A compact fused silica, electroded HID lamp for automotive forward lighting, which contains no mercury. The lamps voltage, approximately 40 volts, is developed in this lamp by vaporizing zinc iodide instead of mercury. A compromise between voltage and luminous flux is achieved through the choice of the sodium scandium (Na:Sc) molar ratio, between 4.5:1 and 6:1 and a zinc iodide (ZnI2) dose of 2 to 6 micrograms per cubic millimeter that permits the lamp to operate within the North America, European and Japanese automotive color specifications for white light. The voltage in the lamp can be controlled according to the zinc iodide doping level without seriously impacting the visible spectrum otherwise provided by the other known dopants in the lamp.

Phare HID à électrodes compactes de silice fondue, sans mercure, destiné à être monté sur les véhicules automobiles pour l'éclairage avant. La différence de potentiel de 40 volts est obtenue dans le phare par vaporisation d'iodure de zinc au lieu de mercure. On arrive à un compromis entre la différence de potentiel et le flux lumineux en ajustant le ratio molaire du sodium au scandium (Na:Sc) entre 4,5:1 et 6:1, et en fixant la dose d'iodure de zinc (ZnI2) entre 2 et 6 microgrammes par millimètre cube, ce qui permet au phare de fonctionner à l'intérieur des normes nord-américaines, européennes et japonaises en matière de spécifications de couleur pour la lumière blanche émise par les automobiles. La différence de potentiel dans le phare peut être modulée avec la concentration de dopage en iodure de zinc sans effet notable sur le spectre visible produit par les autres dopants connus dans le phare.
