The ways of LED lamps package
The ways of LED lamps package are various according to different kinds of application scenes, sizes, cooling plans and illumination effects. At present, the ways of LED package mainly are DIP-LED, SMD-LED, High-Power-LED etc.
DIP LED In early stage, DIP LED was in-line LED and was embedment package. Here is the producing process. Liquid epoxy resin is injected in LED molding cavity firstly, and then LED bracket which has been welded is stabbed into the epoxy resin. After that, it is put into an oven for epoxy resin solidifying, and LED is separated from the molding cavity and done. Because of its relatively simple producing process and low cost, DIP LED has a high market share.
SMD LED SMD LED which is attached to the surface of circuit board is suitable for surface mounted technology processing and it can be reflowed. It is very good to handle a series of problems that include: the brightness, the perspective, the smoothness, the reliability, the consistency and so on. Because it has chosen a lighter PCB plate and refection layer material, it has removed in-line LED heavy carbon steel pins and used lesser epoxy resin in reflective layer, it can easily save half size and weight. In this way, it can be used much more flexible.
High Power LED In order to get high power and high brightness LED, LED manufacturers are devoted to developing high power LED chip and package. There are several watt power LED package technologies at present. The layout of package technology for Norlux series high power LED is multiple chips combination. And the hexagonal aluminum as the base is not conductive. The high power LED which base diameter is 31.75mm, diameter is (0.375*25.4)mm and illumination zone is in its center can contain 40 LED tube cores. Meanwhile, the aluminum plate is as the heat sink. This package has chosen the convention tube cores which are highly density assemble. Furthermore, it is high power, low high thermal resistance, and it has a high light output at high current. Therefore high power LED is a solid LED light source with great future.
