Description

LIGHTING DEVICE

The present invention relates to a luminaire. More particularly, the present invention relates to a luminaire capable of easily and firmly fixing an LED or the like.

Generally, incandescent lamps are used for office or home use. The incandescent lamp has a disadvantage in that it consumes a lot of power and has a short life span as compared with its brightness. Recently, incandescent lamps are gradually being replaced by LEDs (light emitting diodes).

An LED is a semiconductor made of Ga (gallium), P (phosphorus), or As (arsenic). LEDs have the characteristics of a diode, and when applying voltage to an LED, they can take on a variety of colors. LEDs have a longer life span than incandescent lamps, have a faster response speed, and can be manufactured in various shapes. Therefore, incandescent bulbs used in offices or households are gradually being replaced by LEDs. However, it is necessary to replace the incandescent lamp with an LED by using the same fixing mechanism as that of a conventional incandescent lamp.

An incandescent lamp or the like can be conveniently replaced by an LED or the like and can be manufactured at a low cost.

An exposure fixation portion communicating with the groove is formed on a side surface of the wall portion, and the fixation member includes: i) a first fixation portion which is fixed while being exposed through the exposure fixation portion, and ii) And a second fixing part extending in a direction passing through the ceiling and partially inserted into the groove. Further comprising an elastic member which is installed on the first fixing part and extends long in a direction intersecting the direction of penetrating the ceiling and which extends over the inside of the ceiling to fix the light source casing member to the ceiling, And the width of the first fixing part may be 20 mm to 50 mm.

The lamp according to an embodiment of the present invention may further include a diffusion plate disposed between the light source seating member and the light source casing member to diffuse the light emitted from the light source. The light source seating member includes: i) a light source seating portion in which the light source is seated and fixed; ii) a side portion connected to the light source seating portion and opposed to the wall portion; and iii) a supporting portion connected to the side portion and positioned on the light source casing member. The diffuser plate can be positioned under the support. A fixing protrusion for fixing the light source seating member is formed on the side surface, and the supporting portion can be guided along the screw groove formed along the side surface of the fixing protrusion. The inclination angle of the fixing protrusion may be 10 to 40 degrees.

The wall portion may comprise a second wall, i) a first wall, and ii) a second wall connected to the first wall and having a groove, the wall having a thickness greater than the thickness of the first wall. The second wall may protrude further away from the center of the light source casing member than the first wall. The groove has a circular arc shape, the thickness of the fixing member is smaller than the width of the groove, and the difference between the thickness of the fixing member and the width of the groove can be larger than zero. The fixation member is inserted and fixed in the fixture through the ceiling, and the fixation member is formed by: i) a first fixing part, which is fixed while being exposed through the exposure fixture, ii) a second fixing part connected to the first fixing part and forming an angle with the first fixing part, extending along a direction passing through the ceiling and partly inserted into the groove, iii) connected to the second fixing part, A third fixing part extending from the fixing part in a direction away from the light source seating member and iv) a fourth fixing part connected to the third fixing part and extending in a direction of gradually approaching the light source seating member from the third fixing part .

The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

Fig. 1 schematically shows a lighting fixture 100 according to a first embodiment of the present invention. The structure of the luminaire 100 of FIG. 1 is only for illustrating the present invention, and the present invention is not limited thereto. Therefore, the structure of the lamp 100 of FIG. 1 can be modified in other forms.

As shown in Fig. 1, the lamp 100 includes a light source casing member 10, a fixing member 20, and a light source seating member 30. As shown in Fig. In addition, the luminaire 100 may further include other components as needed. For example, the luminaire 100 further includes a diffuser plate 40. The diffusion plate 40 uniformly diffuses the light emitted from the light source toward the lower side of the lamp 100 while diffusing the light evenly. On the other hand, the diffusion plate 40 is fixed between the light source casing member 10 and the light source seat member 30. [ The fixing members 20 may be installed on both sides of the light source seating member 30 in a pair.

The light source casing member 10 is engaged with the light source seating member 30. The light source seating member 30 is made of a metal having excellent heat radiation effect, for example, aluminum, because the light source (not shown in the drawing, hereinafter the same) such as an LED is seated. On the other hand, Therefore, it can be manufactured with an inexpensive material such as resin. Therefore, the material cost of the lamp 100 can be greatly reduced.

