Definitions
- the present invention relates to a lighting device, and more particularly to an LED surface lighting device having a plurality of LEDs arranged therein.
- a light emitting diode is a semiconductor element for converting electric energy into light.
- An electric bulb has a short life span. A longer time for use of the electric bulb allows the life span to be shorter. For this reason, the electric bulb is required to check and change cyclically. Therefore, there has been a problem of paying for the additional cost of changing and managing the electric bulb.
- the LED has advantages of low power consumption, a semi-permanent span of life, a rapid response speed, safety and an environment-friendliness.
- the LED is used as a light source for lighting devices, for example, various lamps used interiorly -and exteriorly, a liquid crystal display device, an electric sign and a street lamp and the like, as a result, is now increasingly taking the place of the electric bulb.
- the lighting device includes: a first case comprising a first bottom plate; a first and second side wall substantially vertically extending from both ends of the first bottom plate; a first louver inclined from the end of the first side wall with respect to a surface of the first side wall; a second louver inclined from the end of the second side wall with respect to a surface of the second side wall; a first light emitter seated on the first bottom plate; and a first diffuser being spaced apart from the first light emitter and having its both ends arranged at the ends of the first side wall and the second side wall; a second case comprising a second bottom plate; a third and fourth side wall substantially vertically extending from both ends of the second bottom plate; a third louver inclined from the end of the third side wall with respect to a surface of the third side wall; a fourth louver inclined from the end of the fourth side wall with respect to a surface of the fourth side wall; a second light emitter seated on the second bottom plate; and a second case
- each component is magnified, omitted or schematically shown for the purpose of convenience of description and clearness.
- the size of each component does not necessarily mean its actual size.
- a reference numeral is not added to a term of "a lighting device" it means that the lighting device includes lighting devices according to a first to a sixth embodiment.
- a lighting device 1 to be described in the following embodiments is formed in a particular manner. That is, the lighting device 1 is formed to include one single lighting module 10 and one power supply controller 20 or is formed to include a plurality of the single lighting modules 10 and at least one power supply controller 20. Since the lighting device 1 having various sizes is formed of one single lighting module 10 or is formed through combination of a plurality of the single lighting modules 10, a lighting device 1 having a desired size is not limited to be formed.
- a first single lighting module 10A, a second single lighting module 10B and a third single lighting module 10C will be described. There may be also a single lighting module having another shape.
- Fig. 1 is a cross sectional view of a first single lighting module 10A.
- Fig. 2 is a cross sectional view of a second single lighting module 10B.
- Fig. 3 is a cross sectional view of a third single lighting module 10C.
- the single lighting module 10 may include a case 100, a light emitter 200 seated on the bottom plate 110 of the case 100, a reflector 400 which is in contact with and disposed on the top surface of the light emitter 200 and a diffuser plate 300 spaced from and disposed over the light emitter 200.
- the first single lighting module 10A is used to form a lighting device of a first embodiment in which the two first single lighting modules 10A are coupled to each other in a direction perpendicular to the direction "a" in Fig. 7 . Otherwise, when a lighting device of a third embodiment is formed by coupling the three single lighting modules 10 having respectively one light emitter 200 in a direction perpendicular to the direction "a" in Fig. 13 , the first single lighting modules 10A are arranged at both sides of the three single lighting modules 10. Otherwise, when a lighting device of another embodiment (not shown) is formed by coupling four or more single lighting modules 10 having respectively one light emitter 200 in a direction perpendicular to the direction "a" in Fig. 13 , the first single lighting modules 10A are arranged at both sides of the single lighting modules 10.
- the case 100 of the first single lighting module 10A includes the bottom plate 110, a side wall 120 vertically extending from the both ends of the bottom plate 110, a louver 130 extending from the end of the side wall 120 and inclined at an obtuse angle with respect to the surface of the diffuser plate 300.
- a top plate 140 may be included instead of the louver 130.

