Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting fixture in which a holder body holding a ring-shaped lamp is detachably attached to a fixture body.

[0002]

2. Description of the Related Art Conventionally, a lighting fixture of this type is provided with a groove-shaped holder mounting portion in the main body of the fixture, and a horizontally long holder body is detachably mounted in the holder mounting portion.

The holder body is provided with a lamp socket for connecting the base of a ring-shaped lamp at one end and a lamp holder for holding the ring-shaped lamp at the other end, and the lamp socket is mounted on the upper surface when the holder is mounted on the holder mounting portion. A connector for electrical connection is provided on the instrument body side.

[0004]

However, in the conventional structure, the holder mounting portion and the holder body are formed in a 180 ° rotationally symmetrical shape, and the holder mounting portion is erroneously placed in the opposite direction. There is a problem that it is easy to wear.

Further, the connector is provided at one end side of the holder body having a short connection distance with the lamp socket, and when the holder body is inserted into or removed from the holder mounting portion,
There is a problem that the holder body is likely to be inclined with respect to the holder mounting portion due to the resistance force when the connector is inserted into and removed from the connector mounting portion of the holder mounting portion, and the operability of inserting and removing the holder body is poor.

Further, when a plurality of ring-shaped lamps are held in the holder body, since the lamp sockets of the ring-shaped lamps are provided only at one end of the holder body, the bases of the ring-shaped lamps are arranged in one direction, and the direction thereof is set. There is little light irradiation to the surface, and there is a problem in making the light irradiation uniform.

Further, since the starting capacitor used when the ring lamp is lit is built in the instrument body side, a connection line for connecting the starting capacitor is required for the connector connection between the instrument body side and the holder body. There is.

Moreover, in a lighting fixture in which a holder body holding a ring-shaped lamp is detachably attached to the body of the fixture, conventionally, only two ring-shaped lamps are held in the holder body, and three or more ring-shaped lamps are held in the holder body. In order to hold the lamp, it is necessary to manufacture a dedicated lamp holder for holding each ring lamp.

The present invention has been made in view of the above points, and it is possible to prevent erroneous mounting of the holder body, improve the operability of inserting and removing the holder body, and make the light irradiation uniform. The purpose is to reduce the connection line of the starting capacitor and to use the existing lamp holder.
