Compared with CCFL, LED as the backlight has the advantages of thin, environmental protection, energy saving, etc., but the cost is the biggest disadvantage, the proportion of the 2007 laptops with LED backlight is expected to be lower than 8%, mainly due tois that the competing demands of other applications, the high intensity led lamp must be screened, how to melt do not meet the requirements of LED backlight module would be most needed to address the issue; want lower prices in the TFT-LCD plant with the backlight module to reduce costs, while the LED manufacturers in the gross profit margin of other applications better circumstances, whether the large number of suppliers are also key.

 

11.3 inch and 12.1-inch LED-backlit laptop notebook vendors only introduced in 2006, due to the small number of 12.1 inches laptop, turn LED backlighting as a high-end models, a limited number of demand; 2007 Apple, ASUS, DELL and other computer manufacturers will continue to launch 13.3-inch and even larger 15.4-inch led high bay lighting products, but still positioned as a high-end models, there is no willingness to volume shipments. Product positioning of the computer makers for using the LED backlight module is not changed, will not be much help for the LED industry.

 

In the field of LCD TV, LED backlight module cost is too high, almost more than three times that of the same size CCFL backlight module, LED-backlit high intensity led lamp is also more than 30% of the price of the same size models. Environmental consciousness needs to be enforced.

 

 

 

1) high intensity led lamp is more than half a century old technology, it has many shortcomings explained above, is a long overdue elimination technology. It should be and incandescent lamps, halogen lamps and stage of history.

 

2) many of these chips claim has the PFC can improve the power factor, in fact, it only improves the load power factor as the high intensity led lamp, to make them look close to the pure resistance of incandescent and halogen lamps, and has not improved, including the power factor of the entire system, including the led high bay.

 

4) all of the LED dimming system are also to adjust the LED forward current, the existence of the previously described chromatographic offset shortcomings.

 

5) the installation of high intensity led lamp proportion of less than one ten thousandth, while the proportion of thyristor switches installed in the wall even one ten thousandth of the SCR dimming lamps not because the vast majority of the installation of SCR dimming are table lamps, bedside lamps, floor lamp. Moreover, There are dozens of different specifications of the SCR and transistor tone light switch, in fact the development of IC is impossible to compatible with all of the thyristor switch, but only compatible with a small part of.

 

6) high intensity led lamp is a new Genesis technology, it has incomparable superiority. There is no need to sacrifice the advantages of the LED in order to take care of the backward of other LED lighting products. Should not go to the wall of the newly installed SCR switch to LED dimming.

On the morning of September 11, 2001, 19 hijackers control of four airliners. The four aircraft were to fly from Boston, Newark and Washington, DC (Washington Dulles International Airport) to San Francisco and Los Angeles on the way. Morning 8:46, American Airlines Flight No. 11 crashed into the World Trade Center North Block, followed by the Joint Aviation 175 flight rushed 9:03 am South Block. 9:37 am, another group of hijackers control of American Airlines Flight No. 77 crashed into the Pentagon. The fourth plane – United Airlines Flight 93, the ultimate goal of the U.S. Capitol or the White House, the passengers and hijackers struggle on the plane, the plane at 10:03 AM in Pennsylvania Shanks Virgin near crash.

high intensity led lamp is one of led streetlight. high intensity led lamp call 911? I have to say, high intensity led lamp really need a better future without the help of 911.

In hijacking the process, the hijackers use of weapons stabbed or killed pilots, flight attendants and passengers. Airplane passengers to get in touch with the outside world report said the hijackers use the knife stabbed the flight attendants, and at least one passenger was stabbed including two hijackings. There are some passengers tried to use the cabin phone and mobile phone with the outside world to get in touch, and provides some details about the hijacking. These details include: each aircraft has several hijackers; hijackers use mace or other toxic chemical sprayers, such as tear gas or pepper spray; some of the crew members were stabbed. 911, the Commission has identified two hijackers in hijacking before purchased Leatherman multi-function hand tools. A flight attendant on Flight 11, a passenger on Flight 175 and the number of passengers on Flight 93 mentioned that the hijackers had a bomb, but one of the passengers said that he thinks the bomb was fake. The impact site found no traces of the explosion, the 911 Committee believe that the bomb may indeed forged.
No. 93 in flight black box records show that, when learned on the morning of similar hijacked plane eventually crashed into a building, the crew and passengers tried to regain aircraft control over. Flight 93 recording scripts, one of the hijackers command: Once they will lose aircraft active control of the right to fly the aircraft violent shaking. Soon after, the plane crashed in a field near Shanksville in the morning 10:03:11. The organizers of the attack, Khalid Sheikh Mohammed in 2002 to accept Yosri Fouda, Al Jazeera reporter in an interview that the target of Flight 93 is the U.S. Capitol, code-named “law factory”.
World Trade Center’s three buildings collapsed due to structural damage in the attack that day. Subject to United Airlines Flight 175 hit the South Tower Building 2 (WTO) burned for 56 minutes, about collapse of 9:59 in the morning. North Terminal 1 (WTO) is about 102 minutes after the burning, collapsed on the morning of 10:58 minutes. In its collapse, debris severely damaged near the World Trade Center VII Building 7 (WTO). On the 7th, the building’s structural integrity by the further erosion of the fire, and finally collapsed in 5:20 in the afternoon.

The attack caused a major disruption of the nation’s news organizations and air traffic control. Within 3 days of non-governmental international flights is prohibited to land in the United States. Flight or return flight were diverted to Canada or Mexico. Flooded with a whole day has not been confirmed and contradictory news reports in the media. The most widespread “news” is a car bomb explosion in the U.S. State Department in Washington, DC. May 4, 2006, U.S. District Court judge to make a formal verdict, sentenced to 911 terrorist attacks in the trial of al-Qaeda member Moussaoui to life imprisonment without parole. May 23, a Web site often used by the al-Qaeda announced a period of allegedly Osama bin Laden’s speech recording, his command of 19 individuals to implement the 911 attacks, but he never assigned Moussaoui to participate.
