<p>To obtain effective luminance and light efficiency while avoiding discharge, it is necessary to sufficiently increase a current luminous efficiency of gas and an electron emission efficiency of an electron source. In a fluorescent lamp, an anode electric field is increased by setting a pressure of a noble gas or a molecular gas enclosed to 10 kPa or higher, setting an anode voltage to 240 V or lower, and setting a substrate distance to 0.4 mm or smaller. Furthermore, the resulting effect that the current luminous efficiency is increased in proportion to the electric field is used. Also, by applying a MIM electron source having an electron emission efficiency exceeding 10% as an electron source, a non-discharge fluorescent lamp having a light emission luminance equal to or larger than 10 4 [cd/m 2 ] and a light emission efficiency equal to or larger than 120 [lm/W] is achieved.</p> |
