Friedrich Engels once said: "History is everything to us" and the 90-year history of the Communist Party of China is also the inspired history of the Chinese revolution, the unyielding history of Chinese construction and the magnificent history of Chinese reform. It is the precious wealth of the Party, the powerful spiritual force that can be applied to reality, and the important resource of promoting the great cause of socialism with Chinese characteristics and constructing great new projects. 

The Party's exploration and efforts, successes and setbacks, experiences and lessons during its 90-year history provide historical reference for promoting scientific development and social harmony. It is also related to achieving new victories in building a moderately prosperous society in all aspects, providing useful enlightenment for improving the scientific level of Party building and consolidating the Party's position, and the spiritual impetus for dealing with ideological challenges and consolidating the common ideological based on the entire Party and people of all ethnic groups. In other words, the 90-year history of the Party can provide endless wisdom and power to continue to move forward.

Attaching great importance and cherishing the Party's history, absorbing the fruits of the Party's history and using historical experience to guide and promote future development is the fine tradition and political advantage of the Party. The Party has now been established for 90 years and in a new period of the new century the Communist Party of China should run a virtuous government for the people and always remain the strong leadership core of socialism with Chinese characteristics. 

One important point is to effectively absorb the fruits of the Party's history. The Party can perform well in various tasks and bravely take historical responsibility only through deeply understanding its own history. Currently, the majority of Party members and cadres, especially leading cadres at all levels, are learning from the history of the Party, and the key is to grasp the following aspects:

The Party has always complied with the tide of historical development and changed with the times. Historical experience shows that whether or not a political party can become a progressive force to move forward social and historical development fundamentally depends on whether it can follow the development direction and trend of the times and strive to stay ahead. The fundamental reason why the Party has accomplished remarkable achievements and withstood various types of stern tests during its 90-year struggle lies in that it has always followed the tide of historical development and changed with the times. Major changes have taken place in the world economy, politics, culture and technology, as well as the environment at home and abroad related to China's reform and opening-up. Given such a complicated situation, China should further develop a world vision and strategic intellectual capabilities as well as follow the correct trend for the development of China and the world. It should not to lose its direction or miss its goals amid distractions in order to seize opportunities, develop itself and accomplish new achievements despite various challenges.

Multiple LED industry bubble risk capital flock to the early "Since last year, back and forth almost seventy-eight investment institutions from different backgrounds come over us, to give our investment." Likeda LED manufacturers in Shenzhen Optoelectronics Co., Ltd. General Manager Koukai Tai told the "Economic Information Daily" reporters, deserted for some time picking up again, the LED industry, multi-channel capital is flocked.

Ministry data show that in 2010 the momentum of rapid investment in the LED industry, the annual investment of 166.1 billion yuan, up 57.5%,Lottery Center the growth rate increased 54.7 percentage points over the previous year; 2011 to April, LED industry to maintain high investment growth, investment has more than 300 million, more than 90% growth rate, become a veritable hot spot for investment.

Cowin Venture Capital Partner and Managing Director Ding Baoyu in the "Economic Information Daily" reporters, said the LED industry is currently investing in the formation of another peak. And compared to the peak before the investment, greater investment in this round of the peak, the participants involved in professional investment institutions,Plate Heat Exchanger Manufacturer other industry players, foreign and private capital, investors are more diversified.

Ding Baoyu that the multi-channel capital to compete for the LED industry, is the fancy LED industry a bright future. Institute of Engineering LED industry, industry bodies, the report predicts that by 2011 the market scale of China's LED industry will reach 120 billion yuan, "five" during the LED industry is expected to achieve the goal of quadrupling.

However, some industry insiders believe that the current LED industry investment bubble has emerged. "The current investment climate there are some impetuous, we all want to make quick money." Kou Kaitai such an expression of this round of investment boom of the LED industry unrest; NVC chairman Wu Changjiang, said, LED industry investment bubble has emerged, investors should not blind shots.

