A plurality of LEDs are turned on.

  FIG. 11 is a partial perspective view illustrating a state where the connection between the light source unit 30 and the lighting fixture 20 by the mounting spring 45 of the lighting device 10 is released.

  As shown in FIG. 11, the engaging portion 63 has an L-shaped cross section, and includes a fixing portion 64 and an insertion portion 65. The fixing portion 64 is fixed to the back surface of the mounting member 61. The insertion portion 65 is formed with a rectangular through hole 66 for inserting the attachment spring 45. The light source unit 30 is mounted on the lighting fixture 20 by inserting the attachment spring 45 into the through hole 66. When the light source unit 30 is pulled away from the lighting fixture 20 and the mounting spring 45 is removed from the through hole 66 in the state shown in FIG. 10, the connection between the light source unit 30 and the lighting fixture 20 is released.

  Below, the procedure in which an operator attaches the light source unit 30 to the lighting fixture 20 installed on the ceiling is demonstrated.

  One end in the longitudinal direction of the attachment spring 45 corresponds to the root, and the other end in the longitudinal direction corresponds to the tip. The base of the mounting spring 45 is fixed to the inner upper surface of the housing recess 41 of the lighting fixture 20 with a screw or the like. The attachment spring 45 exerts an elastic force in a direction in which the tip hits the inner upper surface of the housing recess 41 of the lighting fixture 20. Therefore, in a state where the light source unit 30 is completely separated from the lighting fixture 20, the tip of the attachment spring 45 hits the inner upper surface of the receiving recess 41 of the lighting fixture 20 and presses the receiving recess 41. At this time, the attachment spring 45 is curved so as to bend downward (in the direction of gravity).

  From the state in which the light source unit 30 is completely separated from the lighting fixture 20 as described above, first, the operator applies a force against the elastic force to the mounting spring 45 to bring the mounting spring 45 into a vertical state. To be elastically deformed. The vertical state is a state in which the tip of the mounting spring 45 is located near the base of the longitudinal direction away from the housing recess 41. In this state, the attachment spring 45 extends in the vertical direction and is almost straight. The operator inserts the tip of the mounting spring 45 into the through hole 66 of the engaging portion 63 during or after the process of bringing the mounting spring 45 into the vertical state. Thereby, the illuminating device 10 will be in the state shown in FIG. The tip of the mounting spring 45 is bent, and the bent portion is hooked on the periphery of the through hole 66 of the engaging portion 63. Therefore, in the state illustrated in FIG. 10, the light source unit 30 is suspended from the lighting fixture 20. At this time, the attachment springs 45 are arranged one by one at positions close to both ends in the longitudinal direction (length direction) of the lighting fixture 20, and hold the light source unit 30 in a state substantially parallel to the lighting fixture 20. . Therefore, the operator does not need to support the light source unit 30 by hand. For example, when the lighting device 10 is constructed, the operator can easily perform an operation of connecting the power terminal block connector and the power device connector.

  Next, the operator lifts the light source unit 30. At this time, the attachment spring 45 slides with respect to the peripheral edge of the through hole 66 of the engaging portion 63 by elastic force, and is gradually inserted into the through hole 66 up to a portion close to the root. And the attachment spring 45 finally returns to the original state. In the original state, the tip of the mounting spring 45 hits the inner upper surface of the housing recess 41 of the lighting fixture 20 and presses the housing recess 41. At this time, as shown in FIG. 8, the attachment spring 45 is curved so as to bend downward (in the direction of gravity). The attachment spring 45 has an elastic force enough to hold the light source unit 30. Therefore, the light source unit 30 is fixed to the lighting fixture 20. In this state, a part of the light source unit 30 (power supply device 32 or the like) is housed in the housing recess 41 of the lighting fixture 20, but other parts such as the light transmissive cover 62 are exposed below the housing recess 41. To do. As for the protrusion piece 52 of the light source unit support part 24 of the lighting fixture 20, the front-end | tip part contacts the light transmissive cover 62 (the attachment member 61 may be sufficient). Therefore, the light transmissive cover 62 is separated from the horizontal plane portion 42 of the lighting fixture 20 by the length of the protruding piece 52 with respect to the mounting direction (vertical direction) of the light source unit 30. That is, there is a gap between the light transmissive cover 62 and the horizontal surface portion 42 of the lighting fixture 20.

  Below, the procedure in which an operator removes the light source unit 30 from the lighting fixture 20 is demonstrated.

  The procedure for removing the light source unit 30 is the reverse of the procedure for attaching the light source unit 30.

  As described above, in a state where the light source unit 30 is attached to the lighting fixture 20, the tip of the mounting spring 45 hits the inner upper surface of the receiving recess 41 of the lighting fixture 20 and presses the receiving recess 41. At this time, the attachment spring 45 is curved so as to bend downward (in the direction of gravity).

  First, the operator pulls down the light source unit 30. At this time, the attachment spring 45 slides with respect to the peripheral edge of the through hole 66 of the engaging portion 63 by the elastic force, and gradually comes out of the through hole 66 from the portion near the base. Then, the attachment spring 45 finally becomes a vertical state as shown in FIG.

