Beschreibung
Zusammenfassung:	The invention relates to an LED lighting device and belongs to the technical field of lighting facilities. The LED lighting device comprises a set of LED light-emitting devices which are in series connection with one another and/or are arrayed on a substrate to form lighting units after series connection, and the substrate is a transparent ceramic substrate. The transparent ceramic substrate features in good heat conduction and radiation cooling performance and is pervious to light, so that the problem about heat dissipation is solved; the LED lighting device can give out light on both the front side and the reverse side, so that lighting brightness is remarkably improved while the lighting range is remarkably enlarged.
