Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is particularly useful for waterproofing when both ends of a tubular globe in which a straight tubular fluorescent lamp is inserted are fitted into left and right socket boxes. The present invention relates to a fluorescent lamp luminaire that allows safe and easy replacement of fluorescent lamps in lighting equipment.

[Prior Art] When replacing a fluorescent lamp in a lighting fixture in which both ends of a tubular globe into which a straight tubular fluorescent lamp is inserted are fitted in left and right socket boxes, conventionally, the tubular globe is removed together with the fluorescent lamp. In addition to replacing the socket, there was one that opened the outside of one socket box to remove the socket, and then inserted and removed the fluorescent lamp in the axial direction.

[Problems to be solved by the invention] In a case where the tubular globe is removed together with the fluorescent lamp and the fluorescent lamp is replaced, the tubular globe and the fluorescent lamp must be installed and removed at the same time. Since the globe and the fluorescent lamp are about the same length, only the end of the fluorescent lamp can be directly operated during installation and removal work. Long length of 40 W or more, which is frequently used. It was difficult to replace the fluorescent lamp of (1) when one person worked, because both ends were out of reach and the work was mainly at high places.

That is, since the tubular globe and the fluorescent lamp must be attached and detached at the same time, and the fluorescent lamp must be secured by only one end, there is a high risk that the fluorescent lamp will be dropped and damaged. However, since the middle part of the fluorescent lamp cannot be touched, only one end of the fluorescent lamp must be operated to move the other end vertically and horizontally to fit into the socket.

In the case of inserting and removing the fluorescent lamp in the axial direction, such a problem can be solved, but when installing multiple lighting fixtures in series or when there is not enough space on both sides of the lighting fixture installation location. Had a problem that it took a lot of time and labor to remove the fluorescent lamp and to disassemble it.

The present invention solves the above-mentioned problems, and fluorescent lamps are particularly useful for waterproofing where both ends of a tubular globe with a straight tubular fluorescent lamp inserted are fitted into the left and right socket boxes. It is an object of the present invention to provide a fluorescent lamp luminaire in which lamp replacement can be performed safely and easily.

[Means for Solving the Problems] To explain the configuration of the present invention for achieving the above object,
According to the present invention, the cylindrical globe (2) into which the straight tubular fluorescent lamp (1) is inserted has the left and right socket boxes (3) and (3) respectively.
In the lighting fixture to be fitted to, one of the sockets is a movable socket (4) that can be moved left and right and fixed, and the other socket is a fixed socket (5). Left and right socket boxes (3) and (3) at both ends of the glove (2)
Straight tube fluorescent lamp inserted at the fitting position
(1) A fluorescent lamp lighting fixture, characterized in that a holding member (6) capable of elastically inserting and holding the fluorescent lamp (1) is provided so that one end thereof is almost guided to the fixed socket (5). Pertain.

In this case, the fixed socket (5) does not depart from the gist of the present invention even when the movable socket is used in a fixed state, and the movable socket (4) includes not only the socket but also the socket. Even if the entire socket boxes (3) and (3) can be fixed to the left and right, it does not depart from the gist of the present invention.

In addition, the provision of the holding member (6) only at one end of the tubular globe (2) means that nothing is provided inside the other portion of the tubular globe (2), or if it is provided, it does not affect the fluorescent lamp (1). ) Is not restricted to one place.

[Operation] When removing the fluorescent lamp (1), the moving socket (4) is moved to the outside, one end of the fluorescent lamp (1) is removed from the moving socket (4), and then the one end is grasped and the fluorescent lamp is grasped. The other end is removed from the fixed socket (5) by shifting (1) in the same direction, and the fluorescent lamp (1) together with the tubular globe (2) is held by the holding member (6) as shown in FIG. Remove. After that, in a safe place, from the tubular globe (2) to the fluorescent lamp (1)
Get rid of.

When installing the fluorescent lamp (1), first insert the fluorescent lamp (1) into the cylindrical globe (2) in a safe place, and as shown in FIG. 4, hold one end of the fluorescent lamp (1) at a holding member ( Insert and hold in 6). By inserting the holding member (6) into the cylindrical globe (2) from the side where the holding member (6) is provided, the work can be performed very easily.

