[Detailed description of the device]

[0001]

[Industrial applications]

  The present invention relates to a lighting device for illuminating a lower part such as a downlight attached to a ceiling, More specifically, it relates to a mounting structure for mounting a reflecting mirror inside a lighting fixture.

[0002]

[Prior art]

  Lighting fixtures that illuminate below, such as downlights, are usually cup-shaped surrounding the lamp. The reflector of the lamp is equipped, and the light from the lamp is reflected downward by this reflector. It is designed to make effective use of light. Such a reflector generally includes the reflector as a main body. Screw it on, or provide a concavo-convex part on the upper end of the reflecting mirror. Part is fitted to the inwardly biased mounting spring provided on the main body of the lighting fixture to mount the reflector It has a structure to open. However, forming the circumferential irregularities on the reflector is There was a problem that it was difficult and costly. Also, attach the lamp to the socket Since the entire part is surrounded by a reflector, cooling around the mounting part will be insufficient and the lamp life will be reduced. There was a life-saving problem.

[0003]

[Problems to be solved by the device]

  Therefore, an object of the present invention is to attach the reflector to the body of the luminaire with a simple structure. And do not surround the mounting part of the lamp to the socket, and cool the surroundings of the mounting part sufficiently. To provide a mounting structure for mounting a reflector inside a lighting fixture is there.

[0004]

[Means for Solving the Problems]

  In order to achieve such an object, according to the present invention, a reflector is mounted inside a lighting fixture. It is a mounting structure that has a plurality of vertical surfaces on its inner surface, and the surfaces of these vertical surfaces are Main body with flat grooves and a circular opening through which the lamp passes With a reflector that reflects the light of the lamp downwards and a double-ended mirror. A number of mounting members, and the folded-back end of the mounting members is within the opening of the reflecting mirror. The mounting member can be fixed to the opening by sandwiching the end. The length of the inside of the opening of the reflector at the mounting position and the inner surface of the main body at a position lower than this Provided is a reflector mounting structure for a luminaire, which is longer than a length connecting with a groove on a vertical surface.

[0005]   Further, a plurality of rectangular notches are provided around the opening of the reflecting mirror, and It is preferable that the folded end of the attachment member has a width smaller than that of the cutout portion.   In addition, the reflector reflects light from the light emitting portion and a spherical surface centered on the light emitting portion of the lamp. It is preferably composed of a reflecting surface that reflects downward.

[0006]

[Action]

  According to the above configuration of the present invention, the lamp is removed, and the folded ends of the plurality of mounting members are reversed. When fixed to the inner end of the opening of the reflecting mirror and pushing the reflecting mirror inward along the axis of the main body , The outer ends of the mounting members engage with the grooves on the vertical surface of the inner surface of the main body, The reflectors can be flexed and bulged together and the reflector can be mounted in a central position.

[0007]   Conversely, remove the lamp, insert your finger through the circular opening on the top of the reflector, The reflector can be removed by removing the material from the groove on the vertical surface of the inner surface of the main body.   Also, the circular opening on the top of the reflector is below the mounting part of the lamp socket. Since it can be done, do not surround the mounting part of the lamp to the socket, and cool the periphery of the mounting part sufficiently. be able to.

[0008]   Therefore, the reflector can be attached to the body of the luminaire with a simple structure, and Can be cooled sufficiently without surrounding the mounting part of the pump to the socket. Provided is a mounting structure for mounting a reflector inside a lighting fixture.
