を的確に防止できる。Effect According to the present invention, the hook-shaped locking portion provided at the lower end of the coil spring has a bent portion that is bent downward and follows the socket, and this bent portion connects the neck of the reflector plate and the socket. By setting the inner diameter of the neck portion to be slightly larger than the outer diameter of the socket so as to be sandwiched between them, the inner diameter of the neck portion of the reflector plate can be minimized, thereby making it possible to minimize the inner diameter of the neck portion of the reflector plate. Since it becomes difficult for the reflector to come off, it is possible to accurately prevent the reflector from falling.

る。８はランプである。 The drawing shows an example of a downlight that is embedded in a ceiling 1. A socket 3 is attached to a main body 2 having a substantially U-shaped cross section with screws 4, and a coil spring 5 guided around the outer periphery of the socket 3 is attached to one end of the downlight. is attached to the main body 2, for example, with screws 6, and a hook-shaped locking portion 5a formed at the other end is locked in a hole 7b of a neck portion 7a of the reflector 7 to support the reflector 7. 8 is a lamp.

に大きく設定している。 More specifically, the hook-shaped locking portion 5a formed at the lower end of the coil spring 5 has a bent portion that is bent downward to follow the socket 3, and a folded portion that is folded back upward. is inserted into the hole 7b of the neck portion 7a of the reflector plate 7 from the inside, and the inner diameter of the neck portion 7a is set to be slightly larger than the outer diameter of the socket 3 so that the bent portion is sandwiched between the neck portion 7a and the socket 3. are doing.
反射板７の外周縁７ｃは、コイルバネ５の引張
力により天井１に圧接するが、外周縁７ｃが本体
２の開口縁２ａに当接する構成も可である。 The outer peripheral edge 7c of the reflector plate 7 is pressed against the ceiling 1 by the tensile force of the coil spring 5, but a configuration in which the outer peripheral edge 7c abuts against the opening edge 2a of the main body 2 is also possible.

できる。 According to the above configuration, since the reflecting plate 7 is pulled by the coil spring 5, wobbling of the reflecting plate 7 can be prevented, and since the coil spring 5 is guided by the socket 3, centering of the coil spring 5,
The centering of the reflecting plate 7 is improved, and the position of the reflecting plate 7 is well determined. Further, the hook-shaped locking portion 5a provided at the lower end of the coil spring 5 is bent downward to have a bent portion along the socket 3, and this bent portion is located between the neck portion 7a of the reflector plate 7 and the socket 3. By setting the inner diameter of the neck part 7a slightly larger than the outer diameter of the socket 3 so that it can be sandwiched between the reflector plate 7
The inner diameter of the neck portion 7a of the coil spring 5 can be minimized, thereby making it difficult for the hook-shaped locking portion 5a of the coil spring 5 to separate from the reflecting plate 7, thereby accurately preventing the reflecting plate 7 from falling.
