Description

  The present invention relates to a lighting fixture that houses and holds a lamp tube, and a lighting fixture assembly in which a plurality of lighting fixtures are connected to each other.

  A luminaire using a cold cathode fluorescent lamp (CCFL) generally stores and holds a fluorescent lamp tube in a recess of a cover case. When a plurality of fluorescent lamp tubes are held in the cover case, the fluorescent lamp tubes are arranged in parallel. The inner surface of the concave portion of such a cover case is used as a reflecting surface that is coated with white paint to increase light efficiency and diffuses light.

Conventionally, when it is desired to secure a sufficient illumination area and light quantity with such a lighting fixture, a plurality of lighting fixtures are sometimes installed side by side (see Patent Document 1).
JP 2004-149303 A

  When installing a plurality of lighting fixtures as described above, as shown in FIG. 3, the two lighting fixtures 1 are arranged so that the side walls 3 a of the cover cases 3 facing the ends of the fluorescent lamp tube 2 in the tube axis direction are arranged. You may want to install them in close proximity.

  However, in the case of this arrangement, the side wall 3a at the end of the cover case cannot sufficiently diffuse the light, and the illumination around the vicinity of the side wall 3a (range A in FIG. 3) becomes darker than the others. was there.

  An object of the present invention is to provide a lighting fixture that can solve the above-described problems of the background art and a lighting fixture assembly that connects the plurality of lighting fixtures. An example of the purpose is to keep the illumination light amount of the entire plurality of lighting fixtures uniform even when a plurality of lighting fixtures are arranged in the tube axis direction of the fluorescent lamp tube.

  One embodiment of the present invention is a lighting fixture including a cover case that houses and holds a lamp tube. In this lighting fixture, the side wall portions of the cover case facing the both ends in the tube axis direction of the lamp tube to be held can be removed. The portion of the cover case corresponding to the end portion in the tube axis direction of the lamp tube can be connected to another lighting fixture.

  Another aspect of the present invention is a connecting member for connecting the above-described lighting fixture to another lighting fixture. This consists of a light-transmitting cover attached to the cover case so as to cover the end of the lighting fixture corresponding to the end of the lamp tube in the tube axis direction.

  Furthermore, another aspect of the present invention is a lighting device assembly formed by connecting a plurality of lighting fixture bodies each having a cover case that houses and holds a lamp tube. This assembly includes a transparent connecting member that connects one lighting device and another lighting device in the tube axis direction of the lamp tube. And in the connection part of each lighting fixture, the side wall part of the cover case which each opposes the tube-axis direction both ends of the lamp tube to hold | maintain is removed.

  According to the present invention, even if a plurality of lighting fixtures are arranged in the tube axis direction of the fluorescent lamp tube, the illumination light quantity of the plurality of lighting fixtures can be kept uniform.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view showing a lighting fixture according to an embodiment of the present invention, and FIG. 2 is a plan view showing a lighting fixture assembly formed by connecting a plurality of lighting fixtures according to the present invention.

  As shown in this figure, the luminaire 1 of this example includes a cover case 3 for storing and holding two fluorescent lamp tubes 2 in parallel. The cover case 3 has a box shape without a lid, and white paint is applied to the inner surface to improve the reflection efficiency. In this example, the cover case 3 for housing the two fluorescent lamp tubes 2 is shown, but the present invention is not limited to this.

  The cover case 3 has a structure in which the side wall portions 3a facing the both ends in the tube axis direction of the fluorescent lamp tube 2 to be held can be removed. For example, the side wall portion 3a is provided separately from the cover case 3, and is fixed to the cover case 3 with screws so that the side wall portion 3a can be easily removed when it is desired to be removed.

  A portion of the cover case 3 corresponding to the tube axial direction end of the fluorescent lamp tube 2 can be connected to another same lighting device 1.

  The connecting member for connecting the same lighting fixtures 1 is a light transmitting property that is attached to the cover case 3 so as to cover an end portion of one lighting fixture 1 corresponding to the end portion of the fluorescent lamp tube 2 in the tube axis direction. It consists of a cover 4.

  In the above configuration, when the same lighting fixtures 1 are installed so that their end portions are close to each other, first, the predetermined side wall portion 3a of the cover case 3 of each lighting fixture 1 is removed. Next, the two luminaires 1 are installed with their end portions close to each other with the side wall portion 3a removed. At this time, the ends of the two adjacent lighting fixtures 1 are covered with the light-transmitting cover 4 and connected and fixed. The cover 4 is formed of a cylindrical transparent acrylic plate or the like. The end of each lighting device 1 to be brought close is fitted into the cylindrical cover 4 and then the cover 4 is fixed to the cover case 3 with screws.

  In this way, a lighting device assembly (lighting assembly) 5 formed by connecting a plurality of lighting fixtures 1 is a transparent device that connects one lighting fixture 1 and another lighting fixture 1 in the tube axis direction of the fluorescent lamp tube 2. It has a light transmissive cover 4 which is a connecting member. And in each lighting fixture 1, the side wall part 3a of the cover case 3 which each opposes the both ends of the axial direction of the fluorescent lamp tube 2 to hold | maintain is removed.

  As a result, the luminaire assembly of the present invention can sufficiently diffuse light even at the connecting portion, so that the illumination light amount of the entire luminaire assembly becomes uniform, and the safety due to the removal of the side wall portion 3a is also covered. Can be secured.

  In the above embodiment, the lighting apparatus using the fluorescent lamp tube has been described. However, the present invention can also be applied to a lighting apparatus using an LED lamp instead of the fluorescent lamp tube.

  As described above, the present invention has been described with reference to the embodiments. However, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the technical concept thereof. Needless to say.

It is a perspective view which shows the lighting fixture by one Example of this invention. It is a top view which shows the lighting fixture assembly formed by connecting two or more lighting fixtures by this invention. It is a top view which shows the lighting fixture by related technology.
