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.

Abstract: A direct edge-lit backlighting module includes a plurality of first LEDs separated by a first interval from one anther on a substrate and emitting a light in a direction parallel to the substrate and corresponding to each first interval, and a plurality of second LEDs arranged in another direction opposite to the aforementioned direction and alternately arranged with the first LEDs and emit a light source, so as to form at least one light bar on the substrate. A light guide plate covers the LEDs for guiding emitted lights to uniformly distribute the intensity of light. The method of arranging the LEDs alternately not only can eliminate dark shadows and reduce the cavity height of the module, but also can decrease the quantity of LEDs used, which helps conserving energy and achieves environmental protection.
