Description

  Embodiments described herein relate generally to a lighting fixture including a pair of attachment springs.

  Conventionally, as a lighting fixture, there is a downlight embedded in a ceiling board. In this lighting fixture, a mounting spring for ceiling mounting is disposed on a side surface of a cylindrical fixture main body, and a top plate is attached to an upper portion of the fixture main body. The top plate is provided with a projecting portion for forming a terminal block attachment region that projects to the side of the instrument body and attaches the terminal block.

  In this lighting fixture, a pair of attachment springs may be used. In this case, the pair of mounting springs are disposed at symmetrical positions with respect to the center of the instrument body, and the protrusions of the top plate are disposed in the direction in which the pair of mounting springs are disposed in order to avoid interference with the mounting springs. It protrudes in the direction orthogonal to.

  Since the projecting portion of the top plate projects in a direction perpendicular to the direction in which the pair of mounting springs are arranged, when the lighting fixture is installed on the ceiling plate, the pair of mounting plates and the top plate project on the ceiling. It is necessary that there are no obstacles such as beams behind the ceiling in three directions.

  Therefore, depending on the obstacle behind the ceiling, installation of the lighting apparatus may be restricted. For example, when two obstacles are lined up on the back of the ceiling, the mounting spring or the protruding part of the top plate interferes with the obstacle even when trying to install the lighting fixture between the two obstacles. Installation is limited.

The protruding portion 40 is asymmetric with respect to the direction in which the pair of mounting springs 21a and 21b is disposed, and is arranged at a position shifted from the center line in the direction perpendicular to the direction in which the pair of mounting springs 21a and 21b are disposed. It is installed. That is, the position of the protruding portion 40 in the circumferential direction of the instrument body 20 is between the pair of mounting springs 21a and 21b, and the interval or angle between the protruding portion 40 and one mounting spring 21a is the mounting position of the protruding portion 40 and the other. It is in a position narrower than the distance or angle between the spring 21b.

  As shown in FIG. 1, the projecting direction of the projecting portion 40 is larger than 0 ° when the arrangement direction of the pair of mounting springs 21a and 21b in the circumferential direction of the instrument body 20 is 0 °, and a pair of mountings. It is within a range smaller than 90 ° perpendicular to the arrangement direction of the springs 21a and 21b. When the protruding portion 40 protrudes in the direction of 0 °, one mounting spring 21a interferes with the protruding portion 40, and when the protruding portion 40 protrudes in the direction of 90 °, a pair of mounting springs 21a , 21b has a large projecting amount to the side perpendicular to 21b, and the installation of the lighting fixture 10 is likely to be limited. In consideration of relaxing restrictions on the installation of the lighting fixture 10, the protrusion 40 is preferably close to the one mounting spring 21a within a range that does not interfere with the one mounting spring 21a, and therefore, a more preferable range is 0 °. Larger than and less than 45 °, and the angle α in the present embodiment is 30 °.

  The protruding portion 40 has an extending portion 43 extending in a tangential direction from the outer periphery of the top plate portion 39, and protrudes from the extending portion 43 in a predetermined protruding direction.

Can be relaxed.

  Furthermore, considering that the restriction on the installation of the luminaire 10 is more relaxed, it is preferable that the protruding portion 40 is close to the one mounting spring 21a as long as it does not interfere with the one mounting spring 21a. Therefore, the range is preferably a range larger than 0 ° and smaller than 45 °. For example, if the range is 30 °, the restriction on the installation of the lighting fixture 10 can be relaxed more reliably.

  Further, the protrusion 40 has an extension 43 extending in a tangential direction from the outer periphery of the top plate portion 39, and protrudes from the extension 43 toward a predetermined protrusion direction, as shown in FIG. A wiring space for the internal wiring between the instrument body 20 side, that is, the socket 23 and the terminal block 24 can be secured in the protruding portion 40.

  Next, FIG. 8 shows a second embodiment. In addition, about the same structure as 1st Embodiment, the description of the structure and effect is abbreviate | omitted using the same part number.

  The protruding portion 40 of the top plate 22 protrudes in parallel with the one attachment spring 21a.

  In this case, when the arrangement direction of the pair of attachment springs 21a and 21b in the circumferential direction of the instrument body 20 is 0 °, the protruding portion 40 protrudes in a range larger than 0 ° and smaller than 90 °. .

  In this case as well, the position of the protruding portion 40 in the circumferential direction of the instrument body 20 is between the pair of mounting springs 21a and 21b, and the interval or angle between the protruding portion 40 and one mounting spring 21a is the protruding portion. It is in a position narrower than the interval or angle between 40 and the other mounting spring 21b.

  Therefore, also in the lighting fixture 10 of 2nd Embodiment, there exists an effect similar to 1st Embodiment mentioned above.

  Note that the lighting fixture 10 is not limited to the lamp device 11 that is detachable, but may be a fixture in which the light source is fixed to the fixture body 20 or the top plate 22. In this case, the power supply circuit may be attached to the protruding portion 40 of the top plate 22 together with the terminal block 24.

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention.
