  The cover 14 is formed in a cylindrical shape that opens up and down. The cover 14 is made of a light transmissive material. On the inner peripheral surface of the cover 14, a screw portion 50 that is a female screw that is screwed into the screw portion 31 of the adapter 13 is formed. The screw portion 50 is disposed in the central area in the vertical direction of the cover 14. Further, the cover 14 is configured to have different light distribution characteristics on one end side and the other end side in the vertical direction. For example, a light distribution member 51 such as a seal is attached to one end side of the cover 14. The cover 14 can be attached to the adapter 13 in a state where one end side and the other end side of the cover 14 are directed upward. Further, the cover 14 is held by being screwed onto the adapter 13 so that the upper end of the cover 14 is in contact with the ceiling surface A.

  The lighting fixture 10 configured in this manner is smaller in the diameter of the hooking ceiling body 11 and the lamp device 12 than the diameter of the adapter 13, and the cover 14 is formed in a diameter approximate to the diameter of the adapter 13, and is configured compactly. ing.

  In order to install the lighting fixture 10 on the hanging ceiling body 11 on the ceiling surface A, the adapter 13 is attached to the hanging ceiling body 11, the lamp device 12 is attached to the adapter 13, and the cover 14 is screwed to the adapter 13.

  When the lamp device 12 is attached to the adapter 13, the base 21 of the lamp device 12 is attached to the socket device 30 of the adapter 13. Then, the pair of key grooves 24 (vertical groove portions 24 a) of the base 21 are aligned with the pair of keys 46 of the socket device 30, and the protruding portions 22 of the base 21 are inserted into the insertion holes 34 of the socket device 30. As a result, the base 21 is inserted in a state of being positioned with respect to the socket device 30, and the pair of lamp pins 23 is inserted into the insertion holes 39 of the pair of mounting holes 38 (two-dot chain line position in FIG. 1). When the base 21 is inserted into the socket device 30 to a predetermined insertion position, the large diameter portion 26 of the lamp pin 23 is disposed above the support portion 42.

  The base 21 inserted in the socket device 30 is rotated in a circumferential direction corresponding to a predetermined mounting direction. As a result, the large-diameter portion 26 of the lamp pin 23 moves onto the support portion 42, and the pin portion 25 moves within the long hole portion 40. Further, the lateral groove portion 24 b of the key groove 24 is fitted into the key 46.

  After the lamp pin 23 is moved to the mounting position P, when the push-up of the lamp device 12 is released, the large diameter portion 26 of the lamp pin 23 falls into the recessed portion 44 and the lamp pin 23 is held at the mounting position P.

The lamp device 12 is urged downward with respect to the socket device 30 by the repulsive force of the elastic body 47. Therefore, the state where the large diameter portion 26 of the lamp pin 23 falls into the recessed portion 44 is maintained.

  A terminal 33 is electrically connected to the lamp pin 23 moved to the mounting position P. As a result, AC power can be supplied from the hooking sealing body 11 to the lamp device 12 through the adapter 13.

  Then, when the AC power is supplied to the lamp device 12, the DC power converted by the lighting circuit 19 is supplied to the light source 18, the light source 18 is turned on, and the light transmitted through the translucent cover 20 is irradiated downward. The Part of the light that has passed through the translucent cover 20 enters the cover 14. At this time, when the cover 14 is attached to the adapter 13 with the end on the orientation member 51 side as the lower side, the light from the lamp device 12 is blocked or transmitted through the orientation member 51 in accordance with the orientation member 51, On the other hand, when the cover 14 is attached to the adapter 13 with the end on the orientation member 51 side as the upper side, the cover 14 transmits light from the lamp device 12.

  In addition, when the lamp device 12 is attached to the socket device 30, the lamp device 12 is attached in the direction opposite to the mounting direction, for example, when the lamp device 12 is touched when the cover 14 is rotated to attach or detach the adapter 14. Assume that an external force is applied in the outward direction. In this case, even if the lamp pin 23 is about to rotate together with the base 21 in the removal direction, the large diameter portion 26 of the lamp pin 23 comes into contact with the stepped portion 45, and the rotation of the base 21 in the removal direction is suppressed. As a result, since the lamp pin 23 is held at the mounting position P, it is possible to prevent the lamp pin 23 from being displaced, resulting in poor electrical connection with the terminal 33, and the lamp pin 23 from falling off the socket device 30. Can do.

