<P>PROBLEM TO BE SOLVED: To provide at low cost a simple-structured lighting fixture capable of utilizing an LED bulb excellent in durability performance and energy-saving performance in place of a fluorescent tube of a fluorescent lamp. <P>SOLUTION: A plurality of LED bulbs 19 are fitted each on a plurality of bulb fitting units 18 each arranged on a fixing board 13. Each of the bulb fitting units 18 engages an electrode socket inside an upper part of a socket fixing cylinder which is fixed on a hole 17 of the fixing board 13 and projects upward of the fixing board 13, and the electrode socket is positioned at the upper part of the socket fixing cylinder and locked by a locking means. The LED bulb 19, in a state of a bulb base part being connected with the electrode socket, keeps a bulb heat radiation part in a non-contact state with an entire circumferential space interposed against a lower edge opening of the socket fixing cylinder, and a bulb light-emitting part is projected downward of the socket fixing cylinder. <P>COPYRIGHT: (C)2012,JPO&INPIT |
