Abstract

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%.

Description

technical field [0001] The invention relates to a high-power LED lamp, especially a design and manufacturing process of a high-power LED lamp that integrates microfluidic control technology, micro-electromechanical system, micro-heat exchange technology and LED lamp manufacturing technology. It belongs to micro-manufacturing, The technical field where surface modification technology and micro-optical technology intersect, specifically a high-power LED lamp based on MEMS micro-cooling device for heat dissipation. Background technique [0002] With the rise of gallium nitride-based third-generation semiconductors and the successful research of blue and white light-emitting diodes, semiconductor lighting has brought another leap in the history of human lighting. Compared with incandescent lamps and fluorescent lamps, LED has become one of the main development directions of a new generation of environmentally friendly lighting sources because of its small size, full solid state,...
