<P>PROBLEM TO BE SOLVED: To provide a heat-radiating housing of an LED light that effectively reduces temperature of a light-emitting element to improve light-emitting quality, light-emitting efficiency, and service life of the light-emitting element. <P>SOLUTION: A storage hole 21 is penetrated in an axial direction of the heat-radiating housing 20 of the LED light 22. A plurality of heat-radiating fins 24 are arranged on the outer face of the heat-radiating housing along the axial direction. A plurality of parallel slots 241 are penetrated in parallel with the axial direction of the storage hole 21 in a radial direction of the heat-radiating fins 24. Both wall surfaces of the heat-radiating fins 24 are formed so as to have a predetermined contained angle. The thermal energy generated from a light-emitting element 26 to be assembled at an upper end of the heat-radiating housing 20 is simultaneously heat-exchanged with cold air in the vicinity of the heat-radiating housing 20 through the heat-radiating fins 24 and the parallel slots 241 by means of heat conduction and a thermal convection method, thereby significantly improving heat-radiating efficiency of the heat-radiating housing 20. <P>COPYRIGHT: (C)2012,JPO&INPIT |
