Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a single-base fluorescent lamp luminaire, and more particularly to a structure for holding a single-base fluorescent lamp.

[Conventional technology]

BACKGROUND OF THE INVENTION Lighting devices such as stand-type lighting devices are known in which a single-ended fluorescent lamp as a lamp mounted in a socket provided in a lamp body is covered with a substantially cylindrical shade. FIG. 8 shows an example of such a stand-type luminaire of a single-ended fluorescent lamp luminaire. A stanchion 2'is provided on the upper surface of a base 1'in which a lighting device is installed. A lamp 4'equipped with a single base fluorescent lamp is rotatably disposed at the tip of 2'through a universal device 3 '.

In such a single-base fluorescent lamp luminaire, the lamp 4'is
As shown in the figure, an elastic locking piece provided on the fitting portion 61 'by fitting the fitting portion 61' at the base of the shade 6'into the shade receiving tool 5 '.
The projection 63 'at the tip of 62' is engaged with the recess 57 'provided on the inner surface of the shade receiving tool 5', and the shade 6'is attached to the shade receiving tool 5 ', and the shade 6'is housed in the shade receiving tool 5'. A single base fluorescent lamp 8 is attached to the lamp socket 7.

[Problems to be solved by the device]

In such a single-base fluorescent lamp luminaire, the lamp socket 7 has locking springs 71 on both upper and lower side surfaces, and the locking projections 82 projecting on both parallel side surfaces of the base 81 of the single-base fluorescent lamp 8 have the above-mentioned structure. The locking spring 71 is locked, the lamp pin of the single-ended fluorescent lamp 8 is inserted into the lamp pin insertion hole 72 of the lamp socket 7, and the single-ended fluorescent lamp 8 is attached to the lamp socket 7.

However, when the single base fluorescent lamp 8 is attached to the lamp socket 7, notches 73 are provided at both longitudinal ends of the lamp socket 7 in order to avoid protrusions at both longitudinal ends of the base of the single base fluorescent lamp. The lamp 8 sways left and right, and the tip of the single-ended fluorescent lamp 8 may hit the inner surface of the shade 6 ',
There is a problem that the single-ended fluorescent lamp 8 may be slanted with respect to the shade 6'and the appearance may be damaged.

The present invention has been made in view of the above background, and an object of the present invention is to provide a single-base fluorescent lamp luminaire capable of preventing rattling in the horizontal direction of the single-base fluorescent lamp with a simple structure. It is a thing.

[Means for Solving the Problems]

The single-base fluorescent lamp luminaire according to the present invention is mounted on the shade socket with the lamp socket facing the lamp insertion opening, and the single-ended fluorescent lamp is attached to the lamp socket by inserting the lamp insertion opening. In a single-base fluorescent lamp luminaire that is fitted with a shade to cover the single-base fluorescent lamp, use the base of the single-base fluorescent lamp installed in the lamp socket on the side where the shade and the shade receiver are fitted together. Corresponding to the pair of protruding protrusions, a locking piece made of an elastic piece is arranged so that the vicinity of the tip projects outward, and the tip of the locking piece has a shade fixing claw on the outer surface on the inner surface. On the side, the lamp fixing claws are projected respectively,
When the shade and the shade receiver are fitted, the shade fixing claw of the locking piece abuts the inner surface of the side where the shade and the shade receiver are fitted together, and the lamp fixing claw locks the single-ended fluorescent lamp. It engages with the protrusion.

〔Example〕

1 to 6 show an embodiment of the present invention, which will be described below with reference to the drawings.

This embodiment is a stand type luminaire, and a supporting column 2 is rotatably attached to a side surface of a base 1 in which a lighting device is installed, and a single-ended fluorescent lamp is attached to a tip of the supporting column 2 via a universal device 3. The light fixture 4 equipped with is rotatably arranged with respect to the support column 2.

A lamp 4 of this single-base fluorescent lamp luminaire includes a shade receiver 5 formed of elastic plastic and attached to a universal device 3.
And a shade 6 externally fitted to and attached to the shade receiver 5.

The shade receiving member 5 has a substantially rectangular box shape, and a lamp insertion opening 52 through which the base 81 of the single base fluorescent lamp 8 is inserted is formed on the front end side of the fitting portion 51 of the shade 6 on the front end side. Further, a step portion 53 with which the tip of the externally fitted shade 6 abuts is formed on the base end side of the shade fitting portion 51 of the shade receiving tool 5. Elastically deformable locking pieces 54 are integrally formed on both side surfaces of the shade fitting portion 51 so as to project outward. The tip of the locking piece 54 is fixed to the outside surface of the shade receiving device 5 by a shade. The claw 55 is provided with a lamp fixing claw 56 on the inner surface side of the shade receiving device 5, respectively. A lamp socket 7 in which a single-base fluorescent lamp 8 is mounted is housed in the shade receiver 5.

A light transmissive opening is formed on the lower surface of the shade 6 except for one end side, and an end portion where the light transmissive opening is not provided has a side surface that is fitted to the shade fitting portion 51 of the shade receiving tool 5. It is a joint 61.

In using and using this single-base fluorescent lamp illuminator, the single-base fluorescent lamp 8 and the shade 6 are mounted as shown in FIGS. 3 to 5.

First, the shade 6 is removed from the shade receiver 5, and the single-base fluorescent lamp 8 is attached to the lamp socket 7 as shown in FIG. At this time, the locking piece 54 of the shade receiving tool 5 is in a protruding state to the outside of the shade receiving tool 5 and the single-ended fluorescent lamp 8
It does not hinder the installation of the lamp into the lamp socket 7.

Next, as shown in FIG. 4, the shade 6 is put on the tip of the single-base fluorescent lamp 8 through the opening of the fitting portion 61. And
When the shade 6 is completely fitted to the shade receiver 5, as shown in FIG. 5, the shade fixing claw 55 of the locking piece 54 of the shade receiver 5 is in contact with the inner surface of the fitting portion 61 of the shade 6. , The shade 6 is attached to the shade receiver 5. In this state, the locking piece 54 of the shade receiving tool 5 is pushed inwardly of the shade receiving tool 5, and the lamp fixing claw 56 at the tip of the locking piece 54 engages with the locking projection 82 of the single base fluorescent lamp 8. The left and right rattling of the single-ended fluorescent lamp 8 is prevented.

In this single-base fluorescent lamp lighting device, the locking piece 54 for fixing the shade 6 also prevents rattling of the single-base fluorescent lamp 8, and the structure is simple and inexpensive so that the single-base fluorescent lamp 8 can be securely secured. Since the single-ended fluorescent lamp 8 can be attached and replaced only when the shade 6 is removed, it is possible to prevent the single-ended fluorescent lamp 8 from being damaged by trying to remove it.

As in the conventional example shown in FIGS. 7 and 8, when the shade is fitted in the shade receiver, the locking piece is not fitted in the shade receiver but in the fitted state of the shade and the shade receiver. It should be provided on the side of the side where you do. Also, the locking piece may be provided integrally with the shade receiver or the shade.
It may be a separate body.

[Effect of device]

The present invention is configured as described above, and the clasp of the shade holder for fixing the shade also prevents rattling of the single-ended fluorescent lamp, and the structure is simple and the single-ended fluorescent lamp can be secured at low cost. Since the conversion of the single-ended fluorescent lamp can be performed only with the shade removed, it is possible to prevent the single-ended fluorescent lamp from being damaged when it is forcibly removed.
