Selected Features

Silicone materials development for LED packaging (Mar 06)
The properties of silicone materials make them ideal for new, demanding applications such as protective encapsulants and lenses for high-brightness LEDs.

Index-matching silicones enable high-brightness LED packages (Mar 06)
Silicone materials offer HB-LED designers a number of options for chip encapsulation and lenses thanks to their basic physical properties and customizable optical properties. As Bill Riegler and Rob Thomaier of NuSil Technology explain, this can help improve the efficiencies and longevity of HB-LED packages.

LED lighting modules – taking the heat out of the situation (Dec 05)
Thermal management using appropriate packaging materials is essential for high-power LED applications, explains James Stratford of Universal Science.

Micro-optics promote use of LEDs in consumer goods
Module size and power limitations impose major challenges for the design of optics for portable consumer products. Diffractive micro-optics can play an important role in meeting these needs.

Fact or Fiction – LEDs don’t produce heat
An often-quoted advantage of LEDs is that they don’t produce heat, and are cool to the touch. Fact or fiction?

Lamina's packaging technology provides alternative approach to high-power chips
As some parts of the LED industry seek to develop larger chips and drive them at higher currents, Lamina Ceramics has pursued a different route by densely packing many chips onto highly engineered substrates.

LSD expands possibilities for beam shaping and optical control
Light Shaping Diffuser (LSD) technology offers numerous possibilities for controlling and shaping the output of LED-based systems, writes Lis Eastham.

Systems design approach optimizes high-brightness LED performance
Using a system-level approach, the performance of LED packages can be optimized to maximize the amount of light captured into the required aperture. The result is high brightness, high wall-plug efficiency LED systems for surgical illumination and industrial and dental sealant curing.

Silicone delivers thermal stability to LED packaging
Until recently, HB-LED-related research concentrated on the development of light-producing chip material. Now, as very-high-volume applications such as solid-state lighting beckon, investigations into encapsulant technology have become equally important.
