Description
Technical Field
The present invention relates to a lamp body having a 1 st lamp portion and a 2 nd lamp portion arranged around the 1 st lamp portion.
Background
In japanese laid-open patent publication No. 2015-173024, one of the following techniques is disclosed: an LED light source (1 st LED light source) of a 1 st light part is arranged to face the front of the lamp body, and a light source (2 nd LED light source) of a 2 nd light part is arranged to face the rear of the lamp body behind the 1 st LED light source, and light emitted from the 2 nd LED light source is reflected to the front of the lamp body by a reflector.
Disclosure of Invention
In japanese laid-open patent publication No. 2015-173024, the size of the lamp body can be reduced by using the LED light source, but the shape of the reflector that reflects the light emitted from the 2 nd LED light source to the rear of the lamp body to the front is complicated. As a result, the thickness of the lamp body in the front-rear direction (the direction of irradiation of light emitted from the lamp body) increases.
Accordingly, an object of the present invention is to provide a compact lamp body having a 1 st lamp portion and a 2 nd lamp portion that emits light around the 1 st lamp portion.
The present invention is a lamp body having a 1 st lamp portion and a 2 nd lamp portion arranged around the 1 st lamp portion, and having the following features.
The lamp body further includes a substrate disposed inside the lamp body, characterized in claim 1. The 1 st lamp unit has a 1 st LED light source, and the 1 st LED light source is disposed on the substrate and emits light for illuminating the front side of the lamp body. The 2 nd lamp unit has a 2 nd LED light source, and the 2 nd LED light source is disposed on the substrate and emits light for irradiating the periphery of the irradiation range of the 1 st lamp unit in front of the lamp body. In this case, the 1 st LED light source is located forward of a location on the substrate where the 2 nd LED light source is disposed.
The lamp body is characterized in that the substrate extends in a front-rear direction of the lamp body, and the LED light sources are arranged on a surface of the substrate extending in the front-rear direction.
The 1 st lamp unit has a plurality of the 1 st LED light sources, and the 2 nd lamp unit has a plurality of the 2 nd LED light sources. In this case, the 1 st LED light sources emit light directed in different directions from each other, and the 2 nd LED light sources emit light directed in different directions from each other.
A 4 th feature is that, among the 1 st LED light sources, one LED light source is a light source for low beam, the other LED light source is a light source for high beam, and the 1 st LED light sources emit light beams directed in directions opposite to each other.
The 5 th feature is that the 1 st lamp part further includes a 1 st reflector, and the 1 st reflector reflects light emitted from the 1 st LED light source to the front of the lamp body. The 2 nd lamp part further includes a 2 nd reflector, and the 2 nd reflector reflects light emitted from the 2 nd LED light source to the front of the lamp body. In this case, the 1 st reflector is disposed between the 1 st LED light source and the 2 nd LED light source.
A 6 th aspect of the present invention is the lamp according to the 1 st aspect, wherein a front end edge of the 2 nd reflector is located outward of a front end edge of the 1 st reflector in a direction orthogonal to a front-rear direction of the lamp body.
The 7 th feature is that the lamp body has at least two of the substrates. The two substrates are arranged along the front-rear direction so as to face each other in a direction orthogonal to the front-rear direction of the lamp body. The 1 st lamp unit has a plurality of the 1 st LED light sources, and the 2 nd lamp unit has a plurality of the 2 nd LED light sources. In this case, the 1 st LED light source and the 2 nd LED light source are disposed on a side surface of one substrate opposite to the other substrate and a side surface of the other substrate opposite to the one substrate, respectively.
The 8 th aspect is characterized in that the substrate is arranged along a front-rear direction of the lamp body. In this case, the 1 st LED light source and the 2 nd LED light source are arranged on one side surface and/or the other side surface of the substrate extending in the front-rear direction so as to be shifted in the front-rear direction.
According to the 1 st aspect of the present invention, since the 1 st LED light source and the 2 nd LED light source can be arranged on the same substrate without increasing the substrate, the 1 st lighting part and the 2 nd lighting part can be arranged compactly. In a lamp body having a 1 st lamp portion and a 2 nd lamp portion that emits light around the 1 st lamp portion, a compact arrangement of the lamp body can be realized. The 1 st LED light source and the 2 nd LED light source are arranged on the same substrate in a staggered manner. Accordingly, the 1 st and 2 nd lamp parts are separately provided in the lamp body, and functions in the lamp body can be easily distinguished. In addition, the wiring of the 1 st LED light source and the 2 nd LED light source on the substrate is also facilitated.