- the first bracket coupler 151 is avoidably formed at the end of the louver 130 on one side of the case 100 of the first single lighting module 10A
- the ceiling fixed type frame 160 is not necessarily formed at the end of the louver 130 on the other side of the case 100.
- the first single lighting module 10A has the first bracket coupler 151 formed at the end of the louver 130 on only one side of the case 100.
- the first single lighting module 10 is different from the second single lighting module to be later described.
- the second lighting module 10B is used to form a lighting device of a fourth embodiment.
- the lighting device of the fourth embodiment includes only one single lighting module having one light emitter 200. Otherwise, when a lighting device of the third embodiment is formed by coupling the three single lighting modules having respectively one light emitter 200 in a direction perpendicular to the direction "a" in Fig. 13 , the second single lighting modules 10B may be arranged in the middle or at both sides of the three single lighting modules 10. Otherwise, when a lighting device of another embodiment (not shown) is formed by coupling four or more single lighting modules having respectively one light emitter 200 in a direction perpendicular to the direction "a" in Fig. 13 , the second single lighting modules 10B may be arranged in the middle or at both sides of the single lighting modules 10.
- the case 100 of the second single lighting module 10B includes the bottom plate 110, the side wall 120 vertically extending from the both ends of the bottom plate 110, the louver 130 extending from the end of the side wall 120 and inclined at an obtuse angle with respect to the surface of the diffuser plate.
- the top plate 140 may be included instead of the louver 130.
- the first bracket couplers 151 for interconnecting the single lighting modules 10 is formed at the ends of both louvers 130 of the case 100 of the second single lighting module 10B.
- the third single lighting module 10C is used to form a lighting device of a fifth embodiment shown in Fig. 16 .
- the lighting device of the fifth embodiment includes only one single lighting module having two light emitters 200.
- the third single lighting module 10C is used to form a lighting device of a sixth embodiment in which the two third single lighting modules 10C having respectively two light emitters 200 are coupled to each other in a direction perpendicular to the direction "a" of Fig. 19 .
- the third single lighting module 10C is used to form a lighting device of another embodiment (not shown) in which three or more two third single lighting modules 10C having respectively two light emitters 200 are coupled to each other in a direction perpendicular to the direction "a" of Fig. 19 .
- Fig. 4 is a perspective view of a lighting device 1A according to a first embodiment.
- Fig. 5 is a perspective view showing a cross-section of a lighting device 1A according to the first embodiment.
- Fig. 6 is a cross sectional view of a lighting device 1A according to the first embodiment.
- Fig. 7 is an exploded perspective view of a lighting device 1A according to the first embodiment.
- Fig. 8 is a cross sectional view of two cases 100 of a lighting device 1A according to the first embodiment.
- Fig. 9 is a perspective view showing a light emitter 200 and a reflector 400 are coupled to each other.
- Fig. 10 is an exploded perspective view of a light emitter 200 and a reflector 400.
- the lighting device 1 may include two first single lighting modules 10A, a power supply controller 20 located in a space 170 between the two first single lighting modules 10A, a bracket 30 for interconnecting the two first single lighting modules 10A, and additionally a side cover 40.
- the first single lighting module 10A used in the first embodiment may include the case 100, the light emitter 200 received by the case 100, and the diffuser plate 300 spaced from the light emitter 200, and additionally the reflector 400.
- the two second single lighting modules 10B may be also used to construct the first embodiment.
