【摘要】:减光式烟雾报警系统中的准直系统收集大角度红外光线获得平行光,保证光线长距离传输不发散,逐点计算并优化减光式烟雾报警准直系统。针对理想点光源,依据等光程原理及折射定律,求解烟雾报警准直系统初始结构的离散数据点,将离散数据点拟合成自由曲线。利用光学仿真软件建模并优化准直系统的初始结构,得到较好的LED自由曲面准直系统。自由曲面准直系统的厚度为20mm,口径为28mm,准直角度为±1.5°,光能效率高达89.82%。
[Abstract]:The collimation system in the light-reducing smoke alarm system collects large angle infrared light to obtain parallel light to ensure that the light is transmitted over a long distance and does not diverge point by point to calculate and optimize the anti-light smoke alarm collimation system. According to the principle of equal-path and the law of refraction, the discrete data points of the initial structure of smog alarm collimation system are solved according to the ideal point light source, and the discrete data points are combined into the free curve. The optical simulation software is used to model and optimize the initial structure of the collimation system, and a better LED free-form surface collimation system is obtained. The thickness, caliber and collimation angle of the free-form collimation system are 20mm, 28mm and 卤1.5 掳respectively.
