Compared with the traditional LED illuminating lamp, the semiconductor laser light source has the advantages of being high in spectral purity, high in plant absorption and utilization rate, and the spectral line width is narrow. However, even if the semiconductor laser is used as the light supplementing light source, if the working heat of the laser cannot be reasonably diffused, the efficiency and the reliability of the whole light supplementing lamp are still affected. Particularly in the industrial application environment, the power of the used laser is high, and the heat dissipation problem is still at a core.
In the present utility model, in different embodiments, the structure of the mounting box 100 may be different, and in particular, the mounting cavity in the middle of the mounting box 100 is used for mounting various devices, while the mounting box 100 is not required to be closed (but the environment in the mounting box 100 is less disturbed by the outside when the enclosure is formed), and a corrugated structure that is beneficial to heat dissipation may be formed on the outer wall of the mounting box 100.
