PURPOSE: A cold cathode tube type discharge lamp for linear speed control of a radiation field is provided to improve productivity using minute nano graphite powder ink. CONSTITUTION: An electrode cup (4) is inserted into the inner side of a center portion of a discharge lamp tube (1). An electrode is protruded to the inner side of the electrode cup. The electrode is drawn out to the outside of the discharge lamp tube. A graphite conductive film (3) is formed with the coating of minute nano powder graphite ink. A discharge lamp control circuit controls the linear speed of a radiation field. [Reference numerals] (10) Discharge lamp control circuit |