  In order to remove the lamp device 12 from the socket device 30, such as when the lamp device 12 is replaced, the base 21 is rotated in the outward direction. Thereby, the large-diameter portion 26 of the lamp pin 23 comes into contact with the stepped portion 45, and once the rotation of the base 21 is suppressed, by rotating the base 21 strongly or pushing up the base 21, The large-diameter portion 26 of the lamp pin 23 gets over the step portion 45 and moves onto the support portion 42. Further, the large-diameter portion 26 of the lamp pin 23 moves onto the insertion hole 39, so that the lamp pin 23 can be pulled down from the insertion hole 39 and the lamp device 12 can be removed from the socket device 30.

  According to the socket device 30 of the present embodiment, the reverse rotation suppression means 43 can prevent the lamp device 12 rotated to the mounting position P from rotating in the reverse direction, so that the lamp device 12 is misaligned or dropped. Can be prevented.

  Further, the reverse rotation suppression means 43 can be provided on the support portion 42 that supports the lamp pin 23 rotated from the insertion hole portion 39 of the mounting hole 38 to the long hole portion 40. Can be configured.

  Furthermore, since the reverse rotation suppressing means 43 is configured by the hollow portion 44 that is recessed from the support portion 42, the reverse rotation suppressing means 43 can be easily configured and the lamp pin 23 can be securely held.

  Further, since the screw portion 50 is disposed in the central area between both ends of the cover 14, the cover 14 can be attached to the adapter 13 even when both ends of the cover 14 are directed upward. If the light distribution characteristics are different between the one end side and the other end side of the cover 14, any light distribution can be selected by changing the mounting direction of the cover 14.

  Next, FIG. 5 shows a second embodiment. In addition, the same code | symbol is used about the same structure as 1st Embodiment, and the description of the structure and effect is abbreviate | omitted.

  The reverse rotation suppressing means 43 is constituted by a protrusion 54 protruding upward from the support portion 42 before the mounting position P.

  Then, when the lamp device 12 is mounted on the socket device 30, the large diameter portion 26 of the lamp pin 23 is supported by the support portion 42 by rotating the base 21 inserted in the socket device 30 in the circumferential direction corresponding to the mounting direction. The pin portion 25 moves in the long hole portion 40 as it moves upward. Before the lamp pin 23 rotates to the mounting position P, the large diameter portion 26 of the lamp pin 23 comes into contact with the projection 54. Therefore, by rotating the base 21 strongly or pushing the base 21 upward, The large diameter portion 26 gets over the protrusion 54. When the large-diameter portion 26 of the lamp pin 23 gets over the protrusion 54, the lamp pin 23 is disposed at the mounting position P. The click feeling when the large-diameter portion 26 of the lamp pin 23 falls over the protrusion 54 makes it easy for the operator to know that the base 21 has been attached to the socket device 30.

  In addition, in the state where the lamp device 12 is attached to the socket device 30, if an external force is applied to the lamp device 12 in the removal direction opposite to the attachment direction, the lamp pin 23 together with the base 21 may rotate in the removal direction. The large-diameter portion 26 of the lamp pin 23 comes into contact with the protrusion 54, and the rotation of the base 21 in the removal direction is suppressed. As a result, since the lamp pin 23 is held at the mounting position P, it is possible to prevent the lamp pin 23 from being displaced, resulting in poor electrical connection with the terminal 33, and the lamp pin 23 from falling off the socket device 30. Can do.

  In order to remove the lamp device 12 from the socket device 30, such as when the lamp device 12 is replaced, the base 21 is rotated in the outward direction. As a result, the large-diameter portion 26 of the lamp pin 23 comes into contact with the protrusion 54, and once the rotation of the base 21 is suppressed, the lamp pin 21 can be rotated by rotating the base 21 strongly or pushing the base 21 upward. The large diameter portion 26 of 23 gets over the protrusion 54. Further, the large-diameter portion 26 of the lamp pin 23 moves onto the insertion hole 39, so that the lamp pin 23 can be pulled down from the insertion hole 39 and the lamp device 12 can be removed from the socket device 30.
