Patent number: 11191220Abstract: A method and apparatus for a light fixture that uses current sharing across any one or more parallel LED strings within the light fixture. A processor determines the current requirements of the one or more LED strings that are needed to produce a given intensity level. The processor then apportions the current generation capability of a power supply across all active LED strings using time division multiple access (TDMA) whereby each LED string conducts its apportioned current within its allocated time slot to the mutual exclusion of the remaining active LED strings in any given time period. The light fixture utilizes LEDs with increased forward voltage interspersed with LEDs having reduced forward voltage in the same LED string. A processor utilizes shunt devices across the one or more LEDs with increased forward voltage to substantially match the cumulative forward voltage of each LED string.Type: GrantFiled: February 2, 2020Date of Patent: December 7, 2021Assignee: Illum Horticulture LLCInventors: Stephen P.

Patent number: 10028350Abstract: A method and apparatus for a horticultural light for use in a horticultural facility that uses both continuous current control and discontinuous current control to select an intensity for each LED string in the horticultural light. Continuous current control is selected when the horticultural light is operating above a threshold intensity and discontinuous current control is selected when the horticultural light is operating below the threshold intensity for enhanced dimming fidelity. A CPU detects the number of LED strings present in the horticultural light and determines the optimal operating voltage for each detected LED string based upon the detected forward voltage of each detected LED string. Based upon the optimal operating voltage determined for each LED string, the CPU additionally selects an optimized current stabilization network for each detected LED string.Type: GrantFiled: November 24, 2017Date of Patent: July 17, 2018Assignee: Illum Horticulture LLCInventors: Stephen P.
