  • luminous : adj. 1. 發光的；明亮的；照耀著的；輝耀的。2. 明白易懂的；有啟發性的。3. 明快的，爽朗的。4. 光明的，燦爛的。adv. -ly ,-ness n.
  • efficacy : n. 效力，功效。
  1. High luminous efficacy, average life - span 8000 hrs

    高光效，長壽命，平均壽命長達8000小時。
  2. The high - intensity - discharge ( hid ) lamps are widely used in lighting system for the high luminous efficacy, long life and good color rendering. high - pressure - sodium ( hps ) lamps have the best combination of the above properties and are considered as ideal light sources. therefore the design of the electronic ballast for the lamps is an important part of the green lighting project

    高強度氣體放電（ hid ）燈以其光效好、壽命長、顯色性好而在照明領域得到廣泛應用，高壓鈉燈（ hps ）即為一種具有上述優點的理想光源，而設計與之相匹配的電子鎮流器是實施綠色照明工程的重要組成。
  3. Luminous efficacy of a source of lighting

    光源輝度效力
  4. Luminous efficacy of a source

    發光效能
  5. High pressure sodium lamps ( hps ) are notable for their high luminous efficacy, good color rendering and long life. but the traditional ferromagnetic ballast for hps lamps due to lower power factor, high igniting current, lower efficiency, and large size, cannot satisfy the requirements for green energy

    高壓鈉燈以其光效高、壽命長、光色好等優點而備受矚目，然而，與之相匹配的電感鎮流器由於功率因數低、體積大等諸多缺點，已不能滿足人們對綠色能源的要求。
