Of course, it provides a characteristic that can create a lighting effect accordingly.

Figure 2 is an exploded perspective view showing a front side structure of the LED assembly according to the invention, Figure 3 is a perspective view showing a back side structure of the LED assembly in the present invention.

The LED assembly 10 of the present invention is provided with an LED lamp 50 to provide a lighting function as well as providing a design that can exert an aesthetic visual effect by its shape and structure itself, and is simply flexible to an LED lamp or an LED module. Compared to a known LED lighting device that connects one power cable, it provides a dynamic lighting function and can be attached to a three-dimensional mounting object smoothly.

Specifically, the LED assembly 10 is composed of a main body 20 having an LED lamp 50 and a cover 30 which is coupled to the main body 20 so as to be openable and closeable.

The main body 20 is composed of a plurality of side wall portions 21 forming a side and a base 22 forming a bottom surface with an open upper portion, and a core shaft 40 vertically standing on the base 22 is formed. It is. The main body 20 shown in the figure consists of an octahedron with an open top, and thus the side wall portion 21 has six sides.

The side wall portion 21 has a first fastening hole 24 formed at each side surface, which is a connector 100 passing through the main body 20 together with the second fastening hole 33 of the cover 30 to be described later. It serves as a through hole. In particular, the first fastening hole 24 has a shape penetrated from an upper end of the side wall portion 21 to a predetermined point (for example, a point adjacent to the lower side than the middle side) in the vertical direction of the side wall portion.

The base 22 forms the bottom surface of the main body 20, and a through hole 23 is formed through the center portion thereof, and the core shaft 40 is coupled thereto.

Although the side wall portion 21 including the base 22 is illustrated as having a planar shape, it is not limited thereto, and may be changed into various three-dimensional structures according to the structure of the object to which the lighting apparatus of the present invention is mounted.

The core shaft 40 is made of various materials, preferably transparent materials, and is made of a hollow cylinder structure to be coupled to the through grooves 23 of the base 22 to stand at a predetermined height toward the inner space of the main body 20. As such, it has a functional feature including an LED lamp 50 that provides an illumination function. Specifically, based on the hollow portion 41, which is hollow inside, the extension portion 42 is formed to further extend a predetermined length to the outside of the main body 20 through the through groove 23 in a state in which the hollow structure is additionally maintained. It includes, and includes the LED lamp 50 in the hollow portion (41).

Since the core shaft 40 has a hollow structure as described above, it is not only easy to include the LED lamp 50 therein, but also can provide a heat dissipation function that radiates heat to the lower side when the LED generates heat. To provide.

The LED lamp 50 is accommodated and supported inside the hollow part 41 by a bracket for supporting the LED lamp or a protrusion provided in the structure of the LED lamp itself, along the hollow part 41 of the core shaft 40. Power and control signals are transmitted through an extended cable 43 (power cable and control cable) to flash and ultimately provide illumination through LED light.

The LED lamp 50 is made of a module type in the COB (Chip On Board) type can be directly coupled to the hollow portion 41 or based on such a simple coupling method, not only having one LED but also having a plurality of LEDs It is possible.

In particular, the control of the LED lamp 50 is made by a controller that can be provided with a separate lighting device according to the present invention, the controller performs a control function for the lighting pattern as well as the blinking of the LED lamp in the plurality of LED assemblies 10. And, this allows a plurality of LED assembly 10 to perform a variety of lighting role.

The extension part 42 of the core shaft 40 has a structure that protrudes a predetermined length outward from the base 22, that is, a structure protruding toward the rear of the LED assembly 10, and serves as a passage through which the power / control cable passes. At the same time, when the LED assembly 10 is spaced apart from a mounting object such as a wall, the LED assembly 10 provides a foundation for bonding / supporting the wall.

In addition, the core shaft 40 has a function of safely binding or supporting the connector 100 to the main body 20, which passes through the internal space of the main body 20 through the first and second fastening holes 24 and 33. The connector 100 is preferably brought into contact with one side of the core shaft 40 so that the plurality of connectors 100 can have a binding force with the main body 20 and thus the core shaft 40 with which the connector 100 contacts. In the present invention, one portion of the) is named as the contact portion 44.

The contact portion 44 is further provided with a binding portion (not shown) having an elastic material ring extending or extending in a strip shape such as a string or a thin wire to close the connector 100. It may be.

It is possible to have a structure () can be opened or collected).

