DETAILED DESCRIPTION OF THE INVENTION

[0016] Referring to FIGS. 1-8, an origami lamp 10 as shown in FIGS. 5-8 is formed from a planar bendable sheet 20 as shown in FIGS. 1-4.

[0017] Referring to FIGS. 1-3, the planar bendable sheet 20 primarily includes a translucent sheet body 21, a light source 22, and a translucent cover 23.

[0018] The translucent sheet body 21 is a translucent plastic sheet made of, but not limited to, polypropylene (PP), which has a front surface 211 as shown in FIG. 1, and a back surface 212 as shown in FIG. 2. The translucent sheet body 21 is manufactured with a specific outline in a way that the circumference 213 of the translucent sheet body 21 consists of a lower curve 214 with multiple relatively larger radiuses of curvature, an upper curve 215 with multiple relatively smaller radiuses of curvature, and two junctions 216 of the lower curve 214 and the upper curve 215. In addition, the translucent sheet body 21 is manufactured with many grooves recessed from the front surface 211, that will be specified hereunder, and a light installation groove 217 recessed from the back surface 212 as shown in FIGS. 2 and 3. It is to be mentioned, the so-called “curves”, e.g. lower and upper curves 214 and 215, are actually realized by piecewise continuous straight lines in this embodiment. However, in another embodiment, they are realized by continuous smooth curves. In other words, a curved edge or curved fold may be realized as a smooth curve or as a series of straight segments approximating a curved line, as is shown in this embodiment.

[0019] The light source 22 is an LED (light emitting diode) light strip including a flexible printed circuit (FPC) 221 made of, but not limited to, glass fiber and copper foil, and a plurality of LED light beads 222, thereby shaped as a planar flexible elongated strip. The LED light strip 22 is embedded in the light installation groove 217. The cover 23, which is also made of plastics such as polypropylene (PP), is also embedded in the light installation groove 217 and covers the LED light strip 22. The cover 23 is fixed in the light installation groove 217 by ultrasonic welding, or may be fixed there by gluing. The planar bendable sheet 20 further includes a power cord 24 electrically connected with the LED light strip 22, and a clip 25 disposed on the power cord 24, that will be specified hereunder.

[0020] Referring to FIG. 1, the grooves on the front surface 211 primarily includes an annular fold line 31, two inner radial fold lines 32 extending from a main point 33 to the annular fold line 31, and two outer radial fold lines 34 extending from two junctions 35 of the annular fold line 31 and the two inner radial fold lines 32 to the two junctions 216 of the circumference 213. The two junctions 35 divide the annular fold line 31 into a lower segment 311 and an upper segment 312. The annular fold line 31 and the two outer radial fold lines 34 divide the planar bendable sheet 20 into top, middle and bottom sections 26, 27 and 28. Specifically speaking, the middle section 27 is defined by the annular fold line 31; the bottom section 28 is defined by the lower segment 311 of the annular fold line 31, the lower curve 214 of the circumference 213 and the two outer radial fold lines 34; the top section 26 is defined by the upper segment 312 of the annular fold line 31, the upper curve 215 of the circumference 213 and the two outer radial fold lines 34. The two inner radial fold lines 32 divide the middle section 27 into a lower part 271 and an upper part 272, wherein the light source 22 is provided in the upper part 272. Referring to FIGS. 2-3, the LED light strip 22 includes a section 223, namely a central section, located along the upper segment 312 of the annular fold line 31, and two other sections 224, namely lateral sections, extending from two ends of the section 223 toward the main point 33 along the two inner radial fold lines 32 respectively.

[0021] Referring to FIG. 1, the grooves on the front surface 211 further includes a plurality of inner radial grooves 36 provided in the lower part 271 and the upper part 272 of the middle section 27 and extending from the main point 33 to the annular fold line 31 radially, and a plurality of outer radial grooves 37 provided in the bottom section 28 and the top section 26 and extending from the annular fold line 31 to the circumference 213 radially.

