The contact area of ambient enviroment, to considerably improve the heat dissipation effect of radiator.Certainly, the second cooling fin can also have
There is the cross section profile of the contact area that can increase the first cooling fin and ambient enviroment of other types.
Advantageously, the first Heat Conduction Material is the heat-conducting plastic of electrical isolation.Heat-conducting plastic have it is light-weight, it is at low cost, easily
In configuration and processing and manufacturing the advantages of.Certainly, the overall of radiator is further reduced using the heat-conducting plastic of insulation to occupy
Space, this is because the heat-conducting plastic of insulation good can insulate to electronic equipments such as drivers, without driving
It is dynamic that larger creepage distance is set between device and radiator.
Advantageously, the second Heat Conduction Material is copper-based or aluminium based metal material.Second Heat Conduction Material of metal has good
Heat conductivility, which raises the heat dissipation performances of radiator.
Preferred design scheme according to the present invention proposes that the second radiator structure is wrapped in by inlaying injection molding process
In first radiator structure.The second radiator structure and the first radiator structure is set closely to be incorporated in one by inlaying injection molding process
It rises, so as to avoid occurring increasing the air gap of thermal resistance between two radiator structures, this is conducive to the heat dissipation for improving radiator
Performance, while also simplifying the manufacture difficulty of radiator.
Preferably, the second supporting part not by the first supporting part wrap up part be designed as the heat source for lighting device
Contact surface.The heat source of lighting device and the direct thermal conductive contact of the second supporting part, This further reduces the heat on thermally conductive pathways
Resistance.
Advantageously, in order to improve cross-ventilation effect, the first cooling fin is protruded in the side of the first supporting part, and that
This is spaced apart with scheduled spacing.
Another object of the present invention is achieved in by lighting device, which includes dissipating for light source and the above-mentioned type
Thermal, wherein the second supporting part thermal conductive contact of light source and radiator.One according to the present invention preferred design side
Case, light source design is at LED luminescence components.
