Description
The present invention relates to an adaptive headlamp for a vehicle, and more particularly, to an adaptive headlamp for a vehicle, and more particularly, to an adaptive headlamp for a vehicle, in which, among light beams emitted from a plurality of light sources and irradiated to the outside, And more particularly, to an adaptive headlamp for a vehicle capable of forming a uniform and smooth beam pattern without the necessity of forming a uniform beam pattern.
2. Description of the Related Art Generally, a vehicle has various types of lamps having a lighting function for easily confirming an object located in the vicinity of the vehicle at nighttime, and a signal function for notifying other vehicles or road users of the running state of the vehicle.
For example, a head lamp and a fog lamp, which are mainly used for a lighting function function, a turn signal lamp, a tail lamp, a brake lamp, Lamps (Brake lamp), side markers (side markers), and the like. These lamps are regulated by the laws and regulations for their installation standards and specifications so that each function can be fully utilized.
Among the lamps for a vehicle, the headlamp forms a low beam pattern or a high beam pattern so as to ensure the driver's front view when the vehicle is traveling in a dark environment such as at night, and plays a very important role in safety operation .
Such a headlamp is required to maintain a low beam pattern in normal operation so as to prevent the driver of the opposed vehicle traveling in the opposite direction or the driver of the preceding vehicle from being glare-induced in normal operation, A high beam pattern is formed in accordance with the present invention to ensure safe operation.
However, there is a case where a high beam pattern is formed in a state in which the opposite vehicle or the preceding vehicle can not be recognized. In such a case, there is a problem in that safety accidents are caused by causing glare to the opposite vehicle driver or the lead vehicle driver.
Accordingly, in recent years, when a vehicle or a preceding vehicle is detected while driving in a state in which a high beam pattern is formed, the angle of light illumination, brightness, width, and length of the lamp are automatically adjusted so that the opponent vehicle or the lead- An adaptive driving beam (ADB) headlamp, that is, an adaptive headlamp is provided.
The adaptive headlamp is a dynamic type in which a dark zone is formed in a space where the opposing vehicle or the preceding vehicle is located by changing the angle of the ramp by the swivel actuator when the opposing vehicle or the preceding vehicle is sensed. And a matrix type in which a light block is formed in a space in which the opposing vehicle or the preceding vehicle is located by selectively turning on or off a plurality of light sources.
Here, in the case of the adaptive headlamp of the matrix type, a plurality of light sources are closely arranged so that the beam patterns formed by the lights emitted from the respective light sources are spaced apart from each other so as not to form a dark zone, It causes rise.
That is, as the plurality of light sources are densely arranged so that the beam patterns of the light beams emitted from the adjacent light sources are not spaced from each other, the number of light sources increases, thereby increasing the manufacturing cost, By selectively turning on or off the light sources, energy consumption is also great.
SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is an object of the present invention to provide a method and an apparatus for correcting beam patterns, which are emitted from a plurality of light sources, So as to prevent the occurrence of cancer stagnation.
In particular, the technical problem to be solved by the present invention is to provide an adaptive headlamp for a vehicle in which a beam pattern adjacent to each other is overlapped with a certain area so as to form a uniform and smooth beam pattern without generation of a dark zone between beam patterns .
The problems of the present invention are not limited to the above-mentioned problems, and other problems not mentioned can be clearly understood by those skilled in the art from the following description.
According to an aspect of the present invention, there is provided an adaptive headlamp for a vehicle, comprising: a plurality of light sources; A plurality of light guides arranged in a light emitting direction of the light source and irradiating the light forward while refracting the light emitted from the light source; And a light mixing part for mixing the light in a predetermined area; And a lens that transmits light that has passed through the light mixing portion of the collective lens and mixed with each other in a predetermined region to the outside.
In this case, in the above-mentioned aggregate lens, the light guide and the light mixing section may be integrated.
Here, the light guides are provided in a number corresponding to the number of the light sources, respectively, and an incident surface is formed on one side, and one outgoing surface may be formed in the light mixing portion.
It is preferable that the width of the light guide located on the outboard side is larger than the width of the light guide located on the inboard side of the vehicle.
On the other hand, the light guide may gradually increase in width from the light guide located on the inboard side of the vehicle to the outboard side light guide.
Further, the lens may be an aspherical lens.
On the other hand, the focus of the lens and the focus of the collective lens may be defocused.
Also, it is preferable that at least a part of the beam patterns adjacent to each other among the beam patterns formed by the light emitted from the light source are overlapped.
In this case, among the beam patterns formed by the light emitted from the light source, adjacent beam patterns may be overlapped by at least 50% or more.
Other specific details of the invention are included in the detailed description and drawings.
According to the adaptive headlamp for a vehicle according to the embodiment of the present invention, among beam patterns irradiated to the outside by light emitted from a plurality of light sources, beam patterns adjacent to each other are superimposed on a certain region, An effect of preventing cancer stasis can be provided.
Particularly, since adjacent beam patterns overlap each other in a certain area, it is possible to provide a uniform and smooth beam pattern without occurrence of a dark spot between the beam patterns.

The reason for this is that the light guides located on the inboard side are relatively small in width, the beam pattern formed by the light beams passing through the inboard light guide has a large light intensity to increase the light intensity, The guides are relatively large in width, and the beam pattern formed by the light beams passing through the outboard light guide is to increase the width.
In other words, the beam pattern on the inboard side improves the visibility of the driver by improving the brightness, while the beam pattern on the outboard side expands the width of the light instead of reducing the brightness, thereby widening the visibility of the driver to a wider range.
For reference, only one
For example, when the
Further, in the case of a headlamp disposed on the left side relative to the traveling direction of the vehicle, the width of the light guide on the right side may be relatively narrow and the width of the light guide on the left side may be relatively wide.
In this case, the plurality of light guides 310 may be formed to have the same width as the set number of the inboard side, be formed to have the same width as the set number of the outboard side and have different widths, The width of the light guide may gradually increase from the light guide to the outboard light guide.
