Description

  The present invention relates to a socket to which a straight tube lamp is mounted and a lighting fixture including the socket.

  As a straight tube lamp used for ceiling lighting or the like, a straight tube LED lamp using an LED (Light Emitting Diode) as a light source is known. Some straight tube LED lamps include a heat sink for heat dissipation on the back side of the light emitting surface. In such a straight tube type LED lamp, the side where the heat sink is arranged becomes heavy in the cross section, and thus the lamp is eccentric. As a result, when the straight tube LED lamp is mounted in the socket, if the rotation position to be mounted is not normal, the lamp rotates due to external factors such as vibration, and the lamp is not lit or dropped. There is a risk of causing it.

  Therefore, for example, Patent Document 1 proposes to provide a configuration for preventing the straight tube LED lamp from falling. Specifically, in the lighting fixture described in Patent Document 1, a hook portion having a fistula is provided in a base of a straight tube LED lamp, and a hook-like hooked portion is provided in a socket. And when attaching a straight tube | pipe type LED lamp to a socket, it has the structure which prevents fall of a straight tube | pipe type LED lamp by hooking the latching | locking part of a socket on the latched part of a lamp | ramp.
