Description

[0001]
BACKGROUND OF THE INVENTION
The present invention includes an instrument body having an open bottom surface that is mounted in an embedding hole of a ceiling material, a socket that is mounted in the center of the inner surface of the instrument body, and a light source that is detachably mounted on the socket. The present invention relates to an embedded lighting apparatus having a frame that covers a lower peripheral edge of a main body.
[0002]
[Prior art]
Recessed luminaires of the above structure are known. The frame is a part that covers the lower periphery of the instrument body, and is indispensable in terms of appearance. The frame is attached using a special V spring or leaf spring, but its structure is complicated and costly.
[0003]
[Problems to be solved by the invention]
An object of the present invention is to provide a simple and inexpensive frame mounting structure, thereby providing an inexpensive embedded luminaire.
[0004]
[Means for Solving the Problems]
In the present invention, an instrument body having an open bottom surface that is mounted in a ceiling material embedding hole is provided. A main socket is provided at the center of the inner surface of the instrument body. A sub socket is detachably attached to the main socket. A light source is detachably attached to the sub socket. A frame is provided that covers the lower periphery of the instrument body. A mounting hole for engaging with the sub socket is provided in the frame.
The mounting structure of the sub socket with respect to the main socket is a frame mounting structure.

DETAILED DESCRIPTION OF THE INVENTION
The embodiment of the present invention shown in FIG. 1 will be described. The embedded lighting fixture of FIG. 1 includes a fixture main body 10 with an open bottom surface that is mounted in a buried hole 92 of a ceiling material 90. A main socket 20 is provided at the center of the inner surface of the instrument body 10. A secondary socket 30 is detachably attached to the primary socket 20. A light source 40 is detachably attached to the sub socket 30. A frame 50 covering the lower peripheral edge 12 of the instrument body 10 is provided. A mounting hole 52 that engages with the sub socket 30 is provided in the frame 50.
The frame 50 is a decorative frame that nicely covers the lower surface side. It is formed by integrally molding a frame main body portion 54 that covers the periphery and a central portion 56 that connects the vicinity of the attachment hole 52. The central portion 56 shown in the figure has a bottomed cylindrical shape that also serves as a reflector. For example, the central portion 56 may be a non-reflecting structure having a cross-shaped radial shape.
The main socket 20 receives the screwed portion of the sub socket 30. The sub socket 30 receives a screwed portion (base) of the light source 40. The pair of screwed portions described above are of the same shape and size. The light source 40 is a light bulb. A portion of the mounting hole 52 of the frame 50 is engaged with the sub socket 30 and is held by the sub socket 30. The secondary socket 30 is like a mounting screw for that purpose.
FIG. 1 shows one type of instrument main body 10 and one type of frame 50. In practice, various types of the former and the latter are prepared, and any one of them is selected and combined. Thus, a wide variety of embedded lighting fixtures can be provided at low cost that can be selectively used according to the application and preference. The frame 50 mounting structure of the sub socket 30 and mounting hole 52 type formed at the center of the instrument is highly versatile and easy to share.
Another embodiment of FIG. 2 will be described. Reference numeral 60 denotes an infrared sensor attached to one part of the frame main body 54. Human detection is performed by the infrared sensor 60, and blinking of the light source 40 is appropriately controlled according to the result. The infrared sensor 60 branches from the sub socket 30 and is connected to a wiring 62 hidden on the upper surface of the frame 50. The frame 50 in FIG. 2 also serves as an attachment member for the infrared sensor 60. The other points are the same as in FIG. 1, and the component codes are the same as those in FIG.
Another embodiment of FIG. 3 will be described. A large screwed portion of the sub socket 30 is screwed into the main socket 20. The sub socket 30 receives a small screwed portion (base) of the light source 40. In this case, the sub socket 30 also serves as an adapter for adapting the small screwed portion of the light source 40 to the large main socket 20. The other points are the same as in FIG. 1, and the component codes in FIG. 1 are used as they are.
