In addition, when the term "illumination device" is not denoted with reference numerals, it indicates a lighting device encompassing the lighting devices 1, 2, 3, 4, 5, 6 according to the first to sixth embodiments.

Hereinafter, a lighting apparatus according to a first single lighting module, a second single lighting module, a third single lighting module, and embodiments will be described with reference to FIGS. 1 to 41.

Single lighting module

Unlike a conventional lighting device, the lighting device 1 according to the embodiment to be examined is formed in a unique manner. That is, one single lighting module 10 and one power control unit 20 are formed to form one lighting device 1 or a plurality of single lighting modules 10 and at least one power control unit 20 are formed. To form one lighting device 1. Since one or a plurality of single lighting modules 10 are combined to form lighting devices 1 of various sizes, there is no limitation in forming lighting devices 1 of a desired size.

The single lighting module 10 will describe three types of the first single lighting module 10A, the second single lighting module 10B, and the third single lighting module 10C, and a single lighting having a different shape. There may be modules.

1 is a cross-sectional view of the first single lighting module 10A, FIG. 2 is a cross-sectional view of the second single lighting module 10B, and FIG. 3 is a cross-sectional view of the third single lighting module 10C. 1 to 3 and 8, the single lighting module 10 may be disposed on the case 100, the light emitting part 200 mounted on the bottom plate 110 of the case 100, and an upper surface of the light emitting part 200. The light emitting unit 200 may include a reflecting plate 400 disposed in contact with the light emitting unit 200 and a diffusion plate 300 disposed above the light emitting unit 200.

The first single lighting module 10A is used when forming the lighting device of the first embodiment in which the first single lighting module 10A is coupled in a direction perpendicular to the direction of Fig. 7A. Alternatively, the single lighting module 10 including one light emitting unit 200 is used at both sides when forming the lighting apparatus of the third embodiment in which three single lighting modules 10 are coupled in a direction perpendicular to the direction of FIG. 13A. Or, it is used at both sides when forming a lighting device of an embodiment (not shown) in which at least four single lighting modules 10 including one light emitting unit 200 are combined in a direction perpendicular to the direction (a). .

1, 5, 6, and 8, the case 100 of the first single lighting module 10A has a bottom plate 110, and sidewalls extending vertically from both ends of the bottom plate 110. And a louver 130 extending from an end of the side wall 120 and inclined at an obtuse angle with respect to the surface of the diffuser plate 300. Like the second embodiment 1B shown in FIGS. 11 and 12, the upper plate 140 may be provided in place of the louver 130.

And at the end of one side louver 130 of the case 100 of the first single lighting module 10A, a first bracket coupling portion 151 for coupling the single lighting module 10 to each other is formed, and the other side louver 130 At the end, the ceiling fixing frame 160 is formed. However, the first bracket coupling part 151 must be formed at the end of the one side louver 130 of the case 100 of the first single lighting module 10A, but the ceiling fixing frame (at the end of the other louver 130) 160 may not be formed. As a result, the first single lighting module 10A has the first bracket coupling portion 151 formed only at one end of the one side louver 130, and is different in advantage from the second single lighting module to be described below.

The second single lighting module 10B is used when forming the lighting device of the fourth embodiment having only one single lighting module including one light emitting unit 200. Alternatively, when forming a lighting device of the third embodiment in which a single lighting module including one light emitting unit 200 is combined in a direction perpendicular to the direction of FIG. Can be used as a single lighting module on the side. Alternatively, when forming a lighting device of an embodiment (not shown) that combines four or more single lighting module including one light emitting unit 200 in the direction perpendicular to the direction (a) used as a single lighting module located in the center Or as a single lighting module on both sides.

2, 13, and 14, the case 100 of the second single lighting module 10B has a bottom plate 110, and sidewalls 120 extending vertically from both ends of the bottom plate 110. And a louver 130 extending from an end of the side wall 120 and inclined at an obtuse angle with respect to the surface of the diffusion plate. It may have a top plate 140 in place of the louver 130. A first bracket coupling part 151 is formed at the end of both side louvers 130 of the case 100 of the second single lighting module 10A to couple the single lighting module 10 to each other.

The third single lighting module 10C is used when forming the lighting apparatus according to the fifth embodiment shown in FIG. 16 having only one single lighting module including two light emitting units 200. Alternatively, it is used to form the lighting apparatus of the sixth embodiment in which two single lighting modules including two light emitting parts 200 are combined in a direction perpendicular to the direction (a) of FIG. 19. Or, it is used when forming a lighting device of an embodiment (not shown) in which three or more single lighting modules including two light emitting parts 200 are combined in a direction perpendicular to the direction (a).

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

First Example

4 is a perspective view of the lighting apparatus 1A according to the first embodiment, FIG. 5 is a perspective view showing a cross section of the lighting apparatus 1A according to the first embodiment, and FIG. 6 is an illumination according to the first embodiment. 7 is an exploded perspective view of the lighting device 1A according to the first embodiment, and FIG. 8 is a cross-sectional view of two cases 100 of the lighting device 1A according to the first embodiment. 9 is a perspective view of the light emitting unit 200 and the reflecting plate 400 coupled to each other, and FIG. 10 is an exploded perspective view of the light emitting unit 200 and the reflecting plate 400.

 4 to 8, the lighting device 1 includes two first single lighting modules 10A and is located in a space 170 between two first single lighting modules 10A. 20, a bracket 30 for coupling two first single lighting modules 10A, and an additional side cover 40. Referring to FIG. 1, the first single lighting module 10A used in the first embodiment may include a case 100, a light emitting part 200 and a light emitting part 200 spaced apart from the light emitting part 200. The plate 300 may be included and the reflector plate 400 may be additionally included.

