Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a multi-lamp type lighting fixture that is attached to a ceiling or the like.

[Background of the invention]

Traditionally, ceiling-mounted multi-lamp lighting fixtures incorporating multiple straight tube fluorescent lights have been used, but recently,
Design registration No. 621645, which incorporates a Jumpria-like feel, for example, incorporates multiple annular fluorescent lamps.
Multi-light lighting equipment such as No. 1 has been proposed. However, the multi-lamp type lighting equipment having such a structure is large in size, and there remain difficulties in packaging, transporting, and installing the equipment.

Furthermore, there are many constraints in terms of construction, making it difficult to design novel designs.

On the other hand, if you move the lamp body a certain distance from the center, you can get a pseudo-jump rear feeling, for example,
No. 841, Utility Model Publication No. 56-48927, or Utility Model Publication No. 55-17871, Special Publication No. 59-716 (No. 27.

The former is a screw that is attached to the tip of an arm that extends from the central base of the light body, but since it requires space above the light body for the screw fixing work, it is only possible to attach it to the ceiling. However, there are still some drawbacks to using KU as a thin multi-lamp type lighting fixture. Furthermore, even if the device is assembled on the floor and hung on the ceiling, the installation process remains difficult because the device is quite large. Furthermore, since the main parts of the latter are constructed in one piece, there remain drawbacks such as the large size of the device and the complicated assembly work.

Furthermore, Japanese Patent Publication No. 1988-88271 has been proposed as a Jumpria-type multi-lamp lighting device in which the lamp body can be freely attached and detached. This structure is convenient for attaching a light bulb-shaped light body, but if a flat light body incorporating an annular fluorescent light is available, it is difficult to align the light body. It is what it is.

[Purpose of the invention]

Therefore, we provide a multi-lamp type lighting fixture that facilitates the installation work of unexploded 8AVi.
