Description

  The present invention relates to an illumination unit for mounting a straight tubular illuminating body having supported parts at both ends to a duct attached to a building (ceiling or wall).

  In recent years, since energy saving and ecological measures have been promoted, a light emitting diode (LED element) as a light source is surrounded by a transparent cylindrical body, and a straight tubular illuminating body having supported parts at both ends is attached. A device is provided. This lighting device has higher luminous efficiency than conventional incandescent bulbs and fluorescent lamps, consumes less power, and can greatly contribute to the reduction of CO2 emissions. In addition, the light source has a longer life and less replacements than conventional fluorescent lamps.

  As this type of lighting device, for example, as shown in FIG. 12, a duct 100 attached to a building (ceiling or wall) and a pair of sockets 101, 101 attached to the duct 100 are provided (see Patent Document 1). ).

  The duct 100 is formed in a long shape and has a strip-shaped opening 100a extending in the longitudinal direction. More specifically, the duct 100 has a pair of side walls 100b and 100b, and the pair of side walls 100b and 100b defines a groove. A contact groove 102 is formed in the pair of side walls 100b and 100b, and the contact 102a is disposed in the groove 102. Further, the duct 100 is formed with a pair of protruding pieces 103 and 103 that are locked by locking pieces 1013 and 1013 of a socket 101, which will be described later.

  The socket 101 includes a support part 1010 and a connection part 1011. The support portion 1010 is configured to be able to support the illumination body. The connection unit 1011 is configured to be connected to the contact 102a of the duct 100 so that power can be supplied to the terminal of the illuminating body. Specifically, the connecting portion 1011 includes a shaft 1012 inserted into the groove of the duct 100 and a pair of locking pieces 1013 and 1013 connected to the shaft 1012, and is connected to the protruding pieces 103 and 103 of the duct 100. A pair of locking pieces 1013 and 1013 to be locked and a conduction portion 1015 formed to extend parallel to the one locking piece 1013 are provided.

  According to the lighting device having such a configuration, the shaft 1012 of the socket 101 is inserted into the groove of the duct 100, the socket 101 is rotated about the shaft 1012, and the pair of projecting pieces 103 and 103 of the duct 100 are connected to the socket 101. 101 locking pieces 1013 and 1013 are locked and attached.
