LED UV Datasheets
UVA · UVB · UVC component specifications — wavelength, radiant power, viewing angle and package outlines
Ultraviolet LEDs are grouped by wavelength band, and the band determines the application. UVA emitters (315–400 nm) drive UV curing adhesives and coatings, counterfeit detection, fluorescence inspection and insect attraction systems. UVB sources (280–315 nm) serve phototherapy and specialized plant-growth responses. UVC devices (200–280 nm) deliver germicidal output for surface, air and water disinfection. This index gathers every UV series in the Queendom component range — from compact through-hole UVA lamps to ceramic 3535 UVC packages — with links to product pages and downloadable catalogs containing full electrical, optical and mechanical data.
UVA LED SMD Series
Surface-mount UVA emitters cover the mainstream 365–405 nm window used by curing and inspection equipment. Peak wavelength is selected to match the absorption of the target photoinitiator or fluorophore; 395 nm is the volume choice for general curing, while 365 nm improves depth cure in opaque adhesives.
| Series | Package | Peak Wavelength | Power Class | Typical Applications |
|---|---|---|---|---|
| 2835 UVA | 2.8 × 3.5 mm | 395 nm typ. | Mid power | Curing modules, counterfeit detectors |
| 3528 UVA | 3.5 × 2.8 mm | 395 nm typ. | Low to mid power | Inspection strips, indicators |
| 3535 UVA | 3.5 × 3.5 mm ceramic | 365–405 nm options | High power | Industrial curing, printing heads |
| 5050 UV | 5.0 × 5.0 mm | 365–405 nm options | Mid to high power | Multi-chip curing arrays |
| 7070 UVA | 7.0 × 7.0 mm | 365–405 nm options | High power | Flood curing, large-area exposure |
Wavelength tolerance, radiant flux bins and forward-voltage groups for each series are listed in the current catalog editions below. For projects that specify a narrow wavelength window, order to bin code and confirm availability with technical sales before release.
UVB & UVC Series (3535 Ceramic)
The 3535 ceramic platform carries the short-wavelength die used in germicidal and phototherapy designs. Its aluminum-nitride substrate provides the thermal path that UVC dice require to maintain output and lifetime.
| Series | Bands | Key Feature | Typical Applications |
|---|---|---|---|
| 3535 LED UVs (UVC & UVB) | 265–310 nm | Single-band germicidal die | Surface and air disinfection, sensors |
| 3535 Dual-Chip LED UV (UVC + UVA) | 265 nm + 395 nm | Two dies in one package | Combined sterilization and inspection functions |
Through-Hole UVA LEDs
Epoxy-encapsulated UVA lamps in industry-standard 3 mm, 4 mm, 5 mm, 8 mm and 10 mm packages provide economical point sources for instrumentation, currency verification and fluorescence excitation. Detailed parameters for each lamp size are indexed on the dedicated through-hole UVA datasheet page.
| Lamp Size | Peak Wavelength | Viewing Angle | Typical Applications |
|---|---|---|---|
| 3 mm / 4 mm UVA | 395–405 nm | Narrow to wide options | Compact detectors, instrumentation |
| 5 mm UVA | 395–405 nm | Narrow to wide options | Counterfeit verification pens |
| 8 mm / 10 mm UVA | 395–405 nm | Wide | Inspection lamps, fluorescence viewers |