According to the second aspect of the present invention, the 1 st LED light source and the 2 nd LED light source can be efficiently arranged on the substrate.
According to the 3 rd aspect of the present invention, the irradiation light (the irradiation light from the 1 st lamp unit and the irradiation light from the 2 nd lamp unit) irradiated forward from the lamp body can be made uniform.
According to the 4 th aspect of the present invention, the 1 st lamp portion can be irradiated forward with the low beam irradiation light and the high beam irradiation light. In this way, the function of the 1 st lamp part is spatially divided in the lamp body, whereby a headlamp body having a simple structure can be realized.
According to the 5 th aspect of the present invention, the 1 st reflector is used to divide the interior of the lamp body into the space in which the 1 st LED light source is disposed and the space in which the 2 nd LED light source is disposed, whereby the light from the 1 st LED light source and the light from the 2 nd LED light source can be separately emitted to the front of the lamp body. In addition, since the shape of the reflector can be formed simply, a compact and thin lamp body can be realized.
According to the 6 th aspect of the present invention, light from the 1 st LED light source can be reliably reflected (irradiated) forward by the 1 st reflector, and light from the 2 nd LED light source can be reliably reflected (irradiated) forward by the 2 nd reflector without using a light guide member such as a light guide lens.
According to the 7 th aspect of the present invention, since the two substrates are disposed to face each other with a gap therebetween, the LED light sources can be disposed at the same position in the front-rear direction on the two substrates. Accordingly, the 1 st LED light source and the 2 nd LED light source can be compactly arranged.
According to the 8 th feature of the present invention, the 1 st LED light source and the 2 nd LED light source can be compactly arranged by using both surfaces of one substrate.

Since the structure of the motorcycle 12 is a known structure, detailed description thereof will be omitted.
[ Structure of headlight device 10 ]
Next, the headlight device 10 according to the present embodiment will be described with reference to fig. 1 to 3.
As shown in fig. 1, the rear end portions of a pair of left and right brackets 34 are mounted to the bracket base 28 by two bolts 42. In the side view of fig. 1, the headlamp device 10 has a semicircular (bowl-like) shape and is attached to the front end portions of the pair of left and right brackets 34 by bolts 44. By loosening the bolt 44, the headlight device 10 is moved in the vertical direction (vertical direction), and the optical axis of the headlight device 10 can be adjusted (light adjustment).
A reference line 48 is provided on a side surface of the headlamp device 10, and the position of the headlamp device 10 in the vertical direction can be set as a reference position by moving the headlamp device 10 so that the reference line 48 is horizontal. The reference position is the most common position of the headlamp 10.
As shown in fig. 2 and 3, the headlamp device 10 includes a 1 st lamp portion (1 st lamp portion) 50 and a 2 nd lamp portion (2 nd lamp portion) 52, wherein the 1 st lamp portion (1 st lamp portion) 50 irradiates the front of the headlamp device 10 from the central portion of the headlamp device 10; the 2 nd lamp portion (2 nd lamp portion) 52 is disposed around the 1 st lamp portion 50, and irradiates the periphery (outside) of the irradiation range of the 1 st lamp portion 50 in the front of the headlamp device 10.
Specifically, the headlamp apparatus 10 includes a housing 54 and a lens 56 that constitute a casing of the headlamp apparatus 10. In the side view of fig. 1, the housing 54 has a hemispherical (bowl-like) shape and is fixed to the pair of left and right brackets 34 by the bolts 44. As shown in fig. 2 and 3, the housing 54 is open at the front, and the lens 56 is fitted into the front end portion of the housing 54. The lens 56 is fixed to the distal end portion of the housing 54 by an annular fixing member 58. Accordingly, a space 60 is formed inside the headlamp device 10.
Two substrates (an upper substrate 62 and a lower substrate 64) are disposed in the central portion of the space 60. The upper substrate 62 and the lower substrate 64 are disposed to face each other with a predetermined gap therebetween in the vertical direction, and extend in the front-rear direction and the left-right direction.
