Samsung Debuts Flip-Chip Packaged LEDs with Range of Operating Currents

Samsung Electronics Co., Ltd. of Seoul, South Korea has introduced the LM301A, a flip-chip-based mid-power packaged LED. The company says that the LM301A flip-chip can operate at anywhere from 0.2 watts to 1 watt. The broader range of current options gives it greater flexibility. The company’s flip-chip technology enables the lower and wider current options.

The packaged LED comes in a 3.0mm by 3.0mm form factor that is increasingly popular in LED lighting applications. The technology eliminates the need for metal wire bonding and allows the LED chip to have the shortest distance from the junction to the base of a package. The company says that these design improvements enable much lower heat resistance compared to conventional epi-up chip technology. They offer a temperature drop of about five percent per watt within a more desirable 25°C to 85°C temperature range.

“Designed with advanced flip-chip technology, the new LM301A overcomes what had been significant performance and power limitations of conventional mid-power lighting LED packages,” said Dr. Jacob Tarn, executive vice president, LED Lighting Business Team, Samsung Electronics. “We will continue to strengthen our technology leadership in the market by launching highly competitive, next-generation LED products based on Samsung’s most innovative, market-proven LED technologies.”

The packaged LED series ranges from 120lm/W efficacy at 350mA in warm white 3000K CCT, at CRIof 80+ to 170 lm/W efficacy at 65 mA, 5000K CCT, and CRI of 80+. 

The LM301A packaged LED is well suited for lighting applications ranging from ambient to high-intensity lighting, such as outdoor and high bay lighting. The company says that the LEDs are also very cost-competitive.

Samsung points out that the LM301A uses Epoxy Mold Compound (EMC) packaging, making it more reliable and extends its lifespan. Samsung claims that its EMC packaging offers more protection against heat and UV rays compared to existing Polyphthalamide (PPA) and PCT materials now extensively used in LED packaging. This protection reportedly makes it suitable for high-luminance and higher wattage LED applications.

 The new package will also support CCT (Correlated Color Temperature) specifications from 2700K to 6500K. The LM301A will be available beginning in July.
