Abstract

The invention discloses a voice frequency voltage-controlled three-way computer camera light-compensating lamp which comprises a battery, a switch, a first resistor, a second resistor, a third resistor, a fourth resistor, a fifth resistor, a sixth resistor, a seventh resistor, a eighth resistor, a first light-emitting diode, a second light-emitting diode, a third light-emitting diode, a first thyristor, a second thyristor, a third thyristor, a first capacitor, a second capacitor, a third capacitor, a fourth capacitor, a first triode, a second triode, a sound pick-up, a potentiometer and a voice frequency integrated chip. The sound pick-up converts a picked voice signal into an electric signal and adds the electric signal to the voice frequency integrated chip. The voice frequency integrated chip conducts voltage-controlled modulation on the received electric signal. The light-emitting diodes generate corresponding brightness changes along with the size of the outside sound. Compared with the prior art, the voice frequency voltage-controlled three-way computer camera light-compensating lamp has the advantages that the circuit structure is simple, the adopted electronic elements are less, and the cost is low, in particular, the lamp is based on the voice frequency voltage-controlled type design, the light compensating effect can be achieved, the automatic brightness control function is achieved, and the lamp is convenient to use and has the popularization value.

Description

technical field [0001] The invention relates to a computer peripheral auxiliary equipment, in particular to an audio voltage-controlled three-way computer camera supplementary light. Background technique [0002] Computer camera is a very common computer input device, and the image of this device is blurred under the condition of very dark light, so it adopts supplementary light technology, while the circuit structure of computer camera supplementary light in the prior art is complicated, adopts electronic Many components, high cost, difficult to popularize. Contents of the invention [0003] The object of the present invention is to provide an audio voltage-controlled three-way computer camera fill light in order to solve the above problems. [0004] The present invention achieves the above object through the following technical solutions: [0005] The present invention includes a battery, a switch, a first resistor to an eighth resistor, a first light emitting diode to...