On the upper surface 62a of the upper substrate 62 (the surface of the upper substrate 62 opposite to the lower substrate 64), a 1 st LED light source (1 st LED light source) 66a is disposed in a forward position of the central portion, and a 2 nd LED light source (2 nd LED light source) 68a is disposed in a rearward position of the central portion. That is, the 1 st LED light source 66a and the 2 nd LED light source 68a are disposed in the front-rear direction at a predetermined interval on the upper substrate 62, and are disposed on the upper surface 62a so as to emit light upward perpendicular to the upper substrate 62.
Further, on a bottom surface 64b of the lower substrate 64 (a surface of the lower substrate 64 on the opposite side to the upper substrate 62), a 1 st LED light source (1 st LED light source) 66b is disposed at a position forward of the central portion, and a 2 nd LED light source (2 nd LED light source) 68b is disposed at a position rearward of the central portion. That is, on the lower substrate 64, the 1 st LED light source 66b and the 2 nd LED light source 68b are disposed in the front-rear direction with a predetermined interval therebetween, and are disposed on the bottom surface 64b so as to emit light downward perpendicular to the lower substrate 64.
Therefore, the 1 st LED light source 66a of the upper board 62 and the 1 st LED light source 66b of the lower board 64 emit light L1, L2 directed in different directions (directions opposite to each other in the up-down direction), respectively, and on the other hand, the 2 nd LED light source 68a of the upper board 62 and the 2 nd LED light source 68b of the lower board 64 emit light L3 directed in different directions (directions opposite to each other in the up-down direction) from each other. As shown in fig. 3, the 1 st LED light source 66a of the upper substrate 62 and the 1 st LED light source 66b of the lower substrate 64 are arranged at the same position extending in the front-rear direction with an interval in the vertical direction. The 2 nd LED light source 68a of the upper substrate 62 and the 2 nd LED light source 68b of the lower substrate 64 are arranged at the same position extending in the front-rear direction with a space therebetween in the vertical direction.
In the present embodiment, the 1 st LED light source 66a of the upper substrate 62 is an LED light source for low beam, and the 1 st LED light source 66b of the lower substrate 64 is an LED light source for high beam. The 2 nd LED light source 68a of the upper substrate 62 and the 2 nd LED light source 68b of the lower substrate 64 are both LED light sources for a contour light. Also, the 2 nd LED light sources 68a, 68b are LED light sources having a smaller light output than the 1 st LED light sources 66a, 66 b. On the upper substrate 62 and the lower substrate 64, unshown wiring for connecting the 1 st LED light sources 66a, 66b and the 2 nd LED light sources 68a, 68b is arranged.
In the above description, the 1 st LED light sources 66a, 66b and the 2 nd LED light sources 68a, 68b are arranged in the front-rear direction. Although not shown in the drawings, the 1 st LED light sources 66a, 66b and the 2 nd LED light sources 68a, 68b may be arranged in the vehicle width direction (left-right direction).
In the space 60, bowl-shaped 1 st reflector (1 st reflector) 70 and 2 nd reflector (2 nd reflector) 72 are disposed so as to surround the two upper substrate 62 and lower substrate 64.
The 1 st reflector 70 is composed of an upper reflector 72a covering the front portion of the upper substrate 62 from above and a lower reflector 72b covering the front portion of the lower substrate 64 from below. The bowl-shaped 1 st reflector 70 is formed by surrounding the upper and lower reflectors 72a and 72b from above and below by separating the upper substrate 62 and the lower substrate 64 by a predetermined gap (slit extending in the front-rear direction and the left-right direction).
The upper side reflector 72a and the lower side reflector 72b have the same shape. That is, in the cross-sectional view of fig. 3, the upper reflector 72a and the lower reflector 72b have base end portions 74a, 74b and reflecting portions 76a, 76b, respectively, the base end portions 74a, 74b extending in the front-rear direction so as to be parallel to the upper substrate 62 and the lower substrate 64; the reflecting portions 76a, 76b are bowl-shaped and spread (curved) forward from the base end portions 74a, 74 b.
In this case, the reflection portions 76a and 76b are disposed so that the 1 st LED light sources 66a and 66b face the reflection portions 76a and 76b, respectively. Therefore, the 1 st LED light sources 66a and 66b are disposed on the upper substrate 62 and the lower substrate 64 so as to overlap the reflection portions 76a and 76b in the front-rear direction. The front end 78a of the upper reflector 72a and the front end 78b of the lower reflector 72b are positioned forward of the 1 st LED light sources 66a, 66b and the upper and lower substrates 62, 64.
