In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the gist of the present invention, the detailed description will be omitted. The terms described below are defined in consideration of the functions in the present invention, and may vary depending on the intention or custom of the user or operator. Therefore, the definition should be made based on the contents throughout this specification.

As shown in Figure 1, the shape-variable LED lighting device according to the present invention supports a shape-variable flexible LED strip (hereinafter abbreviated as "strip") 10, the strip 10, and has a shape. The variable shape frame includes a forward and backward frame 20, first and second sockets 30 and 40, and first and second tilting frames 50 and 60.

The strip 10 is a ready-made product in which a plurality of LEDs 12 are mounted on a long flexible strip 11 that is bent by an external force, and lights up when power is applied.

The strip 10 is mounted and illuminated on the front of the shape variable frame 20, 30, 40, 50, 60, and both sides in the longitudinal direction are movable to the first and second strip insertion parts 51, 61, which will be described later. It is preferable that the central portion is inserted and fixed to the forward and backward frame 20 through a piece or adhesive. Even if the center of the strip 10 is fixed to the forward and backward frame 20, it does not interfere with the forward movement of the forward and backward frame 20 and the tilting of the first and second tilting frames 50 and 60, and also prevents the strip 10 from leaving. You can.

The shape variable frames 20, 30, 40, 50, and 60 are coupled to the back of the strip 10 to support the strip 10, and the shape is variable by the forward and backward movement of the forward and backward frame 20, and the first, 2 The shape can be changed by tilting the tilting frames (50, 60), that is, the forward and backward frames (20) can be advanced while the strip (10) is coupled, or the first and second tilting frames (50, 60) can be changed. When tilted, the central part of the strip 10 naturally protrudes more than the left and right sides, and the shape changes so that the left and right sides are inclined.

The forward and backward frame 20 is disposed in the center of the shape variable frame and, based on the drawing, both left and right sides are connected forward and backward to the first and second sockets 30 and 40, and the forward and backward means is, for example, forward and backward. Forward and backward protrusions 21 and 22 formed on both left and right sides of the frame 20, respectively, and forward and backward protrusions 21 and 22 formed on the first and second sockets 30 and 40 are connected to be able to move forward and backward. The forward and backward frame 20, including the guide grooves 31 and 41, moves forward and backward.

The forward and backward projections 21 and 22 and the forward and backward guide grooves 31 and 41 are in the form of a dovetail whose cross-sectional area widens toward the end to prevent separation.

The forward and backward frame 20 moves forward and backward through the user's manipulation. For example, as shown in FIG. 2, it is disposed on the back of the forward and backward frame 20 and has first and second sockets 30 and 40 on both sides in the longitudinal direction. ) includes a fixed rod 23 that is respectively fixed to the fixed rod 23, and a forward knob 24 that is formed on the fixed rod 23 and advances the forward and backward frame 20 by the user's manipulation.

Since the first and second sockets (30, 40) are fixed bodies, the fixing rod (23) can be fixed on both sides to the first and second sockets (30, 40) through bolts or adhesives, and the forward knob (24) A knob accommodating hole 23a may be formed through the accommodating knob.

The forward knob 24 is inserted into the knob receiving hole 23a and is of a cam type in which one end is hinged to the fixed rod 23 and the other free end pushes the forward and backward frame 20 forward.

According to this installation structure of the forward knob 24, the forward and backward frame 20 is not advanced but is inserted into the knob receiving hole 23a while being aligned with the first and second sockets 30 and 40. Therefore, it does not give a sense of heterogeneity.

The forward knob 24 can also be bolted to the fixing rod 23, and the bolt-type forward knob can move the forward and backward frame 20 forward and backward through two-way rotation without using a separate configuration. There is an advantage that the forward and backward frame 20 can be maintained in a forward state and can be advanced to various widths.

The forward and backward frame 20 can be moved backward by returning the forward knob (240) to its original position and then pulling the forward and backward frame 20 back, or by moving the forward and backward frame 20 back and forth to return it to its original position through elastic force. Elastic members may be installed in the frame 20 and the first and second sockets 30 and 40, respectively.

The first and second sockets 30 and 40 have a function of supporting the forward and backward movement of the forward and backward frame 20 and the tilting of the first and second tilting frames 50 and 60, and the forward and backward frame ( 20), it has a plate shape of the same size (width, thickness) and can be freely adjusted in length, and has forward and backward guide grooves 31 and 41 on one side into which the forward and backward protrusions 21 and 22 of the forward and backward frame 20 are respectively inserted. are formed respectively.

As shown in Figure 3, the first and second sockets (30, 40) are equipped with first and second ball joints (32, 42) on the other side as joints for tilting the first and second tilting frames (50, 60). . For example, the first and second ball joints 32 and 42 have housings coupled to first and second sockets 30 and 40, respectively, and balls inserted into the housings are connected to the first and second tilting frames 50 and 60. It is fixed to enable tilting of the first and second tilting frames 50 and 60.

The first and second tilting frames (50, 60) are capable of changing the overall twist shape by twisting both left and right sides of the strip (10), and the first and second tilting frames (50, 60) are configured to change the overall twist shape through the above-described first and second ball joints (32, 42). 2 Twist using the sockets (30, 40) as a reference.

