BASF has introduced a yellow-light material solution for specialized industrial uses, including semiconductors, printed circuit boards (PCBs), display manufacturing, LED production, and solar energy. The technology provides a wavelength cut-off below 530nm for high-end semiconductor applications and is designed as a direct replacement for traditional yellow fluorescent lamps and filter-based LEDs while preserving strict spectral control.
The solution employs an absorption-conversion mechanism that blocks short wavelengths below 530nm and converts them into usable yellow light. This approach addresses energy waste associated with traditional yellow fluorescent lamps, which filter out short wavelengths without utilizing the energy.
According to BASF, the new technology delivers higher energy efficiency and lower power consumption compared to conventional options, resulting in a reduced carbon footprint. It supports sustainability objectives in manufacturing environments without altering performance requirements.
The lighting integrates directly into existing systems, including tubes, panels, and explosion-proof designs, and is compatible with current power and thermal setups to facilitate installation. It maintains spectral cleanliness, uniform brightness, and visual comfort.
Key performance comparisons include:
- Equivalent brightness at reduced power consumption, lowering electricity and cooling expenses.
- A potential 25% reduction in energy use when replacing traditional fluorescent lamps or filter-based LEDs.
- Lower heat transmission, contributing to improved stability and extended service life.
- Compliance with RoHS and REACH standards on restricted substances.
- Demonstrated thermal stability and reliability, with no measurable degradation after more than five years of semiconductor operations.
Typical applications encompass cleanroom lighting, lithography processes, PCB inspection, and other operations requiring controlled short-wavelength exposure.
BASF and its partners offer sampling, on-site evaluation, and technical support, including carbon footprint analysis, to support implementation.
Energy and emissions calculations are based on 24-hour daily operation for 365 days (8,760 hours per year), an electricity price of $0.30/kWh, and a CO₂ emission factor of 0.5 kg CO₂/kWh. One tree absorbs approximately 22 kg CO₂ per year. For 1,000 tubes:
- Traditional fluorescent lamp (36 W): 315,360 kWh annual energy use, 157.7 metric tons CO₂.
- Filter-based yellow LED (20 W): 175,200 kWh annual energy use, 87.6 metric tons CO₂.
- BASF light-conversion LED (10-15 W): 87,600–131,400 kWh annual energy use, 43.8–65.7 metric tons CO₂.
The product originates from BASF’s Dispersions & Resins division, which develops, produces, and markets polymer dispersions, resins, additives, and electronic materials for industries including coatings, construction, adhesives, printing and packaging, electronics, and paper.
