Further, as the characteristics of the LED 15a, it is excellent in power saving and has a long life as compared with a lighting device using a conventionally known fluorescent lamp.

  The lighting device 1 will be described in detail with reference to FIGS. First, as shown in FIG. 3, since the lighting device body 2 is formed by extrusion molding of aluminum, the lighting device main body 2 is extended in the left and right longitudinal directions so that one of the sections opens in a U shape in a cross-sectional downward direction. At the same time, the dovetail groove 3a is continuously recessed in the longitudinal direction at the front and rear intermediate positions of the upper central plate-like portion 3. As described above, the lighting device main body 2 is formed by extrusion molding of aluminum, so that it is easy to form the dovetail groove 3 a over the entire length in the longitudinal direction of the central plate-like portion 3. And since each site | part of the illuminating device main body 2 is also integrally formed, weight reduction is achieved without becoming a complicated structure. A reinforcing member 13 made of a rigid plate member extending in the longitudinal direction can be inserted and attached to an intermediate position of the dovetail groove 3a from above, and other than the attachment position of the reinforcing member 13 to the dovetail groove 3a. The aforementioned mounting members 20, 20 can be attached to the left and right ends of the dovetail groove 3a.

  The lighting device main body 2 will be described in detail. As shown in FIG. 5, grooves 3c and 3c are formed along the longitudinal direction on the front and back of the bottom portion of the dovetail groove 3a formed in a flat shape, and the dovetail groove 3a. Before and after the opening, protrusions 3d and 3d are formed along the longitudinal direction. The dovetail groove bottom width D between the grooves 3c-3c is formed to be longer than the dovetail groove opening width C between the protrusions 3d-3d.

  In attaching the reinforcing material 13, double-sided tape or adhesive having adhesive strength is applied in advance to the lower surface of the reinforcing material 13, and the short side width E before and after the reinforcing material 13 is larger than the groove opening width C. Since it is short, contact between the two can be avoided. Therefore, the reinforcing material 13 can be easily attached only by placing it on the groove 3a with the coating surface of the reinforcing material 13 facing down.

  A flat lower surface 3b is formed on the back surface of the central plate-like portion 3, and serves as a mounting surface for a wiring board 14 to be described later. Upper and lower edges 4c and 4c projecting in the lateral direction are formed on the front and rear sides of the central plate-shaped portion 3, and side portions 4 and 4 extend downward from the upper edge 4c and 4c. And the lower end edges 4b and 4b which protrude in a transversal direction from the free end part of the side parts 4 and 4 are formed.

On the inner side surfaces 6 and 6 inside the lighting device main body 2, upper grooves 6a and 6a are formed in the upper part in the longitudinal direction, and lower grooves 6b and 6b are formed in the lower part in the longitudinal direction.

  As shown in FIG. 3, an outer peripheral edge 12b is projected on the inner surface side of the side end members 12 and 12 located on the left and right end surfaces 7 and 7 side of the lighting device body 2, and a recessed surface 12d is formed in the center. Has been. A pair of fitting pieces 12a project from the two positions before and after the upper end of the recessed surface 12d toward the illuminating device main body 2 and can be fitted into the pair of upper grooves 6a of the illuminating device main body 2, respectively.

  The wiring board 14 is formed of a rectangular thin plate extending in the left-right direction, and the illumination unit 15 including the LED 15a described above is provided in a straight line at a predetermined interval along the longitudinal direction at the front-rear intermediate position. The LED 15a is formed by covering a light source body with a transparent synthetic resin material. On the right side of the wiring board 14, an operation unit 16 having a button 16a that can be pressed upward is provided, and on the left side, a control unit 17 that controls the plurality of illumination units 15 is provided.

  These members (15, 16, 17) are connected by a cord 18 and an internal connection wiring 19. The control unit 17 has a converter function for converting AC power from the cord 18 into DC, controls the illuminance and color of the LED 15a, and controls the LED 15a based on the ON / OFF signal from the operation unit 16 by operating the button 16a. It has functions.

