Zusammenfassung: | The utility model discloses a halogen tungsten lamp with a glass stand, which comprises a bulb shell, an exhaust pipe arranged at the top end of the bulb shell, a clamping plate arranged at the lower end of the bulb shell, two molybdenum pieces encapsulated in the clamping plate, and a pair of base pins inserted into clamping pieces, wherein a fixed glass stand is arranged in a middle position in the bulb shell; the bottom end of the glass stand is fixed on the bulb shell. Two filaments are connected through the glass stand; one end of each filament, through a filament pin, is connected with the molybdenum pieces after welded with a tantalum piece in a transition mode; the other end of one filament and the other end of the other filament are mutually connected in series through the stand. One end of each base pin is electrically connected with the molybdenum pieces. The lamp bulb structure of the utility model is simple; the halogen tungsten lamp uses glass as the stand to save large numbers of molybdenum wires used as the stand; the technology assembly process is short; the production cost is reduced by 50%. |
