Description

  The present invention relates to an LED lighting device mounting fixture and an LED lighting device mounting method for preventing LED damage due to twisting of a lighting device using a semiconductor light emitting element, so-called LED.

  2. Description of the Related Art In recent years, lighting devices using LEDs have been paid attention to characteristics such as good durability, low power consumption, and broadening of a light emission frequency band, and their use has been expanded in a wide range of homes, automobiles, stores, factories, and the like. For example, in a semiconductor manufacturing factory, an LED lighting device is used as a lighting fixture having a light emission frequency that does not interfere with resist coating in a photoresist coating process on a semiconductor wafer.

  FIG. 4 is an exploded view for explaining a configuration in which the LED lighting device 11, which is generally used as a base light, is used by being suspended and fixed to a raceway 12. The LED lighting device 11 shown in the figure has a horizontally long mounting board 15 having a long side 13 of about 1100 mm and a short side 14 of about 250 mm. The raceway 12 is open at the bottom and has an edge that is bent inward at the opening. The opening width of the raceway 12 is about 60 mm. In the vicinity of both ends of the mounting board 15 of the LED lighting device 11, a pair of bolt holes 17 a and 17 b are provided on the extension line of the center of the short side 14. Further, a cable for passing a power cable or the like through the center of the mounting board 15. A hole 18 is formed.

  LED light emitting portions 19 a and 19 b are provided along the long sides 13 and 13 of the mounting substrate 15 that face each other. In the LED light emitting portions 19a and 19b, a large number of semiconductor light emitting elements are arranged and arranged inside although not shown. Further, a triangular reflector 20 is provided between the LED light emitting units 19a and 19b, and the light emitted from the LED light emitting units 19a and 19b is efficiently reflected downward.

  The LED lighting device 11 having such a configuration includes bolt holes 17a and 17b provided on the mounting board 15 by a pair of suspension bolts 21a and 21b, mounting brackets 22a and 22b, and nuts 23a and 23b. It is suspended and installed on the raceway 12 using.

  By the way, the LED light emitting units 19a and 19b provided in the LED lighting device 11 are usually composed of a large number of LED elements arranged on a semiconductor substrate, and each LED element is formed of a fine bonding wire or the like on the semiconductor substrate. It is connected to various places, and the LED element itself has a very fine and precise configuration, and is easily damaged by a small external factor that impairs the LED light emitting function.

  In a clean room where the presence of fine dust is extremely hated in the semiconductor manufacturing process, clean air is blown down from the ceiling, exhausted from the floor, and clean air filtered through a filter is blown down from the ceiling again. Many circulatory systems are formed. In such a clean room environment, when the LED lighting device 11 is suspended and installed on the raceway 12 shown in FIG. 4, the influence on the LED lighting device 11 will be described with reference to FIGS. 5 and 6.

  The LED lighting apparatus shown in FIGS. 5A and 6B is common in the configuration described in FIG. 4, but the width of the raceway 12 in FIG. 5A, that is, the opening width is less than 60 mm. Thus, the width of the raceway 12 in FIG. 6A is 60 mm or more. FIGS. 5B and 6B are diagrams schematically showing the phenomenon of FIGS. 5A and 6A in an easy-to-understand manner. 5 and 6 are views of the configuration of FIG. 4 as viewed from the side, that is, from the direction in which the cross section of the raceway 12 is the front. When clean air blows down from above in a clean room, the clean air flow blown down on the upper surface of the LED lighting device 11, that is, on both sides of the raceway 12, hits the airflow from the upper surface via the side edges. Head down.

  At this time, as shown by the upper and lower thick arrows 24a and 24b in the drawing, the LED illumination device 11 is shaken with the raceway 12 as a fulcrum. And the airflow which blows down and hits the LED lighting apparatus 11 does not hit all the places on the upper surface of the LED lighting apparatus 11 uniformly. The airflow which hits the upper surface of the LED lighting device 11 also becomes irregular depending on the installation location of the LED lighting device 11, the air discharge location where the air blows down, and various devices installed in the clean room.

  As a result, the influence of the air flow on the LED lighting device 11 is not simply applied with a uniform force upside down as shown in FIG. 5 and FIG. As a result, an external force is applied to the LED illumination device 11. As a result, as described above, when an external force is applied to the LED lighting device 11, an external force is applied to the fine-structured LED element formed inside the device, resulting in damage to the LED element structure. Will be given. The width of the raceway 12 in FIG. 5 is less than 60 mm, and the width of the raceway 12 in FIG. 6 is 60 mm or more. Therefore, the example of FIG. Will be. Moreover, as a factor causing the LED lighting device 11 to sway and twist, not only clean air that blows down but also vibrations caused by other factors may be the cause.

  In the configuration of FIG. 4, the upper portion of the mounting substrate 15 of the LED lighting device 11 is not a uniform and flat plane, and various members for mounting the LED light emitting portions 19a, 19b and the like are not shown in the figure. And other small devices are arranged, so that the surface is uneven. For this reason, dust is likely to collect in the narrow portions of the unevenness, and when such water leaks from the upper part or other liquids, such water or the like stays in the narrow uneven portions. It's easy to do.

  Shake and twist of the LED lighting device suspended on the raceway reduces or eliminates damage to the LED element structure in the LED lighting device, and makes it difficult to collect dust, water, etc. on the LED lighting device. It is possible to quickly remove the generated dust, and to provide an LED lighting device mounting apparatus and an LED lighting device mounting method that do not cause direct shaking or twist in the LED lighting device itself, and that dust and the like are less likely to stay. With the goal.

  An LED lighting device mounting apparatus according to claim 1 of the present invention is mounted between a raceway and an LED lighting device suspended from the raceway, and has a flat upper surface that is mounted in close contact with the upper portion of the LED lighting device. It is a base plate.

