Description

  The present invention mainly relates to an improvement of a straight tube type LED lighting apparatus mainly installed on a ceiling surface of a relatively large facility such as a commercial facility such as an office or a store, and particularly, easy installation and assembly work. It is about safe and secure.

  In recent years, LED lamps with built-in power supplies that use LED elements with excellent power savings as light sources have become widespread due to increasing environmental awareness. In particular, recently, a straight tube type LED lighting device having a long LED module has been developed and introduced into the market as an alternative product of a relatively long straight tube fluorescent lamp.

  Such a straight tube type LED lighting device generally includes a main body attached to a surface to be attached such as a ceiling surface and a light source module such as an LED module attached to the main body, and either the main body or the light source module. In addition, a power supply box for supplying electricity to the lighting device is arranged (see, for example, Patent Document 1). In this case, as shown in FIGS. 4 and 5, the power supply box 24 is arranged so as to be biased to either the left or right from the central portion C (see FIG. 4) in the width direction of the main body 12 (or the light source module 14). It was. This is because, as shown in FIG. 4, in the lighting device 10, there is provided a space for wiring a flat vinyl sheathed cable (VVF cable) 1 or the like that is connected to a power source or the like and supplies power to the lighting device 10. . Therefore, as shown in FIGS. 4 and 5, the central portion C2 (see FIG. 4) in the width direction of the power supply box 24 does not coincide with the central portion C (see FIG. 4) in the width direction of the lighting device 10, and The center of gravity of the box 24 was deviated from the center of gravity of the lighting device 10.

  However, when the power supply box is arranged so as to be biased to the left or right in the lighting device, the power supply box is relatively heavy, and the center of gravity becomes unbalanced. In this case, since the lighting device is mounted on the stepladder while supporting the lighting device from below by an operator, if the center of gravity is thus unbalanced, the mounted surface such as the ceiling surface, etc. When attaching to the projector, it is necessary to work while maintaining a balance. This is troublesome, and if the lighting device loses balance and tilts, it may fall off at once.

  In this case, on the other hand, if the power supply box is arranged at the center of the lighting device, a wiring space such as a VVF cable cannot be secured, and if an attempt is made to secure the space, a large space is set on both sides of the power supply box. The necessity arises and the problem that the main body and the light source module increase in size arises.

Therefore, there is an advantage that it is easy for the operator to balance in the mounting operation, and the main body or the light source module having the power supply box can be easily and safely mounted.

  In addition, according to the present invention, as described above, the power supply box has a storage groove that can store the cable on the outer surface, so that the cable such as the VVF cable can be stored without being bulky in the height direction. At the same time, the storage groove increases the surface area of the power supply box and has the benefit of increasing the heat dissipation effect.

  In this case, according to the present invention, as described above, since the storage groove is formed on the center of gravity of the power supply box, even if the VVF cable is arranged in the storage groove, the balance of the center of gravity is affected. In addition, there is an advantage that the high handling property can be maintained with a good balance.

  Further, in this case, according to the present invention, as described above, the various electronic components housed in the power supply box are located at positions away from the center line extending in the longitudinal direction of the power supply box so as to avoid the housing groove. Because it is mounted, even if it is a relatively tall electronic component, a compact lighting device that is not bulky in the height direction while storing the cable in the storage groove (while placing the cable on the power supply box) There is a real benefit that can be.

  FIG. 1 shows a lighting device 10 according to the present invention. Embodiments of the present invention will be described in detail with reference to the drawings. For example, many lighting devices 10 are provided on a ceiling surface of a commercial facility such as a business office or a store. Installed and used to illuminate a relatively large space. As shown in FIG. 1, the illuminating device 10 is a long straight tube illuminating device 10, and includes a main body 12 attached to a surface to be attached such as a ceiling surface, and a light source module attached to the main body 12. 14.

(1. Body)
As shown in FIG. 1, the main body 12 includes a recessed groove portion 12A provided in the center, and tapered portions 12B formed so as to extend from both end surfaces in the longitudinal direction of the groove portion 12A. It is directly attached to a mounting surface such as a ceiling surface by an anchor bolt (not shown) through a mounting hole (not shown) formed on the top surface. As shown in FIG. 1, the groove 12A has a top surface 12a and inner wall surfaces 12b formed so as to rise from both ends of the top surface 12a. In the illustrated embodiment, the power supply box 24 and the like mounted on the LED module 2 are also accommodated. The main body 12 can be formed by, for example, pressing a metal material such as a color steel plate that is relatively light and has high heat dissipation.

(2. Light source module)
On the other hand, the light source module 14 is formed in a long shape corresponding to the groove 12A of the main body 12, as shown in FIGS. The light source module 14 is not particularly limited, and a straight tube fluorescent lamp unit or the like can be used, but an LED module is desirable. In the case of an LED module, the light source module 14 includes a heat sink 16, an LED board 18 attached to the heat sink 16, and a plurality of LEDs mounted on the LED board 18, as shown in FIGS. 1 and 2. LED element 20, translucent cover 22 provided to cover LED substrate 18 and LED element 20, and power supply box 24 for supplying electricity to light source module 14.

