<P>PROBLEM TO BE SOLVED: To provide a light emitting diode lamp (LED) which makes distribution of temperature in a cabinet to be uniform even when a plurality of LED lamp units are installed in positions shifted vertically. <P>SOLUTION: The LED lamp 10 contains the cabinet 11 with an open front, a plurality of LED lamp units 12 each provided with at least one LED element installed in positions shifted vertically so that the light is irradiated toward the front of the cabinet, a front lens 13 composed of translucent material closing the open front surface of the cabinet. The LED lamp 10 is composed of thermally conductive members 14 and 15 made of high temperature conductive material installed above and below the LED lamp units and a connecting member 16 made of a high temperature conductive material thermally connecting the top and bottom thermally conductive members. <P>COPYRIGHT: (C)2007,JPO&INPIT |
