Reduce the cost of the LED lamp
The main way the cost of the LED chip occupies a main portion of the LED light cost, thereby reducing the LED is to reduce the cost of the LED chips.
LED chip technology development lies in the base material and the epitaxial growth techniques. Substrate material from the the traditional sapphire material, silicon and silicon carbide, the development of new materials such as zinc oxide, gallium nitride. In a few short years, by means of a series of technical improvements, including chip structure, surface roughening treatment and multi-quantum well structure design, LED light efficiency to achieve a great breakthrough.
Low cost silicon substrate, technical progress, but the luminous efficiency are still not satisfied, and if you maintain this pace of development, once they reach a higher level, the silicon substrate to become the most important technology programs become an inevitable choice, companies will also huge economic returns.
Color LED lights
In the high-luminance white LED, a small portion of blue light having a longer wavelength Stokes shift occurs. This is a good thing, which makes the phosphor layer can be used in many different colors LED lamp manufacturers to extend the emission spectra, and effectively improve the LED color rendering index (CRI). Using phosphor white LED high CRI is the cost, because the Stokes shift will cause white LED efficiency is lower than the efficiency of the single-color LED. However, for most lighting applications prefer to use high CRI slightly lower efficiency LED lights.
Improve the reliability of the LED lamp system
The overall efficiency of LED life and reliability through system optimization can be improved.
Light source: compact, efficient, choose the color and output power.
The control and drive: the use of electronic circuitry to achieve a constant current LED driver and control.
Thermal Management: To achieve a longer service life must be controlled LED nodes temperature thermal model calculations and the use of new materials and new technology LED lamp technology hotspot.
The optical element: a lens, a reflector, or a light guide material is that the light focused on the target area, or dispersed in the surrounding, which according to design requirements may be.
Improve the efficiency of the LED lamp power
Whether current limiting type constant current control, power op amp to control the constant current power supply, we must solve the power supply problem. Switching power supply chip work requires a relatively stable DC voltage for its chip supply, the chip operating current ranges from a MA to MA. Like FSD200 NCP1012 HV9910, such chips is high-pressure self-feed, using it is convenient, but the high-pressure feed, resulting in the rise of the IC heat, because the IC to withstand about 300V DC, just a little current, even if an MA, 0.3 watts damaged consumption. LED power in general but about 10 watts, the loss of a few tenths of watts what can the efficiency of the power to pull down a few points. Typical as QX9910. Down to take power, with the resistance, loss resistance, about have losses it a few tenths of watts. There is magnetically coupled transformer on the main power coil a winding, like the auxiliary winding of the flyback power to avoid the loss of a few tenths of a watt of power. This is why isolated power transformer also one of the reasons is that in order to avoid the loss of few tenths of a watt of power, efficiency mention a few points.
With the increasingly serious problem of greenhouse gas emissions, approaching the critical point of the Earth's self-regulating, countries have introduced policies, governments around the world, including China, must without delay the implementation of energy-saving and emission reduction (carbon dioxide), led lights are the most energy efficient green electric light, natural lighting energy saving option, also accelerating gradually reduce the cost and price of LED lights, the speed of its popularity, in 2020, the market share of LED lights will be more than 50%.

| BlackBerry Difficultly to Get Ahead -2 |
| |
4. most consumers do not have to give up the Android and iOS
RIM, the crucial point is to be able to understand the majority of consumers do not give up devices powered by Android and iOS systems.
In fact, most users have already purchased a Apple iPhone5 smartphone, in addition to a lot of users buy the Samsung Galaxy phone, these estimates will not change with other phone. Of course, RIM To want Black Berry10 to succeed, you must be able to attract these consumers. Now it seems, can only wish RIM luck.
5. business users are increasingly turning to Android and iOS
According to a research data show that, in 2012, the number of corporate users to buy Android and iOS devices for the first time more than the number of corporate users to buy Blackberry. Although equipped with a system Android and iOS products owned enterprise users not number of business users, but that the number of corporate users two operating systems together, it has exceeded the BlackBerry and BlackBerry . This result is indeed shocking, but also illustrates the RIM company in the field of business users have been facing the fate of being eaten up.
