Document Type and Number:
Japanese Patent JP2008507814
Kind Code:
A
Abstract:
A discharge lamp having a tube-like envelope ( 1,3 ) comprising an electrode ( 4 ) near at least one of the two ends of the envelope. The axis ( 5 ) of the electrode ( 4 ) is directed substantially perpendicular to the axis of the tube-like envelope ( 1,3 ). The ends of two pinch lead wires ( 7 ) are connected to the ends of the electrode ( 4 ) and a portion ( 10 ) of each pinch lead wire ( 7 ) is embedded in the material of the envelope ( 1,3 ). The electrode ( 4 ) is located nearer to the end of the tube-like envelope ( 1,3 ) than a part of the pinch lead wire ( 7 ) that is embedded in the material of the envelope ( 3 ), resulting in a uniform light emission up to almost the end of the envelope.
