Description

  The present invention relates to a lighting device, and more particularly to a sliding structure of a socket cover.

  A lighting device using a straight tube lamp such as a fluorescent lamp is provided with a socket for mounting the straight tube lamp. The terminals at both ends of the lamp are inserted into the socket, and electricity is supplied to the lamp from the socket, and the lamp is turned on. The socket is provided with a socket cover for protecting the socket, protecting the appearance and preventing the lamp from falling off, and covers the periphery of the socket and the end of the lamp. When installing or removing the straight tube lamp from the socket, shift the socket cover and work so that the terminals of the straight tube lamp can be removed from the socket.

  In the related art, there is known a structure in which a socket cover has a slidable structure. A pair of locking projections are provided on the socket cover, and the locking projections are fitted into locking recesses provided on the guide ribs that guide the respective locking projections, thereby restricting the movement of the socket cover. The locking projection is made detachable by the elasticity of the socket cover, and is detached from the locking recess by gripping the side wall of the socket cover, so that the socket cover is slidable. Further, when the socket cover slides, the locking projection slides along the inner surface of the sliding recess of the guide rib due to the elastic force of the side wall of the socket cover (for example, see Patent Document 1).
