HIGH-INTENSITY DISCHARGE LAMP |
摘要 |
<p>The invention relates to a high-intensity discharge lamp for a vehicle-light projector system, comprising a base (4) that carries an outer envelope (1) in which a burner (2) is arranged, the burner (2) comprising a discharge chamber (21) into which two electrodes (22, 23) project, the discharge chamber (21) being filled at least with an inert gas, a mixture of metal halides and a salt reservoir, the so-called“salt lake”(25). The outer envelope (1) has a coating (31) in strip form that screens off light and that extends, on the side of the outer envelope (1) adjacent the salt lake (25), for at least 40% of the length of the outer envelope (1) and whose width covers an angle of between 90° and 180° around the outer envelope (1). The invention also relates to a projector system for motor vehicle headlamps comprising at least one high-intensity discharge lamp of this kind.</p> |
