Abstract

The invention discloses a sound-activated LED circuit, which includes: a transformer, which includes a primary winding, a first secondary winding and a second secondary winding, and the primary winding and the first switch are connected in series to the output terminal and the ground terminal of the rectifier circuit Between; the first voltage adjustment circuit connected between the two ends of the first secondary winding, used to obtain the first DC voltage; the second voltage adjustment circuit connected between the two ends of the second secondary winding, used In order to obtain the second DC voltage; the LED branch circuit, which includes an LED, a second switch, and a detection resistor connected in series between the first DC voltage and the ground terminal, and one end of the detection electrical test provides a feedback voltage; a microcontroller, based on a microphone The collected audio signal outputs the light control signal; the LED controller receives the light control signal and the feedback voltage, and outputs the control signal to the first switch and the second switch. Higher power supply efficiency is achieved by adjusting the coil turn ratio between the first secondary winding and the second secondary winding of the transformer.

Description

[0001] 【Technical Field】 [0002] The invention relates to the field of circuit design, in particular to a sound-controlled LED (Light Emitting Diode) circuit. [0003] 【Background technique】 [0004] According to market research, voice-activated LEDs are very popular and can replace ordinary household light bulbs. Common household bulbs rely on mechanical switches to control the lighting and turning off of the lights. The voice-activated LED is more convenient, for example, you don’t need to fumble for a mechanical switch in the dark, and you can directly control it through a specific sound. In addition, the voice-activated LED can also achieve the effect of changing colors and adjusting brightness, which these traditional household ordinary light bulbs cannot do. On the one hand, it is necessary to realize functions that facilitate the control of LEDs (such as shutdown, start, brightness adjustment, intermittent blinking, etc.), on the other hand, it is hoped that the power suppl...
