Title:
GAS DISCHARGE DEVICE, PLANAR LIGHT SOURCE USING SAME, AND METHOD FOR DRIVING SAME
Document Type and Number:
WIPO Patent Application WO/2016/125708
Kind Code:
A1
Abstract:
The present invention provides a gas discharge device that has a simple structure, is low-cost, and has good luminous efficiency, for an ultraviolet- or visible-light source. In the gas discharge device according to the present invention, first and second long electrodes (2, 3) extending towards either side along a longitudinal direction with a discharge gap interposed therebetween are provided on the outer side of a rear-side flat surface of a narrow glass tube (1) that has front-side and rear-side flat surfaces facing each other on a transverse section thereof and that contains a discharge gas sealed therein. Starting with a trigger discharge that is initially generated in the discharge gap as a result of a voltage increase when a sine-waveform or ramp-waveform voltage is applied between the two electrodes (2, 3), the discharge gradually extends so as to move in the longitudinal directions of the long electrodes (2, 3). Ultraviolet light having high luminous efficiency and light output power is obtained from the front-side flat surface by forming an ultraviolet phosphor layer in the narrow glass tube (1) and driving it with a sine-wave voltage.
