摘要:
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 eciis 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 may additionally select an optimized current stabilization network for each detected LED string.
