Abstract

See full text

An LED lighting device with light spectrum adjustment function, which includes a light source group, a white light color temperature adjustment switch, a red/blue light ratio adjustment switch, a controller and a constant-current control circuit. The light source group includes a red LED, a blue LED, a first white LED and a second white LED. The white light color temperature adjustment switch generates a white light color temperature control signal. The red/blue light ratio adjustment switch generates a red/blue light ratio control signal. The controller receives the white light color temperature control signal and the red/blue light ratio control signal so as to generate an integrated control signal. The constant-current control circuit outputs a driving current according to the integrated control signal to control the above LEDs in order to generate a light having a target color temperature and a target light spectrum.