  In the LED lighting device mounting method according to claim 5 of the present invention, a bolt hole and a cable hole are formed in the LED lighting device which is a rectangular parallelepiped having a short side and a long side, and the bolt hole of the LED lighting device A mounting base plate having a bolt hole and a cable hole at a position corresponding to the cable hole, the mounting base plate being disposed in close contact with the upper part of the LED lighting device, and a race disposed on the upper part of the mounting base plate The mounting base plate and the LED lighting device are suspended and fixed to the raceway in this order by screwing the bolt with a nut through the mounting base plate and the bolt hole of the LED lighting device. It is characterized by doing.

  Reduced damage to the LED element structure in the LED lighting device by mounting the mounting base plate between the raceway and the LED lighting device so that the LED lighting device suspended on the raceway is not directly shaken or twisted. In addition, dust and water are less likely to stay on the LED lighting device, and accumulated dust can be quickly removed.

The exploded mounting view for demonstrating one Example of this invention. The perspective view of the principal part of FIG. The figure which looked at the state equipped with one example of the present invention from the other direction. The figure for showing the attachment structure of the conventional LED lighting apparatus. The figure for demonstrating the influence of the external force applied to the LED lighting apparatus shown in FIG. The figure for demonstrating the influence of the external force applied to the other example of the LED lighting apparatus shown in FIG.

  Hereinafter, an embodiment according to the present invention will be described with reference to FIGS. 1 to 3. FIG. 1 is an exploded view of a configuration in which the mounting base plate 25 according to the present invention is mounted between the raceway 12 and the LED lighting device 11 shown in FIG. In FIG. 1, portions common to FIG. 4 are denoted by the same reference numerals, and detailed description thereof is omitted. 2 is a view showing only the mounting base plate 25 of FIG. 1, and FIG. 3 is a view of the assembled structure of FIG.

  The mounting base plate 25 is made of stainless steel. Bolt holes 17a and 17b are formed in the mounting base plate 25 at positions corresponding to the bolt holes of the LED lighting device 11, as shown in FIG. Similarly, a cable hole 18 is formed at a position corresponding to the cable hole of the LED lighting device 11. As a result. As shown in FIG. 1, the mounting base plate 25 is fixed between the raceway 12 and the LED lighting device 11 by suspension bolts 21a and 21b and nuts 23a and 23b.

  Thus, by using the mounting base plate 25, the mounting brackets 22a and 22b shown in FIG. 4 can be omitted.

  The long side 26 of the mounting base plate 25, that is, the length of the side 26 parallel to the raceway 12 is the same as the long side 13 of the LED lighting device. Further, the short side 27 of the mounting base plate 25, that is, the length of the orthogonal side 27 of the raceway 12 is longer than the short side 14 of the LED lighting device 11 as shown in FIG. In addition, although the length of the long side 26 of the attachment base board 25 was made into the same length as the long side 13 of the LED lighting apparatus 11 in the said example, you may make it longer than the long side of the LED lighting apparatus 11.

  The upper surface of the mounting base plate 25 is a flat surface without unevenness. Further, an edge 28 bent downward is formed on the long side 26 of the mounting base plate 25. The length of the edge 28 may be a width that does not hinder the illumination effect of the LED lighting device 11. The mounting base plate 25 is made of stainless steel, but may be made of other materials such as plastic as long as it is not easily bent or twisted.

  By attaching the mounting base plate 25 to the raceway 12 in close contact with the upper surface of the LED lighting device 11, the air flow caused by the down blow of clean air in a clean room or the like does not directly hit the LED lighting device 11. As a result, the shaking and twisting of the LED lighting device 11 due to the air flow caused by the down blow were almost not recognized. This is because the mounting base plate 25 receives the down-blow air flow, so that the mounting base plate 25 receives the cause of the shaking and twisting, and the LED lighting device 11 is not directly affected. It is because.

  Further, since the upper surface of the mounting base plate 25 is flat, there are no narrow portions such as unevenness as in the upper part of the conventional LED lighting device 11, and there is no cause for dust and water to stay. Even if dust, water, or the like may temporarily fall on the upper surface of the mounting base plate 25, these dust, water, etc. are easily removed by the air flow of down blow. Further, by providing the edge 28 on the long side 26 of the mounting base plate 25, when dust, water, or the like dropped on the upper portion of the mounting base plate 25 is removed downward, the dust, water, or the like is emitted from the LED lighting device. It was possible to prevent the camera from falling toward the head 11.

  The length of the short side 27 may be made substantially the same as the length of the short side 14 of the LED lighting device 11 by making the material and dimensions of the mounting base plate 25 more resistant to shaking and twisting. However, in this case, when dust, water, or the like from the upper part of the mounting base plate 25 falls downward, this influence may be exerted on the LED lighting device 11. In an environment where there is no fear of this, it is possible to make the short side 27 of the mounting base plate 25 substantially the same as the short side of the LED lighting device 11.

  However, as a result of making the width of the short side 27 of the mounting base plate 25 longer than the short side 14 of the LED lighting device 11, the influence of the shaking and twisting factors of the mounting base plate 25 is not further exerted on the LED lighting device 11. It was possible. In addition, as a result of making the short side 27 of the mounting base plate 25 longer than the short side 14 of the LED lighting device 11, when dust or water dropped on the top of the mounting base plate 25 is excluded downward, It is possible to reduce the adverse effect on the LED lighting device 11 due to water or the like. Therefore, what is necessary is just to determine according to the surrounding environment which installs the LED lighting apparatus 11 in determining the length of the short side of the attachment base board 25.
