摘要： The invention describes a method of driving a gas-discharge lamp (1) according to conditions in a specific region (R) of the lamp (1), which gas-discharge lamp (1) comprises a burner (2) in which a first electrode (4) and a second electrode (5) are arranged on either side of a discharge gap, which lamp (1) is realised such that the position (PCs) of a coldest spot during an AC mode of operation is in the vicinity of the first electrode (4), which method comprises the steps of initially driving the lamp (1) in the AC mode of operation; monitoring an environment variable of the lamp (1), which environment variable is indicative of conditions in a specific region (R) of the lamp (1); switching to a temporary DC mode of operation at a DC power value on the basis of the monitored environment variable, whereby the first electrode (4) is allocated as the anode; and driving the lamp (1) in the DC mode of operation until the monitored environment variable has returned to an intermediate environment variable threshold value (TDCAC). The invention also describes a gas-discharge lamp and a driver for a gas-discharge lamp.

摘要： It is provided a burner for automotive lamps, particularly HID lamps, comprising a discharge vessel for generating light by means of a discharge arc. A glass body for protecting the discharge vessel comprises a shaft for being inserted into a socket. The shaft comprises at least one insulation pocket for receiving a rib of the socket and for insulating the first electrode outside the glass body. Due to the insulation pocket the glass body may provide an umbrella-like dielectric increasing the minimum necessary way for a high voltage discharge arc to the uncovered part of the first electrode at the proximal end of the shaft. Due to the improved insulation effect by means of the insulation pocket, the height of the shaft of the glass body may be significantly reduced leading to a reduced height of the burner without impairing the insulation of the burner.

摘要： A method of generating a measuring signal indicating arc straightness in a gas discharge lamp (L) comprises the following steps: in a first step, applying a first lamp current (IN) to the lamp; in a second step, adding a brief pulse current (Ip) to the first lamp current (IN), allowing the lamp voltage to regain a steady state, and measuring the resulting average value of the lamp voltage (V2) in this steady state; generating a measuring signal indicating arc straightness on the basis of said average lamp voltage (V2) measured in the second step.
