STEREOSCOPIC POWER SUPPLY OF BULB AND LED LAMP FILAMENT BULB

Disclosed is a stereoscopic power supply of a bulb, comprising a first substrate (1) and a second substrate (2), which are parallel to each other, wherein each of the first substrate (1) and the second substrate (2) is provided with an electronic device (4); the electronic devices (4) are electrically connected via lines on the substrates; the first substrate (1) and the second substrate (2) are electrically connected and fixed via a plurality of conductive columns (3); and a plurality of mounting holes (5) for mounting a lamp filament light source (8) are formed in the first substrate (1) and the second substrate (2), respectively. The stereoscopic power supply of the bulb has a smaller size so that the stereoscopic power supply can be placed inside a lamp holder; and the stereoscopic power supply is simple and convenient to mount, and the performance of the power supply is greatly improved.