4 to 8, although the first embodiment includes two first single lighting modules 10A, the first embodiment is configured using two second single lighting modules 10B. You may. Since the second single lighting module 10B has the first bracket coupling portion 151 at both ends of the louver 130, the two single lighting modules 10B are combined to form the overall appearance of the first embodiment. However, there is no significant difference in appearance and function from combining two first single lighting modules 10A.

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 partitioned by the louver 130 in which the first bracket coupling unit 151 is formed and the side wall 120 connected thereto in the two first single lighting modules 10A. Can be. In this case, since the power supply control unit 20 is stacked below the base plate 110 and not disposed in the vertical direction, the power control unit 20 is disposed in the horizontal direction on the base plate 110, so that the thickness of the lighting device 1 is higher than that of the conventional lighting device. Thinner.

The ceiling of the building where the ceiling light is to be installed usually has a ceiling of 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-BAR tex, etc. Will be attached. In general, the direct type lighting device installed on the ceiling of a building interior is disposed in the vertical direction by stacking the power control unit 20 under the base plate 110, so that the thickness is often more than 70mm. However, since the electrical wiring, air conditioning pipes, etc. are usually disposed between the ceiling of the concrete structure and the M-BAR or T-BAR, the space for installing the lighting device is often very small. Therefore, due to space constraints, when installing a conventional direct type lighting device embedded in the ceiling, there is a problem in that the M-BAR is partially cut off and installed inevitably, or the lighting position is unintentionally installed in an unintended position.

On the contrary, since the lighting device 1A according to the first embodiment has a thickness of about 45 mm, the lighting device can be freely disposed on the ceiling even when the installation space is small, and the installation is easy. Of course, the dimension of 45mm is a numerical value illustrated for the contrast with the existing lighting device, and therefore, the lighting device 1A according to the first embodiment according to the thickness of the power control unit 20 and / or the dimensions of the case 100 or the like. ) May vary in size.

The lighting device 1 may have a rectangular shape extending in the first direction a, but the shape of the lighting device 1 may be variously modified according to an installation position or an installation environment of the lighting device 1. have.

In order to emit light emitted from the light emitting unit 200 to have a desired light distribution angle and to mitigate glare from the light, the louvers 130 at both sides of the light emitting unit 200 may be diffused plate 300. Tilt at an obtuse angle to the plane of). If it is not possible to specify the angle with respect to the diffuser plate because it does not include the diffuser plate, the louver 130 may be specified to have an inclination that extends from the end of the side wall 120 to be wider outward than the side wall 120. Can be.

The inclination of the louver 130 may be variously modified according to the design of the lighting device 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 dissipation sheet 240 disposed under the substrate 220. . In addition, the substrate 220 may have a coupling hole 230 for coupling with the case 100.

In addition, the lighting device may further include a reflecting plate 400, the reflecting plate 400 reflects the light emitted from the LED 210 to the outside of the lighting device 1, the side wall 120 of the case 100 The inner surface of the The reflective plate 400 may not only cover the inner surface of the sidewall 120 but also surround the surface of the substrate 220 of the light emitting unit 200 except for the region where the LED 210 is disposed.

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

Referring to FIG. 5, the diffusion plate 300 is disposed to be spaced apart from the light emitting unit 200 in a direction in which light is emitted from the LED 210, and the light emitted from the LED 210 corresponding to each point light source is disposed. Surface light source is made through the diffuser plate 300, so that the emitted light of the light emitting unit 200 may have uniform luminance with respect to the surface of the diffuser plate 300.

The light emitting unit 200 is not formed on the front surface of the lighting device 1 and is disposed on the bottom plate 110 of the case 100. Therefore, even when using the same number of LEDs 210, the spacing between the LEDs 210 can be narrowed compared to the case of placing the LEDs 210 in front of the lighting device and the usage of the substrate 220 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 diffuser plate 300 to become a surface light source, an area where the light emitted from the adjacent LED 210 overlaps on the surface of the diffuser plate 300 must be created. In the end, this means that the LED 210 and the diffusion plate 300 should be sufficiently spaced apart. However, increasing the separation distance is not preferable because it means that the thickness of the lighting device 1 is increased, and in order to reduce the separation distance, the distance between the LEDs 210 should be reduced. As described above, since the light emitting unit 200 is not formed on the front surface of the lighting device 1 and is disposed on the bottom plate 110 of the case 100, the substrate 220 of the light emitting unit 200 also includes the case 100. Is limited to the width of the base plate 110. As a result, the spacing of the LEDs 210 disposed on the substrate 220 is naturally reduced, and the spacing between the LEDs 210 and the diffuser plate 300 required to make the surface light source is also reduced.

Therefore, the above-described structural advantages can provide a slim lighting device (1). In addition, when the light is irradiated to the irradiation surface from each LED in the absence of the diffusion plate 300, hot spots are generated. When the shape of the light source itself is irradiated on the irradiation surface as it is, the area where light is projected is distinctly distinguished from the area where the light is not. . In the case of not requiring concentrated lighting, and in general indoor lighting or outdoor lighting such as a street lamp, when a hot spot occurs, the uniformity of the irradiation surface is not preferable. When the surface lighting apparatus is used as in the embodiment, since the occurrence of hot spots is reduced as compared with the conventional lighting apparatus, the illuminance distribution of the irradiation surface is uniform and the eye fatigue is reduced.

2nd Example

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

11 is a cross-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 differs the most from the first embodiment in that the case 100 has a top plate 140 in place of the louver 130.