(2-1 Heat sink)
The heat radiating plate 16 has a function of radiating heat generated from the LED substrate 18 and has a substantially U-shaped cross section including a bottom surface portion 16A and both wall surface portions 16B as shown in FIG. Further, as shown particularly in FIG. 1, the heat radiating plate 16 has a folded portion 16C formed by folding the upper ends of both wall surface portions 16B toward the bottom surface portion 16A. The folded portion 16C improves the strength of the heat radiating plate 16. In particular, even when a relatively heavy power supply box 24 is mounted, it is possible to prevent the light source module 14 from being deformed such as bending. In addition, this heat sink 16 can be integrally molded by extruding aluminum.

(2-2-2 LED substrate and LED element)
The LED substrate 18 is made of a glass composite substrate (CEM-3), and the LED element 18 is mounted on one surface as shown in FIG. The LED substrate 18 is preferably attached to the heat radiating plate 16 through an insulating sheet (not shown) in order to increase the heat radiation efficiency for radiating heat associated with light emission. However, the insulating sheet only needs to be installed as necessary, and does not necessarily have to be directed. In addition, as LED element 20, well-known various LED can be used. In the illustrated embodiment, a high-luminance LED element that emits white light for illumination is used.

  The shape of the LED board 18 and the arrangement of the LED elements 20 arranged in the light source module 14 are not particularly limited. For example, the LED board 18 is mounted near both ends (longitudinal start and end) of the LED board 18. It is desirable that the density of the LED elements 20 is higher than the density of the LED elements 20 arranged near the central portion of the LED substrate 18 and concentrated. Thereby, it is possible to suppress a decrease in luminous intensity at both ends of the lighting device 10, and in particular, even when a plurality of lighting devices 10 are connected and continuously arranged on the ceiling surface, a connecting portion between the lighting devices 10. It is possible to suppress the decrease in the brightness of the light source, maintain the continuity of light, and ensure linear light emission.

  In the illustrated embodiment, the light source module 14 and thus the LED board 18 loaded therein is formed in a flat plate shape. However, the light source module 18 is inverted V-shaped in consideration of light diffusion efficiency. It is also possible to form a mold and arrange the LED substrate 18 in an inverted V shape on each inclined surface, or to arrange the flexible LED substrate 18 by bending it into an inverted V shape.

(2-3 Power supply box)
Further, as shown in FIGS. 1 and 2, the power supply box 24 is provided on the back side of the LED substrate 18 in the light source module 14, that is, the surface on which the LED elements 20 are mounted (the floor surface side when installed on the ceiling surface). ) Is installed on the opposite side. Specifically, as shown in FIGS. 1 and 2, the power supply box 24 is mounted on the surface of the heat radiating plate 16 opposite to the surface on which the LED substrate 18 is mounted. This is for accommodating the power supply box 24 in the groove 12 </ b> A of the main body 12 when the light source module 14 is mounted on the main body 12.

  In this case, in the present invention, as shown in FIGS. 1 and 2, the power supply box 24 has the center of gravity of the power supply box 24 located at the central portion C (see FIGS. 1 and 2) in the width direction of the lighting device 10. Are arranged and installed. Specifically, the power supply box 24 is arranged at a position where the center of gravity coincides with the center of gravity of the lighting device 10 as shown in FIG. In this case, normally, as shown in FIG. 2, in the light source module 14, it is sufficient to install the power supply box 24 at a position at an equal distance from the left and right wall surfaces 16 </ b> B of the heat radiating plate 16.

  Thereby, the power supply box 24 can be arrange | positioned in the center part C (refer FIG.1 and FIG.2) in the width direction of the illuminating device 10, and the center of gravity of the power supply box 24 in the width direction of the illuminating device 10 (FIG. 1 and FIG. 2) are placed and installed so that the center of gravity gathers in the center and balance is achieved, so that it is easy for the operator to balance during installation work, and the power box is simple and safe A light source module 14 having 24 can be attached.

Further, in the present invention, as shown in FIG. 1 in particular, the power supply box 24 has a storage groove 26 that can store a cable 1 such as a flat vinyl sheathed cable (VVF cable) on the outer surface. Yes. As shown in FIG. 1, the storage groove 26 has a tapered wall surface that increases in width toward the upper side so that the cable 1 can be easily stored. The cable 1 is stored in the storage groove 26. Thus, the power supply box 24 can secure a space for storing a cable such as a VVF cable without being bulky in the height direction, and the power supply box 24 is disposed at the center in the width direction of the light source module 14. In addition, a wiring space can be secured without increasing the size. At the same time, the storage groove 26 having the concave shape increases the surface area of the power supply box 24 as shown in FIG. In this case, the depth of the receiving groove 26, the height of the cable 1 to be accommodated (or diameter) in response to and the number can be suitably set, anyway, as shown in FIG. 1, housing It is desirable that the cable 1 has a depth that does not protrude significantly from the upper surface of the power supply box.