  Next, the translucent plate 10 will be described. The translucent plate 10 of this embodiment is molded using a plastic resin material and is formed of a rectangular thin plate extending in the left-right direction. Stepped end portions 10a and 10a are formed on the front and rear edges of the light transmitting plate 10, and an intermediate portion is a light transmitting portion 10b that can transmit the light of the LED 15a. A button hole 10c penetrating vertically is formed on the right side of the translucent portion 10b, and a part of the lower portion of the button 16a can be protruded downward when the translucent plate 10 is attached to the illuminating device body 2 described later. .

  Therefore, the pair of attachment members 20 and 20 will be described with reference to FIGS. The mounting members 20 and 20 are formed by bending a sheet metal, and a stepped portion 24 bent in a crank shape that is displaced by approximately 90 degrees in an L shape when viewed from the side is formed at a substantially intermediate position of the mounting members 20 and 20. A flat mounting portion 21 is formed above the step portion 24. Note that the height of the stepped portion 24 is larger than the vertical height (depth) of the groove portion 3a.

  The attachment portion 21 is formed with a screw insertion hole 21a penetrating vertically. A flat fitting portion 22 is formed below the step portion 24 so as to be a plane parallel to the mounting portion 21. The fitting part 22 has a substantially rectangular shape composed of a long side width A and a short side width B, and the center of each side end face 23, 23 in the long side width A direction of the fitting part 22 is slightly outward. It is formed in an arc shape when viewed from above so as to protrude toward the top.

  Therefore, the attachment of the side end members 12, 12, the wiring board 14, the translucent plate 10, and the mounting members 20, 20 to the lighting device body 2 will be described with reference to FIGS. The upper surface of the substrate 14 or the lower surface 3b of the central plate-like portion 3 is coated with a double-sided tape or an adhesive having adhesive strength in advance, although not shown in particular. It is attached. In this way, by fixing the wiring board 14 on which the plurality of LEDs 15a are integrally disposed to the lower surface 3b of the central plate-like portion 3, the LEDs 15a can be attached together with the wiring to the lighting device body 2 and can be easily assembled. It becomes.

  Then, the both ends 10a and 10a of the translucent plate 10 are slid and moved to the front and rear lower grooves 6b and 6b from the left and right end surfaces 7 and 7 side of the illuminating device main body 2 to thereby transmit the translucent plate 10. Are guided and mounted in the longitudinal direction. When the translucent plate 10 is attached, the button 16a is temporarily removed from the operation unit 16, so that the collision between the button 16a and the translucent plate 10 can be avoided when the translucent plate 10 slides. At the same time, after the translucent plate 10 is attached, the operation unit 16 can be simply attached simply by inserting the button 16a again from below through the button hole 10c.

  And it inserts and fixes by inserting the insertion pieces 12a and 12a of the side end members 12 and 12 arrange | positioned at the right and left of the illuminating device main body 2 in the upper groove 6a and 6a, and the outer periphery 12b and 12b are the end surfaces 7. , 7 is completed, and the attachment of the side end members 12 and 12 is completed, and the left and right ends of the translucent plate 10 are held by the lower outer peripheral edge 12b and the lateral movement is reliably restrained. There is no need to prepare a new part for holding the plate 10.

  In the illuminating device 1 configured in this way, the plurality of LEDs 15a are simultaneously emitted by the operation of the button 16a, so that sufficient illuminance can be obtained, and the LED 15a is compact in comparison with a conventional fluorescent lamp, so that it is saved. Space can be realized.

  The front and back of the illuminating device main body 2 that is downwardly U-shaped when viewed from the side are covered with the side portions 4 and 4, the left and right end surfaces 7 and 7 are covered with the side end members 12 and 12, and the lower portion is the translucent plate 10. Thus, the illumination light of the LED 15a can be concentrated under the shelf of the shelf plate 33 (see FIG. 2), and sufficient illumination can be given to the space under the shelf. Further, since the plurality of LEDs 15a inside can be completely covered from the outside by the translucent plate 10, the LED 15a can be protected against an impact from the outside, and entry of dust, dust or the like can be prevented.

