The invention relates to a high-power LED light fitting based on MEMS micro-cooling device radiation, comprising a PCB (5) used for installing an LED chip. The high-power LED light fitting is characterized in that one surface of the PCB (5), which is not provided with the LED chip, is connected with the bottom of a diamond basal body (3); a microfluid radiation channel (1) is arranged on the diamond basal body (3); a sealing board (2) is arranged on the microfluid radiation channel (1); and a microfluid inlet (7) and a microfluid outlet (8) which are communicated with the microfluid radiationchannel (1) is arranged on the sealing board (2). Heat emitted and conducted to the diamond basal body (3) during the use of the LED chip is taken away by the flow of microfluid on the microfluid radiation channel (1). The invention has reasonable design, compact structure, easy manufacture and good radiation effect. The heat emitted when a super-power LED works can be quickly transferred, so theradiation demand of the high-power LED light fitting can be effectively satisfied, and industrial large scale production can be realized on super-power LED street lights. Experiments prove that the radiation efficiency can be increased by more than 50%.
