Abstract
A luminous sign (10) comprising three sandwiched plates: a front transparent legend plate (12) incorporating a legend (12a), a center feedthrough plate (14) having a set of termination bores (14a) and crossover bores (14b), and a back crossover cavity plate (16) having a first and second power/gas input bore (16b) (16c) and a crossover cavity (16a) across each set of crossover bores (14b). When all three plates are aligned and hermetically bonded a continuous gas passage is provided through the first power/gas input bore (16b), termination bore (14a), legend (12a), crossover bore (14b), through the crossover cavity (16a), a crossover bore (14b) and again through the legend (12a). The gas path continues through subsequent passages terminating at the second power/gas input bore (16c). Into the power/gas input bores (b 16b) (16c) is hermetically inserted a tubulated electrode (18) and a non-tubulated electrode respectively. When neon gas is captively inserted into the tubulated electrode (18) and electrical power is applied to the electrodes, the gas ionizes causing the legend (12a) to glow.
