Blue LED is optimized for remote-phosphor design

The XLamp XT-E royal blue LED is optimized for use in remote-phosphor lighting and other applications with similar requirements. The use of remote-phosphor technology — in which the phosphor that determines the color of the transmitted light is applied to optics that stands apart from the LED — is proving popular for LED bulbs designed as replacements for common incandescent bulbs. The LED manufacturer is also announcing a program to license its remote-phosphor-component patents. The combination of LED and remote-phosphor components is said to enable design of high-performance, low-cost systems.

Using Direct Attach technology to achieve higher flux, lower forward voltage, and lower thermal resistance than other technologies, the LED delivers radiant flux up to 525 mW with a 350-mA input current and an 85°C junction temperature.

Further, the devices are very tightly binned to permit highly color-consistent design; they can be ordered with wavelengths from 450 to 465 nm in 2.5-nm bins. Companies interested in obtaining a license for the remote-phosphor-component patents should e-mail
