The spiral filament comprises a spiral substrate, and an LED chip and a conductive component which are arranged on the spiral substrate.
Such as shaped coiled-coil filaments made from a rigid substrate. The substrate in the filament adopts a flexible substrate or a rigid substrate, the rigid substrate can adopt a PCB or an aluminum substrate, and the flexible substrate can adopt an FPC substrate.
If a rigid substrate is adopted, after the spiral filament with the spiral structure is prepared, the shape of the spiral filament is fixed, deformation cannot occur, and the two ends of the spiral filament are directly fixed on the lamp cover and the lamp base.
If a flexible substrate is used, the coiled filament with a coiled structure can be elastically shaken, inclined or deformed. A sizing rod 5 may be provided in the middle of the coiled filament, the sizing rod passing through the middle passage of the coiled filament.

In this embodiment, the light emitting particles and the conductive member are both located in the light transmissive protective layer to form a filament shape.
The LED chip in this scheme is different from traditional LED lamp pearl, and the difference on the filament finished product of producing is great, because the lamp pearl is the LED chip that has been capsulated, and the outside can be equipped with the one deck thicker packaging layer, when making filament or lamp line into it, the defect has: 1) The distance between the two luminous particles is larger, when the two luminous particles are connected in series or in parallel to form a straight line, the weak light intensity of the gap can be obviously seen after the two luminous particles are lightened, so that the lamp effect of the whole lamp line can be changed into the connection of point light sources, and the filament is not a complete filament which can not be distinguished by naked eyes due to the difference of the light intensity. 2) Because the volume of LED lamp pearl compares in LED chip and needs a lot of greatly, when connecting, the cross section broad can't realize the effect of "filament", and the technical level is coarser, can not reach the luminous effect of filament after further making into the lamp line. And the use of LED chips can solve this problem well.
