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.
