Liquid Forging Helps LEDs Keep Cool

July 5, 2012, By Sanjeev Ramachandran

It is predicted that high-power LEDs will completely replace the conventional lighting system in homes and offices by the next decade.

However, LEDs emit heat and if the heat is allowed to build, it can cause damage to the devices causing them to dim and lose efficiency. One way to avoid such burnouts is to provide heat sinks that will give effective cooling.

Now a new manufacturing method called liquid forging, developed by A*STAR’s Singapore Institute of Manufacturing Technology (SIMTech), promises improve how these tiny devices keep cool and last longer.

Explaining the news method, a SIMTech lead researcher said that Liquid forging is a hybrid between forging and casting. The method is especially useful in manufacturing lighter components with intricate features, like heat sinks, using wrought aluminum alloys.

Liquid forging is highly scalable allowing complex parts — using composite materials such as copper and aluminum — to be created in a single step.

This would mean that heat sinks and light fixtures can be formed as one piece, thus reducing the costs significantly.

The final products would need less matching and also the resultant heat sink can be anodized, improving thermal performance by 10-15%

The liquid forging is not confined to cooling LEDs, but it has potential to compete with traditional manufacturing processes in the biomedical aerospace and automotive industries.

With products set be released in 2013, the future for this new technology looks bright and sunny.