  Furthermore, since the contact area between the outer surface of the side portions 4 and 4 and the air is expanded by the plurality of grooves 4a and 4a provided on the side portions 4 and 4, the brightness of the LED 15a is high. In addition, the groove shapes (4a, 4a) of the side portions 4, 4 serve as heat radiation fins and exhibit the effect of radiating the heat of the LED 15a to the outside.

  Next, attachment of the attachment members 20 and 20 to the lighting device main body 2 will be described. In order to attach the attachment members 20, 20, when attaching the attachment member 20 to the left and right ends (see FIG. 3) of the upper part of the lighting device main body 2, as shown in FIG. It is placed so that there is a side and it fits within the opening width of the groove. At this time, since the length of the short side width B of the fitting portion 22 is set to be shorter than the groove opening width C, the fitting portion 22 can be easily placed in the groove 3a without contacting the ridges 3d and 3d. Can be made. In addition, the upper and lower thickness of the fitting part 22 is formed in the thickness which can be inserted in the groove 3c, 3c.

  FIG. 7A shows a state in which the fitting portion 22 has a short side and is placed so as to be within the opening width of the groove. The attachment portion 21 is orthogonal to the longitudinal direction of the lighting device body 2 ( It faces outwards (approximately 90 degrees). At this time, since the stepped portion 24 has a height and is formed higher than the height of the groove portion 3a (see FIG. 6), the fitting portions 22 and 22 are easily accommodated in the groove portion 3a.

  The left and right attachment portions 21 and 21 are connected to the left and right side end members 12 while maintaining the state where the fitting portions 22 and 22 are accommodated between the grooves 3c and 3c and are in contact with the bottom of the groove 3a. , 12 side outward (in the direction indicated by the arrow), as shown in FIG. 7 (b), one of the opposite corners of the side faces 23, 23 on both sides of the long side From the side, it is inserted into the front and rear grooves 3c, 3c, and is further rotated in the direction indicated by the arrow, so that both side end surfaces 23, 23 slide along the front and rear grooves 3c, 3c, respectively. It is rotated while being done. In addition, since the horizontal width of the stepped portion 24 is formed smaller than the groove opening width C between the protrusions 3d-3d, both ends of the stepped portion 24 are provided with the groove opening width C when the mounting members 20, 20 are rotated. Smooth rotation is performed without being caught by (between ridges 3d-3d).

  As shown in FIG. 7C, both end portions on the long side of the fitting portion 22 are fitted into the front and rear grooves 3 c, 3 c, and the attachment portions 21, 21 are in the longitudinal direction of the lighting device body 2. , The mounting of the mounting members 20, 20 is completed. In this attached state, the length of the long side A of the fitting portions 22, 22 is longer than the dovetail groove opening width C (between the protrusions 3d-3d) and the dovetail bottom width (between the groove 3c-3c). ) Is equal (or smaller) to prevent the fitting portions 22 and 22 from being detached from the dovetail groove opening width C (between the ridges 3d and 3d), and the mounting members 20 and 20 are securely It is positioned in the dovetail groove 3a.

  Thus, even after the assembly of the lighting device 1, the mounting member 20 is orthogonal to the left and right longitudinal directions of the lighting device body 2 without using tools in the left and right dovetail grooves 3 a, 3 a of the lighting device body 2. Thus, it can be easily moved to the attachment position along the length in the longitudinal direction of the illuminating device body 2 from the front-rear direction displaced by approximately 90 degrees toward the outside of the side end member 12. In addition, when removing the attachment members 20 and 20, it can remove simply by performing the reverse process to attachment.

