What is the principle of imitation tungsten filament led lamp? Thank you.

Hello, the working principle of imitation tungsten wire led lamp is the same as that of ordinary LED lamp, but the difference is that the packaging of lamp beads is different. The chip of ordinary LED lamp is encapsulated in a small bracket. The chip of tungsten-like led lamp is packaged on a long rod. At present, ceramics or sapphire are usually used. LED filament is a kind of light-emitting chip with different appearances, and the commercial power is rectified by the driving power supply and activated to emit light.
