Abstract

PURPOSE:To prevent unevenness in the distribution of light and simplify exchange of lamps by integrally molding the socket arms of a lamp holder which are mounted to the lighting fitting main body in such a manner that they can be freely attached/ detached thereto/from, and molding a holding arm from translucent material independently from the holder, and mounting the arm to the holder. CONSTITUTION:A lamp holder 21 comprises a socket arm 24 integrally formed therewith and including lamp sockets 27, 30 to be electrically connected when the holder 21 is mounted to the lighting fitting main body 1, and the holder 21 also comprises a holding arm 25 mounted thereto which arm is formed from translucent material independently from the holder 21 and which has holding portions 32, 33 for holding respective annular lamps. When the lamps are lighted light will not therefore be cut off and so unevenness in the distribution of light and shadow of the arm are prevented. The holder 21 can be attached/detached to/from the main body 1 with a lamp being mounted thereto, which simplifies exchange work of lamps. Moreover, there is no necessity of performing operation of attaching/detaching lamps to the sockets, and the sockets and the holder are formed integrally with each other, whereby the number of parts is decreased and the cost reduced.

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 Publication No. 0209, a lamp socket is connected to the appliance body via a cord, and a lamp holder for holding an annular lamp is detachably attached to the appliance body. .

Furthermore, as described in Japanese Patent Application Laid-Open No. 57-126003, a structure is known in which a lamp socket is provided on the reflective surface of the main body of the device, and a lamp holder for holding an annular lamp is detachably provided on the main body of the device. ing.

(Problem 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 only holds the annular lamp;
In addition, when replacing a lamp, the lamp must be connected to and removed from the socket connected to the fixture using a cord from a high place, such as the ceiling, where the fixture is installed, resulting in poor operability. have.

Furthermore, even in the structure described in JP-A-57-126003, the lamp holder only holds the annular lamp, and when replacing the lamp, the operation of disconnecting the lamp from the socket must be done at a high place. This has the problem of poor workability.

Furthermore, in the conventional lighting equipment, the lamp holder is made of a non-transparent material, which causes unevenness in the light emitted from the annular lamp, resulting in the problem that a shadow of the lamp holder appears on the lamp.

The present invention has been made in view of the above-mentioned problems, and includes a socket arm having a socket for attaching the annular lamp to a lamp holder, and a holding arm having a holding portion for holding the annular lamp to hold the annular lamp. When the holder is attached to the fixture body and the lamp is lit, the holder arm will not block the light emitted from the lamp and will not cast a shadow on the lamp. The lamp holder can be attached to and detached from the fixture body while the lamp is still held in the lamp holder, without the need to attach or detach it from the socket.When replacing the lamp, the lamp holder is removed from the fixture body and the lamp can be replaced. To provide a lighting device that allows work to be carried out and has good workability in attaching a lamp.
