Description

Detailed Description of the Invention [Objective of the Invention] (Industrial Field of Application) The present invention relates to a lighting fixture, such as an open-bottom ceiling-embedded lighting fixture that has an illumination opening at the bottom. The present invention relates to lamp sockets that are equipped with socket covers that cover lamp sockets.

(Prior art) In conventional lighting equipment of this type, the
As shown in the figure, a pair of lamp sockets 3 are attached to both ends of the device main body 2, which has a irradiation amount [-1 part 1 formed on the lower surface.
A structure is known in which the lamp socket 3 exposed on the lower surface of the appliance main body 2 is covered with a cover 4. This conventional socket cover 4 has a lamp insertion hole 5 through which the base of a straight tube lamp is inserted, and is formed continuously with a front part 7 that covers the lamp mounting surface 6 of the lamp socket 3. An abbreviated cover plate 9 consisting of a lower surface part 8 that covers the lower surface of the lamp socket 3 is provided, and a lower end fixing part 11 of a metal fitting 10 is fixed with a screw 12 to the inside of the lower surface part 8 of this cover plate 9. However, for this attachment, a structure was adopted in which an engaging part 13 formed on the upper part of the metal fitting 10 was engaged with the upper edge of a reflecting plate 14 attached to the instrument main body 1 with screws.

Furthermore, a structure in which a socket cover is directly screwed to a lamp socket is also known.
