PURPOSE:To obtain a low pressure neon discharge lamp that can mainly obtain emission of neon by containing a small amount of argon. CONSTITUTION:In a discharge container that seals the mixed gas of neon and argon, supposing that the sealing pressure of the mixed gas is P (Torr) and the argon mixing ratio is A(%), a relationship of A<=5P<-2>(%) is satisfied. As a result, since the mixed gas of argon and neon is used, the discharge start voltage can be reduced by Penning's effect. For example, for the pressure of 5Torr, while the discharge start voltage of a lamp that seals a single body of neon is approximately 135V, that of a lamp of argon mixing ratio of 0.1% is reduced to approximately 105V. |
