ADAPTIVE LED HEADLIGHTS



INTRODUCTION

ADAPTIVE SYSTEM IN HEAD LIGHTS PROVIDES

IMPROVED VISIBILITY IN CURVES AT NIGHT.

LIGHT TRANSMITTING ANGLE CAN BECHANGED ACCORDING TO STEERING ANGLE.

ADAPTIVE HEADLIGHTS INCLUDES AUTO

DIPPING.

INCORPORATING LED LIGHTS PROVIDE BETTER

VISIBILITY.



OBJECTIVES

TO ENHANCE THE EXISTING FUNCTIONALITY.

IMPROVE VISIBILITY.

TO DECREASE THE NUMBER OF NIGHT TIME

ACCIDENTS.

TO INCREASE SAFETY FOR PASSENGERS &

PEDESTRIANS.



ADAPTIVE HEADLIGHTS



HOW IT WORKS..



IMPORTANCE

ACCIDENT RATES DURING NIGHT TIME ARE

THREE TIMES THAT OF DAY TIME.

CLEAR VISION WILL PROVIDE SAFTEY TO OWNVEHICLE,OTHER VEHICLES & TO PEDESTRIANS.

BETTER VISIBILITY IN CURVES DURING NIGHT

IS NECESSARY FOR SAFE JOURNEY.

AUTO DIPPER WILL REDUCE ACCIDENTS DUE

TO GLARE ON OPPOSITE CAR WIND SHEILD.



HISTORY OF HEADLIGHTS

FIRST HEADLIGHT WAS OIL BURNING LANTERNS.

CARBON FILMENT HEAD LAMPS .

CARBON FILAMENT REPLACED WITH TUNGSTENFILAMENT.

IDEA OF LOW BEAM & HIGH BEAM ESTABLISHED.

SEALED BEAM HEADLIGHTS WERE INTRODUCED.

REPLACED BY HALOGEN HEAD LIGHTS. HID LIGHTS & PLASTIC LENSES WERE

INTRODUCED.



EXISTING TECHNOLOGIES

SEALED BEAM HEADLIGHTS.

HALOGEN HEADLIGHTS.

COMPOSITE HEADLIGHTS. HIGH INTESITY DISCHARGE LIGHTS.



DRAWBACKS OF ORDINARY

HEADLIGHTS

THESE SYSTEM COULD NOT ACCURATELY

DISCERN HEADLAMPS FROM NON VEHICULAR

LIGHT SOURCES.

THEY DONT HAVE AUTODIPPER.

THEY CANT PROVIDE LIGHTING RELATED TO

DIRECTION OF MOTION.

THESE LIGHTS REQUIRES MORE POWER INPUT.

ADVANTAGES

LOW POWER CONSUMPTION.

BETTER VISIBILITY.

GLARE IS REDUCED BY THE ANGLE OF THEBEAM IN CURVES.

WILL CONTRIBUTE TO NEW AERODYNAMIC

DESIGNS. IMPROVED OPTICAL CONTROL.

REDUCES THE SIZE OF HEADLIGHT ASSEMBLY.



LIMITATIONS

HIGH INITIAL COST.

DEPENDS MORE ON ELECTRICAL CIRCUITS &

ELECTRONIC COMPONENTS.



CONCLUSION

THIS TURNS OUT TO BE AN EFFICIENT SYSTEM

FOR AUTOMOTIVE HEADLIGHTS .

IT HELPS IN REDUCING ACCIDENTS DUE TO

INCOVENIENCE CAUSED BY HEADLIGHTS

DURING NIGHT TIME.

IT ENABLES BETTER VISIBILITY WITHOUT

INTERFERING OTHER ROAD USERS.