11 and 12, the second embodiment includes two first single lighting modules 10A, but alternatively, the second embodiment is configured by using two second single lighting modules 10B. You may. Since the second single lighting module 10B has the first bracket coupling portion 151 at both ends of the upper plate 140, the second single lighting module 10B combines two second single lighting modules 10B to form the overall appearance of the first embodiment. However, there is no significant difference in appearance and function from combining two first single lighting modules 10A.

Referring to FIG. 12, while the distance between the diffusion plate 300 and the light emitting unit 200 is maintained to be equal to that of FIG. 11, when the height of the sidewall 120 is higher than that of FIG. 11, the diffusion plate coupling groove 180 is provided. This is formed at the interruption of the side wall 120. In this case, due to the side wall 120 which is perpendicular to the base plate 110 and / or the diffuser plate 300 and extends higher than the first embodiment, the glare is more efficiently blocked than the first embodiment. Can be. However, the area of the area irradiated with light on the bottom surface may be reduced than in the first embodiment, or the uniformity of the illuminance distribution on the irradiation surface may be lower than in the first embodiment. Therefore, it will be preferable to install and use the second embodiment in a situation where glare prevention is required more preferentially than the area of the region to which light is irradiated and the illuminance distribution on the irradiated surface.

The third Example

Hereinafter, the lighting device 1C according to the third embodiment will be described in detail with reference to the components. In the description of the third embodiment, the same parts as those of the first embodiment are referred to the first embodiment, and redundant description thereof will be omitted.

And a power control unit 20 positioned in at least one space 170 of two spaces 170 formed between the first single lighting module 10A and the second single lighting module 10B. And, the single lighting module (11, 12) includes a bracket 30 for coupling between each other, and may further include a side cover (40). Here, the single illumination module 11 and 12 may include a case 100, a light emitting part 200 accommodated in the case 100, and a spaced apart diffusion plate 300, and may further include a reflector plate 400. . Since the case 100 of the first single lighting module 10A has already been described in the first embodiment, further description thereof will be omitted.

13 and 14 includes two first single lighting modules 10A and one second single lighting module 10B, but alternatively three second single lighting modules 10B. ) May also be used to construct the third embodiment. Since the first single lighting module 10A has only one first bracket coupling unit 151, the second single lighting module 10B may be used only at both sides when the plurality of single lighting modules are combined to form a lighting device. ) Has a first bracket coupling portion 151 at both ends of the louver 130, it can be used anywhere without covering the center or both sides of the lighting device. In addition, even when the three second single lighting module 10B is combined, there is no significant difference in appearance and function from the combination of the two first single lighting modules 10A and one second single lighting module 10B.

In the third embodiment, at least one power control unit 20 is required to drive a total of three light emitting units 200. According to the drawing, the power control unit 20 is two, but one power control unit 20 is three. Light emitting units 200 may be controlled. The location of one or more power control units 20 has been described.

Here, the case 100 of the second single illumination module 10B has a bottom plate 110, a side wall 120 extending vertically from both side ends of the bottom plate 110, and an end of the side wall 120. Extends from and has an inclined louver 130 at an obtuse angle with respect to the face of the diffuser plate. A first bracket coupling part 151 is formed at the end of both louvers 130 of the case 100 of the second single lighting module 10B to couple the single lighting modules 10 to each other.

Unlike the first, second, and third embodiments, since the fourth embodiment has only one single lighting module 10, the space 170 partitioned by two louvers 150 and sidewalls 120 connected thereto is provided. ) Therefore, the power control unit 20 is located on the outer side of one side wall 110 of one of the two side walls 120 of the case 100 of the second single lighting module 10B, and the first, second, and third embodiments In contrast, since the fixing of the power supply control unit 20 may be unstable, a hole is made in the side wall 110, and a hole is also made in the power supply control unit 20 so that the holes face each other, and then the screws or pins passing through the holes on both sides are removed. Through the case 100 and the power control unit 20 can be combined. However, even if a hole is not formed in the side wall 120 of the case 100, a separate bracket (not shown) that can be coupled to the power control unit 20 is formed on the side wall 120, such that the case 100 and the power control unit are formed. 20 may be combined.

Although illustrated, the first bracket coupling part 151 may be formed only at one end of one of the outer two louvers 130.

Referring to FIGS. 17 and 18, unlike the case 100 used in FIG. 16, a closed space defined by the outermost louver 130 and the outermost sidewall 120 and additional members spaced apart from each other is formed. have. When the additional member is formed in this way, the heat generated by the lighting device is transferred to the additional member, and the entire case may act as a heat radiator. As a result, the surface area of the heat radiator may be increased to increase the heat radiating effect. In order to further increase the heat dissipation effect due to this additional member, it is preferable to form the case 100 through extrusion molding.

Referring to FIG. 16, the lighting device 1E includes one third single lighting module 10C, and the inner two side walls 120 and two louvers 130 of the third single lighting module 10C. It may include a power control unit 20 located in the space 170 is partitioned by, and may further include a side cover (40). Here, the third single lighting module 10C includes a case 100, two light emitting parts 200 accommodated in the case 100, and two diffuser plates 300 spaced apart from each other, and further includes two reflector plates ( 400).

The case 100 of the third single lighting module 10C has two bottom plates 110, four side walls 120 extending vertically from both ends of the two bottom plates 110, and the side walls 120. It has a louver 130 extending from the end of the inclined to an obtuse angle with respect to the surface of the diffusion plate 300, the two inner ends of the louver 130 is connected to each other. In the absence of the diffusion plate 300, the louver 130 may extend from both ends of the side wall 120 and have a slope that is wider outward than the side wall 120.

