LIGHTING: COMPATIBILITY
Compatibility and reliability are key factors in the design of LED lighting devices and systems
For everyday operational scenarios, LED lighting devices and systems must be compatible with power systems and electrical infrastructure, explains PHILIP KEEBLER.


DESIGN FORUM
System-level approach yields optimized LED backlight design
LEDs are quickly becoming the dominant backlight source for large displays, but design teams need to address thermal, power-management, dimming and other issues to yield an optimal design say XIAOPING JIN and ARKADIY PEKER.
