Short Arc Metal Halide Lamp with New Ingredients for LCD Projector

Abstract

A new metal halide lamp employing gadolinium-lutetium iodide additives for LCD projector usage has been developed. Emission from gadolinium-lutetium iodides contributed to a significant improvement of various color characteristics. The new additives also led to a longer lifetime of the lamp. Besides, the designing of a reinforced arc tube has been realized through the fracture behavior analysis, providing a highly reliable arc tube.