  Next, the operator pulls out the tip of the attachment spring 45 from the through hole 66 of the engaging portion 63. Thereby, the attachment spring 45 returns to the original state by an elastic force. If the connection between the power terminal block connector and the power supply device connector is released, the light source unit 30 can be completely separated from the lighting fixture 20.

  12 and 13 are partial perspective views showing how the tool 71 is used when the light source unit 30 of the lighting apparatus 10 is pulled away from the lighting fixture 20.

  In the present embodiment, the light source unit support portion 24 (particularly, the protruding piece 52) of the lighting fixture 20 protrudes from the opening of the storage recess 41 and hits the upper surface of the light-transmitting cover 62 of the light source unit 30, whereby the storage recess 41. The above-described gap is provided between the peripheral edge of the opening and the upper surface of the light-transmitting cover 62. Therefore, when removing the light source unit 30, the operator pulls down the light source unit 30 by grasping the upper corners of one or both ends of the light-transmitting cover 62 in the short direction (width direction) of the light source unit 30 with fingers. be able to. That is, in the present embodiment, a distance corresponding to the length of the protruding piece 52 is maintained between the horizontal surface portion 42 of the lighting fixture 20 and the upper surface of the light-transmitting cover 62, so that the vertical surface portion 43 of the lighting fixture 20 is maintained. Even if the distance between the light-transmitting cover 62 and the light-transmitting cover 62 is shortened, both ends of the light-transmitting cover 62 in the short direction (width direction) of the light source unit 30 can be picked with the fingers. However, if it is still difficult to lower the light source unit 30, the operator may lower the light source unit 30 using a tool 71 as shown in FIGS. 12 and 13.

  For example, first, as shown in FIG. 12, the worker uses a rod-shaped tool 71 (for example, a hexagon wrench) having a bent tip, a longitudinal direction (long) of one end plate 44 of the lighting fixture 20 and the light source unit 30. The tip of the tool 71 is hooked on the upper surface of the light-transmitting cover 62. Next, as shown in FIG. 13, the operator pulls the tool 71 downward to lower the light source unit 30. Thereby, the light source unit 30 can be pulled down easily.

  In the present embodiment, since the light source unit support 24 is provided between the fixture body 21 and the light source unit 30 of the lighting fixture 20, the light source unit 30 can be easily removed even if the opening width of the fixture body 21 is narrow. be able to. Therefore, the size of the lighting fixture 20 visible from the ceiling surface can be reduced. In addition, since the distance between the light source unit 30 and the vertical surface portion 43 of the lighting fixture 20 can be shortened, a desired light blocking angle can be obtained without attaching the light source unit 30 to the recessed position of the fixture main body 21. Therefore, the height of the instrument body 21 can be reduced.

  In the present embodiment, the mounting springs 45 are installed at two locations in the longitudinal direction (length direction) of the lighting fixture 20, but the mounting springs 45 are arranged in the longitudinal direction (length direction) of the lighting fixture 20. It suffices if it is installed in at least one place. Further, the attachment spring 45 may be installed in at least one place in the longitudinal direction (length direction) of the light source unit 30 instead of being installed in the lighting fixture 20. In that case, the engaging part 63 is installed in the lighting fixture 20.

Embodiment 2. FIG.
In the present embodiment, differences from the first embodiment will be mainly described.

  FIG. 14 is an exploded perspective view of lighting device 10 according to the present embodiment.

  As illustrated in FIG. 14, the lighting device 10 includes the lighting fixture 20 and the light source unit 30 as in the first embodiment. In the present embodiment, the configuration of the light source unit support portion 24 of the lighting fixture 20 is provided. However, it differs from that of the first embodiment shown in FIG.

  There is a step between the light transmissive cover 62 of the light source unit 30 and the light transmissive cover 62. The level difference exists at both ends in the short direction (width direction) of the light source unit 30. That is, the light source unit 30 is provided with stepped surfaces facing the lighting fixture 20 at both ends in the short direction (width direction). This step surface extends in the entire longitudinal direction (length direction) of the light source unit 30. The present embodiment can be applied if the step surface is provided at least at one end in the short direction (width direction) of the light source unit 30.

  As in the first embodiment, the light source unit support 24 of the lighting fixture 20 has a plate-like portion protruding from the opening of the housing recess 41 of the lighting fixture 20 in the longitudinal direction (length direction) of the lighting fixture 20. It extends to. In the present embodiment, the light source unit support 24 is provided with a notch 81.

