Abstract

PURPOSE:To improve the appearance of the lighting fitting and simplify detachment of a holder from the main body by engaging a lamp holder holding a lamp into the engagement recessed portion of the lighting fitting main body, and also providing a recessed portion for detachment at the edge of the center portion of the recessed portion. CONSTITUTION:The outside reflecting face 4 of the cover 3 of the lighting fitting main body 1 is shaped into a roughly circular face and has an engagement recessed portion 5 formed on its lower face portion in such a manner that it crosses the lower face portion in the diametral direction. The lower face portion 42 of the lamp holder 21 which is to be fitted with the recessed portion 5 is also formed as a roughly circular form in such a manner that it forms a curved face in contact with the main body when it is fitted with the recessed portion. The holder 21 is engaged by elastically locking elastic locking pieces 34 into the locking hole 6 of the main body 1, the locking pieces 34 being provided on both side faces, and is detached by pressing of the detaching control portion 35 of the holder 21 from the control recessed portion 15 of the main body 1. The holder 21 is attached/detached to/from the main body 1 as it holds a lamp, whereby the exchange work of lamps is safely and readily carried out.

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.

(Prior art) Conventional lighting equipment of this kind is, for example,
As described in Japanese Patent No. 0209, a structure was adopted in which a lamp socket was connected to a device body via a cord, and a lamp holder for holding an annular lamp was detachably attached to the device body.

Further, as described in Japanese Patent Application Laid-Open No. 57-126003, a structure is adopted in which a lamp socket is provided on the reflective surface of the device body and a holder for holding the lamp is provided.

(Problems to be Solved by the Invention) In the conventional structure described in the above-mentioned Japanese Utility Model Application Publication No. 56-130209, the lamp holder protrudes from the reflective surface of the appliance body, impairing the appearance, and making it difficult to replace the lamp. In this case, the operation of disconnecting the lamp from the socket must be performed at a high place such as on the ceiling, which poses a problem of poor operability.

Furthermore, even with the structure described in Japanese Patent Application Laid-Open No. 57-126003, the operation for disconnecting the lamp and the lamp socket must be performed at a high place, which has the problem of poor workability.

Therefore, in order to prevent the lamp holder from protruding from the appliance body, it is proposed that the lamp holder be fitted into a fitting recess formed in the appliance body so that the appliance body and the lower surface of the lamp holder are approximately flush with each other. (This is not known.) However, if the reflective surface of the device main body and the lower surface of the lamp holder are made substantially flush with each other, there is a problem that the lamp holder cannot be easily attached and detached.

The present invention has been made in view of the above-mentioned problems, and when the lamp holder is attached to the fixture body, the lower surface of the lamp holder is substantially flush with the fixture body, thereby improving the appearance. The present invention provides a lighting fixture whose lamp holder can be easily removed from the fixture body and whose lamps can be easily replaced.
