Title:
車両ランプ用LED制御装置
Document Type and Number:
Japanese Patent JP5085969
Kind Code:
B2
Abstract:
The device has a lighting module including a microcontroller for transmitting a unique signature representing a predefined range of a diode lamp. A receiving unit receives a current for powering the lamp, where the current is determined as a function of the signature. A control module e.g. driver, includes low-pass filter for receiving the signature and representing the predefined range of diode lamp. A transistor power circuit adjusts and supplies the current to the lighting module for causing the lamp to operate as a function of the transmitted signature. Independent claims are also included for the following: (1) a lighting module comprising a diode lamp for a vehicle light device (2) a control module for controlling a lighting module (3) a light device for a vehicle.
