The casing (1) is a “└” type primary panel (2), a “┘” type secondary panel (4), and an upper panel connecting the primary panel (2) and the secondary panel (4). 6) is assembled. The material of the casing 1 is preferably elastic plastic, silicone, or a mixture thereof that is resistant to heat and impact, and elasticity and strength can be appropriately adjusted by adding a plasticizer. It is also possible to mold the casing 1 into a thin metal plate made of aluminum or copper as long as it can adequately give elasticity.

The primary, secondary and upper panels 2, 4, 6 are made of thin sheets to have sufficient elasticity to elastically deform from side to side. The above-described LED bar 1'light emitting module is accommodated in the space S.

The primary panel 2 includes a primary lower panel 20 extending horizontally from the bottom and a primary side panel 22 vertically standing at one side of the primary lower panel 20. Unless otherwise specified in the specification of the present invention, "one side" refers to the left part of FIG. 2 and "the other side" refers to the right part of FIG. 2. One side guide 24, which is a thick part, is formed by attaching flesh to the intersection of the primary lower and side panels 20 and 22, and a circular concave groove opened upward on the upper part of the one guide 24 (12) to form. The other side guide 26 is formed at an end of the primary lower panel 20 opposite to the one side guide 24, and a circular concave groove 12a opened upward is formed on the upper side of the other side guide 26.

The secondary panel 4 has a secondary lower panel 42 that extends horizontally from the bottom to face the primary lower panel 20, and a primary side panel 42 standing vertically at the other side of the secondary lower panel 20. It consists of a secondary side panel 40 facing the 22). The secondary side panel 40 extends long enough to cover the other side guide 26 from the side. On both ends of the secondary lower panel 42, circular one side protrusion 46 and the other side protrusion 46a are formed at positions vertically opposite to the concave grooves 12 and 12a of the primary lower panel 20, respectively. As described above, the primary panel 2 and the secondary panel 4 are assembled by each protrusion being fastened to each guide. The concave grooves 12 and 12a corresponding to the one and the other protrusions 46 and 46a do not need to be closely assembled without tolerance, and it is desirable to have a structure that can move left and right with a slight gap.

3A is a plan view viewed from above by separating only the primary panel 2. The primary lower panel 20 of the primary panel 2 is not an entirely rectangular closed panel, but has a flap shape extending from the primary side panel 22 periodically with a space 2A interposed therebetween, The primary side panel 22 Therefore, the concave groove 12 is continuously formed along the entire length direction of the primary panel 2, and the concave groove 12a in the opposite direction is discontinuously formed with a space 2A interposed therebetween. Formed alternately.

3B is a bottom view viewed from below by separating only the secondary panel 4. The secondary lower panel 42 of the secondary panel 4 is not a rectangular closed panel as a whole, but a flap shape extending from the secondary side panel 40 periodically with a space 4A interposed therebetween, Secondary side panel 40 Therefore, the other side protrusion 46a is continuously formed along the entire length direction of the secondary panel 4, and one side protrusion 46 in the opposite direction is discontinuously formed with the space 4A interposed therebetween. Formed alternately.

When assembling the primary and secondary panels (2, 4), the concave grooves and protrusions (12, 46; 12a, 46a) made to be discontinuous and continuous are correspondingly fitted, so the left and right forces are symmetrically balanced. Have. In addition, since there is a free space such as the spaces 2A and 4A, sufficient elasticity and flexibility can be provided when the primary and secondary panels 2 and 4 are bent by utilizing the free space. The casing 1 in which both the primary and secondary panels 2 and 4 are assembled forms a shape like a serpentine joint. The protrusion 46 is movable along the concave groove 12, and since the protrusion 46a is movable along the concave groove 12a, a bending operation with rapid winding can be smoothly performed while adjusting their positions. Once bent, the bent shape is maintained as it is by the frictional force between the protrusion and the concave groove.

Embodiments of the present invention are based on the structure of the primary and secondary panels 2 and 4 described above.

In FIG. 1 again, a thick circular portion 10 is formed at the top of the primary side panel 22 of the primary panel 2 and a circular concave groove 10a opened outward in the circular portion 10 is formed. Are doing. Similarly, in the secondary side panel 40 of the secondary panel 4, a thick circular portion 44 is formed, and a circular concave groove 44a opened outwardly in the circular portion 44 is formed.
