<P>PROBLEM TO BE SOLVED: To provide an LED lamp that achieves weight saving while improving heat dissipation property. <P>SOLUTION: The LED lamp includes: a longer form glass tube 3; a mounted substrate 5 including on a surface thereof an SMD LED 7 composed by sealing an LED device mounted on an element packaging substrate and provided in the glass tube 3 while bridging separated two parts on an internal surface of the glass tube 3; and an adhesive material 9 jointing the mounted substrate 5 with the glass tube 3. In the LED lamp 1, end edges extending to a longitudinal direction of the mounted substrate 5 contact with the internal surface of the glass tube 3, and the adhesive material 9 fills between a back surface of the mounted substrate 5 and the internal surface of the glass tube 3. <P>COPYRIGHT: (C)2011,JPO&INPIT |
