Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an improvement in a retractable lighting device used at a golf course.

[Conventional technology and its problems] In recent years, at Corfu course, lighting lights have been installed along the greens of each course to allow night play.
Also, if the sun sets during play, play will have to be stopped, so lights are installed on the first few holes.

By the way, at golf courses, lighting lights are supported on the tops of poles about 14 meters high, which destroys nature and spoils the scenery during the day.

Therefore, it may be possible to maintain the scenery by lowering the illuminating lights to the shade of trees during the day and raising them to a predetermined height when the illuminating lights are used.

However, the number of lighting lights used at a golf course is, for example, 1000.
It is necessary to arrange, for example, a set of 6 to 8 floodlights each containing high-pressure metal vapor discharge lamps in the middle hall. If a set of 6 floodlights is used, the weight will be about 140 kg including the stand, so it will be able to withstand that weight, and the height will be 13 kg.
Since the weight is approximately 1.5 meters and wind pressure is also applied, equipment that can withstand the weight and wind pressure is required.

It should be noted that the simple telescoping lighting devices conventionally attached to moving vehicles and used as night lights have weak mechanical strength and are of no use.

[Purpose of the invention] The present invention was devised in view of the above points, and is a device that firmly supports a lighting lamp with a relatively simple device.
When the lights are not in use during the day, lower them.
To provide a retractable lighting device which raises a lighting lamp at night or at sunset and does not spoil the view of a golf course during the day.

[Means for Solving the Problems] The present invention will be explained below with reference to FIGS. 1 to 7. In the figure, reference numeral 1 denotes a box-shaped base body, which has an appropriate number of air circulation holes 2 at appropriate positions on the side wall. Reference numeral 3 denotes a pedestal having a hole 4 in the center and provided on the upper surface of the base 1. For example, the pedestal 3 has a plurality of truncated conical shapes, has an inclined surface 5 facing downward at the outer end, and has an outer periphery at the lower end. It is constructed by having several cable receiving parts 6 at the top. Reference numeral 7 denotes a frame supported inside the base body 1, and is configured to support a support column by disposing a plurality of frames at predetermined intervals or by making a hole in the center of a flat plate. Reference numeral 8 denotes a telescope-shaped support made of a plurality of tubes having different diameters, and is extendable and retractable, and the outer end support 9 is supported on a frame.
Reference numeral 10 denotes a support arm supported by a column 11 at the inner end, and is configured in a frame shape. Reference numeral 12 denotes illumination lamps supported by the support arm 10, and is configured as a set of six projecting lamps, for example. For example, a 1000 watt high pressure metal vapor discharge lamp is housed inside the floodlight fixture. 22 is the fourth
As shown in the figure, it is a flexible coil with one end connected to the lower end of the inner support column 11, and is housed in a coil shape inside a casing 24 provided inside the base body 1, so that the support column 8 can be expanded and contracted. It is configured to move up and down in accordance with the movement. 13 is a flexible coil 2 as shown in FIG.
The gear 13 is a gear for moving the flexible coil 22 up and down, and the protrusion 15 of the gear 13 engages with the groove 14 of the flexible coil 22 to move the flexible coil up and down. 16 is a motor for rotating the gear 13;
Reference numeral 17 denotes a cable whose upper end is connected to the illumination lamp 12, which is wound several times at intervals on the outside of the support 8, and as the support 8 lowers, it is wound along the slope of the frame 3. It is configured to be coiled and supported. 18 is a ballast for lighting the metal vapor discharge lamp; 19 is a terminal for remote control equipment for moving the column 8 up and down; 20 is a terminal box for connecting power lines, etc.; 21 is a terminal for connecting the column 8; This is a safety device when moving up and down. The stabilizer 18, a terminal device 19 for remote control equipment, a terminal box 20, and a safety device 21 are all housed and supported inside the base body 1.

[Operation of the invention] Next, the operation when the retractable lighting device having the above-mentioned configuration is installed at a golf course, for example, will be explained.

A. For daytime use, (1) A set of six floodlight fixtures each consisting of a 1000 watt high-pressure metal vapor discharge lamp housed inside the floodlight fixtures is supported on the top of the support column 8, for example. A set of six lights is set at the middle hole, and the three uphill holes are illuminated by a tracking light source to track the trajectory, as shown in FIG.

(2) Also, during the day, the telescopic column 8 supporting the illumination light 12 is configured to be the shortest, and the illumination light 12 is covered with leaves to maintain the scenery of the golf course.

B Regarding sunset and nighttime (1) Lighting lamp 12 that was lowered during the day and was in the shade of a tree
is raised to a predetermined height from sunset to night, and golf is played from sunset to night under a predetermined illuminance.

(2) To raise the illumination lamp 12, activate the terminal 19 of the remote control device, rotate the motor 16, and push up the flexible coil 22, thereby raising the columns 8 one after another.

(3) Furthermore, the illumination light 12 is configured to rise up to a maximum of about 14 meters, for example.

When the lighting lamp is lowered after playing golf, the flexible coil is stored in a coiled form inside the casing at the inner bottom of the base, and the cable is coiled and supported along the sloped surface of the upper part of the frame. be done.

[Effects of the invention] As described above, the present invention has a structure in which a column supporting a lighting lamp is supported by a frame inside the base, and electrical and mechanical devices such as ballasts and terminals for remote control equipment are supported. Since the lamp is housed and supported, the lighting lamp can be supported reliably and firmly, and the device is relatively simple.

Furthermore, the flexible coil that moves the lighting lamp up and down is stored in a coil shape at the inner bottom of the base, and the cable is wound multiple times at intervals on the outside of the column, so it has a coiling habit. Since the cable is easily coiled and supported on the upper part of the pedestal along the inclined surface, the device for raising and lowering the lighting lamp and the device for winding the cable can be constructed relatively easily.

In addition, as mentioned above, the lighting lights go down during the day and go behind the trees, and go up at sunset and when they are used at night, so during the day the lighting lights do not spoil the view of the golf course. It has various advantages such as:
