The specific embodiment
See also Fig. 1 to Fig. 3, the led lamp of one embodiment of the invention comprises a lamp socket 10, a radiator 20, some light-emitting diodes 30 and a lampshade 40.
Above-mentioned lamp socket 10 is used for being electrically connected to fetch with external power source being the led lamp power supply.
Above-mentioned radiator 20 is installed on the described lamp socket 10, and it adopts high heat conduction and electrically insulating material to be made into integration, as ceramic material.Preferably, described ceramic material is selected from any in aluminium oxide, silicate, oxide, carbide, nitride, sulfide, the boride.The cylindrical shell 24 of the lengthwise that this radiator 20 comprises a substrate 22, protrude out downwards from substrate 22 bottom surfaces and the some radiating fins 26 that stretch out from cylindrical shell 24 outer peripheral edges.The end face middle part of described substrate 22 further protrudes out vertically upward and forms a cylindric installation portion 220, is sticked thereon for described light-emitting diode 30.Being formed with circuit on the described installation portion 220 is electrically connected with light-emitting diode 30.Preferably, this circuit is formed on the end face of described installation portion 220 by electric plating method.In the present embodiment, by on the end face of the installation portion 220 of the substrate 22 of radiator 20, directly forming circuit and light-emitting diode 30 be installed, can reduce the thermal resistance between light-emitting diode 30 and the radiator 20 greatly, effectively improve the radiating efficiency and the radiation stability of led lamp.Described radiating fin 26 is radial even, setting at interval around described cylindrical shell 24, and all links to each other with the bottom surface of substrate 22.Described cylindrical shell 24 is fixedlyed connected with described lamp socket 10 away from an end of substrate 22.Described led lamp comprises that also a driving module 100 is contained in the described cylindrical shell 24, thereby reduces the volume of whole led lamp.This drives module 100 and is electrically connected with lamp socket 10 and light-emitting diode 30, is used to light-emitting diode 30 that driving voltage is provided.Be appreciated that ground, the fixed form of described cylindrical shell 24 and lamp socket 10, and drive the position is set should be not limited to present embodiment of module 100.Also be formed with at least one through hole that runs through described substrate 22 221 on the installation portion 220 of described substrate 22, be electrically connected with light-emitting diode 30 for described driving module 100.Be recessed to form a mounting groove 222 downwards around described installation portion 220 on the end face of described substrate 22, this mounting groove 222 is used for cooperating the described lampshade 40 of installation.
Please consult Fig. 4 simultaneously, described substrate 22 is formed with at least one louvre 224 near peripheral region.Described louvre 224 vertically connects this substrate 22, promptly connects the end face and the bottom surface of this substrate.In the present embodiment, the quantity of described louvre 224 is a plurality of, and these louvres 224 are circular even a, setting at interval along the outer peripheral edges of substrate 22.Be appreciated that ground, when the quantity of described louvre 224 is a plurality of, can further be interconnected by the mode of offering through hole in substrate 22 inside between adjacent two louvres 224.Each louvre 224 places between adjacent two radiating fins 26 in the opening part correspondence of substrate 22 bottom surfaces.And, of the periphery setting of described louvre 224 in the opening part of substrate 22 bottom surfaces around described cylindrical shell 24.The size of each louvre 224 reduces to the direction of bottom surface gradually along the end face of substrate 22, makes described louvre 224 be the pyramidal structure of reducing in the direction.
