In addition, in the case where reference numerals are not given in the term "illumination device", the illumination device encompassing the illumination devices (1, 2, 3, 4, 5, 6) according to the first to sixth embodiments is shown.

Hereinafter, a first single illumination module, a second single illumination module, a third single illumination module, and a lighting device according to embodiments will be described with reference to Figs.

Single lighting module

Unlike a conventional lighting device, the lighting device 1 according to the embodiment to be described later is formed in a unique manner. That is, one illumination device 1 including one single illumination module 10 and one power control section 20, or a plurality of single illumination modules 10 and at least one power control section 20 Thereby forming one lighting device 1 including the lighting device. The illumination device 1 of various sizes is formed by combining one or a plurality of the single illumination modules 10 so that there is no limitation in forming the illumination device 1 of the desired size.

The single illumination module 10 will describe three kinds of the first single illumination module 10A, the second single illumination module 10B and the third single illumination module 10C, There may be a module.

Figure 1 is a cross-sectional view of a first single illumination module 10A, Figure 2 is a cross-sectional view of a second single illumination module 10B, and Figure 3 is a cross-sectional view of a third single illumination module 10C. 1 to 3 and 8, a single lighting module 10 includes a case 100, a light emitting unit 200 mounted on a bottom plate 110 of the case 100, a light emitting unit 200 mounted on a top surface of the light emitting unit 200, And a diffusion plate 300 disposed at an upper portion of the light emitting unit 200 while being spaced apart from the light emitting unit 200. [

The first single illumination module 10A is used when forming the illumination device of the first embodiment in which the first single illumination module 10A is coupled in two directions perpendicular to the direction of Figure 7 (a). Alternatively, a single lighting module 10 including one light emitting portion 200 is used on both sides when forming the lighting device of the third embodiment in which three pieces are combined in a direction perpendicular to the direction of Fig. 13 (a). Alternatively, a single lighting module 10 including one light emitting portion 200 is used on both sides when forming an illumination device of an embodiment (not shown) coupled in four or more directions perpendicular to the direction (a) .

Referring to FIGS. 1, 5, 6 and 8, the case 100 of the first single illumination module 10A has a bottom plate 110, and includes side walls extending vertically from both ends of the bottom plate 110, And a louver 130 extending from an end of the sidewall 120 and inclined at an obtuse angle with respect to the surface of the diffuser plate 300. It is also possible to have the top plate 140 instead of the louver 130, as in the second embodiment 1B shown in Figs. 11 and 12.

A first bracket coupling part 151 for coupling the single illumination modules 10 is formed at one end of the one louver 130 of the case 100 of the first single illumination module 10A, A ceiling fixing frame 160 is formed. However, the first bracket coupling part 151 must be formed at the end of the one louver 130 of the case 100 of the first single illumination module 10A, but the ceiling fixing frame 160 may not be formed. As a result, the first single illumination module 10A has the first bracket coupling 151 at the end of the first louver 130, which differs from the second single illumination module to be discussed below.

The second single illumination module 10B is used to form the illumination device of the fourth embodiment having only one single illumination module including one light emitting portion 200. [ Alternatively, the single illumination module including one light emitting portion 200 may be used as a single single illumination module in the case of forming the illumination device of the third embodiment in which three light emitting modules are combined in a direction perpendicular to the direction (a) Side lighting module. Alternatively, when a single lighting module including one light emitting unit 200 is combined into four or more modules in a direction perpendicular to the (a) direction, Or as a single illumination module on both sides.

2, 13 and 14, the case 100 of the second single illumination module 10B includes a side wall 120 having a bottom plate 110 and extending vertically from both ends of the bottom plate 110, And a louver 130 extending from an end of the side wall 120 and tilted at an obtuse angle with respect to the surface of the diffuser plate. The upper plate 140 may be provided instead of the louver 130. A first bracket coupling part 151 for coupling the single illumination modules 10 is formed at the ends of the both side louvers 130 of the case 100 of the second single illumination module 10A.

