Wireless bonded LED touts very bright output
Lumex announced the global launch of its TitanBrite Wireless Bonded LED featuring “flip chips” that are said to be up to 15 percent brighter than any others in the market. In addition to the standard 3-W and W LEDs, this LED is also available in 9 W. High light output is achieved in a compact space, and the light performance is not disrupted by shadows or other obstacles to consistent performance. With wireless bonded technology the chip can directly emit light from the top and the side with no wire bond casting shadows or creating uneven light distribution. The enhanced shock and vibration resistance of wireless bonded LEDs stems from its durable design. Due to the absence of a wire bond and a hard epoxy layer, the wireless bonded LEDs are asserted to be five times stronger and more robustly designed than standard, high power LEDs. They can withstand high temperatures without compromising performance and have a large surface area for heat dissipation. Due to the placement of junction pads on the bottom of the flip chip, heat can be transported faster than with a regular high power LED, keeping this technology 25 percent cooler than traditional high power wire bond technologies, according to the company.
