Specifications:

• Peak Wavelength: 380 - 385nm (Deep UVA)
• Power Rating: 30 Watts (Industrial Grade)
• Forward Voltage (Vf): 30.0V - 34.0V DC
• Forward Current (If): 900mA - 1050mA
• Radiant Power: Extreme High-Density Output
  
• Viewing Angle: 120 - 140 Degrees
• Chip Structure: 30-Die Matrix (10 Series / 3 Parallel)
• Operating Temperature: -20°C to +60°C (Requires Active Cooling)

Key Applications & Projects

• Commercial Resin Curing: Rapid setting of UV adhesives, potting compounds, and 3D printing resins in production environments.
• Non-Destructive Testing (NDT): High-intensity illumination for magnetic particle inspection and dye penetrant testing.
• Sterilization Research: UVA-based bacterial inhibition studies (Note: Not UVC, but effective for specific biological stress).
• Mineralogy & Geology: Illuminating large cabinet displays of fluorescent minerals.
• PCB Fabrication: Fast exposure of dry film photoresist for manufacturing circuit boards.

Project Evolution 

• Past Projects (Prerequisites): If you have used 10W or 20W arrays and found them lacking the "throw" to cure deep layers or illuminate distant objects, this is the solution.
• Feature Upgrade: The 30W emitter provides the raw power needed to reduce cycle times from minutes to seconds, acting as a true industrial workstation upgrade.
• Effort Level: Expert. Requires advanced knowledge of thermal thermodynamics and high-voltage constant current driving.

Virtual Technician & Wiring

• DANGER: EXTREME UV INTENSITY. This device emits hazardous levels of UVA radiation. NEVER look directly at the source. UV-rated safety goggles and protective skin covering are mandatory during operation.

• Thermal Management: CRITICAL: A passive heatsink is NOT enough. You MUST use a large aluminum heatsink combined with a high-RPM cooling fan (Active Cooling). Failure to cool will destroy the chip in < 2 seconds.

• Driving: Probots™ Logic-Safe ⚡ Rule: Use a dedicated 30W Constant Current Driver (1050mA). Do not attempt to drive this with a simple resistor or voltage regulator.

Wiring:

• Positive (+): Indicated by the + sign or wider solder pad.
• Negative (-): Indicated by the - sign or narrower solder pad.

Frequently Asked Questions (FAQ)

1. What is the actual power consumption?
   It draws approximately 30 Watts at full load (approx. 32V @ 950mA).

2. Can I use a 24V power supply?
   No, the forward voltage is 30-34V. You need a Boost Driver to step up the voltage.

3. Is 380nm better than 395nm for curing?
   Yes, 380nm provides higher photon energy, penetrating deeper and curing difficult resins faster.

4. How fast will it overheat without a fan?
   Instantly. The temperature will exceed 150°C in roughly 1-2 seconds without a heatsink.

5. Can I use a computer CPU cooler?
   Yes, an old Intel/AMD CPU cooler with a fan is an excellent, cost-effective cooling solution.

6. Is it waterproof?
   No, the COB surface is sensitive to moisture and must be protected.

7. Does it emit visible light?
   Yes, a dim purple glow, but 95% of the energy is invisible UVA. Do not judge brightness by eye.

8. Can I dim this LED?
   Yes, if your Constant Current Driver supports PWM or Analog dimming.

9. What is the lifespan?
   50,000 hours, provided the junction temperature stays below 65°C.

10. Is it safe for home use?
    Only if enclosed in a light-proof box. It is too bright and dangerous for open-air home lighting.

11. Will it fade fabrics?
    Yes, high-intensity UVA will bleach colors and degrade plastics over time.

12. Can I solder wires directly?
    Yes, but work quickly. The copper base draws heat away from the soldering iron very fast.

13. Why does it have a copper base?
    Copper is required to move the massive 30W heat load away from the dies efficiently.

14. Is it compatible with 3D printers?
    It is often too powerful for standard LCD screens but excellent for post-curing chambers.

15. Does it come with thermal paste?
    No, high-quality thermal paste must be purchased separately.

16. What is the current rating?
    We recommend running it at 900mA-1000mA to extend lifespan, though max is 1050mA.

17. Can I run it on 12V?
    No, you must use a Step-Up (Boost) driver module.

18. Is it Probots™ Secure-Transit  protected?
    Yes, packed in anti-static, shock-proof rigid packaging.

19. How many dies are inside?
    It uses a 30-die matrix (10 Series, 3 Parallel) of 1W chips.

20. Can I look at it with sunglasses?
    No. Standard sunglasses are insufficient. Use ANSI Z87.1 rated UV safety glasses.
