<P>PROBLEM TO BE SOLVED: To provide an LED lamp that is loaded instead of a conventional fluorescent lamp and is capable of adjusting radiation direction to a desired one. <P>SOLUTION: In the LED lamp 1, movable caps 12 and 13 of caps 3 and 4 attached to a tube end 2a of a lamp tube 2 are rotatable around the central axis line of the lamp tube 2. When the movable caps 12 and 13 are rotated, an LED board 7, along with a pair of terminal pins 5a-6b attached thereto, rotates around the central axis line in the lamp tube 2. As a result, the radiation direction of an LED8 loaded on the LED board 7 changes. When loading the LED lamp 1 on a socket for loading instead of a conventional fluorescent tube, the rotational direction of the LED lamp 1 can be adjusted to the desired direction by rotating the movable caps 12 and 13. <P>COPYRIGHT: (C)2010,JPO&INPIT |
