High-power LED lamp beads are widely used in car headlights, flashlights, lamps, fill lights, etc. Since high-power LED lamp beads are environmentally friendly and energy-saving, what materials are used in high-power LED lamp beads? Next, CoolMotor will give you a detailed description of what materials high-power LED lamp beads are mainly made of.

1. High-power LED lamp bead silicone lens

(1) This is because silicone has high temperature resistance (can also be reflow soldered), so it is often used to be directly packaged on LED lamp bead chips.

(2) Ordinary silicone lenses are relatively small in size, with a diameter of 3-10mm.

2. High-power LED lamp beads PMMA lens

(1), Optical grade PMMA (polymethylmethacrylate, also known as: acrylic).

(2), plastic materials.

Advantages: high production efficiency (can be completed by injection molding and extrusion); high light transmittance (the transmittance is about 93% at a thickness of 3mm).

Disadvantages: The temperature generally does not exceed 80° (heat deformation temperature 92 degrees).

3. High-power LED lamp bead PC lens

(1) Optical grade material Polycarbonate (referred to as PC) polycarbonate.

(2) Plastic raw materials.

Advantages: high work efficiency (can be completed with the help of injection molding and extrusion); slightly low light transmittance (the transmittance is about 89% at a thickness of 3mm).

Disadvantages: The temperature must not exceed 110° (heat distortion temperature 135 degrees).

4. High-power LED lamp bead glass lens optical glass material has the advantages of high light transmittance (97%) and high temperature resistance;

However, most manufacturers have now begun to develop glass molding processes and use mold casting to produce glass lenses, which can produce lenses with irregular shapes and special surfaces. Therefore, the prospects of glass lenses will be broader.
