  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a perspective view showing an illumination apparatus according to an embodiment of the present invention. FIG. 2 is a cross-sectional view of the luminaire main body 1 and the locking part 5 of FIG. FIG. 3 is a cross-sectional view of the luminaire main body and the locking portion 5 of FIG. 1 cut from the upper direction and the short direction and viewed from the longitudinal direction.

  The luminaire main body 1 of the present embodiment includes a long frame 2, a short frame 3, a translucent panel 4, a locking portion 5, and a light source 7 provided in the luminaire main body 1. In the present embodiment, the outer shape of the luminaire main body 1 is a rectangular parallelepiped. The ceiling attachment portion 6 is provided on the ceiling 10, and the lighting fixture body 1 is attached to the ceiling attachment portion 6 via the locking portion 5. The ceiling mounting portion 6 is linear, and a plurality of lighting fixture bodies 1 are provided.

  Here, the ceiling side when the luminaire main body 1 is attached to the ceiling attachment portion 6 is the upward direction, and the floor side is the downward direction. That is, when the luminaire main body 1 is attached to the ceiling attachment portion 6, the luminaire main body 1 is attached so that the ceiling attachment portion 6, the locking portion 5, and the luminaire main body 1 are arranged in this order from the top to the bottom. Moreover, since the external shape of the lighting fixture main body 1 is a rectangular parallelepiped, the lighting fixture main body 1 has six surfaces. Thereafter, on the basis of the time when the luminaire main body 1 is attached to the ceiling attachment portion 6, the surface on the ceiling side of the luminaire main body 1 is the upper surface, the floor side surface of the luminaire main body 1 is the lower surface, and the ceiling attachment portion 6. The side surface of the luminaire main body 1 that intersects the ceiling mounting portion 6 other than the side surface in the longitudinal direction and the ceiling mounting portion 6 other than the upper surface, the lower surface, and the longitudinal side surface is referred to as the short side surface. Further, hereinafter, a direction parallel to the ceiling and parallel to the ceiling attachment portion 6 is referred to as a longitudinal direction, and a direction parallel to the ceiling and intersecting the ceiling attachment portion 6 is referred to as a short direction.

  The long frame 2 is a concave shape that covers the upper side and the longitudinal side surface of the luminaire body 1. The short frame 3 is plate-shaped so as to cover a part of the lateral side surface of the luminaire main body 1. The translucent panel 4 has a concave shape so as to cover a part of the lower side and the short side of the luminaire main body 1. The outer shape of the locking portion 5 is H-shaped. The lower surface of the locking portion 5 is connected to the long frame 2 that is the upper surface of the lighting fixture body 1. The ceiling mounting portion 6 is a rectangular parallelepiped having a part in the lower surface direction and a short side direction opened. The upper surface of the locking portion 5 is connected to the lower surface of the ceiling mounting portion 6. Although not shown in the figure, a structure for obtaining power from the ceiling mounting portion 6 and transmitting it to the light source 7 is provided in the locking portion 5.

  FIG. 4 is a perspective view of the translucent panel 4. The translucent panel 4 transmits light from the light source 7 and may be transparent or milky white. In this embodiment, the translucent panel 4 is composed of plate-like portions 4a and 4b, and the plate-like portions 4a and 4b are integrally provided. The plate-like portion 4 a is a rectangular plate shape that covers the lower surface of the luminaire main body 1. The plate-like portion 4 b is plate-like so as to cover a part of the lateral side surface of the luminaire main body 1. The plate-like portion 4b is provided at a longitudinal end portion of the plate-like portion 4a so as to be substantially perpendicular to the plate-like portion 4a. The outer shape of the translucent panel 4 is a wide concave shape. The short direction length of the plate-like part 4b is shorter than the short direction length of the plate-like part 4a. This is because the translucent panel 4 is mounted on the mounting portions 2b and 2c of the long frame 2 to be described later and covers a part of the side surface of the luminaire main body 1 in the short direction. Further, the plate-like portion 4b is located at the approximate center of the plate-like portion 4a in the short direction. This is because when the translucent panel 4 is placed on the placement portions 2b and 2c, it is held without interfering with the placement portions 2b and 2c. By making the translucent panel 4 into a concave shape, the light from the light source 7 in the luminaire main body 1 can be transmitted in the short direction, and the light emitting area from the luminaire main body 1 is widened. In addition, since there is no frame at the position where the lower surface of the luminaire main body 1 and the short side surface are in contact with each other, the translucent panel 4 covers the position where the lower surface of the luminaire main body 1 and the short side surface are in contact. When the main body 1 is continuously provided in the longitudinal direction, there is an effect that linearity can be created. In this embodiment, 4a and 4b are integrally provided, but this is not restrictive. As long as the configuration does not cause a shadow at the connection portion between 4a and 4b, they may be separated and combined later.

