Abstract:
A mercury-free gas discharge lamp suitable in particular for motor vehicles has an enhanced discharge arc diffuseness. The lamp according includes an inner vessel and/or outer bulb with a structured arrangement or pattern such that the discharge arc diffuseness of the lamp is increased, such as by 0.01 mm to 1.5 mm.
