Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to lighting equipment, and relates to rating display for lamps used.

Conventionally, in this type of lighting equipment, the rating of the lamp used was indicated by a label attached to the surface of the cover, but this damaged the appearance and was easy to peel off due to the heat from the lamp, so it exceeded the limit. There is a risk that a lamp with a higher wattage value may be used, and furthermore, the cover has the disadvantage of being expensive because it requires many man-hours to attach the label.

The present invention has been made in view of the above points, and the rating is displayed on the sloped surface formed on the periphery of the front opening of the cover into which the lamp base is inserted, so that the rating is displayed in a place that is easy to see when the lamp is installed. is possible,
Moreover, the present invention provides a lighting fixture that can display as large a display as possible in a narrow space, can be obtained at low cost, and can improve safety.

The structure of the present invention includes a main body having a socket with an open front face, and a cover that covers the main body and has an opening facing the front face opening of the socket and having an opening in the front face for inserting the base of the lamp. The front opening of the cover has an annular sloped surface facing the lamp, the inner edge of which is slanted inward, on the periphery of the front opening, and a rating display is integrally formed on this sloped surface. be.

Next, the configuration of an embodiment of the present invention will be explained with reference to the drawings.

Reference numeral 1 denotes a main body, which is molded from an insulating material such as synthetic resin, and has a cylindrical socket 2 integrally formed at the center of the front surface and having an outer periphery concentric with the main body 1.
A lamp mounting part 3 opened at the front of this socket 2
is provided with an electrically conductive screw tube 4 into which the lamp base is screwed, and an electrically conductive elastic contact piece 5 which contacts the lamp base terminal.

Further, an annular locking edge 6 is provided on the outer periphery of the main body 1.

Further, the main body 1 is formed with a mounting hole 7 passing through the front and rear surfaces.

Next, reference numeral 8 denotes a cover, which is formed of synthetic resin or the like into a substantially truncated conical shape whose diameter gradually increases in a concave arc shape toward the rear.

This cover 8 has openings on the front and back sides, and the front opening 9 of this cover 8 is opened opposite to the lamp mounting part 3 opened on the front of the socket 2, and the base of the lamp can be inserted from this front opening 9. It is now possible to insert it.

An inclined surface 10 is formed on the periphery of the front opening 9 of the cover 8, and the inner edge thereof is inclined inward. It's summery. On the inclined surface 10 of this cover 8, there is a wattage rating display 11 of the lamp to be used, for example, "Pole light bulb up to 100W".
The display is formed integrally with the cover 8.

Further, a plurality of fitting guide pieces 13 whose tips 12 extend inward from the inner edge of the inclined surface 10 of the cover 8 are integrally projected rearward from the inner surface of the cover 8 at equal intervals in the circumferential direction. , each fitting guide piece 13
The rear edge 14 is curved in an arc toward the inner surface of the cover 8. Further, a small distance is formed between the tip 12 of each fitting guide piece 13 and the outer periphery of the socket 2.

Further, on the inner surface of the cover 8, a plurality of protruding pieces 15, for example, three pieces, are provided protruding rearward at positions equidistant in the circumferential direction and between the fitting guide pieces 13,
A locking portion 16 is formed at the tip of the projecting piece 15 and is removably locked to the locking edge 6 of the main body 1 by the elasticity of the projecting piece 15.

Next, the operation of this embodiment will be explained.

The main body 1 is fixed to a mounting surface such as a ceiling or a wall using a set screw inserted through a mounting hole 7. When the cover 8 is fitted into the socket 2 from the rear opening 17 in this state, each fitting guide piece 1 is attached to the front end of the socket 2.
The rear end edge 14 of the socket 2 is guided, and the tip 12 of each fitting guide piece 13 is fitted along the outer periphery of the socket 2. The front opening 9 of the cover 8 is the socket 2.
When reaching the front end of the main body 1, each of the locking portions 16 is locked to the locking edge 6 of the main body 1 by the elasticity of the projecting piece 15, and the cover 8 is attached to the main body 1 while covering the main body 1.

Then, by screwing the base of the lamp through the front opening of the socket 2 that faces the front opening 9 of the cover 8, the front inclined surface 10 of the cover 8 faces the lamp, and the front surface of the cover 8 The opening 9 is covered with a lamp. When this lamp is attached to the socket 2, the rating display 11 formed on the inclined surface 10 around the opening 9 of the cover 8 can be confirmed, and when the lamp is attached, the rating display 1
1 is covered with a lamp.

In addition, when removing the cover 8 from the main body 1, remove the lamp from the socket 2 and pull the cover 8 forward, the locking portion 16 will be released from the locking edge 6 by the elasticity of the protrusion 15, and the cover 8 will be removed from the main body 1. It can be removed from

In the embodiment described above, the tip locking portion 16 of the protruding piece 15 protruding from the inner surface of the cover 8 is connected to the locking edge 6 of the main body 1.
Therefore, when the fitting guide piece 13 is fitted along the outer periphery of the socket 2, there is a risk that the protruding piece 15 having the locking part 16 will come into contact with the socket 2 and be damaged. There is no protrusion 1
5 is located inside the cover 8 and is not deformed by heat from the lamp.

According to the present invention, an annular inclined surface facing the lamp is formed on the periphery of the front opening of the cover with the inner edge side inclined inward, and the rating display is integrally formed on this inclined surface. The display is located on the periphery of the front opening of the cover where the lamp is installed, and can be checked when the lamp is installed, so there is no chance of overlooking the rating display, and there is no risk of it peeling off, so there is no risk of installing a lamp that exceeds the limit. Moreover, since the rating display is formed on an inclined surface, the display area of the display surface can be expanded even in a narrow space, making the display large and easy to see, and since the rating display is covered with a lamp, the appearance can be improved.