Secretary-General of China Association of Lighting Liu Sheng-ping in the "Economic Information Daily" reporters, currently interested in the outside world pushed up the LED market, lighting market size of China's total was 3,000 million,LED light Manufacturer but the body of the LED market has been "blown large "to the trillion scale. At present all aspects of production for the LED market statistics for the lack of scientific data, and there is a lot of double-counting phenomenon.

In such a "good prospect" of encouragement, and the brightest capital have entered the LED industry, has led to the emergence of industrial investment bubble. One industry to the "Economic Information Daily" reporters, said the industry's market size is more recognized around 120 billion, but the size of the country known to produce far more than that figure. While in the "five" in the context of energy saving, LED products will gradually replace traditional products, but it is a long process. Therefore, the current investment should be alert swarmed the situation.

Lottery on the show before college entrance essay re-entry by the community more and more attention following the Spring Festival Gala "Belle Epoque" staged "gross return of 5 million winning lottery Peas" story caused by all the people thinking about the integrity of the lottery, the integrity of sports lottery owners Zhao Shubing more stories on June 7 2011 college entrance examination board papers, Volume II to become the national language essay topic,The original Duijiang once again aroused the people concerned about lottery credit.

Lottery credit college entrance essay finalists on June 7 in the just-concluded college entrance examinations in the language, Volume II of the national essay entitled "to buy the lottery." Volume II in 2011 with the country's provinces and cities including: Guangxi, Guizhou, Yunnan, Gansu, Inner Mongolia, Qinghai, Tibet. Essay topics is as follows: Drawer bought tickets Title: buy the lottery tickets required: September 12, 2010, a Beijing store owner for a lottery Lottery Loaning a 1024 yuan to buy a football lottery the next day he learned of this lottery 5.33 million yuan prize, the first time for buyers to call, and the winning tickets to the buyer. He became a lottery sales but also "the most honest of the owners."

Zhao Shubing the integrity of the story was brought to the silver 2011

白光 LED 的開發
對於一般照明而言，人們更需要白色的光源。 1998 年發白光的 LED flood light 開發成功。這種 LED 是將 GaN 晶片和釔鋁石榴石（ YAG ）封裝在一起做成。 GaN 晶片發藍光（ λ p =465nm ， Wd=30nm ），高溫燒結製成的含 Ce3+ 的 YAG 螢光粉受此藍光激發後發出黃色光發射，峰值 550nm 。藍光 LED 基片安裝在碗形反射腔中，覆蓋以混有 YAG 的樹脂薄層，約 200-500nm 。 LED 基片發出的藍光部分被螢光粉吸收，另一部分藍光與螢光粉發出的黃光混合，可以得到得白光。現在，對於 InGaN/YAG 白色 LED ，通過改變 YAG 螢光粉的化學組成和調節螢光粉層的厚度，可以獲得色溫 3500-10000K 的各色白光。

LED 燈消耗電力較低, 產生嘅熱力亦都很低, 所以比一般鎢絲燈膽長壽, 直接減低汽車要維修嘅次數 (亦減輕汽車電力系統嘅負擔)

LED比傳統鎢絲燈膽亮得快, 所以放喺尾燈係會有安全作用 (後面D司機可以更早見到你). 呢個係暫時汽車界對LED燈最強調嘅一個point.

喺Design 角度, 因為LED燈比較細, 燈嘅組件(燈罩, cable/wire, etc) 亦都可以做得flexible D. 用LED燈嘅燈罩可以做得多角度一D, 彎位多D, 咁架車望埋去又靚D, sexy D.

LED嘅燈可以唔需要燈罩去決定盞燈嘅顏色. 所以有D新車可以成個尾燈罩都透明, 但到brake 時紅色嘅LED燈就會由靜止時嘅透明轉紅 (可以做埋夜晚細燈同尾Fog Light), 打燈時黃色嗰組LED燈又會負責.

其實而家車頭都有用LED 燈. 997 嘅911 Turbo 下麵driving light 已經係LED. Lexus LS600h 同 Audi R8 今年直頭會將LED 用喺低燈同高燈!

