| Summary: | 碩士 === 崑山科技大學 === 機械工程研究所 === 107 === In this research, a 0.5W48PCS LED lighting engine is used on the high-power LED charging work light thermal analysis. A LED MCPCB attached on the extrude-aluminum-fin is experimental test in the laboratory. Base on its heat transfer surface areas to design an aluminum die-casting module to improve the high-power LED charging work light thermal dissipation mechanism. Therefore, the number of subcontracts and repeated experimental verifications can be reduced and shorten the development cycle. A commercial software is applied to simulate and analyze the thermal characteristics of the working light. In order to search solutions to limit the risk of product mold development failure.
The results are indicated heat transfer surface areas of the aluminum die-casting module is 1.6 times of the extrude-aluminum -fin. In ambient temperature conditions, compared with LED aluminum-extruded-fin and aluminum die-cast module lamps, structure integrated thermal dissipation mechanism is effectively descend the lamp temperature of about 18C. In the latter case, the average temperature difference between actual measurement and numerical simulation is approximately 2C