  FIG. 5 is a perspective view of the long frame 2 as viewed from above. FIG. 6 is a perspective view of the long frame 2 as viewed from below. The long frame 2 includes a long frame upper surface 2a, two long frame longitudinal side surfaces 2f, two mounting portions 2b and 2c, and a substrate mounting portion 2d, respectively. Due to the long frame upper surface 2a and the two long frame longitudinal side surfaces 2f, the outer shape of the long frame 2 has a concave shape. The two long frame side surfaces 2f are provided at both ends 2b of the long frame upper surface 2a so as to be substantially perpendicular to the long frame upper surface 2a. The two mounting portions 2b and 2c are provided on both inner sides of the longitudinal side surface 2f. Neither mounting part 2b * 2c crosses in a transversal direction. If the long frame upper surface 2a is provided at the upper end of the inner surface in the long frame longitudinal direction 2f, the placement portion 2c is provided at the lower end of the inner surface in the long frame longitudinal direction 2f. . The placing portion 2b is provided on the inner surface in the long frame longitudinal direction 2f with a certain distance from the placing portion 2c. Since the plate-like portion 4a of the translucent panel 4 is placed between the placement portions 2b and 2c, the distance between the placement portion 2b and the placement portion 2c is the thickness of the plate-like portion 4a of the translucent panel 4. The above distance is necessary. Here, since the translucent panel 4 should just be mounted, mounting part 2b * 2c does not need to be provided over a longitudinal direction. The substrate platform 2d has a plate shape and is provided so as to extend in the longitudinal direction and the lateral direction of the long frame 2. A light source 7 is placed on the substrate platform 2d. The lighting circuit portion 2e is configured by the upper surface of the long frame 2, the side surface in the longitudinal direction, the substrate mounting portion 2d, and the short frame 3. A lighting circuit (not shown) for lighting the light source 7 is provided in the lighting circuit unit 2e. In order to supply power from the lighting circuit unit 2e to the light source 7, a hole or the like is provided in the substrate platform 2d (not shown). The substrate platform 2d is provided between the upper surface and the lower surface of the luminaire body 1 and above the platform 2b.

  FIG. 7A is a perspective view of the short frame 3 as viewed from the outside of the luminaire main body 1. FIG. 7B is a perspective view of the short frame 3 viewed from the inside of the luminaire main body 1. The short frame 3 has a plate-like concave shape composed of a short frame portion 3a and two short frame portions 3b. By attaching the short frame 3 to the long frame 2, a part of the side surface in the short frame direction of the luminaire main body 1 is covered, and the translucent panel 4 is prevented from falling off the placement portions 2 b and 2 c of the long frame 2. Yes. In this embodiment, screw holes are opened at the four corners of the short frame 3. A screw is passed through the screw hole to connect the short frame 3 and the long frame 2. In the present embodiment, the translucent panel 4 is not connected to the long frame 2 or the short frame 3, but is only locked. However, this is not the case in order to further prevent the translucent panel 4 from falling off by connecting to each.

