Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lighting fixture for fluorescent lamps mainly used at home.

This type of lighting equipment is, for example,
As shown in Japanese Patent No. 20681, many devices are composed of a wiring device, a chassis on the top surface, and a cover on the bottom surface. That is, the wiring device has a glow socket, a night light socket, etc. on its main body, connects the lead wire of the fluorescent lamp socket to form a unit, and installs the wiring device as a unit inside the chassis. Attach the cover to the bottom opening of the lamp, make through holes corresponding to the glow socket and night light socket in the chassis or cover, and attach the glow lamp and night light to the glow socket and night light socket through these through holes. I try to do that.

By the way, with regard to such lighting equipment, laws and regulations related to electrical appliances require that the base of the glow lamp and night light be prevented from touching the chassis or cover made of a metal plate such as a steel plate when the glow lamp or night light is installed or removed. . In other words, when attaching or removing a glow lamp or night light to its socket by screwing it into or removing it, even if the center terminal at the top end of the cap is away from the center terminal of the socket, the outer terminal of the cap may come into contact with the inner peripheral terminal of the socket. The outer terminal of the cap must not come into contact with the chassis or cover when the cap is in use.

In this case, a gap is formed between the open end of the socket of the wiring device and the inner surface of the chassis or cover,
If this gap is set to be longer than the length of the base of the glow lamp and night light (usually 20 mm for the base of the glow lamp and 15 mm for the base of the night light), the base will naturally be Although the socket and the chassis or cover do not come into contact with each other at the same time, if this is done, the overall height of the chassis and cover becomes thicker than necessary, which is undesirable as it increases the size.

For this reason, the gap between the open end of the socket of the wiring device and the inner surface of the chassis or cover is made as small as possible. An insulating synthetic resin bushing is attached to the edge of the hole to prevent electric shock from touching the edge of the glow lamp or night light base.

However, such a device requires bushing of the through hole, resulting in poor assembly workability and increased costs.

The present invention aims to improve the above-mentioned points, and aims to ensure safety when installing and removing glow lamps and night lights, and to facilitate assembly. It is.

The lighting device of the present invention includes a wiring device 11 to which the lead wire 34 of a fluorescent lamp socket 35 is connected, a metal chassis 41 to which the wiring device 11 is attached inside, and the underside of the chassis 41 as described above. The wiring device 11 includes a main body 12 and a metal cover 61 attached to cover the wiring device 11.
A cylindrical glow socket 13 and a night light socket 14 each having a lamp mounting opening at the lower end are protruded from the lower surface of the lamp.
