2, when adopting metal tube, guarantee metal tube have at least one side for the plane as contact plane, to settle LED lamp pearl, its cross section also can be triangle or quadrangle or polygon.The back side of LED lamp pearl directly is close on the contact plane that is fixed on metal tube, and the heat that the lamp pearl produces just can be delivered in the heat-absorbing medium in the metal tube by metal tube.
LED lamp pearl and radiating tube contact plane are generally taked mode bonding or welding, and the lamp pearl back side and contact plane are close to, to guarantee heat-transfer effect.
Described heat-absorbing medium is generally water, also can be oil or other heat absorption liquid, is that heat-absorbing medium absorbs the heat that LED produces when luminous and directly effectively heat taken away with the method that flows in principle, thereby reaches the cooling purpose.Heat-absorbing medium enters from the import of radiating tube, through the heat radiation pond from outlet out, can constantly replenish and recycle; Described heat radiation pond is a large open-top receptacle, and two is connected with entrance point and the port of export of radiating tube respectively, can be used as the heat radiation of heat-absorbing medium and additional usefulness.The import of radiating tube and outlet form the semiclosed circulatory system with the heat radiation pond of centre, after heat-absorbing medium is taken away lamp pearl heat, behind circulating path and heat radiation pond cooling heat dissipation, return lamp pearl position, and constantly heat is constantly taken away in circulation; Its circulation power can be provided by electric pump.Recycle more economize on resources cost and dependence to external world, be applicable to the work condition environment of highly dense high-power LED array.
The hot water of heat radiation in the pond can be used for daily life, and especially the hot water supply during winter is very convenient, as long as in time replenished running water after using.
LED lamp pearl can serial or parallel connection on radiating tube, heat-absorbing medium is taken away the heat that LED lamp pearl produces continuously, after tested, led array illuminator temperature in the present invention decides can not surpass local normal temperature (generally between the 10-26 degree, winter is lower) generally speaking according to local weather temperature.In particular cases, the radiating tube of large-area led array illuminator can directly spray cooling with running water, and the cooling Recovery and recycle uses.
In addition, can also near the position of illuminator temperature-sensing element be set in the outlet of radiating tube, the uninterrupted by the control heat-absorbing medium reaches constant temperature and more energy-conservation purpose.
Because the plasticity of plastics and metal, radiating tube can be made the intercommunicating container of arbitrary shape, make led array produce various style moulding, such as direct formation literal (enterprise name) or pattern (trade mark), make the present invention that more wide market prospects arranged.
In sum, the present invention is owing to having saved aluminium base, radiator (sheet), thermostat and air-conditioning, greatly saved cost (comparing saving 70% cost with monomer LED light fixture equal conditions on the market), and greatly reduced the volume and weight of illuminator, be more conducive to install and maintenance, because being dispels the heat in pipe rather than dispels the heat in air, even in the lamp box of sealing, use, cooling-down effect is also unaffected, simultaneously, the use of highly denser more large-scale led array illuminator is become a reality, so the present invention is that a kind of cost is low, easy for installation, life-span long (can reach the theoretical value of LED lamp pearl luminescent lifetime), pollution-free, the heat abstractor of the high-power LED array of good heat dissipation effect.