The third single illumination module 10C is used to form the illumination device according to the fifth embodiment shown in Fig. 16 having only one single illumination module including two light-emitting portions 200. Fig. Alternatively, a single illumination module including two light emitting portions 200 is used to form the illumination device of the sixth embodiment in which two light emitting modules are coupled in a direction perpendicular to the direction of FIG. 19 (a). Alternatively, a single illumination module including two light emitting units 200 may be used to form an illumination apparatus of an embodiment (not shown) in which three or more light illumination modules are combined in a direction perpendicular to the direction (a).

The case 100 of the third single illumination module 10C will be described later in the description of the fifth embodiment.

1st Example

Fig. 4 is a perspective view of the lighting apparatus 1A according to the first embodiment, Fig. 5 is a perspective view showing a section of the lighting apparatus 1A according to the first embodiment, 7 is an exploded perspective view of the lighting apparatus 1A according to the first embodiment and Fig. 8 is a sectional view of two cases 100 of the lighting apparatus 1A according to the first embodiment 9 is a perspective view showing a state where the light emitting unit 200 and the reflection plate 400 are coupled to each other and FIG. 10 is an exploded perspective view of the light emission unit 200 and the reflection plate 400. FIG.

 4 to 8, the lighting apparatus 1 includes two first single illumination modules 10A, and a power supply control unit 10A located in the space 170 between the two first single illumination modules 10A, Includes a bracket 30 that includes a first light source module 20 and a second single light module 10A, and may further include a side cover 40. [ Referring to FIG. 1, the first single illumination module 10A used in the first embodiment includes a case 100, a light emitting portion 200 accommodated in the case 100, and a diffusion Includes a plate 300, and may additionally include a reflector 400.

4 to 8, the first embodiment includes two first single illumination modules 10A, but the second single illumination modules 10B may be used to configure the first embodiment You may. Since the second single illumination module 10B has the first bracket engaging portion 151 at the end of the both side louvers 130, it is possible to combine the two second single illumination modules 10B to form the overall appearance of the first embodiment. There is no significant difference in appearance and function from the combination of the two first single illumination modules 10A.

Referring to FIGS. 5 and 6, the light emitting unit 200 may be disposed on the bottom plate 110 of the case 100. The power control unit 20 is disposed in the space 170 defined by the louver 130 and the side wall 120 connected thereto with the first bracket coupling portion 151 formed in the two first single illumination modules 10A . In this case, since the power supply control unit 20 is stacked below the bottom plate 110 and is not arranged in the vertical direction but horizontally arranged on the bottom plate 110, the thickness of the lighting apparatus 1 It becomes thin.

The ceiling of the building where ceiling embedded lighting is installed is generally a ceiling of a concrete structure, and a structure called M-BAR or T-BAR is installed in the direction of the floor from the ceiling, and M-BAR or T- . Since the power supply control unit 20 is stacked under the bottom plate 110 and disposed in the vertical direction, the direct-type lighting apparatus installed in the ceiling of a building usually has a thickness exceeding 70 mm or more. However, since electrical wiring and pipes for air conditioning are usually disposed between the ceiling of the concrete structure and the M-BAR or the T-BAR, the space for installing the lighting device is often very narrow. Therefore, when a conventional direct lighting type lighting device is embedded in a ceiling due to space constraints, there is a problem that the M-BAR is partially cut out and installed inconveniently or the lighting position is inevitably installed at an unintended position.

On the other hand, the lighting apparatus 1A according to the first embodiment preferably has a thickness of about 45 mm, so that even when the installation space is narrow, the lighting apparatus can be freely arranged on the ceiling surface and the installation is simple. Of course, the dimension of 45 mm is a numerical value for the purpose of comparison with the conventional lighting apparatus. Therefore, according to the thickness of the power supply control unit 20 and / or the dimensions of the case 100, ) Can vary in various ways.

The illumination device 1 may have a rectangular shape elongated in the first direction a, but the shape of the illumination device 1 may be variously changed depending on the installation position and installation environment of the illumination device 1 have.

