Abstract
The present invention discloses a lighting lamp (10), is used for emitting a plurality of lights with different color temperatures, and color rendering indexes of all the lights are larger than 90. The lighting lamp (10) includes a combination (100) of light sources and a driving module (200). The combination (100) of the light sources includes four LEDs with specific wavelengths. The driving module (200) is utilized to drive the LEDs to illuminate and to control energy distribution of luminous energy for the first, second, third and fourth LEDs, thereby dynamically adjusting to show the light with 9000K, 12000K and eight color temperatures defined by the ENERGY STAR.
