Description

LED light panel that can be turned on and off without a circuit board and is easily removable

[0001] The present disclosure relates to an LED light panel in which electrodes of different polarities are inserted into the upper and lower surfaces of a panel body, insertion holes are formed by penetrating the upper and lower surfaces in a hexagonal shape so that the electrodes are exposed, and light-emitting elements having first and second connection pins of different lengths are inserted into the insertion holes and then rotated to join them, so that the two connection pins are individually connected to the upper and lower electrodes, respectively.

[0002] A billboard, commonly called a neon sign, is an effective advertising device that bends a vacuum plate to create a specific shape, such as a letter, shape, or number, and then passes an electric current through a vacuum tube to cause the lamp to glow in a specific shape.

[0003] Recently, electronic signboards have been used to express the shapes of letters and other objects using LED lamps, which are more efficient and convenient than neon sign technology.

[0004] As a method for expressing a specific shape on an electric signboard using LED lamps, the traditional method involves connecting electrodes to each other with wires when combining multiple LED lamps on a panel, supplying power to the LED lamps so that they light up, and arranging them in an appropriate shape to express a specific shape.

[0005] However, the traditional method described above is not only very cumbersome and difficult to connect the wires for each LED lamp, but also, in the case of small LED lamps, the wiring is very difficult, so it takes a long time to manufacture the light board, and there are problems such as short circuits easily occurring.

[0006] To solve this problem, there is a technology for an LED light panel that can be lit by inserting an LED lamp into an insertion hole with an electrode inserted without a circuit board. However, although it has the advantage of not requiring a separate bolt when connecting the LED lamp, it has the disadvantage that the insertion hole and the LED lamp are very close together, so a separate tool is required when inserting the LED lamp, and it is also difficult to remove the LED lamp.

[0007] The present disclosure provides an LED light panel having a panel body including an insertion hole formed in a hexagonal shape and a light emitting element in which each of the two connecting pins is individually connected to a different electrode, thereby allowing free attachment and detachment of the light emitting element.

[0008] The purposes of the present disclosure are not limited to those mentioned above, and other purposes and advantages of the present disclosure not mentioned above can be understood through the following description and will be more clearly understood through the embodiments of the present disclosure. Furthermore, it will be readily apparent that the purposes and advantages of the present disclosure can be realized by the means and combinations thereof set forth in the claims.

[0009] According to one embodiment of the present disclosure, an LED light panel has a flat plate shape, an upper electrode intercalated along an upper surface, and a lower electrode intercalated along a lower surface, and includes a panel body having a plurality of insertion holes formed by penetrating the upper and lower surfaces in a hexagonal shape so that the upper electrode and the lower electrode are exposed, a light-emitting element including a light-emitting portion for accommodating a lamp, and a coupling portion for penetrating the insertion hole of the panel body and being coupled to the panel body. The coupling portion includes a first connection pin configured to connect a first terminal of the lamp and the upper electrode, and which is connected to an upper electrode portion of one side of the hexagonal insertion hole without being connected to the lower electrode when the coupling portion is coupled to the insertion hole, and a second connection pin configured to connect a second terminal of the lamp and the lower electrode, and which is connected to a lower electrode portion of one side of the hexagonal insertion hole without being connected to the upper electrode when the coupling portion is coupled to the insertion hole.

[0010] The first connecting pin and the second connecting pin are formed downward based on the upper surface of the coupling portion, and the maximum width formed by the first connecting pin and the second connecting pin with respect to the vertical axis of the coupling portion so that the coupling portion can penetrate the insertion hole is formed shorter than the distance between opposite vertices within a hexagon corresponding to the cross-section of the insertion hole, and the maximum width formed by the first connecting pin and the second connecting pin with respect to the vertical axis of the coupling portion is formed larger than the distance between opposite sides within a hexagon corresponding to the cross-section of the insertion hole, and when the coupling portion is rotated clockwise or counterclockwise based on the vertical axis while penetrating the insertion hole, the coupling portion is coupled to the insertion hole, so that the first connecting pin can be connected to the upper electrode, and the second connecting pin can be connected to the lower electrode.

