Multi-die LED arrays are changing LED strobe lights. A multi-die array LED product can contain 50 to 100 LEDs on a single housing. Using hundreds of small high power LEDs or multi-die LED arrays in a strobe light output, it can outperform existing high output lights including halogen, metal halide and even xenon flash lamp.
Xenon flash lamps have a short duration of active light strobe time. Common flash lamp strobe lamps have duration times of six to 30 microseconds. An LED can be strobed for any duration that is within the safe limit of current as long as heat is managed. The shorter the strobe time, the more power the LED can be over driven producing more light intensity. If an LED light is strobed for a hundred or even hundreds of microseconds, it can produce more intensity than a xenon flash lamp. Even more light intensity is available when the LED is strobed for milliseconds. Since flash lamp bulbs have a very short maximum strobe time, a high power LED light can match and outperform flash lamps using a longer strobe duration than the flash lamp. The advantage is that LEDs can generate light for the entire time an imager acquires the image.
