Mini and High Power LED lighting

As display and lighting technologies evolve, so do the demands placed on their core materials. In mini LED LCD displays, conventional large-grain phosphors limit how much LED size can shrink. 

At the same time, high power solid-state lighting pushes phosphors to withstand extreme thermal and optical stress. With rising blue chip power densities, managing heat and maintaining color uniformity have become critical challenges. At Seaborough, we develop advanced phosphor powders and ceramics with high thermal dissipation and tunable scattering properties to meet these requirements. Our Crystalight® solution enables next-generation displays and lighting systems to perform with precision, efficiency, and durability.

Crystalight® Mini is a (Lu,Y)AG:Ce nanocrystalline powder with a d50 that can go as small as sub-20 nanometers, while maintaining a narrow size distribution.

Key benefits of Crystalight® Mini:

• High performance.
• High stability.
• Sizes as small as sub-20 nanometers.
• Tunable composition.

Crystalight® High Power & Ceramics, a nano-garnet based ceramic composite, based on Seaborough’s proprietary technology.

Key benefits of Crystalight® High Power & Ceramics:

• Better thermal conduction than existing solutions in the market.
• New possibilities to shape the ceramics without cutting or sawing.

As devices transition to mini LED and micro LED, the industry needs down converting materials that perform at nano to submicron scales. Nanophosphors such as YAG:Ce are strong candidates, yet conventional nanocrystalline YAG has struggled with clustered particles, low absorption and quantum efficiency, and reliability concerns.

At Seaborough we address this with an annealing approach that uses post synthetic treatments, including baking the nanocrystals at temperatures above 1000 °C. The result is high quality YAG:Ce nanophosphors with tunable particle sizes below 20 nanometers, near unity quantum yields, and no clustering. Through Crystalight®, these properties open up new possibilities in advanced lighting and in mini LED and micro LED applications such as backlight displays for tablets and monitors, wearables and augmented reality, as well as high power LED systems for outdoor and automotive use.