6. RIM's design is generally
RIM has not known design. Fact, RIM company over the years has been the release of the product, but the design of these products can not be compared with Apple's iPhone and Samsung smartphones. RIM If you can not make a huge change, poor design feeling will become a huge problem BlackBerry10 open market situation.
7. application problems
The application is an extremely important factor in today's mobile field. However, the purpose of generally available application, RIM's Black Berry App World (App Store) is greatly lagging behind Apple's App Store and Google application store. RIM's executives claim that they have been demonstrated to developers BlackBerry10 system, and that these developers are working to add more applications, but in any case, RIM's application store has been very backward, may no longer be able to catch up with Apple and Google and other competitors.
8. Delayed release is a taboo
Black Berry10 will market in early 2013, but in fact, this product should have been listed in 2012. In fact, RIM CEO of Thor Stearns Hynes (Thorsten Heins) has already announced that this operating system postponed to be released next year. Hynes claimed its employees before the release of this operating system will not be allowed to leave, but all may have been too late. The delayed release is a problem, at least let RIM company in the mobile space behind a final consequences is to make the Black Berry10 more unable to catch up with iOS or Android.
9. The market is looking forward to novel products
The RIM the Black Berry10 of the operating system is a catch up with other products, this operating system configuration full touch screen panel functionality, integrated application store and other programs in order to help the user to use a variety of services from music to games. In other words, this in itself does not have anything new. But to say what new is that this will lead to the Black Berry10 fall apart very unfortunate that the the RIM company does not recognize it.
10. the lack of adequate equipment
In the mobile market, the number of plays a very important role. Unless your company name is Apple, or you need to publish as many products to the market in order to seize market share. Unfortunately RIM will only sales (sales and the most they can) Black Berry10 products. Taking into account the large number of mobile phone based on Android system has a market-oriented, RIM, the company and its new products in order to obtain a larger market share in competition with other products may be exceptionally difficult.

10 Reasons BlackBerry Difficultly to Get Ahead
According to foreign media reports, the online edition of the leading U.S. IT magazine "eWeek" wrote today, said the RIM Black Berry10 market success will continue to face difficulties, and analysis of Black Berry10 10 reasons difficult to obtain successful. "EWeek" Web version of the article content as follows:
RIM is pushing the Black Berry10 to enter the market, However, the chances of success of the product may be significantly lower than RIM expected. In the mobile market, RIM has indeed suffered a huge dilemma the Black Berry operating system for the company a few years ago, once favored by the market, but is now being consumers seriously neglected, consumers, Black Berry operating system Android and iOS system compared to the new technology, already very outdated. For RIM, the issue has been very severe, so that the company could only watch as its share price falling as well as market share is declining. Worst, RIM is still not do anything, and therefore will not be able to turn the tide to reverse the plight.
Today, With Black Berry10 about to enter the market, RIM's executives seem to think that has to find a way out. BlackBerry10 is a new operating system will soon be available in January next year. RIM, said that this operating system will be configured to a variety of touch screen mobile phone, and because of obsolete design and a physical keyboard away from the old version of the system will give RIM bring earth-shaking changes.
However, any claim that Black Berry10 will be successful speech is nonsense. Operating system may be better than the old system of RIM's previously launched, but also may configure some of the new features, but a new software is enough to solve RIM difficult situation? Here are 10 reasons the Description Black Berry10 market situation will be difficult to open.
1. IPhone strong presence of
Apple iPhone smartphone is extremely welcomed by the market, but also the desire to grab a huge share of the mobile market with Black Berry10 to bring strong pressure to RIM intends. Apple's iPhone is the top mobile market smartphones after will be Samsung 's GalaxySIII, at the same time, some other mobile phone manufacturers mobile phone products has been a huge market of indifference. RIM executives what grounds that their phone will break through the weight of it?
