[0047] Reference will now be made in detail to exemplary embodiments illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout.

[0048] Fig. 1 illustrates an exploded perspective view of a light-emitting diode (LED) lighting module 100 according to an exemplary embodiment. Fig. 2 illustrates a perspective view of the LED lighting module 100 the Fig. 1. Fig. 3 illustrates a front view of the LED lighting module 100 the Fig. 2. Fig. 4 illustrates an enlarged drawing of a section of the LED lighting module 100 the Fig. 3. Fig. Figure 5 illustrates a top view of a configuration of the LED lighting module of the Fig. 3 excluding a reflective section.

[0049] With reference to the Fig. 1 and Fig. 2, the LED lighting module 100 an LED arrangement 110 , a dispersal section 130 and a reflective section 150 The LED arrangement 110 , which are equipped with a plurality of LEDs 111 equipped, a side wall can 115 to accommodate the majority of LEDs 111 to include or encompass. The dispersion section 130 is detachable with the LED arrangement 110coupled and can be a dispersion plate 131 to disperse light emitted by the LEDs 111 emitted. The reflective section 150 is solvable with the dispersion section 130 coupled and can have a reflective section 150 to reflect light emitted by the LEDs 111 is emitted.

[0050] As a result, light emitted by the LEDs 111 emitted, through the scattering section 130 scattered and can be reflected by the reflective section 150 reflected to provide light.

[0051] Each element of the LED lighting module will be described here.

[0052] The LED arrangement 110 can be a mounting plate 112 , on or with which the LEDs 111are coupled at regular intervals so that the array of LEDs has a predetermined shape, and a side wall 115 which are connected to the mounting plate 112 along the periphery or circumference of an upper section of the mounting plate 112 coupled to the majority of LEDs 111 to enclose or surround.

[0053] The majority of LEDs 111 can emit light when the LEDs 111 with a printed circuit board (PCB = Printed Circuit Board) (not shown) on the mounting plate 112 connected and supplied with a current. Although a majority of LEDs 111 As described herein, as illustrated in the drawings, the LED arrangement 110 a single LED if the individual LED provides the desired amount of light. Each LED 111may comprise a semiconductor layer of a first type, an active layer, and a semiconductor layer of a second type, and may emit light by performing recombination between an electron and a hole when a voltage is applied.

[0054] The LED arrangement 110 , configured as described above, can be used as a single product. For example, the LED array 110 as a lighting machine, for example a local lighting machine, since the LED arrangement 110 can have a structure that provides satisfactory light quality.

[0055] The dispersion section 130 can be determined by the LED arrangement 110 be solvable, as opposed to one with the LED arrangement 110 Integrated, and therefore the LED lighting module can 110be used in various combinations.

[0056] The dispersion section 130 Light emitted by the LEDs 111 the LED arrangement 110 emitted, scatter and mix to create a film defect (artifact) which is present in the LED array 110 occurs in which the LEDs 111 are arranged.

[0057] As in Fig. 1, the dispersion section 130 the dispersion plate 131 , which also serves as a dispersion foil 131 in the present embodiment, a scattering body 132 , which can be detachably connected to the side section wall 115 the LED arrangement 110 is coupled, and a plate fastening attachment or foil fastening attachment 135 which can be detachably connected to the dispersing body 132 which the diffusion foil131 at an upper section of the dispersing body 132 attached.

[0058] The plate fastening attachment or film fastening attachment 135 and the diffusion body 132 can be coupled together. A selected diffusion foil 131 can be attached to an upper section of the dispersing body 132 placed and then the foil attachment can 135 on an upper section of the diffusion foil 131 be arranged in such a way that the diffusion foil 131 between the scattering body 132 and the film fastening attachment 135 In this example, the coupling between the scattering body 132 and the film fastening attachment 135 a clamping coupling and the like, but examples of the coupling structure are not limited to this.

