Seoul Semiconductor Launches Smart Lighting Acrich LED Light Engine
Device features efficiencies of up to 100 lumens per watt.
Seoul Semiconductor has released a new LED light engine with Acrich 3 technology. The device combines as LED module with Acrich MJT 5050 series LED, Acrich3 IC technology, and an innovative heat sink and secondary optics.
patterns.
Seoul Semiconductor executive vice president of lighting sales division, Jay Kim said: “The payback period for streetlights can be significantly reduced with this new Acrich light engine. By eliminating AC/ DC converters in streetlights, maintenance costs can be lowered and reliability can be improved without compromising on price, quality and energy savings to dramatically improve the lighting experience for customers. This product will enable the market to come up with the next generation of high quality, energy efficient and competitively priced LED lamps.”
Seoul Semiconductor Seoul Semiconductor is a Global LED Manufacturer and was ranked as the fourth largest manufacturer of LED packages in 2013 according to IHS Technology market research firm.
Acrich is claimed to be the first semiconductor light source that operates directly from both AC and DC power supplies. ‘Acrich MJT - Multi-Junction Technology’ is a proprietary family of high-voltage
LEDs.The Acrich light engine does not require a complex AC/DC converter and can be operated directly from the AC mains which simplifies designs, reduces component count and improves on the reliability of the luminaire.
The new 30W Acrich engine delivers a typical luminous flux of 3000 lumens at 120VAC operation at 5000K corresponding to a typical efficiency of 100 lumens per watt. When operated in a power compensation mode the Acrich3 technology can adapt to variations in the line-voltage as great as 20 percent and still deliver power-level regulation within 5 percent to ensure uniformity of the light output.
Furthermore, the new Acrich3 solution enables smart lighting control systems the Acrich3 technology can interface through a wide variety of wireless networks such as IEEE 802.15.4, WiFi, and Bluetooth to control dimming, and further optimize on energy savings. This IP67 light engine is available in various color temperatures and beam

Cree Introduces Replacement for Halogen MR16 Lamps TrueWhite LED lamps use 83 percent less energy
Cree has introduced the MR16 Series LED lamps with TrueWhite Technology, that delivers the soft, diffused light of a traditional 50W halogen MR16 lamp. According to the company, the lamps consume up to 83 percent less energy and are designed to meet ENERGY STAR qualification.
“Cree’s latest innovation is poised to replace the billions of MR16 lamps currently installed around the world by delivering an unprecedented combination of energy savings, colour quality and compatibility. The Cree MR16 Series TrueWhite LED lamp is setting a new standard for the category,” said Norbert Hiller, Cree executive vice president, lighting.
Featuring a design that delivers greater than 580 lumens in conjunction with a proprietary lens, Cree MR16 Series TrueWhite LED lamps eliminate the glare commonly associated with 50W halogen MR16 lamps to deliver a soft, diffused light with category-leading colour rendering index of 92.