A light source is seated in the light source seating member (30) and fixed. An outflow port 309 formed in the light source seating member 30 is formed to connect a wire (not shown) with an external power source and fix the light source with a screw (not shown) through the screw hole 311.

The light source casing member (10) includes a wall portion (101). The wall portion 101 protrudes toward the + z-axis direction. The wall portion 101 includes a first wall 1011 and a second wall 1013. The first wall 1011 and the second wall 1013 are interconnected. A groove 105 is formed in the second wall 1013. The groove 105 is located around the light source seating member 30. Due to the groove 105, the thickness of the second wall 1013 is larger than the thickness of the first wall 1011. The second wall 1013 is further projected in a direction away from the center A of the light source casing member 10 since the inner wall of the wall portion 101 is smoothly formed without the projection. A fixing protrusion 107 is formed on the inner surface of the wall portion 101 to fix the light source seating member 30 to the light source casing member 10. The light source seating member 30 is required to fix the diffuser plate 40 under the fixing protrusion 107 through the fixing protrusion 107 so that a groove 308 for passing the fixing protrusion 107 is formed at the edge thereof do. The grooves 308 can be formed at an angle of 120 degrees in total, as in the case of the fixing protrusions 107. [

On the other hand, an elastic member 209 is fixed to the opening 208 of the fixing member 20. The elastic member 209 is made of a metal wire, and the end of the elastic member 209 is wound on the opening 208 in a spring form and fixed to the fixing member 20 to have elasticity. Accordingly, when the elastic member 209 is folded and inserted into the ceiling in the + z-axis direction, the elasticity of the elastic member 209 causes the light source casing member 10 to be stretched in the direction of the xy plane, Can be fixed inside the ceiling.

The fixing member 20 is inserted and fixed in the groove 105, and then fixed through the ceiling. The fixing member 20 needs to be made of a material that can withstand the load of the luminaire 100 to stably fix the light source casing member 10 coupled with the light source seating member 30 to the ceiling. Therefore, it is preferable that the fixing member 20 is made of metal, for example, steel.

Meanwhile, since the light source casing member 10 is made of resin, the groove 105 can be easily formed through an injection process. Therefore, the fixing member 20 can be inserted into the groove 105 and fixed firmly. If the light source casing member 10 is made of metal, it is impossible to form the groove 105 in consideration of the manufacturing process and manufacturing cost. Therefore, the metal light source casing member can only be fixed on the side surface with the fixing member, so that the fixing member is not firmly attached to the light source casing member. In contrast, in the first embodiment of the present invention, since the light source casing member 10 made of resin is used, the groove 105 can be manufactured at low cost. Hereinafter, the installation state of the lamp 100 of FIG. 1 will be described in more detail with reference to FIG.

Fig. 2 schematically shows a cross-sectional structure of the lighting fixture 100 of Fig. The installation state of the lamp 100 of FIG. 2 is merely for illustrating the present invention, and the present invention is not limited thereto. Accordingly, the installation state of the lamp 100 can be variously modified.

2, the light source seating member 30 includes a light source seating portion 301, a side surface portion 303, and a supporting portion 305. As shown in Fig. In addition, the light source seating member 30 may further include other components as necessary.

A light source 50 is fixed to the light source seating portion 301. As the light source 50, an LED may be used. The light source 50 is fixed to the light source seating member 30 via a screw 62 and is connected to an external power source through the wiring 60. [ Therefore, the power required for driving the light source 50 can be supplied through the wiring 60.

The side portion 303 is connected to the light source seating portion 301. That is, the side surface portion 303 extends in the z-axis direction and cross-connects with the light source receiving portion 301 located on the xy plane. On the other hand, the support portion 305 is connected to the side portion 303 and is located above the light source casing member 10. Here, the wall portion 101 of the light source casing member 10 is positioned opposite to the side portion 303, and the support portion 305 is in contact with the inner side surface 1015 of the wall portion 101. The wall portion 101 surrounds the light source seating member 30 and is positioned. On the other hand, on the inner surface 1015 of the wall portion 101, the fixing protrusion 107 is inclined. The light source seating member 30 can be firmly fixed to the light source casing member 10 by using the fixing protrusion 107. [

On the other hand, as shown in Fig. 2, the lamp 100 is fixed through the ceiling (C). That is, when the lamp 100 is completely inserted into the ceiling C, the elastic member 209 is stretched over the ceiling C as shown in FIG. 2 by the elastic force of the elastic member 209. The lighting fixture 100 can be stably fixed to the ceiling C through this method.

