The technical problem that the utility model will solve provides a kind of LED light fixture; Its adopt thermal diffusivity preferably ceramic material as heat-dissipating casing; And pass through area of dissipation and the performance of ventilating that architecture advances improves the ceramic heat-dissipating shell, and beautify lamp body structure simultaneously, improve the outward appearance of LED light fixture.

The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals: a kind of LED light fixture comprises standard lamp socket, lamp body, lampshade and LED lamp group; Said LED lamp group is arranged in the said lamp body; Said LED lamp group comprises aluminium base, is arranged on some LED lamps and driving power on the aluminium base, and said lampshade is arranged on said lamp body front end and covers said LED lamp; Said lamp body comprises the inner barrel that is connected with said standard lamp socket and is arranged on the heat dissipating housing on the said inner barrel periphery; Said heat dissipating housing comprises that the radiating fin that is the radiation setting is located at the outer case of said radiating fin with the interval, is provided with some air vents on said case.Through the case of band air vent is set outside radiating fin; Make to form a gas channel between it, quicken the heat radiation of radiating fin, thereby effectively solve the heat dissipation problem of LED light fixture through air current flow; Improved the reliability of LED lamp; Simultaneously, case the appearance and modeling space that has increased the LED light fixture is set, make the LED light fixture have better outward appearance.

As a kind of optimized technical scheme: said inner barrel is provided with at the bottom of the tube, and said aluminium base is fixed on outside, the said tube end, and said driving power is arranged in the said inner barrel.Through directly contacting, improved the outside transfer rate of heat of LED lamp with at the bottom of the tube.

As a kind of optimized technical scheme: said case outer surface is the moulding of lotus flower seat, and it is protruding to be provided with some equally distributed lotus flower flaps; The port of said case is shunk and is linked to each other with said inner barrel upper end screw socket.Further, said air vent is arranged on the protruding top of each lotus flower flap.Said lotus flower flap is protruding divides two-layer up and down dislocation ringwise to arrange; Said radiating fin comprise be height straggly and with said lotus flower flap protruding corresponding lengthy motion picture and short-movie.This structure is looked after the appearance and modeling of LED light fixture on the one hand, simultaneously, utilizes the heat dissipation channel of the ingenious formation radiating fin of this architectural feature.

The utility model is provided with case according to convective principles outside radiating fin, make a heat dissipation channel of formation, through flowing of thermal current, has accelerated the heat radiation of LED light fixture.And; The utility model has utilized the modeling structure of case dexterously; The heat dispersion and the outward appearance of LED light fixture are combined ripping, make not only that the transmission of LED light fixture heat is faster, radiating effect is better, reliability is higher, but also make the LED light fixture have outward appearance plasticity more flexibly.
