FIG. 2 is a perspective view of an optical output apparatus 100 according to an embodiment of the present invention, and FIG. 3 is an exploded perspective view of an optical output apparatus 100 according to an embodiment of the present invention. FIG. 4 is a diagram illustrating an emission pattern of a conventional optical output apparatus and an emission pattern of an optical output apparatus according to an embodiment of the present invention.

The optical output device 100 can be manufactured in various sizes, materials, and shapes, such as a door catch, a cup holder, and a plate. In the various embodiments of the present invention, door scuffs and door catches are illustrated or shown as examples of the optical output apparatus 100, but the present invention is not limited thereto.

As shown in FIGS. 2 and 3, the optical output apparatus 100 may be realized by coupling the upper plate 110, the middle plate 120, and the lower plate 130 together.

The lower plate 110 supports the middle plate 120 and the upper plate 130, and the light emitting module 140 is inserted or provided to diverge or reflect the light source. The lower plate 110 may be fabricated in various shapes and sizes, and may be formed of a light-transmitting material such as a light diffusion polycarbonate (PC). The light diffusing PC may be a light diffusing PC 85, a light diffusing PC 80, a light diffusing PC 70 or the like, but is not limited thereto.

The lower plate 110 is formed with a seating groove 115 into which the light emitting module 140 is inserted. When the optical output device 100 is implemented as a plate having a predetermined length, the seating groove 115 may be formed by a grooving method in the longitudinal direction along the longest side, but the present invention is not limited thereto. When the optical output apparatus 100 has a curved surface or a circumference according to various embodiments, the seating groove 115 may be formed into a curved surface having a certain R value or a cylindrical shape having a predetermined diameter according to the shape of the optical output apparatus 100 .

According to one embodiment, the seating groove 115 is formed to have a smaller size than the light emitting module 140, that is, a length less than a predetermined threshold value, so that the light emitting module can be seated and a stable clearance is provided So that the light emitting module can be protected from an external impact.

One surface (e.g., lower surface) of the lower plate 110 may be finished by printing or coating a common sheet, but according to one embodiment, a reflective member (e.g., reflective sheet) may be attached. When the reflective member is attached, the diffusing power of the light emitted from the light emitting module 140 is improved, and the configuration of the reflective sheet can be applied regardless of the optical output device 100 according to any form of the present invention .

The middle plate 120 is coupled to the upper portion of the lower plate 110, and a protrusion 125 including an output area printed with a character / logo or the like is formed. The output area allows the light emitted from the light emitting module 140 provided in the lower plate 110 to be selectively transmitted to the outside, thereby outputting a content desired by the user. For example, the characters or logos included in the output area of the protrusion 125 may be printed / ripped so that the light is transmitted, and the remaining color may be printed or coated on the outer surface. Such a middle plate 120 can be manufactured in various shapes and sizes, and can be formed of a material having a light transmitting property (e.g., acrylic, light diffusion PC, etc.) like the lower plate.

' 형태로 구현됨으로써 후술할 상판(130)의 관통부(131)와 더욱 밀착되어 결합이 가능하다. 이에 의해, 광출력장치(100)의 상부에 물이 떨어지게 되더라도 내부에 물이 유입되는 것을 최소화할 수 있다. According to one embodiment, the protrusion 125 of the middle plate 120 may be configured to protrude upward. The projecting portion 125 may be formed by machining an acrylic or light diffusing PC by machining (CNC, MCT, etc.) or laser processing the remaining portion except for the projecting portion 125. As described above,

So that it can be more closely attached to the penetration portion 131 of the upper plate 130 to be described later. Accordingly, even if the water drops on the upper part of the optical output apparatus 100, the inflow of water into the inside can be minimized.

The upper plate 130 is coupled to the upper portion of the middle plate 120 and is made of a relatively hard metal such as stainless steel to protect the optical output device 100 from an external impact.

According to one embodiment, a penetrating portion 131 is provided in a part of the top plate 130 (for example, substantially at the center). The projecting portion 125 of the middle plate 120 can be fitted to the upper plate 130 through the penetration portion 131.

According to one embodiment, the reflection restricting portion 135 may be formed in a part of the frame of the upper plate 130. The reflection restricting unit 135 refers to a separate area having a specific thickness and length in the frame and is provided on the upper surface of the light emitting module 140 to prevent light reflected from the light emitting module 140 of the lower plate 110 from being directly exposed on the plane. And may be formed to have an area equal to or wider than the light emitting portion. For example, the reflection restricting part 135 may include a first reflection restricting part 135_1 having a first area size and a second reflection restricting part 135_2 having a second area different from the first area. have. In this case, the first reflection restricting part 135_1 may be formed as a frame at a position corresponding to the position where the light emitting module 140 is seated, and wider than the second reflection restricting part 135_2.

