METHOD FOR MANUFACTURING AN ELECTRIC LIGHT BULB |
摘要 |
The invention relates to a method for manufacturing an electric light bulb containing at least one spiral-wound filament (31) and a dimmer cap (20). According to the invention, one end (31a) of a spiral-wound filament (31) is threaded in a notch (23) on the rim of the dimmer cap (20) and melted on to the dimmer cap (20). This is done by melting the material of the dimmer cap (20) in the area of the notch (23) so that the molten elements wet the spiralwound filament (31a) arranged in the notch (23) and the spiral-wound filament (31) is embedded in the solidified material (20a) of the dimmer cap (20)after the molten elements have hardened.
