<P>PROBLEM TO BE SOLVED: To provide an LED lamp capable of immediately and efficiently dissipating the heat generated. <P>SOLUTION: The LED lamp includes a plurality of substrates 2 formed in parallel as a multi-stage layer, and a plurality of LED modules 1a each containing an LED array and a multi-tip LED array thermally coupled with each other. Each substrate 2 is thermally coupled to at least one heat dissipation device 3, a transparent cover 4 attached at a front of an LED lamp 100, and a lamp shade 5 fixed at a rear site of the LED lamp 100 and coupled to an inner side site of the heat dissipation device 3. The substrate 2 is housed between the transparent cover 4 and the lamp shade 5. The heat dissipation device 3 includes a plurality of heat transmission blocks 31, a plurality of horizontal heat pipes 32, a plurality of vertical heat dissipation fins 33, a plurality of vertical heat pipes 34 and a plurality of horizontal heat dissipation plates 35. <P>COPYRIGHT: (C)2010,JPO&INPIT |
