Led Tube light source driver IC needs

The current DC Led Tube light source is a low voltage (VF = 2 3.6V), high current (IF = 200 1500mA) semiconductor devices work, you must provide a constant DC current to the appropriate normal light. Direct current (DC)-driven DC Led Tube light source technology has become more mature, because we use everyday lighting is high-voltage AC power supply (AC100-220V), so the technology must be used to obtain lower step-down voltage, common is a switching power supply step-down, and then alternating current (AC) converted into direct current (DC), then the driver IC can be converted into DC current source to promote Led Tube light shine. Therefore, the DC drive Led Tube light source system application program must be: switching power supply + constant current source. Led Tube must have a certain amount of space inside to accommodate the power supply module, but the E27 standard screw is very limited space, it is difficult placement. Whether through the step-down switching power supply, or other methods, the system will have a certain amount of wear and tear, DC Led Tube in AC, DC conversion between about 8 to 25% of the electricity is loss of efficiency of the system difficult to achieve over 90%. Thereby increasing the power conversion efficiency has been the chip and power supply manufacturers to pursue.

Advances In Microscope Technology Means Clearer Results

blogger

Microscopes have come an unbelievably long way since they were first developed in the late 16th century. While Antonie van Leeuwenhoek is often credited with being the creator of the first microscope, it was actually one of two optics pioneers who is the real father of the instrument: Zacharias Jansen or Hans Lippershey. Of the three, it is Lippershey who is most widely considered to be its inventor, an idea which is especially credible given that he was also the designer of the first modern-style telescope. Leeuwenhoek would not be born for nearly half a century after the earliest models were first built.

The microscopes of van Leeuwenhoek’s invention provided at best 275 x magnification. For its time it was truly impressive and broke new ground, enabling a host of scientific discoveries and advancing scientific knowledge and medicine in almost every way imaginable. Today of course, even many inexpensive of microscopes are capable of much higher levels of magnification and a variety of new microscopy technologies are available to allow scientists, physicians and researchers to get a close up look at the invisible world around us.

Optics have increased in sophistication by orders of magnitude in the last four centuries, with the lenses being used in microscopes being immeasurably improved and more powerful with every passing year. It’s not only in the design of the lenses used that microscopy has advanced – there are an array of new technologies behind the magnification power of the modern laboratory microscope.

Over the long history of these instruments, we have seen them advance to having a single objective to multiple objectives, the addition of adjustable viewing stages, improved focus mechanisms and the development of the stereomicroscope (actually two microscopes which focus on a single point rather than being one microscope with two lenses).

Microscope illumination has advanced by leaps and bounds along the way. From the earliest days of microscopy when illumination would have meant sunlight or perhaps candles, we have progressed to an age where we have not just high power microscope lenses with magnification power of up to 1000x, but illumination to light the slide from below (known as bright field microscopy) and illumination technologies which exclude scattered light to allow the observer a view of the specimen on the slide and nothing else (a method called dark field microscopy which is also used in non-optical microscopy).

Not only have optical microscopes made progress which would be unimaginable to Hans Lippershey, but there are now microscopy technologies which do not rely on optics and provide us with an incredibly powerful tool for looking deep within the natural world. Electron microscopy has been able to show us the microscopic world in greater detail and at magnifications which go beyond anything van Leeuwenhoek would have dreamed; as high as 1,000,000,000x by using a carefully directed electron particle beam to produce high resolution images.

From the lenses used in modern high power microscopes to stereomicroscopy, advances in microscope illumination and electron microscopy and other non-optical instruments, the history of the microscope has been one stunning advance after another. With each improvement comes new insight and revelations about the world around us. In an uncertain world, one thing that can be counted on is that these instruments will continue to progress and amaze us with the discoveries they facilitate.

Audi Headlight Technology

blogger

The new Audi A6 intends to challenge a lot of technology found in its competitor models, one of these innovations is the new all LED headlights. The A6 will be the first executive saloon in the market to have all LED headlights, an optional extra in exchange for the more familiar halogen or bi-xenon lamps that come as standard.

The Audi A6s advanced LED headlight units emit a strong white light that is similar to daylight, and use just 40 watts of electricity each, making them yet another important weapon in the battle against energy consumption. The advanced LED units use just four one-chip and five two-chip LEDs to create dipped-beam light, and 24 white LEDs to make up the daytime running lights in each headlight. This keeps power consumption and maintenance down, and gives excellent life span.

