[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an improvement of a lighting device.
[0002]
[Prior art]
Conventionally, lighting devices used on roads, parks, etc. are generally provided with a socket for mounting a light source inside, and the lower surface of the lighting fixture body is covered with a translucent glove, and one end of the lighting fixture main body is outside. A pole insertion hole is formed on the side surface, and a support portion of the pole is inserted into the pole insertion hole to support the lighting fixture.
[0003]
[Problems to be solved by the invention]
By the way, according to the installation place of a lighting fixture, the structure which inserts the support part of a pole not from the outer surface of a lighting fixture main body but from the lower surface of a lighting fixture is requested | required. However, the above-described conventional lighting device has a drawback that the pole support portions cannot be fitted and supported at desired locations on the outer and lower surfaces of the luminaire body.
There is also a structure in which a pole insertion hole is formed on the lower surface of one end of the luminaire body, and a support portion of the pole is inserted in the pole insertion hole, but according to the structure, it is possible to insert the pole from the outer surface of the luminaire body. Can not.
[0004]
The present invention has been invented in view of the above points, and can support the fitting support portion of the pole from desired locations on the outer surface and the lower surface of the luminaire body, and the luminaire body can be securely and easily mounted on the pole. It is an object of the present invention to provide a lighting device that can be supported by the lighting device.
[0005]
The present invention has the following configuration in order to solve the above problems. In other words, regarding the structure for supporting the lighting fixture on the top of the pole, pole insertion holes are formed on the outer surface and the lower surface in the vicinity of one end of the fixture body. Further, the pole insertion hole cover is pivotally attached to the position where the pole insertion holes on the outer surface and the lower surface of the instrument main body can be shared and covered so as to rotate 90 degrees. The pole is inserted into and supported by one of the pole insertion holes on the outer surface and the lower surface of the instrument body, and the pole insertion hole not covered by the pole is covered with a pole insertion hole cover , and further the pole insertion hole cover. A part of the pole is pressed by a bolt that is screwed into a part of the pole so as to be freely inserted .
[0006]
DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described below with reference to FIGS. In the figure, reference numeral 1 denotes a luminaire main body, which comprises a pole support 2 and a globe support 3 integrally. The luminaire main body 1 is made of aluminum die casting or resin. Reference numeral 4 denotes a rotating shaft formed near one end of the lighting fixture body 1, and 5 denotes an upper cover pivotally attached to the rotating shaft 4, which is configured to open and close with respect to the upper portion of the lighting fixture body 1. is there. The other end of the upper cover is supported by a so-called latch and can be opened and closed.
[0007]
Reference numerals 6 and 7 are pole insertion holes formed in the vicinity of one end of the instrument body, and are formed on the outer surface and the lower surface. 8 is a pole insertion hole cover which is pivotally attached to a position where the pole insertion holes 6 and 7 on the outer surface and the lower surface of the luminaire body 1 can be shared and covered. When the support portion is inserted, the other pole insertion hole is covered. A socket support plate 9 is disposed on a part of the inner wall of the luminaire main body 1 and is arranged in a direction perpendicular to the luminaire main body 1. Reference numeral 10 denotes a socket fixed to the socket support plate 9, and reference numeral 11 denotes a light source attached to the socket, which is configured using, for example, a 220 watt high-pressure sodium lamp. Reference numeral 12 denotes a translucent glove arranged on the lower surface of the luminaire main body 1. Reference numeral 13 denotes a bolt that is screwed into a part of the pole insertion hole cover so as to protrude freely.
[0008]
Next, a specific example of the lighting device will be described. FIG. 2 shows an embodiment in which a pole support portion is inserted into the pole insertion hole 6 on the outer surface of the lighting fixture body 1. In the embodiment shown in FIG. 2, the pole insertion hole 7 on the lower surface is covered with a pole insertion hole cover 8. At this time, a part of the pole 14 is pressed by a bolt 13 that is screwed into a part of the pole insertion hole cover 8 so as to be freely projectable, and the luminaire main body is fixed to the pole.
When the pole support portion is inserted into the pole insertion hole 7 on the lower surface of the luminaire 1, the pole insertion hole cover 8 is rotated 90 degrees as shown in FIG. Is covered with a pole insertion hole cover 8, a pole 14 is inserted through the pole insertion hole 7 on the lower surface, and a part of the pole is pressed with a bolt that is screwed into a part of the pole insertion hole cover so as to be freely inserted. , Fix the luminaire body to the pole.
[0009]
【The invention's effect】
According to the present invention described above, the pole support portion can be fitted and supported from desired locations on the outer and lower surfaces of the luminaire body, and the luminaire body can be reliably and easily supported on the pole. effective.
