Referring to FIGS. 3 and 4, the headlamp for a vehicle according to an embodiment of the present invention may include a first lamp module 110 and a second lamp module 120.

The first lamp module 110 generates light in a predetermined light source, and provides light forward along an optical axis. The first lamp module 110 may form a low beam or a high beam according to the light distribution pattern. Further, the low beam and the high beam may be alternately formed in one module dynamically according to the light shielding structure.

The first lamp module 110 may use a light source having a higher light intensity than the second lamp module 120 and the first lamp module 110 may have a larger light emitting area than the second lamp module 120. The detailed structure of the first lamp module 110 will be described later with reference to Fig.

The second lamp module 120 is disposed in front of the first lamp module 110. The second lamp module 120 may generate light forward, for example, a position lamp or a daytime running lamp.

 The second lamp module 120 may be disposed at a predetermined position on the optical axis of the first lamp module 110 and the second lamp module 120 may partially overlap with the first lamp module 110 on the path of light, Lt; / RTI >

Referring to FIG. 3, a first mode in which the second lamp module 120 partially overlaps with the first lamp module 110 is shown.

Referring to FIG. 4, a second mode is shown in which the second lamp module 120 is displaced to a position where it does not overlap with the first lamp module 110.

3, the first lamp module 110 is partially or wholly covered by the second lamp module 120 and is maintained in a state that the first lamp module 110 is not exposed to the outside 4, the second lamp module 120 gradually moves or rotates in a predetermined direction so that the first lamp module 120, which has been hidden by the second lamp module 120, 110) may be displayed.

In the first mode, the first lamp module 110 is off, the second lamp module 120 may be on, and in the second mode, the first and second lamp modules 110, (120) may be in a lighted state.

As such, the first lamp module 110 may be exposed or hidden from the outside, thereby providing dynamic images and aesthetics. For example, the second lamp module 120 may be configured to correspond to the diaphragm of the camera, 1 lamp module 110 is configured to correspond to a camera lens, a vehicle to which the vehicle headlamp according to the present embodiment is applied is provided with a dynamic image Can be implemented.

In the first mode, the second lamp module 120 may be a daytime running lamp (DRL), and in the second mode, the second lamp module 120 may be a position lamp.

Referring to FIG. 5, an exemplary configuration of a first lamp module 110 according to the present embodiment is shown.

The first lamp module 110 includes a first light source 111 and a first reflector 112 for reflecting light generated from the first light source 111 and a second reflector 112 disposed in front of the first light source 111, And a cover member 115 covering the internal structure of the first light source 111 and the like. The first optical shield 113 blocks the incident light, the first lens 114 outputs the incident light to the front, and the cover member 115 covers the internal structure of the first light source 111.

The first light source 111 is a light emitting module for generating light, and may be a projection type light source. Projection-type headlamps have the characteristic of collecting light into one place, which is more advantageous than the general clear type light distribution surface, and can give a sporty aesthetic to the front surface shape of the vehicle. For example, the first light source 111 may be composed of a discharge bulb and a light emitting portion that emits light due to the discharge bulb, and the discharge bulb may be, for example, a metal halide bulb.

The first light source 111 generates predetermined light and provides the generated light to the outside. Although the first light source 111 is shown as having one light source structure, the present invention is not limited thereto, and a plurality of light sources may form one unit to generate light.

The first reflector 112 reflects the light emitted from the first light source 111 and guides light to a desired position. The first reflector 112 may be formed adjacent to the first light source 111 and may have a hemispherical shape as shown in FIG.

The light emitted upward in the light emitted from the first light source 111 is reflected by the inner reflecting surface of the first reflector 112 and travels downward and the light emitted in the downward direction is reflected by the first reflector 112, Reflected on the inner reflection surface of the light guide plate 10 and proceeds upward. The light emitted in the downward direction and traveling in the upward direction may be blocked by the first optical shield 113 so as not to inconvenience other drivers, except for the case of irradiating a high beam.

One end of the first reflector 112 may be adjacent to the first light source 111 and the other end of the first reflector 112 may extend to a position where the other end of the first reflector 112 is in contact with the cover member 115.

In some other embodiments, a diffusive layer or a diffusing layer may be formed on the surface of the first reflector 112. That is, when light is emitted from the first light source 111, the light is irregularly irregularly reflected by the first reflector 112, and the light can be emitted through the first lens 114 forward in a state in which the light is spread evenly. In this case, the light emitted through the first lens 114 can exhibit a uniform distribution of brightness as a whole as in a form emitted from a surface light source. The irregularly-reflecting layer formed on the surface of the first reflector 112 may include repeated irregularities, and the light may be irregularly reflected by the fine irregularities to have a uniform overall brightness.

The first optical shield 113 forms a boundary line or a boundary surface of the light distribution pattern projected forward as described above. A part of the light is blocked by the first optical shield 113, and the remaining light passes through and is refracted by the first lens 114 and directed forward.

At this time, the first optical shield 113 blocks light incident on the first lens 114 beyond a predetermined height, thereby forming a low beam pattern below the cut-off line. The basic light distribution pattern of the low beam may have a light / dark boundary line in which the shape of the end edge of the first optical shield 113 is projected. The contrast boundary line is composed of a horizontal cutoff line, and in the basic light distribution pattern, a high light intensity region (hot zone) can be formed in the vicinity of the cutoff line below the cut-off line.

The structure of the first lamp module 110 is merely an example, and it may have a projection type lamp or a reflector type lamp structure as described above, and an LED lamp structure in which a structure is simplified by employing an LED light source .

