NO UV YELLOW LED TUBE Without suited yellow filters, artificial light as well as daylight will expose substrates coated with photoresist within seconds or minutes with a dose of several mJ/cm2 making reproducible litho-processes impossible. Today, Yellow LED tube with special UV cut material has enough brightness to illuminate the clean room and to enable reproducible litho-processes.
Approvals and markings
• Uniform lighting without glare and flicker.
• Blue light at 0.01%-0.02%.
• The yellow led tube can effectively filter out the light wavelength under 520nm.
• Designed and manufactured to replace the 18W, 36W fluorescent tube. Applications Areas:
• PCB electronic semiconductor factory.
• Archives, libraries, museums.
• Art galleries and boutique shops.
• Printing ink print on color inspection.
• Food production workshop.
