Scope of the platform

The “g-Brake Lights” platform is an add-on brake lamp useful as an additional warning light

to increase safety in motorbike use, but just a few changes enable it to be used in other

kinds of vehicles. This solution is capable of increasing vehicle safety levels especially in

situations requiring a fast braking light response. In fact, the light intensity of the brake light

can be adapted to the braking intensity.

Moreover, compared to traditional incandescent bulb solutions, the main advantages of this

platform are:

●

the very short switch-on time

●

the low power consumption due to low power devices and the efficient conversion of

electrical power into optical power

●

the high lifetime of the optical actuator (for optimized LEDs, up to 100.000 hours)

A brief overview of the g-Brake Lights main blocks and characteristics follows.
