LED lamp radiator
Technical field
The present invention relates to a kind of lighting field, relate in particular to a kind of radiator that is applicable to high-powered LED lamp to dispel the heat.
Background technology
Along with the continuous progress of economic development and society, accelerate the depletion rate of resource and caused the in short supply of resource, restricting accordingly the paces of economic development and social progress, therefore, energy-conservation one of the important goal that enterprise pays close attention to that becomes.
Wherein, in lighting field, because a traditional crow silk lamp exists that energy consumption is large, the life-span is short and the defect such as not environmental protection, therefore for good condition is created in the development of new energy-saving lamp, and LED light fixture occurs under the condition based on above-mentioned just, due to LED light fixture, there is the advantages such as energy-saving and environmental protection and life-span length, therefore it is more and more subject to people at lighting field, favor.
As everyone knows, LED light fixture can produce a large amount of heats while using, if these heat energy can not be discharged timely, can restrict the illumination effect of LED light fixture, thereby have influence on the ordinary life of LED light fixture, especially for high-power LED light fixture, above-mentioned phenomenon is more obvious, therefore, the effect of radiator in LED light fixture is even more important.
High-power LED lamp in the market, adopts the aluminum component of die cast or extrusion modling as radiator more.The radiating fin of die cast radiator must design to such an extent that thicklyer just can produce, so this class radiator is all very heavy; When the power of LED light fixture surpasses 100 watt-hours, the special English full name of COB(that uses is: Chip on Board, Chinese full name is: chip on board encapsulation) pattern LED and high heat density LED module are made light source, the heat that LED produces must rapid diffusion be gone out, otherwise the junction temperature of LED can be very high, efficiency will significantly decay, even burn out LED, but die cast radiator is owing to being with the low die casting class aluminium of thermal conductivity, thermal diffusion is slow, so even if radiator is done very greatly, heat still can overstock at LED, and the temperature of LED is high, efficiency is low, and the life-span is short.And extrusion modling radiator is aluminium section bar, moulding is dull, has seriously limited the profile of light fixture, and this radiator is subject to the restriction of production equipment, and appearance and size can not be done greatly, and the power of LED light fixture has also just been limited.
For further realizing better radiating effect, adopt in addition the aluminum alloy flake of punching press to be used as radiating fin, this radiator is conventionally at the more radiating fin of surrounding's assembling of a pedestal, area of dissipation is significantly increased, but this radiating fin is assembled in pedestal technique around and is not easy to implement, often because combined structure design is reasonable not, the phenomenon such as cause in assembling process easily coming off or become flexible, and radiating fin and pedestal joint have larger temperature fall, affect radiating efficiency.
Therefore, be necessary to provide a kind of assemble simple and quick, production cost is low and the high-power LED (Light-Emitting Diode) lamp radiator of good heat dissipation effect to solve the deficiencies in the prior art.
