Description

[Detailed explanation of the invention] This invention relates to a lighting fixture that is most suitable for use as a temporary work light used for ship sacrifice work and building construction work, and particularly uses fluorescent tubes to reduce power consumption. The present invention also relates to a structure that has a simplified structure and reduced manufacturing costs.

Hereinafter, the lighting equipment of the present invention will be explained based on the embodiment shown in the drawings. Reference numerals 1 and 1' are a pair of upper and lower guards that are used as protection guards for an electric fan, circular mounting plates 2 and 2',
The guard parts 4, 4' are provided with the mounting plates 2, 2' in the center and have a plurality of steel rods 3, 3..., 3', 3'...... arranged radially. And these multiple steel rods 3
, 3..., 3', 3', .
5' 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 top opening 8 and a collar piece 9 extending outward from the periphery of the top opening 8. Inside 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;
Reference numeral 4 denotes a fluorescent tube support spring having two fluorescent tube mounting hooks 15 a and 15 b, and these cover plate 13 and fluorescent tube support spring 14 are secured to the collar piece 9 of the cylindrical case 7 with a screw 16. Fixed.

17 a , 17 b are annular fluorescent tubes, and hook portions 15 a , 15 of a plurality of fluorescent tube support springs 14 , 14 , .
The annular fluorescent tubes 17 a and 17 b are arranged around the cylindrical case 7 coaxially with the cylindrical case 7 by being supported by the fluorescent lamp electrical parts 12 , respectively. They are electrically connected to each other 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 17 a and 17 b from above, and the lower guard 1 The mounting plate 2' of the lower guard 1' is attached to the lower bottom 7 of the cylindrical case 7 so that the surrounding frame 5' of the lower guard 1' covers the cylindrical case 7 and the annular fluorescent tubes 17a and 17b from below.
' is removably tightened with decorative screws 20,
In this state, the upper guard 1 and the lower guard 1' constitute a lamp case in the shape of a flat barrel with their respective front openings facing each other and having concave portions 6 and 6' at the top and bottom, and furthermore, this lamp case Inside, an annular fluorescent tube 17 is placed in a space excluding the portion occupied by the cylindrical case 7 containing the fluorescent lamp electrical parts 12.
a and 17b are provided.

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 top 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 located 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 the fluorescent tubes 17a, 17b are held in a vertical position, that is, by using the upper handle 21 or the side handle 22, the entire luminaire can be hung horizontally or vertically.

Reference numeral 23 denotes a power supply cord with a plug 24 for supplying power to the fluorescent lamp electrical components 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, and in particular includes a pair of upper and lower guards that have a mounting plate at the center of the bottom and an opening at the front, and a cylindrical case that houses fluorescent lamp electrical parts inside. a mounting plate for the upper guard on the upper bottom of the cylindrical case, a mounting plate for the lower guard on the lower bottom of the cylindrical case, and an opening in the upper guard and an opening in the lower guard facing each other. Since the fluorescent tube is installed in the space formed by the upper and lower guards, the upper and lower guards can have the same shape, which reduces manufacturing costs. Furthermore, if the protective guards of an electric fan are used as the upper and lower guards, manufacturing costs can be further reduced and a robust lighting fixture can be obtained.

Furthermore, according to the present invention, the electrical components of the fluorescent lamp are housed in the cylindrical case that connects the pair of upper and lower guards, so that these electrical components do not protrude outward beyond the upper and lower guards. Therefore, it does not take up much space when stored.

In addition, according to this proposal, since the top and bottom of the fluorescent tube are only covered by the top and bottom guards, the light distribution characteristics when turned on are vertically symmetrical, illuminating the entire area around the lighting fixture, and therefore, especially for temporary lighting. When used as a work light, it has the effect of illuminating the entire work area and making it easier to work.
