Description

The LED lamp radiator
Technical field
The utility model relates to a kind of LED lamp radiator, particularly relates to a kind of column construction and is furnished with the LED lamp radiator of through hole.
Background technology
LED is a light emitting diode, is a kind of semiconductor solid luminescence device.It is to utilize the solid semiconductor chip as luminescent material, by carrier compound energy of emitting surplus takes place and cause photo emissions in semiconductor, directly sends each coloured light such as red, blue, green.The LED illuminating product utilizes LED as the produced ligthing paraphernalia of light source exactly.Under the background that the worry of current global energy shortage raises once again, energy savings is the important problem that we face, at lighting field, the application of LED luminous product is just attracting common people's sight, LED is as a kind of novel green light source product, must be the development trend of lighting engineering, 21st century will be to be the novel illumination light source epoch of representative with LED.LED be called as the 4th generation lighting source or green light source, have characteristics such as energy-saving and environmental protection, the life-span is long, volume is little, can be widely used in fields such as various indications, demonstration, decoration, backlight, general lighting and urban landscape.In recent years, some developed countries have launched fierce technology contest around the development of LED in the world.
The LED product has vast market prospect beyond any doubt, especially at lighting field, will be a revolution on the human illumination history if led light source is widely used in lighting field, but can't extensively promote at present by the restriction of factors such as technology.At first, no matter be the sealing problem what LED product all is faced with waterproof, protection against the tide, if handle the bad service life that will directly influence the LED product, and these safeguard procedures can cause LED lamp ambient temperature to rise; Secondly, after ambient temperature raise, led light source internal resistance meeting reduced, if use the voltage-stabilized power supply power supply can cause the LED operating current to raise, after surpassing its rated operational current, can influence the service life of LED product, and the serious led light source that will make " burns out ".So the LED lamp especially heat dissipation problem of high-powered LED lamp is the main bottleneck of its extensive use of restriction.
The importance that LED dispels the heat is that also the height of LED junction temperature directly influences the life-span of LED, general estimation, if the junction temperature of LED reduces by 10 °, the life-span can increase by 50%, and as seen thermolysis is huge.
For this reason, the manufacturing enterprise of each LED illuminating product is all in the version of seeking to have better radiating effect.What taked usually all is the device that utilizes heat conduction and heat radiation principle design LED heat radiation, as Chinese utility model patent ZL200520064989.9 integrated LED lamp radiating device and Chinese invention patent application 200510037514.5 integrated LED lamp radiating devices, last lower shell surface is designed to the radiator shape, the heat that the LED lamp produces is transmitted to housing, carries out heat exchange by housing and air again; And for example Chinese utility model patent ZL200520065298.0 high-capacity LED heat sink for lamp has been described the LED lamp socket and has been connected heat radiation rack, connects the structure of fin again by bolt, also is to have used heat conducting principle.Only set about changing radiator structure, can solve the heat dissipation problem of low power LED lamp to a certain extent, just can not be delivered in the air at short notice at the heat that high-powered LED lamp produced from the heat conduction.Therefore, need fundamentally solve heat dissipation problem.
The utility model content
Technical problem to be solved in the utility model provides a kind of LED lamp radiator, the LED lamp radiator that particularly provides a kind of column construction that through hole is arranged.The utility model is the technology of having utilized cross-ventilation, heat conduction and heat radiation to combine, remedied deficiency and defective that prior art can't solve the heat dissipation problem of great power LED, meets the demands of production and living.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of LED lamp radiator, be used for the heat radiation of light emitting diode, radiator is a column construction, the cylindricality top is the mounting platform of LED, have some through holes along the radiator axis direction around the LED installation region on the mounting platform, on mounting platform, also have LED lead-in wire routing hole.
As optimized technical scheme:
Described column construction is cylinder-shaped.
Described column construction has a connecting rod of being convenient to fixed heat sink in the middle of the reverse side of the mounting platform of LED.
Described connecting rod adopts solid or hollow-core construction, and can there be screw thread the connecting rod end, is convenient to be installed to lamp socket.
Described column construction has some radiating fins, or the heat radiation window, or the combination of radiating fin and heat radiation window.
Described column construction comprises that column construction comprises cylindrical, truncated cone-shaped, prismatic, terrace with edge shape, dolioform and other column geometrical body.
Some LED installation region is arranged on the mounting platform of described radiator, one or several LED can be installed and realize that circuit connects.
Described radiator is by aluminium, aluminium alloy, copper or copper alloy manufacturing.
Described through hole is arranged near the LED installation region.
As everyone knows, cross-ventilation is inequality because air is heated, and the air that is heated expands and rises, and the air of catching a cold sinks, and convection current is the best mode that air heat is transmitted.The utility model utilizes this principle just, particularly when the LED light fixture adopts protector, will form a confined space around the light source, the heat that is produced will make the environment temperature of LED light fixture sharply rise, because the utility model is provided with through hole and heat radiation window around LED, make the hot-air of this confined space and lamp cold air behind produce convection current, therefore most heat can scatter and disappear with air rapidly, through hole is the closer to LED, and convection effects is obvious more; Moreover the utility model has adopted the good material of heat-conducting effect, and closely is connected with LED, and remaining heat can be by heat conduction and the very fast dissipation of thermal-radiating mode.So, make the operating ambient temperature of LED remain at zone of reasonableness.In actual life, many devices are all carried out forced convertion with fan, can receive great heat radiation effect.But can increase cost and complexity greatly with fan in the light fixture.The utility model is to utilize free convection but not forced convertion.
The beneficial effects of the utility model are:
LED lamp radiator radiating rate of the present utility model is fast, and the technology of having utilized cross-ventilation, heat conduction and heat radiation to combine has solved the heat dissipation problem of great power LED; Simple and reasonable, utilized Natural Heat Convection efficient height; Easily manufactured, cost is low, good heat dissipation effect.