Although not shown in FIGS. 16 to 18, the upper plate 140 may be provided in place of the louver 130 as in the second embodiment.

6th Example

Hereinafter, the lighting apparatus 1F according to the sixth embodiment will be described in detail with reference to the components. In describing the sixth embodiment, the same parts as in the fifth embodiment will be referred to the fifth embodiment, and redundant description thereof will be omitted.

19 is an exploded perspective view of the lighting device 1F according to the sixth embodiment, FIG. 20 is a perspective view of the lighting device 1F according to the sixth embodiment, and FIG. 21 is a lighting device 1F according to the sixth embodiment. ) Is a cross-sectional view.

The lighting device 1F according to the sixth embodiment uses the third single lighting module 10C including two light emitting parts 120 as in the lighting device 1E according to the fifth embodiment. Therefore, the case 100 of FIGS. 17 and 18 may be used for the lighting apparatus 1F according to the sixth embodiment.

19 to 21, the lighting device 1F includes two third single lighting modules 10C, and two inner sidewalls 120 and two inner sides of each third single lighting module 10C. It may include a power control unit 20 located in the space 170 partitioned by the louver 130, and may further include a side cover (40). Unlike in FIGS. 19 to 21, the power control unit 20 may be a lighting device including only one, not two. In this case, one power control unit 20 uses a total of 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 lighting module 10C. The third single light may be located in a space coupled by the bracket 30.

Like the fifth embodiment, the upper plate 140 may be replaced with the louver 130, and the exemplary embodiment having the upper plate 140 instead of the louver 130 is overlapped with the description of the fifth embodiment. Will be omitted.

In FIGS. 3 and 16, unlike the case 100 of the third single lighting module, when the first bracket coupling part 151 is formed only at one end of one of the two outer louvers 130, the third bracket is formed. Only two single lighting modules 10C can be combined, and more than three can not be combined. Therefore, in this case, there is no problem in implementing the sixth embodiment, but it is not possible to implement a lighting device having a larger size than the sixth embodiment.

Hereinafter, the illuminating device 1 is demonstrated centering on the component.

<Case (100)>

Description of the structure of the case 100 has already been discussed while describing the first to sixth embodiments, and thus the description thereof will be omitted.

See FIG. 6 and FIG. 8. When the single lighting module is adjacently coupled, the power control unit 20 is disposed in the space 170 partitioned by the louver 130 and the side wall 120, and the side wall 120 and the bottom plate 110 of the case 100 are disposed. When the second protrusion 22 formed at the lower end of the power control unit 20 in a sliding manner is inserted into the power control unit coupling groove 152 formed at the boundary, the case 100 and the power control unit 20 may be firmly coupled. .

On the other hand, the power control unit coupling groove 152 is shown to be formed to extend as long as the length of the case 100 along the first direction (a) shown in Figure 7, it does not necessarily have to take such a shape, extremely short length It may be extended only to form a thin plate that takes the shape of the alphabet "C" or "O". In addition, a hole is formed in the side wall of the case 100 without forming the power control unit coupling groove 152, and a hole or a hole is formed in a portion of the power control unit 20 opposite to the hole of the side wall 120, using a screw or a pin. The case 100 and the power control unit 20 may be combined. However, forming the power control unit coupling groove 152 in the case 100 is advantageous to produce through the extrusion molding method and can be combined with the case 100 and the power control unit 20 without additional screws or pins. It can be said to be a combination method.

There are two types of bracket coupling portions, the first bracket coupling portion 151 and the second bracket coupling portion 153. The case 100 may have first and second bracket coupling parts 151 and 153, and the first bracket coupling part 151 and the second bracket coupling part 153 may be connected to the bracket 30 to provide a single light. Modules can be firmly coupled to each other. In addition, the case 100 may be formed with a side cover coupling groove 154. Side cover coupling groove 154 is present for coupling with the side cover 40, the coupling method will be described in a separate table of contents.

The material of the case 100 may be a metal material or a resin material having good heat dissipation characteristics. In addition, an aluminum (Al) or silver (Ag) oxide film may be formed on the surface of the case 100 to ensure wear resistance, corrosion resistance, durability, and the like of the case 100, and to secure a good appearance of the lighting device 1. . In addition, the louver 130 is intended to prevent the glare for its original purpose, but the surface of the louver 130 is treated to reflect the surface well, or by attaching a reflective member to the surface to act as a reflector in addition to the anti-clear It can increase the light efficiency.

The case 100 may be assembled by separately manufacturing the bottom plate 110, the side wall 120, and the louver 130, but the entire case 100 may be integrally formed, for example, by extrusion molding. Can be formed. When forming the case 100 integrally (110), the side wall 120, the louver 130, as well as the diffusion plate coupling groove 180, the first and second bracket coupling parts (151, 153), power control unit coupling It is preferable that the groove 152 and the side cover coupling groove 154 are integrally molded at a time. The case 100 is integrally molded in the longitudinal direction as a whole. In addition, when the case 100 is integrally molded by extrusion or the like, the cross section of the case 100 cut into a plane perpendicular to the longitudinal direction has a consistent shape. For example, the shape of the cross section which cut the middle part of the case 100 and the cross section which cut the part near the edge | tip is the same. If the case 100 is integrally molded, the effort of assembling various members can be reduced, and the manufacturing process is simplified.