[0011] In a state where the above-mentioned connecting portion is connected to the insertion hole, at least a portion of the second connecting pin formed downward based on the upper surface may be drawn in so as to be closer to the central axis of the connecting portion, and another portion may be protruded so as to be away from the central axis of the connecting portion, so that the second connecting pin is not connected to the upper electrode but only to the lower electrode.

[0012] The above panel body may include a protrusion on one side of the hexagonal insertion hole and on the other side facing the one side, and the protrusion may be characterized in that it restricts further rotation of the light-emitting element when the connecting portion is connected to the insertion hole.

[0013] The above-mentioned coupling part includes a fastening member formed higher than the lamp in a form that surrounds the lamp, a color cap can be fitted to the fastening member, and when the color cap is fitted to the fastening member, the color cap is formed above the lamp, and light emitted by the lamp can be output by passing through the color cap.

[0014] The LED light panel of the present disclosure can light up a light-emitting element without a circuit board by inserting a light-emitting element so that the connection pin of the light-emitting element is positioned between the vertices of an insertion hole formed in a hexagonal shape, and by rotating the light-emitting element clockwise or counterclockwise to couple the light-emitting element, and the light-emitting element can be conveniently attached and detached.

Furthermore, unless specifically stated otherwise, the statement that a part includes a certain component does not exclude other components, but rather implies that other components may be included.

[0029] FIG. 1 is a drawing for explaining the operation of an LED light panel according to one embodiment of the present disclosure.

[0030] Referring to FIG. 1, the LED light panel may include a panel body (100) and a light emitting element (200) inserted and coupled to the panel body (100).

[0031] The panel body (100) is a flat plate including interpolated positive electrodes with different polarities.

[0032] At this time, the positive electrodes inserted into the panel body (100) can be exposed through a plurality of insertion holes (110) that penetrate the panel body (100) in a hexagonal shape.

[0033] Specifically, the panel body (100) may include an upper electrode intercalated along the upper surface and a lower electrode intercalated along the lower surface, and the intercalated upper electrode and lower electrode may be exposed through an insertion hole (110) that penetrates the upper and lower surfaces in a hexagonal shape.

[0034] At this time, the meaning that the upper electrode and the lower electrode are respectively embedded in the upper and lower surfaces of the panel body (100) encompasses all forms and methods in which the electrodes are formed across both surfaces, and can be implemented in various ways, such as a method in which each electrode plate is attached to the upper and lower surfaces of the panel body (100) and separate front and rear panels are additionally bonded to the outer surfaces of the attached electrode plates to protect the electrodes, a method in which each electrode plate is bonded to the upper and lower surfaces of the panel body (100) and a heat-conducting paint is applied to each surface of the exposed electrode plates to protect the electrodes, and a method in which each electrode plate is attached to the upper and lower surfaces of the panel body (100) and built into a separate support panel so that only the light-emitting element (200) is exposed to the outside, and in the drawings of the present specification, for the convenience of understanding, the upper and lower electrodes are respectively illustrated in a form in which they are exposed to the upper and lower surfaces of the panel body (100).

[0035] At this time, the exposed upper and lower electrodes and electronic components can be connected, thereby forming an electronic panel that does not require additional circuit and wire wiring work.

[0036] In addition, the insertion holes (110) of the panel body (100) can be arranged in a specific shape, so that a plurality of insertion holes (110) can be formed in a shape desired by the user.

[0037] Accordingly, the LED light panel of the above-described embodiment may require only a number of light-emitting elements (200) matching the shape desired by the user.

[0038] According to FIG. 1, the light emitting element (200) can be inserted into the insertion hole (110) of the panel body (100) in a direction facing downward.

[0039] When the inserted light-emitting element (200) is combined, the light-emitting element (200) can be driven by being connected to the exposed electrode.

[0040] At this time, the light emitting element (200) may include a light emitting portion (210) in which a lamp is received and a connecting portion (220) that penetrates the insertion hole (110) of the panel body (100) and is connected to the panel body (100).

[0041] The connecting part (220) may include a first connecting pin (221) and a second connecting pin (222) to connect the terminal of the lamp and the electrode of the panel body (100).

