Practical and the commercialization of high performance lED, makes lighting engineering face a new revolution.The pixel lamp be made up of red, blue, the green three-color LED of multiple super brightness not only can send the continuously adjustable various coloured light of wavelength, but also the white light that brightness can reach tens to one hundred candle light can be sent become lighting source, for incandescent lamp and the LED solid lighting lamp of identical luminosity, the power consumption of the latter only accounts for the former 10%-20%.
The white light LEDs major part of current production is made by covering the faint yellow fluorescent coating of one deck on blue-ray LED, and this yellow phosphor is normally made by being blended in a kind of dense adhesive after the yag crystal mixing cerium is clayed into power.When LED chip sends blue light, some blue light just can be converted to the wider light being mainly yellow of a spectrum by this crystal very efficiently, because gold-tinted can stimulate ruddiness in naked eyes and green glow acceptor, then mix the blue light of LED itself, make it seem just as white light.
Existing LED is generally be directly installed on installing plate, installing plate is generally laminated structure, comprise three layers: the line layer being used for connecting up under the heat dissipating layer being used for dispelling the heat, the insulating barrier being used under heat dissipating layer insulating, insulating barrier, wherein heat dissipating layer is generally aluminium foil or aluminum alloy sheet; Line layer is generally Copper Foil and makes, and is used for doing configuration.LED is arranged on heat dissipating layer, welds with line layer.The installing plate heat dispersion of the LED of this type depends on the thermal conductance index of insulating barrier to a great extent, and the thermal conductance index of insulating barrier is often not high, causes the heat dispersion of whole LED installation strip not good.
