Abstract:
Driver concerns for LEDs used in general display lighting continue to change rapidly. Because of increased of efficacy (Lumens/Watt), LED use for lighting continues to move forward. LED lighting has its own vocabulary and set of issues that need to be understood by the design engineer. Starting with the important features of general display lighting, the current methods and practices employed to provide power are examined. LED manufacturers also assist with suggestions for improved light quality. A full study can be made of control techniques for various types and topologies of lighting systems with the advantages and disadvantages of various solutions highlighted.
