Driving Vision News visited Koito and spent a day with management to better understand their strategy and their results. This week we present the range of LED headlamps and Koito’s targets for the future.
First go: LS600h headlamp launched in May 2007
Low beam is produced by 3 projector optical modules, each equipped with a 4-emitter light source array. All three projectors move together for AFS functions. There’s also a reflector with one 4-emitter and one 2-emitter light source array, for a total of 18 emitters and 50w consumption per side of the vehicle.
High beam is produced by a projector system making 2 functions, visible high beam and IR light for night vision. An IR-pass filter is shifted into the beam path for situations in which visible-light high beam cannot be used, according to the same principles as the cutoff shield shift in a BiXenon or BiHalogen projector.