When molding the case 100, the diffusion plate coupling groove 180, the first and second bracket coupling portions 151 and 153, the power control unit coupling groove 152, the side cover coupling groove 154, and the like are described above. It is not always necessary to mold at the same time, and at least one member may be integrally molded when the case 100 is molded. For example, if necessary, the case 100 having only the bottom plate 110, the side wall 120, the louver 130, and the diffusion plate coupling groove 180 may be formed, and the bottom plate 110, the side wall 120, the louver may be formed. It is also possible to mold the case 100 in which only the 130 and the first and second bracket coupling parts 151 and 153 are formed.

Referring to FIG. 8, the diffusion plate coupling groove 180 may be formed at a boundary between the inner surface of the side wall 120 and the upper surface of the louver 130. 11 and 12, in the case where the upper plate 140 is provided in place of the louver 130, the diffusion plate coupling groove 120 has an inner side surface of the side wall 120 or a side wall close to the upper plate 140. It may be formed on the inner side of the (120).

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

Since the case 100 is integrally formed, heat can be effectively transmitted and released to the entire case 100, so that the lighting device can have good heat dissipation characteristics. Of course, in some embodiments, the louver 130 may be replaced with the upper plate 140. In more detail, in the case of manufacturing and combining the various members constituting the case 100 separately, partial contact between the members is not made in full surface contact with each other. Therefore, the heat transferred from the light emitting part 200 to the bottom plate 110 is not sufficiently transferred to the side wall 120, and the heat of the side wall 120 is not sufficiently transferred to the louver 130, thereby removing all the members of the case 100. It becomes impossible to use enough as a heat sink. On the other hand, when the case 100 is integrally formed through extrusion molding, since all of the cases are one member, the heat generated from the light emitting unit 200 or the power control unit 20 may cause the side wall 120 to be separated from the base plate 110. Through and evenly to the louver 130 is excellent heat dissipation effect.

The heat dissipation effect will be further described. As described in the fifth embodiment, an additional member constituting the case 100 may be formed at the lower end of the outermost louver 130, and the purpose of forming the additional member is to increase the surface area of the case 100 to increase the heat dissipation effect. Therefore, any shape that can increase the surface area of the case 100 to increase the heat dissipation effect can be taken. Therefore, 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, but a heat radiation hole may be formed, and irregularities are formed in the louver 130 or the side wall 120. It can also serve as a heat sink fin.

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 cross section, and may vary with a parabola or an arc. However, it is more important to have a louver limit angle θ than the shape of the louver 130 itself.

The lighting device in which the louver 130 is formed has a specific louver limit angle θ so that the diffuser 300 does not directly enter the field of view at the louver limit angle θ so that the glare is prevented. It is important to have an appropriate louver limit angle θ.

41 is a view for explaining louver limit angle θ and shielding angle α of the lighting apparatus according to the embodiment. Referring to FIG. 41, unlike the louver 130 of FIG. 41 to reduce the glare, when the louver 130 is formed to be substantially in line with the side wall 120, the louver limit angle θ becomes small and the shielding angle ( α) becomes large, which means that there is no glare at an angle larger than the louver limit angle θ. Therefore, a slight distance from the lighting device can reduce eye strain caused by glare. However, there is a disadvantage that the irradiation surface is narrowed by reducing the light diffusion range too much.

On the other hand, unlike the louver 130 of FIG. 41, when the louver 130 is formed to be almost parallel with the side wall 120, the louver limit angle θ becomes large and the shield angle α becomes small, which is thus louver. Although it means that there is no glare at an angle greater than the limit angle (θ), it means that the louver limit angle (θ) is already too large, so that no matter how far it is from the lighting device, the glare may occur and the eyes may be tired. Done. However, since the light diffusion range can be sufficiently widened, there is an advantage that the irradiation surface is wide.

Therefore, lighting devices with a greater emphasis on widening the area of the light-irradiated area should increase the louver limit angle (θ), and lighting devices with a greater focus on preventing glare are louver limitation angles (θ). Will have to be small.

The louver limit angle θ preferably has a value between 0 ° and 90 °, and when the louver limit angle θ has a value within this range, the line of sight from one side of the diffusion plate 300 toward the other side Direct light from the diffuser plate cannot be seen by this.

Since the light emitting unit 200 should be disposed on the bottom plate 110 of the case 100, the bottom plate 110 has a width and a length where the light emitting unit 200 can be disposed, and the side wall 120 and the louver 130 The diffusion plate coupling groove 180 may be formed at an abutting position, and the fixing protrusion 430 of the diffusion plate 300 and / or the reflective plate 400 may be fitted into the diffusion plate coupling groove 180. The diffusion plate coupling groove 180 may extend in the first direction a shown in FIGS. 7, 13, and 19.

When the fixing protrusion 430 of the diffusion plate 300 and / or the reflection plate 400 is pushed into the diffusion plate coupling groove 180 in a sliding manner, the side cover 40 is coupled to at least one end of the case 100. The diffuser plate 300 and / or the reflector plate 400 are sufficiently firmly fixed. Therefore, there is no fear that the diffuser plate 300 and / or the reflector plate 400 may be detached from the illumination device during installation and operation of the lighting device or during transportation.

1 to 3, the sidewall 120 of the case 100 is shown to extend in a vertical direction with the base plate 110, but it does not necessarily need to be vertical and may be substantially close to vertical. It may be formed to have an inclination that is wider toward the outside as it moves away. In addition, although not shown, irregularities are formed on the lower surface of the case 100, and the heat dissipation characteristics of the lighting apparatus may be improved by increasing the surface area of the case 100.

<Multiple light emitting units 200>

FIG. 9 is a perspective view of the light emitting unit 200 and the reflecting plate 400 coupled to each other, and FIG. 10 is an exploded perspective view of the light emitting unit 200 and the reflecting plate 400.

