Beschreibung
Zusammenfassung:	A filament lighting apparatus includes a base, a pillar, multiple lamp strips, a fixed metal strip, a driving circuit and a lamp cap. The lower end of the pillar connects to the base. Each lamp strip has an upper end point and a lower end point. The upper end point of the lamp strip is electrically connected to the fixed metal strip. The fixed metal strip is disposed about an upper end of the pillar and the fixed metal strip doesn't directly contact the pillar. The lower end of at least two of the lamp strips are electrically connected to the driving circuit. The lamp cap accommodates the driving circuit and supports the base. The present invention discloses a method of manufacturing the filament lighting apparatus.
