Abstract

The invention discloses a control circuit and method based on a sound-light control energy-saving LED lamp, and the circuit comprises a lamp cap and a control module disposed on the lamp cap. The control module comprises a power module which is connected with an intelligent sensor module and an LED lamp light source. The intelligent sensor module comprises a sound and light signal collection device and a microprocessor, which are connected through an LED lamp drive circuit. The sound and light signal collection device comprises an electret microphone, a photoresistor R, a sound signal amplification conditioning circuit, and an A/D converter, wherein the electret microphone, the photoresistor R, the sound signal amplification conditioning circuit and the A/D converter are connected sequentially. The output end of the A/D converter is connected to the microprocessor. The circuit employs the intelligent sensor to carry out data collection and processing, and the microprocessor carries out the data storage and logic judgment. The microprocessor also carries out the linearization processing of the collected sound and light signals, and carries out the automatic compensation of parameters, such as temperature and static pressure. The system enables the collection sensitivity, resolution and precision of the sound and light signals to be higher, is high in response speed, is high in control precision, and is safe and reliable.

Description

technical field [0001] The patent of the present invention relates to the field of energy-saving lighting, specifically a control circuit and a control method for an acousto-optic control energy-saving LED lamp. Background technique [0002] At present, the lighting devices commonly used in public places in my country mainly include touch-type corridor lights, voice-activated lights, light-controlled lights or sound-light controlled lights. [0003] For touch-type corridor lights, users need to touch the switch with their fingers to light up, which has the disadvantages of inconvenient operation and a section of no bright area before reaching the touch switch. [0004] For sound-activated lights and light-controlled lights, the energy-saving effect is not good; for sound-light controlled lights, the sound-light control system can only control resistive loads such as incandescent lamps, and cannot control high-brightness energy-saving lamps such as LEDs. [0005] The common ...
