LED foot packages using the lead frame for a variety of packaging appearance of the pin, was the first to successfully launch package structure, breed is numerous, technical maturity is high, inside the package structure and the reflecting layer is still in continuous improvement. Standard LED was most customers think is the display industry is the most convenient, the most economic solution, typical of traditional LED placement in can bear 0.1W input power of the envelope, the 90% heat is produced by the cathode pin rack distributed to PCB plate, and then is sent into the air, how to reduce the work of PN junction the temperature rise is encapsulated and application must be considered. Encapsulation materials using high temperature curing epoxy resin, its excellent performance, good adaptability, product reliability, can be made of colored transparent or colorless and transparent colored or colorless scattering lens package, different lens shapes to form various shapes and dimensions.
Different Packaging Structures of LED T8 Tubes
Color point light source has a variety of different packaging structures: the ceramic base epoxy resin has good temperature performance, the pin can be bent into a desired shape, small volume; metal base plastic reflecting cover package is a kind of energy-saving lamp, suitable for power indication; flashing type CMOS oscillating circuit chip and LED tube core combination package, can generate a strong visual impact of flashing light; double color by two different color led t8 tubes core, encapsulated in the same epoxy resin lenses, except for two color can also obtain third mixed color, in the large screen display system is widely used, and package composition double color display device; voltage type constant current source chip and LED tube core combination package, can be directly replaced the 5 - 24V and various voltage indicator lamp.
T8 LED Tube Display
LED light emitting display by the digital tube or pipe, tube, m character symbol matrix tube composed of a variety of many products, from the actual needs of the design into a variety of shapes and structures. The t8 led tube as an example, a reflection cover, monolithic, a seven section three kinds of packaging structure, connections are common anode and cathode two, a is usually said that digital tube, two or more generally referred to as display. Reflection type with large fonts, material saving, flexible assembly of hybrid packaging features, usually with white plastic with a reflective cavity made of seven segment shaped shell, a single LED tube core bonded with reflective cover seven reflection cavity and mutually aligned PCB panels, each reflecting cavity at the central position of the bottom is the tube core formation the light emitting area, with the pressure welding method of bonding wire, the reflecting hood drop in epoxy resin glue, and the core of the PCB board aligning bonding, and then cured to form.
