Abstract:
1. A segmented brake light for a vehicle, comprising: a detecting module detecting pressure on a brake pedal of the vehicle to produce a detecting signal based on the detected pressure; a driving module producing a driving signal according to the detecting signal, and comprising: multiple voltage boosting circuits, each of the voltage boosting circuit having a power input terminal, an output terminal and a trigger terminal; a first comparing circuit having an input terminal connected to the detecting module and an output terminal connecting to the trigger terminal of one of the voltage boosting circuits; an electronic switch connected to an operating voltage and the power input terminal of another one of the voltage boosting circuits; a second comparing circuit having an input terminal connected to the output terminal of the first comparing circuit through the electronic switch; and multiple light modules connected to the output terminals of the voltage boosting circuits of the driving module and being selectively activated according to the driving signal.
