Lighting and/or indicating device equipped with a device for regulating the luminous flux for a halogen bulb

摘要

The present invention relates to a lighting and/or indicating device, such as a vehicle headlamp, equipped with at least one halogen bulb, wherein it comprises a switch-mode power supply device for supplying power to the halogen bulb, said switch-mode power supply device comprising means for regulating the luminous flux provided by the halogen bulb and being installed close to the halogen bulb so as to minimize electromagnetic interference and dispersion of the supply voltage at the terminals of the halogen bulb.

主权项

1. A lighting device, comprising: at least one halogen bulb, wherein each halogen bulb includes a cap; a connector for each halogen bulb, wherein the cap of each halogen bulb is mounted on each connector; and a switch-mode power supply device for each halogen bulb, each switch-mode power supply device being adapted to supply power to each halogen bulb and to regulate an output voltage from the switch-mode power supply device independent of a supply voltage to the switch-mode power supply device, each switch-mode power supply device comprising a regulating circuit for regulating the luminous flux provided by each halogen bulb, wherein each switch-mode power supply device is configured to minimize electromagnetic interference and dispersion of the supply voltage at the terminals of each halogen bulb whereby each switch-mode power supply device is integrated in one of the following manners: integrated in the cap of each halogen bulb, or integrated in each connector.