Then, while the fluorescent lamp (1) is held by the holding member (6), the holding member (6) side is made to correspond to the fixed socket (5), and the tubular globe (2) is attached to the left and right socket boxes (3). (3) Place it in the fitting position. Then, one end of the inserted straight tubular fluorescent lamp (1) is almost guided to the fixed socket (5).
It is possible to easily fit the other end into the fixed socket (5) by operating only the end of the fluorescent lamp (1) on the side of the moving socket (4) without operating the middle part of (1). You can

Since the holding member (6) can elastically insert and hold the fluorescent lamp (1), the holding member (6) can be adapted to the size of the fluorescent lamp (1).

Further, since the holding member (6) is provided only at one end of the cylindrical globe (2), the fluorescent lamp (1) is conical or pyramidal with the holding portion by the holding member (6) as the center. It is possible to reduce the influence of whether the fitting of the fluorescent lamp (1) is appropriate or not due to the size of the fluorescent lamp (1) and the dimensional error between products.

[Embodiment] A drawing showing an embodiment of the present invention will be described. Reference numeral (7) is a substrate, and (8) is a socket cover, which together form a socket box (3).

The moving socket (4) is connected to the board through the socket support plate (9).
(7) A screw (10) is screwed on the top so that it can move left and right.

(11) is a glow ball and (12) is a glow ball socket. The glow ball socket (12) is preferably provided on the moving socket (4) side in order to facilitate replacement work.

(13) is a waterproof packing, and the board (7), the socket cover (8) and the tubular globe (2) are the waterproof packing.
It is fitted in a waterproof state through (13).

The holding member (6) is provided with an overhanging plate (14) having a circular hole inward at one end of the cylindrical globe (2), and an elastic plate is formed so that the fluorescent lamp (1) can be inserted thereinto substantially U. It is formed in a letter shape and has a notch and is engaged and fixed in the circular hole of the overhanging plate (14) .In order to facilitate the insertion of the fluorescent lamp (1), the outer peripheral edge is expanded outward. Is provided with a plurality of guide pieces (6a) and (6a). Guide piece
(6a) and (6a) are one on the left and one on the right in the drawing, but two on each side.
It may be provided as necessary, such as by providing the above.

(15) is a base in which a ballast and the like are built-in, and the base cover (16) is a base body (18) without using screws by the locking members (17) and (17) at both ends. ).

To remove the fluorescent lamp (1), the left and right socket covers (8)
Remove (8), loosen the screw (10), move the moving socket (4) to the outside, slide the fluorescent lamp (1) in the same direction to remove it from the fixed socket (5), and remove the tubular globe (2) together. Remove. Installation is the opposite.

[Effect of Invention] Next, the effect of the present invention will be described.

(a) Installing and removing the fluorescent lamp from the socket and socket box, which are often performed in high places, is done with the tubular globe while the fluorescent lamp is held by the holding member. Removal of the fluorescent lamp can be done in another safe place.

Therefore, in the conventional installation and removal work, the end of the fluorescent lamp, especially when one person replaces a long fluorescent lamp that is frequently used, had to be secured by grasping only one end. However, it is possible to work extremely easily and surely.

Further, even if a plurality of lighting fixtures are connected in series, or if they are attached to places where there is no space on the left and right, it is possible to easily work.

(b) When mounting, with the fluorescent lamp held by the holding member, place the tubular globe at the left and right socket box fitting positions with the holding member side corresponding to the fixed socket, and insert the straight tubular fluorescent light. Since the end of the lamp 1 is almost guided to the fixed socket, the other end can be easily fitted into the fixed socket by operating only the end of the fluorescent lamp on the side of the moving socket without operating the middle part of the fluorescent lamp. Can be combined.

Therefore, the work becomes extremely efficient as compared with the case where only one end of the fluorescent lamp is conventionally operated and the other end is moved vertically and horizontally to be fitted in the socket.

(c) Since the holding member is capable of elastically inserting and holding the fluorescent lamp, it is possible to cope with the size of the fluorescent lamp.

(d) Since the holding member is provided only at one end of the tubular globe, the fluorescent lamp may be inserted into the tubular globe through the holding member from the side where the holding member is provided. The work can be performed very easily as compared with the case where the holding members are provided at both ends of the flat globe and the other end has to be inserted into the other holding member by operating only one end of the fluorescent lamp 1.

(e) Since the holding member is provided only at one end of the tubular globe, the fluorescent lamp can be moved in a conical or pyramidal shape around the holding portion by the holding member, and both ends of the tubular globe can be moved. Compared with the case where the fluorescent lamp is fixed due to the holding member, the influence of properness of fitting into the socket due to the size of the fluorescent lamp and dimensional error between products is reduced, and the practical advantage is great. .
