| 摘 要： | 半导体发光二极管发出的光谱能量分布曲线和视见函数可以近似地表示成适当参数的高斯函数。在测出LED总光通的情况下,我们可以积分算出LED的光视效能、功率效率和量子效率。对GaP,GaAs0.62P0.38和Ga0.68Al0.32As三种LED进行了计算,其结果与直接求面积法所得数据比较,表明两者符合较好。

| Abstract: | The visibility aurve and the spectral energy distribution curve of light emitted by semiconductor diodes are approximated by Gaussian functions with appropriate parameters. The buminous efficiency and both power and quantum efficiencies of luminescence of LED can then be evaluated by direct integration when the total luminous flux was measured. Comparison of the calculated values with those obtained by means of planimeter shows fairly good agreement for three kinds of LED: GaP. GaAs0.62P0.38 and Ga0.68Al0.32As. |
