Beschreibung
Zusammenfassung:	An LED lighting device includes a base, light-emitting chips, a circuit coating and a lamp shade, wherein the base has a hollow structure; the circuit coating is directly coated on the upper surface of the base; the light-emitting chips are directly adhered to the base, and connected with each other through the circuit coating; the lamp shade is arranged on the base and covers the light-emitting chips and the circuit coating. The inner surface of the lamp shade includes a light distribution surface and a thermally-conductive surface, wherein the thermally-conductive surface is at least located at a central region and an edge region of the inner surface. The LED lighting device employs a solid material having better thermal conductivity as the lamp shade, and simultaneously employs a hollow base and cooling holes; therefore, heat generated by the chips can be transferred outwards via the base and the lamp shade, and then taken away by air flowing through the hollow structure and the through holes, thus allowing the entire device to dissipate heat in all directions, improving the heat dissipation performance of the device.