In the front view of fig. 2, the reflecting portions 76a and 76b of the upper reflector 72a and the lower reflector 72b have semicircular shapes. In the cross-sectional view of fig. 3, base end portions 74a and 74b of the upper reflector 72a and the lower reflector 72b are positioned between the 1 st LED light sources 66a and 66b and the 2 nd LED light sources 68a and 68b, and extend in the front-rear direction so as to be parallel to the upper substrate 62 and the lower substrate 64.
The 1 st LED light sources 66a and 66b, the 1 st reflector 70, and the lens 56 are disposed so as to face the 1 st reflector 70, thereby constituting the 1 st lamp unit 50. A partition (not shown) is provided between each base end 74a, 74b and the upper substrate 62 and the lower substrate 64 to partition a space (vestibule chamber) in front of the 1 st lamp unit 50 and a space (vestibule chamber) behind the 2 nd lamp unit 52. The partition portion may be any member as long as it can partition the front and rear chambers between the base end portions 74a and 74b and the upper substrate 62 and the lower substrate 64, such as a vertical wall and a grommet (grommet).
The 2 nd reflector 72 is provided behind the 1 st reflector 70, and is composed of an upper reflector 80a covering the rear portion of the upper substrate 62 from above and a lower reflector 80b covering the rear portion of the lower substrate 64 from below. The bowl-shaped 2 nd reflector 72 is formed by surrounding the upper and lower reflectors 80a and 80b from above and below by separating the upper substrate 62 and the lower substrate 64 by a predetermined gap (slit extending in the front-rear direction and the left-right direction).
The upper reflector 80a and the lower reflector 80b have the same shape, and in the cross-sectional view of fig. 3, have base end portions 82a, 82b and reflecting portions 84a, 84b, respectively, wherein the base end portions 82a, 82b extend in the front-rear direction so as to be parallel to the upper substrate 62 and the lower substrate 64; the reflecting portions 84a, 84b are bowl-shaped and spread (curved) forward from the base end portions 82a, 82 b.
In this case, the reflection portions 84a and 84b are disposed so that the 2 nd LED light sources 68a and 68b face the reflection portions 84a and 84b, respectively. Therefore, the 2 nd LED light sources 68a and 68b are disposed on the upper substrate 62 and the lower substrate 64 so as to overlap the reflection portions 84a and 84b in the front-rear direction. The front end 86a of the upper reflector 80a and the front end 86b of the lower reflector 80b are positioned forward of the 2 nd LED light sources 68a and 68b, respectively.
In the front view of fig. 2, the reflecting portions 84a and 84b of the upper reflector 72a and the lower reflector 72b have semicircular shapes.
The upper reflector 80a of the 2 nd reflector 72 is disposed such that the front end portion 86a of the upper reflector 80a of the 2 nd reflector 72 is positioned above (outside) the front end portion 78a of the upper reflector 72a of the 1 st reflector 70. The lower reflector 80b of the 2 nd reflector 72 is disposed such that the front end 86b of the lower reflector 80b of the 2 nd reflector 72 is located below (outside) the front end 78b of the lower reflector 72b of the 1 st reflector 70.
The 2 nd LED light sources 68a and 68b, the 2 nd reflector 72, and the 2 nd reflector 72 of the lens 56 are opposed to the 2 nd reflector 72 to form the 2 nd lamp unit 52. Further, a knurled portion 88 knurled in an uneven shape is formed on an inner portion of the lens 56 facing the 2 nd reflector 72. Further, as described above, since the base end portions 74a and 74b of the 1 st reflector 70 are disposed between the 1 st LED light sources 66a and 66b and the 2 nd LED light sources 68a and 68b, the 1 st reflector 70 functions as a partition plate for partitioning the 1 st lamp unit 50 and the 2 nd lamp unit 52.
The upper substrate 62, the lower substrate 64, the 1 st reflector 70, and the 2 nd reflector 72 disposed in the space 60 are preferably fixed to the housing 54 by a fixing mechanism not shown.
