Abstract
A light emitting diode illumination device comprises a light-transmitting encapsulant, a transparent core, a light source plate stereoscopic structure and a power supply device. The light-transmitting encapsulant and the transparent core can be made of glass material. The light source plate stereoscopic structure is constituted by a plurality of connecting sub-light source plates. The light source plate stereoscopic structure installed in the light-transmitting encapsulant is connected to the transparent core, and is supported by the transparent core. The sub-light source plate comprises a circuit board body and light-emitting diode dies. The light-emitting diode dies can be installed on one surface of the circuit board body by surface-mount technology. The power supply device is used for supplying power to the sub-light source plates, so that a plurality of sub-light source plates may provide illumination through the light-transmitting encapsulant.
