Samenvatting
The development of headlamps was found to experience a dynamic process. For more than 50 years the tungsten double filament bulbs (Bilux) had been dominating the lighting technology, followed in the seventies by the H4 bulb. Since the middle of the eighties the modern filament bulbs as H7 (now H9, H11 ) have been available. The Xenon gas discharge (or HID-) technology reached the automotive market in the nineties. Now the development is heading towards the new technology step. Adaptive "intelligent" headlamps will bring the headlamp from its isolation in the front module back into the world of electronics and car networking systems. (A)
