Evacuated glass bulb
WebThe next major bulb invention came in 1950 when English physicist Joseph Wilson Swan created a "light bulb" by enclosing carbonized paper filaments in an evacuated glass bulb. But the lifetime of the bulb developed by Swan wasn't long enough. The lock of a good vacuum and inadequate electricity supply led to the failure of the bulb invention.