9 and 10, the light emitting unit 200 is disposed in contact with the substrate 220 under the plurality of LEDs 210, the substrate 220 on which the plurality of LEDs 210 are mounted, and the substrate 220. The heat dissipation sheet 240 may be included.

The plurality of LEDs 210 may include at least one light emitting diode (LED) emitting colors of red, green, blue, white, yellow, and the like. For example, the plurality of LEDs 210 may include red, green, and blue light emitting diodes (LEDs). In addition, the plurality of LEDs 210 may be formed by a combination of light emitting diodes (LEDs) emitting various color lights.

The 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 is a circuit printed on an insulator and may include an aluminum substrate, a ceramic substrate, a metal core PCB, a general PCB, and the like. The surface of the substrate 220 may be coated or painted in white or silver to increase reflection efficiency.

 The substrate 220 includes a circuit capable of driving the plurality of LEDs 210. As illustrated in FIGS. 9 and 10, the plurality of LEDs 210 may be arranged along rows and columns on the substrate 220, and may be arranged in various ways. In addition, the number of the plurality of LEDs 210 is also more or at least more than shown in the figure. However, if the LED 210 is too small, it is difficult for the lighting device to function as the surface light, so it is preferable to arrange the appropriate number of LEDs 210 in consideration of the function as the surface light.

A coupling hole 230 may be formed in the substrate 220. 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, and receives and releases heat generated from the plurality of LEDs 210 through the substrate 220, or to the entire case 100 Can be delivered. The heat dissipation sheet 240 may be made of a resin material or a metal material capable of effectively dissipating heat. In addition, the heat dissipation sheet 240 is formed of an adhesive material, and can be easily attached to the bottom surface of the substrate 220.

<Reflection board 400>

22 is another embodiment of the reflector plate 400. This will be described with reference to FIGS. 9, 10, and 22.

The reflector plate 400 may be formed of a resin material or a metal material having good reflectance. The reflector plate 400 may be disposed on the substrate 220 and surround the sidewall 120 of the case 100. The resin material may include, for example, PET, PC, PVC resin, and the like, and the metal material may include, for example, silver (Ag), an alloy containing silver (Ag), aluminum (Al), or aluminum (Al). Alloys, stainless steel, and the like. The reflecting plate 400 includes a bottom reflecting plate 410, and includes side reflecting plates 420 extending from both sides of the bottom reflecting plate 410, and a fixing protrusion 430 extending outward from an end of the side reflecting plate 420. ).

An LED hole 411 is drilled through the bottom reflector 410 of the reflector plate 400, and a plurality of LEDs 210 may be inserted and exposed through the LED hole 411. Accordingly, the LED holes 411 may be formed to correspond to the number and arrangement of the plurality of LEDs 210. The LED holes 411 may be formed through a punching process, and may be made through various methods for forming holes such as etching. The side reflection plate 420 may be formed to be perpendicular to the bottom reflection plate 410, but as shown in FIGS. 1 to 3, it is preferable to have an inclination inclined outward in a direction in which the side reflection plate 420 extends. Do. In the case of having an inclination, the light generated by the plurality of LEDs 210 may be effectively reflected and emitted.

Since the thickness of the fixing protrusion 430 of the reflector plate 400 is smaller than the width of the diffusion plate coupling groove 180 of the case 100, the fixing protrusion 430 may be pushed into the diffusion plate coupling groove 180 by sliding. The reflective plate 400 may be fixed to the case 100.

The side reflection plate 420 may be formed to extend from the bottom reflection plate 410 to the diffusion plate coupling groove 180 of the case 100. On the other hand, as shown in Figure 22, the side reflector plate 420 may extend beyond the diffusion plate coupling groove 180 of the case 100, may extend beyond the side wall 120 of the case 100. .

9 and 10, a first electrical connector 421 may be formed at the bottom of the side reflector plate 420 of the reflector plate 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. Meanwhile, a second electrical connector 121 (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 connector 421 of the reflector plate 400. The light emitting unit 200 and the power control unit 20 may be electrically connected through the electrical connectors 421 and 121.

<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. As shown in FIG.

Referring to FIGS. 23 and 24, the power control unit 20 includes a body portion 21 and a second protrusion 22 at the bottom of the body portion 21. The body portion 21 may include a power supply unit (PSU) (not shown) for supplying power to the lighting device 1, and a driver (not shown) for controlling and driving the light emitting unit 200. Since the sliding type coupling of the second protrusion 22 of the power control unit 20 and the power control unit coupling groove 152 of the case 100 has already been described, it will be omitted.

In addition, a third coupling hole 23 may be formed in the second protrusion 22. After inserting the second protrusion 22 into the power control unit coupling groove 152, a coupling screw or a pin or the like may be inserted into the third coupling hole 23 to fix the power control unit 20 to the case 100. have. Of course, even without the third coupling hole 23, the second protrusion 22 may be coupled to the power control unit coupling groove 152 in an interference fit manner. In addition, the power control unit 20 may include a connection line 24. Thus, the light emitting unit 200 may be electrically connected to provide a power and a driving signal 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 connector 421 and the second electrical connector 121. The power control unit 20 may be formed of a metal material or a resin material having good heat dissipation characteristics.

Since the power control unit 20 includes various components such as a power supply unit (PSU) and a driving unit in the body portion 21, the power control unit 20 may effectively protect these components from external impact, moisture, and the like. In addition, the power control unit 20 can be easily coupled or separated with the case 100, there is an advantage that easy replacement.

