Abstract

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.
