<P>PROBLEM TO BE SOLVED: To provide an LED lamp that is so structured as to efficiently radiate heat generated in an LED lamp unit to the outside and to secure movability of the LED lamp unit. <P>SOLUTION: This LED lamp 10 includes: a casing 11 having an opened front side; one or more LED lamp units 12 arranged so as to emit light toward the front side in the casing; a front lens 13 formed of a translucent material closing the opened front face of the casing; and a heat radiation member 14 formed of a heat conducting material with the LED lamp unit(s) attached and thermally connected thereto. The LED lamp 10 is so structured that the heat radiation member 14 is formed into a hollow cylindrical shape and arranged in the casing; and its upper and lower ends are airtightly connected to through-holes 11a and 11b formed on the upper surface and the lower surface of the casing by sealing members 15a and 15b, respectively. <P>COPYRIGHT: (C)2007,JPO&INPIT |
