PURPOSE:To obtain a low pressure neon discharge lamp that can mainly obtain emission of neon by containing a small amount of krypton. CONSTITUTION:In a discharge container that seals the mixed gas of neon and krypton, supposing that the sealing pressure of the mixed gas is P (Torr) and the krypton mixing ratio is A (%), a relationship of A<=8P<-2>(%) is satisfied. As a result, since the mixed gas of krypton and neon is used, the discharge start voltage can be reduced by Penning's effect. For example, for the pressure of 5 Torr, while the discharge start voltage of a lamp that seals single body of neon is approximately 135 V, that of a lamp krypton mixing ratio of 0.1% is reduced to approximately 110V. |