All LED headlights are not new in the Audi line-up, the Audi R8 was the first ever production car to feature all-LED headlights and now are becoming common across the Audi range. The advanced all LED headlights will also be available on the new A7 Sportback and Audi A8 luxury saloon.

The all LED headlights are further enhanced by intelligent systems such as adaptive light control and high-beam assist, which give maximum visibility without dazzling other road users. Simply put the adaptive light system adapts the light provided by the headlights to the driving conditions, with different arrangements of light when driving in the city, country roads and on motorways.

The Audi high-beam assistant automatically varies the range and width of the headlight beam between dipped and full according to the road conditions. The system also incorporates an all-weather function that uses the rear view mirror camera to detect the lights of on-coming traffic and adjust the headlight intensity to give optimum visibility in varying conditions without disturbing other road users.

The Audi A6 is now available to order from Audi Bury St Edmunds, prices start from 30,145 for the 2.0 litre TDI model. The all LED headlight upgrade costs an additional 2,710.

AVS Technology Breaks Iron Triangle of Good Fast and Cheap

blogger

by Anthony W. Hawks, Chief Legal Officer, e-LYNXX Corporation

AVS Technology is the basic procedural component of any automated solution for buying custom goods and services that must be defined by production or performance specifications at the time of purchase. It includes the following steps:
ENTER vendor attributes
ENTER project specifications
MATCH vendor attributes to project specifications to determine sub-set of qualified vendors
SEND project specifications to sub-set of qualified vendors
RECEIVE a bid response from at least one vendor

When these steps are applied using a computer-operated system, a unique competitive bidding environment can be established where vendors of custom goods and services are now willing to offer their lowest prices to fill idle production capacity. This strategy is called “contribution pricing”. When vendors bid work (even when bidding well below normal rates), any income obtained above out-of-pocket costs “contributes” to fixed costs and overhead and, when absorbed, to their bottom lines.

Prior to AVS Technology, buyers of custom goods and services were faced with the “iron triangle” of quality, timeliness, and cost. Regardless of the industry involved, every procurement or supply chain solution seeks to attract business customers that want to achieve the purchasing trifecta of “good, fast, and cheap.” Before AVS Technology, however, a buyer could only achieve two of these three goals at any one time, not all three simultaneously.

AVS Technology breaks the “iron triangle” because it allows pre-qualified vendors with excess idle capacity to provide an extraordinary low price without risk of establishing future buyer price expectations. In other words, price is no longer tied to quality and timeliness of delivery. This is what makes AVS Technology integral to all current and future e-commerce methods and systems for buying custom goods and services including ERP systems, general supply chain management systems, specialized product or service procurement systems, and even older legacy systems. One such system for organizations with significant buying needs in direct mail, marketing, publications, packaging, labeling and other types of print is currently being offered by American Print Management. Regardless of the industry or buying need, however, all users and providers of such e-commerce methods or systems are required to license AVS Technology if they wish to benefit from this revolutionary innovation.

AVS Technology is unique in creating a controlled bidding environment in which repetitive purchasers of custom goods and services can leverage the open production capacity of their preferred vendors in a way that virtually guarantees “contribution pricing” that is, below normal pricing that seeks primarily to absorb out-of-pocket costs and some level of fixed costs and overhead. This is accomplished by allowing qualified vendors to bid high, low, or not at all (1) without having to consider buyer pricing expectations; (2) without fear of setting either high or low precedent for future bid prices; and (3) without worrying about being denied future bid opportunities for which the vendor is qualified. Freed from these concerns, bidders offer pricing based on their open production capacity at the time each job is bid, knowing that if they bid low this week when they are hungry for work, they are not bound to offer the same low price next week when they are busy with other orders.

The technology is based on a series of patents that the U.S. Patent Office awarded to e-LYNXX Corporation, including Patent No. 6,397,197, Patent No. 7,451,106, post-Bilski Patent No. 7,788,143, and Continuing Application 12/8885,423 (collectively, the “AVS Technology”). This thicket of patents covers all custom goods and services, not just print.

Licensing AVS Technology should be viewed as both a strategic benefit and a legal requirement. Any organization with a computer-operated system that procures custom goods and services, by following the steps outlined in AVS Technology, is required to obtain a license to use (or continue using) the patented procedure protected by AVS Technology. This applies to systems that are developed internally as well as those used through third-party brokers, procurement services and system providers. Organizations should check with their system or service providers to ensure that the system being used is in compliance with AVS Technology licensing requirements.
