Abstract
An LED lighting device is disclosed. The LED lighting device uses a violet LED chip as a light source for exciting quantum dots. The quantum dots excited by the light of the violet LED chip are mixed with each other to form white light. So, the LED lighting device not just has the effects of providing a high luminous efficiency and preventing the blue light from damaging human eyes only, but also provides a better color rendering ability.
