Title:
LIGHTING FIXTURE
Document Type and Number:
Japanese Patent JP2011096384
Kind Code:
A
Abstract:

To provide a lighting fixture capable of preventing a lamp pin from coming off from a lamp socket due to turning of a double spiral fluorescent lamp.

In the fluorescent lamp 20 having a spirally turned arc tube 22, a lamp pin 21 of a base 23 fitted at either end part is retained by a lamp socket 17, and the arc tube 22 is retained by a lamp support spring 18 mounted on a fixture body 12. At this time, the lamp support spring 18 is arranged in an area 26 with the adjacent arc tube 22 opposed, and retains at least either of adjoining arc tubes 221 or 222. With this, for an instance, when an outer side surface of the inside tube 222 out of the adjoining arc tubes 221, 222 is retained, the lamp pin 21 of the fluorescent lamp 20 turns to a direction of coming off from the lamp socket 17 so as a radius from the center of the fluorescent lamp 20 to tend to get larger, thus, turning is inhibited by the lamp support spring 18 to prevent the lamp pin 21 from coming off from the lamp socket 17.
