The locking protrusion 211 protrudes inward in the radial direction, and selectively engages with one of the two locking claws 322 of the pair of locking pieces 321 of the unit side locking portion 320. When the conventional round fluorescent lamp is mounted and used, the fixture side locking portion 210 has the same configuration as the unit side locking portion 320 of the lighting fixture mounting apparatus 300 as described as an example of the prior art. And engages with the upper adapter of the luminaire fixture that does not include the LED lamp power supply unit 330.

  The fluorescent lamp power supply unit 220 receives the commercial power from the power supply outlet 801 and functions to turn on the round fluorescent lamp. A power receiving cable 223 extends from the fluorescent lamp power supply unit 220. However, the power receiving cable 223 is connected to the above-described conventional adapter of the lighting fixture and is not used in this embodiment. Two fluorescent lamp cables 221 extend from the fluorescent lamp power supply unit 220. A fluorescent lamp connector 222 is attached to the tip of each fluorescent lamp cable 221. The fluorescent lamp connector 222 can be connected to a round fluorescent lamp connector. In the present embodiment, the fluorescent lamp connector 222 is connected to the dummy connector 452 of the LED lamp 401. As described above, the dummy connector 452 is not electrically connected to the LED module 420. For this reason, in this embodiment, the fluorescent lamp power supply unit 220 does not perform any function.

  The translucent cover 231 appears on almost the entire surface below the LED lighting fixture 101, and is made of, for example, a translucent milky white resin that allows light from the LED lamp 401 to pass through while diffusing. In the present embodiment, the translucent cover 231 is provided with an opening through which the lighting fixture mounting apparatus 300 can face. This opening is provided in order to make it easy for the user to perform operations on the lighting fixture mounting apparatus 300 in the work of removing the LED lighting fixture 101.

Then, the fingertip is raised along the operation groove 311, and the operation protrusion 323 of the unit side locking portion 320 is operated by this fingertip. In a normal use state, this opening is covered with a center cap 232. In addition, you may employ | adopt the translucent cover 231 which is not provided with the center cap 232 and opening. In this case, the translucent cover 231 is removed when the LED lighting apparatus 101 is attached and detached.

  Next, operations of the lighting fixture mounting apparatus 300, the LED lighting fixture kit 111, and the LED lighting fixture 101 will be described.

  According to this embodiment, the LED lighting fixture 101 can be comprised by attaching the lighting fixture attachment apparatus 300 and the LED lamp 401 to the conventional lighting fixture for fluorescent lamps. For this reason, it is not necessary to discard all the lighting fixtures for conventional fluorescent lamps, and most of them can be utilized as a part of the LED lighting fixture 101. Therefore, resource saving can be achieved.

  The fact that the pair of locking pieces 321 can be moved in and out and the locking piece 321 has two locking claws 322 and the like are widely used as a conventional lighting fixture mounting tool and the mounting principle. Suitable for common use.

  By disposing the LED lamp power supply unit 330 on the lower side and the unit side locking unit 320 on the upper side, the LED lighting apparatus 101 can be prevented from being unfairly separated from the ceiling 800. By providing the operation groove 311, the operation protrusion 323 can be appropriately operated.

  By configuring the LED lamp 401 with the plurality of straight conductive support members 410, for example, the yield in the manufacturing process can be improved as compared with the case where the arc-shaped conductive support member 410 is used. The straight conductive support member 410 has an advantage that it can be easily loaded into the circular translucent tube 430. The pair of fixing ribs 431 of the translucent tube 430 is suitable for easy and reliable loading of the conduction support member 410. By shifting the LED module 420 with respect to the center of the translucent tube 430, a wider region of the translucent tube 430 can be illuminated when observed from below.

  By providing the dummy connector 452, it is possible to avoid that the fluorescent lamp cable 221 extending from the fluorescent lamp power supply unit 220 hangs down in an unintended posture and blocks light from the LED lamp 401.

  FIG. 8 shows a modification of the LED lamp 401. In this modification, the LED chip 421 is directly mounted on the conduction support member 410. More specifically, the LED chip 421 is bonded to the conduction support member 410 by a bonding material, and is connected to the wiring pattern 414 by a wire. The LED chip 421 is covered with a dome-shaped fluorescent resin 425, for example. The arrangement of the LED chip 421 is the same as that of the LED module 420 in the above-described embodiment.

