Abstract: Apparatus and associated methods relate to development of a LED system with high thermal dissipation power relative to the system weight by the inclusion of open regions. The open regions reduce the weight of the optical system while improving airflow. Associated optics are described to efficiently and evenly distribute the light from an LED by tailoring the optical distribution. In addition, circuitry and methods are described to allow for the LED system to operate with existing power sources such as ballast or offline AC voltage sources or both.

Abstract: Apparatus and associated methods relate to a diversion driver module that dynamically adds a diversion current to an LED current so that the summed current maintains a predetermined minimum holding current requirement of a phase-controlled dimmer supply. In an illustrative example, the diversion current may be a function of input AC line voltage and/or firing angle of the phase-controlled dimmer supply. The phase controlled device may include, for example, a triac. The triac may supply adjustable pulse-width current to dim the LED according to a phase control signal. The diversion driver module may include one or more heat dissipating components disposed in thermal communication with the lamp base. Some driver modules may be sufficiently compact and energy efficient to provide smooth dim-to-black performance while operating within acceptable temperature limits for reliable operation while contained in the base of a standard form factor lamp, such as an E12 full-glass lamp.
