Lamp Technology

The electric light has caused me the greatest amount of study and has required the most elaborate experiments.—Thomas A. Edison

Some of the biggest advances in automated lighting technology have been in the area of optical systems. Computer-aided design of reflectors, lithographic techniques, and optical thin-film coatings have helped to improve efficiency, color saturation, and the clarity of image projection. But perhaps the biggest advances, and the area with the most potential for advances, are in the area of light source technology. Years of advances have led to the development of light sources with greater efficiency, longer average life, and better color rendering. New technologies like LEDs and plasma lamps ...