[0059] Here is the dispersion foil131 an element which emits light which is emitted by the LEDs 111 emitted, directly scatters and mixes, and it can be a type of lens or it can be a polycarbonate (PC) or a polymethyl methacrylate (PMMA)-based transparent plastic, glass, a semi-transparent plastic, or the like. The color of light emitted by the LED 111 emitted, can be achieved by further enclosing or containing a fluorescent substance in a material of the diffusing film 131 Likewise, the brightness of the light output can be determined based on the type of diffusion film 131 which is used, should be appropriately adapted.

[0060] As an example, a micropattern may be formed on at least one surface of the diffusing film 131 The micropattern can enhance a light diffusion effect. In this example, the diffusion film can 131be formed of a transparent material to which a diffusing material is not added, or it may be formed of a transparent material to which a diffusing material is added.

[0061] As described above, the LED lighting module 100 in a structure in which the LED arrangement 110 and the dispersion section 130 are detachably coupled together.

[0062] Accordingly, a plurality of first projections 116 which protrude in an outward direction, on the side wall 115 the LED arrangement 110 be formed, and a plurality of first insertion elements 136 , in which the majority of first projections 116 is partially insertable, can be attached to a side wall of the dispersing body 132 of the dispersion section 130 be educated.

[0063] The LED arrangement 110 and the dispersion section 130 can be placed in one position and coupled together, and the dispersion section 130 can then be in one direction with respect to the LED arrangement 110 be rotated so that the dispersion section 130 with the LED arrangement 110 is coupled. Disassembly can also be easily performed in reverse.

[0064] As in Fig. 5, the plurality of first projections 116 along a circumference of the side wall 115 the LED arrangement 110 be formed at regular intervals. Although three first projections 116 in Fig. 5, the number of first protrusions is not limited thereto. Likewise, the plurality of first protrusions may not be arranged at regular intervals.

[0065] Three first insertion elements 136 can be arranged at regular intervals along a circumference of the scattering body 132 be arranged so that they correspond to the plurality of first projections 16 As in Fig. 4, the first insertion element 136 from a lower section of the side wall of the dispersing body 132 in an upward direction or upper direction and may then be cut in a lateral direction to form the first projection 116 to lead.

[0066] That is, the dispersion section 130 can be placed in a position on or on the LED array 110 and can be used with the LED arrangement 110 be coupled so that the first projection 116 the LED arrangement 110 into a section 136a of the first insertion element 136which can be introduced in an upward direction or upper direction of the dispersion section 130 Subsequently, if the dispersion section 130 regarding the LED arrangement 110 is turned, the first projection 116 together with a section 136b , which in a lateral direction of the first insertion element 136 cut, can be inserted into an inside and can be held there.

[0067] In this example, to make it the first projection 116 to enable the first insertion element to be inserted smoothly 136 to be introduced, a curved section 136c between the section 136a , which in the upward direction of the first insertion element 136 is cut, and the section 136b , which is cut in the lateral direction, as in Fig. 4. Consequently, the first projection 116 slightly into the mainly inner section of the first insertion element 136 over or through the path of the first insertion element 136 be introduced.

[0068] As in Fig. 4, a stopper 137 , which is formed in a protruding shape, in the mainly inner portion of the first insertion member 136 be included. The stopper 137 can prevent the first lead 116 arbitrarily the first insertion element 136 leaves when the first lead 116 in the first insertion element 136 based on a coupling between the LED array 110 and the dispersion section 130 is held.

[0069] As a result, the LED arrangement 110 and the dispersion section 130can be easily coupled and separated from each other, and therefore the LED array 110 used independently or it can be coupled with the dispersion section 130 be used.

[0070] The reflective section 150 can be used with the dispersion section 130 , as in the Fig. 1 to Fig. 3 is illustrated, can be detachably coupled and can therefore light emitted by the LED 111 is emitted and through the scattering section 130 has been scattered and mixed.

[0071] The reflective section 150 can reflect a body 151 in the form of a hollow cylinder, which at least an upper portion of the scattering body 132 encloses or surrounds, and can create an enlarged body 155to reflect light whose diameter is determined from an upper portion of the reflecting body 151 to one end of the enlarged body 155 is increasingly enlarged.

