Background technology
LED as forth generation new green environment protection light source, have that light efficiency is high, life-span length, energy-conserving and environment-protective, the advantage such as safe and reliable, but temperature rise is the lethal factor affecting LED.
The electric energy conversion of 30-40% is only had to be luminous energy during LED work, the electric energy conversion heat energy of all the other 60-70%, in addition the heat produced during driving power work, LED is caused to produce temperature rise, and temperature rise can affect life-span of LED, light efficiency, photochromic, colour temperature, luminous intensity distribution light shape and forward voltage, peak point current, brightness, colourity, electric parameter, reliability etc., temperature rise simultaneously can affect the performance of LED drive power.In some large regions illumination utilization field, along with LED power increases, temperature rise is larger.Therefore heat dissipation problem is very important.
Existing market LED operationally, the heat that LED produces reaches radiator through substrate, gone out by heat sink radiates again, owing to being subject to lamp interior space constraint, the area of dissipation of heat abstractor is limited, the high thermal conductance produced when can not effectively be worked by LED goes out outside, causes heat to hoard at interiors of products, affects the performance of LED.
Utility model content
The utility model overcomes the deficiency that prior art exists, and provides a kind of rational in infrastructure, diversified Novel LED light radiator of radiating mode.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of LED lamp heat sink, comprise circular radiator open tubular column and fin, described fin is evenly arranged on outside radiator open tubular column, and radiator open tubular column and fin one-body molded, the inner side of described radiator open tubular column is provided with multiple groove, multiple described groove is vertically arranged on radiator open tubular column, described fin is large mouth upward tubaeform, the top of described fin is higher than the top of radiator open tubular column, described fin has multiple radiating fin at the inside circumference array higher than radiator open tubular column top.
The bottom of described radiator open tubular column is provided with battery base, and the bottom Corresponding matching of described battery base and radiator open tubular column is arranged, and the card base correspondence that battery base is arranged snaps in groove.
Described radiator open tubular column is provided with heat radiation aluminum component, and the upper end of described heat radiation aluminum component is provided with lamp plate, the edge of described lamp plate and the tip edge of fin in the same size, and described fin with heat radiation aluminum component and lamp plate between be connected with screw.
Described fin is arranged in the outside of radiator open tubular column in the form of a ring with array way.
The upper end of described fin is provided with lampshade.
The beneficial effect that the utility model compared with prior art has is: the utility model fin is fixed on around radiator open tubular column circlewise, and the thickness between fin, spacing and outer peripheral form are all to change according to demand.Fin and radiator open tubular column are formed in one, and reduce work hours, operation and some processing charges, and good heat dissipation effect.Be provided with battery base below radiator open tubular column, have three grooves for locating in radiator open tubular column, internal edge is consistent with base edge, facilitates assembling and the location of light fixture.The inner height of fin section differs, and this form is combined with outer gap structure, carries out good hot fluid circulation, is taken away by the heat of lamp plate and power supply generation, when fin quantity and material constant, add cross-ventilation, improve radiating effect.The structure of fin inside is one of key of described design, and being converted to by the inner-cavity structure of traditional closed can the structure of heat loss through convection.Thus radiator is converted into heat transfer, thermal convection current combination heat radiation.The fin quantity of the utility model radiator, fin internal height difference are dispelled the heat needed for different capacity LED lamp panel, driving power and determine.The heat radiation bottom of aluminum component and radiator open tubular column are combined closely, and top and lamp plate are combined closely, thus transferring heat better.
