Description

[Detailed explanation of the idea] 〔Technical field〕 The present invention relates to a recessed lighting fixture.

[Background technology]

As awareness of energy conservation increases, more and more insulation materials are being installed in ceilings and other areas to improve efficiency during winter heating, especially in cold regions. Among the various insulation methods, the blowing method, in which small pieces of insulation material are blown in, can be applied to every nook and cranny. Insulating material covers the molded lighting fixtures, and the mounting dimensions can be changed according to the dimensions of the construction material. There was a fear that it would get dirty.

[Purpose of the invention]

The present invention is a recessed lighting fixture whose mounting dimensions can be changed according to the dimensions of the building materials, without allowing insulation material or dust to enter the lighting fixture even when insulation material is installed under the ceiling using blowing method, etc. The purpose is to provide.

[Disclosure of invention]

The present invention enables recessed lighting equipment such as downlights to be compatible with the installation of cross-sectional materials in ceilings while making the installation dimensions variable in accordance with the dimensions of construction materials, as shown in Figures 1 and 2 below. This will be explained based on examples.

The lighting equipment main body 1 has a closed top surface and an open bottom surface (cylindrical shape with an outer flange at the bottom end), and two symmetrical mounting holes 2 having a longitudinal axis in the vertical direction are provided on the side surface. The mounting bracket 3 is an elastic thin sheet metal with a screw 4 set upright at the upper end, and the lower end of the divided end is attached to the construction material. The screw 4 is inserted into the mounting hole 2 from the outside of the lighting fixture body 1. The shielding plate 5 is attached to the lighting fixture body 1 with an elastic thin plate made of rubber or the like so as to cover the mounting hole 2. A vertical slit 6 is provided approximately in the center, and a screw 4 of the mounting bracket 3 protrudes from the slit 6 into the lighting fixture body 1.A washer 7 is attached to the screw 4 that protrudes into the lighting fixture body 1. A knob nut 8 is screwed through the socket to fix the mounting bracket 3 to the lighting fixture body 1.A socket 9 is installed approximately at the center of the inner surface of the top surface of the lighting fixture body 1, and an incandescent light bulb 10 is mounted as a lamp. The reflector plate 11 is formed of a thin aluminum plate so as to cover the incandescent light bulb 10, and the inner surface is a reflective surface.The reflector plate mounting frame 12 is formed in an annular shape with a U-shaped cross section. Frame mounting springs 13 are attached to two centrally symmetrical locations, and the light fixture body 1 is lifted up and suspended by the frame mounting springs 13, and the reflector 11 is placed with the end surface of the outer peripheral rising portion in contact with the ceiling surface. ing.

In this embedded lighting fixture, a shielding plate 5 that covers the rectangular mounting hole 2 of the lighting fixture body 1 is formed of an elastic material, and the mounting bracket 3 is fixed by inserting screws 4 into slits 6 provided in the shielding plate 5. The mounting bracket can be fixed in any position according to the dimensions of the construction material, and since the mounting hole 2 is covered, insulation material and dust will not get into the lighting equipment even when installing ceiling insulation. The mounting bracket 3 is fixed without loosening due to the elasticity of the shielding plate 5 formed of an elastic body, and the lighting fixture can be reliably mounted even when vibrations are applied.

[Effect of idea]

According to the present invention, a shielding plate made of an elastic material and having a slit in the center covers the elongated mounting hole of the lighting equipment body, and is inserted through the mounting hole and the slit to fix the mounting bracket. The position of the mounting bracket can be changed according to the dimensions of the construction material, so there is no possibility of insulating material or dust getting into the lighting fixture body even when installing insulation in the attic.

Claims (1)

[Scope of utility model registration request] In recessed lighting equipment, in which the lighting equipment body with a socket for attaching the lamp is embedded into the ceiling, multiple long holes with long axes up and down are provided on the side of the lighting equipment body, and a slit is formed approximately in the center. A shielding plate made of an elastic material and having a slit approximately aligned with the long axis of the mounting hole is attached to the lighting fixture body, covering the mounting hole, and protruding outside the lighting fixture body so that the lighting fixture body can be attached to the ceiling surface. A recessed lighting fixture comprising a fixture that is fixed to the fixture and inserted into the mounting hole and the slit so as to be vertically movable and fixed from within the lighting fixture body.
