The invention discloses a color temperature-adjustable LED light source. The LED light source comprises a heat dissipation base plate, a bracket fixedly arranged on the heat dissipation base plate and a first LED chip fixedly arranged on the inner part of the bracket, and further comprises at least one second LED chip which is in parallel connected to the first LED chip, wherein the second LED chip is further connected to an adjustable resistor in series. The color temperature of the color temperature-adjustable LED light source can be adjusted anytime anywhere, so that the LED light source is not required to be changed according to the different color temperature requirements of users on the LED lamp. 本发明公开了种色温可调的LED光源，包括散热基板，固定在散热基板上方的支架以及固定在支架内部的第LED芯片，其还包括有与所述第LED芯片并联连接的至少个第二LED芯片，所述第二LED芯片还串联连接有可调电阻。本发明的色温可调的LED光源使得LED光源的色温可以根据需求随时随地调节，从而使得LED灯具针对不同色温需求不再需要重新更换LED光源。
