摘要
LED由于其自身的耐振动、抗冲击、长寿命和无污染等独特的优点,随着发光效率的提高,其应用面不断扩大。为更准确反映LED光强随发光角度渐变的特性,提出了新的光源迭加模型,经过详细论证证明完全可行,且操作简单,易于实现,只要追迹光线足够多,误差就非常小,效果比较理想,很容易被一般设计人员所掌握和应用。
With improvement of lighting efficiency, LED is consistently cxtendingits application as its peculiar advantage, which including resistance to vibrancy and impact, durable ability, and no pollution. It builds the lighting source model, simulates attenuation characteristic of LED, proves feasible in claborate demonstration. It is an easy way for designer to master and put it into practice.
