Abstract

The present invention relates to a cooling device for an LED light source using a non- conductive liquid includes an LED light source where a PCB having a plurality of LEDs mounted thereon is received in a transparent device. The cooling device for an LED device includes a heat-dissipation device communicated with the transparent device by the a liquid circulation tube based on the heat-dissipation device directly attached to the transparent device of the LED light source; a cooling fan that is provided at the central portion of the heat-dissipation device; a buffer plate that is disposed at a lower portion of the cooling fan and has a function of preventing a leakage of liquid from the heat-dissipation device; a non-conductive liquid that is filled and circulated inside the transparent device of the LED light source; and a pump that is installed on the liquid circulation tube to circulate the non-conductive liquid.