The louvers 130 on both sides of the light emitting portion 200 are arranged on the opposite sides of the diffuser plate 300 so as to allow the light emitted from the light emitting portion 200 to be emitted with a desired light distribution angle and to lighten the glare from the light. ) At an obtuse angle. If the diffuser plate is not included and the angle with respect to the diffuser plate can not be specified, the louver 130 will be specified as having a slope extending from the end of the sidewall 120 and wider toward the outside than the sidewall 120 .

The inclination of the louver 130 can be variously modified depending on the design of the lighting apparatus 1. [ 9 and 10, the light emitting unit 200 may include an LED 210, a substrate 220 on which the LED 210 is mounted, and a heat-radiating sheet 240 disposed under the substrate 220 . The substrate 220 may have a coupling hole 230 for coupling with the case 100.

The reflector 400 reflects the light emitted from the LED 210 to the outside of the illuminator 1 and illuminates the side wall 120 of the case 100, It covers the inside of. It is preferable that the reflection plate 400 not only covers the inner surface of the side wall 120 but also the surface of the substrate 220 of the light emitting unit 200 except for the area where the LED 210 is disposed.

The power control unit 20 may include a power supply unit (PSU) (not shown) for supplying power to the lighting apparatus 1 and a driving unit (not shown) for controlling and driving the light emitting unit 200.

5, the diffusion plate 300 is disposed apart from the light emitting unit 200 in a direction in which light is emitted from the LED 210, and light emitted from the LED 210 corresponding to each point light source The light emitted from the light emitting unit 200 can have a uniform luminance with respect to the surface of the diffusion plate 300. [

The light emitting portion 200 is not formed on the front surface of the illuminating device 1 but is disposed on the bottom plate 110 of the case 100. [ Therefore, even when the same number of LEDs 210 are used, the distance between the LEDs 210 can be made narrower than the case of arranging the LEDs 210 on the front surface of the lighting apparatus, Can be reduced.

On the other hand, in order for the light emitted from the LED 210, which is a point light source, to pass through the diffusion plate 300 and become a surface light source, an area in which light emitted from the adjacent LED 210 is superimposed on the surface of the diffusion plate 300 , Which means that the LED 210 and the diffusion plate 300 must be sufficiently separated from each other. However, since the spacing distance is increased, it means that the thickness of the lighting apparatus 1 is increased, and the distance between the LEDs 210 must be reduced in order to reduce the spacing distance. The light emitting unit 200 is not formed on the front surface of the lighting apparatus 1 but is disposed on the bottom plate 110 of the case 100 so that the substrate 220 of the light emitting unit 200 is also mounted on the case 100 The width of the bottom plate 110 of the base plate 110 is limited. As a result, the spacing of the LEDs 210 disposed on the substrate 220 is naturally reduced, and the interval between the LEDs 210 and the diffusion plate 300 required to form the planar light source is also reduced.

Therefore, it is possible to provide the slim lighting apparatus 1 because of the above structural advantage. In addition, when light is irradiated on the irradiation surface of each LED in a state where there is no diffusion plate 300, a hot spot is generated. When the shape of the light source itself is directly irradiated onto the irradiation surface, a region where the light is sharply distinguished from a region where light is not sharply distinguished. In this case, a region irradiated with light such that a dark boundary and a boundary are clearly formed is called a hot spot . In the case of outdoor lighting such as a general indoor lighting or a streetlight, it is not preferable that a centralized lighting is not required, and the uniformity of the illuminated surface is lowered if a hot spot is generated. Use of the surface illuminating device as in the embodiment has an advantage that the occurrence of hot spots is reduced as compared with a conventional point illuminating device, so that the illuminance distribution on the illuminated surface becomes uniform and fatigue of eyes is reduced.

Second Example

Hereinafter, the lighting device 1B according to the second embodiment will be described in detail with respect to components. In describing the second embodiment, the same parts as those of the first embodiment will be referred to in the first embodiment, and redundant description will be omitted.

Fig. 11 is a sectional view of the lighting apparatus 1B according to the second embodiment, and Fig. 12 is another example of the lighting apparatus 1 according to the second embodiment.