2. Android enormous threat
Black Berry10 market, Android will likely become the biggest problem for RIM. As the popularity of Android is more prosperous, more and more devices equipped with Android system have also entered the mobile market. Conversely, it also brings more and more pressure to other companies. RIM, late into the touch-screen phone, and now have to compete with many Android products, will certainly face strong pressure of Android.
3. BlackBerry consumers do not want to touch the screen
RIM Company, a very strange thing is that the company's traditional consumer does not want to touch screen devices. In fact, it has always insisted on the use of BlackBerry products the user is also a user who has been like a physical keyboard. However, RIM this was released Black Berry10 new products, trying to attract users who are both looking forward to the BlackBerry experience and look forward to the touch screen panel. But the problem is that these users really exist?

Gas Sensors Used in Industrial, Civil, Environmental Monitoring
The gas sensor is a certain gas volume fraction of conversion into a corresponding electrical signal converter. There are a wide range of gas sensors. The application is quite extensive. Gas sensors have a wide range of applications in civil, industrial, environmental detection.
The gas sensor applications in civil mainly to detect a the civilian gas leak of natural gas, liquefied petroleum gas and city gas in the kitchen , detect microwave food cooking gas to automatic control of microwave cooking food; housing, building, meeting rooms and places of public entertainment to adhere to the carbon dioxide, smoke, ozone and unpleasant gas, automatic operation and control air purifier or fans; rise buildings used to detect fire signs and alarm. Currently, civilian areas is the main application areas of semiconductor metal oxide gas sensors. This is mainly because of the semiconductor metal oxide gas sensors are inexpensive, the performance can also meet the requirements of the home alarm.
Gas sensors in industrial applications are mainly used in the stone in the chemical industry to detect carbon dioxide, nitrogen oxides, sulfur oxides, ammonia, hydrogen sulfide, and chlorine and other harmful gases; semiconductor and micro- electronics industry to detect organic solvent and highly toxic gas phosphine ; hydrogen power industry detection power transformer oil metamorphic process; perishable food industrial inspection meat food freshness; detection of oxygen in the exhaust gases of cars and furnaces industrial control of combustion, to achieve the twin goals of energy conservation and environmental protection ; Highway Traffic detect the driver's breath in the ethanol gas concentration to prevent drunk driving and reduce traffic accidents.
Environmental detection of course, can not be separated from the gas sensor, such as the application sensor detects nitrogen oxides, sulfur oxides, hydrogen chloride, which causes acid rain gases; detect carbon dioxide, methane, nitrous oxide, ozone, Freon and other greenhouse gases; detection of ozone, ozone-destroying gases such as Freon; detect ammonia, hydrogen sulfide and gas unpleasant gas.
In summary, the gas sensors based on their different functions in the civil, industrial, environmental testing has a significant role. After further transformation of the sensor, the scope of its application will be more extensive. We will see in more situations gas sensor applications.

| Tim Cook committed 3 errors (2) |
| |
2. Announced that Bob Mansfield (Bob Mansfield) retirement, but will now be promoted to the rank of "technology" in charge.
Mansfield retired in June of this year. August of this year, he said he would be very rich rewards in the form of a contract system () returned to Apple to continue to work, and is responsible for the development of new products in the future. In October of this year, he got promoted, in charge of a new "technical" team, including semiconductor and other wireless team. Cook said he will be staying for another two years at least.
I do not Mansfield promoted to executives of insider information. However, at the age of 51-year-old announced his retirement (perhaps my antique bar, but for a very famous company by market value in the world, senior vice president, 51-year-old retired is not it a bit early), and then failing to retirement, and then get a promotion, which made me feel very strange, do not know what unknown things in the past six months, Apple management in the end.
Cook should not be on how to manage the company team to develop an orderly plan? If Flowserve Thor resignation, which I can understand, but the the Mansfield things people can not help but think Cook lack sufficient understanding of the situation of the company team. Apple press release announced the retirement of Mansfield before Cook should he go into the details to find out in the end is how is it.
