Described one chip LED lamp housing is connected by radiator and light fixture fixation kit and forms, radiator comprises a radiator outer rim and at least one heat transfer substrate, heat transfer substrate is simultaneously established smooth mounting plane, another side is established fin, the heat transfer substrate periphery is established interlaced fin between the fin outer rim, organizes fin more and intersects to form opening.

Described fin can be plane or curved surface, and its thickness is the 1-5 millimeter, highly is 1-20 centimetre; The general aluminium alloy of its material, albronze or titanium magnadure.

Described heat transfer substrate thickness is set between 0.5-2 centimetre, establishes the screw hole that led light source and light-distribution lens are installed on it.

Described led light source is made by the integrated encapsulation of high-power LED chip, led chip is by lead series connection or compose in parallel matrix and arrange and place and form the led light source module in the module carrier, and be provided with two faces, a light-emitting area and a thermal conductive surface, thermal conductive surface is made by the little metal of thermal resistance, should comprise the screw hole that is connected with lamp radiator on it, thermal conductive surface is connected in heat transfer aluminium base lower surface by screw and heat-conducting glue.

Described light-distribution lens is fixed on heat transfer aluminium base lower end mounting plane by glass or resinous material compression molding by the lens retainer ring; The lens retainer ring is the metal ring structure, and middle perforate and light-distribution lens coupling are fixed in the heat transfer aluminium base by screw.

Described driving power is AC/DC or DC/DC constant current source of stable pressure, output voltage and power and led light source coupling.

Good effect of the present utility model: one chip LED lamp housing different with the particularly traditional road illuminating lamp of conventional lamp on the structure of lower casing, the creationary one-piece construction of taking makes fitting structure simpler, reduces raw-material consumption, saves production cost; Through hole grid radiator forms a plurality of flow channels, the air themperature of radiator periphery can increase when light fixture point brightness temperature raises, frivolous hot-air can rise, hot-air after the rising will form negative pressure at the radiator periphery makes colder air fill up, so just formed the exchange of heat, the formation cross-ventilation that so goes round and begins again improves radiating efficiency.
