The present invention relates to an LED illumination device comprising: an illumination installation part; multiple illumination unit assemblies including a chip-on-board (COB) LED light source, a heat-dissipating support having the LED light source supported on one side to be able to conduct heat and a power supply electrically connected to an external power source at the other side of the heat-dissipating support to transmit power to the LED light source, and installed on the illumination installation part to be able to be attached and detached selectively; and an external power connection part connected to the external power source and electrically connected to and disconnected from the power supply during the attachment and detachment of the illumination unit assemblies to and from the illumination installation part. Accordingly, provided is the LED illumination device which has a simple structure, can be maintained and repaired easily such as the expansion, replacement, repair, etc. of illumination units, and can be modified easily into illumination units with various wavelength bands according to the demand of a user. Also, provided is an LED illumination device, wherein operations such as the expansion, replacement, repair, etc. of illumination units can be conducted very easily without a burden on a worker by minimizing and optimizing a heat dissipation structure even in configuring high-power illumination units. |
