Abstract

Abstract A lighting apparatus for a neon lamp includes a direct current power supply with a relatively low voltage output. The direct current power supply actuates a pulse oscillator to produce a narrow pulse voltage train output. The narrow pulse voltage train output is amplified and is supplemented by the signal output of a glow control cirucit to drive the neon lamp into operation. The signal output of the glow control cirucit can be a pulsating voltage signal or a constant voltage signal to correspondingly cause the neon lamp to blink or glow constantly.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 131 words
A lighting apparatus for a neon lamp, comprising: direct current power supply means having an output voltage between 6 and 24 volts; pulse oscillator means actuated by said direct current power supply means to output a narrow pulse voltage train output; amplifying means to amplify said narrow pulse voltage train output; and glow control means having a signal output to supplement the amplified said narrow pulse voltage train output to drive said neon lamp into operation, said signal output being selectable between a pulsating voltage signal output and a constant voltage signal output; said neon lamp having a blinking light output when said signal output of said glow control means is pulsating, said neon lamp having a constant light output when said signal output of said glow control means is constant.
Claim 2
