Description

technical field [0001] The invention belongs to the technical field of semiconductor laser applications, in particular to an insulation and heat dissipation device with a series structure of single-tube semiconductor lasers. Background technique [0002] In 1967, Hungarian Mester first discovered the biological effect of weak laser acting on biological tissues. Since then, many scholars have conducted in-depth research on its mechanism and curative effect in treating diseases through animal and clinical experiments, and proposed weak laser therapy. In the 1970s, the former Soviet Union made more in-depth research on the mechanism and effects of weak laser irradiation on organisms, and developed various therapeutic instruments. At present, various weak laser irradiation treatment equipment has entered the practical stage. China, Europe, the United States, Japan and other countries have widely used weak laser treatment equipment in health care, medical treatment, beauty, etc.,...

AI Technical Summary

Problems solved by technology

[0003] In the existing weak laser irradiation equipment, such as hair-increasing instruments and skin rejuvenation and wrinkle-removing instruments, the required irradiation area is relatively large, and the light-emitting surface can reach 10×40mm. The area is small and it is difficult to meet the requirements. It is necessary to combine multiple LDs in series. In order to facilitate heat dissipation, they are often fixed on the same metal heat conduction plate, but the positive pole of the LD is also used as the heat sink of the LD. When connecting in series, the positive poles of each LD are placed together On the same metal heat conduction plate, that is, the positive electrodes of each LD are electrically connected to each other, and a short circuit occurs, which makes it difficult to realize the normal operation of the laser.