[0072] The reflective section 150 may also have a structure which is detachably connected to the dispersing section 130 In this example, a coupling structure can be formed between the reflective section 150 and the dispersion section 130 be simple and therefore pairing and dissolution can be easily carried out.

[0073] According to the coupling structure, a plurality of second projections 138 which protrude in an outward direction, on an outer side wall of the dispersing body 132 of the dispersion section 130 be formed, and a plurality of second insertion elements 156, into which the plurality of second projections 138 can be inserted, can be attached to a side wall of the reflecting body 151 of the reflective section 150 The configurations of the second protruding sections 138 and the second insertion elements 156 may be essentially the same as that of the first projections 116 and the first insertion elements 136 and accordingly detailed descriptions thereof will be provided only roughly.

[0074] Similar to the coupling structure between the dispersion section 130 and the LED arrangement 110 the reflective section 150 in a position at or on the dispersion section 130 and can then be used with the dispersal section 130 When pairing, the second projection 138 , which is attached to the dispersing body 132is formed, into a portion of the second insertion element 156 which is directed in an upper or upward direction of the reflecting body 151 Subsequently, if the reflective section 150 regarding the dispersion section 130 is rotated, the second projections 138 be inserted into an inner side along a portion extending in a lateral direction of the second insertion element 156 cut and they can be kept there.

[0075] In this example, a curved portion in the internal structure of the second insertion element 156 in the same way as the internal structure of the first insertion elements 136 rounded and a stopper (not illustrated) which is essentially the same as the stopper 137, may be included at an inner end portion to prevent the second projections 138 the second insertion elements 136 leave arbitrarily.

[0076] Fig. Fig. 6 illustrates examples of a light distribution angle obtained using the diffusion section of the Fig. 2. With reference to Fig. 6, the light distribution angle can be adjusted using the diffusion film 131 , which in the dispersion section 130 included, be customizable.

[0077] The example in the upper left corner of Fig. 6 shows a light distribution angle of 120 degrees when light is only emitted by the LED array 110 emitted without coming into contact with the scattering section 130 The remaining examples of the Fig. 6 show light distribution angles when the diffusion section 130 and the LED arrangement 110are coupled together. The light distribution angle can be appropriately adjusted to 100 degrees, 90 degrees, 80 degrees or the like by properly selecting among a plurality of diffusing films, wherein the diffusing film 131 with the dispersion section 130 to be coupled.

[0078] According to this exemplary embodiment, the LED arrangement 110 and the dispersion section 130 can be easily coupled and separated from each other, and the diffusion foil 131 , which in the dispersion section 130 included can be properly selected and accordingly the brightness of light, the light distribution angle and the like can be appropriately adjusted.

[0079] Hereinafter, an LED lighting module according to another exemplary embodiment will be described, and portions which are substantially the same as the portion of the LED lighting module 100 of the exemplary embodiment described above will be omitted for the sake of conciseness.

[0080] Fig. 7 illustrates an exploded perspective view of an LED lighting module 200 according to another exemplary embodiment and Fig. 8 illustrates a front view of the LED lighting module 200 the Fig. 7.

[0081] With reference to the Fig. 7 and Fig. 8 has the LED lighting module 200 an LED arrangement 210 and a reflective section 250 which are essentially the same as the LED arrangement 110 and the reflective section 150The LED arrangement 210 can, however, be directly connected to the reflective section 250 as a package structure, unlike the scheme in which an LED array is coupled to a dispersing portion and then a reflective portion is coupled to the dispersing portion.

[0082] As a result, light emitted by the LED array 210 emitted by a through the reflecting section 250 To be led through, to be guided.

[0083] A coupling structure of the LED array 210 and the reflective section 250 is based on the structure between the LED array 110 and the dispersion section 130 and the coupling structure between the dispersion section 130 and the reflective section 150 be described. A plurality of projections 216can be seen on the LED arrangement 210 be formed, and a plurality of insertion elements 256 , which of the majority of projections 216 can be seen on the reflective section 250 be educated.

