Like reference numerals refer to like elements throughout the specification.

Hereinafter, embodiments will be described in detail with reference to the drawings.

1 is a view showing a state in which a lighting apparatus 10 according to an embodiment of the present invention is installed on a ceiling.

Referring to FIG. 1, in the embodiment, the lighting apparatus 10 is generally inserted into the ceiling. The lighting device 10 may be inserted directly into the ceiling 40, but may be inserted into the ceiling using a troffer 20 as in the embodiment.

Here, the trough 20 is installed in a home, an office, a factory, or the like to facilitate the coupling of the lighting apparatus 10 and provide a space in which the lighting apparatus 10 is located. In addition, the trough 20 can be connected to an external power source to supply power to the lighting apparatus 10. [

In particular, the trough 20 has a size that is standardized so that the standardized lighting apparatus 10 is coupled.

For example, the trough 20 may form a receiving space 210 in which the illuminator 10 is located and may have an open shape on one side. Specifically, the trough 20 can be formed in a rectangular shape.

FIG. 2 is an exploded perspective view of a lighting apparatus according to an embodiment of the present invention, and FIG. 3 is an assembled perspective view of a lighting apparatus according to an embodiment of the present invention.

2 and 3, the lighting apparatus 10 is an apparatus for generating a light source 120 by converting electric energy into light energy.

For example, the lighting device 10 includes a case 110 and a flexible hanger 150 where at least one source of light 120 and a source of light 120 are located.

The case 110 is received in the receiving space 210 of the trough 20 or the hole 410 formed in the ceiling 40. [ Therefore, the case 110 may have a shape corresponding to the shape of the hole 410 formed in the trough 20 or the ceiling 40. Specifically, one side of the case 110 is exposed to the lower portion of the trough 20.

For example, the case 110 may have a shape that guides the light source 120 generated from the light source 120 to the lower side.

Specifically, the case 110 may have a shape in which the lower portion is opened and the width of the case 110 is expanded as it goes from the upper portion to the lower portion. Of course, the inner surface of the case 110 may be coated with at least one of Al, Ag, Al alloy, and Ag alloy.

The light source 120 converts the electrical energy into light energy. For example, the light source 120 includes at least one light emitting source 120, and the light emitting source 120 may be divided into a plurality of groups. The light emitting source 120 may be a light emitting diode 120 diode chip that emits a light source 120 of any one of red, green, and blue.

In more detail, the light source 120 may include a plurality of light sources 120 on a circuit board formed in a long direction.

The light source 120 is located on one side 111 of the case 110 and the light source 120 generated by the light source 120 is guided downward by the case 110. Specifically, the circle of the light source 120 is coupled to the lower surface of the one side 111 of the case 110.

More specifically, the case 110 includes a first surface 111 on which the light source 120 is located, a slope 112 having a shape extending downward to guide the light generated from the light source 120 downward, .

The power supply unit 130 may be positioned on one side 111 of the case 110. The power supply unit 130 supplies driving power to each component constituting the lighting apparatus 10. [

For example, the power supply unit 130 receives AC power of 110V to 220V and can supply DC power of any one of 25V, 50V, and 100V to an illumination driver (not shown). In addition, the power supply unit 130 can supply DC power of 3V to the communication module (not shown) using the inputted AC power.

Specifically, the power supply unit 130 may be positioned between the circles of the light sources 120 positioned in multiple rows. Of course, the power supply unit 130 may be covered by the power cover 140. [

The power cover 140 covers the power source unit 130 to prevent the light generated by the circles 120 from being absorbed into the power source unit 130.

The power cover 140 is positioned between the circles of the light sources 120 and guides the light source 120 generated from the light source 120 to the lower side of the case 110. The outer surface of the power cover 140 may be coated with a reflective material.

The illumination device 10 may further include a diffusion cover 150 for converting light supplied from the light sources 120. [ The diffusion cover 150 alleviates the concentration of light generated in the light source 120 circles. Specifically, the diffusion cover 150 may cover one area below the case 110 so as to cover at least the light source 120 circles.

For example, the diffusion cover 150 may have a concavo-convex shape to diffuse light, or may include a diffusion material that scatter or reflect light. However, the present invention is not limited thereto.

In general, in the process of coupling the lighting device 10 to the trough 20, the lighting device 10 is fixed to the trough 20, and the lighting device 10 and the trough 20 The lighting apparatus 10 is buried in the trough 20 after electrically connecting.

Particularly, it is general that the lighting device 10 and the electric cable 41 of the trough 20 (or the ceiling 40) are embedded between the one side 111 of the lighting device 10 and the trough 20 to be. Therefore, the operator fixes the lighting apparatus 10 to the near side of the trough 20 with the help of the auxiliary worker or the auxiliary machine during the electrical work of the lighting apparatus 10 and the trough 20, The lighting apparatus 10 is completely fixed to the trough 20 after the electrical work for electrically connecting the trough 10 and the trough 20 to each other.

Therefore, there is a disadvantage that the work for fixing the lighting apparatus 10 to the trough 20 is not easy.

In order to solve the above-mentioned disadvantage, an embodiment of the present invention requires a device for fixing the lighting device 10 to the ceiling 40. The embodiment employs the flexible hanger 150 to solve this problem.

5 is a cross-sectional view taken along the line AA of FIG. 4. FIG. 6 is a view showing a bent state of the flexible hanger according to an embodiment of the present invention. FIG. 4 is a plan view of the lighting apparatus according to an embodiment of the present invention, Fig.

The flexible hanger 150 is formed in the case 110 and is hooked to an external structure at the time of installation. That is, the flexible hanger 150 is formed in the case 110 to fix the lighting apparatus 10 and the ceiling 40 or the trough 20 to each other. The flexible hanger 150 is secured to the cable 40 fixed to the ceiling 40 or the trough 20.