  In addition, the storage groove 26 is formed on the center of gravity of the power supply box 24 as shown in FIG. Specifically, as shown in FIG. 1, the storage groove 26 is formed around a central portion in the width direction of the power supply box 24. For this reason, even if a cable 1 such as a VVF cable is arranged in the storage groove 26, as shown in FIG. 1, the handling property is maintained with a good balance without affecting the balance of the center of gravity. Can do.

  Further, as shown in FIG. 1, the power supply box 24 serves as a cover for various electronic components 28 such as a lighting circuit housed therein. In this case, these various electronic components 28 are connected to the power supply box 24. It is mounted at a position off the center line extending in the longitudinal direction. Specifically, as shown in FIG. 1, at least the particularly tall electronic component 28 is disposed at both ends in the power supply box 24 so as to avoid the central storage groove 26. Accordingly, the cable 1 can be stored in the storage groove 26 while storing the relatively tall electronic component 28 (the cable 1 can be disposed on the power supply box 24), and the height can be increased. It can be set as the compact illuminating device 10 without being bulky.

  Of course, the electronic component 28 having a height that can be stored below the storage groove 26 can be installed in the center of the power supply box 24 in the width direction, that is, below the storage groove 26. In this case, as shown in FIG. 1, the various electronic components 28 to be housed in the power supply box 24 are evenly arranged on the left and right sides of the center in the width direction, so that the center of gravity of the power supply box 24 itself can be set in the width direction. It can be set at the center. However, the arrangement and weight of the electronic component 28 do not necessarily have to be exactly equal to the left and right except for an extreme arrangement such as, for example, placing the electronic component 28 biased to only one end in the power supply box 24. .

  In the illustrated embodiment, the power supply box can be easily maintained and replaced by simply removing the light source module 14 from the main body 12 without removing the main body 12 from the mounting surface. 24 is installed on the light source module 14 side, but is not necessarily limited to this form, and can be installed on the main body 12 side as long as the center of gravity is taken into consideration, unlike the illustrated embodiment.

(2.-4 Translucent cover)
Further, as shown in FIG. 1, the translucent cover 22 is formed on the tapered portion 12 </ b> B of the main body 12 on a gentle tapered surface following the drawing, and exhibits excellent design as the lighting device 10. As shown in FIG. 1, the translucent cover 22 is fitted with the bent portion 16 </ b> B of the heat radiating plate 16 in order to slide and assemble from the end portion in the longitudinal direction of the light source module 14. There is no fear.

(2.-5 Reflection means)
Although not shown, the light source module 14 is desirably provided with a reflecting means that is provided along the LED substrate 18 and reflects light emitted from the LED element 20 in a direction to be irradiated. By this reflecting means, it is possible to irradiate light concentrated on the front side where light irradiation is required (floor surface side when installed on the ceiling surface), and to improve the irradiation efficiency of the entire illumination device 10. .

  Specifically, a reflecting sheet can be used as the reflecting means. This reflection sheet is continuously provided on both sides of the LED element 20 on the mounting surface side (the floor surface side when attached to the ceiling surface) of the LED element 20 in the LED substrate 18. It is provided along the LED substrate 18 by being fixed together with the LED substrate 18 by a plastic rivet for fixing to the same. Specifically, a resin sheet or the like formed from foamed polyethylene terephthalate can be used as the reflection sheet. In addition, this reflection sheet can also be installed in LED board 18 with the tape and adhesive agent which are not shown in figure. However, the reflection means is not limited to this reflection sheet, and, for example, a highly reflective resin applied to the mounting surface of the LED substrate 18 can also be used.

(3. Mounting the LED module to the main unit)
The mounting of the LED module 14 to the main body 12 is not particularly limited, and any appropriate means can be used. However, a spring receiver (not shown) provided on the main body 12 and the spring provided on the light source module 14 are provided. A spring 30 shown in FIG. 2 that engages the receiver can be used. However, it is also possible to install a spring on the main body 12 side and a spring receiver on the light source module 14 side.

(4. Other embodiments)
In the embodiment shown in FIG. 1, the storage groove 26 is provided on the top surface of the power supply box 24. However, the location of the cable is not particularly limited. For example, as shown in FIG. It is also possible to form a recessed cable storage portion 32 on the inner wall surface 12 b of the cable and fix the cable 1 in the cable storage portion 32 for wiring. Even if the power supply box 24 is arranged in the center, the cable storage portion 32 can secure the wiring space of the cable 1.

  The present invention can be widely applied to, for example, a straight-tube illumination device 10 and other illumination devices that are mainly installed on a ceiling surface of a relatively large facility such as a commercial facility such as an office or a store.
