The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation of a kind of high-power LED lamp with heat pipe of the present invention.
Among the figure: 2, lamp housing, 4, the LED luminescence component, 6, lampshade, 8, radiating fin, 10, radiator, 12, heat-radiating substrate, 14, led chip, 16, heat pipe, 18, evaporator section, 20, condensation segment.
The specific embodiment
In order to make those skilled in the art person understand the present invention program better, and above-mentioned purpose of the present invention, feature and advantage can be become apparent more, the present invention is further detailed explanation below in conjunction with embodiment and embodiment accompanying drawing.
As shown in Figure 1, a kind of high-power LED lamp with heat pipe, described LED light fixture comprises that the inside of round platform taper both ends open is equipped with the lamp housing 2 of LED luminescence component 4, the upper end open place of lamp housing 2 is provided with the radiator of being made up of a plurality of radiating fins 8 10, radiating fin 8 can be made good heat dissipation effect by aluminium matter or the high material of thermal conductivity factor such as copper; The lower ending opening place of lamp housing 2 is provided with lampshade 6, wherein, lampshade 6 can be formed by materials in tension and compression such as two-way mirror, prism glass, polished aluminums, can obtain wide light distributes, be suitable for large tracts of land, working face is vertical or subvertical workplace, throw light on as wall face panoramas such as ore deposit factory hoistway, large-scale medical, chemical industry factory building, viaduct, landmarks.
Special feature of the present invention is that LED luminescence component 4 comprises the heat-radiating substrate 12 and the led chip 14 that is attached on the heat-radiating substrate 12 of aluminium matter, heat pipe 16 is also fixedly arranged on the heat-radiating substrate 12, heat pipe 16 is that a kind of phase transition process that utilizes absorbs/product of distribute heat, mainly formed by shell and capillary wick, negative pressure state will be pumped in the pipe, charge into lower boiling liquid, temperature when considering the work of LED light fixture, can select to fill highly purified water, acetone, liquefied chlorine one or both combination wherein, after the filling, make to be sealed after being full of liquid in the capillary wick pore be close to inside pipe wall.One end of heat pipe 16 is evaporator section 18, evaporator section 18 is fixed on the heat-radiating substrate 12, the other end is condensation segment 20, condensation segment 20 stretches out heat-radiating substrate 12 and is connected with radiator 10, form the loop of medium work between evaporator section 18 and the condensation segment 20 mutually, during light fixture work, led chip 14 produces heat is given heat pipe 16 by heat-radiating substrate 14 conduction evaporator section 18, when evaporator section 18 is heated, low-boiling point liquid in the pipe can be because of the evaporation rapidly of being heated, steam flows to the condensation segment 20 of the other end rapidly under small pressure reduction, after discharging heat, the steam regelation becomes liquid, and liquid flows back to evaporator section again by capillary attraction and self gravitation effect, so circulation is more than, constantly transmits heat.Heat pipe has high heat transfer, heat conductivility, inner liquid can be recycling, can guarantee the high reliability of LED light fixture long-term work, under the prerequisite that does not increase light fixture weight, improve the heat-sinking capability of light fixture greatly, be beneficial to the later stage installation, the regional panorama illumination that is particularly suitable for high wind, adverse circumstances is used.
For the quick backflow of steam after condensation segment 20 condenses into liquid, during design the position of evaporator section 18 is lower than the position of condensation segment 20, avoid falling the backflow of prevention liquid because of the pressure that liquid produces because of self gravitation.
Preferably, in order further to improve radiating effect, heat pipe 16 adopts the copper heat pipe, and copper is big than the thermal conductivity factor of aluminium, and is low than silver-colored cost.
Above-described embodiment is preferred implementation of the present invention; but embodiments of the present invention are not limited by the examples; other any do not deviate from change, the modification done under spiritual essence of the present invention and the principle, substitutes, combination, simplify the substitute mode that all should be equivalence, is included within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claim was defined.
