An ignition unit (3) for igniting a discharge lamp (1), especially a high intensity discharge (HID) lamp or an ultra high intensity discharge (UHP) lamp, and a switch unit, which especially can be manually operated by a user, for switching on a discharge lamp is disclosed. Furthermore, a circuit arrangement for operating such a discharge lamp (1) comprising a lamp driver (21) and an ignition unit (3), and a discharge lamp unit comprising a discharge lamp (1) or lamp burner, preferably a reflector and such a circuit arrangement is described, which advantageously can be used due to a small volume and a small weight for example in ultra bright torches like Ujoy® torches or Ujoy® lamps or Ujoy® projection systems. |
