摘要
针对复合式抛物面聚光器(CPC)无法在TracePro软件中直接建模的不足,结合TracePro软件特点,对CPC关键参数进行了分析,通过数学模型对参数之间的几何关系进行了推导,得出了计算公式,实现了CPC在TracePro中的建模。将CPC设计成反光杯应用于LED灯具中,可方便地进行光学模拟和分析,进而有效地缩短产品开发周期和开发成本。为CPC设计提供了数学依据,通过建模验证了该方法的可行性,有效提高了设计效率。结果表明,用通过该方法设计出的CPC做成的LED反光杯,可以极大地提高灯具的发光效率。为其在照明领域的发展应用提供了更好的使用价值和前景。
Abstract
The compound parabolic concentrator (CPC) cannot be directly modeled in the TracePro software. According to the characteristics of the TracePro software, the CPC key parameters are analyzed through the mathematical model and the geometric relations among the key parameters are derived. The formulas of CPC parameters in TracePro modeling are obtained. Designing CPC as the reflector cup of LED luminaire is convenient for optical simulation and analysis, with which the product development cycle and development costs are reduced. The formula of theoretical calculation is also given, which makes modeling possible in TracePro software. The result shows that LED reflector cup based on the CPC designed by this method can greatly improve the optical efficiency of luminaires, contributing to the development of the LED lighting industry.
