UV LEDs fall into three categories: UVA, UVB, and UVC, spanning wavelengths from 200nm to 405nm. For UVA LEDs, they range from 315nm to 405nm, with 365nm and 395nm being particularly prevalent.
WELCOB is absorbed in providing UV LEDs with high brightness, high thermal conductivity, high reliability and high voltage resistance.
WELCOB HU7440-110-50W-405 COB LED leverages flip chip packaging and premium high-thermal-conductivity aluminum. This enhances heat dissipation, allowing it to operate directly on AC110-130V with instant start-up and rapid response. No external power supply is needed, and it has multi-circuit protection for reliable performance in harsh conditions. Emitting at 405nm, it suits UV-curing lamps, stage lights, UV-detection lamps, therapy lamps, nail lamps, plant-growth lamps, and landscape lights.
Features
- AC 110-130V operation eliminates the need for extra LED drivers, cutting lamp cost.
- Chip-on-board design makes it more compact and lightweight than DC lamps.
- Constructed with 2.0W high-quality aluminum and flip chips for efficient heat dissipation.
- No gold-wire packaging reduces chip internal resistance and slows aging.
- Anti-interference devices and multi-surge protection up to 4KV.
- An integrated circuit (IC) controls overvoltage and overcurrent.
- Voltage regulator filters power grid fluctuations.
- Temperature-control IC automatically adjusts wattage for stable operation.
- Stable performance with a lifespan of up to 50,000 hours.
- Solderless input terminals improve wiring efficiency and lower labor cost.
- Simple structure with waterproof, moisture-proof, corrosion-proof, and short-circuit-resistant features.
- Easy replacement reduces maintenance costs.
- Optional installation with led holders or PC lenses offers more lighting design possibilities.
