AI Technical Summary

Technical Problem

In the current breeding process of black soldier fly, the cost of supplemental lighting in light-transmitting greenhouses is low, but the hatching rate of insect eggs is low. LED lights cause flickering, which affects mating and easily breeds mites. Existing supplemental lighting devices cannot effectively improve the hatching rate of insect eggs and the survival rate of larvae.

Method used

It employs a light-concentrating mechanism, an adjustment mechanism, and a detection and control mechanism. It uses optical fibers to concentrate sunlight and automatically adjust its position to provide full-spectrum natural light supplementation. It also utilizes the principle of total internal reflection of optical fibers to continuously input indoor light, reducing the growth of mites.

Benefits of technology

It achieved an egg hatching rate and larval survival rate of over 90%, reduced the number of mites, improved the efficiency and uniformity of supplemental lighting, and adapted to changes in sunlight in different seasons.
