Abstract: A microcontroller configured to monitor the input voltage and load conditions, and continuously adjust the switching frequencies in order to optimize the efficiency and longevity of the power supply incorporated in a device. The microcontroller utilizes a combination of GaN switching elements with their efficient high frequency switching capabilities, together with the continuous monitoring of the load conditions, allowing the intelligent microcontroller to vary the switching frequency of the power conversion blocks as needed in order to maintain the highest efficiency of conversion. The microcontroller can be utilized to control a luminaire or other device into which the controller is preferably integrated. The microcontroller can utilize one or more environmental sensors configured for sensing internal environmental conditions and/or external environmental conditions.

Abstract: A configurable LED overhead light with a selection of lenses. The lenses are selected for the pattern of light, distance and shape of the desired illumination, of a particular installation. By varying the lens shapes and surface textures, asymmetric patterns can be achieved, and non-LED fixtures can be replaced with LED fixtures that optimize the light distribution to a particular installation site.

Abstract: An LED lighting fixture with a heat sink, LED arrays on angled facets, a reflector dish, and a diffuser lens are disclosed. The LED arrays are mounted at an angle on sloped facets, and the reflector intercepts a portion of light from the LED arrays, and redirects the intercepted light downward, resulting in a focused and collumnated light beam. Very little light is allowed to be projected upward above the light fixture, and less light is dispersed to the side.
