TO Package UV LED Series

Q: What are the thermal dissipation advantages of the UV LEDs?

A: The TO package comes with a built-in metal heat sink, which effectively reduces the operating temperature of the lamp beads. It is ideal for scenarios requiring high airtightness and stability.
Q: Is the UVC wavelength range supported? Is special protection required?

A: Yes, the UVC (220–280nm) wavelength range is supported. Direct exposure to the human body should be avoided during use, and we can provide matching protection solutions.
Q: Can the UV LEDs be used in inspection equipment on production lines?

A: Absolutely applicable. The stability and fast response speed of the TO package make it suitable for continuous-operation production line scenarios, and customized compatible interfaces are available.
Q: What is the wavelength tolerance of the UV LEDs?

A: The standard wavelength tolerance is ±5nm, and models with ±3nm tolerance can be customized for high-precision requirements.
Q: Is a waterproof version of the UV LED available?

A: IP65-rated waterproof customization is supported, making it suitable for sterilization/curing equipment used in outdoor or humid environments.
