CONSTITUTION:A reflector type candescent lamp 1 is attached to one end of a flexible cylindrical member 7 made into a bellows-formed metal tube of stainless steel or the like and an insulative member 10 is fixedly attached to the other end. A screw base 14 as an electricity supply terminal is fitted over the insulative member 10 at the rear of a flange portion 13 provided thereon. Outer lead wires 6, 6 connected to the filament 4 of the candescent lamp 1 are passed through the interior of the flexible cylindrical member 7 and one of the lead wires is attached to the base 14 and the other is attached to the central terminal 16. When screwed in a socket installed on a ceiling or wall or in an existing lighting fixture, its illuminating direction can be freely selected.

Description

[Detailed Description of the Invention] [Technical Part of the Invention] The present invention relates to a directional lamp in which the direction of the lamp can be freely changed and the irradiation direction is variable. [Points] Stands using incandescent light bulbs and dim light lamps are widely known as lighting devices in which the direction of illumination can be varied by changing the orientation of the lamp. The stand consists of a support made of six flexible members that bends freely to change the posture of the lamp provided at the end of the support U. However, the stand must be placed stably on a desk etc. due to the following conditions:
'! ”: J'i4 and has a large base portion in shape.

Therefore, it cannot be used facing the ceiling or wall.

[Purpose of the invention]

The present invention has been made based on the above-mentioned circumstances, and its purpose is to be able to be used by being attached to an existing light socket or a socket or outlet attached to a ceiling or wall. Therefore, the ceiling
The aim is to provide a directional lamp that can be installed on a wall.

[Axis of invention: Essential]

That is, in the present invention, a lamp is attached to one end of a flexible cylindrical body, an insulator is fixed to the other end of the flexible cylinder, a power supply terminal that can be connected to a socket or an outlet is attached to this insulator, and this power supply, The terminal and the lamp are connected by an insulated lead wire inserted into the OI return cylinder.

[Embodiment 1 of the Invention] Below, a first length example of the present invention will be explained based on FIGS. 1 to 3.

In the figure, l is a reflective incandescent light bulb, and glass bulb 2
It has a reflective surface 3 made of an aluminum film on its inner surface, and a filament 4 is housed in the bulb 2P.

The filament 4 is connected to external leads 6, 6 via internal leads 5, 5.

2 is a flexible cylindrical body, which is formed into a bellows shape from a metal tube such as stainless steel. ing.

A cap portion 8 is integrated with one end of this flexible cylinder 7,
The cap portion 8 is provided separately and is fixed to the back surface of the light bulb 1 via an adhesive 9 such as base cement. Incidentally, instead of the adhesive 9, the bulb 1 may be supported by peeling off the cap portion 8. Flexibility f≦°1
The other end of the body 7 is fixed to the insulator 1θ. Insulator lO
is made of synthetic resin or ceramic, for example, and has a through hole 11 formed in the center that allows the above-mentioned material to be inserted. Force fitting of the other end of the cylinder body 7:
It has been i41. The cylindrical body 70 is mechanically connected to the insulator 10 by caulking 12, adhesive, or other means.

At the rear of the seven lamp portions 13 formed on the insulator 10,
The screw-in type base 14 as a power supply terminal is completely attached. The cap 14 is screw-fitted onto the locking ligature 10 and identified by adhesive or caulking. The cap 14 is made of unspun glass, insulating cement, or the like, as is well known, and has a center terminal 16.

The external lead wires 6, 6, which are connected to the filament 4 of each frost, pass through the flexible cylinder 7, and the first one is connected to the base 14, and the other one is connected to the center. 11,: Child 16
Greetings and continuation 2. Next, lever external lead wire 6
, 6 has been damaged by greenery due to glass i>fd, varnish tube, etc.

In the fire example lamp having such a configuration, the screw-type base 14 is attached to a socket 19, which is shown in FIG. . The seven caps 14 are mechanically and electrically connected to a known holder (not shown) in the socket 19, and are electrically connected to a known contact/forcer (not shown) in the center terminal 16. Awn. Therefore, lightning,
The light source 1 is connected to the power source through the external saw wire 2 and 6. In such an attached state, as shown in Fig. 3, when the direction (posture) of the bulb l is manually manipulated, the flexible cylindrical body 7 freely bends and deforms, so the direction of the bulb l changes. Therefore, in 1), opposite directions can be arbitrarily connected. In the above embodiment, the flexible cylinder 7 and the cap 14 are kept in a non-conductive state by the insulator lO. Therefore, there is a risk of electric shock even if the cylindrical body 7 is exposed to the outside. At this time, it is possible to prevent the little finger from touching the base 14.

The external lead wires 6, 6 are bent by bending the flexible cylindrical body 7, so that the external lead wires 6, 6 can be Contact with the cylinder body 7 (even if the cylinder body 7 is not energized even if the external lead wire 6.
Even if 6 come into contact with each other, they will not be short-circuited.

In the above embodiment, the screw-type base 1 is used as the power supply terminal.
4) 'CS combination was explained, but Mizumoto 1! , I
For example, you can use the plug terminal 41.41 (or 2) by inserting it like a mizuko into the 4th figure of the rug. The external lead wire 6.6 should not be connected by screws 4.1.43 or the like.

1 iii rr" L included plus 1 connector 41. 41 can be installed on the ceiling or in the ml. For example, plug into a recessed outlet (not shown, not shown). It is mechanically engaged with the connection ζi0. In place of the plug-in plug terminal 41.41, the hook may be a hook-type terminal claw for sealing. In the example, a solar thermal light bulb L is used.7
7) For the conjunction, rtM/ξ is the fifth light source.
As shown in the figure, a halogen light bulb 61 and a reflecting mirror 52 may be combined. In this case, the flexibility f+'r
The cap portion 8 with j 41 < 7 is connected to the back surface of the reflecting mirror 52 with an adhesive 9 or ρ-seal 7.

In Figure 6, an example is shown in which an all-island vapor discharge lamp such as a small metal halide lamp is used as a light source.
3 is J moss and it is a vegetable. In this case, the flexible cylinder 7
A case 64 is provided between the insulator lO and the insulator lO, and in this case 64, transformers, safety equipment, electronic components, etc.
It accommodates dynamic and lighting circuit components 654°. Therefore, when the base 14 is connected to the socket 19, the lamp 6) and the discharge lamp 6) start to turn on. In addition, six lights can be used without having to install special starting and lighting circuit parts externally.

In addition, in each of the above-mentioned implementation worlds 1, as crazy/1 case body 7,
Although I explained and explained the installation using a serpentine pipe, this book B
As shown in Fig. 7, for example, stainless steel 4
1) By forming the material 7 into a coil shape, it may be made into a cylindrical structure with dustability.

〔Effect of the invention〕

VAccording to the above-mentioned 9 points, if you connect the i7E terminal that can be accessed to the insulator to the socket of the existing light J↓, or the socket or outlet installed on the ceiling or wall. , Flexible 1/4: The direction of the lamp can be changed by the flexural bending action of the cylinder, and therefore the direction of the lamp can be changed. There is an advantage that the shooting direction can be freely selected.
