より形成されている。Embodiment An embodiment of this invention will be described based on FIGS. 1 to 4. In the figure, a device main body 1 has lighting components (not shown) such as a ballast placed inside it, has a base 2 at its upper end that can be attached to an incandescent lamp socket, and has a plurality of fitting holes 3 formed on its outer circumferential surface. ing. The lamp support arm 4 has an arc-shaped tip support portion 5 formed at its tip, and a pair of elasticity imparting slit grooves 8 and 9 crisscrossingly formed on the end surface 7 of the base end portion 6. Triangular protrusions 10 are formed on the left and right side surfaces of the base end 6 in the width direction, and on the upper surface of the base end 6 in the width direction of the horizontal slit groove 8, the height on the end face 7 side is large and the upper and lower sides of the arm 4 are A tapered surface 11 that protrudes beyond its width is formed. Further, a spring receiving projection 7a is formed on the end face. This lamp support arm 4 is fitted into the fitting hole 3, and at this time, the slit grooves 8 and 9 form the tapered surface 11 and the protrusion 1.
0 is elastically deformed and can be fitted. and protrusion 10
As shown in FIG. 4, the inner end 3a of the fitting hole 3 is engaged with the inner end 3a on both sides thereof, and the tapered surface 11 is engaged with the upper edge 14 of the inner end. A spring 13 formed of a coil spring is compressed and interposed between the spring receiving projection 7a of the end face 7 and a spring support portion 12 provided in the instrument main body 1 so as to bias the lamp support arm 4 to protrude. At this time, the lamp support arm 4 is prevented from coming out by the protrusion 10 and the tapered surface 11 against the spring 13, and the tapered surface 11 presses against the upper edge 14, pushing the end surface 7 side of the base end 6 downward, and the arm A gap is not created where the end surface 7 side of the lower surface 15 of the arm 4 floats up due to the weight of the arm 4, etc., and the arm 4 is prevented from hanging down due to the play between the arm 4 and the fitting hole 3, and a correct horizontal posture is maintained. Further, the tip support portion 5 of the arm 4 is pressed against the inner peripheral surface of the annular fluorescent lamp 16 to support the lamp 16. 17 is a lead wire, 18 is a cap base mounting screw, 19 is a lamp socket, and 20 is a lead wire extraction hole, which is formed by a notch at the joint between the cap base and the main body 1 of the device.
環形蛍光ランプ16を装着するときは、ランプ
支持アーム4を器具本体1内にばね13に抗して
後退させランプ16の内周に支持部5を当接させ
る。このときばね13によりランプ16が突張り
状態に固定される。 When installing the annular fluorescent lamp 16, the lamp support arm 4 is moved back into the device body 1 against the spring 13, and the support part 5 is brought into contact with the inner periphery of the lamp 16. At this time, the spring 13 fixes the lamp 16 in a tensioned state.
このように構成したため、この照明器具はつぎ
の作用効果がある。すなわち、
(1) テーパ面11が嵌合孔3の内端に係止するこ

点はテーパ面11の当る嵌合孔3の内端3aの
上縁14とアーム4の下面が当る外端3bの下
側となり、テーパ面11がないものと比べアー
ム4の垂れ下りを少なくすることができる。 With this structure, this lighting fixture has the following effects. That is, (1) Since the tapered surface 11 is engaged with the inner end of the fitting hole 3, the horizontal fulcrum of the lamp support arm 4 is the upper edge 14 of the inner end 3a of the fitting hole 3, which the tapered surface 11 touches. The lower surface of the arm 4 comes into contact with the lower side of the outer end 3b, and the hanging of the arm 4 can be reduced compared to a case without the tapered surface 11.
(2) テーパ面11が嵌合孔3の内端3aに係止す
ることにより外れにくく、ランプ交換等が煩雑
にならない。(2) Since the tapered surface 11 is engaged with the inner end 3a of the fitting hole 3, it is difficult to come off, and lamp replacement etc. are not complicated.
(3) 三角形突起10により、さらにランプ支持ア
ーム4を外れにくくするとともにアーム4の左

方向に回転しない。(3) The triangular protrusion 10 further makes it difficult for the lamp support arm 4 to come off, and also prevents the arm 4 from wobbling from side to side, and prevents the lamp 16 from moving in the circumferential direction when the base 2 of the main body 1 is attached to the socket. It doesn't rotate.
なお、この考案の照明器具は、器具本体1が口
金部2のないものにも適用できる。また、三角形
突起10もなくてもよい。 Note that the lighting fixture of this invention can also be applied to a fixture body 1 without a base portion 2. Further, the triangular protrusion 10 may also be omitted.
この考案によれば、テーパ面によりランプ支持
アームが外れにくく、またその垂れ下りを少なく
することができ、外観を良好にすることができる
という効果がある。
According to this invention, the tapered surface makes it difficult for the lamp support arm to come off, and the hanging of the arm can be reduced, resulting in a good appearance.
