4、提高光通量利用率，最大限度的降低綜合照明成本。

4, improve the utilization rate of luminous flux, the maximum reduce comprehensive lighting costs. 

雖然LED光源不如某些傳統光源光效高，但由於LED光源發光方向性強，可利用率高，所以只要通過合理的光學處理，最大限度的利用其光通量，在照度方面，LED完全可以達到功能照明的要求。

LED light source, though less certain traditional illuminant light efficiency is high, but the LED light source intensity, utilization rate is high, so as long as through reasonable optical processing, maximum use of the luminous flux, in terms of intensity of illumination, LED can completely meet the requirements of function of lighting. 

在相同的條件下測試3WLED和35W鹵素燈杯的照度。在3米之內LED光源的中心照度比鹵素燈杯高很多，在實際應用中，燈杯的常用照明範圍在1-3米，從圖上可以很容易的看出3W LED燈杯照明效果明顯好過35W鹵素燈杯，這主要是因為鹵素燈杯沒有很好的利用其光通量。

Under the condition of the same test 3 wled illumination and 35 w halogen lamp cup. Within 3 meters of LED light source at the center of the intensity of illumination is higher than halogen lamp cup a lot, in practice, the commonly used lighting lamp cup range between 1 to 3 meters, can be easily seen from the figure 3 w LED lights cup lighting effect significantly better than 35 w halogen lamp cup, this is mainly because no good use its luminous flux halogen lamp cup. 

5、解決大功率LED的散熱技術，最大限度的延緩大功率LED的光衰

5, solve the high power LED heat dissipation technology, the maximum delay of high power LED light failure 

大功率LED是LED產業未來發展的一個方向，目前因其較高的光效和優越的流明維持率而成為各大廠商競相開發的產品，但大功率LED對散熱技術要求較高，環境溫度達到一定的限度就會很快產生光衰，直接導致LED壽命的下降，目前僅1W和3W大功率LED小量應用於市場，而5W和10W的大功率LED還停留在實驗室階段。只有解決大功率LED的散熱技術，最大限度的延緩LED的光衰，才能大面積的推廣大功率LED的應用。

High power LED is a direction for the future development of LED industry, at present due to its high light efficiency and superior lumen maintenance ratio and become each big manufacturers to develop products, but high power leds for heat dissipation technology demand is higher, the environment temperature reaches a certain limit will soon produce light failure, directly LED to a decline in the LED life, is now only 1 w and 3 w high power LED small amount applied to the market, and the 5 w and 10 w high power LED is still stay in the laboratory stage. Only solve the high power LED heat dissipation technology, the maximum delay LED light failure, the application of high power LED to widespread promotion. 

現階段，LED已經能够 在一大堆場所当做傳統光线选用，特別是大最几千瓦LED的出現，提速了LED结合在一起傳統灯饰照明设备光线的高速度，也会使LED在室內灯饰照明设备的大面積應用變得現實，隨著整個行業的不斷成长期，LED產品開發的縱向深入浅出，大最几千瓦LED在價格和光效上還會有过大的變動大幅度，加上國家政公司策的力推導向，社會輿論的積極宣傳，我們有理啊由说实话，未來十几年內，LED一段會像現在的螢光燈一樣，飛入尋常老百姓们家。

At present, the LED can be used to replace the traditional light source in many places, especially the emergence of high power LED, accelerate the speed of leds to replace traditional lighting source, had the widespread application of indoor lighting LED becomes reality, as the industry matures, vertical depth of LED product development, high power LED on the price and photosynthetic efficiency, still a lot of variations and national policy guidance, positive public opinion propaganda, we have reason to believe that, in the next decade, the LED will be like now of fluorescent lamps, flying off the shelves.
