JP 2002-260433 A (FIG. 1, claim 1)

Usually, an adapter is used to change the mounting dimensions in order to use one socket with socket bases having different mounting dimensions.
However, in recent years, lighting fixtures that can commonly use straight tube fluorescent lamps having different lamp diameters have been developed, and thus adapters for increasing the lamp height have become necessary.
By the way, in the adapter set disclosed in Patent Document 1 above, the socket base has a U-shaped slit toward the lamp mounting direction, and is pushed from the straight tube fluorescent lamp on one surface of the center of the U-shaped slit. It is designed to receive pressure. Therefore, in order to receive the pressing force from the straight tube fluorescent lamp, the adapter is mounted on the adapter from the same direction as the lamp insertion direction.
However, since the straight tube fluorescent lamps having different lamp diameters have the same length, the interval between the opposed sockets cannot be changed. Therefore, a member that narrows the interval between the sockets cannot be inserted between the socket back surface and the socket base. Therefore, a method of mounting the adapter from the lamp mounting side of the socket can be considered.
In this way, if the adapter does not change in height from the socket base of the socket, the load from the lamp applied to the socket is directly applied to the socket base that abuts, so there is no problem such as the socket coming off the adapter. .
However, when changing the height of the socket, there is a risk that the socket rear surface and the socket base will not come into contact with each other, and the socket may come off or the mounting groove may be damaged.

  The present invention has been made to satisfy the above-mentioned demand, and its purpose is to reduce the load resistance of the socket for the straight fluorescent lamp even if the height relationship between the socket for the straight fluorescent lamp and the socket base changes.