  According to such a modification, the LED lighting apparatus 101 can be configured while saving resources. In particular, it is possible to reduce the number of components compared to the case where the LED module 420 is used. This is preferable for resource saving.

Further, the translucent tube 430 is fitted into the tube recess 443. In this case, an adhesive may be used as appropriate. The LED lamp 402 is completed by sequentially repeating this assembly.

  FIG. 15 shows the LED lighting apparatus 102 constituted by the LED lighting apparatus kit 112. The difference from the LED lighting apparatus 101 described above is that the dummy connector 452 is not provided. For this reason, the fluorescent lamp connector 222 is not attached to any part. The fluorescent lamp cable 221 is appropriately fixed by, for example, a fixing hook (not shown). Next, in the LED lamp 402, the position of the main connector 451 is different from that of the LED lamp 401. In each LED lamp 402, the main connector 451 is provided in one of the plurality of connectors 440.

  According to such an embodiment, when manufacturing the base material 411 and the translucent tube 430, an intermediate product capable of producing the plurality of base materials 411 and the plurality of translucent tubes 430 is prepared, and these are longitudinally arranged. A plurality of base materials 411 and a plurality of light-transmitting tubes 430 can be obtained by cutting so as to be divided into two. Therefore, the manufacturing efficiency of the LED lamp 402, and hence the LED lighting device kit 112 can be increased.

  The connection angle between adjacent conduction support members 410 and between adjacent light transmission tubes 430 is defined by a connector 440. For this reason, when configuring the LED lamps 402 having different diameters, it is possible to adopt a method in which the conduction support member 410 and the translucent tube 430 have the same specifications and the connection angle by the connection tool 440 is appropriately changed.

  When the cross-sectional shape of the base material 411 is T-shaped, the base material 411 is prevented from rotating or moving with respect to the connector 440. This is preferable for accurately positioning the conductive support member 410 with respect to the connector 440 and finishing the LED lamp 402 to a desired size and shape.

  By providing the cable through-hole 445, the adjacent conduction support members 410 can be appropriately conducted by the connecting cable 419.

  Since the connector 440 is transparent, it is possible to prevent the light from the LED module 420 from being unduly blocked or absorbed by the connector 440. This is preferable for increasing the light quantity of the LED lamp 402.

  FIG. 16 shows another example assembly of the LED lamp 402. In this example, as shown in FIGS. 16 to 19, two conductive fittings 446 are provided on the connector 440. On the other hand, in this example, the cable through-hole 445 is not formed. The conducting metal fitting 446 is exposed on the side facing both the two end surfaces 441 and penetrates the connector 440. The conducting metal fitting 446 is formed, for example, by bending a thin strip member made of metal, and two contact portions 447 are formed at both ends thereof. The contact portion 447 is disposed above the support member recess 444 in the figure, and has a lower end slightly entering the support member recess 444. As shown in FIG. 16, the terminal 414a is arrange | positioned in the electroconductive support member 410 of this embodiment at the longitudinal direction edge part vicinity.

  When the longitudinal end of the conduction support member 410 is inserted into the support member recess 444 of the connector 440, the contact portion 447 of the conduction fitting 446 contacts the terminal 414 a of the conduction support member 410. As a result, the wiring patterns 414 of the conductive support members 410 adjacent to each other with the connector 440 interposed therebetween are electrically connected.

  According to such an embodiment, by attaching the conduction support member 410 to the connector 440, adjacent conduction support members 410 can be appropriately conducted. The abutting portion 447 is formed by bending a thin metal strip member, and can be elastically deformed in the vertical direction in FIG. Thereby, it is possible to bias the elastic force that presses the contact portion 447 against the terminal 414a of the conduction support member 410, and the conduction conduction members 410 adjacent to each other can be more reliably conducted.

  The LED lamp 402 may be configured to directly mount the plurality of LED chips 421 on the conduction support member 410 as shown in FIG. 8 instead of the configuration including the plurality of LED modules 420. Moreover, you may provide the fixing rib 431 shown in FIG.

  The lighting fixture mounting apparatus, the LED lighting fixture kit, and the LED lighting fixture according to the present invention are not limited to the above-described embodiments. The specific configuration of each part of the lighting fixture mounting apparatus, the LED lighting fixture kit, and the LED lighting fixture according to the present invention can be varied in design in various ways.
