Embodiments of reflector 12 accommodate a variety of popular, commercially available replaceable lamp capsules 10.