Fig. 3 schematically shows the coupled state of the luminaire 100 of Fig. That is, FIG. 3 conceptually shows a state in which the light source seating member 30 (shown in FIG. 2, hereinafter the same) is coupled to the light source casing member 10. The state of engagement of the light source seating member 30 of FIG. 3 with the light source casing member 10 is merely for illustrating the present invention, and the present invention is not limited thereto. Therefore, the light source seating member 30 and the light source casing member 10 can be coupled to each other by other methods.

Fig. 3 partially shows an inner surface 1015 of the wall portion 101 of the light source casing member 10. Fig. The fixing protrusion 107 formed on the inner surface 101 is inclined. Here, the inclination angle of the fixing protrusion 107, that is, the inclination angle formed by the xy plane and the extending direction of the fixing protrusion 107 may be 10 to 40 degrees. When the inclination angle? Is too small, the light source seating member 30 enters the lower portion of the fixing protrusion 107 along the arrow direction and is not fixed by the fixing protrusion 107, which is stagnant. As a result, the light source casing member 10 and the light source seat member 30 are not coupled to each other. On the other hand, when the inclination angle? Is too large, it is difficult for the light source seating member 30 to enter the lower portion of the fixing projection 107 along the arrow direction. Therefore, the light source seating member 30 is not fixed to the light source casing member 10 well. Therefore, it is preferable to keep the inclination angle? In the above-described range.

On the other hand, screw grooves 109 are formed along the inner side surface 1015 below the fixing protrusions 107. [ A diffusion plate (40) is fixedly positioned immediately below the screw groove (109). The screw groove 109 includes a first screw groove 1091 and a second screw groove 1093. [ Since the first screw groove 1091 and the second screw groove 1093 are mutually connected to each other, the light source seat member 30 inserted into the first screw groove 1091 along the direction of the arrow indicates the first screw groove 1091 And then fixed by the fixing protrusion 107 while passing through the second screw groove 1093. [ As a result, the light source seating member 30 can be stably fixed to the light source casing member 10.

4A schematically shows the state before the fixing member 20 of the lamp 100 of FIG. 1 is assembled. 4B schematically shows the state after the fixing member 20 of the lamp 100 of FIG. 1 is assembled.

First, as shown in FIG. 4A, the fixing member 20 includes a first fixing portion 201 and a second fixing portion 203. The first fixing portion 201 and the second fixing portion 203 are connected to each other.

The second fixing portion 203 extends in the z-axis direction, that is, in the direction passing through the ceiling. The first fixing portion 201 is connected to one end of the second fixing portion 203. The first fixing part 201 is connected to the second fixing part 203 at an angle. The side wall of the wall portion 101 is formed with the exposure fixing portion 1051 communicating with the groove 105, so that the first fixing portion 201 can be fixed. 4A, the second fixing part 203 is inserted into the groove 105, and the fixing member 20 is fixed to the wall part 101 through the first fixing part 201 serving as a hook . On the other hand, since the elastic member 209 is coupled to the opening 208 formed in the second fixing portion 203, the light source casing member 10 (shown in Fig. 2, have.

The width w203 of the second fixing portion 203 may be larger than the width w201 of the first fixing portion 201 as shown in Fig. The width w203 of the second fixing part 203 must be large so that the width of the fixing member 20 is entirely enlarged so that the fixing part 20 can stably fix the wall part 101 and ultimately the light source casing member 10, Can be firmly fixed to the ceiling. The width w201 of the first fixing part 201 should be relatively small so that the first fixing part 201 can be easily inserted into the exposure fixing part 1051 to stably fix the fixing member 20 to the wall part 101 can do.

Here, the width w203 of the second fixing part 203 may be 20 mm to 50 mm. When the width w203 of the second fixing portion 203 is too large, it is not easy to bend the fixing member 20 and insert it into the groove 105. [ In addition, when the width w203 of the second fixing portion 203 is too small, the light source casing member 10 can not be stably supported by the fixing member 20, so that the lamp 100 City) may fall. Therefore, it is preferable to adjust the width w203 of the second fixing portion 203 to the above-mentioned range.

