Compatibility and reliability are key factors in the design of LED lighting devices and systems (MAGAZINE)
For everyday operational scenarios, LED lighting devices and systems must be compatible with power systems and electrical infrastructure, explains Philip Keebler.
Ironically, designers are also gaining much experience in utilizing light-generating semiconductor diodes—LEDs—to design LED light engines, or arrays of LEDs. Intelligent converters, called electronic drivers, are used to power and control LED arrays ranging from a few tens of LEDs to as many as several hundred LEDs. The dynamics of designing a set of electronics to drive a light source has gone far beyond discharge tubes filled with gas mixtures at various pressures. With LED lighting devices and systems, the LED light sources are part of the electronics package.
