5050 UV LEDs

5050 Multi-Wavelength UV LEDs – UVC 254–275nm, UVB 310nm, UVA 365–405nm

OVERVIEW

The 5050 UV LED is a high-power surface-mount (SMD) ultraviolet emitter in a compact 5.0 mm × 5.0 mm ceramic package. This versatile platform supports multiple wavelengths across the UV spectrum — from germicidal UVC (254–275 nm) and mid-wave UVB (310 nm) to industrial UVA (365–405 nm) — enabling tailored solutions for disinfection modules, analytical instrumentation, and UV curing systems.

Table 1. Typical Optical and Electrical Characteristics (T_j = 25°C).

Note: Values measured at 350 mA,500 mA,1000 mA, and 1400 mA per model.

Note:
• UVC (254/275 nm) and UVB (310 nm) models use AlGaN chips; UVA models use InGaN.
• Radiant flux and V_F measured under pulsed DC conditions to maintain T_j = 25°C.
• Actual performance depends on thermal design in application.

FEATURES

• Differentiated optical design: UVA models feature a ceramic dome lens for uniform illumination; UVC/UVB models use flat quartz to maximize durability and UV output in high-power applications.
• Material optimized by wavelength:
  • Ceramic dome (UVA): Improves light efficiency and viewing angle.
  • Flat quartz (UVC/UVB): Ensures minimal absorption at short wavelengths and excellent thermal resistance.

• Full UV spectrum coverage: UVC (254/275 nm), UVB (310 nm), UVA (365–405 nm)
• Dual-chip technology: AlGaN for UVC/UVB, InGaN for UVA
• High radiant flux: Up to 5760 mW @1400 mA (405 nm UVA)
• Low thermal resistance ceramic package: Stable performance under high drive current
• Standard SMD 5050 footprint: Compatible with automated pick-and-place and IR reflow
• Viewing angle: 120° (2θ½)

BENEFITS

• Design flexibility: One package, multiple wavelengths for diverse applications
• Industrial reliability: Gold wire bonding, hermetic sealing options available
• Thermal stability: Minimal wavelength shift over temperature (UVA models)
• Scalable power: Operates from 350 mA to 1400 mA depending on model
• Global compliance: RoHS, REACH, and IEC 62471 photobiological safety ready

APPLICATION

• UVC (254/275 nm): Enclosed surface or air disinfection modules (not for open exposure)
• UVB (310 nm): Medical phototherapy devices*, analytical instruments, UV sensing
• UVA (365–405 nm): Industrial UV curing of inks, coatings, adhesives, and resins
• All wavelengths: Fluorescence excitation, counterfeit detection, forensic analysis

*Note: Medical device integration requires system-level certification (e.g., FDA, CE MDR).
UVA LEDs are not effective for disinfection. System design must comply with IEC 62471.

Note: The optical lens material is selected based on wavelength performance.
UVA LEDs use a ceramic dome to enhance radiant flux and beam spread,
while UVC and UVB models employ flat quartz windows to maintain spectral integrity
and enable reliable operation in high-temperature environments.