[0042] In this case, the first connecting pin (221) and the second connecting pin (222) can be formed in a downward direction based on the upper surface of the connecting portion (220).

[0043] The first connecting pin (221) is configured to be connected to the first terminal of the lamp and the upper electrode of the panel body (100). The first connecting pin (221) may be connected to the upper electrode portion without being connected to the lower electrode when the connecting portion (220) is connected to the insertion hole (110).

[0044] At this time, the first connection pin (221) may be relatively shorter than the second connection pin (222) so as not to be connected to the lower electrode.

[0045] On the other hand, the second connecting pin (222) is configured to be connected to the second terminal of the lamp and the lower electrode of the panel body (100). The second connecting pin (222) may be connected to the lower electrode, but not to the upper electrode, when the connecting portion is coupled to the insertion hole.

[0046] In this case, in order to prevent the second connecting pin (222) from being connected to the upper electrode, a portion of the second connecting pin (222) may be retracted or protruded. Details are described later in Fig. 2b.

[0047] Here, the lamp may include various types of LED lamps of a known type that include an electric circuit with a lens section mounted thereon, rather than a vacuum tube type LED lamp.

[0048] Additionally, the upper and lower electrodes of the panel body (100) can be individually supplied with (+) and (-) poles converted into direct current power, respectively, and the polarity of the connecting pins can be determined accordingly.

[0049] For example, when the upper electrode is the (+) pole and the lower electrode is the (-) pole, the first connecting pin (221) connected to the upper electrode will be the anode electrode, and the second connecting pin (222) connected to the lower electrode will be the cathode electrode.

[0050] In addition, in the operation of combining the light emitting element (200) with the panel body (100), depending on the maximum width formed by the first connecting pin (221) and the second connecting pin (222), the connecting portion (220) may pass through the hexagonal insertion hole (110) or may be connected to the electrode portion of one side of the insertion hole (110).

[0051] FIG. 2A is a drawing showing a light emitting element inserted in a hexagonal insertion hole in the direction of the vertex according to one embodiment of the present disclosure;

[0052] FIG. 2b is a drawing showing that the inserted connecting portion is rotated according to one embodiment of the present disclosure to connect the connecting pin and the hexagonal one-sided electrode;

[0053] FIG. 3 is a drawing for explaining an operation of combining an inserted light-emitting element according to one embodiment of the present disclosure.

[0054] According to FIG. 3, the direction of the line connecting the first connecting pin (221) and the second connecting pin (222) so that the connecting portion (220) penetrates the insertion hole (110) can be set so that the direction matches the direction of the line drawn by the opposite vertices of the hexagonal cross-section of the insertion hole (110) (①).

[0055] And referring to FIG. 2a, when the maximum width (a) formed by the first connecting pin (221) and the second connecting pin (222) with respect to the vertical axis of the connecting portion (220) is formed to be shorter than the distance (b) between the opposite vertices within the hexagon corresponding to the cross-section of the insertion hole (110) (b>a), the connecting portion (220) of the light-emitting element (200) can penetrate the insertion hole (110).

[0056] At this time, the light emitting element (200) is not connected to the panel body (100), and the first connection pin (221) and the second connection pin (222) are not electrically connected to the upper electrode (121) and the lower electrode (122) exposed through the insertion hole (110).

[0057] On the other hand, if the connecting part (220) is rotated clockwise or counterclockwise with respect to the vertical axis while penetrating the insertion hole (110), the connecting part (220) can be connected to the insertion hole (110).

[0058] Specifically, according to FIGS. 2b and 3, the distance (b) between opposite vertices within a hexagon is longer than the distance (b') between opposite sides.

[0059] Accordingly, when the maximum width (a) described above is formed to be larger than the distance (b') between the opposite sides within the hexagon corresponding to the cross section of the insertion hole (110) and smaller than the distance (b) between the opposite vertices (b>a>b'), the joining part (220) can be joined at one side of the insertion hole (110) as the joining part (220) rotates clockwise (②).

[0060] At this time, the first connection pin (221) and the upper electrode (121) can be connected, and the second connection pin (222) and the lower electrode (122) can be connected.

