Description

[Detailed Description of the Invention] [Technical Field] This invention relates to a lighting fixture that is applied to table lighting and the like.

[Background technology]

A conventional table pendant is shown in FIG. That is, a lamp socket 3 is attached to a socket base 2 having a switch 1, and a main body 4 covering these is attached.
A collar 5 is provided at the lower end of the shield 6 to support the shade 6, making it easy to remove the shade 6 and clean it. 7 is a lamp, and 8 is a hanging cord. However, this lighting fixture has a drawback that when an external force is applied to the shade 6, the shade 6 tends to come off because the dimension A is shallow. In addition, since the end of the collar 5 was left separated, there were concerns about its strength. On the other hand, since there is no hole in the ceiling, heat builds up around the lamp cap, increasing the temperature of the cap and switch, and the surface of the main body 4 becomes dark, resulting in poor aesthetic appearance.

[Purpose of invention]

This idea is for something that is about to put a shade on,
To provide a lighting fixture which does not come off easily even when an external force is applied to the shade, can ensure the strength of the brim, has excellent heat dissipation properties, and can improve the beauty of the fixture.

[Disclosure of invention]

The lighting device of this invention surrounds and holds a downward-facing lamp socket, forms a collar for placing a shade on the lower end side, forms an upwardly protruding receiver on the edge of the collar, and further includes a plurality of radiation holes in the collar. a socket cover formed with a socket cover, and a fitting cylinder protruding downward from a central portion that fits inside the receiver cylinder and reflects light that has passed through the heat radiation hole from the lamp attached to the lamp socket onto the surface of the socket cover. It is equipped with a shade.

According to the configuration of this invention, since the receiver is formed on the edge of the brim and the fitting tube that fits into the receiver is formed on the shade, the strength of the brim can be increased, and the shade can be made difficult to come off. Since a plurality of heat dissipation holes are formed in the brim, heat dissipation is improved, and the lamp light emitted from the heat dissipation holes is reflected on the fitting tube to illuminate the socket cover almost uniformly, so that the appliance can be made to look beautiful.

The first embodiment of the present invention is shown in Fig. 2 to Fig. 4. That is, this lighting fixture has a ceiling hook cap 10 connected to the upper end of a cord 9,
An angle 12 is attached to the lower end of the cord 9 via a connecting metal fitting 11, a switch 13 is provided on the side of the angle 12, a socket cover 14 is attached to the lower end of the angle 12, and a lamp socket 15 is provided inside the socket cover 14. A flange 16 for mounting a shade is provided at the lower end of the socket cover 14, and the flange 1
A receiving tube 17 of a prescribed height is formed on the periphery of the angle 12. A plurality of arc-shaped heat dissipation holes 18 are formed in the flange 16 as shown in Fig. 4, and screws 19 are inserted between the heat dissipation holes 18 and a reflector 21 is screwed to the screws 19 via gaps 20. The shade 22 has a hole 23 in the center and a fitting tube 24 is hung down integrally from the edge of the hole. A lower cover 2 is formed so as to surround half of the angle 12 and the socket cover 14.
The lower end of the cover 25 is placed on the flange 16, and the upper cover 26 is fitted onto the lower cover 25. Notches 27, 27' for a switch are formed at the joint. Reference numeral 28 denotes a lamp, 29 denotes a ceiling hook body, and the arrow denotes a light beam.

With this configuration, this lighting fixture has the following effects. That is, (1) the fitting tube 2 of the shade 22 is attached to the receiver tube 17 of the collar 16;
Since the shade 22 is configured to fit together, it will not come off unless the shade 22 is raised to a height twice the height B of the receiving tube 17, making it more difficult to come off than before.
In addition, the strength of the collar 16 is increased by the receiving tube 17,
The shade 22 has good stability. Since the receiver tube 17 is hidden by the shade 22, the appearance is not spoiled.

(2) Since the heat radiation hole 18 is formed in the brim 16, the hot air that accumulates around the lamp base escapes through the heat radiation hole 18, reducing the temperature of the lamp base, and the lamp light emitted from the heat radiation hole 18 is reflected off the fitting tube 24. The bounced light illuminates the surfaces of the lower cover 25 and the upper cover 26 almost uniformly without casting a shadow on the part where the heat dissipation hole 18 is not opened, so that the beauty of the appliance can be created. Also, the fitting tube 2
4 and the receiving tube 17, the larger the height, the larger the reflection area of light, and the more convenient it is to make it difficult for the shade 22 to pass through.

(3) Since the reflector 21 is provided in addition to the shade 22, glare is cut compared to the case without the reflector 21, and the table surface can be brightened with less electric power. In other words, since the light is dispersed with only a shade, not only will the necessary brightness not be obtained on the table surface, but when you try to obtain the desired brightness, when you sit on the chair at the table,
This is because the lamp is visible slightly above the eyes, so the glare is strong.

(4) Since the cover is separated into an upper cover 26 and a lower cover 25, it is easy to assemble the cover.

A second embodiment of this invention is shown in FIGS. 5 and 6. That is, in the first embodiment, this lighting fixture has a heat dissipation hole 18 at the lower end of the lower cover 25'.
A notch 30 is formed at a position between the upper cover 26' and an inverted conical part 31 is formed at the lower end of the upper cover 26' to support the upper end of the socket cover 14.
A gap 33 is formed between the socket cover 6' and the lower cover 25', the notch 30 is used as an inlet, the space between the socket cover 14 and the lower cover 25' is used as a flow passage 32, and the inverted conical part 31 is used as a guide. A heat radiation path is formed using the gap 33 as an outlet, and the socket cover 14
The aim is to dissipate heat. In this case, the notch 30 is hidden by the receiver tube 17 of the collar 16, so that the appearance is not impaired, and the gap 33 between the upper cover 26' and the lower cover 25' is also not impaired by the inverted conical portion 31.

[Effect of idea]

As mentioned above, according to the lighting equipment of this invention,
A receiver is formed on the edge of the brim and a fitting tube that fits into the receiver is formed on the shade, increasing the strength of the brim and making it difficult to remove the shade.In addition, multiple heat dissipation holes are formed in the brim. This improves heat dissipation, and the lamp light emitted from the heat dissipation hole reflects off the fitting tube and illuminates the socket cover almost uniformly, giving the appliance a more aesthetic appearance.
