Consequences about using LED

Due to the growth of science and technology, the lifespan of a 21st century human being becomes splendour as compared to ancient times. The contemporary innovation of modern technology is employing “LED” in our day-today life. “LED” is an abbreviation for “light emitting diode”. An LED display is a flat panel display (thin and flat video display used in laptops), which operates on emission of light emitting diodes. The invention of electric bulb is the greatest did by the homo-sapiens. As the time goes on, the usage of electric bulb ranges from lighting to navigating aircrafts. Owing to the intensification of technology, something highly adequate and also profitable came into the market i.e. LEDs. Technically it is nothing but a source of multi color lights due to the motion of electron inside a semiconductor.

Basically LED panel is the smaller part of the LED display. LED panel can be differentiated into

*Conventional panel ( an equipment which has individual mounted LEDs)

*Surface-mounted device panel (a method which produces electronic circuits in which the components like resistor, capacitor, inductor etc. are mounted onto PCBs (printed circuit board).

Operation of LEDs in human race:

Now-a-days there are many requirements of LEDs for human welfare. The important features regarding the uses of displaying devices are

*Using of LED in Electronic Message Centre, which is much more effective than normal TVs or video in case of displaying important information. The sign displaying message can be reached to every person of that locality.

*Due to rapid growth of techniques, new texts are used in diodes, sensors which are more fruitful in communication field i.e. infrared LEDs are used in televisions, remote controlled devices, DVD players, other indigenous appliances.

*In electronic communication sector, LEDs play a crucial role such as seven-segment-display (it is an electronic device which exhibits decimal numbers in an alternative manner i.e. dotted form e.g. in digital clock), also it is reliable for accessing internet named as LI-FI.

*It is also accountable for planning, controlling and recording of airlines journeying from one place to another.

*It is most commonly used in traffic signal to avoid accident of vehicles now-a-days. For stop signaling, different color codes (universal code i.e. red, orange/amber and green) are used for human comprehension.

*Lights are used more often when a vehicle moves forward; it gets automatically on during night condition & turns of when day comes.

A number of companies providing the best products appropriate for LED sign and also displaying feature so that it becomes attractive, splendid, marvelous to look at also enhances the traffic, one of them is LED super store corp. it provides unique equipments, best standardized service, many more attractive offers for sale on different auspicious occasion like new year, Christmas eve etc., cost effective hi-quality product in different colors, cabinets , also gives an assurance for 1 year on every part of products, no extra charges like shipping, around the clock service to every customer etc.

There are some important attributes regarding the importance of LED in our daily life. Let’s try to have an experience in using LED for our domestic, industrial, commercial purposes.

Citizens Urged to Take Precaution as Tropical Storm Alice Heads towards the Virtual World Whyville.com: The Consequences of Global Warming Demonstrated in the Virtual World to Encourage Kids to Learn More about This Important Issue

PASADENA, Calif. (PRWEB) June 26, 2007

    Tropical Storm Alice is intended to raise awareness of global climate issues and is associated with the opening of the new Whyville Climate Center, which is sponsored by Penguin Young Readers Group, the publisher of Al Gore’s young adult book, “An Inconvenient Truth: The Crisis of Global Warming” (Viking Children’s Books/Rodale Books $ 16.00; 208 pages; Ages 11 up). The Climate Center will serve as the focal point for the discussion and further educational activities, while significant virtual rainfall continues for at least another 12-36 hours. This will result in widespread flooding and destruction throughout Whyville, with considerable rubbish and debris littering the virtual world. Whyville’s citizens will need to join together in a massive clean up effort to restore their environment over the next several days.

The arrival of the tropical storm coincides with a new effort to educate Whyville’s citizens about global climate issues. According to a survey conducted on the site in May 2007, 77 percent of responding citizens said that they were aware of the concept of global warming. However, only 50 percent felt they could be a part of the solution.

The Climate Center’s initial activities will focus on changes in the levels of greenhouse gases in the Whyville atmosphere, especially carbon dioxide. In the center’s CO2 Lab, citizens will be able to document increases in carbon dioxide in the virtual atmosphere from the site’s creation in 1999 to today. Traveling back in time, Whyvillians will sample CO2 levels from each year and look for correlations with specific human activity. Information on historical events in Whyville, including the rate of population growth and introduction of new industries, will be obtained from the Whyville Times (the newspaper of Whyville, with articles written by kids). Citizens will also be able to propose hypotheses and debate consequences in bulletin boards within the Climate Center.

“The objective of this activity is not to prove any particular association between greenhouse gases and the climate, in general, or our first tropical storm in particular,” said Dr. James Bower, CEO of Whyville. “Instead, we want to help kids understand the complexity involved in the growing international debate on these issues and get them involved in that discussion, since we already know that they care.”

Activities in the Whyville Climate Center will also support citizen involvement in solving the problem of greenhouse gas emission. Each citizen will be assigned their own carbon footprint calculator in order to assess their individual contribution to rising CO2 levels in the virtual world. The size of their footprint will increase, or decrease, depending on the personal choices they make, such as the number of virtual accessories they produce in Whyville’s avatar factory, the number of trips taken around the world in the warp wagon, the number of times they teleport to the moon or mars, or even which types of foods they choose to eat. Whyvillians who substantially reduce their impact will be recognized with a distinctive green badge for their avatar and will even be able to trade their carbon credits to other Whyvillians for “clams,” Whyville’s virtual currency.

“We know from our surveys that Whyvillians are concerned about environmental issues, but don’t believe that they can do very much to have an impact themselves,” said Dr. Jen Sun, president of Whyville. “This activity is intended to address both the complexities of this issue, as well as provide examples of ways that our kids can get involved – not only in our virtual world but also in the real world.”

Over the coming months, this new climate education activity will continue to unfold, impacting Whyville and its citizens in parallel to developments on this important issue in the real world.
