Description

TECHNICAL FIELD The present invention relates to a lighting fixture.

[Prior Art] Conventionally, lighting equipment has been used by clearly distinguishing it from one using an incandescent lamp and one using a fluorescent lamp. However, with the advent of fluorescent lamps having a bulb-type base, the distinction between them has become less clear.

A fluorescent lamp that has recently been developed and has been put into practical use is called a compact fluorescent lamp, and can be used in place of a conventional incandescent lamp, and consumes less power than an incandescent lamp. The heat generation amount is reduced to about one-third, and the life is extended several times. Further, as miniaturization of fluorescent lamps has progressed, fluorescent lamps having a base on one side have been developed and are called compact fluorescent lamps or single-base fluorescent lamps.

[Problems to be Solved by the Invention] Although a fluorescent lamp having the same base as that of an incandescent lamp is often used, the fluorescent lamp has a high-frequency lighting circuit including a ballast and the like built therein. However, since the entire fluorescent lamp is replaced when it reaches the end of its life, there is a problem that it must be discarded even though the high-frequency lighting circuit is still fully usable. In addition, the recently developed single-ended fluorescent lamp uses a single-ended fluorescent lamp in place of the incandescent light bulb where the conventional incandescent lamp has been used, because the base has a base structure for fluorescent lamps. There was a problem that I could not do it.

The present invention solves the above-mentioned problems, and where an incandescent light bulb has been used, a single-ended fluorescent lamp can be immediately used in place of the incandescent light bulb, and furthermore, attachment and removal of the fluorescent light are easy. Assembling the lighting fixture is easy and simple, and even if the fluorescent lamp tube part and the high frequency lighting circuit are separated and the fluorescent lamp tube reaches the end of its life, the fluorescent lamp tube can be replaced without changing the high frequency lighting circuit. The purpose is to provide.

Furthermore, the conventional hook-and-hook type fluorescent lamp connection socket manufactured with standard dimensions only has a connector function and must be installed separately to protect the high-frequency lighting circuit and add user safety functions. However, there is a problem that it is complicated and expensive. Therefore, by providing a switch mechanism inside the fluorescent lamp connection mechanism manufactured with standard dimensions, the structure of the high-frequency lighting circuit as a fluorescent lamp lighting starter can be simplified and compact and inexpensive The purpose is to provide a connection socket. In particular, it is connected to an expensive high-frequency lighting circuit used for fluorescent lamp lighting fixtures that are not suitable for fluorescent lamp lighting starters consisting of ballasts, etc., and protects the high-frequency lighting circuit when removing the fluorescent lamp and touches the user by any chance. Even if there is no danger, a switch circuit is provided so that the power supply line to the high-frequency lighting circuit can be shut off, and a fluorescent lamp socket that can achieve a smaller safety effect can be provided. .

[Means for Solving the Problems] In order to solve the above problems and achieve the object of the invention, the lighting fixture according to the present invention is characterized by being configured as follows. That is, a substantially cylindrical container, a fluorescent lamp connecting portion recessed in the container surface, a fluorescent lamp lighting starter housed inside the container, and a light bulb projecting outside the container. In a lighting fixture having a base part screwed to a receiving member, a board on which a high-frequency lighting circuit as the fluorescent lamp lighting starter is mounted and a fitting hole for a fluorescent lamp connection mechanism housing section provided on the board are provided. The electronic components are arranged and arranged around the fluorescent lamp connecting mechanism housing portion inside the container. Further, it has a base of a fluorescent lamp having a lamp connecting pin on an end surface and a hook locking projection on a side surface, and a recess fitting to the fluorescent lamp base, and the fluorescent lamp base is inserted and twisted to make the hook.