[ operation of the headlight device 10 ]
In the headlamp device 10 according to the present embodiment configured as described above, when the light L1 is emitted from the upper 1 st LED light source 66a for low beam, the emitted light L1 is reflected forward by the reflection portion 76a of the upper reflector 72a of the 1 st reflector 70. The reflected light L1 is irradiated to the front as the irradiation light L1i of low beam via the lens 56. As described above, in the front view of fig. 2, the reflection portion 76a of the upper reflector 72a has a semicircular shape. Therefore, when the 1 st lamp part 50 irradiates the irradiation light L1i of the low beam emitted from the 1 st LED light source 66a of the upper board 62 forward, as shown in fig. 4, the irradiation light L1i that is positioned inside the upper side of the lens 56 and emits light in a semicircular shape can be visually confirmed when the headlamp apparatus 10 is viewed from the front of the motorcycle 12.
When the light L2 is emitted from the lower 1 st LED light source 66b for high beam, the emitted light L2 is reflected forward by the reflection portion 76b of the lower reflector 72b of the 1 st reflector 70. The reflected light L2 is emitted forward as high beam irradiation light L2i through the lens 56. Since the reflecting portion 76b of the lower reflector 72b has a semicircular shape in the front view of fig. 2, when the 1 st lighting portion 50 irradiates forward the irradiation light L2i of the high beam emitted from the 1 st LED light source 66b of the lower board 64, the irradiation light L2i that is positioned inward of the lower side of the lens 56 and emits light in a semicircular shape can be visually confirmed when the headlamp apparatus 10 is viewed from the front of the motorcycle 12, although not shown.
When the light L3 is emitted from the upper and lower 2 nd LED light sources 68a, 68b for the contour light, the emitted light L3 is reflected forward by the reflecting portions 84a, 84b of the upper reflector 80a and the lower reflector 80b of the 2 nd reflector 72, respectively. In this case, a knurled portion 88 of the lens 56 is formed in front of each of the reflected lights L3. Therefore, the respective lights L3 reflected forward are diffused by the knurling processing portion 88, and the 2 nd lamp portion 52 irradiates the diffused lights L3 forward as the irradiation lights L3i of the positioning beam (position beam). Therefore, as shown in fig. 4, when the headlamp apparatus 10 is viewed from the front of the motorcycle 12, the irradiation light L3i that emits light in an arc shape different from the emission patterns of the high beam and the low beam can be visually recognized at the upper and lower contour portions of the lens 56.
[ modified example of headlight device 10 ]
The headlight device 10 according to the present embodiment may employ the structure of fig. 5 to 7 instead of the structure of fig. 1 to 4. The modification of fig. 5 to 7 is different from the configuration of fig. 1 to 4 in that the 1 st LED light sources 66a and 66b and the 2 nd LED light sources 68a and 68b are respectively disposed on the upper surface 90a and the bottom surface 90b of the single substrate 90.
In this case, as shown in fig. 6, the 1 st LED light source 66a disposed on the upper surface 90a of the substrate 90 and the 1 st LED light source 66b disposed on the bottom surface 90b are disposed so as to be shifted in the front-rear direction. The 2 nd LED light source 68a disposed on the upper surface 90a and the 2 nd LED light source 68b disposed on the bottom surface 90b are disposed so as to be shifted in the front-rear direction. The shapes of the 1 st reflector 70 and the 2 nd reflector 72 are also changed from the configurations of fig. 1 to 4 in accordance with the arrangement positions of the 1 st LED light sources 66a, 66b and the 2 nd LED light sources 68a, 68 b. On the substrate 90, wiring, not shown, for connecting the 1 st LED light sources 66a and 66b and the 2 nd LED light sources 68a and 68b is also arranged.
In this modification, similarly to the configuration of fig. 1 to 4, when the light L1 is emitted from the 1 st LED light source 66a on the upper side for low beam in the front view of fig. 7, the 1 st lighting part 50 emits light in a semicircular shape on the inner side of the upper side of the lens 56. When the light L2 is emitted from the lower 1 st LED light source 66b for high beam, the 1 st lighting part 50 emits light in a semicircular shape inside the lower side of the lens 56. When the light L3 is emitted from each of the 2 nd LED light sources 68a, 68b, the 2 nd lamp light portion 52 emits light in a substantially arc shape at the upper side outline portion and the lower side outline portion of the lens 56.
[ Effect of the present embodiment ]
The effects of the headlamp device 10 according to the present embodiment described above will be described.
