  Hereinafter, a lighting apparatus according to an embodiment of the present invention will be described with reference to the drawings by taking a downlight as an example.

  As shown in FIG. 1, a lighting fixture 10 according to an embodiment of the present invention includes an arm 11, a socket 12 attached to the arm 11, a reflector 16 fixed to the arm 11 with screws, and a terminal block 14. And is attached to a mounting hole 2 formed in a ceiling surface 1 of a house or the like.

  The arm 11 has a terminal block 14 assembled on the side thereof, and the terminal block 14 is electrically connected to the socket 12 through the instrument wiring 15.

  The arm 11 has a reflecting plate 16 formed at the center. The reflecting plate 16 is formed in a spherical shape with the floor side, which is the lower side in FIG. The arm 11 has a flange-shaped frame member 17 at its lower end.

  The arm 11 is assembled by inclining the socket 12 with respect to the horizontal plane A1 by a predetermined angle α1.

  A lighting unit 13 is fitted in the socket 12. The lighting unit 13 integrally includes a mounting portion 18, a power source portion 19, and a lighting portion 20.

  As shown in FIG. 2, the lighting unit 20 includes a plurality of, for example, six LEDs (light emitting diodes) 21, and five of them are arranged radially around the central one.

  As shown in FIG. 3, the attachment portion 18 is molded using a resin material having a slight flexibility, and is used to obtain a commercial power source (see FIG. 4) AC. The power source unit 19 adjusts electricity obtained from the commercial power source AC by converting it into a direct current. The lighting unit 20 lights the LED 21 with a direct current supplied from the power supply unit 19.

The power supply unit 19 is assembled so as to be separable from the lighting unit 20. Therefore, the lighting unit 20 can be connected to the power source unit 19 by appropriately changing the lighting unit 20 having different specifications such as the brightness, light color, and light distribution of the LED 21.
Therefore, the lighting fixture 10 can easily coordinate light by appropriately changing optical characteristics such as brightness, light color, and light distribution.

Since the power supply unit 19 and the lighting unit 20 are separable, the power supply unit 19 can be attached to the socket 12 first, and then the lighting unit 20 can be connected to the power supply unit 19.
Therefore, the lighting fixture 10 can reliably connect the lighting unit 20 without interfering with the reflecting plate 16 in the arm 11.

The lighting unit 20 has an irradiation direction directed downward in FIG. The irradiation direction of the lighting part 20 and the fitting direction of the attachment part 18 to the socket 12 have a predetermined angle α2. The angle α2 can be arbitrarily changed.
Therefore, the lighting fixture 10 can perform the effect of the light by the irradiation direction of the lighting part 20 by changing the irradiation direction of the lighting part 20 with respect to the fitting direction to the socket 12 of the attachment part 18 to arbitrary directions. .

  As shown also in FIG. 4, the socket 12 has a pair of terminals 22 and 23. The power supply unit 19 has a pair of terminals 24 and 25 that are electrical connection portions on the socket 12 side of the mounting portion 18 and a pair of terminals 26 and 27 on the lighting portion 20 side. The lighting unit 20 has a pair of terminals 28 and 29 on the power supply unit 19 side.

  The terminals 28 and 29 of the lighting unit 20 are electrically connected to the terminals 26 and 27 of the power supply unit 19 by connecting the lighting unit 20 to the power supply unit 19, respectively.

  The terminals 24 and 25 of the power supply unit 19 are electrically connected to the terminals 22 and 23 in the socket 12 by fitting the lighting unit 13 to the socket 12 and are connected to the commercial power supply AC.

  As shown in FIG. 5A, the attachment portion 18 includes a shaft portion 30, a cylindrical portion 31, and a pair of flexible portions 32.

  The shaft portion 30 is formed in a shaft shape that is inserted into the socket 12. The shaft portion 30 accommodates one of the pair of terminals 24 and 25 of the power source portion 19. The terminal 24 protrudes from the shaft portion 30 at the tip.

  The cylindrical portion 31 is formed in a cylindrical shape outside the shaft portion 30, and has an outer diameter slightly smaller than the inner diameter of the socket 12.

  The flexible portions 32 are notched from the cylindrical portion 31 at positions facing the cylindrical portion 31, and are flexible toward the shaft portion 30.

  The other terminal 25 of the pair of terminals 24, 25 of the power supply unit 19 is attached to the outer periphery of the flexible part 32. The other terminal 25 has a concave and convex engaging projection 33 constituting one of the locking means on the outer peripheral portion of each tip.

  As shown in FIG. 5B, the socket 12 includes a peripheral plate 34 and a bottom plate 35. The pair of terminals 22 and 23 in the socket 12 are assembled to the bottom plate 35.