Map of Apple and Siri voice assistant responsible.
For a long time, and I are Apple Map and Siri voice assistant faithful. In the past year, critics who complain about these two products quality, says Jobs will never be allowed to publish such a thing (even though he gave the green light for the two products), and I compared to them defended . Clearly, Apple has had to deal with public relations problems caused by these two products.
In my opinion, Apple map seems even more Apple embarrassed, because there have been so many obvious errors in the product release. All of which are under the supervision of the Forth Thor. Forth Thor's departure may be partly because Cook wanted him to become examples of accountability.
However, Cook responsibilities of these two products where? He has been a lot of reporting and information, but he must Forth Thor frequently asked about these two products. Clearly, the developers of those mistakes a lot of feedback, but are ignored. Why? Cook did not know it? If you do not know, why would not know?
Maybe Cook will admit in private conversation these errors. Perhaps he even said that he has gone from giving his team too much autonomy and hired Broken Witt learned a lesson. Perhaps he would say, October 30 initiatives in order to rectify the errors committed in the past year, he is in a better position the company in the next 10 years.
He may be right. I believe Apple will be able to respond to these changes.
However, the only escape from the reality talent does not attempt to learn from their mistakes. I sincerely hope that the Cook carefully reflect on the things that happened in the past year.
Now look at you, Cook. Doing well.

| Tim Cook committed 3 errors (1) |
| |
After the death of Steve Jobs, a lot of people have become experts in research Jobs, constantly told us that if he were alive, he would do and not how to do it.
There are many pseudo-experts for Apple succession plan claims like Steve Jobs, Tim Cook (Tim Cook) can not as competent encountered in the management of Apple's "innovation" challenges.
I always defend Cook, said he is excellent Apple CEO candidates. I also pointed out, I think Steve Jobs's greatest achievement is left after he died This management team at the helm for Apple.
iOS software Scott, director of Forth Thor (Scott Forstall) is an important member of the team. But now he is gone.
On October 30, I asked Horace de Dieu (Horace Dedieu), he's view messages left on the Forth Thor. He replied (via Twitter) says:
"Seems to be a good idea to Apple faces the biggest threat is that the intense office politics and the ensuing chaos, but I have no information in this regard."
Like others, I have no information in this regard. But I think, Horace judgment on what happened and the reasons may be accurate.
Therefore, timely review of Apple's history, think the Ku Keti pull Johnny Ive (Jony Ive) and the dismissal of Scott Forth Thor was the right decision.
That is, if I did not specify this, then I would think that he was not a fair apples commentator. Although I think Cook so far is excellent Apple CEO, but he is not perfect.
In fact, if you're counting at home, then you will find, in the 13 months since the death of Steve Jobs, Cook committed three big mistake. Let's take a look at these errors.
In the spring of last year hired John Broken Witt (John Browett) served as the Head of the Apple Store.
Broken Witt learned in the morning of October 30, the news of his dismissal by the people of widely praised, this certainly make him feel a little sad. In fact, the hiring him is a mistake from the beginning. CEO of the British Dixon (Dixons) to manage Apple Store? Not find Dub (Dollar General) CEO do?
In February this year, Cook argued that the practice hired Broken Witt: "I had a conversation and a lot of people, so far John is the best candidate, I think you'll like me."
In my view that is not the case. Broken Witt "so far" to defeat the other of which candidate? Critics are worried, Broken Witt will mean towards the Apple store and its employees. I think they worry. Broken Witt does exactly that. This is the first major hiring decisions made after the death of Steve Jobs, Cook, but he blew it.
I have read a few people say: "Well, at least, Cook quickly recognized the error and corrected." Their view is absolutely correct. A lot of not-so-famous CEO also because "their people" once again into the plight of a few years. But disturbingly, Cook hired Broken Witt wrong. This can not help worrying other hiring and firing talent (especially at Flowserve Thor quickly leave).
