Description

[Detailed explanation of the idea] This invention relates to lighting equipment.

As shown in FIGS. 1 and 2, conventional floor spot type lighting equipment has a U-shaped mounting base 2 whose horizontal pieces are fixed to a box body 1 that has openings on the front and top surfaces. A vertical piece of a U-shaped socket base 3 is rotatably supported by a vertical piece, a socket 4 is fixed to a horizontal piece of the socket base 3, and a spot lamp 5 is attached to this socket 4. The direction adjustment was carried out by holding the spot lamp 5 in a hand 6 and rotating the socket base 3 to adjust the angle of the spot lamp 5, as shown in FIG.

However, in such conventional lighting equipment, since the spot lamp 5 becomes hot during lighting, it is impossible to directly touch the spot lamp 5, and it is very difficult to adjust the irradiation direction.

Therefore, an object of this invention is to provide a lighting fixture in which the lamp irradiation direction can be easily adjusted even when the lamp is turned on.

An embodiment of this invention is shown in FIGS. 4 and 5.

That is, in this lighting fixture, an L-shaped handle/guard 7 is attached to the socket base 3, and the handle/guard 7 covers the front and top surfaces of the spot lamp 5.

In this case, the handle/guard 7 is formed by fixing a plurality of horizontal bars 7b to a U-shaped frame 7a formed by bending a wire rod into a U-shape, and
It is bent to form a letter-shaped guard surface, and both ends of the U-shaped frame 7a are bent outward to form hook pieces 7C and 7d.
Holes 3a and 3b are provided in both vertical pieces of the socket base 3, which is formed by bending a metal plate into a U shape, and the front portions of the through holes 3a and 3b in both vertical pieces of the socket base 3 are pressed or shaped. A pair of protrusions 3C, 3d, 3e, and 3f are punched inward.
, and applying force in the direction of arrow A with the end of the U-shaped frame 7a to compress the gap between the hook pieces 7C and 7d,
In this state, insert both ends of the U-shaped frame 7a into the through holes 3 of the socket base 3.
By bringing it close to the protrusions 3C, 3d, 3e, 3f and releasing the force, both ends of the U-shaped frame 7a are expanded to engage between the protrusions 3C, 3d and the protrusions 3e, 3f, and are hooked. The pieces 7C and 7d are fitted into the through holes 3a and 3b.

As a result of this structure, the lamp irradiation direction can be adjusted by holding the handle/guard 7, so that adjustment can be easily performed even when the lamp is lit.

In addition, the spot lamp 5 can be protected by the handle/guard 7 regardless of the direction of the spot lamp 5, which is safe, and unlike installing a guard over the entire opening of the box body 1, a small guard can be used. , can be manufactured at low cost.

Further, the handle/guard 7 is constructed by fixing a plurality of horizontal bars 7b to a U-shaped frame 7a formed by bending a wire rod into a U-shape.
Both ends of the U-shaped frame 7a are bent outward to attach hook pieces 7C and 7d.
On the other hand, through-holes 3a and 3b are provided in both vertical pieces of the socket base 3, which is formed by bending a metal plate into a groove shape. are pressed inward using a press to form a pair of protrusions 3C and 3d, respectively.
, 3e, and 3f, the handle/guard 7 can be easily attached to the socket base 3 with a simple structure.

Further, since the handle/guard 7 is easy to attach and detach, the lamp can be easily replaced.

Furthermore, even without removing the handle/guard 7 from the socket base 3, the lamp can be turned on simply by disengaging the protrusions 3C to 3f (applying force in the direction of arrow A) and rotating the handle/guard 7. Exchanges can be made.

As described above, the lighting equipment of this invention includes a U-shaped mounting base, a U-shaped socket base in which both vertical pieces of the U-shaped socket base are rotatably connected to both vertical pieces of the U-shaped mounting base, and It consists of a socket mounted upward on the horizontal piece of the socket base, a lamp attached to this socket, and a U-shaped wire bent to form an approximately L-shaped guard surface. A handle/guard whose opposite ends are rotatably inserted into the shaft holes of both vertical pieces of the U-shaped socket base, and a handle/guard provided on the inner surface of the U-shaped socket base so as to cover the lamp. Since it is equipped with a protrusion that restricts rotation, it is easy to adjust the direction of lamp irradiation while the lamp is lit, and it also protects the lamp.Furthermore, the handle and guard can be easily attached and removed, making it easy to replace the lamp. Furthermore, by pinching both vertical pieces of the U-shaped wire rod and releasing the engagement with the protrusion, the handle/guard can be easily rotated, making it easy to rotate the lamp without removing the handle/guard. Exchanges can be made.