  The other terminal 23 of the pair of terminals 22 and 23 in the socket 12 is disposed on the inner periphery of the peripheral plate 34. The other terminal 23 forms a concave and convex engaging projection receiving portion 36 constituting the other of the locking means on the outer peripheral portion of each tip portion.

  When the mounting unit 18 is inserted into the socket 12, the lighting unit 13 is configured so that the flexible portion 32 is in sliding contact with the inner surface of the peripheral plate 34 of the socket 12 to reduce the outer diameter toward the shaft portion 30. It advances into the socket 12 while being elastically deformed.

  As shown in FIG. 5C, thereafter, one terminal 24 of the shaft portion 30 is electrically connected to one terminal 22 of the bottom plate 35 of the socket 12.

  At the same time, since the flexible portion 32 accumulates an elastic repulsive force, the flexible portion 32 is elastically restored to increase the outer diameter. As a result, the engaging protrusion 33 of the other terminal 25 of the flexible portion 32 is engaged with the engaging protrusion receiving portion 36 of the other terminal 23 by the elastic restoring force, and is held in a locked state. 25 is electrically connected to the other terminal 23.

  In this manner, the lighting unit 13 is electrically connected to the terminals 24, 22, 25, and 23 by a simple operation in which the attachment portion 18 is inserted into the socket 12 without being screwed.

  Next, the assembly procedure of the lighting fixture 10 will be described.

  As shown in FIG. 6A, first, the power supply unit 19 and the lighting unit 20 of the lighting unit 13 are separated. Here, for example, in a shop or the like, it is desirable to prepare a lighting unit 20 having a plurality of specifications and sell the lighting unit 20 and the power source unit 19 selected by the user as a set.

  As shown in FIG. 6B, the power supply unit 19 is advanced toward the socket 12 with only the power supply unit 19, and only the power supply unit 19 is attached to the socket 12.

  The power supply unit 19 is electrically connected to the terminals 24, 22 and 25, 23 when the mounting unit 18 is inserted into the socket 12.

  Next, as illustrated in FIG. 6C, the lighting unit 20 is connected to the power supply unit 19. The lighting unit 20 proceeds from the lower side in FIG. 6C toward the power source unit 19.

  As shown in FIG. 6D, the terminals 28 and 29 of the lighting unit 20 are electrically connected to the terminals 26 and 27 of the power source unit 19 by connecting the lighting unit 20 to the power source unit 19, respectively.

In the lighting fixture 10 of one embodiment of the present invention, the lighting unit 13 is attached to the arm 11 by fitting into the socket 12.
Thereby, since the lighting unit 13 can be mounted on the conventional socket 12 as it is, it is not necessary to process the arm 11 and can be easily applied to an alternative light source.
Therefore, the replacement workability can be improved by mounting the socket 12 very simply.

In the lighting fixture 10 of one embodiment of the present invention, the lighting unit 13 is attached to the arm 11 by being inserted into the socket 12 or the like.
Therefore, unlike the conventional one, there is no need to screw the LED bulb into the socket to make an electrical connection, and the optical axis selection of the LED 21 is not affected by the screwing.

In the lighting fixture 10 of one Embodiment of this invention, the irradiation direction of the lighting part 20 can be changed into arbitrary directions with respect to the fitting direction to the socket 12 of the attaching part 18. FIG.
Therefore, by changing the irradiation direction of the lighting unit 20 with respect to the fitting direction of the mounting unit 18 to the socket 12 to an arbitrary direction, it is possible to produce light in the irradiation direction of the lighting unit 20.

In the lighting fixture 10 of one Embodiment of this invention, the structure of the lighting part 20 can be changed arbitrarily and can be couple | bonded with the power supply part 19. FIG.
Therefore, it is possible to easily coordinate light by changing optical characteristics such as brightness, light color, and light distribution.

In the lighting fixture 10 of one embodiment of the present invention, the lighting unit 20 can be removed from the power supply unit 19, the power supply unit 19 can be attached to the socket 12, and then the lighting unit 20 can be connected to the power supply unit 19.
Therefore, the lighting unit 20 can be reliably connected without interfering with the reflecting plate 16 in the arm 11.

In the lighting fixture 10 according to the embodiment of the present invention, the lighting unit 13 is configured such that the terminals 24 and 25 are electrically connected to the terminals 22 and 23 of the socket 12 by fitting the mounting portion 18 to the socket 12. At this time, the lighting unit 13 is held in a state where it is mounted on the socket 12 by locking the engaging protrusions 33 provided on the terminals 24 and 25 and the engaging protrusion receiving parts 36 provided on the terminals 22 and 23.
Therefore, the lighting unit 13 can reliably form an energization circuit without being easily dropped when the lighting unit 13 is mounted on the socket 12.

  In addition, the arm 11, the socket 12, the reflecting plate 16, the frame member 17 and the like used in each of the embodiments are not limited to those illustrated, and can be appropriately changed.
