Abstract: A system that is configured for varying light spectrum provided to plants based on sensor input to optimize plant health and growth. Preferred embodiments of the inventive concepts include an infrastructure grid of mesh networked smart drivers as part of the lighting system. The smart drivers communicate with sensors, with other smart drivers on the mesh network, and with control system software that can be implemented as a mobile application or as a cloud based solution.

Abstract: A Smart ANSI Microcontroller is provided to retrofit preexisting light fixtures. The preexisting light fixtures are configured with 5 pin or 7 pin ANSI receptacles. The Smart ANSI Microcontroller is configured to accept a variety of control signals and to control the power output of the driver of the preexisting driver of the luminaire in order to control the light output of the luminaire. The Smart ANSI Microcontroller is configured with a 5 pin or 7 pin ANSI male connector that is configured for mating engagement with the 5 pin or 7 pin female ANSI connector found in typical prior art luminaires, such as street lamps. The Smart ANSI Microcontroller allows for contemporary accessory light controllers to be utilized with the preexisting luminaires. The contemporary light controllers can be configured to connect to the Smart ANSI Microcontroller via wireless and/or wired connection.

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 kit for retrofitting an existing high intensity discharge fixture so that it operates with one or more LED bulbs. The LED kit includes a bypass ballast for supplying current to an LED replacement bulb; an LED bulb, preferably set at an angle to aim the distribution of light; a heat sink for controlling the heat from the LED bulb; a dimmer unit, for adjusting the light intensity of the LED bulb; a sensor linked to the dimmer unit or controller, to adjust the intensity of the LED bulb based on a measured input; a controller configured for controlling the dimmer and for communicating to separate devices, such as a computer or other mobile device, via a router and a wireless transceiver Internet via WIFI or a cellular connection. In a preferred embodiment the kit includes one or more lenses for even distribution of light from the LED bulb.

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.
