Discharge lamps have become common in automotive lighting due to advantages in efficacy, styling possibilities and lifetime. However, a major drawback is 'Electro-Magnetic Interference' (EMI) caused by currents and high voltages used for ignition and operation. Rear signal lighting is even more problematic than headlamp operation due to the proximity of radio antennas, which by definition pick up electromagnetic radiation perfectly. Several techniques have been evaluated to solve electromagnetic compatibility of AC driven gas discharge systems. Even for rear signal lighting, where high specifications exist due to closely mounted antennas, the requirements of car manufacturers can be fulfilled. An overall cost effective solution requires the introduction of these techniques in an early phase of the design. Important assumptions are antenna distance as well as car design to define the required shielding level. Experience of more than a million Luminon systems on the road has shown that EMI, if properly handled, should not be a drawback of gas discharge applications in automotive lighting.
