Signal emission conditioning circuit based signal processing system for light-controlled LED

Abstract

The invention discloses a signal emission conditioning circuit based signal processing system for a light-controlled LED. The signal processing system is characterized by mainly comprising a processing chip U, a triode VT1, a diode D2, a diode D3, a low-pass filter circuit, the signal emission conditioning circuit, a signal bias correcting circuit and a signal buffering circuit, wherein the signal bias correcting circuit is connected between the FDBK pin of the processing chip U and the collector electrode of the diode VT1 in series; and the signal buffering circuit is connected between the signal emission conditioning circuit and the VOUT pin of the processing chip U in series. By adoption of the signal processing system, the harmonics generated by the input signal due to external interference electric waves can be eliminated or restrained; in addition, the bandwidth of the output signal can be adjusted; the output signal can be consistent to the input collected signal so as to ensure the accuracy of signal processing of the signal processing system; and in addition, the accuracy of the light-controlled LED control system on the opening and closing control of the LED lamp is effectively ensured.

Description

technical field [0001] The invention relates to the field of electronics, in particular to a signal processing system for light-controlled LEDs based on a signal emission conditioning circuit. Background technique [0002] At present, due to the characteristics of low energy consumption, long service life, safety and environmental protection, LED lamps have become one of the mainstream products for people's living lighting. In life, people often use voice control or light control control system to realize the opening and closing of LED lights. The light-controlled LED control system is favored by people because it can control the opening and closing of LED lights according to the brightness of the LED light environment, and can effectively meet people's requirements for LED lights in terms of energy saving. However, the signal processing system of the existing light-controlled LED control system is susceptible to external electromagnetic wave interference and inaccurately p...