The second embodiment is most different from the first embodiment in that the case 100 has the upper plate 140 in place of the louver 130.

Referring to FIGS. 11 and 12, the second embodiment includes two first single illumination modules 10A. Alternatively, two second single illumination modules 10B may be used to configure the first embodiment. You may. Since the second single illumination module 10B has the first bracket engaging portion 151 at the ends of both side upper plates 140, it is possible to combine the two second single illumination modules 10B to form the overall appearance of the first embodiment. There is no significant difference in appearance and function from the combination of the two first single illumination modules 10A.

12, when the height of the sidewall 120 is made higher than that in FIG. 11, the distance between the diffusion plate 300 and the light emitting unit 200 is kept equal to that of FIG. 11, Is formed in the interruption of the side wall (120). In this case, due to the sidewalls 120 which are perpendicular to the base plate 110 and / or the diffuser plate 300 and extend higher than in the first embodiment, the glare can be made more efficient than the first embodiment . However, the width of the area irradiated with light on the bottom surface may be smaller than that of the first embodiment, or the uniformity of the illuminance distribution on the irradiation surface may be lower than that of the first embodiment. Therefore, it is preferable that the second embodiment is installed and used in a situation in which the prevention of glare is more preferentially required than the width of the area irradiated with light and the illuminance distribution on the irradiated surface.

Third Example

Hereinafter, the lighting device 1C according to the third embodiment will be described in detail with reference to its components.

6th Example

Hereinafter, the lighting device 1F according to the sixth embodiment will be described in detail with respect to components. In describing the sixth embodiment, the same parts as those of the fifth embodiment are referred to in the fifth embodiment, and redundant description will be omitted.

20 is a perspective view of the lighting apparatus 1F according to the sixth embodiment, and Fig. 21 is a sectional view of the lighting apparatus 1F according to the sixth embodiment. Fig. 19 is an exploded perspective view of the lighting apparatus 1F according to the sixth embodiment, Fig.

The illumination apparatus 1F according to the sixth embodiment uses the third single illumination module 10C including two light emitting units 120 like the illumination apparatus 1E according to the fifth embodiment.

[ 19 to 21, the power supply control unit 20 may be a lighting device including only one of the two power supply control units 20. In this case, one power supply control unit 20 may include four light emitting units 200 The power control unit 20 may be located in the space 170 partitioned by the two inner louvers 130 and the side walls 120 of the third single illumination module 10C, The third single illumination may be located in the space where the third single illumination is coupled by the bracket 30.

Therefore, in this case, there is no problem in implementing the sixth embodiment, but a lighting apparatus of a larger size than the sixth embodiment can not be realized.

Hereinafter, components of the lighting apparatus 1 will be mainly described.

≪ Case (100) >

The description of the structure of the case 100 is omitted because it has been already discussed while explaining the first to sixth embodiments.

See FIGS. 6 and 8. FIG. The power control unit 20 is disposed in the space 170 defined by the louver 130 and the side wall 120 and the side wall 120 and the bottom plate 110 of the case 100 are coupled to each other. The case 100 and the power supply control unit 20 can be firmly coupled by sliding the second projection 22 formed at the lower end of the power supply control unit 20 into the power supply control unit coupling groove 152 formed at the boundary .

Although the power supply control unit coupling groove 152 is shown extending along the length of the case 100 along the first direction a shown in FIG. 7, it is not necessarily required to take such a shape, Quot; C "or" O "shape. A hole may be formed in the side wall of the case 100 without forming the power control unit engagement groove 152 and a hole may be formed in a portion of the power control unit 20 opposite to the hole of the side wall 120, The case 100 and the power supply control unit 20 may be combined. However, it is advantageous to form the power supply control unit coupling groove 152 in the case 100 through the extrusion molding method, and the case 100 and the power supply control unit 20 can be combined without additional screws or pins. It can be said to be a joining method.

