Two of the three new HIR LEDs are top view SMD LEDs especially suited for proximity sensor applications. The HIR89-01C has a viewing angle of 30° and achieves a very high radiant intensity of 55 mW/sr at 70mA (sr = steradian, unit of solid angle). The HIR91-01C/L97 with a 40° viewing angle reaches an intensity of 40 mW/sr at 70mA. Wide viewing angles with high output power rarely occur with most proximity sensors, 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 in., Everlight’s HIR83-01B in a slim SMD package features a radiant intensity of 5 mW/sr at 20mA and a viewing angle of 100°(X)/40°(Y). The asymmetric viewing angle is especially suitable for touch panel applications.