4B, when the second fixing portion 203 is inserted into the groove 105, the first fixing portion 201 is in a state of being in tight contact with the second fixing portion 203 by the groove 105 As shown in FIG. When the first fixing part 201 inserted into the groove 105 reaches the exposure fixing part 1051, it is fixed by the exposure fixing part 1051 while being expanded by the elastic force. That is, even if the fixing member 20 is pulled in the + z-axis direction because the upper end of the first fixing portion 201 is exposed to the outside of the exposure fixing portion 1051, the fixing member 20 Is not removed from the wall portion 101. Therefore, the fixing member 20 and the light source casing member 10 can be firmly coupled.

5 is a schematic exploded perspective view of a lamp 200 according to a second embodiment of the present invention. Since the structure of the lamp 200 according to the second embodiment of the present invention shown in Fig. 5 is similar to that of the lamp 100 according to the first embodiment of the present invention shown in Fig. 1, And detailed description thereof will be omitted.

5, the fixing member 22 is inserted and fixed in the groove 125 formed in the wall portion 121. As shown in Fig. Since the fixing member 22 includes a steel and is bent, it has the elasticity like the leaf spring. By disposing the three fixing members 22 at the same angle, that is, at 120 degrees, the support weight of the lamp 200 can be uniformly dispersed, and the lamp 200 can be efficiently fixed. Hereinafter, the fixing method of the lamp 200 of FIG. 5 will be described in more detail with reference to FIG.

Fig. 6 schematically shows a sectional structure of a state in which the lamp 200 of Fig. 5 is installed. Since the installation structure of the lamp 200 of FIG. 6 is similar to the installation structure of the lamp 100 of FIG. 2, the same reference numerals are used for the same parts and the detailed description thereof is omitted.

As shown in Fig. 6, the ceiling is provided with a luminaire fixing member 70 already passing through the ceiling. That is, when the incandescent bulb or the like is generally installed through the lamp fixture 70, the incandescent bulb can be removed and the LED or the like can be installed using the lamp 200.

The fixing member 22 is inserted to the inside of the lamp fixture 70 so as to install the lamp 200 in the lamp fixture 70. [ In this case, the light source fixing member 30 is inserted into the lamp fixture 70 and fixed. Since the fixing member 22 has elasticity, the lamp 200 can be fixed to the lamp fixture 70 using the elasticity of the fixing member 22. [

7), a second fixing portion 223, a third fixing portion 225, and a fourth fixing portion 227. The fixing portion 22 includes a first fixing portion 221 do. The first fixing part 221, the second fixing part 223, the third fixing part 225 and the fourth fixing part 227 are connected to each other in order.

The second fixing part 223 is angled with the first fixing part 221 and extends along the direction passing through the ceiling C. The second fixing portion 223 is partially inserted into the groove 125 formed in the wall portion 121 and fixed. The upper portion of the second fixing portion 223 is exposed to the outside. The third fixing part 225 extends from the second fixing part 223 in a direction away from the light source seating member 30. In other words, the third fixing part 225 extends from the second fixing part 223 in the direction away from the center of the lamp 200. On the other hand, the fourth fixing portion 227 extends from the third fixing portion 225 in a direction gradually closer to the light source seating member 30. [ That is, the fourth fixing portion 227 extends in the direction approaching the center of the lamp 200 and faces the third fixing portion 225 in the opposite direction, so that the fixing member 22 can be given an elastic force. The tangent line 226 between the third fixing part 225 and the fourth fixing part 227 is in contact with the lamp fixture 70 so that the lamp fixture 70 Can be fixed. Further, since the weight of the luminaire 200 is uniformly dispersed by using the three fixing members 22, the luminaire 200 can be stably fixed to the luminaire fixing member 70 using the elastic force of the fixing member 22 .

Fig. 7 schematically shows the state before the fixing member 22 of the lamp 200 of Fig. 5 is assembled. In Fig. 7, a fixing member 22 having a small width is used. It is possible to stably fix the lamp 200 to the lamp fixing member 70 by uniformly distributing the load of the lamp 200 using a plurality of fixing members 22 instead.

As shown in Fig. 7, the first fixing member 221 is connected to the second fixing member 223 at an angle. Since the fixing member 22 is made of metal having a bent shape and has an elastic force, the fixing member 22 is easily inserted into the ceiling in a reduced state, and after being inserted into the ceiling, the fixing member 22 is expanded again due to the elasticity thereof, 6) can be firmly fixed to the ceiling.