There are two types of bracket coupling parts: the first bracket coupling part 151 and the second bracket coupling part 153. The first and second bracket engaging portions 151 and 153 may be formed in the case 100. The first bracket engaging portion 151 and the second bracket engaging portion 153 may be connected to the bracket 30, The modules can be firmly coupled to each other. Further, a side cover coupling groove 154 may be formed in the case 100. The side cover engagement groove 154 exists for engagement with the side cover 40, and a coupling method will be described in a separate table.

The material of the case 100 may be a metal material or a resin material having good heat radiation characteristics. An aluminum (Al) or silver (Ag) oxide film is formed on the surface of the case 100 to secure the wear resistance, corrosion resistance, durability, and the like of the case 100 and ensure a good appearance of the lighting apparatus 1 . In addition, although the louver 130 is primarily intended to prevent the glue from being used for its original use, the surface of the louver 130 may be surface-treated so that the surface of the louver 130 is well-reflected, The light efficiency can be increased.

The case 100 may be manufactured by separately manufacturing the bottom plate 110, the side wall 120 and the louver 130. However, the entire case 100 may be integrally formed by, for example, . When the case 100 is integrally formed, the diffusion plate coupling groove 180, the first and second bracket coupling parts 151 and 153, the power source control part 110, The groove 152, and the side cover engagement groove 154 are integrally formed at one time. The case 100 is integrally formed integrally in the longitudinal direction. In addition, when the case 100 is integrally formed by a method such as extrusion, the cross section of the case 100 is formed into a flat shape perpendicular to the longitudinal direction. For example, the cross section of the middle portion of the case 100 and the cross section of the portion near the end are the same. When the case 100 is integrally formed, the labor required to assemble various members can be reduced, and the manufacturing process can be simplified.

The first and second bracket coupling portions 151 and 153, the power source control portion coupling groove 152, the side cover coupling groove 154, and the like, described above, It is not always necessary to form them all at once, and at least one member may be formed integrally when the case 100 is molded. For example, the case 100 having only the base 110, the side wall 120, the louver 130 and the diffusion plate coupling groove 180 may be formed, and the base 110, the side wall 120, The case 100 having only the bracket coupling portions 151 and 153 may be formed.

Referring to FIG. 8, the diffusion plate coupling groove 180 may be formed at the boundary between the inner surface of the side wall 120 and the upper surface of the louver 130. 11 and 12, when the upper plate 140 is provided instead of the louver 130, the diffusion plate coupling groove 180 is formed in the middle portion of the inner side of the side wall 120, (Not shown).

Referring to FIG. 8, the first and second bracket engaging portions 151 and 153, the power control portion engaging groove 152, and the side cover engaging grooves 152 and 153 are formed on the outer surface of the side wall 120 of the case 100, 154 may be formed. 11 and 12, when the upper plate 140 is provided instead of the louver 130, the first and second brackets 130 and 132 are formed on the outer surface of the side wall 120 of the case 100 or on the lower surface of the upper plate 140, At least one of the power control unit coupling grooves 152 and the side cover coupling grooves 154 may be formed.

Since the case 100 is integrally formed, the heat can be effectively transmitted and discharged to the entire case 100, so that the lighting apparatus can have a good heat radiation characteristic. Of course, according to an embodiment, the louver 130 may be replaced by a top plate 140. More specifically, when various members constituting the case 100 are separately manufactured and joined together, the members are not in perfect surface contact with each other but partially point-contacted. The heat transmitted from the light emitting unit 200 to the bottom plate 110 is not sufficiently transmitted to the side wall 120 and the heat of the side wall 120 is not sufficiently transmitted to the louver 130, It can not be sufficiently used as a heat radiator. The heat generated from the light emitting unit 200 or the power supply control unit 20 is transmitted from the bottom plate 110 to the side wall 120 through the extrusion molding, So that it is uniformly conducted to the louver 130, and the heat radiation effect is excellent.

