In the field of LED lighting, a high-refractive-index phenyl-based encapsulant named IOTA LEDH 3220 is leading technological innovation. This groundbreaking product offers an unprecedented efficient solution for surface-mount device (SMD) LED applications, thanks to its exceptional refractive index and heat resistance.

The standout feature of IOTA LEDH 3220 is its high refractive index of 1.54. Compared to traditional encapsulating materials, it more effectively extracts light emitted from the LED chip, reducing optical loss and thereby enhancing overall lighting efficiency. For lighting designers pursuing Ultimate Light Effect, this represents a revolutionary breakthrough.

Beyond its high refractive index, IOTA LEDH 3220 also boasts excellent heat resistance. Under its specified curing conditions (100°C for 1 hour + 150°C for 3 hours), it maintains stable physical and chemical properties, ensuring the long-term, reliable operation of LED products in high-temperature environments. Furthermore, its Shore D hardness of 52D provides the encapsulant with sufficient structural strength to withstand external impacts.

In terms of light transmittance, IOTA LEDH 3220 also performs outstandingly, achieving a rate of 92%. This means that after encapsulation, the LED light source remains pure and bright, delivering a comfortable visual experience for users. Additionally, its good sulfur resistance ensures the long-term stability of the encapsulant even in harsh environments.

In practical applications, IOTA LEDH 3220 has been widely used in various SMD LED products. Whether in the fields of commercial lighting, residential lighting, or automotive lighting, it has gained widespread market recognition due to its superior performance advantages.
