1. An illumination apparatus, comprising:
- an LED module having at least a first die and a second die, the first die configured to produce a first spectrum of radiation and the second die configured to produce a second spectrum of radiation;
the LED module having a primary substantially dome shaped lens with a first texturing;
a parabolic secondary reflector optic having a first opening with a first diameter and a second opening with a second diameter, the first diameter less than the second diameter;
the primary substantially dome shaped lens positioned adjacent the first opening;
the secondary reflector optic having a second texturing on at least a portion of a light receiving surface of the secondary reflector optic;
a temperature sensor adjacent to the LED module;
a power converter providing power factor correction and operating voltage to the LED module, the power converter being a switching power supply which receives input from the temperature sensor to control a first current to the first die and a second current to the second die.

Abstract
Lighting apparatus and methods employing LED light sources are described. The LED light sources are integrated with other components in the form of a luminaire or other general purpose lighting structure. Some of the lighting structures are formed as Parabolic Aluminum Reflector (PAR) luminaires, allowing them to be inserted into conventional sockets. The lighting structures display beneficial operating characteristics, such as efficient operation, high thermal dissipation, high output, and good color mixing.