<Diffusion plate 300>

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

Both side ends of the diffusion plate 300 may be inserted into the diffusion plate coupling groove 180 of the case 100 along the first direction a shown in FIG. 5 to be coupled to the case 100. The material of the diffusion plate 300 may be, for example, glass, PMMA, PC, or the like.

 Since the diffusion plate 300 is not formed on the entire surface of the lighting device 1 and is formed only on the light emitting unit 200, the amount of the diffusion plate 300 may be reduced. The diffuser plate 300 is considerably narrower than its length, and since both sides of the diffuser plate 300 are supported by the case 100 along the longitudinal direction, the warpage and deflection of the diffuser plate 300 is insignificant. There is no problem in normal use of (1).

FIG. 25 is a view showing an embodiment 300A of the diffusion plate 300, FIG. 26 is a view showing another embodiment 300B of the diffusion plate 300, and FIG. 27 is another view of the diffusion plate 300. Another embodiment 300C is shown, and FIG. 28 shows another embodiment 300D of the diffuser plate 300.

25 to 28, it can be seen that the diffusion plate 300 may have various shapes so as to variously control the light distribution of the emission light of the light emitting unit 200. For example, referring to FIG. 25, the diffusion plate 300A may have a planar shape. Referring to FIG. 26, the diffusion plate 300B may have a shape having two parabolic surfaces. Referring to FIG. 27, the diffusion plate 300C may have a convex parabolic surface and may have a concave surface. Referring to FIG. 28, the incident surface of the diffusion plate 300D may be flat and the emission surface may be formed convexly.

The diffusion plate 300 preferably has a rectangular shape extending along the first direction a, but it is not necessary to take such a shape. In addition, although the diffusion plate 300 generally takes a planar shape, the diffusion plate 300 may have various shapes in which light distribution of the light emitting part 200 can be controlled.

The side cover 40 may prevent moisture, dirt, and the like from penetrating into the case 100, may increase rigidity of the lighting device, and the light emitting unit 200 and the power control unit 20 accommodated in the case 100. ) Can be fixed. The side cover 40 may include a plurality of coupling holes 41, and the case 100 may also include a plurality of side cover coupling grooves 154.

After opposing the cover cover coupling groove 154 of the case 100 and the coupling hole 41 of the cover cover 40, the screw or pin passing through the cover cover coupling groove 154 and the coupling hole 41 is fastened. The case 100 and the side cover 40 may be coupled to each other. The side cover 40 may prevent dust or dirt from flowing into the case 100, and may further increase the rigidity of the case 100. After arranging the plurality of coupling holes 41 and the plurality of cover cover coupling grooves 154 to be visible, a screw or a pin or the like passes through both the plurality of coupling holes 41 and the plurality of cover cover coupling grooves 154. By combining, the side cover 40 may be coupled to the case 100. The coupling hole 41 of the side cover 40 does not necessarily have to be drilled only at a position corresponding to the side cover coupling groove 154, but the first bracket coupling portion 151 of the case 100 and the power control unit coupling groove ( 152, and may be drilled at a position corresponding to the second bracket coupling part 153. In this case, more screws or pins may be inserted into the first bracket coupling unit 151, the power control unit coupling groove 152, and the second bracket coupling unit 153 to couple the side cover 40 to the case 100. have.

Since the height and width of the side cover 40 may be formed to correspond to the case 100, the shapes may be different from each other as shown in FIGS. 29 and 30. In addition, the material of the side cover 40 may be the same as the material of the case 100, detailed description thereof will be omitted.

<Bracket 30>

Referring to FIGS. 31 and 32, the brackets 30A and 30B have a fixing plate 31 and extend from one end of the fixing plate 31 to be coupled to the first bracket coupling part 151 of the case 100. It has the engaging member 32, and has the safety ring 38 extended from the end of the fixed plate 31. The lighting module coupling member 32 and / or the safety ring 38 may be formed at one end as well as the other end of the fixing plate 31.

6 and 11, the coupling method of the case 100 and the bracket 30 in the first and second embodiments can be seen. The fixed plate 31 is slidably pushed into the second bracket coupling portion 153 of the case 100, and the lighting module coupling member 32 has a through hole so that it is illuminated through a screw or pin passing through the through hole. The module coupling member 32 and the first bracket coupling portion 151 of the case 100 are coupled.

33 and 34, the shape of the first bracket coupling part 151 of the case 100 is different when compared with FIGS. 6 and 11. However, the coupling method is the same, and the fixed plate 31 is pushed into the second bracket coupling portion 153 of the case 100 in a sliding manner, and the lighting module coupling member 32 has a through hole so as to pass through the through hole. The first bracket coupling portion 151 of the lighting module coupling member 32 and the case 100 is coupled through a screw or a pin.

35 and 36, compared with the bracket 30A shown in FIGS. 33 and 34, the fixing plate 31 and the safety ring 38 have no difference, and the shape of the lighting module coupling member 32 is different. And there is a difference in the coupling manner with the first bracket coupling portion 151 of the case 100. The lighting module coupling member 32 does not have a through hole through which screws or pins can be fastened, and instead, the lighting module coupling member 32 can walk by supporting the first bracket coupling portion 151 of the case 100. It can take the shape of the hanging hook. Of course, in this case, the first bracket coupling part 151 used has a different shape from the first bracket coupling part 151 shown in FIGS. 6, 11, 33, and 34. Unlike the bracket 30A shown in FIGS. 31, 33 and 34, the bracket 30B shown in FIGS. 32, 35 and 36 may be coupled to the first bracket coupling part in a sliding manner without screws or pins. have.