[0061] In addition, when the coupling part (220) is coupled to the insertion hole (110), at least a portion of the second coupling pin (222) may be inserted so as to be closer to the central axis of the coupling part (220) (e.g., in the direction of the first coupling pin (221)) so as not to be connected to the upper electrode (121), and the other portion may be protruded so as to be farther away from the central axis of the coupling part (220) so as to be connected to the lower electrode (122). Accordingly, the second coupling pin (222) and the upper electrode (121) may be spaced apart from each other so as not to be connected.

[0062] Additionally, the insertion hole (110) may be formed to include a protrusion so that the lower electrode is more exposed than the upper electrode. In this case, the insertion hole (110) may include a configuration in which the protrusion of the lower electrode becomes wider as it approaches one end of the second connecting pin (222) in a downward direction based on the upper surface of the connecting portion (220).

[0063] At this time, at least a portion of the second connecting pin (222) may be bent to come into contact with the protrusion and approach the central axis of the connecting portion (220). Accordingly, the surface area where the second connecting pin (222) and the lower electrode (121) come into contact increases, enabling effective connection.

[0064] In addition, the panel body (100) may additionally include a protrusion configured to prevent the light-emitting element (200) coupled to the insertion hole (110) from further rotating.

[0065] At this time, the protrusion may be included in one side and the opposite side of the hexagonal insertion hole (110).

[0066] Referring to FIG. 3, when additional rotation is applied while the light emitting element (220) is coupled to one side of the insertion hole (110), the coupling portion (220) can be prevented from being loosened by passing through the vertex of the insertion hole (110) by the protrusion (130) included in the insertion hole.

[0067] In another embodiment, the connecting portion (220) and the panel body (100) may be additionally fitted together. In this case, the connecting portion (220) may include a protrusion for fitting together, and the panel body (100) may include a fitting groove corresponding to the protrusion.

[0068] FIG. 4 is a drawing illustrating a fitting connection between a joint and a panel body according to one embodiment of the present disclosure.

[0069] Referring to Fig. 4, the coupling groove (223) may be located on the outside of one side of the insertion hole (110), and the protrusion may be included on the lower surface of the coupling portion (220). In this case, the protrusion may also be positioned on the outside of one side of the hexagonal shape by matching with the coupling groove. When the coupling portion (220) is coupled to the insertion hole (110) in the above-described manner, the protrusion and the coupling groove (223) may be fitted together to restrict further rotation.

[0070] Additionally, a guide groove that becomes deeper as it approaches the coupling groove (223) from the outside of one vertex of the insertion hole (110) may be added. In this case, the direction in which the coupling portion (220) rotates may be determined in one direction, but the protrusion and the coupling groove (223) may be effectively engaged or disengaged through the guide groove.

[0071] Additionally, the light emitting element (200) can be connected to a color cap by a coupling portion (220) so that the light of the output lamp passes through the color cap.

[0072] FIG. 5A is a cross-sectional view illustrating a light-emitting element in which a coupling portion and a color cap are connected according to one embodiment;

[0073] FIG. 5b is a three-dimensional diagram illustrating a light-emitting element in which a connecting portion and a color cap are connected according to one embodiment.

[0074] Referring to FIGS. 5A and 5B, the coupling portion (220) may include a coupling member (224) for coupling with a color cap (510). The coupling member (224) may be formed higher than the lamp in a cylindrical shape in which the outer surface of the coupling portion (220) extends upward and surrounds the lamp inside, and may be coupled in a manner in which the color cap (510) is fitted into the coupling member (224).

[0075] At this time, a color cap (510) is formed above the lamp accommodated in the light-emitting unit (210), so that light emitted by the lamp can pass through the color cap (510) and be output. Through the color cap (510), it is possible to express various colors of the light-emitting element (200).

[0076] Meanwhile, the various embodiments described above may be implemented by combining two or more embodiments as long as they do not conflict or contradict each other.

[0077] Although the preferred embodiments of the present disclosure have been illustrated and described above, the present disclosure is not limited to the specific embodiments described above, and various modifications may be made by a person having ordinary skill in the art to which the present disclosure pertains without departing from the gist of the present disclosure as claimed in the claims, and such modifications should not be understood individually from the technical idea or prospect of the present disclosure.