In the headlamp device 10, the 1 st LED light sources 66a, 66b and the 2 nd LED light sources 68a, 68b can be arranged on the same substrate (the upper substrate 62, the lower substrate 64, the substrate 90) without increasing the number of substrates. Accordingly, the 1 st lamp portion 50 and the 2 nd lamp portion 52 can be compactly arranged. Therefore, in the headlight device 10 including the 1 st lighting part 50 and the 2 nd lighting part 52 that emits light around the 1 st lighting part 50, the headlight device 10 can be configured compactly. The 1 st LED light sources 66a, 66b and the 2 nd LED light sources 68a, 68b are arranged on the same substrate so as to be shifted back and forth. Accordingly, the 1 st lighting part 50 and the 2 nd lighting part 52 are separately disposed in the space 60 of the headlamp 10, and functions in the headlamp 10 can be easily distinguished. In addition, the 1 st LED light sources 66a, 66b and the 2 nd LED light sources 68a, 68b can be easily wired on the same substrate.
In addition, since the above-described substrate (the upper substrate 62, the lower substrate 64, and the substrate 90) extends in the front-rear direction of the headlamp unit 10, and the 1 st LED light sources 66a, 66b and the 2 nd LED light sources 68a, 68b are arranged on the surface (the upper surfaces 62a, 90a or the bottom surfaces 64b, 90b) of the substrate extending in the front-rear direction, the 1 st LED light sources 66a, 66b and the 2 nd LED light sources 68a, 68b can be efficiently arranged on the substrate.
Further, since the plurality of 1 st LED light sources 66a, 66b emit light L1, L2 directed in different directions from each other, and the plurality of 2 nd LED light sources 68a, 68b emit light L3 directed in different directions from each other, the irradiation lights L1i to L3i irradiated forward from the headlamp device 10 can be uniformized.
Further, since the 1 st LED light sources 66a and 66b emit lights L1 and L2 directed in opposite directions, the 1 st lamp portion 50 can be divided into the low beam irradiation light L1i and the high beam irradiation light L2i and irradiated forward. In this way, the function of the 1 st lighting portion 50 is spatially divided in the headlamp device 10, whereby a headlamp body having a simple structure can be realized.
Further, by dividing the space 60 of the headlamp device 10 into a space in which the 1 st LED light sources 66a, 66b are disposed and a space in which the 2 nd LED light sources 68a, 68b are disposed by using the 1 st reflector 70, the lights L1, L2 from the 1 st LED light sources 66a, 66b and the light L3 from the 2 nd LED light sources 68a, 68b can be emitted to the front of the headlamp device 10 separately. In addition, since the shape of the reflector can be formed simply, a compact and thin lamp body can be realized.
Further, since the distal end portions 86a, 86b of the 2 nd reflector 72 are positioned more outward in the vertical direction than the distal end portions 78a, 78b of the 1 st reflector 70, the 1 st reflector 70 can reliably reflect (irradiate) the light L1, L2 from the 1 st LED light sources 66a, 66b to the front, and the 2 nd reflector 72 can reliably reflect (irradiate) the light L3 from the 2 nd LED light sources 68a, 68b to the front, without using a light guide member such as a light guide lens.
Further, as shown in the configurations of fig. 1 to 3, since the two upper substrates 62 and the lower substrate 64 are disposed to face each other with a gap therebetween, the LED light sources (the 1 st LED light sources 66a, 66b, the 2 nd LED light sources 68a, 68b) can be disposed at the same position in the front-rear direction on the upper substrate 62 and the lower substrate 64. Accordingly, the 1 st LED light sources 66a, 66b and the 2 nd LED light sources 68a, 68b can be arranged compactly.
Further, as shown in the configurations of fig. 5 and 6, since the 1 st LED light sources 66a, 66b and the 2 nd LED light sources 68a, 68b are arranged on the upper surface 90a and the bottom surface 90b of the substrate 90 extending in the front-rear direction so as to be shifted in the front-rear direction on one substrate 90, the 1 st LED light sources 66a, 66b and the 2 nd LED light sources 68a, 68b can be compactly arranged by using both surfaces of one substrate 90.
The present invention has been described above using preferred embodiments, but the technical scope of the present invention is not limited to the scope described in the above embodiments. It will be apparent to those skilled in the art that various changes and modifications can be added to the above-described embodiments. It is apparent from the claims that the embodiments to which such changes or improvements are added can be included in the technical scope of the present invention. In addition, the reference numerals in the drawings attached with parentheses described in the claims are given for easy understanding of the present invention and are not to be construed as limiting the present invention to the elements attached with the reference numerals.