6-8, an exemplary configuration and arrangement of the first lamp module 110 and the second lamp module 120 for forming a dynamic image or pattern is shown. As described above, the second lamp module 120 is disposed in front of the first lamp module 110 and is displaced by a predetermined driving means so that it overlaps or overlaps with a part of the first lamp module 110, .

The second lamp module 120 may include one or more line type lamps, wherein the plurality of line type lamps are rotated by a predetermined angle around respective rotation axes, and a plurality of line type lamps And may be set to one of a first mode in which the lamp module 110 partially overlaps or a second mode in which the first lamp module 110 and the first lamp module 110 do not overlap.

Referring to FIG. 6, a plurality of line type lamps may have a bent portion bent at a predetermined angle, and each line type lamp forms a predetermined angle about a bent portion. In a first mode in which a plurality of line-type lamps partially overlap with the first lamp module 110 on the path of light, the opposite end of the rotation axis of the plurality of line-type lamps, as shown in FIG. 6, (Not shown).

8, when a plurality of line type lamps are set to the second mode, they can be continuously arranged in a shape close to a circle along the outer periphery of the first lamp module 110. [ For this purpose, as the number of the plurality of line type lamps increases, the predetermined angle of the bent portion of each line type lamp increases, so that it can have a shape close to a straight line. When the head lamp is viewed from the front, the rotation axes of the plurality of line type lamps are arranged on the outer side of the first lamp module 110 on the plane, and the plurality of line type lamps are rotated along the rotation axis to be set to the second mode The second lamp module 120 and the first lamp module 110 may not be overlapped on a plane.

Referring to FIG. 7, a plurality of line type lamps can rotate in the same direction (counterclockwise in the drawing), and a plurality of line type lamps can rotate at the same time.

Referring to FIG. 8, a plurality of line type lamps constituting the second lamp module 120 are arranged in a second mode, that is, a position where they do not overlap with the first lamp module 110. Since the rotation axis of the plurality of line type lamps is located outside the first lamp module 110, the first lamp module 110 and the second lamp module 120 can be maintained in a state in which they do not overlap with each other.

When the plurality of line type lamps constituting the second lamp module 120 are in the second mode, the opposite ends of the rotation axis of the plurality of line type lamps move in the central portion of the first lamp module 110 in the initial position, And may be aligned to face the rotation axis of the line type lamp. That is, the plurality of line-type lamps are arranged in a manner to surround the first lamp module 110, and one end and the other end of the line-type lamps aligned in the same direction may face each other.

When the plurality of line type lamps constituting the second lamp module 120 are in the second mode, the first lamp module 110 may be disposed inside the plurality of line type lamps.

Each of the rotation axes of the line type lamp may be formed of a material capable of moving from one end to the other end of the optical cable or light through which the light travels. The light incident through one end of the rotation axis is transmitted to the main body of the plurality of line type lamps , And a line type lamp may emit light. However, the present invention is not limited thereto, and a plurality of optical elements may be provided in the line type lamp to emit light by themselves. In this case, the second lamp module 120 may include a plurality of optical elements provided in series on a circuit board, and an inner lens and a light guide may be further provided in front of the optical element. For example, an LED may be used as the light emitting element. A plurality of optical elements can be arranged in a line to form a predetermined light distribution pattern. The plurality of optical elements may be disposed on the same circuit board, and the circuit board may be a band type extending to one side and may be a flexible substrate.

A plurality of optical elements may be disposed on a circuit board, and an inner lens may be disposed in a manner to surround each optical element and the circuit board. The inner lens may serve to guide light generated from a plurality of optical elements forward.

In addition, a light guide may be additionally provided in front of the inner lens, and the light guide may function to condense or diffuse light to form a predetermined light pattern.

In some other embodiments, the configuration of one of the inner lens or the light guide may be omitted.

Further, in some other embodiments, a plurality of optical elements may be disposed outside a plurality of line-type lamps, and each of the plurality of line-type lamps may include a light guide for guiding light. A plurality of optical elements that are light sources for supplying light to the light guide can be provided at one or both ends of the light guide to provide light from the optical element to the light guide.

In addition, according to the first mode and the second mode, optical elements of different colors may be disposed at one end (for example, a rotation axis) of the position where the plurality of line type lamps are disposed, The color of the second lamp module 120 in the first mode and the color of the second lamp module 120 in the second mode may be set to be different from each other.

At this time, when the plurality of line type lamps are changed to the first mode or the second mode, light can be supplied by the optical element provided adjacent to the rotation axis whose position is not changed, Uniform light can be supplied from the optical element to the plurality of line type lamps irrespective of the two modes.

For example, a first optical element for generating white light or orange light may be disposed at one end of a plurality of line type lamps in the first mode state, and the second lamp module 120 may be a Daytime Running Lamp (DRL) White light or orange light can be irradiated forward to perform the function.

On the other hand, in the second mode, a second optical element for generating white light or orange light is disposed at one end of a plurality of line type lamps, or the second optical module is set so that the light emission color of the first optical element is changed, The white light or the orange light can be irradiated forward to perform the positioning lamp function. That is, in this case, the first optical element and the second optical element may have the same configuration and may be configured such that the luminescent colors are set different from each other.

Such a color arrangement may vary depending on the use of the lamp, in which case the first optical element and / or the second optical element can be fixed in position. Also, other colors other than the white light or orange light described above may be used.

Each of the light guides can guide light incident from one side or both sides to control light so as to uniformly emit light from a plurality of line type lamps.
