WO2025045261 - FILL LIGHT MODULE, CLEANING DEVICE, CONTROL METHOD AND RELATED DEVICE A fill light module, a cleaning device, a control method and a related device. The fill light module (100) comprises a mounting member (110), a light source (120) and an adjustment member (130). During use, the. 3KM Optoelectronics is the first fully clear infrared laser fill light in the industry, which not only perfectly achieves true full range clarity, but also achieves two major advantages (the contrast effect of the full range clear infrared laser fill light with ordinary infrared laser fill light). In the process of crop growth, light conditions have an important impact on the growth rate, yield and quality of crops [1, 2].
