LED lighting device |
| abstract |
An LED lighting device comprising an LED light source (10A) configured to emit white light having a first melanopic-photopic (M/P) ratio; an adjustment LED light source (10B) configured to emit a blue adjustment light having a peak wavelength in a range of 465 nm to 495 nm; and a drive control unit (20) configured to control currents applied respectively to the LED light source (10A) and the adjustment LED light source (10B) to generate adjusted white light having a second M/ has P ratio higher than the first M/P ratio. |