  Further, the step portions 24 and 24 of the respective mounting members 20 and 20 are moved in the direction indicated by the arrow shown in FIG. 7C until they contact the outer peripheral edges 12b and 12b of the left and right side end members 12 and 12. Thus, the outward movement of the attachment members 20, 20 is restricted. Even when an external pressure is applied to the mounting members 20, 20, the crank-shaped step portions 24, 24 are restricted by the outer peripheral edges 12b, 12b. Can be prevented.

  Therefore, in order to attach the lighting device 1 to which the mounting members 20 and 20 are attached to the shelf plate 33, first, as shown in FIG. 8, a finger is put on the grooves 4a and 4a of the front and rear side portions 4 of the lighting device body 2. Thus, it is possible to simply hold it with one hand simply by lifting it up while preventing slipping of the fingers, and the attachment portion 21 of the attachment member 20 is brought into contact with the lower surface position of the shelf plate 33 with the central plate-like portion 3 as the upper surface.

  At this time, the upper and lower edges 4c and 4c and the lower edges 4b and 4b projecting in the short direction are formed at the vertical positions of the grooves 4a and 4a, so that the positions of the grooves 4a and 4a, which are finger gripping positions, are Therefore, the finger cannot be easily removed from the side portions 4 and 4 while the lighting device 1 is moving. Moreover, since LED15a and the illumination part 15 are lightweight, even if it uses two or more like a present Example, a big load (weight) is not given to the illuminating device main body 2. FIG. In addition, by gripping and moving only the illuminating device main body 2 having a U-shaped cross section with a finger, the translucent plate 10 and the plurality of LEDs 15a are not damaged, and malfunction due to contact with the button 16a does not occur.

  Then, as shown in FIG. 9A, the stepped portion 24 of the mounting member 20 is engaged with the upper side portion of the outer peripheral edge 12b of the side end member 12, so that the mounting member 20 moves outward. Therefore, it is possible to fix and hold the mounting member 20 to the lighting device main body 2 with a simple component configuration without the need for a tool.

  A screw mounting hole 33a is formed on the lower left side of the shelf 33 so as to be perpendicular to the surface of the shelf 33, and the screw insertion hole 21a of the mounting portion 21 of the left mounting member 20 is overlapped with the screw mounting hole 33a. The alignment position is adjusted, and the screw 34 is screwed into the screw mounting hole 33a via the screw insertion hole 21a from below using a tool such as a screwdriver. Although not particularly illustrated, a screw mounting hole 33a is similarly formed on the lower right side surface of the other shelf plate 33, and the lighting device 1 is secured by screwing with the screw 34 via the mounting portion 21 of the right mounting member 20. It is fixed to the bottom surface of the shelf 33 via the left and right mounting members 20, 20.

  Thus, since the attachment part 21 of the attachment member 20 protrudes away from the illuminating device main body 2 and the side end member 12, the shelf board 33 which is a to-be-attached body simply without scratching the illuminating device 1. Can be attached to. And, since only the fitting portion 22 is fitted in the groove 3a in a state where the mounting portion 21 protrudes outward, the side end member 12 prevents the outward movement from the lighting device main body 2 respectively. The lighting device main body 2 can also be restrained from moving in the left-right direction, and it is not necessary to form a mounting portion directly on the lighting device main body 2, so that the length of the lighting device main body 2 can be suppressed and attached without using a tool or the like. The member 20 can be easily assembled to the lighting device main body 2.

  Further, in a state where the mounting member 20 is fixed to the shelf plate 33, the upper surface of the reinforcing member 13 accommodated in the dovetail groove 3a is also brought into contact with the lower surface of the shelf plate 33, so that the lighting device 1 can be more reliably attached. Wobble is prevented. Furthermore, since the reinforcing member 13 is attached, it is possible to prevent the lighting device body 2 from being bent when the lighting device 1 is attached and used. The reinforcing member 13 of this embodiment is preferably made of a hard plastic material, which is preferable because the lighting device 1 can be reduced in weight as well as the rigidity and strength. However, the present invention is not limited to this. Instead, the reinforcing member 13 may be formed of other materials such as metal, and may be a plate member having rigidity.

