<P>PROBLEM TO BE SOLVED: To provide an LED lighting device and a heat-dissipation watertight cover for the same provided with an extremely excellent mechanism for rain-proofing/waterproofing and heat convection, capable of satisfying a functional requirement of heat dissipation and waterproofing. <P>SOLUTION: The LED lighting device includes lighting structure and a heat-dissipation watertight cover. The lighting structure includes LED module, and the heat-dissipation watertight cover covers the LED module. The heat-dissipation watertight cover includes a plurality of drainage strips, and among those, an air gap is formed among the adjoining drainage strips. The heat dissipation efficiency of the LED module is increased by utilizing air convection, and the infiltration of rainwater or the like can be prevented since the adjoining drainage strips have overlapping portions. <P>COPYRIGHT: (C)2010,JPO&INPIT |
