Seoul Semiconductor, the nation's leading light emitting diode (LED) maker, announced on September 5 that it has launched a new Wafer Level Integrated Chip on PCB (Wicop) product, Y22, with high luminous efficiency. It is just one-quarter the size but significantly lighter than other LED products.

Wicop is a brand-new kind of product that is free from packaging process for conventional LED package manufacturing. The new product has LED chips and fluorescent substances only without other components such as lead frames and gold wires.

The Wicop Y22 has broken the stereotype that it is hard to improve light efficiency with a simple structure of chips and fluorescent substances. Based on its own LED chip manufacturing technology and fluorescent substance technology, Seoul Semiconductor has achieved luminous efficiency of 210lm/W for a single LED package. In particular, the new product has realized a higher luminous efficiency than existing high-power LED products equipped with packages. In addition, it has a 17 percent higher luminous efficiency than chip scale packages (CSPs) which are similar in appearance with Wicop, proving its high performance and technology.

Meanwhile, the share of high-powered LED products, like Wicop, in the global LED market is rapidly rising.

According to market research firm Strategies Unlimited, super high-powered LED products that had high luminous efficiency, just like Wicop, had a 20 percent share in the total LED market in 2015. The figure is expected to grow to more than 30 percent by 2020, showing the highest growth rate.
