Description

[Detailed description of the invention] Industrial field of application This invention relates to a lighting fixture for annular fluorescent lamps, which are used for indoor lighting in ordinary homes.

Prior Art A conventional general example of a ceiling-suspended lighting fixture for two annular fluorescent lamps will be explained with reference to FIG. 1.
is a circular sheet metal device body, and has an inverted dish-shaped upper cover 1a with a stabilizer (not shown) attached to the bottom surface.
and a dish-shaped lower cover 1b, which also serves as a reflector, are stacked and screwed together to form an integrated structure. 2, 2, .
Three lamp holders for two circular fluorescent lamps made of metal or resin are fixed in place with screws 3, 3... and extend downward, and 4, 5 are held by each lamp holder 3, 3... It is a two-light annular fluorescent lamp. Reference numeral 6 denotes a resin-molded shade placed on the flange portion 1' of the instrument body 1 and surrounding the annular fluorescent lamps 4 and 5.

The packaging of such a luminaire for annular fluorescent lamps is carried out in accordance with the method of selling the luminaire. A packaging method in which the instrument unit 8 and the shade 6 are stored and sealed in two bottomed box-shaped cases, a separate packaging method in which the instrument body unit 8 and the shade 6 are separately stored and sealed in their respective bottomed box-shaped cases, or separate packaging methods. and the instrument body unit 8 and shade 6
There are also blister packs of each.

Problems to be Solved by the Invention In packaging the above-mentioned lighting fixtures, if the lamp holders 2, 2... are removed from the fixture body 1 and then packed, the user of the lighting fixture can attach the lamp holders 2, 2... to the fixture body 1 after purchasing the lighting fixture. Since the annular fluorescent lamps 4 and 5 must be assembled by screwing them together, the commercial value of the lighting equipment will be lost. Therefore, the above-mentioned lighting equipment is packaged with the lamp holders 2, 2, . . . attached to the equipment main body 1, but this has the following problem.

First, when storing and packing the instrument body unit 8 and the shade 6 in one case, the annular fluorescent lamps 4 and 5 on the instrument body unit 8 side should not hit the shade 6 or the case. Spacers are required to protect the lamps 4 and 5, which increases the amount of packaging materials and the number of man-hours required for packaging, resulting in an increase in packaging costs.

Second, in the case of packaging the appliance body unit 8 in separate packaging, since the lamp holders 2, 2, etc. protrude from the appliance body 1, the appliance body unit 8
This increases the bulk of the product, making it difficult to package it compactly and save on packaging materials, and, similar to the first problem above, requires a spacer to protect the annular fluorescent lamp.

Thirdly, even when the appliance body unit 8 and the shade 6 are packed separately in blister packs, the appliance body unit 8 is bulky, so a problem similar to the second problem arises.

Means for Solving the Problems The present invention was made in view of the above-mentioned problems in packaging, and it is designed to house circuit parts such as ballasts, and to package a device body having a flange portion and a lamp from above and from the side. In a lighting device comprising a cover and a shade having a top plate portion to which a flange portion of the device body is locked, a lamp holder is integrally attached to the lower surface of the top plate of the shade, and the device body and the lamp storage are connected. It is made separable into shades.

Function: By fixing and integrating the lamp holder with the shade as in the above method, it is possible to attach an annular fluorescent lamp to the lamp holder and to package the annular fluorescent lamp in a manner that protects the annular fluorescent lamp with the shade. The spacer for protecting the light lamp can be omitted or the size can be reduced. Particularly in the case of packaging by shade, it is possible to pack the instrument body alone, and a significant reduction in packaging costs can be achieved. Further, in the case where the shade and the lamp holder are integrally molded from resin, the lamp holder assembly work can be omitted from the production of the lamp holder alone or the lighting equipment assembly process.
