Description

[Detailed description of the invention] The purpose of this invention is to provide a safe and convenient lighting equipment whose power supply part can be freely attached and removed when lighting is not required or when the direction of lighting needs to be changed. do.

In order to achieve the above-mentioned purpose, the present invention installs a step-down transformer 2 inside the lid box 1, which lowers the voltage to, for example, 12V.
A jack terminal 3 connected to the low-voltage secondary coil is provided, and a low-voltage 12V light bulb 6 and a reflector 7 are attached to the other end 4b of the conductor/support 4, which has a plug 5 corresponding to the jack terminal 3 at the base end 4a. , insert the support base 4a into the lid box 1 through its insertion hole 1a.
The gist is that the plug 5 and the jack terminal 3 are removably fitted and connected to each other by inserting the plug 5 and the jack terminal 3 from each other.

Reference numeral 8 denotes an insulating terminal plate attached to the upper plate 1b of the lid box 1, and the extension part 3a of the jack terminal 3 is passed through this to connect the connecting terminal 9.
At the same time, secure with nuts 10.

The conductor/post 4 is inserted into terminals to which a plug 5 and a socket 6a of a light bulb 6 are to be connected at both ends of the metal tube via an insulator 11, and a cord 12 is connected therebetween.

The connection between the socket 6a and the conductor/post 4 may be the same as the connection between the plug/jack terminals 5 and 3.

Insert the base of the post 4 through the hole 1a and connect the jack terminal 3.
When the plug 5 is connected, one pole passes through the cord 11 and the other pole is grounded to the body via the metal tube support 4 to form an electric circuit, and a switch 13 provided in the lid box causes the light to blink.

Since the present invention has the above-mentioned structure, the lid box 1 is formed in a small volume and can be assembled by inserting the conductor/post 4 into the hole 1a when necessary to form an electric circuit, which is very convenient.

Particularly when transporting products, compact packaging is sufficient by disassembling the lid box, conductor/support, and reflective shade.

In this case, if the conductor/support column 4 is made into a split joint type, the packaging will be further reduced and it will be convenient.

By providing a plurality of jack terminals and pillar insertion holes in different directions in the container box, the lighting direction can be changed while the lid box 1 is fixed, as shown in FIGS. 3 to 5.

In addition, since the step-down transformer 2 is built into the lid box 1 and the light is lit on its low-voltage secondary side, there is no risk of electric shock even if the support 4 is used as a grounding circuit, and the user can freely use the support You can disassemble and assemble it by attaching and detaching it, or change the lighting direction.

Therefore, the electrical circuit to be connected only needs to have one pole, so for example,
No. 8-18028 and JP-A No. 46-32956 do not require a normal two-pole outlet.

Furthermore, since the voltage is low, a plug 5 and a jack terminal 3 are sufficient, which makes the power connection part compact and lightweight.

Figures 2 to 4 and 6 are examples of how the proposed lighting fixture is used. Figure 2 is a desk stand type, Figures 3 and 4 are examples of the lighting fixture being installed on a ceiling surface C1 and a wall surface W, respectively. The figure shows the lid box 1 of the present invention connected to an outlet 15 attached to a vertically long trolley 14 provided on the ceiling.

FIG. 5 shows a lid box 1 having a circular shape, and various other shapes such as a tabletop type can be applied.

16 is a fuse of the transformer.
