In the thesis, we use high-power white-light LEDs to be the light sources and present two types of bike lamp. In the simulation, we use Germany bike lighting rules (StVZO 22A No.23) as regulations. There are two advantages for the bike lamps:high contrast of the light pattern and broad lighting on the roadway. In addition, one of the two types of bike lamp also applies to two different LED light sources. Finally, we verify the validity of the two types of bike lamp with the prototypes.
