Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to shades for lighting fixtures, and more particularly to square shades for annular fluorescent light fixtures.

Unlike the round shade, the square shade of conventional annular fluorescent lamp fixtures cannot rotate and lock the lower shade to the upper and lower halves, which are divided into upper and lower halves. A rectangular shade was formed by connecting the four corners using decorative parts, or by making the open ends of the upper and lower halves of the shade parts face each other and joining them using a decorative band to form a rectangular shade. For the rectangular shade that is divided into two in the vertical direction, the parts must be manufactured using a large injection molding machine.
A rectangular shade that is divided has a large number of parts, and a large number of man-hours are required to assemble them.

In addition, a rectangular shade that is divided into two halves (top and bottom) requires a movable mechanism for the decorative band that connects the halves, which takes a lot of man-hours to manufacture. In any of the above methods, the manufacturing cost of rectangular shades is higher than that of round shades. The disadvantages are that they are large, require a lot of inventory space, and have high transportation costs.

In order to manufacture a rectangular shade at low cost and to reduce transportation costs, the shade of the lighting equipment according to the present invention is constructed by locking the upper and lower shades at the open ends without using separate parts, and A feature of this product is that the shade and the junior officer can be separated and packaged by overlapping each other.

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a plan view of an annular fluorescent lamp device with a shade attached thereto according to the present invention, FIG. 2 is a side view of the annular fluorescent lamp device with the seventh section cut away, and FIGS. 3 and 4 are respectively A sectional view showing an upper shade and a lower shade.

FIG. 5 is a sectional view showing the packaged state of the annular fluorescent lamp device. As shown in FIGS. 1 and 2, the rectangular shade according to the present invention has an upper shade 1 attached to a main body 2 of an annular fluorescent lamp apparatus.
It is fitted into a collar 4 protruding from the outer periphery of the main body 2 of the instrument, and is protruded from the outside of the lower opening end of the seventh door 1. A ring-shaped fluorescent lamp 8 mounted on the instrument body 2 is covered by locking the groove 7 provided along the . That is, the upper shade 11'i, which has a nearly vertical rising wall and a square opening end, is molded from synthetic resin, and the instrument body 2 is inserted into the center of the upper surface.
Provided with an upper hole 3 that can be engaged with a collar 4 protruding from the outside of the
A protrusion &5 is provided protruding from the outer periphery of the lower opening end. A lower shade 6 made of synthetic resin and having an outer shape approximately 4'll similar to the shade 1 above has an upper open end with an inner circumference slightly larger than the outer circumference excluding the protruding edge 5 at the open end of the upper shade 1. A groove 7 for engaging the protruding edge 5 is provided inward along the outside of the opening end, and a pilot hole larger than the upper hole 3 is provided in the center of the lower surface so that the annular fluorescent lamp 8 can pass through. 9 is provided.

The lower shade 6 and the upper shade 1 can be easily engaged or removed by bending the lower end corner portion of the upper shade 1 by utilizing the elasticity of the synthetic resin.

When packaging an annular fluorescent lamp device to which a rectangular shade according to the present invention is attached, after removing the lower shade 6 and the upper shade 1 from the appliance body 2, place the shade at a predetermined distance from the bottom of the packaging box 10. Place the upper shade 1 on top of the abutment 11 with the open end facing up, inside the lower shade 6, and place the annular fluorescent lamp 8 on the abutment 11 with the protruding part of the instrument body 2 attached with the annular fluorescent lamp 8 facing down. Insert the cylindrical attachment 12 of the specified size into the hole provided in the center of the annular fluorescent lamp 3.
The lower end of the container 1 is brought into contact with the collar 4 of the instrument body 2, and the lid of the packaging box 1 is closed. If it is packaged in this manner, the periphery of the upper hole 3 of the upper shade 1 is pressed against the base 11 within the pilot hole 9 of the lower seven-door 6 using the four flanges protruding from the main body 2 of the instrument, and the lower shade is fixed. 61d:
Since it is sandwiched between the upper shade 1 and the support 11 to prevent it from shaking, the shade can be transported safely without being damaged. By packaging the shade, the volume of the packaging box can be reduced to about 3/4 compared to when the shade is packaged in an assembled state.

The shade of the lighting equipment according to the present invention has a rectangular shade divided into upper and lower parts, each of which has a protruding edge and a locking groove at its open end.
It does not require any parts (it has a structure that allows the upper and lower shades to be locked or removed, so it can be manufactured at low cost,
Also, since the lower shade is provided with a locking groove, the joint between the upper and lower shades is not visible during use. Furthermore, when packaging, place the upper shield on top of the lower shield with the open end facing up, and secure by pressing with the brim of the device itself.
This eliminates the need for packaging accessories to prevent movement of the shade, reduces the volume of the packaging box, reduces inventory space, and greatly reduces transportation costs.
