Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a head lamp,

The present invention relates to a head lamp for a vehicle, which can prevent moisture from being generated inside a head lamp of a vehicle by liquefying and discharging air introduced from the atmosphere, And a device for removing water from the lamp.

Generally, the vehicle is provided with an equalizing device for the purpose of making it possible to view objects in the driving direction in a dark place such as night driving, and to inform other vehicles or road users of the running state of the vehicle. A head lamp, which is also referred to as a headlight of the above equalizing apparatus, plays an important role not only in terms of function but also in terms of design.

The headlamp serves as an illuminating lamp functionally functioning to illuminate the course ahead of the vehicle, but also serves as an important factor for determining the design of the vehicle which is disposed at the front portion of the vehicle and visually illuminated. Therefore, it is preferable that the headlamp is kept in a moisture-free state in the lens for securing a good watch and a clean design.

However, condensation water may be generated on the inner surface of the lens by the temperature difference generated in the inside and the outside of the headlamp. Alternatively, when the head lamp stops operating, the heat generated by the light source disappears, causing the temperature inside the head lamp to drop below the dew point, thereby generating dew on the head lamp. In the case where the head lamp is wet with moisture, the light distribution performance of the head lamp is not only deteriorated in appearance but also the durability of the head lamp is low.

It should be understood that the foregoing description of the background art is merely for the purpose of promoting an understanding of the background of the present invention and is not to be construed as an admission that the prior art is known to those skilled in the art.

FIG. 1 is a view showing a state in which a head lamp 100 according to an embodiment of the present invention is mounted with a water removal device for a vehicle headlight. FIG. 2 is a view showing part A of FIG. 1 in detail, 3 is a view showing a state in which the air inlet 500 of FIG. 2 is removed. FIG. 4 is a sectional view taken along line BB of FIG. 2, FIGS. 5 to 6 are views showing an embodiment of a water condensing portion 700, and FIGS. 7 to 8 are views showing an embodiment of the moisture suction portion 900 . 9 to 10 are views showing an apparatus for removing moisture of a headlamp for a vehicle according to a second embodiment and a third embodiment of the present invention.

The apparatus for removing moisture of a headlamp according to an embodiment of the present invention includes a housing 300 having an opening face formed on a front surface of a vehicle, a light source disposed inside the housing 300 to generate light, A headlamp water removing apparatus for a vehicle headlamp that removes moisture generated in a headlamp (100) including a lens unit to cover the headlamp (100), the apparatus comprising: A water flocculating portion 700 for allowing water to flocculate therein; And a water suction unit (900) for causing the coagulated water to move to the moisture condensing unit (700) and then discharging the moved moisture to the outside.

The apparatus for removing moisture of a vehicle head lamp according to the present invention is provided in a conventional head lamp 100, and a plurality of water removal apparatuses can be installed behind the housing 300, as shown in FIG.

A through hole 310 communicating with the outside is formed on the rear surface of the housing 300. One end of the air inlet 500 is connected to the through hole 310 and the other end is connected to the atmosphere so that atmospheric air is supplied to the head lamp 100 through the through hole 310. Particularly, the through hole 310 is formed with a rearwardly extending coupling part 330. The coupling part 330 is inserted into the air inlet part 500 and is supported by the housing 300, The coupling of the part 500 can be made more robust.

The air inflow part 500 is a vent pipe such as a pipe or a tube through which air can pass, and particularly extends from the housing 300 toward the rear of the vehicle as shown in FIG. 2, And is bent toward the front of the vehicle. That is, as shown in Fig. 4, the cross section is formed to have a "C" shape. Accordingly, since the length of the air flowing in the air after the inflow of air is increased, the electromagnetic force due to the static electricity generated by the introduced air can be increased. Of course, the cross section can be formed to have various types of paths such as "- "," a ", and "

Particularly, the air inflow part 500 is formed of a carbon-based material, thereby generating an electrostatic field by friction between the air to be sucked and carbon, thereby allowing moisture in the air to cohere to the water condensing part 700 . The principle of the water flocculation in the water flocculation unit 700 will be described later.

According to the first embodiment shown in FIGS. 1 to 8, the water condensing part 700 is located in the air inflow part 500, and when water is supplied from the air, Let it coalesce. The water agglomerating unit 700 may have a shape as shown in FIGS.

5, the moisture agglomerating unit 700 is a first embodiment of the water agglomerating unit 700. As shown in FIG. 5, the water agglomerating unit 700 is an electrically conductive conductor, and may be a thin line or a thin and long plate- , And is formed in a spiral shape in which the radius is gradually increased from the center, while the interval is minimized. An insulator 710 is provided to prevent fire due to moisture and electricity.

6 is a second embodiment of the water agglomerating unit 700. As shown in FIG. 6, the water agglomerating unit 700 is a conductor through which electricity flows, and is formed into a polygon having different sizes, . Particularly, it is more effective to use a polygon close to a circle for the polygon. The polygons are arranged concentrically, and an insulator 710 is provided to prevent fire due to moisture and electricity.

The moisture suction unit 900 moves moisture accumulated in the moisture condenser 700 to the inside of the moisture suction unit 900 and then discharges the moved moisture to the outside. The water suction unit 900 is formed by the porous tube 910 and the water suction unit 900 and the water flocculation unit 700 are closely contacted with each other. The water is moved to the moisture suction portion by the development, and the moved moisture is formed to be discharged to the outside.

