  • LIGHTING SYSTEM BUILT-IN INTELLIGENCE
    Publication number: 20190261477
    Abstract: The present invention provides an improved lighting system with built-in intelligence and a controlling unit. The controlling unit is provided with a sensor such as occupancy sensors or photo sensors as an intelligent system. The system allows the LED lamp to dim itself in response to autonomous or external stimuli. The apparatus also includes light emitting diode array and a power harvesting means for harvesting power from the LED lamp.
    Type: Application

  • Lighting System With Built-in Intelligence
    Publication number: 20160128154
    Abstract: The present invention provides an improved lighting system, for an LED lamp, with built-in intelligence and a controlling unit. The controlling unit comprises one or more field effect transistors and a microcontroller. The microcontroller creates a pulse width modulated signal at a frequency of approximately 120 Hz-50 kHz to field effect transistors. Further, the field effect transistors are connected in series with the LED lamp so that the microcontroller modulates a switching power converter, in addition to modulating a parallel field effect transistor.
