[0005] Accordingly, an object of the present invention is to provide a lighting fixture capable of reducing the operating force when attaching and detaching a lamp.

[0006]

The lighting fixture of the present invention is:
An orientation control member that has a mounting spring on its back surface for detachably holding the one-base lamp and that covers the front surface of the one-base lamp; and an orientation control member that is rotatable in a direction intersecting the direction of engagement and disengagement of the orientation control member. A device body having a one-sided lamp socket and having a support arm provided at a tip end with a support spring for holding the one-sided lamp so as to be detachable in a rotation direction of the one-sided lamp socket. It is.

[0007]

According to the structure of the present invention, the lamp pin of the one-base lamp is inserted into the one-base lamp socket, the one-base lamp is rotated to be held by the support spring, and the mounting spring of the orientation control member such as the cover is mounted. The orientation control member is mounted on the front side of the one-base lamp while being held by the one-base lamp. In this case, since the direction in which the one-base lamp is disengaged from the support spring of the support arm intersects with the direction in which the one-base lamp mounting spring is disengaged, the one-base lamp is supported by the support spring even when the orientation control member is removed in the direction. Since it is not the direction in which the lamp is disengaged from the support spring, it is possible to prevent the one-base lamp from coming off from the support spring, and therefore, the spring force of the support spring can be weakened, so that the operating force for attaching and detaching the one-base lamp can be reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS. That is, this lighting fixture includes a fixture main body 1,
An orientation control member 2. The orientation control member 2 has a mounting spring 7 on the back surface for holding the one-base lamp 4 in a detachable manner, and covers the front surface of the one-base lamp 4. The orientation control member 2 of the embodiment is a cover, and has a pair of mounting springs 7 mounted on the inner surface thereof upward. The mounting spring 7 includes a pair of holding pieces 12 held by one of the glass tubes of the one-base lamp 4, and is mounted on the orientation control member 2 via the mounting pieces 15. The direction of engagement and disengagement of the orientation control member 2 is perpendicular to the one-base lamp 4 in the horizontal posture, and the operating force is caused by the spring force of the pair of mounting springs 7.

The fixture body 1 includes a one-piece base lamp socket 3 that is rotatable in a direction intersecting the direction in which the orientation control member 2 is engaged and disengaged.
And a support arm 6 provided at a distal end thereof with a support spring 5 for holding the one-base lamp 4 so as to be detachable in the rotation direction of the one-base lamp socket 3. In the embodiment, as shown in FIG. 3, the upper end surface of the appliance body 1 is attached to the ceiling 8 and the direction of rotation of the one-base lamp socket 3 is horizontal. And the support springs 5 are horizontally oriented. A known means such as a shaft and a bearing is used as a rotating means of the one-base lamp socket 3. The one-base lamp 4 has a structure in which a pair of glass tubes that are long in the horizontal direction are arranged vertically in parallel, an electrode is provided at a base end portion, and a tip end portion is connected by a connecting portion (not shown). Further, the supporting spring 5 is composed of a pair of holding pieces 9 and 10 held by the two glass tubes of the one-base lamp 4. When the one-base lamp 4 is connected to the one-base lamp socket 3, the lamp pin of the one-base lamp 4 is inserted into the one-base lamp socket 3, and then the one-base lamp 4 is rotated to support the one-base lamp 4. Hold on to 5. Conversely, when removing the one-base lamp 4, the one-base lamp 4 is rotated to remove it from the support spring 5, and then the lamp pin is pulled out from the one-base lamp socket 3. In this case, the operation force for attaching and detaching the one-base lamp 4 depends on the spring force of the support spring 5. The direction in which the attachment spring 7 of the orientation control member 2 is engaged and disengaged is perpendicular to the horizontal direction in which the support spring 5 is engaged and disengaged. Even if the spring force of the support spring 5 is weak, the one-base lamp 4 does not come off from the support spring 5.

According to this embodiment, the lamp pin of the one-base lamp 4 is inserted into the one-base lamp socket 3, the one-base lamp 4 is rotated to be held by the support spring 5, and the orientation control member 2 such as a cover is provided. The orientation control member 2 is attached to the front side of the single-base lamp 4 by holding the mounting spring 7 of the single-base lamp 4.
In this case, since the direction of engagement / disengagement of the one-sided lamp 4 from the support spring 5 of the support arm 6 intersects with the direction of engagement / disengagement of the mounting spring 7 of the one-sided lamp 4, even if the orientation control member 2 is pulled in the disengagement direction. Since the one-base lamp 4 does not move away from the support spring 5, the one-base lamp 4 can be prevented from coming off the support spring 5, and the spring force of the support spring 5 can be reduced. Operating force can be reduced.

Although the orientation control member 2 is a translucent cover in the embodiment, it may be a louver. Further, in the embodiment, the glass tubes of the one-base lamp 4 are arranged vertically, but the glass tubes may be arranged horizontally like FIG. The mounting direction of the mounting spring 7 is perpendicular to the supporting spring 5, but it is not necessarily required to be a right angle. If the mounting range A intersects as shown in FIG. Can be mounted because it is difficult to remove. In this case, it is preferable that the direction of engagement and disengagement of the orientation control member 2 is perpendicular to the mounting surface such as the ceiling 8 of the appliance main body 1 and the direction of rotation of the one-base lamp 4 crosses the mounting surface non-perpendicularly. .

[0012]

According to the luminaire of the present invention, the direction of engagement and disengagement of the one-base lamp from the support spring of the support arm intersects with the direction of engagement and disengagement of the mounting spring of the one-base lamp. Pulling in one direction does not cause the one-sided lamp to come off the support spring, so that the one-sided lamp can be prevented from coming off the support spring, and the spring force of the support spring can be weakened. There is an effect that the operating force can be reduced.
