A cold-cathode discharge lamp device including a cold-cathode discharge lamp unit and a supplemental light source for emitting light toward a discharge space between a pair of cold-electrodes of the discharge lamp unit for producing initial electrons in the discharge space.

Cold-cathode discharge lamp device

A rare gas discharge lamp device comprises a bulb with a rare gas sealed therein, a pair of internal electrodes provided within the bulb, a phosphor layer formed on the inner surface of the bulb, a lighting circuit adapted to apply voltage across two internal electrodes to produce a discharge or a positive column between the internal electrodes, and an auxiliary electrode formed on the outer surface of the bulb and extending in the longitudinal direction of the bulb, the positive column being attracted toward the auxiliary electrode, and a window formed on the bulb in a manner to face the auxiliary electrode for emitting visible light to be produced within the bulb.

Rare gas discharge lamp device

A socket for electrically and mechanically connecting a baseless lamp comprises a cylindrical main body having a peripheral wall and, a bottom wall to receive said one end of said lamp, engaging segments and an insulating engaging flange protruding from the outer periphery of the peripheral wall of the main body and capable of holding a printed wiring board therebetween, a groove and slot assembly for leading out lead wires of the lamp with one end inserted in the main body from the main body through said bottom wall and fixedly holding part of said lead wires on a surface of said engaging flange which faces said engaging segments.

Lamp holder for baseless lamp
