The light emitting part mounting member 3 is rotated in the circumferential direction around the vertical axis of the lighting fixture 1 so as to slide with the peripheral edge 4F of 4B as a guide surface. In this case, the screw member 18 moves in the circumferential direction while entering the arcuate guide hole 16.

  By this operation, the light emitting portion mounting member 3 is lowered while the leg portion 34 corresponds to the new positioning hole 15. As a result, the leg portion 34 is fitted into the new positioning hole 15, and the screw member 18 is rotated in this state, and the light emitting portion 6 is irradiated with new light while the nut member 19 is in contact with the lower surface of the support plate portion 4B. The light emitting unit mounting member 3 is fixed to a predetermined position of the support member 4 at the directional position.

As described above, by changing the position of the light emitting unit mounting member 3 with respect to the support member 4, the irradiation directions of the four light emitting units 6 can be individually changed with respect to the vertical axis of the lighting fixture 1. Become.
In this way, by individually changing the irradiation direction of the light emitting unit 6, it is possible to obtain illumination with reduced glare (glare) as much as possible for neighboring residents and pedestrians. One example thereof is FIG. 13, and FIG. 13 is a plan view showing a state in which the light-emitting units 6 are arranged in one direction. It can be arranged so as not to directly illuminate the direction in which glare (glare) is felt (the left side in FIG. 13 and the direction of the back side of the light emitting unit 6).

  FIG. 13 shows a state in which the four light emitting units 6 are arranged in one direction. For example, the light emitting unit 6 on the side that reduces glare in the state of FIG. 8 (for example, FIG. 8). It is also possible to remove the upper light emitting part 6), or remove two of the four light emitting parts 6 in FIG. 13 on both the left and right sides, and use the remaining two for unidirectional illumination.

  In addition, as shown in FIG. 13, when the lamp is arranged in one direction, the illuminance by the light emitting unit 6 in the one direction increases compared to the case in FIG. Effective when required.

In such an operation of changing the light irradiation direction of the light emitting unit 6, the screw member 18 moves along the arcuate guide hole 16 while being inserted into the arcuate guide hole 16. When a plurality of arc-shaped guide holes 16 are formed on one circumference, for example, the arc-shaped guide holes 16 are arranged at four equal positions on the upper side, the arc-shaped guide holes 16 are arranged between the arc-shaped guide holes 16 as shown in the figure. There is a discontinuous portion 20 where the arcuate guide hole 16 does not exist.
For this reason, when moving the screw member 18 to the adjacent arcuate guide hole 16 across the discontinuous portion 20, the screw member 18 is once removed from the nut member 19 and moved to the adjacent arcuate guide hole 16. It is necessary to screw the screw member 18 to the nut member 19 again at a stage, and in this case, the nut member 19 that has been detached from the screw member 18 is dropped if not held by hand.

In order to prevent this, as shown in FIGS. 11 and 12, the nut member 19 passes through the longitudinal long hole 33 </ b> A formed in the guide portion 33 and is located below the support plate portion 4 </ b> B and is located on the screw member 18. And a locking portion 19B connected to the nut 19A and locking to the edge of the hole 33A of the guide portion 33.
The nut member 19 is heavier in the nut portion 19A than the locking portion 19B. As a result, as shown by dotted lines in FIGS. 11 and 12, the nut member 19 is engaged with the edge portion of the hole 33A of the guide portion 33 in the state in which the screw engagement with the screw member 18 is released. It becomes a suspended state in the stopped state.
For this reason, even when the screw member 18 is moved from one arcuate guide hole 16 to the adjacent arcuate guide hole 16, there is no possibility of dropping without holding the nut member 19 detached from the screw member 18 by hand. The nut member 19 is not lost, and the operation of changing the light irradiation direction of the light emitting unit 6 can be performed efficiently.

The translucent cover member 5 is made of glass or synthetic resin that transmits light emitted from the light emitting unit 6, and is milky white or has a textured surface on the inner surface so that each component housed inside is difficult to see from the outside. Processing is applied.
The translucent cover member 5 has a spherical circumferential surface shape that expands from the lower part to the upper part in order to transmit and diffuse the light emitted from the light emitting unit 6, and has circular openings 5 </ b> A and 5 </ b> B at the upper part and the lower part. An inward annular flange 5C formed on the peripheral edge of the lower opening 5B is placed on the cover attachment portion 2C of the attachment base 2 via the annular packing 21, and the metal fixture 22 is placed on the annular flange 5C.
