After several years of development, filament lamp by the world market of all ages. Whether it is North America, South America or Europe, the Middle East, Africa, Australia, Japan and South Korea, are outstretched arms welcome filament lamp.

Bidding filament lamp! Flexible LED(Flexible LED Filament bulbs GLS A19 FLEX) backplane with no flip-chip LED chips, such as blue LED chips, when the light-emitting yellow-green phosphor, exciting secondary light, showing white light. Yellow green phosphor powder mixed with the amount of red light can adjust the color temperature of the filament. Also available yellow, green and other LED chips to create yellow, green and other flexible color filament.
FPC is short for Flexible Printed Circuit. FPC flexible printed circuit is a kind of highly reliable and excellent flexible printed circuit made of polyimide or polyester film. Also known as flexible circuit boards, flexible printed circuit boards, flexible circuit boards, with wiring density, light weight, thin thickness.

Flexible LED(Flexible LED Filament bulb supplier china) Filament Copper clad polyimide film PFC as the base material, printed on the copper foil on the required connection lines and solder flip-chip mounting LED chip and etching. In the etched circuit of copper foil FPC substrate first coated with the underlying phosphor, so that the flip-chip LED surface blue penetration of white light. Paste flip LED chip, over reflow curing. The upper phosphor coating, and then heat curing. Yellow-green phosphor must be wrapped blue LED chip to prevent the blue light out.
