Title:
DISCHARGE LIGHT-EMITTING DEVICE AND METHOD OF MANUFACTURE THEREOF
Document Type and Number:
WIPO Patent Application WO/2001/056053
Kind Code:
A1
Abstract:
A discharge light-emitting device includes a gas-filled discharge spaces (30) to use electric discharge in the gas. The gas contains at least 0.01 - 1% water vapor by volume. The specified amount of water vapor decreases discharge voltage markedly. Water vapor is introduced between a sealing step and an evacuation step so that the gas-filled discharge spaces can finally contain a desired amount of water vapor.
