Detailed description of the invention
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.A lot of details are set forth in the following description so that fully understand the present invention.But the present invention can implement to be much different from alternate manner described here, and those skilled in the art can do similar improvement without prejudice to intension of the present invention in the situation that, and therefore the present invention is not subject to the restriction of following public specific embodiment.
Refer to Fig. 1 to Fig. 3, LED light fixture 10 comprises: radiator 100, reflection shield 200, lampshade 300, sealing ring 400, lamp socket 500, fixture 600 and LED lamp 700.Wherein, reflection shield 200, lampshade 300, sealing ring 400, lamp socket 500, fixture 600 and LED lamp 700 are all arranged in radiator 100, and lamp socket 500 parts are embedded on radiator 100.By reflection shield 200, lampshade 300, sealing ring 400, lamp socket 500, fixture 600 and LED lamp 700 are all arranged in radiator 100, radiating effect is better, can meet high-power LED light fixture and use.In addition, tradition is in traditional LED light fixture relatively, need to set up heat abstractor at shell, the radiator 100 of above-mentioned LED light fixture 10 can be directly used as shell and use, and there is fabulous heat conduction and radiating effect, manufacture difficulty is lower, and cost is lower, has reached integral structure, has been easy to produce and the effect of installing.
Refer to Fig. 4 and Fig. 5, radiator 100 comprises interior radiating component 110 and outer radiating component 120, the coated outer surface that is arranged on interior radiating component 110 of outer radiating component 120, the heat that interior radiating component 110 produces LED lamp is passed on outer radiating component 120, and be further delivered in extraneous air by outer radiating component 120, to strengthen radiating effect.For example, interior radiating component 110 and outer radiating component 120 are respectively individual components setting, and and for example, radiator 100 is integrated casting, to strengthen mechanical performance.And for example, as shown in the figure, the shape of radiator 100 is roughly horn-like structure, to strengthen the cooling surface area of radiator 100, also strengthens the gripping sense of radiator 100 simultaneously.And for example, radiator 100 is aluminium alloy heat radiator.For example, the specific area of outer radiating component 120 is 4 to 10 times of specific area of interior radiating component 110, and for example, the specific area of outer radiating component 120 is 6.8 times of specific area of interior radiating component 110.
Refer to Fig. 6, interior radiating component 110 comprises interior radiating component body 111, installing plate 112 and several heat radiation protuberances 113.Installing plate 112 is arranged in interior radiating component body 111, and several heat radiation protuberances 113 are arranged at interior radiating component body 111 outer surfaces.For example, interior radiating component body 111, installing plate 112 and several heat radiation protuberances 113 are respectively individual components setting, and and for example, interior radiating component 110 is integrated casting, to strengthen mechanical performance.
Refer to Fig. 7, the hollow structure that interior radiating component body 111 is both ends open, for example, interior radiating component body 111 is cylinder-like structure, and and for example, interior radiating component body 111 is aluminum alloy material, so that radiator 100 is realized light weight and lower-cost effect, and for example interior radiating component body 111 is copper material, to strengthen the heat-conductive characteristic of radiator 100, realizes the effect of flash heat transfer and heat radiation.And for example, the madial wall of interior radiating component body 111 arranges a heat-conducting layer (not shown), and for example, the thickness of described heat-conducting layer is 0.1mm～0.5mm, further to strengthen radiating effect.
Refer to Fig. 7, installing plate 112 is laterally fixedly installed on the madial wall of interior radiating component body 111, and makes interior radiating component body 111 interior separations form the first accommodating area 111a and the second accommodating area 111b.That is to say, the overall space of interior radiating component body 111 inside is separated to form the first accommodating area 111a and second accommodating area respectively with an opening by installing plate 112.Also can say, the both ends open of interior radiating component body 111 is respectively the opening of the first accommodating area 111a and the opening of the second accommodating area 111b.And for example, the opening bore of the first accommodating area 111a is greater than the opening bore of the second accommodating area 111b, and interior radiating component body 111 has by himself one end to the other end structure of convergent gradually, so that the structure of interior radiating component body 111 is compacter, improve industrial artistic design quality, increase and grip sense.
For the ease of the connection electrical wiring of the LED lamp of arranging is installed in actual production manufacture, for example, refer to Fig. 5 and Fig. 6, the spaced position place of the first accommodating area 111a and the second accommodating area 111b, be on installing plate 112, to offer several for wearing the through wires hole 112a of electrical wiring, like this, can be so that the connection electrical wiring of the LED lamp of arranging be installed in actual production manufacture.
Refer to Fig. 5 and Fig. 6, heat radiation protuberance 113 protrudes setting laterally by the lateral wall of interior radiating component body 111, and be provided with interval between several heat radiation protuberances 113, like this, can improve to a greater degree the integral heat sink specific area of interior radiating component 110, accelerate the heat that work produces to LED lamp and evacuate effect, thereby obtain outstanding radiating effect.For example, several heat radiation protuberances 113 radially distribute in the lateral wall of interior radiating component body 111, like this, between several heat radiation protuberances 113 and the lateral wall of interior radiating component body 111, can form several heat-dissipating spaces, thereby can improve the circulation of air effect of heat radiation radiation space and increase convection current air, reach rapid raising the heat of the shinny generation of LED lamp work is evacuated to effect, make shinny the produced heat Rapid radiating of LED lamp work in convection current air, so that LED chip is able to normal steady operation.For example, refer to Fig. 4, heat radiation protuberance 113 is extended to the opening part of the second accommodating area 111b by the opening part of the first accommodating area 111a, and forms gradually-reducing shape structure; For example it has trapezoid cross section, wedge shape section or triangular-section; And for example it is Rotary-table, cone or pyramid, like this, can further improve cooling surface area, reaches rapid raising the heat of the shinny generation of LED lamp work is evacuated to effect.
