smd high power led and dlp technology

Strong technology as a new big-screen video, LED lights source DLP splicing products have been one of the industry the focus of industrial innovation. Era light LED technology is not only a simple change of the light source technology, it will fundamentally change the practical performance of the DLP splicing products, or even create many new applications. LED light source DLP Video New in the end they will give industrial customers to bring a new surprise which unexpected?

Lower cost of ownership

smd high power led and dlp technology

The LED high bay light source used in DLP Video Wall product is the first significant change is the user’s cost is significantly reduced. Although the use of LED technology will make the first investment of DLP Video Wall project increased by 30%, but the LED light source to achieve a life of 60,000 hours, is equivalent to about 20 times that of traditional mercury lamps. That is the whole life of the customers in the DLP Video Wall will save at least 20 bulb replacement costs. This fee is not only enough to offset the LED technology resulting from the rising cost of DLP splicing unit can save a lot of money invested.

Another feature of the LED light source technology is the three primary colors of light independently. This makes the DLP projection system to no longer need the splitter device of the color wheel. As a mechanical operation of the product, color wheel maintenance and replacement frequency is caused by the customer an important part of the cost. Although the color wheel components are not DLP Video Wall core supplies, but no color wheel, LED lighting products, the economy still can not be ignored.

The long-life LED light source also makes DLP Video Wall, a significant reduction in maintenance frequency. The annual maintenance number at least a 50% reduction. This will also serve as important “money” node, one of the important added value for customers purchasing LED light source products. In addition, as an efficient light source products, LED down light will also have a higher luminous efficiency, higher light utilization efficiency, which reflects the “low cost” feature of the other part of the conservation of electricity.

Higher system reliability

LED light source of the product itself is a solid cold light source products. Its high efficiency, low heat, solid-state form is not accidental damage. Traditional mercury lamp light source has the vulnerability of ordinary light bulbs, high product temperature in highlighting the work of state, is also easier because of accident damage, burning, or burst. The solid-state light-emitting LED light source features a significant increase in the stability of the light source.

With traditional mercury lamps products, LED light low-voltage DC pulse drive. The power supply section does not contain high-voltage high-current components, the power of life and stability are more controllable. Combination of the three primary colors of natural light-emitting LED light source, and no mechanical color wheel component splitting, making the LED light source part of the power supply, control and spectral three aspects go beyond the traditional mercury lamp stability.

LED light source, the three primary colors independent light-emitting characteristics of the work makes it even a “light bulb” fails, the machine is still in the state of the lack of color display. This is the traditional single-lamp DLP splicing unit once the light bulb burned, in sharp contrast to the situation of not work. The lack of color display characteristics, making the light accidents of LED light source can protect customers’ losses to a minimum or even no loss. LED light source products and a simple single-lamp DLP splicing unit, its reliability is closer to the Lamps backup system.

Green environmentally friendly low-carbon

The LED light source technology is well-known green technology. The characteristics of the semiconductor manufacturing process, to make it easier the control of toxic metals, unlike the traditional mercury lamp, once the damage is likely to cause the leak of the toxic elements of the internal mercury lamp. As semiconductor components, LED light source can also be recycled, one of the important metal elements can re-enter the smelting aspects of regeneration.

In addition, LED light products or high luminous efficiency light source products.

In the same light conditions, with lower power consumption. Moreover, LED light source using digital pulse light, independent of the three primary colors, and only when the DLP light valve chip DMD certain colors of light, LED light source before work. This is very different to work with traditional mercury lamps continued to ignite. LED light source is not continuous, luminous valuable only when needed, to enable them to better meet the needs of the future economic development of low carbon environmental protection.

More gorgeous bright screen

The LED light source is a typical wide-gamut light source, its color effect is far more than the traditional mercury lamp products. Do not need color wheel for additional filtering characteristics, are also better able to protect the entire DLP-ray machine system can accurately restore the excellent color. The giant ocean LED light source DLP splicing products also has 100

How the junction temperature is produced in SMD high power LED

 

How the junction temperature is produced in SMD high power LED

 

LED heat because the added energy is not completely converted to light, but part of the conversion into heat. SMD high power LED light effect only 100lm / W, its electro-optical conversion efficiency of only about 20 to about 30%. That is about 70% of electrical energy into heat energy.

 

Specifically, the generation of SMD high power LED junction temperature is caused due to two factors.

 

1. The internal quantum efficiency is not high, and is compound when electrons and holes, and cannot be 100% to generate photons, commonly referred to as “leakage current” which PN carrier in the composite rate. Leakage current multiplied by voltage is the power of this part, which is converted into heat, but this is partially accounted for the main component of the internal photon efficiency is close to 90%.