The heat dissipation effect will be further described. As described in the fifth embodiment, an additional member forming the case 100 may be formed at the lower end of the outermost louver 130. The purpose of forming the additional member may be to increase the surface area of the case 100, It is possible to take any shape that can enlarge the surface area of the case 100 and enhance the heat radiating effect. Accordingly, the additional member may form a closed curved surface together with the louver 130 and the side wall 120, may form a closed curved surface, may be formed with a heat dissipating hole, and may have irregularities formed in the louver 130 or the side wall 120 It may also play the role of a radiating fin.

Fig. 39 is a cross-sectional view of a lighting module having a louver 130 of another shape, and Fig. 40 is a cross-sectional view of a lighting module having a louver 130 of another shape. 39 and 40, the louver 130 may have a straight section, a parabola, an arc, or the like. However, what louver limit angle (?) Is more important than the shape of the louver 130 itself is more important.

Since the illumination device in which the louver 130 is formed has a specific louver limit angle? So that the diffusion plate 300 does not directly enter the field of view at the louver limit angle? It is important to have an appropriate louver limit angle ([theta]).

Fig. 41 is a view for explaining the louver limiting angle [theta] and the shielding angle [alpha] of the illumination device according to the embodiment. 41, unlike the louver 130 of FIG. 41 to reduce glare, if the louver 130 is formed to be substantially in line with the side wall 120, the louver limiting angle? α), which means that there is no glue at an angle larger than the louver limit angle (θ). Therefore, eye fatigue due to glue can be reduced even if it is a little away from the lighting device. However, the diffusion range of the light is excessively reduced and the irradiation surface becomes narrow.

On the other hand, unlike the louver 130 of FIG. 41, if the louver 130 is formed substantially parallel to the side wall 120, the louver limiting angle? Becomes large and the shielding angle? Becomes small, Although it means that there is no glare at angles greater than the limiting angle (θ), it means that the louver limit angle (θ) is too large to cause glare, . However, since the diffusion range of the light can be sufficiently wide, there is an advantage that the irradiation surface is widened.

Therefore, an illuminating device with a greater emphasis on increasing the area of the light-irradiated area should have a larger louver limit angle (&thetas;), and an illuminating device with a greater emphasis on preventing glare, .

It is preferable that the louver limit angle? Has a value between 0 and 90 degrees. When the louver limit angle? Has a value within this range, The direct light from the diffusion plate can not be seen.

Since the light emitting unit 200 is disposed on the bottom plate 110 of the case 100, the bottom plate 110 has a width and a length in which the light emitting unit 200 can be disposed, and the side wall 120 and the louver 130 And the diffusion plate 300 and / or the fixing protrusions 430 of the reflection plate 400 may be fitted in the diffusion plate coupling groove 180. In this case, The diffusion plate coupling groove 180 may be elongated along the first direction (a) shown in Figs. 7, 13, and 19.

When the diffusion plate 300 and / or the fixing protrusion 430 of the reflection plate 400 are slidably inserted into the diffusion plate coupling groove 180 and the side cover 40 is coupled to at least one end of the case 100, The diffusion plate 300 and / or the reflection plate 400 are sufficiently fixed. Therefore, there is no possibility that the diffuser plate 300 and / or the reflection plate 400 are detached from the illuminating apparatus while the illuminating apparatus is installed and operated or during transportation.

1 to 3, the side wall 120 of the case 100 is shown to extend in a direction perpendicular to the bottom plate 110. However, the side wall 120 may be substantially perpendicular to the bottom plate 110, And may be formed so as to have an inclination gradually increasing toward the outside. Although not shown, unevenness is formed on the lower surface of the case 100, and the surface area of the case 100 is widened, so that the heat radiation characteristic of the lighting apparatus can be improved.

≪ Multiple light emitting units 200 >

9 is a perspective view illustrating a state in which the light emitting unit 200 and the reflection plate 400 are coupled to each other, and FIG. 10 is an exploded perspective view of the light emission unit 200 and the reflection plate 400. FIG.

9 and 10, the light emitting unit 200 includes a substrate 220 on which a plurality of LEDs 210, a plurality of LEDs 210 are mounted, And the heat-radiating sheet 240 may be a heat-dissipating sheet.

