[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 鹵1.5 擄respectively.
