Abstract

A head lamp assembly including a housing; a plurality of head lamp cases installed in the housing, wherein each head lamp case comprises a light emitting diode (LED) light source, and a heat sink for dissipating heat generated from the LED light source; and a plurality of ventilating fans for circulating air in the plurality of head lamp cases and installed in the plurality of head lamp cases, respectively. Accordingly, the ventilating fans installed in the head lamp cases have opposite ventilating directions, and thus air is circulated in the head lamp cases by the ventilating fans to thus improve heat dissipation effects.

Claims

1. A head lamp assembly, comprising:

a housing; and

a plurality of head lamp cases disposed in the housing including a first head lamp case and a second head lamp case, wherein each of the first and second head lamp cases includes;

a light emitting diode (LED) light source,

a heat sink for dissipating heat generated from the LED light source, and

a ventilating fan configured to circulate air into and out of each of the first and second head lamp cases, wherein;

the ventilating fans of the first and second lamp cases are disposed in respective rear portions of the first and second lamp cases and are parallel with each other,

the ventilating fan of the first head lamp case is configured to cause the air to flow in from a front portion of the first head lamp case and flow out to the rear portion of the second head lamp case, and

the ventilating fan of the second head lamp case is configured to cause the air to flow in from the rear portion of the second lamp case and flow out to the front portion of the first head lamp case.

16. A vehicle comprising the head lamp assembly of any one of claims 1 through 15.

2. The head lamp assembly 1, wherein the ventilating fans of the plurality of head lamp cases have opposite ventilating directions.

3. The head lamp assembly 1, wherein the ventilating fan of each of the first and second head lamp cases is connected to an air inlet defined in one side of the head lamp case.

4. The head lamp assembly 1, wherein an air outlet is defined in one side of each of the first and second head lamp cases such that air is emitted out of each of the first and second head lamp cases by the ventilating fan of each of the first and second head lamp cases.

5. The head lamp assembly 1, further comprising a guide portion for guiding air towards the heat sink of each of the first and second head lamp cases.

6. The head lamp assembly 1, further comprising a transparent window for transmitting light and disposed in one side of the housing.

7. The head lamp assembly 6, wherein the head lamp assembly is sealed by the housing and the transparent window.

8. A head lamp assembly, comprising:

a housing; and

a transparent window for transmitting light and disposed in one side of the housing;

a plurality of head lamp cases disposed in the housing, wherein each of the plurality of head lamp cases includes;

a light emitting diode (LED) light source,

a heat sink for dissipating heat generated from the LED light source, and

a ventilating fan configured to circulate air in each of the plurality of head lamp cases and connected to an air inlet defined in a side surface of each of the plurality of head lamp cases, such that the ventilating fan emits air out of each of the plurality of head lamp cases to an air outlet defined in a lower surface of each of the plurality of head lamp cases.

9. The head lamp assembly of claim 8, wherein the ventilating fans of the plurality of head lamp case have opposite ventilating directions.

10. The head lamp assembly of claim 8, further comprising a guide portion for guiding air towards the heat sink of each of the plurality of head lamp cases.

11. The head lamp assembly of claim 8, wherein the head lamp assembly is sealed by the housing and the transparent window.

12. A head lamp assembly, comprising:

a housing;

a transparent window for transmitting light and disposed in one side of the housing; and

a plurality of head lamp cases disposed in the housing, wherein each of the plurality of head lamp cases includes;

a light emitting diode (LED) light source,

a heat sink for dissipating heat generated from the LED light source disposed on a top surface of the heat sink,

a ventilating fan configured to circulate air in each of the plurality of head lamp cases and connected to an air inlet defined in one side of each of the plurality of head lamp cases; and

to an air outlet defined in another side of each of the plurality of head lamp cases, and

a guide portion for guiding air towards the heat sink, the guide portion extending parallel with a bottom surface of the heat sink and being bent down toward the air outlet.

13. The head lamp assembly of claim 12, wherein the plurality of ventilating fans of the plurality of head lamp cases have opposite ventilating directions.

14. The head lamp assembly of claim 12, wherein an air outlet is defined in one side of each of the plurality of head lamp cases such that air is emitted out of each of the plurality of head lamp cases by the ventilating fan of each of the plurality of head lamp cases.

15. The head lamp assembly of claim 12, wherein the head lamp assembly is sealed by the housing and the transparent window.

17. A head lamp assembly, comprising:

a housing; and

a plurality of head lamp cases disposed in the housing, wherein each of the plurality of head lamp cases comprises;

a case;

a light emitting diode (LED) light source disposed within the case;

a heat sink disposed within the case for dissipating heat generated from the LED light source;

an air inlet defined in one side of the case;

a ventilating fan disposed in the case and connected to the air inlet;

an air outlet defined in one side of the case; and

a guide portion configured to guide air introduced through the air inlet by the ventilating fan towards the heat sink and allow the air to pass through the heat sink towards the air outlet to emit the air out of the case.

18. The head lamp assembly of claim 17, further comprising a transparent window for transmitting light and disposed in one side of the housing.

19. The head lamp assembly of claim 18, wherein the head lamp assembly is sealed by the housing and the transparent window.

20. The head lamp assembly of claim 17, wherein the ventilating fans of the plurality of head lamp cases have opposite ventilating directions.
