At present, characteristics such as led light source is long, pollution-free with the life-span, light efficiency height are replace incandescent and fluorescent light just progressively, and single chip LED brightness is low, so led light source generally adopts led array formula structure, has produced the problem of LED lamp radiator heat-dissipation difficulty thus again.

Therefore, how designing a kind of quick heat radiating and rational in infrastructure, simple LED lamp radiator is the technical problem that needs to be resolved hurrily in the industry.

Summary of the invention

The main purpose of the utility model provides a kind of LED lamp radiator and a kind of LED lamp, on radiator, coats materials such as military project lacquer, is intended to realize that the heat radiation of light fixture is quicker.

The utility model proposes a kind of LED lamp radiator; Comprise that a heat radiation egative film reaches and the integrated some fin of said heat radiation egative film; Said fin is vertically set on the upper surface of said heat radiation egative film; Be provided with between the said fin at interval, on said fin and said heat radiation egative film, be coated with ceramic radiation heat radiation coating.

Preferably, the spacing distance between adjacent two said fin equates, is arranged in parallel between the said fin.

Preferably, on said heat radiation egative film, be provided with wire hole.

The utility model proposes a kind of LED lamp again; Establish the lamp body of led light source and the radiator that is connected with said lamp body in comprising; Said radiator comprises that a heat radiation egative film reaches and the integrated some fin of said heat radiation egative film, and the lower surface of said heat radiation egative film is connected with said lamp body bottom, and said fin is vertically set on the upper surface of said heat radiation egative film; Be provided with between the said fin at interval, on said fin and said heat radiation egative film, be coated with ceramic radiation heat radiation coating.

Preferably, on said heat radiation egative film, be provided with wire hole.

The utility model LED lamp radiator comprises that a lower surface can be connected the heat radiation egative film of heat conduction with led light source; The upper surface of heat radiation egative film is vertically installed with several cooling fins; The heat that produces when led light source is luminous can be directly passed to heat radiation egative film and fin, by heat radiation egative film and fin heat is distributed, and is coated with ceramic radiation heat radiation coating on heat radiation egative film and the fin; This ceramic radiation heat radiation coating is military project ash or military project lacquer; The heat radiation emissivity of this military project ash or military project lacquer can reach about 90%, can launch the heat energy of accumulating on heat radiation egative film and the fin with the mode of radiation, thereby accelerate radiating rate.The utility model LED lamp comprises above-mentioned radiator, can prevent that led light source is overheated, prolongs the service life of light fixture.
