| 摘 要： | LED作为新兴光源,与传统光源相比在自身结构和发光特性上很不相同.由于LED本身的自吸收效应以及积分球内挡屏带来的测量误差,沿用传统的积分球光通量测量装置来测量LED的光通量误差较大.应对传统积分球装置内光源的位置和挡屏做调整以减小光通量测量误差.由软件模拟的数据和理论推算证明应将LED放置在积分球内壁且与探测器探头在同一平面内成90°.

| Abstract: | Light emitting diodes(LEDs) are promising light source for energy saving lighting.Since the geometry structure of LEDs is different from traditional light source,the conventional luminous flux measurement by integrating sphere is challenged due to problems: great absorption of LED itself and optical shield,and the consequently self-heating.By removing of optical shield and relocating the LED from sphere centre to sphere wall where perpendicular to the sensor in a same plane,the above two problems are solved.Optical simulating proves this new method is feasible. |
