Description

[Detailed explanation of the invention] This invention relates to lighting equipment that is optimal for use as temporary work lights used in ship wrapping work and building construction work, and in particular uses fluorescent tubes to reduce power consumption. The present invention relates to a lighting device that is constructed so that it can be hung either horizontally or vertically, thereby expanding its range of use.

Hereinafter, the lighting equipment of the present invention will be explained based on the embodiment shown in the drawings. 1.1' is a pair of upper and lower guards that are used as protective guards for an electric fan, circular mounting plates 2, 2',
The mounting plates 2, 2' are provided in the center and a plurality of steel rods 3, 3...3/. 3/ Guard parts 4, 4' arranged radially, and these plurality of steel rods 3,
A surrounding frame 5 connecting the open ends of 3..., 3/, 3/... and forming a front opening of the guard parts 4', 4';
5', it has recesses 6, 6' at the center of the bottom, and the mounting plates 2, 2' are positioned in the recesses 6, 6'.

Reference numeral 7 denotes a metal cylindrical case having a collar piece 9 extending outward from the periphery of the upper surface opening 8 at the upper surface frontage 8, and within this cylindrical case 7 are two stabilizers 10 and 10'. and a fluorescent lamp electrical component 12, such as a glow lamp 11, 11',
The center of gravity of all of them is fixed so as to be located in the center of this cylindrical case 7.

13 is a cover plate that covers the upper opening 8 of the cylindrical case 7;
4 is a fluorescent tube support spring having two fluorescent tube mounting hooks 15a and 15b;
4 is fixed to the flange piece 9 of the cylindrical case 7 with screws 16.

17 a , 17 b are annular fluorescent tubes, and hook portions 15 a , 15 of a plurality of fluorescent tube support springs 14 , 14 , .
These annular fluorescent tubes 17 a and 17 b are disposed coaxially around the cylindrical case 7 by being supported at points b, respectively, and these annular fluorescent tubes 17 a and 17 b are connected to the fluorescent lamp electrical component 12 . They are electrically connected using fluorescent lamp sockets H8a and 18b.

The surrounding frame 5 of the upper guard 1 is connected to the cylindrical case 7.
The mounting plate 2 of the upper guard 1 is fixed to the lid plate 13 serving as the upper bottom of the cylindrical case 7 with screws 19 so as to cover the annular fluorescent tubes 17a and 17b from above, and the mounting plate 2 of the lower guard 1' A mounting plate 2' of the lower guard 1' is attached to the lower bottom 7' of the cylindrical case 7 with decorative screws 20 so that the surrounding frame 5' covers the cylindrical case 7 and the annular fluorescent tubes 17a and 17b from below. The upper guard 1 and the lower guard 1' are removably tightened and fixed, and in this state, the upper guard 1 and the lower guard 1' have a flat barrel shape with their respective front openings facing each other, and a lamp case having upper and lower concave portions 6, 6'. Furthermore, inside this lamp case,
Annular fluorescent tubes 17a and 17b are disposed in a space excluding the portion occupied by the cylindrical case 7 in which the fluorescent lamp electric component 12 is housed.

Reference numeral 21 denotes an upper handle rotatably supported in the recessed part 6 of the upper guard 1, and when the upper handle 21 is used, the recessed part 6
It protrudes from the wall and is folded and stored in the recess 6 when not in use.

Reference numeral 22 denotes a side handle rotatably supported by the peripheral frame 5 of the upper guard 1, and is positioned exactly at the engagement portion between the upper guard 1 and the lower guard 1'.

Since the center of gravity of the cylindrical case 7 is located in the middle of the cylindrical case 7, the fluorescent tubes 17a and 17b are held horizontally when the upper handle 21 is used, and when the side handle 22 is used. Sometimes fluorescent tubes 17a, 17b
is held in a vertical position, that is, by using these upper handles 21 or side handles 22, the entire lighting device can be hung horizontally or vertically.

Incidentally, this side handle 22 may be rotatably supported on the peripheral frame 5' of the lower guard 1' instead of the peripheral frame 5 of the upper guard 1.

Reference numeral 23 denotes a power supply cord with a plug 24 for supplying power to the fluorescent lamp electric component 12 housed in the cylindrical case 7, and one end of the cord is connected from the mounting plate 2 of the concave portion 6 of the upper guard 1 to the cover plate 1.
3 into the cylindrical case 7, and the power supply cord 23 is housed in the concave portion 6 when the lighting device is not in use.

The present invention is constructed as described above, in particular, a pair of upper and lower guards each having a concave portion at the center of the bottom and a surrounding frame provided at the front opening, and a pair of upper and lower guards interposed between the upper and lower guards. In addition, a cylindrical case housing electrical parts of a fluorescent lamp such as a ballast, a fluorescent tube disposed in a space formed by the upper guard and the lower guard, and a rotatable case mounted in a recessed part of the upper guard. It consists of an upper handle that is pivoted, and a side handle that is rotatably pivoted on the surrounding frame of the upper or lower guard, so just by hanging this upper handle, the entire lighting fixture can be placed in a horizontal position. Since the upper and lower parts of the fluorescent tube are simply covered with upper and lower guards of approximately the same shape, the light distribution characteristics in the upper and lower directions are the same.
Therefore, the ceiling and floor can be illuminated simultaneously, while the entire lighting fixture can be kept in a vertical position simply by hanging the side handles. It has the effect of being easily hung even in a narrow space, and when used especially as a temporary work light, it can illuminate the entire work area with low power consumption and can be installed anywhere. .