[0084] Consequently, as in the Fig. 7 and Fig. 8, the reflective section 250 in a position on or on the LED array 210 and can then be connected to the LED arrangement 210 The advantage 216 , which is connected to the LED arrangement 210 can be inserted into a section of the insertion element 256 which is directed in an upward direction or upper direction of the reflecting section 250 Subsequently, if the reflective section 250 regarding the LED arrangement 210 is rotated, the projection 216be inserted into an inner side along a portion which is in a lateral direction of the insertion element 256 and can be held there. In this example, a curved section of the insertion element 256 rounded to allow easy insertion of the projection 216 into the insertion element 256 to enable, and a stopper 257 can be attached to an inner end portion of the insertion element 256 be included to prevent the projection 216 arbitrarily the insertion element 256 leaves.

[0085] As described above, the reflective section 250 which reflects light directly without a diffusion section, detachable with the LED array 210 Consequently, light emitted by an LED 211 the LED arrangement 210 emitted, are directly reflected.

[0086] A diffusion film (not shown) which is attached to the diffusion film 131 , which is described above, can be connected to the reflective section 250 be coupled for a scattering of light.

[0087] Hereinafter, an LED lighting module according to still another exemplary embodiment will be described, and portions substantially the same as those described above with respect to the above-described embodiments will be omitted for the sake of conciseness.

[0088] Fig. 9 illustrates an exploded perspective view of an LED lighting module 300 according to another exemplary embodiment and Fig. 10 illustrates a front view of the LED lighting module 300 the Fig. 9.

[0089] With reference to the Fig. 9 and Fig. 10, the LED lighting module can comprise an LED array 310 and a reflective section 350 The LED arrangement 310 can be a plurality of LEDs 311 and a dispersal section 330 to disperse light emitted by LEDs. The reflective section 350 , which is detachably connected to the LED arrangement 310 coupled, light emitted by the LEDs 311 Although the reflective section 350 , which is illustrated, has an upper portion formed in the shape of a funnel, the shape of the reflecting portion 350 not limited to that.

[0090] The dispersion section 330 , ie a lens-type diverging film 330 can be used with the LED arrangement 310 be integrated. Consequently, a coupling structure between the LED array310 and the dispersion section 330 be simple and light, which is emitted by the LEDs 311 emitted can be scattered and mixed and can be reflected by the reflecting section 350 are emitted.

[0091] With reference to the Fig. 9 and Fig. 10 the LED arrangement 310 a mounting plate 312 , on which the majority of LEDs 311 is installed at regular intervals, and a foil fastening element 315 which can be detachably connected to the mounting plate 312 is coupled, and the dispersion section 130 can be opened with a film fastening element 315 which opens in one direction.

[0092] The dispersion section 330 A lens-type diffusion film can 330 and can be attached to an inside of the opening of the film fastening element 315A position of the diffusion foil 330 can be achieved by placing the diffusion foil 330 between the mounting plate 312 and the film fastening element 315 and coupling them together.

[0093] The LED arrangement 310 may have a structure which allows easy coupling and separation and therefore a user can appropriately select the dispersion section from a plurality of dispersion sections 330 which provides a desired light distribution angle. Here, a micropattern on the diffusion film can 330 be formed, and the diffusion foil 330 may be formed from a resin material filled with a diffusing material and a fluorescent substance. The material of the diffusing film 330However, the pattern formed on an outer surface and the like are not limited thereto.

[0094] The LED device 310 and the reflective section 350 can be coupled in substantially the same way as the coupling structures of the previously described embodiments. That is, a plurality of projections 316 can be attached to an external side surface of the film fastening component 315 the LED arrangement 310 be formed, and a plurality of insertion elements 356 can be seen on the reflective section 350 , corresponding to the plurality of projections 316 be educated.

[0095] Consequently, the LED arrangement 310 and the reflective section 350 be coupled together. Subsequently, if the reflective section 350 regarding the LED arrangement 310is rotated, the projection 316 the LED arrangement 310 into an inner side of the insertion element 356 of the reflective section 350 introduced and kept there.

[0096] Hereinafter, an LED lighting module according to yet another exemplary embodiment will be described, and portions which are substantially the same as those described with respect to the LED lighting modules 100 , 200 and 300 described will be omitted for the sake of conciseness.
