San Jose, Calif. Touting more light output, higher temperature capability and surface-mount technology, Lumileds Lighting has announced the upcoming expansion
of its Luxeon high-power LED family with new emitters that offer up to 65 lumens in white at 350 mA, 185°C allowable junction temperature, and a JEDEC moisture sensitivity level of 2a.
Representing a complete redesign, the company developed the new Luxeon products to simplify the process of incorporating them into lighting assemblies and end-user products. The new devices feature a light output of 65 to 130 lumens in white, a maximum allowable junction temperature of 185°C, which is a 50°C increase and higher than any other high-power LED, according to the company. This will result in a variety of benefits including a reduction in heat sink requirements, more light at comparable ambient temperatures, and usage in higher temperature conditions. It will also allow for higher current operation and simplify designs.
The new devices will also include new alignment features and datum reference points that assist in precision assembly for automotive applications and other products where tight positioning tolerance is critical.
A JEDEC moisture sensitivity level of 2a, allows for four weeks of unsealed factory floor life prior to preconditioning, compared with a typical JEDEC Level 4 rating for other products that provide a 72-hour production window once the product is unsealed. The products will comply with the JEDEC J-STD 020c lead-free standard to satisfy environmental mandates including Europe's WEEE and RoHS directives. They will also withstand up to three reflow cycles for greater manufacturing and rework flexibility.
The new devices are scheduled for release this summer in eight colors.
