At this time, the light emitted from the light source 4 in the upward direction is reflected by the upper reflection surface 2 and proceeds downward, and the light emitted in the downward direction is reflected by the lower reflection surface 3 and the image is reflected. Proceed in the direction. By the way, except that the high beam pattern is formed, the light emitted downward and traveling upward is blocked by the shield 10 so as not to inconvenience other drivers. .

As described above, the projection type headlamp 1 has a shield near one point 6 because the light reflected from the reflecting surfaces 2 and 3 is substantially concentrated at one point 6, unlike the clear type head lamp 1. Even if the shape of (10) is slightly different, various beam irradiation patterns can be formed.

Next, referring to FIGS. 1B and 1C, the shield 10 of the head lamp having the general structure may have a cylindrical shape and correspond to each of the plurality of light distribution patterns in the direction of the rotation axis C of the rotatable body part 11. A plurality of shield protrusions 12, 13, 14, and 15 formed to have a cut-off pattern may be formed in the rotation direction of the body part 11, and cuts of each shield protrusion 12, 13, 14, and 15 may be formed. The -off pattern, that is, the shape of the uppermost surface may be formed differently according to the light distribution pattern.

The plurality of shield protrusions 120, 121, 122, 123, 124, 126, 127, 128, and 129 may be formed in the rotational direction of the body 130, and the shield protrusions 120, 121, 122, The cut-off patterns, that is, the shapes of the uppermost surfaces of the 123, 124, 126, 127, 128, and 129 may be formed differently according to the light distribution pattern. In the embodiment of the present invention has been described for the case of the body portion 130 is made of a cylindrical example, this is only an example for helping the understanding of the present invention is not limited thereto and may be variously changed.

At this time, in the embodiment of the present invention, the plurality of shield protrusions 120, 121, 122, 123, 124, 126, 127, 128, and 129 are respectively the first shield protrusion 120, the second shield protrusion 121, and the first shield protrusion 120. 3 shield protrusion 122, 4th shield protrusion 123, 5th shield protrusion 124, 6th shield protrusion 126, 7th shield protrusion 127, 8th shield protrusion 128, and 9th shield The protrusion 129 may be divided, and in the exemplary embodiment of the present invention, nine shield protrusions are described as an example. However, this is only an example to help understanding of the present invention, and is not limited thereto. The type or number of shield protrusions may be changed depending on the type and number of.

Further, in the embodiment of the present invention, the light distribution pattern formed by the shield protrusions 120, 121, 122, 123, 124, 126, 127, 128, and 129 is a light distribution pattern of a downlight, and the second shield protrusion 121 is formed. ), The third shield protrusion 122, the fourth shield protrusion 123 and the fifth shield protrusion 124 are each one of Class-C. Class-E or Class-V may be formed, and the sixth shield protrusion 126, the seventh shield protrusion 127, the eighth shield protrusion 128, and the ninth shield protrusion 129 may be formed of LHD or RHD, respectively. The other Class-C. It can form Class-E or Class-V.

In this case, at least one of the shield protrusions of the plurality of shield protrusions may be a switching shield protrusion which prevents the abrupt change of the beam pattern when the beam pattern is switched and controls to switch the smooth beam pattern. .

That is, the switching shield protrusion is formed between shield protrusions for forming a predetermined beam pattern, and is formed for the purpose of preventing glare due to sudden beam pattern switching when the beam pattern is switched.

For example, inferring from FIG. 4C, the second shield protrusion 121 is configured as a switching shield protrusion between the first shield protrusion 120 and the third shield protrusion 122 to form the first shield protrusion 120. In the beam pattern switching between the Class-W mode through the Class-V mode through the third shield projection 122, it is possible to induce a smoother beam pattern switching.

Meanwhile, it is possible to implement the Class-C mode and the Class-E mode together using a shield protrusion for Class-C mode among the plurality of shield protrusions, in which case, the Class-E mode is Class-C. Using the shield protrusion for the mode, it is possible to implement by moving the lamp upward.

The second side 131 may form another one of LHD or RHD.

In this case, the Class-V mode is a beam pattern suitable when the vehicle is traveling in an environment where the brightness of the surrounding lights is secured to some extent, such as a city area. In particular, the left / right field of view is wider than the Class-C mode, and the field of view at a somewhat shorter distance (approximately 50 to 60 m in front) is secured than the Class-C mode.

Class-C mode is a beam pattern suitable for vehicles driving on country roads or during normal driving. Compared with a general low beam, it is a pattern in which the amount of light is improved while securing a view of the opposite lane.

Class-E mode is a beam pattern that is suitable when the vehicle is traveling on the highway or on a road that maintains a substantial straight section. Thus, the Class-E mode has a longer forward view than the Class-V mode.

Since the concepts of Class-C, Class-E, and Class-V are obvious in the art, the following detailed description will be omitted, but for reference, Class-C, Class-E, and Class-V, etc. The structure of the shield protrusion for forming a will be described later.

