プリント基板を配設したものである。The lighting fixture according to the present invention is a lighting fixture in which a printed circuit board on which electronic components are mounted is installed in a lighting fixture body made of metal and a plastic cover that covers the lower surface of the lighting fixture body. The printed circuit board is arranged so as to face the instrument body.
第１図及び第２図は本考案の実施例を示すものであり、
以下図面に基づき説明する。1 and 2 show an embodiment of the present invention,
A description will be given below with reference to the drawings.

照明器具の点滅切替えを行なうスイッチを操作するため
のスイッチ引き紐である。Similar to the conventional example, this embodiment is a hanging lighting fixture with a cord hanging from a round fluorescent lamp as a light source. The printed circuit board 3 on which various electronic components 2 are mounted is installed in the cover 5 and the outer flanges at the peripheral edges thereof are abutted and fixed to each other. Has been. Then, a shade (not shown) is placed on the luminaire main body 1 for use. 7 is a power cord 6
A cord cover for covering the mounting portion of the lighting fixture main body 1 and a switch drawstring 8 for operating a switch for switching the blinking of the lighting fixture.
カバー５の内面には、プリント基板３を取り付けるため
に、複数の載置突起９と複数の取付爪10とが突設されて

簡単で部品点数が少なくでき組立が容易である。In this luminaire, the electronic component 2 mounted on the printed circuit board 3 faces the luminaire main body 1 made of metal, and the plastic cover 5 has a surface opposite to the side on which the electronic component 2 of the printed circuit board 3 is mounted. Even if the electronic components 2 face each other and some trouble occurs, the plastic cover is less likely to be adversely affected and the entire lighting fixture is less likely to be disturbed.
Also, the mounting projection 9 and the mounting claw 10 are attached to the plastic cover.
Since the printed circuit board 3 is attached so as to project, the structure is simple, the number of parts can be reduced, and the assembly is easy.
なお、前記の実施例は吊り下げ照明器具であるが、直付