- the second single lighting module 10B has the first bracket couplers 151 formed at the ends of both louvers 130. Therefore, in forming the overall external appearance shown in the first embodiment, the appearance and function of the lighting device formed by coupling the two second single lighting modules 10B are little different from those of the lighting device formed by coupling the two first single lighting modules 10A.
- the light emitter 200 may be arranged on the bottom plate 110 of the case 100.
- the power supply controller 20 may be arranged in a space 170 between the two first single lighting modules 10A. That is, the space is formed by the louver 130 in which the first bracket coupler 151 are formed and by the side wall 120 connected to the louver 130.
- the lighting device 1 since the power supply controller 20 is stacked under the bottom plate 110 and arranged in a horizontal direction to the bottom plate 110 instead of in a vertical direction, the lighting device 1 has a thickness smaller than that of a usual lighting device.
- the ceiling of a building in which a ceiling buried type lighting device is disposed has generally a concrete structure.
- a structure called an M-BAR or a T-BAR is provided in a direction from the ceiling to the bottom surface of the building.
- Tex and the like are added to the M-BAR or T-BAR.
- the power supply controller 20 is stacked under the bottom plate 110 and arranged in a vertical direction, so that the thickness of the lighting device is often greater than 70 mm.
- electrical wiring and an air conditioning pipe and the like are arranged between the ceiling of the concrete structure and the M-BAR or T-BAR, it is often that a space for disposing a lighting device is very small. Therefore, when a usual directly downward type lighting device is buried and disposed on the ceiling due to the space constraint, it is required that the M-BAR be partly truncated or the lighting device be provided at an undesired position.
- the lighting device 1A according to the first embodiment has desirably a thickness of about 45 mm, it is possible to freely arrange the lighting device on the ceiling regardless of a narrow space and to easily and simply install the lighting device.
- the thickness of 45 mm is provided for illustration only in order to compare with a conventional lighting device. Therefore, the size of the lighting device 1A according to the first embodiment can be variously changed depending on numerical values of the thickness of the power supply controller 20 and/or the case 100 and the like.
- the lighting device 1 may have a rectangular shape extending in the first direction "a", the lighting device 1 may have various shapes in accordance with its installation position and its installation environment.
- Both louvers 130 of the light emitter 200 is inclined at an obtuse angle with respect to the surface of the diffuser plate 300 for the purpose of allowing light emitted from the light emitter 200 to be emitted and to have a desired light distribution angle and of alleviating glare from the light. If it is not possible to specify an angle based on the diffuser plate 300 due to no diffuser plate 300, the louver 130 may be specified to be extended from the end of the side wall 120 and to be inclined more outward than the side wall 120.
- the light emitter 200 may include LEDs 210, a substrate 220 on which the LEDs 210 are mounted, and a heat radiating sheet 240 arranged under the substrate 220.
- the substrate 220 may have a coupling hole 230 for coupling the case 100 to the substrate 220.
- the lighting device may further include the reflector 400.
- the reflector 400 reflects light emitted from the LED 210 to the outside of the lighting device 1 and covers the inner surface of the side wall 120 of the case 100. It is preferable that the reflector 400 covers not only the inner surface of the side wall 120 but the surface of the substrate 220 of the light emitter 200 other than an area on which the LEDs 210 are arranged.
- the power supply controller 20 may include a power supply unit (PSU) (not shown) and a driving part (not shown).
- the power supply unit (PSU) supplies electric power to the lighting device 1.
- the driving part controls, starts and operates the light emitter 200.
- the diffuser plate 300 is disposed apart from the light emitter 200 in the direction in which light is irradiated from the LED 210.

