The invention discloses a sound and light control energy saving lamp, which comprises an MIC (microwave integrated circuit) audio input part, an audio magnifying circuit, a voltage-multiplying rectifying circuit, a direct current voltage stabilizing circuit, a photoconductive resistor, a direct current magnifying circuit and a delay control circuit, wherein audio signals collected by the MIC audio input part sequentially pass through the audio magnifying circuit and the voltage-multiplying rectifying circuit and are converted into electric signals to be input into the direct current voltage stabilizing circuit, the output end of the direct current voltage stabilizing circuit is connected with the input end of the direct current magnifying circuit through the photoconductive resistor, the output end of the direct current magnifying circuit is connected with the input end of the delay control circuit, and the output end of the delay control circuit is connected with a lamp bulb. A power supply is divided into two paths after being connected into the sound and light control energy saving lamp, one path is input to the delay control circuit, and the other path is input into the direct current voltage stabilizing circuit. The sound and light control energy saving lamp disclosed by the invention has the advantages that the self electricity consumption is smaller than 0.5 W, and the sound and light control energy saving lamp belongs to a contactless switch element, so the service life is long.
