Abstract

PURPOSE:To prevent a lamp from falling off even when it is detached from a socket so as to enhance the safety by attaching/detaching a long and narrow lamp holder to/from the main body of the lighting fitting, the lamp holder having a lamp socket and a lamp engagement portion both of which receive respective annular lamps from above. CONSTITUTION:Annular lamps 22, 23 are held from almost above the holding portions 28, 31, 32, 33 of a lamp holder 21 and are mounted to respective lamp socket portions 27, 30 from almost above, so that the lamps 22, 23 will not fall off even when detached from the respective socket portions 27, 30. In the case of exchanging the lamps 22, 23, the control piece portion 35 of the holder 21 is pushed from a control portion 15 to release locking of a locking piece portion 34 with a locking hole 6, and the holder 21 is detached from the engagement recessed portion 5 of the main body 1 of the lighting fitting and is carried to a desired place so as to simplify exchanging work. Moreover, because the lamp 22 with larger diameter is located on the lower side when the holder 21 is held by a hand, it is stably placed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) The present invention relates to a lighting device, and relates to a device such as a pendant that is provided with a removable lamp holder for attaching a lamp to the main body of the device.
