Abstract: An LED lamp system with different color temperatures and various operation modes can resolve the problems occurred in the prior arts. By switching the AC current continuously, not only the LED lamp sets can emit lights of different color temperatures, and moreover, at the same time, the light sensitive detector and moving object detection circuit serve to detect environmental light intensity and the moving objects so as to auto-control the lighting and light intensity of the LED lamp sets so as to match the requirements of environment protection and power saving As a result, intellectual light control for LED lamps is achieved. This is beneficial to the applications of LED lamps.

Abstract: A lamp control system with various control ways includes an AC power source; a wave generator; a driving circuit; a lamp set receiving power from the driving circuit to drive the lamp set; a microprocessor receiving power from the lamp set as driving power thereof and receiving, signals from the wave generator as driving signals; a switching circuit; the switching circuit being connected to the microprocessor and receiving the signals from the microprocessor for operating the lamp; the switching circuit also controlling current flowing through the lamp set and thus controlling the illumination of the lamp set; a sensing circuit connected to the microprocessor for detecting variations of environment illuminations and then transferring detecting signals to the microprocessor to cause the microprocessor to control the switching circuit to operate the lamp set; and an illumination setting by which a user can set illumination of the lamp set.
