DLP投影設備歷經近20年的開展，近幾年逐步受到了LCD類產品的嚴重沖擊，為了應對商場環境的改變，選用LED光源的DLP投影設備在近來三年內得到了大規模的推行和運用。
DLP projection equipment after nearly 20 years of development, gradually in recent years has been a serious impact on LCD products, in order to cope with the market changes in the environment, using LED light source DLP projection equipment in recent three years has been the promotion and application of large scale.
盡人皆知，傳統DLP投影設備最為人所詬病的即是其選用的UHP光源，6000小時的平均壽數致使了用戶的運用本錢始終無法下降，而LED光源則以10倍于UHP的運用壽數，極好的處理了這個疑問。但現在的LED光源是不是就白璧無瑕了呢？在運用中又要留意哪些方面呢？
Known to all, the traditional DLP projection equipment most criticized is the use of the UHP light source, the average life of 6000 hours due to the user's use of cost has not decreased, and the LED light source is at 10 times the UHP using his excellent handling this question. But now the LED light source is not a flawless white jade? In use and pay attention to what?
一、亮度和色域的選擇
First, the choice of brightness and color gamut
LED光源雖然在傳統的野外LED 顯現屏中早已達到了K級流明的亮度，但是在DLP的運用中現在還遍及停留在600-800流明這個區間內（高亮作業形式），所以關于運用環境的環境光線要做更嚴厲的操控，以便將客戶關于LED光源亮度缺乏的敏感度降到最低。
Although the LED light source in the traditional LED display in the field has already reached the level K lumens brightness, but in the use of DLP is still stuck in the 600-800 lumen throughout this range (highlighted work form), so on the use of environmental light to do more strict control, so that the customer on the LED lack of brightness of light source the sensitivity to a minimum.
一起因為LED光源的寬色域特性，使得咱們有機會在更雜亂的環境中進行運用。若環境光源是通常的冷白光或者白熾燈，那么主張可將色溫調整在7500-9300K的規模，使人眼感受的亮度更高、顏色更艷麗。
Because of the wide color gamut of LED light source, we have the opportunity to use in a more cluttered environment. If the ambient light is usually cold white light or incandescent lamp, then advocate the color temperature can be adjusted in the scale of 7500-9300K, so that the human eye to feel a higher brightness, color more gorgeous.
二、散熱
Two, heat dissipation
LED光源因為光譜特性，致使在平等亮度的狀況下，光源部分發生的熱量要高于UHP。所以其關于全部投影顯現單元的散熱規劃請求以及環境溫度的操控請求也就更高。現在主流的散熱方式主要是風冷式和水冷式兩種。應該說各有優缺點。風冷式對比傳統、老練，水冷式散熱功率略高于風冷式，但是規劃難度較高，長時間運用的可靠性有待查驗。
LED light source because of spectral characteristics, resulting in the case of equal brightness, the light source part of the heat is higher than UHP. Therefore, the requirements of the whole projection display unit for the heat dissipation planning and the control request of the environment temperature are higher. Now the main way of heat dissipation is air-cooled and water-cooled two. It should be said that each has advantages and disadvantages. Air cooling type contrast traditional, sophisticated, water-cooled cooling power slightly higher than air cooling, but the planning is difficult, the reliability of a long time to be checked.
三、保護
Three, protection
傳統的UHP光源因為壽數較短，亮度衰減較快，致使在投入運用后，需求較高頻率的定時調試，才能將亮度、顏色均勻性維持在必定水準。而LED光源的高壽數、低衰減特性極好的改進了這種狀況，一起因為沒有色輪，也就不必思考長時間運轉的塵埃關于光機輸出顏色造成的影響。這么就大大節省了保護所需求的人力開銷。
UHP the traditional light source because life is short, brightness decay rapidly, resulting in the operation, the timing demands a higher frequency, brightness, color uniformity can be maintained in a certain level. The number of LED light source, improved high low attenuation characteristic of excellent situation together, because there is no color wheel, you don't have to think about the influence of long time operation of the dust caused by the machine output color. So, the demand for protection of the human cost is greatly reduced.
四、運用本錢
Four, the use of capital
因為LED光源的壽數達到了60000h，并且沒有色輪，所以理論上在設備的正常運用周期以內不必再思考耗材的開銷，
Because the LED light source life reached 60000h, and no color wheel, so the theory within the equipment's normal use cycle no longer thinking supplies cost,
綜上所述，LED光源投影機在運用效果、保護本錢方面相比UHP邁進了一大步，只要在光源亮度方面趕快獲得打破，能夠預見其在必定時間內將主導全部高端大屏幕拼接商場。
In summary, LED light source projector than in the use of cost UHP protection effect, a major step forward, as long as the light brightness as soon as possible was broken, it will lead to anticipate all the high-end large screen splicing in a certain time shopping mall.
