DIP LED tube is a kind of tube adopts DIP package, which is short for dual in-line package technology. It is a dual entry cable package widely used in DRAM components. When refers to the form of dual in-line package applied in integrated circuit chip, most of them are small and medium scale integrated circuits, the pins are generally not exceed 100. DIP LED tube is composed of an aluminum alloy light body and a PC cover. Traditional T5/T8 fluorescent tubes work with inductance ballast, which might cause problems like large power consumption, great heat emission, wink start-up, low power factor, tube replacement, ballast, starter frequency, and only have a 6000 hr life span. However, DIP LED tube, adopted SMD LED as light source, which is a new generation of green environmental protection product with lower power consumption and advantages of light weight, small size, long life expectancy, and durability. The brightness of DIP LED tube is 3-4 times higher than that of traditional fluorescent ones. So DIP LED tube is widely used in commercial and residential applications, emergency lighting, reading and task lighting, interior design uses, store displays, closet illumination, cove lighting, shopping mall illumination, parking lots, billboard illumination edge lighting, under counter lighting, backlight, office illumination and so on.
