Abstract

PURPOSE:To improve safety by integrally installing and holding a ring lamp to a lamp holding body. CONSTITUTION:Elastic locking pieces 28 on the both sides of a lamp holding body 21 are mechanically locked by locking holes 6 of an equipment body 1, and held by a fitting recessed part 5. A connector piece 32 is passed into and connected to a connector hole 10 by the engaging guide between guide pieces 33 and guard holes 11, and the lead wires 27 of lamps 22, 23 are connected to a lighting circuit. As the lamps 22, 23 are integrated with the holding body 21, they are never fallen from the holding body 21. To exchange the lamps 22, 23, the operating piece part 29 of the holding body 21 is pushed from an operation part 12 to release the locking between the locking piece parts 28 and the locking holes 6, and the holding body 21 is removed from the fitting recessed part 5 of the main body 1, whereby the holding body can be separated from the body 1 as the lamps 22, 23 are still installed thereto, and the lamp exchange is facilitated. Hence, safety can be improved.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a lighting fixture, and relates to a lighting fixture including a removable lamp holder for attaching a lamp to a fixture body such as a pendant. 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 socket is connected to the appliance main body by a cord, so when replacing the lamp, it is necessary to The lamp holder must be removed from the fixture body after the lamp holder is disconnected from the socket, and the operation of attaching and removing the lamp holder must be done at a high place, making it difficult to operate, and the lamp holder holds the lamp from below,
There is a problem that the lamp may fall.

Furthermore, even with the structure described in JP-A No. 57-126003, when replacing the lamp, the operation of disconnecting the lamp from the lamp socket must be performed at a high place, resulting in poor work efficiency. A special lamp socket must be used, which is expensive, and there is also the problem that the lamp easily comes off and falls.

The present invention has been made in view of the above-mentioned problems, and is capable of holding an annular lamp integrally with a lamp holder, eliminating the risk of the lamp falling, and eliminating the need to provide the lamp with a base having a connecting bottle. Since the lamp holder is also replaced when the lamp is replaced, a material with low weather resistance can be used, thereby providing a lighting fixture that can be obtained at low cost.

[Structure of the invention]

(Means for Solving the Problems) A lighting fixture of the present invention includes a fixture body, a lamp holder mechanically and electrically detachably attached to the fixture body, and an annular lamp held in the lamp holder. The lamp holder is characterized in that the annular lamp is integrally attached and held to the lamp holder.

(Function) Since the lighting fixture of the present invention has an annular lamp attached and held integrally with the lamp holder, the lamp can be attached to the fixture body by attaching the lamp holder holding the lamp to the fixture body. At the same time, the lamp is electrically connected to the fixture body, so there is no risk of the lamp coming off the lamp holder and falling.Furthermore, since it does not require a lamp socket, it can be used in high places without having to connect the lamp socket. Lamps can be replaced by simply removing the lamp holder from the fixture body, and since the lamp and lamp holder are integrated, the lamp holder must be replaced when replacing the lamp, so the lamp holder can be replaced with a non-weather-resistant material. can be formed and obtained at low cost.

(Example) The configuration of an embodiment of the present invention will be described with reference to the drawings.

Reference numeral 1 denotes a main body of the device, which is composed of a plate-shaped base plate 2 with an opening at the bottom and a cover 3 having a substantially spherical arc surface.The outer surface of this cover 3 is, for example, a white diffuse reflection surface or a silver diffuse reflection surface It is formed on a reflective surface 4 such as a surface. And this reflective surface 4

Further, a connector hole IO is formed on the other side of the inner bottom surface of the fitting recess 5. Furthermore, guard holes 11 are formed facing both sides of this connector hole 10, respectively. Further, a semi-circular concave arc-shaped operating portion 12 is formed at the outer edges of both sides of the central portion of the lamp holder fitting recess 5 formed on the outer surface of the cover 3.

Further, a circuit board (not shown) is attached to the inner surface of the cover 3, the pull switch is attached to the approximate center of this circuit board, a connector is attached to this circuit board, and a stable Lighting parts such as containers are attached.

With this circuit board fitted into the cover 3, the lower part of the pull switch is arranged in the pull switch fitting protrusion 7, and the pull string 8 of the pull switch is inserted through the lower surface insertion hole 9 of the fitting protrusion 7. The connector is pulled out from the insertion hole 9, and the lower surface of the connector is exposed to the inside of the connector hole 10.

Next, reference numeral 21 denotes a lamp holder that is fitted into the fitting recess 5 of the instrument main body 1. This lamp holder 21 is formed into a substantially elongated shape, and the upper surface of both ends has annular shapes with different diameters. Holding arm 2 that integrally holds the lamp 22, 23
4.24 is formed to be inclined downwardly toward the outside, and both of the holding arms 24.24 are divided into upper and lower halves 25.2.
6, and these members 25 and 26 sandwich and hold the large-diameter lamp 22 on the lower side and the small-diameter lamp 23 on the upper side.

Then, a lead wire 27 connected to the filament is led out from both ends without providing a base having a connection bottle at the opposite ends of the lamps 22.2.
Both ends where the opposing lead wires 27 of No. 3 are exposed are cutout recesses 25 of the upper and lower halves 25 and 26 of one holding arm 24! , 261 are sandwiched and coated.

The lamp holder 21 also has elastic locking pieces 2 at the center of both sides that are removably locked in the locking holes 6 of the device main body 1.
8 is formed on both sides of the operation piece part 29, which is formed in the cut groove 3o, and this lamp holder 21 is inserted into the fitting recess 5 of the instrument body 1.
When fitted, the locking piece 28 is elastically engaged with the locking hole 6, so that the lamp holder 21 is attached to the instrument body 1.

From the operating section 12 of the instrument main body 1 to the central operating piece section 2
9, the locking piece 28 of the lamp holder 21 is released from the locking hole 6, and the lamp holder 21 is moved into the fitting recess 5.
It can be removed from.

Further, in the center of the lamp holder 21, an insertion hole 31 through which the pull switch fitting protrusion 7 is inserted is formed through the upper and lower surfaces. Further, on the other side of the upper surface of the lamp holder 21, a connector piece 32 is provided projectingly to be connected to the connector in the device main body 1, and this connector piece 32 is connected to the lead wire 27° 27 of the lamp 22.23. It is connected. Guide pieces 33 are provided protruding from both sides of this connector piece 32. Then, with the lamp holder 21 fitted into the fitting recess 5 of the cover 3, the pull switch fitting protrusion 7 is inserted into the insertion hole 31 and the drawstring 8 is pulled out.
Further, the connector piece 32 is inserted and connected to the connector from the connector hole 10 by being guided by the guide piece 33 and the guard hole 11.
