The invention discloses an LED lamp brightness and color temperature flexible control method based on a DC bus voltage signal. The method comprises the following steps: setting parameters of an LED lamp; setting real-time adjustment parameters according to the parameters; acquiring a voltage value U of the direct-current bus; and calculating a brightness set value and a color temperature set value of the LED lamp according to the voltage value U. And according to the brightness set value and the color temperature set value, adjusting the LED lamp of the light storage straight and flexible building. The invention further discloses a flexible controller. Compared with the prior art, the problem that the user comfort requirement which changes along with the change of individuals and time cannot be met when the LED illumination participates in the load flexible adjustment in the light storage direct flexible building is solved, so that the use comfort of the user and the willingness of the ...
