Abstract
The invention discloses a separate excitation type cross oscillator based computer camera light supplementary lamp. The separate excitation type cross oscillator based computer camera light supplementary lamp comprises a separate excitation type cross oscillator which is formed by a battery, a switch, a first resistor, a second resistor, a third resistor, a fourth resistor, a fifth resistor, a sixth resistor, a first triode, a second triode, a first relay, a second relay, a first diode, a second diode, a first capacitor, a second capacitor, a first light supplementary lamp, a second light supplementary lamp, a first not gate, a second not gate, a third not gate, a fourth not gate, a fifth not gate and a sixth not gate. The separate excitation type cross oscillator directly controls the first triode and the second triode, drives the first relay and the second relay to perform cross phase splitting output and circulates in a reciprocating mode and the first light supplementary lamp and the second light supplementary lamp are lightened sequentially. Compared with the prior art, the separate excitation type cross oscillator based computer camera light supplementary lamp has the advantages of being simple in structure, few in adopted electric elements and low in cost, achieving a light supplementary effect due to a design based on the separate excitation cross oscillator, having a function of automatically controlling the brightness, being convenient to use and having popularization values.
Description
technical field [0001] The invention relates to a peripheral auxiliary device for a computer, in particular to a supplementary light for a computer camera based on a separately excited crossover oscillator. 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 a computer camera supplementary light based on a separately excited crossover oscillator 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 a s...
