Lighting System With Built-in Intelligence

摘要

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.

主权项

1. An LED lamp comprising:
an array of light emitting diodes; and a microcontroller in a controlling unit receiving feedback from at least one monitoring sensor device and generating a pulse width modulating signal at a frequency of 120 Hz to 50 kHz in response to one or more field effect transistors which controls a forward voltage to the array of light emitting diodes.
