<P>PROBLEM TO BE SOLVED: To provide a lighting fixture achieving that: (1) problems such as an overvoltage are not generated even if the lighting fixture is connected to a lighting fixture for a conventional fluorescent lamp; (2) an LED lamp is sealed; (3) the weight of the LED lamp can be made to be just like a weight of a conventional fluorescent lamp; and (4) even if a socket is deteriorated, this is not affected by failures such as electrical connection faults due to deterioration. <P>SOLUTION: The LED lamp 10 includes: a hollow type cylindrical body 10a of which a portion has light translucency; a substrate which is housed in the cylindrical body 10a and mounts a light-emitting element; a fixture attaching part which is installed at both end parts of the cylindrical body 10a and which fixes the LED lamp 10 to the lighting fixture; and a lamp side connecting terminal 10c which is installed on the cylindrical body 10a and connected to the substrate. A cabinet part 15 sealed up by the cylindrical body 10a and the fixture attaching part is formed. A power supply part 20 includes a power supply body 20a which converts a commercial power supply to a direct current power supply for light-emitting elements, and a power supply part side connecting terminal connected to the lamp side connection terminal 10c. <P>COPYRIGHT: (C)2012,JPO&INPIT |
