Abstract
The invention relates to a large-power LED radiator which is formed in a way that three annular heat radiating pipes surround a central heat radiating base; rectangular heat radiating fins with a plurality of radial lengths are evenly distributed in a circumferential direction between the central heat radiating base and the outermost layer of heat radiating pipe. In the invention, by adopting the combination of a plurality of heat radiating units and carrying out the optimized option on the sizes of all parts, the large-power LED radiator is made of a pure aluminum material with high conductance on the basis of aerodynamic principles, therefore, the large-power LED radiator can be matched with a single or a plurality of large-power LED light sources, effectively and quickly dissipate heat generated by devices with very evident heat radiating effect; and meanwhile, the large-power LED radiator also solves the problem of overhigh junction temperature of LEDs and can remarkably prolong the service life of the LEDs, stabilize the quality of the LEDs and reduce emission decay of the LEDs, and the like.
Description
(1) technical field
The present invention relates to a kind of large-power LED radiator.
(2) background technology
In short supply and environmental pollution is day by day under the serious situation in global energy, the led light source (light-emitting-diode) of the power-type of the based semiconductor principle of luminosity that is celebrated with energy-saving and environmental protection, efficient long service life with and application surface facing market prospects greatly.But because led light source power is little in the past, light efficiency is low, price is high, the life-span is short etc.And the not high factor of the efficiency of light energy utilization; Be mainly used in low side fields such as traditional signal indication and family expenses flashlight; Can not dominate the market fully; The characteristics and the superiority that manifest it have a strong impact on and have limited its development and popularization, so large-power LED, especially are that development and the commercial application that influences the important accessory radiator of large-power LED life-span and quality seems more urgent and important to closing main.
See on the existing market with most of producers used LED radiators and be generally radiator other product customization or that increase area, and material is generally the very low die casting aluminium of coefficient of heat transfer.The former is the shared article of other products because of it, does not reach the requirement that LED needs quick heat radiating, from but the heat of LED can not leave, make the LED temperature surpass the junction temperature of itself device, quicken its light decay and have a strong impact on service life.The latter has requirement because of the LED heat radiation to area of dissipation; So its increase radiator area simply; Must also can and then thicken by thickness and increase area; Do not consider LED to radiator fast, heat dissipation technology requirement uniformly, and heat radiation is neither the big more radiating effect of area good more, (wherein relating to many-sided factors such as material, aerodynamics).Its another shortcoming is to increase cost greatly, has seriously influenced marketing, and has not reached actual demand.
(3) summary of the invention
Technical problem to be solved by this invention is to provide a kind of and cooperates with the large-power LED light source; And the heat that itself device is produced can fast, evenly distribute, and can effectively must reduce light decay, the luminous flux that improves light source and the LED radiator of life-saving.
A kind of large-power LED radiator, described LED radiator cross section is curved generally, and the arc radius is 150mm; Described LED radiator is formed around a center heat dissipation base by three annular radiating tubes; In said three annular radiating tubes; Innermost layer radiating tube internal diameter is 154mm for the 142mm external diameter; Intermediate layer radiating tube internal diameter is 197mm for the 185mm external diameter, and outermost layer radiating tube internal diameter is 234mm for the 228mm external diameter; Heat dissipation base front portion, described center is provided with the cylindrical cavity that is used to place led chip; Cavity diameter is that 70mm highly is 10mm; All circumferentially be evenly distributed with the rectangle fin of 36 radical lengths between center heat dissipation base and the outermost layer radiating tube; The width of fin is 3mm, and the heat dissipation base outside in center has several louvres; Described center heat dissipation base, radiating tube and rectangle fin are all handled through blackout.LED radiator of the present invention is by the plant equipment machine-shaping through precision of the aluminum of high heat conduction.
The present invention is owing to adopt the combination of a plurality of heat-sink units; Size through to each parts is optimized selection; The applied aerodynamics principle with process with the pure aluminum material of high conductance; Can cooperate with single or many high-power LED light sources, the temperature that can distribute device fast and effectively and produced, radiating effect is fairly obvious.Solve the too high problem of LED junction temperature simultaneously, an aspect such as LED service life, stabilised quality, minimizing light decay is all increased significantly.

(5) specific embodiment
Through embodiment the present invention is preferably specified below, but protection scope of the present invention is not limited to this.
With reference to Fig. 1; A kind of large-power LED radiator, described LED radiator is by three annular radiating tubes 2,3; 4 form around a center heat dissipation base 1, all circumferentially are evenly distributed with the rectangle fin 5 of 36 radical lengths between center heat dissipation base 1 and the outermost layer radiating tube 4.Said center heat-sink unit 1 can adopt inserted sheet to connect with being weldingly connected with radiating tube 2,3,4 and fin 5.
In said three annular radiating tubes, radiating tube 2 internal diameters in innermost layer are 142mm, and external diameter is 154mm; Radiating tube 3 internal diameters in intermediate layer are 185mm, and external diameter is 197mm; Outermost layer radiating tube 4 internal diameters are 228mm, and external diameter is 234mm.Said rectangle fin 5 width are 3mm.Described LED radiator cross section is curved generally, and the arc radius is 150mm.
Described center heat dissipation base, radiating tube and rectangle fin are all handled through blackout.Radiator of the present invention is by the plant equipment machine-shaping through precision of the aluminum of high heat conduction.