By this binding portion 25, even when the connector 100 passing through the main body 20, the LED assembly 10 flows easily to one side or tightly connected to the main body 20 without loosening the coupling relationship The connector 100 can faithfully perform its original function.

The cover 30 of the present invention performs a function of detachably covering the main body 20. The cover 30 includes a side wall cover 31 and a top cover 32 in a shape corresponding to the main body 20.

The side wall cover 31 has a three-dimensional shape that covers the outer surface of the side wall portion 21 of the main body 20 but has a lower opening, that is, a symmetrical structure with the main body 20. Specifically, the side wall portion 21 The second fastening hole 33 is formed at the same time as having a number corresponding to the side.

The second fastening hole 33 preferably has a shape that penetrates from the lower end of the side wall cover 31 to a predetermined point (for example, a point adjacent to the upper side than the middle side) in the vertical direction of the side wall cover 21. . The shape of the second fastening hole 33 is symmetrical with the first fastening hole 24, that is, when the cover 30 is coupled to the main body 20, the first and second fastening holes 24 and 33 are formed. In this case, the first and second fastening holes 24 and 33 overlapping with each other according to the shape of the first and second fastening holes 24 and 33 are substantially circular or elliptical, so that the connector 100 passes through the second and second fastening holes 24 and 33. While at the same time serves to hold the connector 100. That is, the hole through which the connector 100 passes is formed by the coupling structure of the first and second fastening holes 24 and 33, but the connector 100 is derived by deriving a more stable hole structure when the cover 30 and the main body 20 are coupled to each other. ) To stably guide the extension structure of the connector 100 while avoiding the departure.

The top cover 32 includes an illumination hole 34 formed through the central portion while forming the top surface of the cover 30.

The lighting hole 34 is located above the core axis 40 in which the LED lamp 50 is accommodated, and functions to emit light emitted from the LED lamp 50 to the outside.

Furthermore, the lighting hole 34 can further mount the transparent cover, thereby preventing the light dissipation function while preserving a functioning substance such as rainwater into the LED assembly 10.

Side cover 31 and top cover 32 of the cover 30 is shown as a planar in the drawings, but is not limited to this may be modified to a curved surface or the like according to the structure of the object to which the lighting device of the present invention is mounted. Of course.

Referring again to the operation and function of the lighting device of the present invention having such a configuration as follows.

In the lighting device of the present invention, the LED assembly 10 is composed of one independent structure that exhibits a lighting function, but when a plurality of LED assemblies 10 are combined, stage effects, dynamic screen realization, artistic visual function expression, etc. Can exhibit various visual effects. In particular, the connector 100 having a strong and flexible property is provided with the first and second fastening holes 24 and 33 formed in the side wall portion 21 of the main body 20 and the side cover 31 of the cover 30, respectively. Through connecting the LED assembly 10 through the main body 20 as a result, a plurality of LED assemblies 10 can be freely connected in a matrix structure of up and down / left and right. As a result, a plurality of LED assemblies 10 may cover the entire outer wall of the building or the entire surface of the stage to provide a variety of visual lighting effects in a lighting request place formed of a large area.

In addition, even when the mounting object is not curved or flat, the structure of the plurality of LED assemblies 10 may be bent due to the bendability of the connector 100, and the core shaft 40 may be spaced even when the LED assembly 10 is spaced apart from the mounting object. The extension part 42 of) provides a property that can be in contact with the mounting object.

Figure 4 is a cross-sectional view showing a state in which the filter combination is further mounted to the LED assembly according to the invention.

As mentioned above, the illumination hole 34 formed through the top cover 32 so that the LED light is emitted to the outside can prevent the foreign material from entering the LED assembly 10 by the transparent cover (not shown). It is also possible, but by improving the transparent cover as a filter to be rotated to provide a more diverse dynamic lighting function.

Specifically, FIG. 4 (a) provides a structure in which the filter 60 can be naturally rotated by wind or external force.

Specifically, the filter 60 is exposed to the outside of the illumination hole 34 of the top cover 32, but made of a transparent material or the color portion 61 added a color to a predetermined portion (half or quarter area) Or a diffuser 62 that performs a diffusing function by cutting or processing a specific part to emit an illumination color separate from the LED light or to control the emission of the LED light when the filter 60 is rotated. At the same time, it provides a function to adjust the light divergence angle.

