LED high-power injection molding modules are generally about 2 watts, very bright, and are generally used for side-lighting light boxes. Using this module saves the cost of light sources, the lighting effect is good, and the picture has no light spots and is very uniform. The reason is its special What material are the lenses of the high-power injection molding module made of, and what characteristics do they have?
1. Silicone lens of LED high-power injection molding module
a. Because silica gel has high temperature resistance (and can also be reflowed), it is often used to directly package LED light-emitting devices.
b. Generally, silicone lenses are small in size, 3-10mm in diameter.
2. PMMA lens for LED high power injection molding module
a. Optical grade PMMA (polymethyl methacrylate, commonly known as: acrylic).
b. Plastic materials, advantages: high production efficiency (can be completed by injection molding and extrusion); high light transmittance (about 93% when the thickness is 3mm); disadvantages: the temperature cannot exceed 80° (the thermal deformation temperature is 92 degrees) ).
3. PC lens for LED high-power injection molding module
a. Optical grade Polycarbonate (referred to as PC) polycarbonate.
b. Plastic materials, advantages: high production efficiency (can be completed by injection molding and extrusion); slightly lower light transmittance (about 89% when the thickness is 3mm); disadvantages: the temperature cannot exceed 110° (the heat distortion temperature is 135 Spend).
