ABSTRACT

The headlight glare becomes one of major causes for road accidents. This headlight glare causes the vision obstruction of opposite driver for a while which leads to minor or major road accidents. Out of average annual accidents due to headlight glare is about 30%. The current headlight system consists of either of the “Parabolic reflector or Narrow angled reflector (short focal distance), or Wide angled reflector (long focal distance). In these types of conventional reflectors, point source of light is converted into parallel light of beams then it is magnified i.e., light beam is diverged by using the concave lens, which leads to glare. The motto of the proposed project is to reduce the glare by using parallel beam headlight system. The system not only consists of parallel beams but also some amount of diverged beam to ensure downside visibility. This combined system leads to effective visibility of the objects and vehicles in the road area. The combined system consists of a parabolic reflector, filament, concave lens, protective torch glass. That is the single concave lens is replaced by protective torch glass and the concave lens which gives combined effect of both parallel and diverged beams.