In this embodiment, the light source 7 is an LED (light emitting diode, light emitting element).
The light source 7 is provided on the substrate platform 2d of the long frame 2. The LED is provided such that the light emitting surface faces downward when attached to the luminaire main body 1. The LED obtains power from a substrate or a lighting circuit. Since the board and the lighting circuit are provided below the LEDs (the lighting circuit, the board, and the LEDs in this order from the top when the luminaire body 1 is mounted on the ceiling 10), the conventional light source uses a fluorescent lamp. Thus, it is not necessary to provide a socket as a power feeding portion at the longitudinal end of the lighting fixture body. This eliminates the shadow frame at the end in the longitudinal direction of the luminaire main body 1, so that linearity can be created when continuously provided.

  Further, in the present embodiment, the short frame 3 is provided in the short direction, but the short direction can be covered with the translucent panel 4 without providing the short frame 3. In that case, it becomes a concave shape having a plate-like portion 4b deeper in the lateral direction than the translucent panel 4 of the present embodiment. Further, in this embodiment, the long frame 2 that covers the upper surface and the longitudinal side surface of the luminaire main body 1 does not need to cover other than the upper surface with the locking portion 5, so the translucent panel 4 includes the direction 5. It is good also as a shape which covers the direction (the longitudinal direction side surface of the lighting fixture main body 1, a transversal direction side surface, and a lower surface). By adopting such a shape, there is an effect that the frame portion is eliminated and the irradiation range is widened.

  FIG. 8 is a perspective view of the lighting device in a state where the translucent panel 4 is removed from FIG. As shown in FIG. 8, the light sources 7 are provided in a line in the longitudinal direction of the substrate mounting portion. By providing one light source 7 in the lighting fixture main body 1 rather than in the longitudinal direction, an effect of increasing the amount of light emitted from the translucent panel 4 is obtained. In addition, since the irradiation range of the light source 7 is determined to some extent, it is possible to extend the irradiation range by arranging the light source 7 in a line rather than one. In this embodiment, the light sources 7 are provided in a line in the longitudinal direction, but this is not restrictive. They may be provided in two rows in the longitudinal direction or in three rows. The irradiation range and the irradiation amount can be increased as the number of the light sources 7 increases. The light source 7 may be provided in combination with a reflector.

  When combining the long frame 2, the short frame 3, and the translucent panel 4, it carries out as follows. The light source 7 is placed on the substrate platform 2d, the lighting circuit unit 2e is provided with a lighting circuit, and the lighting circuit and the light source 7 are connected. The translucent panel 4 is placed between the placing portions 2 b and 2 c of the long frame 2. At this time, the translucent panel 4 is slid along the longitudinal direction from one short side surface of the long frame 2 to the other short side surface to place the translucent panel 4. By the operation so far, the long frame 2 is in a state where the lower surface and a part of the side surface in the short direction are covered with the translucent panel 4. All the lateral sides in the short direction are not covered, and the translucent panel 4 is just placed on the placement portion 2c and moves in the longitudinal direction. If the translucent panel 4 moves as an illuminating device, there is a risk of the translucent panel 4 falling. And is connected to the long frame 2 with screws or the like. Thereby, the base type illumination which is covered with the translucent panel from the lower surface of the illuminating device main body 1 to a part of the side surface in the short-side direction and does not obstruct the light from the light source such as a frame is created.

  FIG. 9 is a perspective view when the luminaire main body 1 according to the embodiment of the present invention is arranged so as to be continuous in the longitudinal direction of the luminaire main body. FIG. 10 is a perspective view of the luminaire main body 1 of FIG. 9 when viewed from the lateral side. FIG. 11 is a perspective view of the luminaire main body 1 when attached to the ceiling 10.

  When the luminaire main body 1 is arranged so as to be continuous in the longitudinal direction, there is no portion that obstructs irradiation from the light source 7 in the longitudinal direction (portion conventionally shaded by a short frame). As a result, when the illumination device is viewed from other than the joint between the illumination devices, it looks as if there is one long illumination device, and linearity is created.
