GAS DISCHARGE LAMP WITH CONTROLLABLE LENGTH OF ILLUMINATION, METHOD OF DISCHARGE LENGHT CONTROL AND APARATUS FOR INDICATING BREAKING DECELERATION

摘要

An elongated gas-discharge lamp having a controllable illuminated length may be formed with a dielectric barrier discharge, in which the position of a discharge voltage is dependent, for example, on a discharge gap 6' which varies over the length of the lamp 1'. The varying discharge gap allows, for example, bar displays or quantitative brake warning lights to be provided.
