BURNER WITH REDUCED HEIGHT AND METHOD OF MANUFACTURING A BURNER

摘要

It is provided a burner (12) for automotive lamps (10), particularly HID lamps, comprising a discharge vessel (14) for generating light by means of a discharge arc. A first electrode (16) terminates in the discharge vessel (14). A second electrode (18) terminates in the discharge vessel (14) for generating the discharge arc in cooperation with the first electrode (16). A glass body (20) for protecting the discharge vessel (14) is provided. The glass body (20) comprises a shaft (22) for being inserted into a socket (24). The first electrode (16) is led through the shaft (22) out of the glass body (20) in a proximal direction (32) and the second electrode (18) is led spaced to the first electrode (16) outside the shaft (22) in proximal direction (32). The shaft (22) comprises at least one insulation pocket (26) for receiving a rib (36) of the socket (24) and for insulating the first electrode (16) outside the glass body (20). Due to the insulation pocket (26) the glass body (20) may provide an umbrella-like dielectric increasing the minimum necessary way for a high voltage discharge arc between the uncovered part of the first electrode (16) at the proximal end of the shaft (22) and the second electrode (18) or other conductive parts. Due to the improved insulation effect by means of the insulation pocket (26) the height of the shaft (22) of the glass body (20) may be significantly reduced leading to a reduced height of the burner (12) without impairing the insulation of the burner (12). The total height of an automotive lamp (10) comprising this burner (12) can be reduced which in turn enables a further optimization of the required building space of the automotive headlight (56).