  Here, on the step surface of the light source unit 30, a region for hooking the tool 71 or fingers is a first region, and a region adjacent to the first region in the longitudinal direction (length direction) of the light source unit 30 is a second region. . At this time, the notch 81 of the light source unit support 24 is provided at a position corresponding to the first region of the step surface of the light source unit 30. By providing the notch 81 at this position, the light source unit support 24 can be prevented from hitting the first region of the step surface of the light source unit 30. That is, the light source unit support portion 24 protrudes from the opening of the housing recess 41 and hits the step surface of the light source unit 30, so that the gap between the peripheral edge (horizontal plane portion 42) of the opening of the housing recess 41 and the step surface of the light source unit 30. If a light source unit support portion 24 is present even if the tool 71 or fingers are to be inserted into the gap, the tool 71 or fingers cannot actually be inserted or is difficult to insert. End up. Therefore, in the present embodiment, the light source unit support portion 24 contacts only the second region of the step surface of the light source unit 30, and the gap between the horizontal surface portion 42 and the first region of the step surface of the light source unit 30 is set. The light source unit support 24 is hardly present (the notch 81 is present). Therefore, according to the present embodiment, the tool 71 or the finger can be easily inserted into the gap between the horizontal surface portion 42 and the first region of the step surface of the light source unit 30.

  When removing the light source unit 30, the operator hooks the tool 71 or fingers on the stepped surface of the light source unit 30 and pulls the light source unit 30 away from the lighting fixture 20. At this time, the operator can easily hook the tool 71 or fingers on the first area (the position where the notch 81 is present) where the light source unit support portion 24 is not in contact with the stepped surface of the light source unit 30.

  When the light source unit 30 is pulled away from the lighting fixture 20, as in the first embodiment, a force is applied to the mounting spring 45 in the direction opposite to the direction of the elastic force, and the light source unit 30 and the lighting fixture 20 by the mounting spring 45 are Is disconnected. Thereby, the light source unit 30 is removed from the lighting fixture 20.

  The notch 81 of the light source unit support 24 is desirably provided at the same position as the location where the attachment spring 45 is installed in the longitudinal direction (length direction) of the lighting fixture 20. This is because, in the longitudinal direction (length direction) of the light source unit 30, it is efficient to pull down the light source unit 30 by hooking the tool 71 or fingers at a position corresponding to the location where the mounting spring 45 is installed. Therefore, when the mounting spring 45 is installed in at least one place in the longitudinal direction (length direction) of the light source unit 30 instead of being installed in the lighting fixture 20, the notch 81 of the light source unit support portion 24 is In the longitudinal direction (length direction) of the lighting fixture 20, it is desirable to be provided at a position corresponding to the location where the mounting spring 45 of the light source unit 30 is installed.

  In this embodiment, since it is easy to hook the tool 71 or fingers on the step surface provided at least at one end in the short direction (width direction) of the light source unit 30, the instrument main body 21 in the first embodiment is Even if the opening width is narrow, the effect that the light source unit 30 can be easily removed is further enhanced.

  In the present embodiment, the notches 81 of the light source unit support 24 are provided at four locations, but the number of the notches 81 can be changed as appropriate.

Embodiment 3 FIG.
In the present embodiment, differences from the first embodiment will be mainly described.

However, it differs from that of the first embodiment shown in FIG.

  There is a step between the light transmissive cover 62 of the light source unit 30 and the light transmissive cover 62. The level difference exists at both ends in the short direction (width direction) of the light source unit 30. That is, the light source unit 30 is provided with stepped surfaces facing the lighting fixture 20 at both ends in the short direction (width direction). This step surface extends in the entire longitudinal direction (length direction) of the light source unit 30. The present embodiment can be applied if the step surface is provided at least at one end in the short direction (width direction) of the light source unit 30.

  On the step surface of the light source unit 30, a recess 82 for hooking the tool 71 or fingers is formed.

  As in the first embodiment, the light source unit support 24 of the lighting fixture 20 has a plate-like portion protruding from the opening of the housing recess 41 of the lighting fixture 20 in the longitudinal direction (length direction) of the lighting fixture 20. It extends to. The light source unit support portion 24 protrudes from the opening of the housing recess 41 and hits the step surface of the light source unit 30, so that a gap is formed between the peripheral edge (horizontal surface portion 42) of the opening of the housing recess 41 and the step surface of the light source unit 30. Although it is vacant, even if the tool 71 or fingers are to be inserted into the gap, if the light source unit support 24 is present, the tool 71 or fingers cannot actually be inserted or it is difficult to insert them. . Therefore, in the present embodiment, the recess 82 is formed in the step surface of the light source unit 30 so that the light source unit support portion 24 does not hit a part of the step surface of the light source unit 30. Therefore, according to the present embodiment, the tool 71 or the finger can be easily inserted into the recess 82 on the step surface of the light source unit 30.

  When removing the light source unit 30, the operator hooks the tool 71 or fingers on the stepped surface of the light source unit 30 and pulls the light source unit 30 away from the lighting fixture 20. At this time, the operator can easily hook the tool 71 or fingers on the step 82 of the light source unit 30 to the recess 82 where the light source unit support 24 does not hit.

  When the light source unit 30 is pulled away from the lighting fixture 20, as in the first embodiment, a force is applied to the mounting spring 45 in the direction opposite to the direction of the elastic force, and the light source unit 30 and the lighting fixture 20 by the mounting spring 45 are Is disconnected.
