Detailed comparison of đèn LED UV lamps vs traditional mercury lamps, helping you choose the right nguồn sáng UV based on your application needs

🔍 Core Differences Comparison

Feature	đèn LED UV Lamp	Mercury Lamp (Medium/High Pressure)
Working Principle	LED chips emit UV directly	UV generated by ionizing mercury vapor
Spectrum Characteristics	Narrow band, single Bước sóng	Broad band, includes UV, visible, IR
Startup Time	Instant on, no warm-up needed	Requires 3-5 minutes warm-up
Lifespan	10,000-50,000 hours	500-3,000 hours
Energy Consumption	Low, energy efficient	High, generates significant heat
Heat generation	Low, suitable for heat-sensitive materials	High, requires cooling system
Environmental Impact	Mercury-free, eco-friendly	Contains mercury, requires special disposal
Initial Cost	Higher	Lower
Maintenance Cost	Low, long lifespan	High, frequent replacement needed

Heat-sensitive materials: Plastic, film, and other Nhiệt độ-sensitive substrates
Energy efficiency required: Long-term operation with low energy consumption
Frequent on/off cycles: Production lines with frequent start-stop operations
Specific Bước sóng needed: Precise matching to photoinitiator absorption peak
Long lifespan required: Minimize maintenance and downtime

Cost Type	đèn LED UV Lamp	Mercury Lamp	Notes
Equipment Purchase Cost	High	Low	đèn LED UV initial investment is 2-3x mercury lamp
Energy Cost	Low	High	đèn LED UV consumes 30-50% less energy
Maintenance & Replacement	Low	High	Mercury lamps need frequent tube replacement
Cooling Cost	Low	High	Mercury lamps require powerful cooling systems
Long-term Total Cost	Low	High	đèn LED UV recovers extra investment in 2-3 years