The flexible hanger 150 may be formed of a separate member from the case 110. Preferably, the flexible hanger 150 is formed by cutting a part of the one side 111 of the case 110. [ The flexible hanger 150 is bent so as to protrude from one surface 111 of the case 110. Of course, at this time, one surface 111 of the case 110 is formed as a plate.

Specifically, the flexible hanger 150 is bent so that one surface 111 of the case 110 is cut out and protruded to an upper portion of one surface of the case 110. That is, the flexible hanger 150 is formed by cutting one side 111 of the case 110 and bending in one direction, and the cable 41 fixed to the ceiling 40 or the trough 20 is fixedly protruded.

For example, the flexible hanger 150 includes a ring 151 that is hooked to an external structure, and a connecting portion 152 that connects one end of the ring 151 to one side 111 of the case 110 .

The ring 151 is hooked to an external structure. The outer structure may be a cable 41 having one end fixed to the ceiling 40 or the trough 20.

The ring 151 has a structure in which an external structure or a cable 41 is hooked. For example, as shown in Fig. 4, the annular portion 151 may include a through hole 151a through which the cable 41 passes. As another example, the hook 151 may have a structure in which one side is opened in a hook shape.

The annular portion 151 is a part of one surface 111 of the case 110 and the boundary of the annular portion 151 is formed at one side 111 of the case 110 by cutting. More specifically, the ring 151 is connected to one side 111 of the case 110 at one end, and the other region except for one end of the ring 151 can be cut at one side 111 of the case 110 .

More specifically, the ring 151 is disconnected by one side 111 of the case 110 and the cutting hole 153 in three directions when viewed from the top of one side 111 of the case 110, And may have a shape connected to one surface 111 of the case 110. At this time, a portion of the ring 151 connected to the one surface 111 of the case 110 becomes a portion bent when the ring 151 is bent. That is, the cutting hole 153 has a " C "shape and defines the boundary of the ring 151. [

Even if the ring 151 is cut on one side 111 of the case 110, if the ring 151 is located on the same plane as the one side 111 of the case 110, 111). Therefore, in the embodiment, the annular portion 151 is positioned so as to protrude upward from one surface 111 of the case 110.

Specifically, all or a part of the area of the ring 151 protrudes upward from one surface 111 of the case 110. At least a part of the upper surface of the ring 151 may be located above the upper surface of the one surface 111 of the case 110. Therefore, the user can easily grasp and fold the hook 151 positioned above the one side 111 of the case 110. The end of the ring 151 facing the connection part 152 may be positioned above the one side 111 of the case 110. [

The connection part 152 connects one end of the ring 151 and one side 111 of the case 110. [ Specifically, the connection portion 152 may be defined as a portion where one end 111 of the case 110 meets one end of the ring 151. The three directions of the ring 151 are separated by one side 111 of the case 110 and the cutting hole 153 as viewed from above the one side 111 of the case 110, The connecting portion 152 may be a portion connected to the one surface 111 of the case 110 at the hook 151. In this case,

The connecting portion 152 is a rotation origin when the ring 151 protrudes from one surface 111 of the case 110. That is, the hook 151 is bent at one side 111 of the case 110 with respect to the connecting portion 152.

Stress may concentrate on the connection portion 152 during the process of bending the connection portion 152 to break the connection portion 152 or bend the portion other than the connection portion 152. Therefore, a bending hole 152a defining a bending reference line of the connection part 152 may be formed in the connection part 152. [

At least one bending hole 152a is formed at a boundary between one side 111 of the case 110 and the annular portion 151. [ The bent hole 152a is formed through one side 111 of the case 110. [ A plurality of bending holes 152a may be formed along the boundary between the one surface 111 of the case 110 and the hook 151. The bending hole 152a defines a bending reference line at which the connection portion 152 is bent to reduce stress concentration and to prevent the connection portion 152 from being bent.

6, the annular portion 151 is bent along the bending hole 152a and protruded from one surface 111 of the case 110. As shown in FIG.

Further, the case 110 may further include a plurality of fastening portions 115 through which fastening members pass.

The plurality of fastening portions 115 may be arranged on one surface 111 of the case 110 in a plurality of areas. A plurality of fastening portions 115 are formed on one surface 111 of the case 110 and there is an advantage that the lighting devices 10 of various sizes can be manufactured as one case 110. [ In addition, various peripheral devices (power supply unit, communication module, etc.) can be easily coupled to the one surface 111 of the case 110.

For example, the fastening part 115 may be a hole formed through one surface 111 of the case 110. The fastening part 115 may protrude from one surface 111 of the case 110.

7 is a view illustrating a use of the flexible hanger according to an embodiment of the present invention.

Referring to FIG. 7, when the lighting apparatus 10 of the embodiment is to be embedded in the ceiling 40, the user flexes the flexible hanger 150 formed by cutting one side 111 of the case 110.

Thereafter, the operator fixes the cable 41 fixed to the ceiling 40 to the flexible hanger 150 bent at one side 111 of the case 110. Thus, the lighting device 10 is fixed at a certain distance or near the ceiling 40. [ At this time, after the worker completes the electric work of the lighting apparatus 10, the lighting apparatus is buried in the hole of the ceiling 40.

8 is a view showing a flexible hanger according to another embodiment of the present invention.

Referring to FIG. 8, the flexible hanger 150 of another embodiment is different from the embodiment of FIG. 4 in the shape of the ring 151.

One end of the hook is connected to one side 111 of the case 110 and the other end of the hook is connected to the side of the case 110 by the cutout hole 153. [ And is incised at one face 111 thereof.