At this time, in the embodiment of the present invention, the light distribution pattern of the high lamp has been described as an example in which the shield protrusion is not formed, but is not limited thereto, and has a predetermined cut-off pattern similar to the plurality of shield protrusions described above. It may be implemented by a shield protrusion.

C. Forming a Class-E or Class-V mode, the sixth shield protrusion 126, the seventh shield protrusion 127, the eighth shield protrusion 128, and the ninth shield protrusion 129 are different from each other of LHD or RHD. One Class-C. Although it is mentioned as forming the Class-E or Class-V mode, the present invention is not limited thereto, and the order of forming the shield protrusions or the light distribution pattern formed by each shield protrusion may be variously changed.

On the other hand, the present invention is characterized by forming a Class-W of the LHD and RHD in the region of the first shield projection 120, that is, the first shield projection and the protrusion of the plurality of shield projections.

Class-W mode is a beam pattern suitable when the vehicle is driving in rainy weather or on wet roads. The far-field forward view is somewhat similar to the Class-E mode, but reduces the reflective glare up to about 10 to 20 meters ahead. In order to, rather, means to reduce the amount of light, which is obvious in the art, detailed description thereof will be omitted below.

4A to 4E, the formation of the Class-W of the LHD and the RHD in the region of the first shield protrusion 120, which is a feature of the present invention, will be described below.

As described above, the shield 100 of the head lamp according to the present invention includes a first shield protrusion 120 formed to have a constant cut-off pattern in the direction of the rotation axis (C) of the rotatable body portion 130 and And a connection part 112 including a first support part 111a and a second support part 111b extending in the vertical direction from the first shield protrusion, and connecting the first support part 111a and the second support part 111b. And a protrusion 113 positioned in a predetermined area of the connection part 112 and protruding from the connection part. In this case, the protrusion 113 may protrude in the direction of the first shield protrusion 120.

Meanwhile, the first shield protrusion 120 may correspond to a shield protrusion for Class-W mode, and the first support portion 111a and the second support portion 111b may be the first shield protrusion 120. That is, although extending from the shield protrusion for the Class-W mode, but not limited to this, it is sufficient to extend from a predetermined area of the body portion 130, in this case, the protrusion 113 is the body portion Can protrude in a direction.

Hereinafter, the first support part 111a and the second support part 111b extend from the first shield protrusion 120, for example.

At this time, the present invention is characterized in that it comprises a predetermined spaced space between the first shield protrusion 120 and the protrusion 113.

That is, the protrusion 113 is fixed to the first shield protrusion 120, but includes a predetermined spaced space between the first shield protrusion 120 and the protrusion 113.

At this time, in the present invention, the protrusion 113 includes a first support 111a and a second support 111b extending in the vertical direction from the first shield protrusion in order to be fixed to the first shield protrusion 120. The protrusion 113 is positioned in a predetermined region of the connection part 112, including a connection part 112 connecting the first support part 111a and the second support part 111b.

That is, as described above in the description of FIGS. 1B and 1C, the head lamp in the general structure may form the Class-W mode through the fourth shield protrusion 15, and thus, the fourth shield protrusion 15 may be used. The Class-W mode may be formed through the fourth shield protrusion protrusion 15a protruding at a predetermined height from the second shield protrusion protrusion 15a. In this case, the space between the fourth shield protrusion 15 and the fourth shield protrusion protrusion 15a is separated. In the end, since the hot spot portion is cut by the fourth shield protrusion protrusion 15a, it is impossible to satisfy the Emax light distribution rule prescribed by the light distribution law.

However, in the present invention, since the protrusion 113 is fixed to the first shield protrusion 120 and includes a predetermined spaced space between the first shield protrusion 120 and the protrusion 113, a hot spot (Hot spot) is not cut by the protrusion 113, and therefore can satisfy the Emax light distribution regulation prescribed by the light distribution regulation.

That is, it means that the amount of light for satisfying the distribution rule of Emax can be irradiated forward through the spaced space between the first shield protrusion 120 and the protrusion 113.

In addition, as described above, the second shield protrusion 121, the third shield protrusion 122, the fourth shield protrusion 123, and the fifth shield protrusion 124 are each Class-C of either LHD or RHD. . Forming a Class-E or Class-V mode, the sixth shield protrusion 126, the seventh shield protrusion 127, the eighth shield protrusion 128, and the ninth shield protrusion 129 are different from each other of LHD or RHD. One Class-C. It can form Class-E or Class-V mode.

In addition, the first side 125 of the body portion in which the plurality of shield protrusions are not formed may form any one of LHD or RHD, and the second side 131 of the body portion in which the plurality of shield protrusions may not be formed may be LHD or The other one of the RHDs may be formed high.

In addition, while satisfying the light distribution law of Emax of Class W, Class-W of LHD and RHD may be formed in the region of the first shield protrusion 120.

Therefore, the shield of the head lamp according to the present invention can simultaneously implement a left driving (LHD) type and a right driving (RHD) type through one shield, and at the same time, the protrusion 113 may be moved to the first shield. It is fixed to the protrusion 120, by including a predetermined spaced space between the first shield protrusion 120 and the protrusion 113, it is possible to satisfy the light distribution law of Emax of Class W.

