| American Bright Introduces High-Intensity 3- and 4-Watt LED Modules
To Offer Cost-Effective, | | Chino, CA - American Bright Optoelectronics has announced a
breakthrough in power LED capabilities, with its new NovaBriteTM 3-Watt LED unit packaging, offering one of the
industry's highest powered devices, capable of displaying 6500K (IF = 350mA) with an input power of 3.0 Watts (PD)
in standard colors, and a uniquely brighter white, 120-lumen unit capable of handling up to 4.0 Watts. Immediate
cost-savings can be realized with the use of this type of single lens, high-power LED as a simple, more reliable
alternative to incandescant lighting, and a contender for replacement of higher cost, higher temperature lighting
such as Metal Halide. Applications include safety lighting, crossing gate and warning lighting, taillights, light
torches, desk lamps, flashlights, and large-screen LCD backlighting, interior lighting for automotive, architectural
lighting, and other space-conscious applications. It is also considered a high-intensity light source for general
lighting needs requiring a high intensity, long-life light source, and where thermal management is a key
design/function criterion. | | Leer la noticia completa | Miércoles, 04 Enero, 2006 - 05:49 | |
| | | Vitesse Introduces Grooming Switches That Enable Lowest Cost,
Next-generation Access and Metro Equipment | | CAMARILLO, Calif. - Vitesse Semiconductor
Corp. announced two new additions to its industry-leading SONET/SDH Time Slot Interchange (TSI) grooming switch
family: the VSC9190, 50 Gbps TSI Switch, and the VSC9191, 100 Gbps TSI Switch. Both devices are targeted at
dramatically reducing power and complexity of SONET grooming applications, while simultaneously simplifying and
accelerating the system level design process. These devices reduce power requirements by more than 50% over
comparable solutions, and, by incorporating automatic protection switching and rate aggregation into a single
device, reduce board chip count by a factor of five, dramatically shrinking space requirements and lowering costs. | | Leer la noticia completa | Miércoles, 04 Enero, 2006 - 05:43 | |

| | | LEDtronics announces LED Plant Light Bars for Plant Growth. | | How do plants capture and use light? This question has been studied and researched for
decades, and researchers have long known that plants use different frequencies of light, or different colors of
light, for different purposes. Some colors of light make plants grow and bloom, while others promote compact growth,
and some aren't really used much at all. For example, the leaves of plants look green because they reflect green
light. If a plant reflects a color of light instead of absorbing it, that color isn't used to help a plant grow. | | Leer la noticia completa | Martes, 03 Enero, 2006 - 04:43 | |

| | | FULL-BRICK DC/DC CONVERTERS FEATURE 700 W CONTINUOUS RATING FOR RF
POWER AMPLIFIER APPLICATIONS | | FRAMINGHAM, Mass., - Artesyn Technologies has launched a
series of high-efficiency full-brick isolated DC-DC converters designed specifically for use with RF (radio
frequency) power amplifiers and similar telecom equipment. The new RFF series of converters comprises five 28 V
output models, offering a choice of two input voltage ranges and three output current ratings for optimal
applications flexibility. All five models feature high power output capabilities and are rated for continuous
operation across a wide temperature range, making them ideal for use with high availability equipment deployed in
demanding outdoor environments, such as cellular basestations and last mile broadband systems. The top of the range
RFF700 model is capable of delivering 25 A at 28 V (700 W), yielding a power density in excess of 127 W/in3. | | Leer la noticia completa | Martes, 03 Enero, 2006 - 04:39 | |

| International Rectifier Introduces 100V-Rated Integrated MOSFET
Solution for PoE Applications Slashing Footprint Up To 80% | | EL SEGUNDO, Calif. —
International Rectifier, IR® introduced the IRF4000, a 100V-rated device integrating four HEXFET® MOSFETs into a
single Power MLP package for Power-over-Ethernet (PoE) applications. The new device complies to the IEEE 802.3af
specification for networking and communications infrastructure systems, such as Ethernet switches, routers and hubs,
delivering up to 15W per port, replacing four individual SOT-223-packaged MOSFETs. The reduced footprint equates to
a space savings of up to 80%, or three square inches of circuit board area in a typical 48-port board. | | Leer la noticia completa | Lunes, 02 Enero, 2006 - 05:49 | |
