Advances in High-Power Laser Diode Packaging
... In most thermal management problems, removing the heat flux generated from the heat source (in this case, laser diode) to the heat sink by means of conduction alone is insufficient. To maintain its high efficiency and long lifetime, the operating temperature of the laser diode package is kept as low ...

Solder-Point Temperature Measurement of Cree XLamp LEDs
... LEDs produce light when a current is passed across the junction of the chip. As efficient as LEDs currently are, a large percentage of the input power generates heat rather than light. Heat that is not dissipated will have not only an immediate negative impact on light output but also decrease the L ...
