Claim:
1. An LED photo-electric source assembly, comprising: a radiator, a radiating fan that is dust-proof and water-proof, a driving circuit board subassembly, an LED light source component, a power supply box having an upper cover with a port, and a lower cover sealed with the upper cover, thereby defining a sealed space therebetween; an annular insulator board, disposed in the sealed space between the upper cover and the lower cover, and surrounding the driving circuit board subassembly; and a waterproof bolt component, wherein the LED light source component comprises one or more LED chips and a LED submount; the radiator comprises a bottom plate whose underside is flat, on top of which a radiating part having a plurality of fins spaced a distance apart from one another in a circular or cylindrical arrangement is provided, in which the radiating part includes a space disposed substantially in the center of the radiating part for containing the radiating fan, and at least two shores extend outwardly from the radiator part beyond a top surface of the plurality of fins to support the lower cover; the LED submount is connected to the bottom plate that transmits heat; a thermal insulation synthetic mica sheet is provided between the LED submount and the bottom plate, wherein an edge of the thermal insulation mica sheet extends outward from an edge of the LED submount; the LED submount and the bottom plate are fixed through one or more first bolts, an insulating component envelops an end of the one or more first bolts and provides electrical isolation between the LED submount and both the bottom plate and the one or more first bolts; the radiating fan further comprises an air intake and an air outlet having top and bottom surfaces positioned in planes substantially parallel to one another, wherein a first fan guard is provided in the air intake and a second fan guard is provided in the air outlet; wherein on top of the radiating fan the lower cover is connected to the radiator; wherein the driving circuit board subassembly is disposed in the sealed space between the upper cover and the lower cover; and the waterproof bolt component connects to the port on the upper cover, wherein a power wire passes through the port of the upper cover.
