Fig. 1 is the stereogram of the LED light fixture of an embodiment;
Fig. 2 is the structural representation of LED light fixture shown in Figure 1;
Fig. 3 is the profile along the III-III line in Fig. 1;
Fig. 4 is the top view of LED light fixture shown in Figure 1.
[specific embodiment]
Below by the specific embodiment, above-mentioned LED light fixture is further set forth.
See also Fig. 1, Fig. 2 and Fig. 4, the LED light fixture 100 of an embodiment comprises lamp housing 10, LED20 and installation portion 30.
See also Fig. 3, be filled with cooling fluid 40 in cavity.The heat that produces when cooling fluid 40 can be luminous with LED 20 carries out heat exchange, gives LED 20 processings of lowering the temperature, thereby extends the service life of LED 20 and the effective light decay of reduction LED 20.Cooling fluid 40 can be selected from least a in water, ethylene glycol, glycerine.Because the mixture of water and glycerine has advantages of that boiling point is high, volatility is little, is difficult for catching fire, nontoxic, corrosivity is little, in preferred scheme, adopts the mixture of water and glycerine, namely glycerine is as cooling fluid.The top of upper lamp housing 11 offers coolant injection hole 114, and coolant injection hole 114 is used for adding inject cooling liquid 40 to cavity.Add fill with after, 114 use hexagon socket head cap screws 115 sealings of coolant injection hole.Be enhanced leaktightness, in present embodiment, seal again coolant injection hole 114 after putting O shape sealing Figure 116 on hexagon socket head cap screw 115.When needs add inject cooling liquid 40, adopt inner hexagon spanner to turn on hexagon socket head cap screw 115 and get final product.
The outer wall of lower lamp housing 12 is provided with a plurality of fin 122.Fin 122 is trapezium structure, and its stub end matches with the inverted round table shape structure with lower lamp housing 12 near upper lamp housing 11, strengthens aesthetic feeling.Be appreciated that fin 122 can be other shapes.Fin 122 uniformly-spaced is arranged on the outer wall of lower lamp housing 12.The quantity of fin 122 can be according to the power selection of LED light fixture 100.Fin 122 the contact area that has increased time lamp housing 12 and outside air is set, strengthened cooling to lower lamp housing 12 outer surfaces of atmospheric temperature, thereby strengthened the radiating effect of LED light fixture 100.
When LED light fixture 100 was lighted, the heat that LED 20 produces passed to cooling fluid 40 by upper lamp housing 11.Because the temperature of cooling fluid 40 itself is lower, the heat that LED 20 produces can pass to rapidly cooling fluid 40, and cooling fluid 40 transfers heat to lower lamp housing 12 again, and final heat distributes by fin 122.
Heat radiation is mainly by transmitting and distributing dual mode and carry out, LED light fixture 100 inside are filled with cooling fluid 40, and the outer wall of lower lamp housing 12 is provided with fin 122, the thermolysis of heat transfer process and fin 122 by cooling fluid 40, can efficiently the dissipation of heat of LED light fixture 100 be gone out, thereby reach the purpose of lowering the temperature to LED light fixture 100.
In preferred scheme, also be provided with equally spacedly heat radiation boss 112 on the outer wall of upper lamp housing 11, LED20 is arranged on heat radiation boss 112.Heat radiation boss 112 is isosceles trapezoidal structure, adjacent two heat radiation boss, 112 these formation heat dissipation channels 117.The area of dissipation that the arranging of boss 112 of dispelling the heat forms heat dissipation channel 117 and increased upper lamp housing 11, the part heat that makes LED 20 produce also can distribute from upper lamp housing 11, and the heat dispersion of LED light fixture 100 is provided on the whole.
In preferred scheme, lamp housing 10 is made by metal material.The heat conductivility of metal material is better, is conducive to the heat radiation of LED light fixture 100.Particularly, lamp housing 10 can be made by silver, copper, aluminium, the steel of perfect heat-dissipating, perhaps adopts aluminium alloy to make.The heat conductivility of comprehensive metal material and price consideration, present embodiment adopts aluminium alloy to make lamp housing 10.The lamp housing 10 that aluminium alloy is made has advantages of that also weight is little simultaneously.
Further, LED light fixture 100 also comprises the electronic devices and components (not shown), and electronic devices and components are arranged at lamp housing 10 inside and are electrically connected to LED 20.The inside of lower lamp housing 12 is provided with barrier sheet 15, and the bottom of barrier sheet 15 and lower lamp housing 12 surrounds annular seal space 16, and electronic devices and components are arranged at described annular seal space 16 inside.Barrier sheet 15 is set to avoid electronic devices and components to be subject to the corrosion of cooling fluid 40.
Be appreciated that electronic devices and components can omit, LED 20 is connected with outside electronic devices and components gets final product.
Be filled with cooling fluid 40 in the sealed cavity of the lamp housing 10 of LED light fixture 100, and be provided with a plurality of fin 122 on the outer wall of its lower lamp housing 12, the thermolysis of heat transfer process and fin 122 by cooling fluid 40, can efficiently the dissipation of heat of LED light fixture 100 be gone out, thereby reach the purpose to 100 coolings of LED light fixture, thereby the service life that can effectively improve LED light fixture 100.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.Should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
