Wireless Bonded LED Reported to Be Up to 15% Brighter than Alternative Technologies


CAROL STREAM, Ill.--Lumex has announced the global launch of its TitanBrite Wireless Bonded LED, featuring "flip chips" that are reported to be up to 15% brighter than alternative technologies in the market. In addition to the standard 3W and 6W LEDs, Lumex's TitanBrite Wireless Bonded LED is also available in 9W.

Wireless bonded LED technology, often referred to as "flip chip," offers several key performance benefits over traditional SMT (surface mount technology) LEDs, including enhanced durability, enhanced heat dissipation, and superior light performance. Applications for the TitanBrite Wireless Bonded LED include automotive (daylight, running light, dome light, foot well, and floorboard runner lighting); appliance (cabinet lighting, accent lighting, backlighting); industrial control (donut lighting, warning indicators, inspection lighting); and medical (surgical lights, examination lights, oral surgery lighting).  It also has applications in signage (channel lighting, backlighting, warning and hazard lights); construction (warning lights, light towers, traffic lights); and the military (heavy equipment, construction and transportation lights).

The enhanced shock and vibration resistance of wireless bonded LEDs, compared to traditional LEDs, stems from its more durable design. Due to the absence of a wire bond and a hard epoxy layer, the wireless bonded LEDs are said to be five times stronger and more robustly designed than standard, high power LEDs.

In addition, wireless bonded LEDs offer superior heat dissipation and are more averse to shock and vibration than traditional high power LEDs. They can withstand higher temperatures without compromising performance and have a greater surface area for heat dissipation, making them more efficient at removing heat. 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, the company says.

Lumex also reports that wireless bonded LEDs provide superior light performance when compared with traditional LED technology. Higher light output is achieved in a more 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 creation of uneven light distribution, providing 15 percent more light output, according to the company.