The first and second tilting frames (50, 60) must be configured to maintain the tilted state. For example, the first and second sockets (30, 40) and the first and second tilting frames (50, 60) must be configured to maintain the tilted state. Concave-convex portions (hemispherical protrusions and grooves, respectively) that fit elastically into each other can be formed on opposing surfaces.

The forward and backward frame 20, the first and second sockets 30 and 40 and the first and second tilting frames 50 and 60 must have the strip 10 installed on the front and maintain this state. For this, the first and second tilting frames 50 and 60 must be seated in this state. ,2 First and second strip insertion portions 51 and 61 are formed in the tilting frames 50 and 60.

When the central part of the strip 10 is changed to be convex, and when both the left and right sides are twisted, the strip 10 must not be interfered with. Accordingly, the first and second strip insertions 51 and 61 are the first and second strip insertions 51 and 61, respectively. 2 The ends of the tilting frames 50 and 60 are formed to have a very short length compared to the length of the first and second tilting frames 50 and 60.

In addition, the first and second strip insertion portions 51 and 61 have dovetail-shaped insertion grooves so that the strip 10 can be moved without falling off when both sides of the strip 10 are inserted. It is desirable to protrude forward on the front side of the tilting frames 50 and 60 (upper surface based on the drawing).

The first and second strip insertion parts (51,61) can be fixed types that are formed integrally with the first and second tilting frames (50,60), but after being manufactured as a single piece, they can be connected to the first and second tilting frames (50,60). Alternatively, it may be fixed to the forward and backward frame 20 or the first and second sockets 50 and 60, or alternatively, it may be movably mounted on the first and second tilting frames 50 and 60.

For the movable first and second strip insertion parts 51 and 61, for example, rail grooves are formed along the longitudinal direction at both edges of the first and second tilting frames 50 and 60, and the first and second strips are inserted. The parts 51 and 61 may include a slide part that is slidably fitted into the rail groove while both sides surround the first and second tilting frames 50 and 60.

According to the above structure, the forward and backward frame 20 and the first and second sockets 30 and 40 are connected through forward and backward means, and the first and second sockets 30 and 40 and the first and second tilting frames 50 , 60) are connected by the first and second ball joints 50 and 60 to form an overall assembly, but a fixing wire 70 may be included to provide stability to the assembly and prevent it from falling off more safely.

The fixing wire 70 is inserted into the hole formed in the first tilting frame 50, the first socket 30, the forward and backward frame 20, the second socket 40, and the second tilting frame 60, and has a length of Both ends of the direction are fixed to the first and second tilting frames (50,60) located at both left and right ends, in accordance with the advance of the forward and backward frames (20) and the tilting of the first and second tilting frames (50,60). It must be flexible enough to change shape and is made of a material that can also contract.

The fixing wire 70 is made of a material that only secures the assembly without falling off and does not interfere with the forward movement of the forward and backward frame 20 and the tilting of the first and second tilting frames 50 and 60.

The shape variation of the shape-variable LED lighting device according to the present invention is as follows.

1. Basic shape (see Figure 3).

The first tilting frame 50, the first socket 30, the forward and backward frame 20, the second socket 40, and the second tilting frame 60 are all arranged in a line, and a strip ( 10) illuminates in a flat, straight shape.

2. Strip central convex shape (see Figure 4).

When the forward and backward frame (20) is advanced directly or the forward and backward frame (20) is advanced by turning the forward knob (24), the first and second sockets (30, 40) and the first and second tilting frames (50, 60) are While maintaining the basic shape, only the forward and backward frames 20 are advanced so that the central part of the strip 10 becomes convex, and therefore, the central strip 10-1 is larger than the left and right strips 10-2 and 10-3. It protrudes forward and creates a lighting atmosphere that is different from the basic shape.

When changing the forward and backward frame 20 from the forward state to the basic shape, return the forward and backward knob 24 to its original position and then pull the forward and backward frame 20 back to place it between the first and second sockets 30 and 40. Arrange them in line with these (30 and 40).

3. Twist the strip left and right (see Figure 5).

When twisting the left and right sides of the strip 10 from the basic shape, when the first and second tilting frames 50 and 60 are turned, the first and second sockets 30 and 40 and the forward and backward frames 20 maintain the basic shape. In , only the first and second tilting frames (50, 60) tilt through the first and second ball joints (32, 42).

Accordingly, the center side strip (10-1) illuminates the front, while the left and right strips (10-2, 10-3) illuminate the upper or lower side perpendicular to the front. At this time, the strip 10 passing between the first and second sockets 30 and 40 and the first and second tilting frames 50 and 60 is bent at an angle between right angles, thereby providing a more three-dimensional feeling.

The tilting angles of the first and second tilting frames 50 and 60 are not limited to being perpendicular to the forward and backward frames 20, and various angles are possible.

The central convex shape of the strip and the twist on the left or right side can be combined.

In the present invention, the assemblies of the above configurations (10, 20, 30, 40, 50, 60) can be used alone, or two or more can be connected, for example, the first, facing assembly of neighboring assemblies, 2 Connect the tilting frames (50,60) with couplers.

The coupler can be, for example, a roughly square frame surrounding the periphery of the first and second tilting frames 50 and 60, and a fixing piece fastened to the frame may be added.
