Abstract: An LED circuit with color temperature adjustment comprises a first LED string, a resistor, and a second LED string. The first LED string has a first color temperature. The resistor is connected in series with the first string. The second LED string has a second color temperature. The first LED string is connected in parallel with the second LED string. The second color temperature is higher than the first color temperature. The integrated color temperature of the first LED string and the second LED string increases when the total current of the first LED string and the second LED string increases. The present disclosure not only can provide an LED circuit with color temperature adjustment, but also can provide an LED circuit which can adjust the color temperature by the combinations of the LED strings connected in parallel or series.
