Fig. 2 is the axial section of the light fixture that provides of the preferred embodiment for the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawing in embodiment of the present invention, the technical scheme in embodiment of the present invention is clearly and completely described.
See also Fig. 1 to Fig. 2, a kind of light fixture that embodiment of the present invention provides, comprises light source assembly 4 and lamp heat-radiating device.Lamp heat-radiating device comprises heat-dissipating cylinder 1, isolating cylinder 2 and fan 3.Heat-dissipating cylinder 1 comprises cylindrical shell 11, top cover 12 and base plate 13, and top cover 12 and base plate 13 are separately positioned on cylindrical shell 11 two ends and make the space of the interior formation sealing of heat-dissipating cylinder 1, to ensure the degree of protection (IP) of light fixture.Light source assembly 4 is LED light source, is fixed on the outer wall of base plate 13.Cylindrical shell 11 and base plate 13 are made by heat-conducting, are beneficial to heat radiation.
There is gap respectively and between top cover 12 and base plate 13 in the two ends of isolating cylinder 2, between the outer wall of isolating cylinder 2 and the inwall of cylindrical shell 11, has gap, makes that isolating cylinder 2 is unsettled to be arranged in heat-dissipating cylinder 1.The outer wall of isolating cylinder 2 is by connecting rod or be parallel to the modes such as the axial connecting plate of isolating cylinder 2 and be fixedly connected with cylindrical shell 11, and makes to have the gap of being convenient to Air Flow between isolating cylinder 2 and heat-dissipating cylinder 1.Certainly, can be also that base plate 13 is fixed on base plate 13 by the end of isolating cylinder 2 by modes such as connecting rods after being fixedly connected with cylindrical shell 11.
Fan 3 is fixed in isolating cylinder 2, cylindrical shell 11, isolating cylinder 2 and fan 3 threes' axially parallel, as preferably, three coaxially arranges, make the circular gap between isolating cylinder 2 and heat-dissipating cylinder 1 even, make the inner air of heat-dissipating cylinder 1 flow evenly and cylindrical shell 11 is heated evenly simultaneously.
As preferably, the air-out direction of fan 3, towards base plate 13, blows away with the heat as early as possible light source assembly 4 being produced.Fan 3 is arranged on the end of isolating cylinder 2, and preferably, fan 3 is arranged on the end of isolating cylinder 2 near base plate 13, to blow to base plate 13 with maximum wind-force, as early as possible the air that absorbs heat is blowed to cylindrical shell 11 inwalls; Meanwhile, what extract due to fan 3 is to carry the inner air of less heat after heat radiation, can avoid the damage of heat to fan 3.Certainly, fan 3 also can be arranged on the middle part of isolating cylinder 2 or isolating cylinder 2 end or other positions near top cover 12.
Preferably, top cover 12 is made up of heat-conducting, further to strengthen the heat dispersion of heat-dissipating cylinder 1.
Preferably, the inwall of heat-dissipating cylinder 1 is provided with radiating groove or radiating ribs.The inwall of base plate 13 is provided with radiating groove or radiating ribs, and the heat that can be convenient to base plate 13 is to the oxygen diffusion in heat-dissipating cylinder 1.The inwall of cylindrical shell 11 and top cover 12 is provided with radiating groove or radiating ribs, can be convenient to cylindrical shell 11 and top cover 12 and absorb the heat of heat-dissipating cylinder 1 inner air.
For reinforced tube 11 is to outside dissipate heat, the outer wall of heat-dissipating cylinder 1 is provided with radiating groove or radiating ribs, and the outer wall of cylindrical shell 11 and/or top cover 12 is provided with radiating groove or radiating ribs.
After light source assembly 4 is lighted, LED light source send heat energy absorbed by base plate 13, and be transmitted on the medial surface of base plate 13, fan 3 is dried to base plate 13, mobile air is stopped that by base plate 13 rear gap between heat-dissipating cylinder 1 and isolating cylinder 2 is mobile to top cover 12, and airborne heat can be absorbed by the barrel of heat-dissipating cylinder 1 and be delivered in the air of outside simultaneously; This process reduces the entrained heat of inner air.Inner air continues to flow to top cover 12, hoards after running into top cover 12, and is taken away by fan 3, thereby form a circulation in the interior outside of isolating cylinder 2, utilizes inner air circulation to accelerate the conduction of heat, reaches the object that improves radiating efficiency.As preferably, the axial length of isolating cylinder 2 is greater than the axial length of fan 3, can be in heat-dissipating cylinder 1, the interior outside of isolating cylinder 2 forms an orderly circulation, is beneficial to heat radiation.In this circulation, the flow direction of heat energy is followed successively by: LED light source, base plate 13, inner air, cylindrical shell 11 and top cover 12, outside.
The above is the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications are also considered as protection scope of the present invention.