The plurality of LEDs 210 may include at least one light emitting diode (LED) that emits red, green, blue, white, or yellow light. For example, the plurality of LEDs 210 may include red, green, and blue light emitting diodes (LEDs). The plurality of LEDs 210 may be formed of a combination of light emitting diodes (LEDs) that emit various color lights.

A plurality of LEDs 210 may be mounted on the substrate 220. The substrate 220 may be a printed circuit board (PCB). The printed circuit board may be an aluminum substrate, a ceramic substrate, a metal core PCB, a general PCB, or the like, printed with an insulator. The surface of the substrate 220 may be coated or painted white or silver to enhance the reflection efficiency.

 The substrate 220 includes circuitry capable of driving a plurality of LEDs 210. [ As shown in FIGS. 9 and 10, the plurality of LEDs 210 may be arranged along the rows and columns on the substrate 220, or may be arranged in various other ways. Further, the number of the plurality of LEDs 210 is more or less than that shown in the drawing. However, if the LEDs 210 are arranged too little, it is difficult for the illuminating device to function as a side illumination, so it is desirable to arrange an appropriate number of the LEDs 210 considering the function of the side illumination.

A coupling hole 230 may be formed in the substrate 220 and the substrate 220 may be coupled to the case 100 by inserting a screw or a pin into the coupling hole 230. The heat dissipation sheet 240 is disposed in contact with the substrate 220 on the lower surface of the substrate 220. The heat generated by the plurality of LEDs 210 is transferred through the substrate 220 to the heat dissipation sheet 240, Can be delivered. The heat-radiating sheet 240 may be a resin material or a metal material that can effectively dissipate heat. Also, the heat-radiating sheet 240 is formed of a material having adhesiveness and can be easily attached to the lower surface of the substrate 220.

≪ Reflector (400) >

22 is another embodiment of the reflection plate 400. Fig. Will be described with reference to Figs. 9, 10 and 22. Fig.

The reflector 400 may be formed of a resin material or a metal material having a high reflectance and is disposed on the substrate 220 and encloses the side wall 120 of the case 100. The resin material may include, for example, PET, PC, and PVC resin. The metal material may include, for example, an alloy including silver (Ag), silver (Ag) Alloys, stainless steel, and the like. The reflector 400 includes a bottom reflector 410 and a side reflector 420 extending from both sides of the bottom reflector 410 and includes fixing protrusions 430 extending outwardly from ends of the side reflectors 420 ).

The LED hole 411 is opened in the bottom reflector 410 of the reflector 400 and a plurality of LEDs 210 are inserted through the LED hole 411 to be exposed. Accordingly, the LED hole 411 may be formed to correspond to the number and arrangement of the plurality of LEDs 210. [ The LED hole 411 may be formed through a punching process or may be formed by various methods capable of forming an etching hole or the like. The side reflector 420 may be formed to be perpendicular to the bottom reflector 410, but it is preferable that the side reflector 420 has an inclination that tilts outward along the direction in which the side reflector 420 extends, as shown in FIGS. Do. In the case of inclination, the light generated by the plurality of LEDs 210 can be effectively reflected and emitted.

The fixing protrusion 430 of the reflection plate 400 is smaller than the width of the diffusion plate coupling groove 180 of the case 100 so that the fixing protrusion 430 can be slidably inserted into the diffusion plate coupling groove 180 And the reflector 400 may be fixed to the case 100. [

The side reflector 420 may extend from the bottom reflector 410 to the diffusion plate coupling groove 180 of the case 100. 22, the side reflector 420 may extend beyond the diffusion plate coupling groove 180 of the case 100 and extend beyond the side wall 120 of the case 100 .

Referring to FIGS. 9 and 10, a first electrical connector 421 may be formed at the lower end of the side reflector 420 of the reflector 400. The light emitting unit 200 may be electrically connected to the power control unit 20 through the first electrical connector 421 to receive power. A second electrical connection port (not shown) is formed at a lower end of the side wall 120 of the case 100 at a position corresponding to the first electrical connection port 421 of the reflection plate 400, And the power supply control unit 20 may be electrically connected through the second electrical connection port.