3, the mounting portion 115 is biased to one side so that the light emitting module 140 is also biased toward one side of the lower plate 110. [ Light is emitted from the light emitting portion of the light emitting module 140 toward the upper side of the optical output device 100 toward the middle plate 120 and both the lower plate 110 and the middle plate 120 are made of a light transmitting material, Unintentional noise light is exposed if the reflection restricting portion 135_1 of the light guide 130 is not provided or formed with an insufficient area. Such a noise light may be a pattern in which a pattern (e.g., a circle, an ellipse, a polygon, or the like) of a light emitting element (e.g., an LED element) of the light emitting portion itself is exposed when the light emitting device 100 is viewed from above have. That is, in order to prevent light from being reflected in an unintended specific area other than the light emitted from a character or logo printed or formed on the protrusion 125, or to prevent a specific pattern due to the light bulb of the optical element from appearing on the character or logo, And a restriction unit 135_1.

This noise light phenomenon is illustrated in FIG. Specifically, FIG. 4A shows the light emission pattern of the conventional optical output apparatus 100. FIG. In the related art, since the light emitting module is positioned at the center of the optical output device 100 or at the center, the noise light P due to the light bulb is emitted to the logo portion as the light reflection target located at the center . That is, problems such as a dot effect or diffuse reflection by a light bulb have been caused. However, according to the embodiment of the present invention as shown in FIG. 4B, the light emitting module 140 is biased to one side to illuminate the middle plate 120, and the corresponding light emitting module 140 is mounted on the reflection limiting part 135_1 So that the light does not leak out to the outside. Therefore, the user can see that a clearer and clearer light is emitted.

Also, it is possible to minimize the phenomenon that light leaks out or diffuses from the edge of the optical output device 100 through the entire frame of the upper plate 130 as described above.

2 and 3, the reflection restricting portion 135_1 is formed such that the lengths of both frames of the upper plate 130 are different from each other. However, the present invention is not limited thereto, It is also possible that the length, thickness, and area viewed on the substrate are the same (i.e., symmetrical).

The light emitting module 140 may include a light emitting element (e.g., an LED), a controller (e.g., a micro control unit, MCU) for controlling the light emitting module 140, and a circuit connecting the light emitting element and the controller. A surface including a region in which light emitting elements are continuously generated at predetermined intervals from both sides of the light emitting module 140 is referred to as a light emitting portion.

According to one embodiment, the light emitting module 140 may be provided in a bar shape which can be cut by a predetermined unit. The light emitting module 140 may be implemented as an LED plate that is finished with an epoxy or a tube so that the light emitting module 140 can be self-waterproofed. When the light emitting module 140 includes an LED element, the LED element may be implemented in a single color, RGB, NEO PIXEL, or the like, but is not limited thereto.

According to one embodiment, the light emitting module 140 can control the light emitting mode by the remote controller. The luminescent pattern may include, but is not limited to, a blanking scheme in which light can be flickered, or a moving scheme in which an LED element is lit / turned on in a cascade manner.

In Fig. 3, the first plate, the second plate and the third plate can be combined in various ways. For example, the first plate, the second plate, and the third plate may be attached with a double-sided tape or may be bonded through a sealing process (e.g., silicon or the like).

According to one embodiment, a magnetic substance may be inserted into at least one of the lower plate 110, the middle plate 120, or the upper plate 130 to be magnetically coupled. For example, at least one of the lower plate 110, the middle plate 120, and the upper plate 130 may have a groove into which a magnet can be inserted, respectively, and a magnetic body (e.g., a magnet) may be provided in each groove. Such a magnet system has an advantage that no double-sided tape or adhesive residue is generated when the optical output apparatus 100 is removed or disassembled.

'형태로 구현되는 것이 가능하다. Although not shown, according to one embodiment, a drain hole may be formed in at least one of the lower plate 110 and the middle plate 120. Such a drain hole may be formed to allow the moisture to escape when fine moisture enters the inside of the optical output device 100 despite the strong coupling between the top plate 130 and the middle plate 120. In this case, at least one of the lower plate 110 and the middle plate 120 may be formed in a tapered shape in which the area becomes narrower toward the lower side in order to maximize the drainage effect. For example, at least one of the lower plate 110 or the middle plate 120 may have a roughly "

Although not shown, according to an embodiment, when the optical output apparatus 100 is implemented as a door scuff, it is possible that the door of the vehicle is physically driven as the door is opened or closed. For example, the optical output apparatus 100 is connected to a drive means (e.g., a pulley or the like) for raising the optical output apparatus 100 in an inclined state in a state where the optical output apparatus 100 is horizontally positioned, The driving unit can lift one side of the optical output device 100 when the vehicle door is opened.

