[specific embodiment]

Below in conjunction with accompanying drawing the utility model is further described:

A kind of high-powered LED lamp is disclosed in the utility model, this light fixture adopts modularized design to constitute, especially adopted the module group that constitutes jointly by LED lamp module and heat spreader module to make a kind of modular high-power LED lamp, owing to adopted relatively independent module group to make up, so the LED light fixture of making has good performance of heat dissipation.Its primary structure is made up of lampshade 9, LED lamp 6, radiator 1, as shown in Figure 1, described LED lamp 6 and radiator 1 are relatively independent module and constitute, the utility model is a kind of a kind of great power LED lamp module group that adopts modularized design to form, its main feature is the basic function that has possessed the LED light fixture substantially, after simple combination, can be used to produce the LED light fixture of different capacity, adopt this module group to produce the LED light fixture, can reduce production costs significantly, simplify later period maintenance, reduce LED light fixture interim use cost in service life.As shown in Figure 2, wherein LED lamp module 3 is made up of at least two above LED lamps 6, and each LED lamp 6 all is arranged in the independent concave mirror 7, described two above concave mirror 7 common composition module plates, this module board back is provided with by LED circuit for lamp plate, each LED lamp 6 even these circuit board is electrically connected, gap between the described concave mirror 7 is provided with by louvre 8, the correspondence position of circuit board is provided with equally by louvre 8, LED lamp module 3 is made up of at least two above LED lamps, and each LED lamp 6 all is arranged in the independent concave mirror 7, described two
