New Lighting System for Electronic Analog Clusters 900675

The development of a high tech image analog cluster providing good readability is required by today's customer. To satisfy this trend, we have developed a highly unique analog cluster, which features very sharp white lit pointers with evenly illuminated white dials on a black acrylic face. These features are primarily achieved through two new lighting sources:1. Pointers made from thin, lightweight Cold Cathode Discharge Tubes. This pointer creates very high brightness, regardless of temperature, by enclosing xenon gas in the tube, and was designed into a single side electrode structure.2. Circular shape Cold Cathode Tube Installed Behind Each Dial Applique. This application creates very bright high quality illumination.In this session, we would like to introduce the construction and system of two new lighting sources for lexus, LS400. This technology provide improved readability.