新霓虹燈與LED燈優缺點的比較和競爭
以下針對霓虹燈與LED燈相關比較，加入最新的LED技術進去比較，不是之前大家在網路中見到的哪份資料。
1. LED光源有100000小時壽命嗎?
按光衰7%，實際只有約50000小時。按光衰3%，實際運用可以達到80000小時。
2. LED不會發熱嗎?
會，需散熱。
3. LED可取代白熾燈嗎?
光通量，光效和顯色性可以，但目前太貴且近幾年不會有所下降。但可以通過提高產品的光通量從而降低替換白熾燈的成本。
4. LED light 可作普通光源簡單地使用嗎?
不行，要驅動電源，光學和熱傳導配合。
5. 二種光源性能和優點比較
霓虹燈的優勢已被LED覆蓋，但LED燈目前價太高。
6. 二種光源的電源比較
LED低壓好，但防水性差和載電流過大。大顆粒1瓦的LED單燈輸入電流在350mA。
7. 二種光源的控制技術比較
LED易實現，但霓虹燈成熟。
8. 二種光源的穩定性比較
LED不一致性大，霓虹燈相當穩定。少數產家可以做到相對穩定，比如用CREE 跟AOD晶片相結合，取各自晶片的優點。
9. 二種光源的價格比較
LED較貴，但黃色和紅色已相當，主要貴的是LED白光。
10. 二種光源戶外使用比較
LED防水性差是戶外使用的致命弱點。
11. 二種光源目前市場的比較
全球照明產品年產值420億美元(中國150億美元)LED光源現比例小於1％。

LED色溫基本常識
色溫的定義：
以絕對溫度K來表示，即把標準黑體加熱，溫度升高到一定程度時 該黑體顏色開始深紅-淺紅-橙黃-白-藍
，逐漸改變，某光源與黑體的顏色相同時，我們把黑體當的絕對溫度稱為該光源的色溫。

不同光源環境下的色溫：

常見照明燈具所採用的色溫

鹵素燈 3000k
鎢絲燈 2700k
高壓鈉燈 1950-2250k
蠟燭光 2000k
金屬鹵化物燈 4000-4600k
冷色營光燈 4000-5000k
高壓汞燈 3450-3750k
暖色螢光燈 2500-3000k
晴空 8000-8500k
陰天 6500-7500k
夏日正午陽光 5500k
下午日光 4000k
不同色溫下的光色：

低色溫：色溫在3300K以下，光色偏紅給以溫暖的感覺；有穩重的氣氛，溫暖的覺；當採用低色溫光源照
射時，能使紅色更鮮豔。

中色溫：色溫在3000--6000K為中間，人在此色調下無特別明顯的視覺心理效，有爽快的感覺；所以稱為
"中性"色溫。當採用中色溫光源照射時，使藍色具有清涼感。

高色溫：色溫超過6000K，光色偏藍，給人以清冷的感覺，當採用高色溫光源照時，使物體有冷的感覺。

單色光 LED 的應用
最初 LED light 用作儀器儀錶的指示光源，後來各種光色的 LED 在交通信號燈和大面積顯示幕中得到了廣泛應用，產生了很好的經濟效益和社會效益。以 12 英寸的紅色交通信號燈為例，在美國本
來是採用長壽命，低光效的 140 瓦白熾燈作為光源，
它產生 2000 流明的白光。經紅色濾光片後，光損失 90% ，只剩下 200 流明的紅光。而在新設計的燈中， Lumileds 公司採用了 18 個紅色 LED 光源，包括電路損失在內，共耗電 14 瓦，即可產生同樣的光效。
汽車信號燈也是 LED 光源應用的重要領域。 1987 年，我國開始在汽車上安裝高位刹車燈，由於 plate heat exchanger 回應速度快（納秒級），可以及早讓尾隨車輛的司機知道行駛狀況，減少汽車追尾事故的發生。
另外， LED 燈在室外紅、綠、藍全彩顯示幕，匙扣式微型電筒等領域都得到了應用。
