the LEDs will never operate outside of their recommended safe operating area
The iW3610 uses advanced digital control technology to automatically detect and operate seamlessly with a leading edge or a trailing edge dimmer or if no dimmer is present. In case of an un-supported dimmer, the device shuts down and goes into a fail-safe mode. The device is compatible with existing wall dimmers available worldwide and allows parallel lamp operation for true retrofit replacement of incandescent bulbs, halogen lamps and linear fluorescent tubes.
The iW3610 operates in quasi-resonant mode and employs adaptive gate drive control and iWatt’s proprietary EZ EMI technology to achieve high efficiency and a low EMI signature. Depending on the application, efficiencies greater than 80% and power factor greater than 0.9 are easily achievable. The iW3610’s maximum operating frequency of 200kHz enables LED designers to use smaller size components to design driver boards that are small enough to fit inside existing bulb and lamp housing or inside fluorescent tubes. In addition to the standard protection features, the iW3610 also provides over-temperature protection using an external NTC resistor for robust protection. Moreover, the IC provides temperature drift control of the LED driver current to ensure that the LEDs will never operate outside of their recommended safe operating area.
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 led high bay light in residential luminaire applications and describes a built and tested off-line GreenPoint solution for an isolated 8 W constant current LED driver.

LED light extraction and printing technology
Led do Brasil will represent our LED components, from high-brightness to lighting-class led high bay light,” said Vince Feorenzo, Cree sales director. “We look forward to spreading the LED lighting revolution in Brazil, demonstrating how LED lighting can save energy, save money and help protect the planet.”
The Intematix "phosphor-paint" retail signage solution implements a carefully designed, 50,000 hour backlight grid of royal-blue LEDs that excite the sign's photoluminescent display surface. In contrast to conventional backlit signage, in which the display surface filters white light to generate a desired color, the phosphor-paint actually generates the desired colors of light over the entire display surface. The result is high-visibility and visual quality in the sign's unlit daytime state, and vivid, "eye-popping" color, similar to neon signage, when lit.
Remote phosphor solutions have previously been applied to individual LEDs and in LED light fixtures. Intematix has created an innovative solution by marrying the elements – phosphor, blue LED excitation, LED light extraction and printing technology – and scaling the solution up to the level of retail signage, all while making sure it would deliver on the long life promise. Intematix emphasized that it had strong pending patents for the innovation, covering all aspects of the technology for phosphor-based signage based on LED backlighting.

While LEDs are more environmentally friendly
While LEDs are more environmentally friendly than halogen bulbs, new technologies for heat management and efficient servicing have made them easier to install, too. LED landscape lighting offers many benefits to commercial outdoor lighting and residential outdoor lighting projects, including energy savings, superior reliability, elimination of toxic materials and unique fixture designs.
According to NEEP, manufacturers need only to submit product data once to be considered for more than twenty utility and state efficiency programs throughout the Northeast, Midwest, Northwest, California and Canada. Utility program administrators save time not having to review individual manufacturers' specifications and can be assured that qualified LED fixtures meet energy efficiency, color quality, and projected lifetime requirements.DLC analysts examine manufacturer's test reports, passing or failing applications based on performance criteria. Products which meet the minimum DLC performance criteria are then added to the DLC Qualified Products List. The list is available to all DLC Sponsors and Participants to use in their programs for promoting SSL projects.
We see great potential for led high bay light in Brazil,” said Paulo Taminato, LED do Brasil Comercio de Produtos Eletronicos Ltda. Commercial Manager. “Later in December, we are holding a seminar about designing with Cree LEDs and the response has been overwhelming. I believe we can help reduce our country’s energy consumption for lighting with the deployment of energy-efficient LEDs.”

with extendibility across multiple substrate sizes
However, customers were looking for ways mount multiple LED pods with better aesthetics. The LEDSM-3X60 and LEDSM-1X60 address this need. These are the most recent addition to our small LED light offerings, including the LEDSM30 courtesy LED light and the LEDSM30MW mini wall washer LED light. These are ultra low current lights that offer 50,000 hours of life and IP67 waterproof durability.”
We have continued to extend our leadership position in HB-LED metrology and process control with our newest PL mapping system, the RPMBlue,” commented Tom Ryan, Director of the Materials Characterization Business Unit at Nanometrics. “Our customers in Asia are adopting the high-productivity RPMBlue to support the rapidly-growing application of HB-LEDs for backlighting of notebook and LCD televisions. This latest round of RPMBlue orders comes from end-device manufacturers as well as a leading MOCVD reactor supplier. As the HB-LED process flow becomes increasingly complex, it drives the requirement for improved control of overlay and critical dimensions in the patterning process. Our IVS185 system, shipping for the first time to an led high bay light customer, is a cost-effective solution that incorporates both overlay and CD control in a single tool, with extendibility across multiple substrate sizes.
In this project, upright freezer cases were retrofitted with LED striplights combined with occupancy sensors, and compared against standard fluorescent lighting on the opposite side of the aisle. Key findings include。

it is a leader in LED technology
The CEO of Azzurro Semiconductors, Erwin Wolf said “This license and transfer agreement is a big step for the commercialization of LEDs produced on silicon substrates. Our technology will enable manufacturers to use silicon fabs to produce LEDs on 150 mm, and in future also on 200 mm silicon substrates. We are very glad to work with Osram Opto Semiconductors, since it is a leader in LED technology.”
Azzurro, which specializes in the growth of gallium nitride (GaN) on silicon substrates, has licensed and transferred its process technology for GaN-on-Si growth to Osram Opto Semiconductors. Having pioneered the growth of GaN on silicon substrates using metalorganic vapour phase epitaxy (MOVPE), Azzurro is currently providing its customers worldwide with GaN-on-Si epiwafers for LED and high-voltage applications. Azzurro says that its unique capability to grow very thick (8 micron) high-quality GaN on silicon substrates (currently 150 mm) is expected to enable cost breakthroughs for high-brightness LEDs and GaN-based high-voltage devices.
The individual LED pods contain 15 LEDs and are fully potted. Each led high bay light has a red and black lead for 12 or 24 volt power. Two different aluminum billet mount styles are available with either chrome or black anodize finish. The first mount has a flat mounting surface, while the tubular mount style has a concave base for mounting on bars, rails and other round stock. The LED light models measure approximately 5 inches long and 1 inch wide, while the single LED light is under 2 inches in length.
