Incandescent light bulbs were eliminated from the market rapidly,which promoted the transition of the traditional incandescent lamp and energy-saving lamp factory to the field of LED lighting,particularly,filament LED packing technology caused extensive concern of the industry.Microporous metal or glass was used as substrate,solid crystal and wire bonding at one side,LED filament realized the full angel of 360° glows.
