Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a recessed lighting fixture that is attached to a ceiling or the like.

(Prior Art) In general, a recessed lighting fixture in which a support bracket is attached to the outside of a mounting base frame in a vertically adjustable manner and is supported at the lower end of the support bracket on the upper surface of a ceiling, etc. This is done by inserting the lighting fixture into a hole in the ceiling (see, for example, Japanese Utility Model Publication No. 56-41297).

(Problem to be solved by the invention) However, since protruding objects such as ducts are installed above the ceiling board, the lighting equipment may be subject to restrictions in the height direction depending on the installation location. It was troublesome to have to prepare lighting fixtures of different heights depending on the installation location.

In addition, the light distribution angle of recessed lighting fixtures installed in stores etc. may be changed due to changes in the interior of the store, etc. In that case, it is necessary to change the reflector, and the reflector must be changed accordingly. Since it is also necessary to change the mounting base frame, etc., the entire lighting fixture must be replaced, which is also troublesome.

The present invention has been developed in view of these points, and by dividing the mounting base frame into two parts, which are removably connected, the height can be changed and the light distribution angle can be adjusted by replacing the upper frame. The aim is to provide a recessed lighting fixture that can be modified.

(Means for solving the problem) The present invention provides the above-mentioned recessed lighting equipment.
The mounting base frame is divided into a cylindrical upper frame and a cylindrical lower frame having a larger diameter than the upper frame, and the upper frame is coupled to the lower frame so that it can be attached to and detached from below. , a socket and a reflector are supported by the upper frame, and the support fitting is provided on the outside of the lower frame.

(Function) After the lower frame is supported on the upper surface of the ceiling at the lower end of the support fitting provided on the lower frame, the upper frame of a predetermined height is joined to the lower frame from the lower side of the lower frame.

Furthermore, the upper frame can be removed from the lower frame together with the socket and reflector while the lower frame is supported on the upper surface of the ceiling.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a recessed lighting fixture, and its mounting base frame 2 is attached to a cylindrical upper frame 3 and a cylindrical lower frame 4 having a larger diameter than the upper frame 3. It is divided.

The outer part of the lower edge of the upper frame 3 and the inner part of the upper edge of the lower frame 4 are removably connected by a connecting means 5, thereby attaching and supporting the lower frame 4 to the ceiling board. On the other hand, the upper frame 3 is detachable from below.

The coupling means 5 includes a spring member 8 whose base end is fixed to the upper horizontal part 4a of the lower frame 4 via a presser metal fitting 6 with a pair of screws 7, and a distal end of the spring member 8. roller member 9 pivotally connected to
and a circumferential groove 3a formed on the outside of the upper frame 3 into which the roller member 9 can be fitted and removed.

10 is a reflector, and an upper reflector member 11
and a lower reflector member 12, and can be engaged and disengaged by rotating both members 11 and 12 by a certain angle.

A socket 14 is attached to the upper side of the upper frame 3 via a mounting base 13, and a lamp 15 is provided in the socket 14.

Further, on the lower surface of the upper frame 3, a locking spring member 16 extending downward is fixed with a screw 17.
By locking 1a, the entire reflector 10 is supported.

A support fitting 18 is provided at the bottom of the lower frame 4 so as to be adjustable in the vertical direction, and a ceiling plate S is provided between the lower end of the support fitting 18 and the lower flange portion 4b of the lower frame 4.
The entire lighting fixture 1 is supported by sandwiching them.

With the above configuration, when installing the lighting fixture 1, first fit and insert the lower frame 4 into the mounting hole Sa of the ceiling plate S, and adjust the position of the support fittings 18, 18 in the vertical direction to attach the lower frame. Install only 4.

After that, the upper frame 3 of a predetermined height is moved from the lower side to the lower frame 4.
push upward through the interior of the Then, the roller member 9 resists the elastic force of the spring member 8,
It rolls along the outer circumferential surface of the upper frame 3 and finally fits into the circumferential groove 3a, thereby joining the upper frame 3 to the lower frame 4. At this time, the projecting piece 3a of the upper frame 3 engages with the notch 4c of the lower frame 4 and is positioned.

Then, a reflector 10 is attached that corresponds to the height of the mounting base frame 2 consisting of the upper frame 3 and the lower frame 4 and achieves a desired light distribution angle, and the lamp 15 is screwed into the socket 14.

In addition, the upper frame 3 can be replaced while the lower frame 4 is attached to the ceiling board S, and by replacing the upper frame 3 and reflector 10, the mounting height of the lighting fixture 1 and the light distribution angle can be changed. It can be carried out.

Furthermore, even in the case of the above modification, the lower frame 4 and the lower reflector member 12 can be made common, and the feeling seen from below can be made the same.

(Effects of the invention) Since the present invention is constructed as described above, it is possible to replace the upper frame while the lower frame of the mounting base frame is attached, allowing the height of the mounting base frame to be changed and the light distribution angle to be adjusted. Changes can be made easily.