[0022] The above-described planar bendable sheet 20 as shown in FIGS. 1-3 can be formed into the origami lamp 10 as shown in FIGS. 5-8 by an act of bending the planar bendable sheet 20 and fastening means. Referring to FIGS. 5-8, the origami lamp 10 includes a lamp stand 11 having a standing portion 111 and a connecting portion 112 integrally connected with the standing portion 111, a light emitter 12 integrally connected with the connecting portion 112 of the lamp stand 11, and a lampshade 13 integrally connected with the light emitter 12 and the standing portion 111 of the lamp stand 11. The standing portion 111 of the lamp stand 11 is shaped as a tapered tube from the bottom section 28 of the planar bendable sheet 20 by the aforesaid act and fastening means in a way that two lateral edges 281 of the bottom section 28 are connected or abutted with each other. In other words, the standing portion 111 of the lamp stand 11 has two lateral edges connected or abutted with each other. The connecting portion 112 is a concaved recess shaped as a cone extending from the top of the standing portion 111 thereinto, which is formed from the lower part 271 of the middle section 27 of the planar bendable sheet 20 by the aforesaid act and fastening means in a way that two radial edges 273 of the lower part 271 extending from the main point 33 are connected or abutted with each other. In other words, the connecting portion 112 is inwardly recessed from the top of the standing portion 111 in a way that the connecting portion 112 has a cone shape, a main point 33 and two edges extending from the main point 33 and being connected or abutted with each other. The light emitter 12 is shaped as another cone extending from the connecting portion 112 upwardly, which is formed from the upper part 272 of the middle section 27 of the planar bendable sheet 20 by the aforesaid act and fastening means in a way that two radial edges 274 of the upper part 272 extending from the main point 33 are connected or abutted with each other. In other words, the light emitter 12 upwardly and expandly extends from the main point 33 of the connecting portion 112 in a way that the light emitter 12 has a cone shape and two edges connected or abutted with each other. The lampshade 13 is shaped as a cloak extending from the top of the light emitter 12 outwardly and downwardly, which is formed from the top section 26 of the planar bendable sheet 20 by the aforesaid act and fastening means in a way that two lateral edges 261 of the top section 26 are connected or abutted with each other. In other words, the lampshade 13 has two lateral edges connected or abutted with each other.

[0023] The aforesaid fastening means may be realized in this embodiment by fastening the two lateral edges 281 of the bottom section 28 of the planar bendable sheet 20 with the clip 25. Specifically speaking, the clip 25 is provided at each end thereof with two feet 251, as shown in FIG. 2; the power cord 24 is clipped between the two feet 251 of an end of the clip 25; the two lateral edges 281 of the bottom section 28 is clipped between the two feet 251 of the other end of the clip 25. Through the fastening means, the origami lamp 10 formed from the planar bendable sheet 20 is kept in the stereoscopic status. Besides, the two feet 251 for clipping the power cord 24 is adapted for standing on a plane such as a desktop along with the lamp stand 11, as shown in FIG. 7. It is to be understood that any fastening member, such as snap on button, loop and hook fastener, needle, pin, etc., that can hold two lateral edges 281 of the bottom section 28 of the planar bendable sheet 20 can be used in the present invention. Further, as shown in FIG. 4, the power cord 24 may be detachably connected with the LED light strip 22 through a pair of USB connectors 29 and 30. Specifically speaking, the USB connector 29 is fixed at an end of the LED light strip 22, and the USB connector 30 is fixed at an end of the power cord 24, so that the power cord 24 can be connected with the LED light strip 22 or detached therefrom.

[0024] When the origami lamp 10 is turned on, light is emitted from the LED light strip 22 provided in the light emitter 12. The central section 223 of the LED light strip 22 is located along the opening 121 at the top of the light emitter 12, therefore the top of the light emitter 12 is relatively brighter and emits much light toward the lampshade 13. Besides, the lateral sections 224 of the LED light strip 22 extend from the central section 223 toward the apex 122 at the bottom of the light emitter 12, therefore the light from the lateral sections 224 is centralized at the bottom of the light emitter 12. Because the front surface 211 of the planar bendable sheet 20 is formed into the external surface 113 of the lamp stand 11, the external surface 123 of the light emitter 12 and the internal surface 131 of the lampshade 13, the power cord 24 connected with the LED light strip 22 extends from the internal surface 124 of the light emitter 12 and mostly hidden inside and under the lamp stand 11.

[0025] As a result, the planar bendable sheet 20 can be easily formed into the origami lamp 10 by the act of bending the planar bendable sheet 20 and the fastening means realized by using the clip 25 in this embodiment, so that the origami lamp 10 has the stereoscopic shape for suitably used on the desk. Therefore, the planar bendable sheet 20 can serve as the product for sale, and the consumer can form the planar bendable sheet 20 into the origami lamp 10 easily. In other words, it is convenient to store and transport the product of the present invention in the form of a planar sheet.
