5 is a bottom view and a cross-sectional view of a flexible lighting device according to an embodiment of the present invention.

Referring to FIG. 5 , on the lower surface of the flexible lighting device 102 , a cutting mark 117 indicating a portion where the flexible lighting device 102 is cut may be displayed. Here, the cutting mark 117 may be displayed on the lower surface of the flexible substrate 111 . A plurality of cutting marks 117 may be provided on the lower surface of the flexible substrate 111 to be spaced apart from each other in the longitudinal direction of the flexible substrate 111 . And, the cut mark 117 may be provided to be identifiable from the outside.

In an exemplary embodiment, the cut mark 117 may be displayed on the lower surface of the flexible substrate 111 . For example, a plurality of cutting marks 117 may be provided to be spaced apart from the lower surface of the flexible substrate 111 along the center of the flexible substrate 111 . The first protection unit 113 - 1 may be provided to surround the upper surface of the flexible substrate 111 , and the second protection unit 113 - 2 may be provided to surround the lower surface of the flexible substrate 111 .

In addition, the light blocking unit 115 may be provided on one side (left side in FIG. 5 ) and an upper surface of the first protection unit 113 - 1 and a lower surface of the second protection unit 113 - 2 . In this case, the light blocking unit 115 is not formed on the other side (the right side in FIG. 5 ) of the first protection unit 113 - 1 , and the light generated by the lighting means 121 is transmitted to the light blocking unit 115 . is irradiated to the other side of the first protection part 113-1 on which is not formed.

That is, in the flexible lighting device 102, the lighting means 121 is formed in the upper direction, but the light irradiation direction is the right direction. The first type of flexible lighting device may be used by bending upward and downward with respect to the surface on which the flexible substrate 111 is placed. In other words, the bending direction of the first type of flexible lighting device may be a direction perpendicular to the light irradiation direction.

Here, the light blocking part 115 may not be formed in the central region of the flexible substrate 111 where the cut mark 117 is displayed on the lower surface of the second protection part 113 - 2 . In this case, the second protection part 113 - 2 is made of a material that can transmit light, so that the cut mark 117 is identifiable to the user's eyes at the lower part of the flexible lighting device 102 .

In addition, the light blocking unit 115 may be formed on one side and an upper surface of the first protection unit 113 - 1 , and only the second protection unit 113 - 2 may be formed on the lower surface of the flexible substrate 111 . Even in this case, the cut mark 117 in the lower part of the flexible lighting device 102 is identifiable to the user's eyes.

In addition, in the flexible lighting device 102, an opening is formed in a portion where the cutting mark 117 is formed, so that the cutting mark 117 may be identifiable from the outside. For example, an opening may be formed along the center of the flexible lighting device 102 on the lower surface of the flexible lighting device 102 . However, the present invention is not limited thereto, and the cutting mark 117 is provided on the lower surface of the flexible substrate 111 and may be provided in various forms that can be identified from the outside.

In this way, the cutting mark 117 is provided on the lower surface of the flexible substrate 111 and identifiable from the outside. (102) It is possible to accurately find the part to be cut and cut.

That is, even if the flexible lighting device 102 is provided to be cutable in several parts, if the cut mark 117 is displayed on the outer surface of the flexible lighting device 102, when the flexible lighting device 102 is bent, the cut mark ( 117) may move and become inconsistent with the area to be cut. By the way, when the cutting mark 117 is provided on the lower surface of the flexible substrate 111 and identifiable from the outside, even if the flexible lighting device 102 is bent, the cutting mark 117 coincides with the part to be actually cut. As a result, the user can properly find and cut the part to be cut of the flexible lighting device 102 .

The upper surface of the part 113-1 is irradiated.

That is, in the flexible lighting device 102 , the lighting means 121 is formed in an upward direction, and the light irradiation direction is also an upward direction. As described above, a flexible lighting device in which the direction of the lighting means 121 and the light irradiation direction coincide may be referred to as a “second type of flexible lighting device”.

This second type of flexible lighting device may be used by being bent in an upper direction that is a light irradiation direction and a lower direction opposite to that of the light irradiation direction. In other words, the bending direction of the second type of flexible lighting device may be an upper direction that is a light irradiation direction and a lower direction opposite to that of the light irradiation direction.

In the disclosed embodiment, the flexible lighting device of the first type has a bending direction perpendicular to the light irradiation direction, and the second type of flexible lighting device has a bending direction that is the light irradiation direction and the opposite direction. The ease of installation of the flexible lighting device 102 may be increased. In addition, when the first type of flexible lighting device and the second type of flexible lighting device are connected to each other through a connection device, lighting direction can be varied as lighting directions are different from each other.