≪ Power control unit 20 &

23 is a perspective view of the power supply control unit 20, and Fig. 24 is a front view of the power supply control unit 20. Fig.

23 and 24, the power supply control unit 20 includes a body portion 21 and a second projection portion 22 at a lower end of the body portion 21. The body 21 may include a power supply unit (PSU) (not shown) for supplying power to the lighting apparatus 1 and a driving unit (not shown) for controlling and driving the light emitting unit 200. The sliding type coupling between the second projection 22 of the power supply control unit 20 and the power supply control unit coupling groove 152 of the case 100 has already been described and will not be described here.

The second protrusion 22 may be provided with a third coupling hole 23. The power control unit 20 can be fixed to the case 100 by inserting a coupling screw or a pin into the third coupling hole 23 after inserting the second projection 22 into the power control unit coupling groove 152 have. Of course, the second projection 22 may be coupled to the power supply control unit coupling groove 152 in a forced fit manner without the third coupling hole 23. The power supply control unit 20 includes a connection line 24 And may be electrically connected to the light emitting unit 200 to provide power and driving signals to the light emitting unit 200. The connection line 24 may connect the light emitting unit 200 and the power control unit 20 through the first electrical connection port 421 and the second electrical connection port (not shown). The power control unit 20 may be formed of a metal material or a resin material having good heat radiation characteristics.

Since the power supply control unit 20 includes various components such as a power supply unit (PSU) and a driving unit in the body portion 21, these components can be effectively protected from external impacts, moisture, and the like. In addition, the power supply control unit 20 can be easily coupled to or removed from the case 100, which facilitates replacement.

≪ Diffusion plate 300 >

1 to 3 and 5, the diffuser plate 300 is formed on the light emitting unit 200 to allow light emitted from the LED 210, which is a point light source, to be emitted through the diffuser plate 300 , And the surface of the diffusion plate 300 can be made a surface light source so as to have a uniform luminance.

Both side ends of the diffusion plate 300 may be inserted into the diffusion plate coupling groove 180 of the case 100 in a sliding manner along the first direction a shown in FIG. The material of the diffusion plate 300 may be, for example, glass, PMMA, PC, or the like.

 Since the diffusion plate 300 is formed not only on the front surface of the illuminating device 1 but only on the light emitting portion 200, the amount of use of the diffusion plate 300 can be reduced. Since the diffusion plate 300 is considerably narrow in width compared to the length and both sides of the diffusion plate 300 are supported by the case 100 along the longitudinal direction, the diffusion plate 300 is not sufficiently bent or stuck, There is no problem in the normal use of the battery 1.

FIG. 25 is a view showing one embodiment 300A of the diffuser plate 300, FIG. 26 is a view showing another embodiment 300B of the diffuser plate 300, and FIG. FIG. 28 is a view showing another embodiment 300C of the diffuser plate 300. FIG.

25 to 28, it can be seen that the diffuser plate 300 can have various shapes so as to variously control the light distribution of the emitted light of the light emitting unit 200.

However, if the illuminating device is fixed with the empty space between the illuminating device and the ceiling formed, it is not very good and the fixation of the illuminating device becomes unstable. In this case, it is practically difficult to cope with such a problem by making dozens or hundreds of specifications of a single lighting module 10 for aesthetic and stability, due to an increase in the manufacturing cost. Therefore, it is possible to provide a single lighting module 10 of a predetermined size as in the embodiments described so far, and the lighting device and the empty space of the ceiling can solve both aesthetics and fixability by using support frames 50 of various sizes . The member for forming the support frame 50 is formed to be elongated in one direction and is formed so that a cross section cut in a plane parallel to one direction has a uniform shape and a rectangular shape is formed by cutting the member into four pieces and connecting the corners A support frame 50 of a size can be formed. Therefore, the production process becomes very simple and it is possible to cope with various ceilings. In particular, if the length of the ceiling fixture 52 is different and the remaining specifications produce the same support frame 50 forming member, the ceiling can be almost perfectly different in size.