The second fixing portion 223 extends in the z-axis direction, that is, in the direction passing through the ceiling. The first fixing part 221 is connected to one end of the second fixing part 223. The side wall of the wall portion 121 is formed with the exposure fixing portion 1051 communicated with the groove 125 so that the first fixing portion 221 serving as a hook can be fixed. 7, the first fixing portion 201 is inserted into the groove 105, and the fixing member 10 is fixed to the wall portion 101 through the second fixing portion 203. Then, as shown in Fig.

The fourth fixing part 227 is inserted into the ceiling due to its elasticity because the third fixing part 225 is slightly inclined and inclined, and the fourth fixing part 227 is inserted into the ceiling of each part of the fixing member 22 The fixing member 10 can be easily inserted into the ceiling because the fixing member 10 is formed in a shape that is the first entry into the hole and is inclined in the opposite direction to the third fixing part 225. [

7, when the first fixing portion 221 is inserted into the groove 125, the first fixing portion 221 is brought into close contact with the second fixing portion 223 by the groove 125 As shown in Fig. When the first fixing part 221 inserted into the groove 125 reaches the exposure fixing part 1051, the first fixing part 221 is exposed and fixed through the exposure fixing part 1051 while being expanded by the elastic force. That is, even if the fixing member 22 is pulled in the + z-axis direction because the upper end of the first fixing portion 221 is exposed to the outside of the exposure fixing portion 1051, the fixing member 22 Is not removed from the wall portion 121. Therefore, the fixing member 22 can be firmly coupled to the wall portion 121.

Fig. 8 schematically shows another modification of the fixing member 22 of Fig. The fixing member 23 of Fig. 8 is the same as the fixing member 22 of Fig. 7 except that the first fixing portion 221 is not provided in the fixing member 22 of Fig.

The fixing member 23 has a simple structure not including the fixing means. Therefore, it is necessary to firmly fix the fixing member 23 to the groove 125 by adjusting the thickness of the fixing member 23. The thickness t23 of the fixing member 23 is formed to be smaller than the width t125 of the groove 125 corresponding thereto. Therefore, the fixing member 23 can be stably inserted into the groove 125. On the other hand, the difference between the thickness t23 of the fixing member 23 and the width t125 of the groove 125 may be greater than zero and less than or equal to 0.5 mm. The fixing member 23 may be detached from the groove 125 because the fixing member 23 is not fixed to the groove 125 and is loosened. Therefore, it is preferable to adjust the difference between the thickness t23 of the fixing member 23 and the width t125 of the groove 125 in the above-described range. On the other hand, since the groove 125 has an arcuate shape, the fixing member 23 inserted into the groove 125 in a bent state is in close contact with the inner surface of the groove 125 while being expanded. Therefore, the coupling force between the fixing member 23 and the wall portion 121 can be further increased by the elastic force of the fixing member 23. [

On the other hand, the thickness t23 of the fixing member 23 may be 1 mm to 2 mm. When the thickness t23 of the fixing member 23 is too small, the structural rigidity is low and the luminaire can not be stably fixed. In addition, when the thickness t23 of the fixing member 23 is too large, the material cost is increased, and it is not suitable for insertion into the groove 125, and it is difficult to have appropriate elasticity. Therefore, it is preferable to adjust the thickness t23 of the fixing member 23 to the above-mentioned range. The thickness of the fixing member 20 (shown in FIG. 4A) included in the lamp 100 (shown in FIG. 1) of the first embodiment of the present invention can also be adjusted to the above-described range.

Hereinafter, the present invention will be described in more detail with reference to experimental examples. These experimental examples are only for illustrating the present invention and the present invention is not limited thereto.

As shown in Fig. 9, first, a light source casing member having a diameter of 170 mm was manufactured through an injection process using polycarbonate. In this case, the height of the wall portion included in the light source casing member was 15 mm. Then, an aluminum plate was molded to manufacture a light source seating member. The diameter of the light source seating member was about 130 mm. Further, a fixing member made of steel was produced. The thickness of the fixing member was 1 mm, and the width of the second fixing portion included in the fixing member was 8 mm. The light source seating member, the light source casing member, and the fixing member were coupled to each other to manufacture a luminaire. The mounting position of the luminaire was checked by adjusting the width of the first fixing part of the fixing member while installing the luminaire on the ceiling. As the width of the first fixing part is adjusted, the groove of the wall part into which the first fixing part is inserted is also adjusted accordingly. The detailed experimental conditions are easily understood by those skilled in the art, and detailed description thereof will be omitted.

