BEST MODE FOR CARRYING OUT THE INVENTION A first embodiment of the present invention will be described with reference to FIGS. That is, this lighting fixture has a base 1, a pair of columns 2, a universal device 3, and a lamp 4. The base 1 has a built-in lighting circuit (not shown),
A touch switch 5 for blinking is provided on the surface, and a power supply line 6 connected to an outlet or the like is drawn outside.

The pair of support columns 2 are substantially parallel to each other and are erected on the base 1. Each of these columns 2 uses a column material having a square cross section. The universal device 3 is installed on the upper ends of the columns 2. This universal device 3 is a rotary type. The lamp 4 is a universal device 3 that can enter between the pair of columns 2.
It is attached to and rotates. In the embodiment, the instrument main body 7 is fixed to the gate post-shaped portion formed by the support column 2 and the universal device 3. In addition, the lamp 4 includes a pair of columns 2 as shown in FIG.
180 degrees from the position where it entered between
The range of degrees can be rotated.

Reference numeral 8 is a lamp socket, and 9 is a lamp.
According to this embodiment, since the pillar 2 and the universal device 3 are formed in a gate pillar shape, and the lamp fitting 4 that can enter the inside of the gate pillar shape is attached to the universal device 3, it is possible to enter between the pillars 2. The lamp 4 can be rotated and can be used as direct light and diffused light.

A second embodiment of the present invention is shown in FIGS. That is, in this lighting device, in the first embodiment, the lighting device body 7 is a lighting device 7 ′ divided from the lighting device 4, and the lighting device 7 ′ is also attached to the universal device 3 and is separated from the lighting device 4. It is possible to rotate. Moreover, the lamp 4 is made of a non-translucent material, and the lamp socket 8 and the lamp 9 are built in so that the lamp light A is emitted from the opening 4a. However, the lamp 7'is made of a translucent material. When the opening 4a is housed in the lamp 7 ', it serves as a shade for emitting diffused light B.

FIG. 5 shows a state in which the lamp 4 is opened and the opening 4
a is directed downward, and the lamp light A directly irradiates the floor surface or the desk surface. FIG. 6 shows a state in which the opening 4a of the lamp 4 is applied to the lamp 7'and the opening 4a is closed. At this time, light is transmitted from the lamp 7 ', diffused light B is emitted, and the floor surface or the like is laterally irradiated. To do. In FIG. 7, the lamp 7'is in an open state, and the lamp light A of the lamp 4 directly goes out to the right side.

According to this embodiment, it can be used in a wide range of applications as direct light and diffused light. Others are the same as in the first embodiment. A third embodiment of the present invention is shown in FIG. That is, this luminaire
In the second embodiment, the lamp fixture 7'is configured to include the lamp socket 8'and the lamp 9 '. In this case, both the lamps 4 and 7'may be translucent or non-translucent.

Note that one of the lamps 4 and 7'may be fixed. A fourth embodiment of the present invention is shown in FIG. That is, in this lighting fixture, in the first embodiment, the fixture main body 7 is removed, and the lighting fixture 4 is installed between the pair of support columns 2, that is, the inside of the substantially gate pillar shape formed by the pair of support columns 2 and the universal device 3. The lamp 4 can be passed through and the lamp 4 can be rotated 360 degrees. In addition, in the posture of FIG. 9 in which the lamp 4 is horizontal, the opening 4a is directed downward and the lamp light A is controlled downward.

FIG. 10 shows a state in which the lamp 4 is rotated in the counterclockwise direction by 90 degrees from the state in which it is located inside the column 2, and is horizontally rotated rightward. FIG. 11 is further rotated in the counterclockwise direction by 90 degrees. The state of being rotated vertically is 90 ° in the counterclockwise direction in FIG.
It is in a state in which it is rotated to a horizontal posture. According to this embodiment, since the lamp 4 can rotate around the universal device 3, various light distributions can be obtained. Others are the same as in the first embodiment.

[0016]

According to the luminaire of the first aspect, since the pillar and the universal device are formed in a gate pillar shape, and the lamp fitting that can enter the inside of the gate pillar shape is attached to the universal device, it enters between the pillars. Thus, there is an effect that the lamp can be rotated and can be used as direct light and diffused light.

According to the lighting equipment of claim 2, in the lighting device of claim 1, the lamp is divided into two parts, so that the lighting device can be used for a wide range of purposes as direct light and diffused light in addition to the effect of claim 1.
