Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a lighting fixture using an annular lamp.

[Conventional technology]

In general, lighting fixtures using annular lamps have a leaf spring shape with a semicircular holder part at the tip that fits inside the circumferential surface of the annular lamp on the bottom surface of the fixture body, which is suspended or directly attached to the ceiling. One or more supports (in the case of multiple lights such as two lights and three lights) are installed at three locations on the same circumference, and between the holder parts of the three supports, The annular lamp is supported by the elasticity of the support.

In addition, when replacing the lamp from the appliance body due to lamp life, etc., after disconnecting the lamp terminal from the lamp socket, greatly deform the single support that supports the lamp and remove the lamp from its holder. At the same time, remove the lamp to be replaced by removing it from each holder of the other support, and then engage the new lamp with each holder of the two supports, and remove it from the holder of the other support. The support is largely deformed and engaged with its holder portion, and a new lamp is attached to the fixture body.
