Researchers choose quartz as the glass material for UV LED sterilization lamp beads

There are various types of UV LED sterilization lamp beads that we usually choose. Do you know what materials they use to make them? Manufacturers usually choose quartz to make the glass for UV LED sterilization lamp beads. Do you know the reason behind this? Let’s take a look together.

The main reasons to use quartz glass tube to package UV LED sterilization lamp beads are:

1. High UV transmittance: Quartz glass allows UV light to pass through, especially in the UVC band. This helps UV LEDs’ light reach the environment. The packaging won’t absorb it. This enhances the sterilization effect.

2. Thermal stability: Quartz glass has excellent thermal stability. It can work stably at high temperatures without deforming. This is important for UV LEDs that run for long periods and at high intensities. It can handle the heat from the UV LED, which helps extend its lifespan.

3. Chemical stability: Quartz glass is a corrosion-resistant material. It does not react to ultraviolet light, water, or air. This ensures long-term reliability in various environments.

4. Mechanical strength: Quartz glass is very hard and impact-resistant. It protects the internal LED chips from damage.

5. High purity: Quartz glass tube is very pure, with few impurities. This reduces ultraviolet light scattering loss. It also prevents stray substances from affecting the sterilization effect of ultraviolet light.

In summary, quartz glass is the best packaging for UV LED sterilization lamp beads. It ensures effective use of ultraviolet light. It also boosts the performance and lifespan of the lamp beads. So, it is ideal for UV sterilization applications.
