When you work with LEDs day in, day out, it’s all too easy to forget that LEDs and their close cousin, the solid-state laser, are actually quite wondrous. Think about it: You can connect these tiny devices up to a battery and they produce light, and not just one type of light. The wavelengths available span the far ultraviolet (UV) to the deep infrared (IR), and of course the visible range for humans. Moreover, the sources are available in a bewildering variety of sizes and power ratings. The areas of application for LEDs are expanding daily. LED TV remote controls have become LED TVs; LED torches have morphed into LED car headlights and now floodlights for sports stadiums; and new industrial products used in polymer curing, water purification, and horticulture are making tremen...
