Because the restriction of semiconductor light-emitting-diode wafer technologies at present, the photoelectric transformation efficiency of LED are still waiting to improve, especially great power LED; Because of its power higher; Nearly electric energy more than 60% will become heat energy and discharge (along with development of semiconductor, photoelectric transformation efficiency can improve gradually), and this just requires terminal client in utilizing high power LED product; Carry out heat radiation work, to guarantee great power LED product operate as normal.The heat increase that high-powered LED lamp is produced in unit volume is very fast, and therefore the LED components and parts being carried out thermal control is its major issue that advances.Meanwhile; Effectively area of dissipation but reduces relatively, because the reliability and the temperature of LED element are inversely proportional to, rate of breakdown raises and the exponent function relation growth with LED components and parts temperature; Therefore should strictly control LED components and parts temperature, thereby solve the LED light decay problem that causes because of the deficiency of dispelling the heat; Therefore heat dissipation technology has become the emphasis problem of studying reliably.And the existing general radiating mode that adopts is: Natural Heat Convection, high wind cooling, heat pipe heat radiation, and other radiating mode, and compare from cost and application facet: the Natural Heat Convection cost is minimum, uses the widest; High wind cooling moderate in price, range of application is wideless; The heat pipe heat radiation cost is too high, and technology is perfect inadequately, and range of application is narrow.
It is particularly important for the heat radiation of LED in high-power LED is used; Adopt the Natural Heat Convection method of traditional structure can't solve this difficult problem at all; And traditional great power LED product adopts the mode of welding that the performance of LED is had very big influence in manufacture process; LED is caused very big impact, more fail to utilize the method for this Natural Heat Convection to be implemented on the high-power LED light source of miniaturization; Have only the heat abstractor of making new structure, its radiating effect is strengthened greatly, also will change traditional heat dissipating method LED heat radiation reliability several times are improved.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, provide a kind of simple in structure, save installing space, the easy for installation and significant radiator of radiating effect.
The technical scheme that the utility model solves existing LED heat spreader structures is: a kind of upright post type LED heat radiator; Comprise a upright post type radiator cylinder; Wherein aforesaid cylinder is an integral structure; Cylinder is provided with conducting cylinder two ends and forms the groove assembly of annular array, and a concave end of cylinder has places the groove that LED lamp pearl is installed; Also be provided with the passage of the conducting groove and the cylinder other end on the cylinder.The structure that this radiator is integrated, manufacturing procedure is simple, reduces consumptive material, has reduced production cost, can avoid the situation of the radiator laying dust of traditional fin form; In addition, the special construction that this radiator utilizes groove always to be shaped as has the dual radiating effect of heat loss through radiation and heat loss through convection, can make the heat conduction accelerate, and strengthens radiating effect, forms " chimney " effect when making radiator heat-dissipation.Simultaneously, the groove that is provided with in this radiator can directly be installed LED lamp pearl, and the copper guide pillar of LED lamp pearl directly contacts with the bottom surface of groove, can strengthen radiating effect and accelerate the heat conduction; This mounting means can be saved aluminium base again, further reduces production costs.
As the further design to the aforementioned techniques scheme: the groove assembly that forms annular array is provided with two-layer, and ground floor groove assembly is arranged near the cylinder outside, and second layer groove assembly is arranged at the position near groove.There is fansink designs two-layer groove assembly can form dual heat loss through convection, accelerates the inside and outside heat radiation of upright post type radiator, impel the quick heat radiating of LED lamp pearl simultaneously.
As the further design to the aforementioned techniques scheme: aforementioned recess is provided with one, and second layer groove assembly is around surrounding groove; Described second layer groove assembly includes three arc-shaped slots, and each groove area of second layer groove assembly is all greater than each groove area of ground floor groove assembly.Second layer groove assembly is primarily aimed at LED lamp pearl and carries out quick heat radiating, and its groove area is bigger, and the convection current flow of formation is more naturally, and so just the timely quick heat radiating of ability in time reduces the temperature of LED lamp pearl.
Through practice experiment proof; The radiator of the utility model to the best design of aforementioned techniques scheme is: second layer groove assembly includes three arc-shaped slots, and each groove area of second layer groove assembly is all greater than each groove area of ground floor groove assembly; Described groove is provided with three, and each groove all is arranged between each arc-shaped slot of second layer groove assembly.
In sum, the LED radiating appliance of the utility model has following advantage:
⑴ integral structure: operation is simple during production and processing, has reduced consumptive material and has reduced production cost, can avoid the radiator laying dust again simultaneously;
⑵ easy for installation: the groove that is provided with in this radiator can directly be installed LED lamp pearl; The copper guide pillar of LED lamp pearl directly contacts with the bottom surface of groove; Saved aluminium base, can strengthen radiating effect and accelerate heat conduction, the damage of lens when avoiding rotational fixation LED lamp pearl simultaneously in groove;
⑶ dual heat radiation: the special construction that radiator utilizes groove always to be shaped as has the dual radiating effect of heat loss through radiation and heat loss through convection, can make the heat conduction accelerate, and strengthens radiating effect, forms " chimney " effect when making radiator heat-dissipation.
