Optics-Electric-Thermal Integrated Module
KWCOB integrates optics, electronics and thermal management into a single module, achieving high power density with efficient heat dissipation and stable light output. This technology won the Best Product Design Award at the 11th Alighting Awards.
Key Advantages
- Fully integrated optical-electrical-thermal design that minimizes interface thermal resistance
- Supports continuous stable operation at kilowatt-level power
- Modular structure for rapid matching with airport high-mast and terminal downlights
- Validated through long-term aging tests supporting a 10-Year Lighting Program
Transparent New Ceramics Phosphor
KWCOB’s independently developed transparent fluorescent ceramic phosphor features outstanding thermal quenching resistance and high-temperature stability. Even above 200°C, it maintains high luminous efficacy and low light decay — the key material foundation for long-life kilowatt-level COB.

1000W-class COB Packaging Technology
KWCOB overcomes the limitations of conventional COB packaging with high-power-density, low-thermal-resistance technology and an innovative independent phosphor-conversion heat-extraction channel. This design effectively reduces junction temperature and enhances long-term reliability. The technology is fully protected by independent intellectual property.
Key Advantages
- High power density enabling single-source kilowatt-level output
- Independent phosphor-conversion heat-extraction channel that significantly lowers thermal resistance
- Fully independent IP, avoiding risks of public-mold homogenization
- Complete power range from 2W to 2000W, covering all airport scenarios from airfield guidance to apron lighting

Deep Anti-Glare:UGR < 19, controlled across the whole ceiling. A single Ø33 mm light-emitting surface gives one optical path to manage — deep anti-glare without giving up output, in terminal halls and public spaces.
Full Cutoff:ULOR = 0, zero uplight. No glare to the control tower, no sky glow, no interference with approach-light signals — dark-sky-friendly and ICAO-compliant for aprons and landside.
Above 100 W, nobody publishes long-term data. We do.