 

2. Internally generated photons cannot be all shot to the external of the chip and the last is converted into heat, this part is the main, currently known as the external quantum efficiency is only about 30%, most were converted to heat.

 

Although the incandescent light efficiency is very low, around only 15lm / W, but it almost all the electrical energy into light energy radiate out, because most of the radiation is infrared, light efficiency is very low, but exempt cooling problems.

 

The most common civilian light is the incandescent lamp, which is our ordinary bulbs. If the SMD high power LED is to replace incandescent bulbs, it is necessary to develop a in terms of the lamp shape or appearance of similar bulbs and incandescent bulbs, which is often referred to as led high bay bulb. Imagine, Bulb market is very huge.

Suspected of killing Afghan civilians U.S. soldiers smd high power led face charges this week

Suspected of killing Afghan civilians U.S. soldiers smd high power led face charges this week

U.S. soldier suspected of killing 16 Afghan civilians, according to U.S. media reports, Robert Jaspers in the 19th to meet with defense counsel. Previously he had been sent to Levin, Fort Worth, Kansas military prison, waiting to be charged. Military officials say the allegations in the week smd high power led.
Jaspers weekend kept in solitary confinement, the military prosecutors are preparing for the proceedings. Jaspers has been surrendered to the military custody. He alleged shot at, assassinations and burned civilians, including women and children. U.S. officials said his atrocities spread to several villages in Kandahar province led high bay.
The prosecution service has not made any public statements on the matter, but U.S. President Barack Obama said he has instructed the military to actively deal with this case of public prosecution. Panetta, U.S. Defense Secretary, said that the suspects could face the death penalty smd high power led.
38-year-old Bear Stearns is married and has two children. Several of his lawyers did not deny allegations by Jaspers, but lawyers say they will comb the the Jaspers army experience to determine the cases and what factors This means that lawyers may lead to mental health problems out of control on the grounds for his defense. They pointed out that Jaspers had served in Iraq three times, serving in Afghanistan, suffered brain injuries and a serious foot injury.
It is reported that 9.11 a few months after the event, the Jaspers to give up a seemingly promising future career in the financial industry, joined the U.S. Army. Some people who know him puzzled. Now, with this period of his military career seems about to end, those who knew him and another thing that puzzled: how could he that in Afghanistan, U.S. soldiers shot and killed innocent civilians.
Jaspers to call him “Bobby” in Ohio, hometown neighbors and colleagues in Seattle near military bases that he is a trustworthy soldier fighting for those who knew him, his behavior him a different person with their eyes, so that the great contrast is simply unacceptable.
Jaspers sergeant grew up in Nor wood, Ohio, residential and Jaspers home across the two Potusaite said, this is not like what he has done, who knew him feel the heart like a knife twist. She said, “I see this message in the news, I still do not believe that is true, because the” Bells “and” Robert “is a very common name, but when I saw his close-up photos, he straight front of the eyes, the smiles on their faces when I said yes, that cute little Bobby. ”
Norwood is a middle-class town near Cincinnati, where the mountains rolling, a lot of residential porch alone houses. The town is very quiet during the day can even hear standing in the sounds of pigeons cooing on the wire. The Jaspers child a place to live with her family only two separated, he was a boy behaved the children of this neighborhood 82-year-old’s Potusaite. She remembers the Jaspers had to accompany his granddaughter home, school and other neighbors of the boys throwing the football on the streets of Ivanhoe. The Jaspers temper very good, very quiet, very little, and do not like noisy; he is a good child, she said smd high power led.
Bells High School is Norwood High School, where he joined the school football team, very popular with other players like. Currently living in Norwood, 37-year-old resident of Dublin, was his teammate. Berlin said that Jaspers is that we all like. “He is the captain, brilliant smile, his time is always great temperament.” According to Dublin, Jaspers football is played well, Middle School that got the league award. He enrolled in military history.Dublin recall that Robert had repeated discussions with the teacher in a class war details.Dublin said, from the American Revolutionary War to the Battle of Bunker Hill, the name of all the generals and battle all remember.
However, some people can not understand Jaspers Why participate in the Army, not to mention he is a parameter on the Ohio State University, embarked on the career path of the financial advisor of the military. His high school graduating class of about 125 students, most of them went to college, very few people to join the army. The military road is not prominent in the atmosphere of the class.
Michael Bligh, 35-year-old Vince is Jaspers friends and neighbors in Ohio. Kobe says Vince when he was two years old, Jaspers-year-old understanding of “Bobby”. Brian Evans is still living in single-family brick house across the street from Jaspers home. He and Dublin will recall, the Jaspers had to help a disabled care community. Jaspers in 2002 to join the army after the leave for boot camp the night before, he has been to call Brian Evans. Kobe says Vince, Jaspers was said to him, he enlisted the issue of their own to join the army has a real sense of pride.
