Lighting products based on light-emitting diodes (LEDs) are gaining a stronger foothold in many different application areas—consumer, commercial, industrial, and even military products. LEDs provide illumination in everything from automotive headlights to outdoor systems. Key to the design of these LED-based products is proper thermal management: LEDs that run too hot can suffer reduced operating efficiency and dramatically shortened operating lifetimes. Therefore, thermal design becomes critical to maintaining LED p-n junction temperatures that fall within the recommended limits for those devices...