  However, the present invention is not limited to the lighting device 1 using the reinforcing material 13, and the left and right mounting members 20, 20 are configured even when the reinforcing material 13 is removed from the lighting device body 2 of the present embodiment. Thus, both ends of the lighting device 1 are securely supported and fixed, so that the support strength is sufficiently maintained, and there is no problem when the lighting device 1 is used.

  Then, as shown in FIG. 9B, the lighting device 1 is fixed to the lower surface position of the shelf plate 33 near the upper end in the vicinity of the side end member 12 by using the plate-like mounting member 20, so that the lower side of the shelf plate 33. In addition, the mounting portion of the mounting member 20 does not protrude as much as possible, and the configuration is less noticeable from the outside, so that the appearance of the LED 15a is not caused.

  As described above, by using the plurality of LEDs 15a as the light source, the illumination light of the LEDs 15a can be sufficiently illuminated toward the bottom of the shelf, and the lighting device 1 can be designed to be thin, so that the shelf plate 33 The space under the shelf can be used effectively, and the user who uses the desk 30 is not given a feeling of pressure. Moreover, when removing the illuminating device 1 from the shelf plate 33, as in the case of attaching the illuminating device 1, the groove 4a of the front and rear side portion 4 can be hooked with one hand and held with one hand. Therefore, the removal work can be performed stably in a state where the fingertip is prevented from slipping.

  Although the embodiments of the present invention have been described with reference to the drawings, the specific configuration is not limited to these embodiments, and modifications and additions within the scope of the present invention are included in the present invention. For example, in the above embodiment, the dovetail groove 3a is formed over the entire length in the longitudinal direction by extrusion molding of aluminum of the illuminating device body 2, and thus the weight of the illuminating device body 2 is reduced. However, the present invention is not limited to this, and a dovetail groove to which the pair of attachment members 20 and 20 can be attached may be formed at least on the left and right ends of the central plate-like portion 3.

  Moreover, in the said Example, since the some groove | channels 4a and 4a were formed in the both sides 4 and 4 of the illuminating device main body 2, it is preferable from the ability to prevent a finger | toe slip at the time of attachment or removal of the illuminating device 1, In another embodiment, the grooves 4a and 4a may not be formed, and a fine uneven friction surface may be formed on the outer surface of the side portions 4 and 4 to prevent finger slipping.

  Moreover, in the said Example, since the illumination part 15 provided with LED15a was provided in the wiring board 14 integrally, it is preferable from being easy to attach to the lower surface 3b of the center plate-shaped part 3, but attachment of LED15a of this invention The position is not limited as long as the LED 15a does not block light emission and can be reliably illuminated toward the bottom of the shelf. For example, the LED 15a may be provided below the lower surface 3b of the central plate-shaped portion 3.

  Moreover, in the said Example, although the screw attachment hole 33a was previously formed in the shelf 33 lower surface so that the attachment by the screwing of the screw 34 to the shelf 33 could be performed easily, this invention is limited to this. Instead, the lighting device 1 may be attached to an arbitrary position by directly screwing the screws 34 to the lower surface of the shelf board 33 without forming the screw attachment holes 33a on the lower surface of the shelf board 33. In addition, when attaching the illuminating device 1 to the shelf board of the metal plate which is not shown in figure, you may make it attach with a volt | bolt, a screw, etc. by previously forming an attachment hole in the predetermined location of a shelf board, for example.

  Moreover, in the said Example, although several LED15a is arrange | positioned in a straight line form along the longitudinal direction of the illuminating device main body 2, this invention is not limited to this, The straight LED15a is front and back. A plurality of them may be arranged in parallel to increase the illumination intensity.

  Further, if the attached body is made of iron, a plate-like magnet can be used instead of the reinforcing material.
