Abstract

The electrodes of a flat panel cold cathode discharge lamp are each formed from a block of metal with holes arranged side-by-side along the electrode which open into the gas-discharge volume of the lamp. The holes extend at an angle of about 25-35 degrees away from the normal to the surface of the electrode and are formed by laser machining.
