Samsung goes LED
Wide-ranging line-up of LED light sources
Samsung Electro-Mechanics (SEM) has applied proprietary technology to develop its own lineup of LEDs — the new, longer-lasting, environmentally friendly light source that is brightening up today’s world. SEM is produces LEDs for outdoor and indoor lighting, as well as sideview and topview type LEDs for mobile products. The company also plans to expand applications to accommodate changing markets and customer needs. For example, SEM has scheduled to begin production of LED automotive lights in late 2007.

“Sunnix” is the name of SEM’s high-power LED brand, and this platform covers two lineups: 1 W and 3 W. The company has applied in-house package technology to lower the thermal resistance coefficient to 8 °C/W, laying the groundwork for increasing productivity while minimizing thermal resistance and optical properties. Therefore, when large modules are made, thermal resistance is lower than that for other LEDs, allowing greater design flexibility.
The white Sunnix LED line offers diverse color temperatures from warm to cool white, with luminous intensities ranging from 60/80 1m (350 mA) to 110 1m (700 mA). The viewing angle is 120 °, and ESD protection is 5 kV and higher.
The middle-power LEDs come in package sizes between 30 × 30 mm and 52 × 52 mm, and the color range is similar to that for the Sunnix lines – white: 2000–15000 K; color: red, green, blue and amber. The white LEDs deliver up to 20 1m (60 mA), while the tunable LEDs can be designed to emit a single color – red, green or blue – or any combination of these colors. The full color and white temperature ranges are available. SEM can also customize LED sizes to suit specific customer requirements. SEM’s high-power Sunnix and middle-power LEDs have many applications besides signage and outdoor lighting. For example, they can produce diverse colors or animation effects for electronic displays, pinball machines and slot machines.
LEDs are a safe light source that do not emit harmful UV radiation. As such, they are suitable for general lighting and for illuminating shop or museum displays without causing any damage to the items on show.
SEM began making LEDs for mobile phones in 2001 and is now a leading manufacturer of sideview and topview-type LEDs for mobile device. The company’s sideview LEDs are available in packages ranging from an ultra-slim 0.3 to 0.8 mm. The 0.6 mm thick package can deliver an industry leading luminosity of 2.0 cd.
Mobile phones are taking on increasingly complex functions and mobile products of diverse types are entering the market. These trends are expanding the range of applications for sideview LEDs. Therefore, Samsung has developed backlight units with an expanded color gamut that delivers clearer colors on-screen.
