1. As an optical-grade product, LED lamp bead lens has strict requirements on light transmittance, thermal stability, density, refractive index uniformity, refractive index stability, water absorption, turbidity, and long-term working temperature. According to the actual choice of lens material. In principle, choose optical grade PMMA, if you have special requirements, choose optical grade PC.
2. It is necessary to equip a dust-free workshop with a level of ten thousand or higher. The operators must wear anti-static clothing, finger cots, masks and other anti-static and dust-proof measures, and regularly inspect and clean the workshop.
3. It is necessary to have professional optical injection molding machines such as Toshiba, Demag, Haitian, Chen Hsong and other brands, and strictly control the injection molding process to obtain qualified products.
4. Product inspection: no bubbles, no depressions, no sink marks, no flow lines, no crescent; shape accuracy Rt<0.005 surface roughness Ra<0.0002.
5. The product should be packaged in anti-static and dust-proof PVC, and the package must be completely sealed, and the temperature and humidity should be strictly controlled for storage, and should not be stored for more than one year.
