In 1891 Gerard Philips established a light bulb factory in Eindhoven with the aim of producing carbon wire filament incandescent light bulbs.The fittings and bulbs come from other factories, but Philips produced the carbon wire in-house.Carbon filament lamps were the first incandescent light bulbs, in which a filament emits light when heated by an electric current.The filament must be kept in a vacuum to prevent it from burning up,and this is why the filament is enclosed in a glass bulb.
