Vehicle lamp and vehicle including the same
According to an embodiment of the present invention, provided is a vehicle lamp including a housing, a lens unit that is provided on a front surface of the housing, a light source unit that is arranged to be spaced apart from the lens unit by a predetermined distance and thereby forms a separation space, a thermoelectric module that is provided inside the housing, an air flow passage unit that provides an air movement passage between the thermoelectric module and the separation space, and a thermoelectric circulating unit that provides power so that air passing through the thermoelectric module is discharged to the separation space along the air movement passage.
1. A vehicle lamp comprising:
a housing;
a lens unit that is provided on a front surface of the housing;
a light source unit that is arranged to be spaced apart from the lens unit by a predetermined distance and thereby forms a separation space;
a thermoelectric module that is provided inside the housing;
an air flow passage unit that provides an air movement passage between the thermoelectric module and the separation space; and
a thermoelectric circulating unit that provides power so that air passing through the thermoelectric module is discharged to the separation space along the air movement passage,
wherein the thermoelectric module includes a plurality of thermoelectric semiconductor devices between a first substrate and a second substrate which face each other and is arranged in such a manner that a heat generating area is implemented in the first substrate,
wherein a first thermal conversion member arranged on the first substrate and a first end of the air flow passage unit communicate with each other, and
wherein a second thermal conversion member arranged on the second substrate is exposed to the outside of the air flow passage unit.
2. The vehicle lamp of claim 1 , wherein a second end of the air flow passage unit communicates with the separation space.
3. The vehicle lamp of claim 2 , further comprising:
a bezel unit that is provided in the separation space.
4. The vehicle lamp of claim 3 , wherein the air flow passage unit is provided inside the bezel unit.
5. The vehicle lamp of claim 3 , wherein the air flow passage unit is provided on an outer surface of the bezel unit.
6. The vehicle lamp of claim 1 , wherein a vertical cross-sectional area of the first thermal conversion member and a vertical cross-sectional area of the first end of the air flow passage are the same with a predetermined tolerance.
7. The vehicle lamp of claim 6 , wherein the thermoelectric circulating unit communicates with the first end of the air flow passage unit through the first thermal conversion member and includes one or more first air-blowing modules.
8. The vehicle lamp of claim 1 ,
wherein the second thermal conversion member is arranged on the second substrate in which a heat absorbing area is implemented.
9. The vehicle lamp of claim 7 , wherein the second thermal conversion member is provided to be spaced apart from the first thermal conversion member by a predetermined distance.
10. The vehicle lamp of claim 7 , further comprising:
one or more second air blowing modules that is arranged inside the air flow passage unit.
11. The vehicle lamp of claim 3 , wherein the second end of the air flow passage unit is connected to an air discharge portion exposed to surface areas of the bezel unit.
12. The vehicle lamp of claim 11 , wherein the air discharge portion is provided in at least two areas of the surface areas of the bezel unit.
13. The vehicle lamp of claim 12 , wherein the air discharge portion is provided to discharge air in a downward direction of the lens unit.
14. The vehicle lamp of claim 12 , wherein the air discharge portion is provided to discharge air in an edge direction of the lens unit.
15. The vehicle lamp of claim 13 , wherein the air discharge portion is provided in at least one structure of a wedge-shaped hole structure and a slit structure.
16. The vehicle lamp of claim 1 , further comprising:
a temperature sensor unit that detects a temperature difference between the separation space inside the housing and the outside of the housing.
17. The vehicle lamp of claim 16 , further comprising:
a control unit that controls an operation of the thermoelectric circulating unit according to the temperature difference.
18. A vehicle that includes the vehicle lamp according to claim 1 .
