PROBLEMS AND SOME FINDINGS WITH POLARIZED HEADLIGHTS

Publisher Summary This chapter discusses a few problems and findings with polarized headlights, and describes the meeting conditions and the freeway driving conditions of the polarized lights. The efficiency of the polarized light must be much increased to give a good seeing distance by freeway driving. There is no use to take a lamp with higher wattage because a darker polarizer can then be necessary to prevent glaring. A headlamp with a larger diameter gives a better efficiency; however, the only way to get a real increase in efficiency is to make it possible to add the half part of light, which oscillates in right angle to the polarized beam. The chapter presents a comparison of polarized light and conventional light.