In other words, a class-W mode that satisfies the light distribution law can be implemented with one shield without additionally forming a separate shield to implement the Class-W mode.

In the following, Class-C. Class-E, Class-V and High beams will be described for the structure of the shield protrusion.

5 is a diagram illustrating various cut-off patterns corresponding to shield protrusions. However, various cut-off patterns corresponding to the shield protrusions are obvious in the art, and are only described for reference in the present invention, and are limited to the structure of the cut-off pattern of the shield protrusions described below in the present invention. It is not.

For example, the third shield protrusion 122 of the cylindrical rotating shield is positioned at the top, thereby forming a beam pattern of the Class-V mode of the LHD.

The pattern p v consists of only horizontal line segments, as shown in FIG. However, in order to indicate the Class-V mode, a wider part should be covered than other patterns (p c and p e ). Therefore, the horizontal line segment in the pattern p v preferably has the same level as that of the upper component of p c or p e . As a result, Class-V mode has a shorter beam irradiation distance than Class-C mode or Class-E mode. This is the same in the left driving (LHD) type and the right driving (RHD) type.

Next, when the cylindrical rotation shield is rotated by a predetermined angle in one direction, the fourth shield protrusion 123 or the fifth shield protrusion 124 is positioned at the top, thereby forming a beam pattern of the LHD Class-C mode.

The cut-off pattern p c when applying the fourth shield protrusion 123 or the fifth shield protrusion 124 is shown in more detail in FIG. 5B. The pattern p c consists of a combination of two horizontal segments (upper segment and lower segment) and segments connecting and connecting them at a predetermined first angle. The two horizontal line segments have a step size t1 in the vertical direction.

Next, when the Class-C mode is implemented by the fourth shield protrusion 123, the cylindrical rotating shield is further rotated by a predetermined angle in one direction so that the fifth shield protrusion 124 is located at the top so that Class-C of the LHD is located at the top. When the E-mode may be formed or the Class-C mode is implemented by the fifth shield protrusion 124, the L-Class forms an LHD by forming the Class-E mode of the LHD by applying the fifth shield protrusion 124 and moving the lamp upward. can do.

The cutoff pattern p e of the fifth shield protrusion 124 is shown in more detail in FIG. 5C. The pattern p e consists of a combination of two horizontal segments (upper segment and lower segment) and segments connecting and connecting them at a predetermined second angle. The two horizontal line segments may have a step of a predetermined size t2 in the vertical direction, and t2 may be smaller than or equal to t1. However, in order to indicate the Class-E mode, the second angle is steeper than the first angle.

In addition, when the cylindrical rotation shield forms the Class-E mode and then rotates further in one direction, the portion where the shield protrusion is not formed is positioned at the top. In this case, as shown in (d) of FIG. 5, since there is no element covering the portion where the light of the projection lamp is concentrated, a high beam pattern may be exhibited.

On the other hand, when the cylindrical rotation shield is rotated by a predetermined angle in the opposite direction of one direction, it is possible to form a beam pattern for the RHD, detailed beam mode pattern for each mode is the same as the LHD, detailed description thereof will be omitted.

Hereinafter, an operation of forming the beam patterns of the Class W mode in the head lamp for the left driving (LHD) and the head lamp for the right driving (RHD) through the left head lamp and the right head lamp will be described with reference to FIG. 6. do.

FIG. 6A is a view showing the positions of the shield protrusions according to the beam pattern of the Class W mode in the LHD headlamps using the shields of the left and right headlamps, and FIG. 6B is a head of the RHD head using the shields of the left and right headlamps. The position of the shield protrusion according to the beam pattern of the Class W mode in the lamp.

However, the positions of the shield protrusions for forming the beam pattern of Class W described below are merely examples, and the present invention is not limited to these positions.

First, referring to FIG. 6A, in order to form a beam pattern of a Class W mode in an LHD headlamp lamp, the left head lamp shield is activated with a shield protrusion of a Class W mode, and the right head lamp shield is formed of an LHD Class E mode. The shield protrusion is activated, and the combination light distribution thereof enables the implementation of a beam pattern of Class W mode.

Next, referring to FIG. 6B, in order to form a beam pattern of a Class W mode in the headlamp lamp for RHD, the left head lamp shield is activated with a shield protrusion of the RHD Class E mode, and the right head lamp shield is a Class W mode. The shield projection of is activated, and the combined light distribution thereof enables the implementation of a beam pattern of Class W mode.

That is, as shown in FIGS. 6A and 6B, through one shield, a headlamp for a vehicle that can be used for both a left driving (LHD) type vehicle and a right driving (RHD) type vehicle can be provided. It is possible to share headlamps.

It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive. The scope of the present invention is defined by the appended claims rather than the foregoing detailed description, and all changes or modifications derived from the meaning and scope of the claims and the equivalents thereof are included in the scope of the present invention Should be interpreted.
