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.
Claims20
An LED light module comprising:
- a base having an optical axis, a plurality of light emitting diodes (LEDs) emitting light in a direction parallel to the optical axis, an outer perimeter that substantially defines the outermost periphery of the base, and at least one outer most LED mounted proximate to the outer perimeter;
- and,
- an optical accessory having an opening that permits light to pass through the opening without modification, the optical accessory configurable to operably couple to the base, wherein when the optical accessory is uncoupled from the base, the light emitting from the at least one outer most LED is directed to a first optical distribution, and wherein when the optical accessory is operably coupled to the base, the optical accessory redirects a portion of the light emitting from the at least one outer most LED from the first optical distribution to a second optical distribution such that the second optical distribution includes both unaffected light and redirected light.