- the louver 130 may be replaced by the top plate 140.
- the case 100 is formed by assembling separately produced members, the members do not come in complete contact with each other but come in partial point contact with each other.

- the louver cut-off angle " ⁇ " is reduced, and the cover angle ⁇ is increased.

- louver 130 of Fig. 41 when the louver 130 is formed almost parallel with the side wall 120, the louver cut-off angle " ⁇ " is increased, and the cover angle ⁇ is reduced. This means that the glare does not occur at an angle larger than the louver cut-off angle " ⁇ ". However, since the louver cut-off angle " ⁇ " has been already excessively enlarged, the fatigue of the eyes caused by the glare may occur. Meanwhile, a light diffusion range is sufficiently increased, so that the irradiated area becomes larger.
- a lighting device giving a priority to the increase of the area to which light is irradiated is required to enlarge the louver cut-off angle " ⁇ ".
- a lighting device giving a priority to the prevention of the glare is required to reduce the louver cut-off angle " ⁇ ".
- louver cut-off angle " ⁇ " has a value between 0° and 90°.
- the louver cut-off angle " ⁇ " has a value within the aforementioned range, direct light from the diffuser plate 300 cannot be seen as the lighting device is viewed from one side to the other side of the diffuser plate 300.

- the thickness of the fixing protrusion 430 of the reflector 400 is less than the width of the diffuser plate coupling groove 180 of the case 100, the fixing protrusion 430 can be pushed in a sliding way into the diffuser plate coupling groove 180. Accordingly, the reflector 400 can be fixed to the case 100.
- the side reflector 420 may be formed extending from the bottom reflector 410 to the diffuser plate coupling groove 180 of the case 100. Meanwhile, as shown in Fig. 22 , the side reflector 420 may extend to pass through the diffuser plate coupling groove 180 of the case 100 and even the side wall 120 of the case 100.

- a second electrical connection hole (not shown) is formed at a location of the lower part of the side wall 120 of the case 100. The location corresponds to the location of the first electrical connection hole 421 of the reflector 400. Consequently, the light emitter 200 can be electrically connected to the power supply controller 20 through the first electrical connection hole 421 and the second electrical connection hole.

But for the third coupling hole 23, the second projection 22 may be coupled to power supply controller coupling groove 152 by using an interference fit.
- the power supply controller 20 also includes a connection line 24. The connection line 24 allows the power supply controller 20 to be electrically connected to the light emitter 200. Therefore, the power supply controller 20 is able to supply electric power and a driving signal to the light emitter 200.
- connection line 24 connects the light emitter 200 with the power supply controller 20 through the first electrical connection hole 421 and the second electrical connection hole.

- the power supply controller 20 is easily coupled to or separated from the case 100, thereby easily changing the power supply controller 20.
- the diffuser plate 300 is formed over the light emitter 200.
- the diffuser plate 300 allows light emitted from the LED 210 functioning as a point light source to be emitted through the diffuser plate 300.
- the surface of the diffuser plate 300 may actually function as a surface light source such that the emitted light obtains a uniform luminance.
- Both sides of the diffuser plate 300 is inserted in a sliding way into the diffuser plate coupling groove 180 of the case 100 in the first direction "a" shown in Fig. 5 , so that the diffuser plate 300 is coupled to the case 100.
- the material of the diffuser plate 300 may be, for example, a glass material, PMMA and PC and the like.
- the diffuser plate 300 Since the diffuser plate 300 is arranged over the light emitter 200 instead of on the entire surface of the lighting device 1, the amount of the used diffuser plate 300 can be reduced.
- the width of the diffuser plate 300 is considerably less than the length thereof. Both sides of the diffuser plate 300 is supported in the longitudinal direction thereof by the case 100. Therefore, the diffuser plate 300 is insignificantly bent or drooped, so that there is no problem in commonly using the lighting device 1.

- the diffuser plate 300 has a rectangular shape extending in the first direction "a", this is not necessarily required. It is often that the diffuser plate 300 usually has a flat shape. However, the diffuser plate 300 may have various shapes capable of controlling the light distribution of the light emitter 200.

In this case, more screws or pins are inserted into the first bracket coupler 151, the power supply controller coupling groove 152 and the second bracket coupler 153, so that the side cover 40 and the case 100 are coupled to each other.
- the side cover 40 Since the height and width of the side cover 40 may be formed to be equivalent to those of the case 100, the shape of the side cover 40 may be varied as shown in Figs. 29 and 30 . In addition, since the material of the side cover 40 may be the same as that of the case 100, the detailed description thereof will be omitted.

- the safety ring 38 prevents the provided lighting device 1 from being separated from the provided position or being damaged by falling down to the ground due to earthquake or other impacts, or prevents a person who is under the lighting device 1 from being hurt.
- a rope passing through the safety ring 38 is fixed within the ceiling. In this case, even though the lighting device 1 is separated from its provided position by impact, the rope fixed within the ceiling holds the safety ring 38 and prevents the lighting device 1 from falling down to the bottom surface. Therefore, the bracket 30 having the safety ring 38 includes not only an original function of connecting the single lighting modules, but an additional function of obtaining safety.
