HEADLAMPS FOR THE FUTURE

THIS REVIEW CONSIDERS HOW DEVELOPMENTS IN LIGHT SOURCES ENABLE HEADLIGHT UNITS TO PRODUCE MORE ILLUMINATION WHERE REQUIRED, WITHOUT INCREASING GLARE EITHER FROM ONCOMING VEHICLES, OR FROM THOSE BEHIND REFLECTED IN THE DRIVING MIRROR. NOTABLE ADVANCES IN THE LAST FEW YEARS ARE DEVELOPMENTS IN SEALED-BEAM HEADLAMPS AND TUNGSTEN HALOGEN LAMPS, WHICH ARE FINDING INCREASING APPLICATION TO VEHICLE LIGHTING. MANUFACTURE IS NOW UNDER WAY OF A SEALED BEAM UNIT HAVING A TWIN-FILAMENT TUNGSTEN-HALOGEN INNER CAPSULE, INCORPORATING THE ADVANTAGES OF THE BRIGHTER TUNGSTEN HALOGEN LIGHT SOURCE WITH THE PRECISION FOCUSING OF THE SEALED BEAM CONSTRUCTION. /AUTHOR/
