16.12.2011 - Seoul Semiconductor Launches ZC, a Chip-On-Board Type DC LED
Reduces thermal resistance to boost life expectancy and enhances design convenience and price competitiveness for manufacturers

December 7, 2011, Seoul – Seoul Semiconductor (www.seoulsemicon.com), a Korean LED packaging company launched its Chip-On-Board (COB) Type of Direct Current (DC) LED, named ZC (Z-Power COB). ZC series, developed based on Seoul Semiconductor’s Z-Power LEDs which are mainly used as a light source of high-brightness and high-power, decreases thermal resistance, resulting in an exponential improvement in LED lighting product life expectancy. Moreover, it allows manufacturers to conveniently install and design price competitive products.

The ZC Series is designed as a COB type and removes the need for the LED to be surface-mounted on to a metal plate, allowing manufacturers to bypass the chip connection process before use. Companies can trim manufacturing and management costs and greatly improve end product price competitiveness.

Furthermore the use of highly-reflective aluminum substrates in ZC also greatly improves the brightness and significantly prolongs LED bulb life spans. It is possible to use a single ZC from the ZC series to develop a LED light bulb which then allows light to be distributed more evenly than lights that connect several LED packages to a single module.

ZC will be offered in 6W, 10W and 16W, each of which will be appropriate replacements for 40W, 60W incandescent light bulbs and 100W down lights, respectively.

“The ZC will enable manufacturers to easily produce various LED light designs and providing longer-lasting LED lights,” explained Sunghoon Bae, Vice President of Seoul Semiconductor. “As with the recent release of our AC LED, Acrich 2, the launch of our DC LED, ZC, is aligned with Seoul Semiconductor’s commitment to providing a diverse and innovative product portfolio for consumers alongside continued investment in research and development”

The recently launched ZC Series will begin mass production in December and will subsequently be available to customers.

 26.8.2009 - Acriche Family Exceeds DC LED efficiency
Announcing a new Acriche device, the A4–AC LED with better luminous efficiency than DC LED
Luminous efficiency of 75lm/W, Color Rendering Index (CRI) greater than 85

Seoul Semiconductor Inc. (CEO Chung Hoon Lee, www.acriche.com), a world-leading LED manufacturer held a press conference in Korea, the US and China on August 26th to celebrate a new product, the Acriche A4 with world’s best luminous efficiency of 75lm/W, and introduced the A4 to the mass market.

Two-third’s of the world’s lighting consists of warm white lights (2700K to 3000K); the newly announced product is to be mass produced and readily available this quarter, capable of replacing warm white incandescent and CFL light sources in many applications.

Currently, white LED’s are divided into two major markets: products with a High Color Rendering Index (CRI) greater than 85, which is close to natural light, and products with a Normal CRI of 70 to 80. High CRI products will often be significantly less bright than their lower CRI counterparts, but due to their similarity to natural light High CRI sources are excellent for high quality light applications. LED’s with normal CRI focus more on brightness than on color and have the disadvantage of being different from natural light. Consequently, a compromise was required between brightness and CRI.

The new and highly innovative Acriche A4 product has technology that is able to satisfy both CRI and brightness. The past requirement of lowering luminous efficiency by several tens of percent is overcome by the A4. The A4 devices have a color temperature of 3000K and include multiple new technologies provide excellent efficiency of 75 lumens per watt (lm/W) with a High CRI of 85.

Alternating Current (AC) LED’s with better luminous efficiency than LED’s with Direct Current (DC) for the first time is very significant. Seoul Semiconductor stated that “with the mass production of the Acriche A4 series, we will be able to provide both high quality and normal use markets with light sources that have exceptional performance and lower prices. With the A4 series, we want to spread the name “Acriche” far and wide as the world’s best LED brand”.

Significant advantages of the Acriche A4 series include:
▲It is possible to use Acriche products on AC power freely between 100V and 230V without additional conversion. Only a simple, inexpensive diode bridge is required.
▲Different than other Acriche products (such as the popular A2 and A3 series), the A4 uses 50Vrms per package and 110V-220V can be achieved by connecting multiple devices in whatever manner is needed.
▲Whether used in light bulbs or light structures with arrays of LED’s, the best suitable design is guaranteed due to the degree of freedom of placement and configuration of the A4

* CRI (Color Rendering Index):
Color Rendering Index (Ra) indicates how much a light resembles a natural light source with the influence of the light on various colors of objects. It is measured in units from 0 to 100, where 100 indicates the most similar to natural light.
