Everlight launches HIR LEDs for proximity-sensors and high-tech intelligence touch panel applications

Everlight Electronics Co Ltd of Shulin, New Taipei City (Taiwan’s largest LED assembly manufacturer) has introduced three new 850nm HIR (high-efficiency infrared) LEDs featuring high output power and narrow viewing angles, making them suitable for use in high-tech intelligence touch panel and proximity sensors.

Two of them are top-view SMD LEDs, especially suited to proximity sensor applications. The HIR89-01C has a viewing angle of 30° and achieves a very high radiant intensity 55mW/sr at 70mA. The HIR91-01C/L297, which has a 40° viewing angle, reaches an intensity of 40mW/sr at 70mA. Wide viewing angles with high output power rarely occur with most proximity sensors, says Everlight, making the HIR89 and HIR91 suitable for all proximity sensor applications such as smart-phones as well as optical touch panels.

For side-view touch applications smaller than 80-inches, the HIR83-01B (housed in a slim SMD package) features a radiant intensity of 5mW/sr at 20mA and a viewing angle of 100°(X)/40°(Y). The asymmetric viewing angle is especially suitable for touch-panel applications.
