Latest Patents

One of Haryanto Chandra's latest patents involves a process for wavelength conversion of LED light using phosphors. This process includes testing LED dies for correlated color temperature (CCT) and sorting them based on their color emission. The LEDs are then mounted on a single submount to create an array. Various thin sheets of flexible encapsulant, such as silicone, infused with different phosphors are preformed. An appropriate sheet is placed over the LED array, and upon energizing the LEDs, the resulting light is measured for CCT. If the CCT meets the required standards, the phosphor sheet is permanently laminated onto the LEDs and submount. This lamination not only protects the LEDs from contaminants and damage but also ensures a uniform CCT across all bins by selecting different phosphor sheets for each bin of LEDs.
