Luminous efficacy of the LED reaches 90~120lm/W, with good monochromaticity, narrow light spectrum, optional color temperature and good color rendering property.
          2. Less power consumption
              Power of single LED is 1~3W, adopts DC driving, single-tube driving voltage is 3~35V, current is 0.35~1A, with quick reaction speed and high-frequency operation. Under the conditions of same luminous effect, its power consumption is one eighth of that of incandescent bulb, and a half of that of fluorescent tube.
          3. Long service life
              The general light sources work to shine by using electronic light radiation filament, so it is easy to burn and have thermal deposition and light attenuation. While, LED light source is featured with small volume, light weight and epoxy resin encapsulation, can withstand high-strength mechanical shock or vibration, theoretical service life as long as 100,000 hours, greatly reducing the maintenance costs.
          4. Safe and reliable
              Cold light source, no thermal radiation, the light type and angle can be controlled accurately, with soft light, free from glare, no mercury or sodium or other hazard materials. The built-in microprocessing system controls the luminous intensity and regulates the luminous way.
          5. Environmental friendly
              LED is a solid illuminant, is shock resistant, impact resistant, unbreakable. The waste can be recycled, no pollution to the environment.
          6. Low use cost
              LED light source is a bit more expensive than traditional light sources, but you can recoup the investment of LED light source by saving the energy in one year. As it is a maintenance-free light source, you can save the maintenance cost in the following years, greatly cut down the use cost.

          1. 發光效率高
          白熾燈光效為7~14lm/W,熒光燈50~80lm/W,高壓鈉燈80~12lm/W,大部分的耗電變成熱量損耗。LED光效可到達90~120lm/W,而且其光的單色性好、光譜窄,色溫可選定,顯色性好。
          2. 耗電量少
          LED單顆功率1~3W,采用直流驅動,單管驅動電壓3~35V,電流0.35~1A,反應速度快,可高頻操作。同樣照明效果的情況下,耗電量是白熾燈泡的八分之一,熒光燈管的二分之一。
          3. 使用壽命長
          普通光源采用電子光場輻射發光,燈絲發光易燒、熱沉積、光衰減等缺點。而采用LED光源體積小、重量輕,環氧樹脂封裝,可承受高強度機械沖擊和震動,不易破碎。理論壽命達10萬小時,可以大大降低燈具的維護費用,避免頻繁換燈。
          4. 安全可靠性強
          冷光源,無熱輻射,能精確控制光型及發光角度,光色柔和,無眩光;不含汞、鈉元素等可能危害健康的物質。內置微處理系統可以控制發光強度,調整發光方式。
          5. 有利于環保
          LED為全固體發光體,耐震、耐沖擊不易破碎,廢棄物可回收,沒有污染。
          6. 使用成本低
          LED光源比傳統光源價格稍高,但是用一年時間的節能可收回光源的投資,LED屬免維護光源,可節省以后幾年的維修費用,大大降低了使用成本。
