As an optical component, the lens of the LED injection molding module has extremely high production requirements, such as dustproof, anti-static, maximum long-term working temperature, etc. Only when these conditions are met, the lens of the LED injection molding module can function normally in production and work. Some functions are manifested in the following aspects.

1. As an optical-grade product, the lens of the LED injection molding module has strict requirements on light transmittance, thermal stability, density, refractive index, uniformity, refractive index, stability, water absorption, turbidity, and maximum long-term working temperature. Require. Therefore, the material of the lens must be selected according to the actual situation. In principle, choose optical grade PMMA, if you have special needs, you can choose optical grade PC.

2. The lens of the LED injection molding module must be equipped with a dust-free workshop of 10,000 or even higher level. The operators must wear anti-static and dust-proof measures such as anti-static clothing, finger cots, and masks, and regularly inspect and clean the workshop.

3. The lens of the LED injection molding module must have a professional optical injection molding machine and strictly control the injection molding process to obtain qualified products.

4. Product inspection: no bubbles, no dents, no sink marks, no flow lines, no crescents; shape accuracy Rt<0.005 Surface roughness Ra<0.0002.

5. The lens of the LED injection molding module must be packed in anti-static and dust-proof PVC, and the packaging must be completely sealed. The storage must strictly control the temperature and humidity, and it is best not to store it for more than one year.

The above is part of the information of the lens of the LED injection molding module.
