摘要:
The invention relates to a halogen bulb comprising two filaments that are located (21, 22) in a lamp body (10), a first filament (21) being designed for operation at a higher electrical output than the second filament (22). To fulfil a daylight driving function, the second filament (22) is designed to produce an electrical output that is lower by a factor of 2.5 to 4 than the electrical output of the first filament (21) when operating with a standard operating voltage and is designed in such a way that it can be operated with an operating voltage that is lower than the standard operating voltage in order to produce a dimmed position light function.
