Abstract: A light emitting diode (LED) including a combination of features that enable the LED to produce a high-brightness predetermined radiation pattern. The combination of features enable the LED to function cooler and more reliably at a higher drive currents and elevated ambient temperatures, and therefore emit light of increased brightness, without overheating, and to have a particular radiation pattern. In particular, a surface mount that is capable of operating at high drive currents and high ambient temperatures is disclosed. The LED comprises a surface mount package having a metal lead frame having mass sufficient to provide low thermal resistance, at least one anode contact pad and at least one cathode contact pad. The LED also includes a reflector positioned within the package, a semiconductor die and an optional focusing dome.
