The LED lantern is composed of built-in LED light source and plastic shell. Although there are different kinds of light sources, the built-in light sources are basically LED (light sources are also good or bad), so the difference is mainly reflected in the plastic shell material and production process.
The main types and differences are as follows:
First, injection-moulded LED lanterns. The shell is injection moulded, but the moulding is semi-circular. The two semi-circles are joined together to form a circular lantern body. Most of the materials are acrylic. The advantages are low cost and high production efficiency, while the disadvantages are that there are gaps at the splicing points, which affect the appearance, fragile and poor light efficiency.
Second, injection and blow-moulding LED lanterns. The shell is formed by plastics injection into the tube blank in the tubular mold, and then the tube blank is heated at high temperature and placed in the lantern mold to blow moulding. The advantages are low cost and high production efficiency, while the disadvantages are that the shell is too thin, fragile, poor light efficiency and easy to fade.
Third, blow-moulded LED lanterns. The shell is blow moulded by high temperature extrusion of plastic particles. The advantages are strong and durable, not broken, good light efficiency; the disadvantages are high cost and low production efficiency.
