Abstract
The invention discloses a light adjustment and tone adjustment control circuit, which comprises a power supply circuit and a light adjustment circuit connected with the power supply circuit. An output end of the power supply circuit is connected with a first LED light source and a second LED light source. The two LED light sources are connected in series, and the tube pressure and color temperature of the first LED light source and the second LED light source are different; the invention also discloses a realization method of a light adjustment and tone adjustment control circuit. In the present invention, at least two LED light sources with different tube pressures and color temperatures are connected in series to form a whole light source, and the output current of the power supply circuit can be changed by the light adjustment circuit to realize light adjustment and tone adjustment, which has the characteristics of simple circuit design and low operating cost.