As another example, when an elastic body such as a spring is provided as a driving means in one region of the optical output apparatus 100 and the driving means compresses the elastic body to have a restoring force in a state where the vehicle door is closed, At least one region of the optical output apparatus 100 can be raised by the restoring elastic force while the pressing of the driving means for pressing the elastic body is released.

On the contrary, when the door is closed, the driving means can be compressed again so that the driving means can lower the optical output apparatus 100 or have a restoring force. According to this embodiment, the user can have a more dynamic feeling as the door is opened and closed, and the beauty and personality of the optical output device 100 can be exhibited.

According to one embodiment, the optical output device 100 can be subjected to a primary waterproof treatment by a coupling method of the penetrating portion 135 of the upper plate 130 and the protruding portion 125 of the middle plate 120, The second waterproofing process can be performed by the molding part 150 surrounding the rim of the lower plate 110, the middle plate 120, and the upper plate 130. According to a further embodiment, the molding part 150 is formed so as to be lowered toward the outside, so that the water is allowed to flow out naturally along the outer inclined surface of the molding part 150, thereby enabling a third waterproof treatment.

3 and 5, the optical output device 100 may be formed of a combination of at least one of a lower plate 110, a middle plate 120, and a top plate 130 It is possible. If the upper plate 130 is excluded from the configuration of the optical output apparatus 100, the protrusion 125 of the middle plate 120 is omitted, and the shape of the middle plate 120 including the output area in which characters and a logo are printed . In this case, the upper surface of the middle plate 120 is coated (for example, hard coated) to protect the optical output device 100 from an external impact. However, the present invention is not limited thereto, and the upper surface of the middle plate 120 can also be coated with the three-layer structure.

(For example, coating) of the respective components of the optical output apparatus 100 or the optical output apparatus 100 disclosed in Figs. 2 and 3, the coupling method of each plate, the drain hole, the driving method : Spring, pulley, etc.) can be similarly applied to various types of optical output devices 100 to be described in the following drawings. In other words, the various embodiments of the optical output device 100 may be implemented with a common configuration and function except for portions referred to as differences in this document.

5 is an exploded perspective view of an optical output apparatus 100 according to another embodiment of the present invention.

3, the optical output apparatus 100 of FIG. 5 differs from the optical output apparatus 100 of FIG. 3 in that the lower plate 110 is positioned so that the seating groove 115 of the lower plate 110 is coupled to the middle plate 120 110 and the middle plate 120 are combined. Further, the light emitting portion of the light emitting module 140 is coupled to the seating groove 1150 so as to emit light in a direction opposite to the surface coupled with the middle plate 120.

In this case, the light emitting module 140 is not directly emitted toward the upper side (the middle plate direction), but is emitted toward the lower side of the optical output device 100 to generate an indirect lighting effect. Therefore, no noise light is generated by the light emitting device when the optical output device 100 is viewed from above the optical output device 100 without depending on the reflection restricting portion 135 of the upper plate 130. [

The light emitting portion of the light emitting module 140 emits light toward the other surface than the surface on which the mounting groove 115 of the lower plate 110 is formed and thus emits light toward the surface on which the mounting groove 115 is formed The light is emitted in a relatively larger area than that of the light source, and the lightness of the light can be improved. In this case, as described above, a reflection member is attached to the bottom surface of the lower plate 110, that is, the surface opposite to the surface on which the seating groove 115 is formed, thereby maximizing the reflection effect of light.

When the bottom plate 110, the middle plate 120 and the light emitting module 140 of FIG. 5 are combined with the optical output device 100 of the two-layer structure using the bottom plate 110 and the middle plate 120 Likewise applicable.

6 is an exemplary view showing a direction in which a conventional light emitting module is inserted and a difference between directions in which the light emitting module 140 is inserted according to various embodiments of the present invention.

6 (a) is a view of the conventional optical output apparatus 100 in which the light emitting module E is inserted into a plate. In this case, since the light emitting module E emits light toward the side direction (a), not the top / bottom of the plate, it emits light toward the upward direction (b) or the downward direction (c) The area where the light is reflected from the plate relatively becomes narrower. In addition, since the light emitting module E is designed so as to face toward the center under the premise that the logo part to be a light reflection target is located at the center of the plate, the noise light effect as shown in FIG.

Accordingly, in the various embodiments of the present invention, the lower plate 110 and the light emitting module 140 are designed in the manner of (b) or (c) of FIG. 6, so that clear light emission as shown in FIG. More specifically, in the above-described combining method of FIG. 3 and FIG. 5, both methods (c) are adopted. In FIG. 5, (c) is adopted, but the lower plate 110 is reversed to be coupled with the middle plate 120 in comparison with FIG. Although not shown in this document, the method of FIG. 6 (b) can also be adopted in some configurations of the optical output apparatus 100.

