Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a recessed lighting fixture.

[Prior Art] Conventionally, as shown in FIGS. 2 and 3, this type of embedded lighting fixture is a bottomed cylindrical fixture with an outer flange 2 protruding from the periphery of the opening and housing a lighting lamp 3. The main body 1 is inserted into a main body mounting hole 5 formed in a mounting face plate 4 such as a ceiling plate, and a pair of main body support springs 6 provided on diagonal parts of the circumferential surface of the main body 1 and the outer flange 2 are used. A pair of reflecting plate holding means 10 are provided on diagonal lines perpendicular to the diagonal line connecting the main body support springs 6, for holding the mounting face plate 4 between them and detachably holding the reflecting plate 7 in the opening of the instrument body 1 by means of a holding spring 9. This reflecting plate holding means 10 is formed by a heart-shaped holding spring 9 pivotally attached to a diagonal portion of the back surface of the reflecting plate 7, and a locking claw 8 that engages with the lower part of this holding spring 6. , the elastic force of the retaining spring 9 (when compressing) the portion of the reflective plate 7 where the retaining spring 9 is formed.
By pushing upward against the retaining spring 9
The lower part of the wide part of the reflector plate 7 is fitted into the opening of the instrument main body 1 by engaging with the locking claw 8, and by pulling the reflector plate 7 downward against the elastic force of the holding spring 9. The engagement between the retaining spring 9 and the locking pawl 8 is released, and the reflection plate 7 is removed.
The lamp socket 3a into which the illumination lamp 3 is mounted is provided on a socket mount 12 screwed onto the upper bottom surface of the appliance main body 1, and the power line is drawn out through the power supply insertion hole 13.
Further, the notch hole 14 is a hole for locking the main body support spring 6.

[Problem to be solved] However, in the conventional example described above,
Since the reflector holding means 10 is provided on a diagonal line that is perpendicular to the diagonal line connecting the main body support spring 6, when the reflector plate 7 is attached or detached, especially when the reflector plate 7 is removed, the reflector plate 7 is held in place by the elastic force of the retainer spring 9. By pulling down against the applied force, a rotational moment is generated around the mounting position O of the main body support spring 6, and when the instrument main body 1 rotates due to this rotational moment, a large force is applied to the main body support spring 6. There has been a problem in that the main body support spring 6 may be deformed or loosened, resulting in poor adhesion of the appliance main body 1 to the mounting surface such as the ceiling surface.

The present invention was developed in view of the above points, and its purpose is to prevent the main body support spring from deforming or loosening even when the reflector is attached or detached, and to always keep the instrument body on the mounting face plate. To provide a lighting fixture which can be disposed in close contact with each other, has good heat dissipation, moderates the temperature conditions of electrical parts, and can use inexpensive parts.

[Means for Solving the Problems] The lighting device of the present invention has a bottomed cylindrical device body with an outer flange protruding from the periphery of the opening and housing a lighting lamp, which is inserted into a main body mounting hole drilled in the mounting face plate. and a reflector holder in which the mounting face plate is held between a pair of main body support springs provided on diagonal portions of the circumferential surface of the instrument body and the outer flange, and the reflector is detachably held in the opening of the instrument body by the holding spring. The retaining spring is formed by a heart-shaped spring pivotally attached to the reflector, and the reflector is retained by an engaging claw provided on the inner peripheral surface of the instrument body and engaged with the lower part of the retainer spring. form the means;
In a lighting equipment in which the reflector is attached by pushing the reflector upward and the reflector is removed by pulling the reflector downward,
The reflector holding means is provided near the main body support spring, and a side opening is provided on the peripheral surface of the instrument main body in a direction perpendicular to a diagonal line connecting the main body support springs.

[Function] The present invention is constructed as described above, and the bottomed cylindrical instrument body is inserted into the body mounting hole drilled in the mounting face plate, and a pair of diagonal portions of the circumference of the instrument body are provided. The mounting face plate is held between the main body support spring and the outer flange, and the holding spring pivotally attached to the reflecting plate is engaged with an engaging claw provided on the inner circumferential surface of the instrument main body, thereby providing a reflecting plate holding means. In a lighting fixture similar to the conventional example in which the reflector is mounted by pushing the reflector upward and removed by pulling the reflector downward, the engagement of the reflector holding means is provided. The claw is provided near the main body support spring, and when the reflector is removed, a large rotation moment is not generated in the instrument body, so even if the reflector is attached or removed, the main body support spring will not be deformed.
The device body can always be placed in close contact with the mounting face plate without any loosening. In addition, side openings are provided on the peripheral surface of the device body in a direction perpendicular to the diagonal line connecting the main body support springs, which improves heat dissipation and moderates the temperature conditions of electrical components, making it possible to use inexpensive components. I'm starting to be able to do it.

[Embodiment 1] FIG. 1 shows an embodiment of the present invention, in which a reflection plate holding means 10 formed by a locking claw 8 of a holding spring 9 is used in an embedded lighting fixture similar to a conventional example. is arranged near the main body support spring 6. In addition, in the embodiment, since the side opening 11 is provided in the instrument body 1 formed in an oval shape,
The heat dissipation of lamp heat has improved, and the temperature conditions for electrical parts (lamp socket 3a, power line, etc.) have become gentler, making it possible to use cheaper parts.

In the present embodiment, a reflector holding means 10 consisting of a locking claw 8 that engages with a holding spring 9 to hold the reflector 7 is provided near the main body support spring 6 that supports the instrument main body 1. Therefore, when the reflector plate 7 is removed, a large rotational moment is not generated in the instrument body 1. Therefore, even when the reflector plate 7 is attached and detached, the main body support spring 6 does not deform or loosen, and the instrument body 1 The mounting plate 4 can be disposed in close contact with the mounting face plate 4 at all times. Further, since the part where the locking claw 8 was provided in the conventional example becomes an empty space, by providing the side opening 11 in this part as in the embodiment, it is possible to improve the heat dissipation of the lamp heat. It's becoming like that.

[Effects of the invention] As described above, the present invention has a bottomed cylindrical instrument body inserted into the body mounting hole drilled in the mounting face plate, and a pair of bodies provided at diagonal portions of the circumferential surface of the instrument body. The mounting face plate is held between the support spring and the outer flange, and the retaining spring pivotally attached to the reflector is engaged with the engaging claw provided on the inner circumferential surface of the instrument body, thereby forming a reflector retaining means. This is a lighting device in which the reflector is attached by pushing the reflector upward and removed by pulling the reflector downward, and the engaging claw of the reflector retaining means is engaged with the reflector. Since it is located near the main body support spring,
When the reflector is removed, no large rotational moment is generated in the instrument body, and even when the reflector is attached or removed, the main body support spring does not become deformed or loosened, and the instrument body is always placed in close contact with the mounting face plate. This has the effect of being able to be set up. In addition, side openings are provided on the peripheral surface of the device body in a direction perpendicular to the diagonal line connecting the main body support springs, which improves heat dissipation and moderates the temperature conditions of electrical components, making it possible to use inexpensive components. There is an effect that it can be done.
