Advanced Lighting Technologies introduced a new LED lamp driver solution. The LED driver is highly efficiency and highly reliable. According to ALT, their solution is essentially an AC LED Light Engine because it consists of an LED array and a tiny 8-pin or 16-pin chip. There are no other parts, except for two wires for connecting to the AC outlet. The ALT LED solution does have any bulky components like capacitors, coils or EMI filters.
Plessey has acquired CamGaN Limited, which is a University of Cambridge spin-out formed to commercialize technologies for the growth of gallium nitride (GaN) high-brightness LEDs on large-area silicon substrates. The large lattice mismatch between GaN and silicon is one of the biggest technological challenges preventing the commercialization of HB LEDs grown on large-area silicon substrates. The new GaN-on-silicon process can overcome this issue.
Conexant Systems introduced the CX2077x and CX3102x embedded audio solutions. The CX2077x USB audio integrated circuit (IC) features the functionality of an on-chip digital signal processor (DSP), tri-color LED Pulse-Width Modulator (PWM) and LED driver into a single chip package. Pricing for the CX2077x starts at $2.32 in 1K quantities. The CX3102x starts at $1.65 in 1K quantities. A complete evaluation kit with reference board and all the necessary technical documents and software is available now.
Elma Electronic, a leading designer and manufacturer of rotary components and LEDs, now offers a high-brightness (HB) version of its rugged and high-reliability light tubes. The HB LED Light Tubes from Elma are equipped with two high-efficiency dragon LEDs and a special aluminum body for thermo-management and combining design with functionality. The tubes are available in four standard lengths and in various colors (three shades of white, red, green and blue).
Laird Technologies, Inc., a global leader in the design and supply of customized performance-critical components and systems for advanced electronics and wireless products, announced the release of its enhanced Tlam[TM] SS LLD for use as a thermally conductive printed circuit board (PCB) substrate. The Tlam SS LLD is a versatile, thermally-enhanced PCB substrate system specifically designed for heat dissipation in bright and ultra-bright LED module applications. The thermally conductive PCB substrate provides 8-10 times the heat dissipation as compared to conventional FR4-based PCBs; a key ability in keeping components cool.
Light Emitting Diode (LED)-backlit Liquid Crystal Display-Televisions (LCD-TVs) will gain considerable momentum in 2010 and beyond because of the increasing commitments from various parts of the TV supply chain, consumer demand and a higher focus on green technologies, according to iSuppli Corp. iSuppli forecasts that global shipments LED-backlit LCD-TV 40-inches and larger in size will expand to 112.1 million units by 2013, rising at a whopping Compound Annual Growth Rate (CAGR) of 405 percent from a mere 34,000 units in 2008. In 2010 alone, shipments of LED-backlit LCD TVs 40-inches in size and larger will rise by a factor of nearly eight, reaching 18.8 million units, up from 2.5 million in 2009.
ON Semiconductor (Nasdaq: ONNN), a leading global supplier of high performance, energy efficient, silicon solutions for green electronics, has launched two new GreenPoint® reference designs that will speed and simplify the development of high-efficiency LED-based lighting applications. Configured in size and features for MR16 LED replacements, the first reference design describes a built and tested 3 watt (W) to 5 W LED driver solution for driving high-brightness LEDs (HB-LEDs). The second design is targeted at designers looking to achieve compliance with the ENERGY STAR® 1.1 requirements for Solid State Lighting (SSL) in residential luminaire applications and describes a built and tested off-line GreenPoint solution for an isolated 8 W constant current LED driver.