6 (b) and 6 (c), the direction of the light emitting module 140 is set only in the vertical direction. However, according to one embodiment, the light emitting portion of the light emitting module 140 is light- May be coupled to the seat portion 115 to be discharged. For example, the mounting portion 115 may be formed with a slant support portion (not shown) so that the mounting portion 115 can be tilted at a predetermined angle when the light emitting module 140 is inserted. The inclined support portion may be formed such that a specific region is formed higher in the mount portion 115. However, the means for adjusting the inclination of the mount of the light emitting module 140 is not limited to the inclined support portion. The light emitting part of the light emitting module 140 is positioned to emit light at a predetermined angle so that the light emitting light diffuses into the inside of the optical output device 100 and a clearer light output effect can be obtained.

7 is a perspective view of an optical output apparatus 100 having two light emitting modules 140 according to various embodiments of the present invention. The optical output apparatus 100 of FIG. 7 is applied to a rear column (two columns) (A) and the rear surface (b) of the door scuff that can be used. The light emitting module 140 in the front surface a of the optical output device 100 is invisible from the outside and thus the optical output device 100 may include at least two or more light emitting modules 140. [

Figure 8 is a perspective view of an optical output device implemented in a different form from Figure 2, in accordance with various embodiments of the present invention. The optical output device 100 of Fig. 8 is an example of a door catch that can be applied to a handle portion of a vehicle door. As described above, the optical output device 100 can have various shapes and sizes, and can be applied to any article provided in a vehicle.

Hereinafter, the manufacturing steps of the optical output device 100 of FIGS. 1 to 8 described above will be described with reference to FIG. 9 is a flowchart showing a manufacturing method of the optical output device 100 according to an embodiment of the present invention. It is also possible that at least some of the steps in FIG. 9 are mutually reversed or omitted, and that a separate process is added between the steps.

According to various embodiments of the present invention, the lower plate 110 and the seating groove 115 may be formed (S910). The lower plate 110 is formed, for example, by cutting a light diffusion PC to a predetermined size to form a body (body) with a specific shape (for example, a plate), and a seating groove 115 is formed by a grooving process. In this case, at least two grooving processes may be added depending on the use of the optical output apparatus 100. [ The material of the lower plate 110 and the shape of the plate and the like are arbitrary examples, but the present invention is not limited thereto.

In addition, the seating groove 115 may be larger than the size of the light emitting module 140 by an error less than a predetermined value, so that the light emitting module 140 can be fixed. Such grooving is not limited to a specific direction, size and shape, and can be processed into various sizes and shapes as required.

Next, the middle plate 120 and the protrusion 125 may be formed (S930). The intermediate plate 110 may also be formed by cutting a light diffusion PC, acrylic or the like to a predetermined size to form a body in a specific shape, and the protrusion 125 may be formed through machining or laser processing. According to various embodiments, the middle plate 120 may be implemented as transparent or opaque, and the opaque manner may be processed by a variety of printing methods. In this case, opaqueness can be various forms such as gold, silver or pearl. Further, the intermediate plate 120 may be formed with a layer (e.g., hard coating, UV coating, etc.) layer as the case may be.

In addition, an output region including characters, logos, and the like to be displayed through the light source may be formed in the protrusion 125. [ Such an output region can be formed by a wave (intaglio) method. For example, the output area can be formed by exposing a region corresponding to the shape of a character, a logo, or the like, with respect to the middle plate 120 printed with the opaque color on its surface, so that the transparent region of the output region can be exposed, Only the corresponding letter or logo can be displayed on the outside by the light source. However, the present invention is not limited thereto. Alternatively, the output region may be expressed using a sheet or the like, and in some cases, only the output region may be formed without the protrusion 125 being formed.

Next, the upper plate 130 and the through holes 131 may be formed (S950). In the upper plate, stainless steel or the like, which is a light-transmitting material, is cut to a predetermined size to form a body in a specific shape, and a through hole 131 is formed through processing. In this case, the size and area of the reflection restricting portion 135, which is a frame region of the through hole 131, can be set and processed.

In the preparing process of each plate, a drain hole forming process, a magnetic material inserting process, or the like may be added as necessary, and the structure of each plate may be modified and processed accordingly.

When the preparation process of each plate is completed, a bonding process of joining the plates is performed (S970). Such bonding processes can be of various types, such as double-sided tape, sealing (e.g., silicon), or magnetic coupling. Then, the waterproofing treatment of the combined components and the molding process for finishing the appearance of the rim are carried out. In this case, the molding part is formed so as to be lowered in height toward the outside, so that water or the like can be guided to flow along the external inclined surface.
