Luminous Efficacy of Radiation for White LEDs with Two Primary Colors

两基色白光LED的光视效能的研究

Nowadays the main disadvantages of plasma display panel ( PDP) are the low luminous efficacy in sustain period and excessively high power consumption, which not only is a waste of energy, but affects the life time as well.

目前，等离子体平板显示器（PDP）存在的主要问题是维持期白光光效过低，功耗过大。很高的热耗散不仅浪费能量，而且影响其使用寿命。

Due to its high luminous efficacy and tong lifetime the high-power high-frequency electrodeless lamp has remarkable energy saving effect.

大功率高频无极灯光效高、寿命长，节能效果显著。但其灯泡较高的工艺要求一直是阻碍其批量生产的难题。

The synthetic range of the white LEDs with two primary colours in chromaticity coordinate is determined by colour matching calculation, and the selective range of two primary colours is determined to obtain high luminous efficacy of radiation for white LEDs.

通过计算确定了可合成白光的两基色的选取范围，确定了得到高光视效能的白光LED的两基色的选取范围。

High luminous efficacy, average life-span 8000 hrs.

高光效,长寿命, 平均寿命长达8000小时.