Experiment result

Table 1 shows the experimental results of the luminaire according to Experimental Examples 1 to 12 described above.

Experimental Example  1

In Experimental Example 1, the fixing member having the same width as that of the first fixing portion and the same width as the second fixing portion was used. As a result, the fixing member was inserted well in the groove, but was loose. Therefore, when the luminaire is installed on the ceiling, there is a problem that the fixing member does not hold the light source casing member well and falls down. Also, the load of the fixing member was poor.

Experimental result of Experimental Example 2

In Experimental Example 2, the fixing member was well inserted into the groove. However, when the luminaire is installed on the ceiling, there is a problem that the fixing member can not hold the light source casing member well and falls down. Therefore, the load of the fixing member was poor.

Experimental results of Experimental Example 3

In Experimental Example 3, the fixing member was inserted into the groove well. However, when the luminaire is installed on the ceiling, there is a problem that the fixing member can not hold the light source casing member well and falls down. Therefore, the load of the fixing member was poor.

Experimental results of Experimental Example 4

In Experimental Example 4, the fixing member was inserted well in the groove. Further, when the luminaire is installed on the ceiling, the fixing member holds the light source casing member well. Therefore, the fixture can securely fix the luminaire to the ceiling.

Experimental results of Experimental Example 5

In Experimental Example 5, the fixing member was inserted into the groove well. Further, when the luminaire is installed on the ceiling, the fixing member holds the light source casing member well. Therefore, the fixture can securely fix the luminaire to the ceiling.

Experimental results of Experimental Example 6

In Experimental Example 6, the fixing member was inserted well into the groove. Further, when the luminaire is installed on the ceiling, the fixing member holds the light source casing member well. Therefore, the fixture can securely fix the luminaire to the ceiling.

Experimental results of Experimental Example 7

In Experimental Example 7, the fixing member was inserted into the groove well. Further, when the luminaire is installed on the ceiling, the fixing member holds the light source casing member well. Therefore, the fixture can securely fix the luminaire to the ceiling.

Experimental results of Experimental Example 8

In Experimental Example 8, the fixing member was well inserted into the groove. Further, when the luminaire is installed on the ceiling, the fixing member holds the light source casing member well. Therefore, the fixture can securely fix the luminaire to the ceiling.

Experimental results of Experimental Example 9

In Experimental Example 9, the fixing member was inserted well in the groove. Further, when the luminaire is installed on the ceiling, the fixing member holds the light source casing member well. Therefore, the fixture can securely fix the luminaire to the ceiling.

The experimental results of Experimental Example 10

In Experimental Example 10, the fixing member was inserted well in the groove. Further, when the luminaire is installed on the ceiling, the fixing member holds the light source casing member well. Therefore, the fixture can securely fix the luminaire to the ceiling.

Experimental results of Experimental Example 11

In Experimental Example 11, the width of the fixing member was greatly increased, and the strength thereof was increased, so that it became more difficult to insert the member into the groove by bending the fixing member. On the other hand, when the fixture is used to mount the luminaire on a ceiling, the fixture can hold the luminaire casing member securely, and the luminaire can be stably fixed to the ceiling.

Experimental results of Experimental Example 12

In Experimental Example 12, the width of the fixing member was greatly increased, and the strength of the fixing member was increased, making it difficult to insert the fixing member into the groove by bending the fixing member. On the other hand, when the fixture is used to mount the luminaire on a ceiling, the fixture can hold the luminaire casing member securely, and the luminaire can be stably fixed to the ceiling.

As can be seen from the above Experimental Examples 1 to 12, the best results were obtained in Experimental Examples 4 to 10. That is, the luminaire manufactured according to Experimental Examples 4 to 10 was easy to insert the fixing member into the groove and was able to fix the luminaire securely to the ceiling. Therefore, the design conditions of the luminaire can be optimized by adjusting the width of the first fixing part according to Experiment 4 through Experiment 10. More preferably, adjusting the width of the first fixing part in accordance with Experimental Examples 6 to 8 can further optimize the design conditions of the luminaire.
