In the LED lighting lamps and lanterns market gradually into the white-hot stage, enterprises need to pragmatic pursuit: quality, technology, price, in order to share in the market!
In the performance of the product research and development of LED lighting lamps and lanterns must be forethought, exquisite craft, so how do you do on the product performance, keep enduring quality assurance?
This is not only what customers value, to the enterprise is also very important!
All know that the main components affecting the life of LED lighting lamps and lanterns is: radiator and drive power!
The LED lighting lamps and lanterns is one of the major technical problems in the heat dissipation problem, poor heat dissipation lead to LED drive power supply, electrolytic capacitor is short to the further development of LED lighting lamps and lanterns, the LED light source, the causes of premature aging.
Only by reducing export quantity of heat to be effective as soon as possible the cavity temperature inside the LED lamps and lanterns, can protect the power supply does not work in the persistent high temperatures, can avoid the LED light source for high temperature for a long time work and produce premature aging.
Because of the LED light source itself no infrared, ultraviolet, so the LED light source itself without radiation cooling function, the LED lighting lamps and lanterns of the cooling way only through close combination with LED lamp bead board heat radiator to export.
The radiator must possess the function of the heat conduction, convection and radiation.
Any radiator, in addition to can quickly to the heat from the heat source conduction to the surface of the radiator, the main or rely on the heat convection and radiation in the air.
Way only solves the heat transfer of thermal conductivity, and heat convection is the main function of the radiator, the heat dissipating performance mainly by natural convection heat dissipation area, shape, strength the ability of the decision, the effect of thermal radiation is auxiliary.
In general, if the heat from the heat source to the radiator surface distance is less than 5 mm, so as long as the material coefficient of thermal conductivity is greater than 5, the heat can be derived, and the remaining heat must be dominated by heat convection.
Most of the LED lighting light source still use low voltage (
VF＝3．2V）
And big current (
如果= 200 - 700 ma)
commercial ceiling lamps bead, due to the high quantity of heat at work, you must use a higher coefficient of thermal conductivity of aluminum alloy.
Usually has a stamping die casting aluminum radiator, extruded aluminum radiator, aluminum radiator, cold forging radiator.
1, die-casting aluminum radiator technology is a kind of pressure casting parts, poured liquid zinc copper aluminum injection into the mouth of die casting machine, the die casting machine die casting, casting out the shape of the mould qualified radiator designed.
This process cost is low, but the heat dissipation wing cannot do thin, surface oxidation treatment can't do, can only use spray paint technology, so it is difficult to maximize the heat dissipation area.
The LED die casting material for ADC10 and ADC12 commonly used lamps and lanterns of the radiator.
2, extruded aluminum radiator is the liquid aluminum through fixed die extrusion, then put the rod by machining cutting into the shape of a need to radiator, post processing cost is higher.
Heat dissipation wing can do a lot of very thin, the heat dissipation wing work automatically when the air convection heat diffusion.
Commonly used material is AL6061 and AL6063.
3, punch and die for stamping aluminum radiator is made by steel, aluminum alloy sheet metal stamping, pull to rise, make a cup of tube type of radiator, stamping molding radiator inside and outside perimeter smooth, because there was no wings and the cooling area is limited.
Commonly used aluminum alloy material is 5052, 6061, 6063.
Stamping parts quality is small, high material utilization, is a low cost solution.
4, cold forging, radiator is pure aluminium billet in precision cold forging die in, produced by the press during plastic deformation, only end and blade arc need CNC lathe processing, save valuable raw materials and processing time, reducing the production costs, unique heat dissipation structure design, increase the cooling area larger extent, make this product work for a long time, under the status of the cup body temperature can keep below 50 ℃, thereby effectively reducing the LED light use process failure, to ensure that the quality of the lamps and lanterns.
According to the measured, as well as the size of the LED lamp cup, cold forging radiator cooling effect more than twice higher than that of die casting, more than a third higher than that of aluminum heat dissipation effect, another cold forging heat sinks more than a third lighter than the weight of the die casting shell, especially the larger volume of LED lamps and lanterns of export, freight can save a lot of yo!
Nowadays, it is very common for us to utilise in outside led downlights. And the quality of is decisive to production efficiency.
