Title (EN) GLOW DISCHARGE LAMP
(FR) LAMPE A DECHARGE LUMINESCENTE
Abstract:
(EN) A glow discharge lamp includes a light-transmitting envelope containing a rare gas fill material. The envelope contains a spherical-shaped region having a predetermined internal radius R. A phosphor coating is disposed on the inner surface of the envelope. Anode and cathode electrodes are disposed within the envelope and spaced a predetermined distance (d) thereapart. The voltage drop of the cathode electrode is less than the excitation potential of the rare gas fill material. The anode electrode has a predetermined effective surface area Sa such that the relationship Rd/Sa is within the range of from about 5.0 to 11.0.
(FR) Lampe à décharge luminescente dotée d'une enveloppe de transmission de la lumière contenant comme matériau de remplissage un gaz rare. Ladite enveloppe comporte une zone en forme de sphère ayant un rayon R interne prédéterminé. Un film de phosphore est déposé sur la surface interne de l'enveloppe. L'anode et la cathode sont disposées au sein de l'enveloppe et espacées l'une de l'autre d'une distance prédéterminée (d). La baisse de tension de la cathode est inférieure au potentiel d'excitation du gaz rare. L'anode comporte une surface effective prédéterminée Sa telle que la relation Rd/Sa se situe dans un fourchette allant d'environ 0,5 à 11,0.
