LED Stadium Lights,The so-called transparent electrode is to be able to conduct electricity, the second is to be able to transmit light.This material is now more widely used in liquid crystal production process, its name is indium tin oxide, ITO, but it can not be used as a welding pad.Ohm electrode should be made on the surface of the chip first, and then covered with a layer of ITO and coated with a layer of welding pad on the surface of ITO.In this way, the current coming down from the lead is evenly distributed on each ohmic contact electrode through ITO layer. Meanwhile, the refractive index of ITO is between the refractive index of air and epitaxial material, which can improve the light output Angle and increase the luminous flux.
