The future of wireless bonded LED technology
The applications that will benefit the most from wireless bonded LED technology are ones that specifically require superior heat dissipation, enhanced durability and superior light performance.
These applications include:
• High-power or high-brightness applications such as general lighting, white goods, and automotive that require superior heat dissipation.
• Performance-sensitive applications such as plastic sorting, security applications, precision medical applications and agricultural process that require enhanced durability and consistent performance.
• Visually sensitive applications such as grain sorting, industrial measurements and small space lighting that require bright, evenly distributed, shadowless light.

As LED technology, particularly high-power LED technology, continues to evolve and become more widely adopted, wireless bonded LED technology provides key benefits to design engineers challenged with providing greater brightness, superior heat dissipation and enhanced durability with increasingly smaller footprints.

Now it is picking up momentum even though it is a decade old technology.The advantages mentioned here are really expected from a good LED.Provided that it will not increase the price of the LED.

Several drawbacks of this article:
1. Misnomer of calling flipchip as wireless! The latter term is deeply entrenched in mobile communications as is the former term in the chip interconnect industry!! You need to call a spade a spade...
2. Preaching to the choir! Most readers of EE Times are already familiar to flip chip which has been around for decades now. What I would have liked to see is a cross-section of an actual device and not cartoons.
3. Better, quantified data to backup claims made -the authors makes comments about LED arrays but does not show any data to backup. Irrespective of the interconnect method, thermal cross talk between LEDs joined at the substrate is always going to be a problem and I don't see this proven by data.