As can be seen from Figure 4 (a), the filter exposed to the outside at a certain height in the top cover 32 preferably has a disk-like structure so that it can be easily rotated by the wind, etc. Similarly, a plurality of wings 63 are formed radially on the outer circumferential surface. The wing 63 may be made of a structure that is additionally protruded from the filter 60, it is also possible to manufacture in a way to cut or cut off one side of the circumference of the filter 60.

In addition, the end of the blade (63) is provided with a rounding processing unit (64) bent in a curvature toward the front end direction (light irradiation direction), so as to rotate more smoothly when the wind blows and at the same time the filter 60 and the cover ( 30) Prevent rainwater from entering the gap easily. Alternatively, a transparent cover separate from the filter 60 may be additionally installed to seal the lighting hole 34 in order to fundamentally block a problem that foreign material flows through the lighting hole.

The filter 60 is coupled to the inner surface of the base 22 via the shaft assembly 70, where the shaft assembly 70 may be coupled within the core shaft 40, but in this case it will cover the LED light. Since there is a possibility that the shaft assembly 70 can stand up from an eccentric point, that is, slightly away from the core shaft 40 as shown in FIG. 4 (a), the filter 60 is provided with a lighting hole 34. Make sure you have an increased volume to cover). That is, the filter 60 does not necessarily have a circular shape such as the illumination hole 34, but may have an elliptical shape or a deformed shape in which one side of the circle is extended / extended.

The shaft assembly 70 consists of a first shaft 71 connected to the filter 60 and a second shaft 72 coupled to stand on the inner side of the base 22 while receiving the first shaft 71. . That is, to ensure the free rotation of the first shaft 71 in a state in which the first shaft 71 is accommodated in the second shaft 72, the first shaft 71 is easily separated from the second shaft 72. The stopper 73 protrudes from one side of the first shaft 71 so as to prevent the dropping, and the one side portion of the second shaft 72 corresponding to the stopper 73 receives the stopper 73. It is also possible to be recessed.

Motor 75 is preferably made of a step motor, it is possible to provide a variety of rotational functions by controlling the number of revolutions / rotational speed, and therefore, when the filter 60 is provided with at least one color portion 61 filter 60 The rotation of) gives the characteristic to exert a variety of lighting effects.

5 is a rear side perspective view showing a modified embodiment of the LED assembly according to the present invention.

Referring to FIG. 5, it can be seen that the supporter 80 is further coupled to the extension 42 protruding outward of the base 22.

The supporter 80 of the present invention may say that the LED assembly 10 is securely coupled to the mounting target when the LED assembly 10 is spaced apart from the mounting target, such as a wall on which the LED assembly 10 is mounted, and the LED assembly 10 is spaced apart. It extends from the extension 42 of the ED assembly 10 and performs a function to contact the mounting target.

The supporter 80 is basically a slightly larger or smaller diameter than the extension portion 42, the connection portion 81 having a structure such as being fitted to the end of the extension portion 42 and the bar extending to a predetermined length (bar) ) And a bracket 83 formed at the end of the bar 82.

The bracket 83 is provided with a fastening hole or a fastening means for fastening, and performs a function of firmly mounting the supporter 80 to a mounting target through fasteners such as bolts fastened thereto. If the mounting target is made of a material such as glass, the bracket 83 may be composed of a suction plate.

This configuration allows the LED assembly 10 to be more securely mounted to the mounting target because the LED assembly 10 can be connected to each other through the supporter 80 even when the LED assembly 10 is spaced apart from the mounting target.

In addition, as can be seen from Figure 5 (b) the supporter 80 is adjustable in length can add convenience.

Specifically, the supporter 80 is composed of a first supporter 84 having a connecting portion 81 coupled with the extension portion 42 and a second supporter 85 having a bracket 83, one of which is a hollow structure. By being made to accommodate the other one, but the contact portion of the two threads (86) is formed can be adjusted in length by the thread combination of the two.

Because of this, even if the LED assembly 10 has a different separation distance from the mounting target, it provides convenience that can be mounted by adjusting the length of the supporter 80.

As described so far, the configuration and operation of a lighting device to which a plurality of LED assemblies according to the present invention are connected are represented in the above descriptions and drawings, but this is merely described, for example, and the spirit of the present invention is not limited to the above descriptions and drawings. And, of course, various changes and modifications are possible within the scope without departing from the spirit of the present invention.
