Abstract
A dehumidifier, and a lamp for a vehicle including the same, can include a dust cover including a first communicate hole therein, a moisture absorption cover disposed in the dust cover, in which a desiccant that absorbs a moisture included in the air can be accommodated, and in which a second communicate hole corresponding to the first communicate hole is formed, and a valve including a shape memory allow such that the valve is configured to selectively open the first communicate hole and the second communicate hole by the shape memory alloy being deformed by a temperature change.
Claims17
A dehumidifier for a lamp of a vehicle, comprising:
- a dust cover configured to be coupled to a vehicle lamp housing of the lamp of the vehicle, the dust cover including a first communicate hole therein;
- a desiccant;
- a moisture absorption cover disposed in the dust cover, wherein the moisture absorption cover accommodates the desiccant, wherein the moisture absorption cover includes a second communicate hole therein, and wherein the second communicate hole corresponds to the first communicate hole;
- a valve including a shape memory alloy such that the valve is configured to selectively open the first communicate hole and the second communicate hole by the shape memory alloy being deformed by a temperature change,
- wherein the valve comprises an opening/closing plate that includes the shape memory alloy and is configured to selectively open the first communicate hole and the second communicate hole according to the temperature change, and
- wherein the valve further comprises:
- a magnetic plate including a magnetic material and disposed at one of the first communicate hole and the second communicate hole;
- and
- a supporting plate coupled to the opening/closing plate and configured to be deformed depending on to a deformation of the opening/closing plate such that the supporting plate is selectively attached to the magnetic plate.

A dehumidifier of a lamp for a vehicle comprising:
- a dust cover configured to be coupled to a vehicle lamp housing of the lamp of the vehicle, the dust cover comprising a dust supporting bracket having a first cross-section in a first arc shape, and having a first communicate hole through the dust supporting bracket;
- a moisture absorption cover comprising a moisture absorption supporting bracket having a second cross-section in a second arc shape, and having a second communicate hole through the moisture absorption supporting bracket, wherein the second communicate hole at least partially aligns with the first communicate hole;
- and
- a valve disposed between the dust supporting bracket and the moisture absorption supporting bracket, wherein the valve includes a shape memory alloy, and wherein the valve is configured to selectively open the first communicate hole and the second communicate hole by the shape memory alloy being deformed by a temperature change,
- wherein the valve comprises:
- an opening/closing plate including the shape memory alloy and configured to selectively open the first communicate hole and the second communicate hole according to the temperature change;
- a magnetic plate including a magnetic material and disposed at one of the first communicate hole and the second communicate hole;
- a supporting plate coupled to the opening/closing plate and configured to be deformed according to a deformation of the opening/closing plate such that the supporting plate is selectively attached to the magnetic plate;
- and
- a sealing pad disposed on an outside of the supporting plate.
7 more elements
A lamp for a vehicle comprising:
- a lamp housing;
- a light source module within the lamp housing;
- and
- a dehumidifier attached to the lamp housing, wherein the dehumidifier comprises:
- a dust cover including a first communicate hole therein;
- a desiccant;
- a moisture absorption cover disposed in the dust cover, wherein the moisture absorption cover accommodates the desiccant, wherein the moisture absorption cover includes a second communicate hole therein, and wherein the second communicate hole corresponds to the first communicate hole;
- and a valve including a shape memory alloy such that the valve is configured to selectively open the first communicate hole and the second communicate hole by the shape memory alloy being deformed by a temperature change,
- wherein the valve comprises an opening/closing plate that includes the shape memory alloy and is configured to selectively open the first communicate hole and the second communicate hole according to the temperature change, and
- wherein the valve further comprises:
- a magnetic plate including a magnetic material and disposed at one of the first communicate hole and the second communicate hole;
- and
- a supporting plate coupled to the opening/closing plate and configured to be deformed depending on to a deformation of the opening/closing plate such that the supporting plate is selectively attached to the magnetic plate.
