Validating a desired headlamp beam pattern traditionally requires the selection of an appropriate thermoplastic material for the complex reflector
, building prototype tooling for molding parts, and then determining the degree of reflector distortion under the extreme thermal conditions mandated during part testing.
Exterior lighting uses light-emitting diode lamps and complex reflector
Designed to make more efficient use of available light, Hitachi has developed a special polarization converter in combination with a complex reflector
light source designed to ensure that as much light as possible arrives to the LCD panel.
The projector also has a complex reflector
light source designed to maximize the amount of light reaching the LCD panel.
The change will come after a period of relative stability that saw the introduction of only occasional new technologies, such as halogen bulbs, complex reflectors
and high-intensity discharge lamps.