The first bracket coupling part 151 is formed at the end of the louver 130 of the case 100, and the second bracket coupling part 153 is formed at the louver 130 or the side wall 120. Meanwhile, when the upper plate 140 is provided instead of the louver 130 as shown in the second embodiment illustrated in FIGS. 11 and 12, the first bracket coupling part 151 is formed at the end of the upper plate 140 of the case 100. The second bracket coupling part 153 is formed on the side wall 120.

The safety ring 38 is for preventing the injured person from being injured by falling from the installation position or falling on the floor due to an earthquake or other impact, or from falling to the person under the lighting device 1. . When the rope is fixed to the inside of the ceiling by passing the wire through the safety ring 38, the rope fixed inside the ceiling catches the safety ring 38 even when the lighting device 1 is shocked and detached from the installation place. The fall of the lighting device 1 to the surface can be prevented. Therefore, the bracket 30 having the safety ring 38 is formed in addition to the original purpose of connecting a single lighting module has a further function to ensure safety.

The bracket 30 is not to be combined with only one along the longitudinal direction of the case 100, a plurality of coupling may be combined to increase the coupling rigidity between the single lighting module, or to ensure safety.

FIG. 37 shows another example 30C of the bracket 30, and FIG. 38 shows a structure in which the bracket 30C connects the single lighting modules 10 to each other.

Referring to FIG. 38, a plurality of brackets 30C may be formed on the outer surface of the lighting device 1, that is, the case 100. The bracket 30C having such a shape does not have a separate first bracket coupling part 151 such as the case 100 shown in FIGS. 17 and 18 or the case 100 shown in FIG. 38. It can be used when joining together. The bracket 30C has two surfaces bent at right angles, and the two surfaces include a first surface 33 coupled to an outer surface of the case 100, an external support member such as a ceiling or a wall surface, or a case. It may include a second surface 35 coupled to the outer surface of the (100). The first surface 33 has a first coupling hole 34, the second surface 35 has a second coupling hole 36, and a coupling screw or the like is provided in the first and second coupling holes 34 and 36. It can be inserted to couple a single lighting module together or to couple the lighting device 1 to an external support member. In addition, the bracket 30C may be formed integrally with the case 100.

<Support frame 50>

FIG. 42 is a perspective view of the support frame 50, FIG. 43 is a cross-sectional view of the support frame 50, FIG. 44 is a cross-sectional view showing a coupling state between the support frame 50 and the ceiling M-BAR, and FIG. 45 is a support It is sectional drawing which shows the coupling state of the frame 50 and T-BAR of a ceiling.

42 to 45, the support frame 50 extends from the inner surface of the frame body 51 and the frame body 51 surrounding the outer surface of the case 100 to support the load of the case 100. The case supporting part 53, and extends from the outer surface of the frame body 51 includes a ceiling fixing part 52 fixed to the ceiling. As shown in FIG. 43, the frame body 51 may have an empty space therein to reduce weight.

The case support part 53 contacts the end of the louver 130 of the case 100 to support the load of the members constituting the other lighting device including the case 100. In addition, in order to prevent the members of the lighting device other than the supporting frame 50 from falling through the opening of the supporting frame 50, the side cover 40 corresponds to the side cover 40 rather than the length between the outermost louvers 130 of the lighting device. It is preferable to shorten the length between the case support parts 53 in the position to be rather short. However, if it is shorter than necessary, the inclined surface of the louver 130 is covered, which is not preferable. Therefore, it is preferable to form the length between the case support parts 53 so that it does not cover the inclined surface 130 of a louver.

The ceiling fixing unit 52 may not only fix the lighting device to the ceiling, but when there is a gap between the case 100 and the ceiling where the case is installed, the ceiling fixing unit 52 may cover the gap to make the aesthetics beautiful. In addition, the ceiling fixing unit 52 may have a ceiling coupling groove (54).

43 and 44, the lighting device may be fixed to the ceiling by fastening screws to pass through the ceiling coupling groove 54 and the TEX and the M-BAR.

43 and 45, under the load of the lighting device itself, the lighting device is fixed to the ceiling while the lower surface of the ceiling fixing unit 52 is in contact with the T-BAR. In this case, the ceiling fixing portion 52 does not necessarily have to have the ceiling coupling groove 54, but considering that the ceiling fixing portion 52 is installed not only in the T-BAR but also in the M-BAR, the ceiling fixing portion 52 has the ceiling coupling groove 54. It is preferable.

Particularly useful of the support frame 50 is that it can flexibly cope with various installation environments. According to each country or each ceiling structure, the area of the ceiling where the lighting device is installed varies. In the various embodiments presented so far, various sizes of lighting devices are implemented through the combination of a single lighting module 10. However, if the lighting device is fixed with an empty space formed between the lighting device and the ceiling, the appearance is not good, and the fixing of the lighting device is also unstable. In this case, for aesthetics and fixability, it is virtually difficult to cope with such a problem by making tens or hundreds of specifications of a single lighting module 10 due to an increase in manufacturing cost. Therefore, as shown in the present embodiment, there are provided a single lighting module 10 of a predetermined size, and the empty space of the lighting device and the ceiling can be solved both aesthetics and fixability by using the support frame 50 of various sizes. . The member forming the support frame 50 is formed to be elongated in one direction, and the cross section cut in a plane parallel to one direction is formed to have a consistent shape. The support frame 50 of the size can be made. Therefore, the production process is very simple, there is an advantage that can respond to a variety of ceilings. In particular, if only the length of the ceiling fixing part 52 and the other standard produces a member for forming the same support frame 50 can almost correspond to the ceiling of various sizes.