The cross-section of the porous tube 910 may be formed by selecting any one of a circular shape and a polygonal shape having a triangular shape or more. The cross section of an embodiment of the porous tube 910 is shown in Figs.

The porous pipe 910 is formed of a metal such as SPC (Steel Plate Commerical) or stainless steel, which is electrically conductive but does not generate rust and ensures strength. In particular, the porous pipe 910 is made of a carbon- And may be formed of a material.

In addition, the water suction unit 900 may be formed of a porous material such as a sponge, a cloth, and a cotton pad. The water suction unit 900 and the water flocculation unit 700 are closely attached to each other so that water in the water flocculation unit 700 is moved to the water suction unit 900 by capillary phenomenon, As shown in FIG.

The water suction unit 900 is provided with a plurality of capillaries inside and the water suction unit 900 and the water flocculation unit 700 are closely attached to each other. To the moisture suction unit (900), and the moved moisture is formed to be discharged to the outside.

The structure of the air inlet part 500, the water condensation part 700 and the water suction part 900 may be used to connect the head lamp 100 to the housing 300 through the air inlet part 500. [ The moisture contained in the air flowing into the inside can be removed by van der Waals' force formed in the water condensing part 700. [ do. Here, the Van der Waals force is a weak attractive force generated between electrically neutral molecules, and the molecular structure of water is located at the center of the oxygen molecule and the hydrogen molecule is located at both sides of the oxygen molecule, It is used to adsorb moisture.

That is, when the power is applied to the water condensing unit 700, the air introduced into the air inlet 500 through the carbon inlet 500 flows through the air inlet 500, As a result, carbon and air are brought into contact with each other and electrostatic fields are generated by friction. Therefore, the static electricity is accumulated as positive electric charge in the carbon tube, and as a negative charge is discharged to the water suction unit 900, a high-voltage electrostatic field is formed in a direction perpendicular to the flow of the air in the air inlet unit 500. The moisture contained in the air passing through the electrostatic field thus formed is affected by the van der Waals force, so that a negative charge of hydrogen is formed toward the positively charged air inflow part 500, and the negatively charged A positive charge of oxygen in the water toward the water suction unit 900 forms an attractive force so that the water remains as a force inside the air passage when passing through the air suction unit. Therefore, by using the van der Waals force as described above, the dry air from which moisture has been removed can be introduced into the interior of the housing 300 of the headlamp 100.

The method of removing moisture from the head lamp 100 may be sequentially performed by connecting the head lamp 100 with a power line 600 through a circuit of the connector 800 of the head lamp 100 or through a connector 800 of a vehicle A power source is applied to the water flocculation unit 700 to form a magnetic field. When air in the air containing moisture is introduced through the air inflow part 500, an attractive force is generated by the force of the van der Waals force between the water cohesion part 700 and moisture, ). ≪ / RTI > Accordingly, water is condensed, and a tensile force is generated between the condensed water and the water suction unit 900 configured by selecting one of the hollow fiber membranes or the porous material or the capillary tube, and moisture is transferred to the water suction unit 900 . At this time, since the tensile force generated between the moisture suction unit 900 and the moisture is larger than the gravity acting on the moisture, moisture is moved from the moisture condensation unit 700 to the moisture suction unit 900. Thereafter, the moisture moved to the moisture suction unit 900 is moved to the outside through the capillary tube provided in the water suction unit 900, so that moisture is discharged to the outside of the head lamp 100, And flows into the inside of the head lamp 100.

9 to 10, a diagram showing a moisture removing device for a vehicle headlamp according to a second embodiment and a third embodiment of the present invention will be described. A water flocculation unit 700 installed in the air flow path in the housing 300 to cause water in the air to flocculate therein when power is applied; And a water suction unit 900 for allowing water to be agglomerated in the water agglomerating unit 700 to be discharged and then discharging the transferred moisture to the outside, thereby exhibiting a van der Waals force. The connector 800 and the moisture condensing unit 700 are connected to the power supply line 600 by the power supply 600. The power supply 600 supplies power to the connector 800 and the water condensing unit 700, Lt; / RTI > This configuration is the second embodiment shown in Fig.

Particularly, the through hole 310 communicating with the outside is formed on the rear surface of the housing 300, and the moisture condensing part 700 and the moisture suction part 900 are installed in the air flow path in the housing 300 The water condensing part 700 and the water suction part 900 are installed in the bracket 400 which can be inserted or drawn out through the through hole 310. [ This configuration is the third embodiment shown in Fig. Therefore, in the case of the third embodiment, it is easy to replace the water condensing part 700 or the water suction part 900 in case of failure, and the maintenance of parts is easy.

Therefore, according to the apparatus for removing moisture of a vehicle head lamp, it is possible to easily remove water, which is a root cause of the moisture problem of the head lamp 100, by removing moisture in the air flowing into the head lamp 100 through an electrical force By eliminating the antifogging coating, it is possible to obtain a cost saving effect and an effect of extending the life of electronic equipment.

In addition, there is an advantage of preventing the headlamp 100 from being wetted by moisture, thereby increasing the durability of the headlamp 100 and preventing deterioration of the light distribution performance of the headlamp 100. [
