Description

[Detailed description of the invention] This invention is a lighting device in which two or more annular fluorescent lamps of different wattage are installed, and these lamps and the main body of the device are removably connected via a plug extending from the lamp socket. Regarding.

Conventionally, in this type of lighting equipment, for example, 30W and 40W
As shown in Figure 1, a 40W lamp 2 with a larger ring diameter than a 30W lamp 1 is attached to a 30W lamp 1, which is equipped with one annular fluorescent lamp (hereinafter simply referred to as a lamp).
They are arranged concentrically so that
Plug receivers 6 and 7 are provided to be connected to each 0W ballast element (not shown), and the plug receiver 6 connected to the 30W ballast element is connected to a plug 8 connected to the 30W lamp 1. Then, the plug receiver 7 connected to the 40W ballast element is connected to the plug 9 connected to the 40W lamp 2.

Each plug 8, 9 has a connecting pin 10.11 protruding from one end to be inserted into the plug receiver 6, 7, and an electric wire 12.13 connected to the connecting pin 10.11 is led out from the other end, Further, at the other end of this electric wire 12.13, each lamp 1,
2 and the lampholder 1 coupled to the terminal pin 16.17
4.15 is connected.

Note that 18 is a lamp holder and 19 is a shade.

In the lighting fixture configured in this way, the lamp 1,
2, after uncoupling the plugs 8 and 9 from the appliance body 3, remove the lamps 1 and 2 from the lamp holder 18, and connect the new lamps 1 and 2 to the lamp sockets 14 and 15. After that, place the lamps 1 and 2 in the lamp holder 18.
After that, plugs 8 and 9 can be connected to plug holders 6 and 7, respectively, so there is no need to attach or detach lamp holders L-14 and 15 when lamps 1 and 2 are adjacent to each other. This makes it easier to replace the lamps, and prevents the lamps 1 and 2 from cracking when the lamp sockets 14 and 15 are attached and detached.

Also, for lamp sockets 14.15 with built-in electronic starters, if the electronic starter fails, the lamp sockets 14.15 and plugs 8,
9 can be replaced with new parts, and even an electrical amateur can easily perform the replacement work.

However, since the lamp socket 14 connected to the 30W lamp 1 and the dump socket 15 connected to the 40W lamp 2 have different lengths of the electric wires 12.13, incorrect connection to the respective lamps 1 and 2 may occur. No, but plug 8,
9 and the plug receivers 6 and 7 are formed identically to each other, so the plugs 8 and 9 are mistakenly connected to the plug receiver 6 on the power side.
, 7 may be combined.

In such a case, the lamps 1 and 2 cannot be lit or have a short lifespan.

This invention was made to improve the above-mentioned drawbacks.

An embodiment of this invention will be described below with reference to FIG.

FIG. 2 is an enlarged perspective view of the main parts, and the components shown below are constructed in the same manner as in FIG. 1 above.

That is, in FIG. 2, 6 is a plastic 30W plug receptacle with a plug insertion surface 61 colored by mixing the application material in the raw material exposed on the lower surface of the device body 3, and 62 is a 30W plug receptacle on the plug insertion surface 61. The hole 7 is made of plastic and has a plug insertion surface 71 colored in a different color from the 30W plug receiver 6 exposed on the lower surface of the device main body 3. 40W plug receiver, 72 is a round and square plug connection pin insertion hole drilled in the plug insertion surface 71 of this plug receiver 7, 8 is a plug that is coupled to the 30W plug receiver 6, and the outside The shell surface is colored in the same color as the plug insertion surface 61 of the plug receiver 6.

9 is connected to the 40W plug receiver 7, and the outer shell surface is connected to the 40W plug receiver 7.
It is colored in the same color as the 0W plug receiver 7.

In the lighting fixture configured in this way, the lamp 1,
2 and plugs 8, 9 and a plug receiver 6 for connecting the lamps 1, 2 with the internal wiring of the appliance body 3 that matches the wattage.
. , 9 to the plug receivers 6, 7, the compatible plug receivers 6, 7 can be identified at a glance, and erroneous coupling can be prevented.

In addition, as shown in the above embodiment, when the electronic starter is built into the lamp socket (14.15), the characteristics of the electronic starter deteriorate depending on the polarity, so the plug connection pin 1
0.11 are formed into different shapes from each other, and the plug connection pin insertion holes 62 of the plug receivers 6 and 7 are formed in accordance with the shapes.
．． By setting the shape of 72, the polarity of the electronic starter is also prevented from being connected to the opposite polarity.

In the above embodiment, the plug receivers 6 and 7 are provided on the lower surface of the instrument main body 3, but the plug receivers 6 and 7 may be provided exposed on the side surface of the instrument main body 3.

Since this device is configured as explained above, the lamp and the internal wiring of the fixture body that matches the lamp's wattage are connected without error, which prevents lamp malfunctions and shortened lamp life. , its practical value is high.

[Brief explanation of the drawing]
