基于热仿真的工业用光源寿命设计与分析

Life Design and Analysis of Industrial Light Source Based on Thermal Simulation

工业用光源常常对寿命、稳定性要求较高。LED以其优秀的低能耗、高响应速度、干净、环保等诸多优点被广泛应用在工业光照方案中解决实际问题。然而,由于科技的进步设备越来越小型化、微型化,LED光源本身结构及应用场合越来越紧凑,就必不可免的会遇到散热问题。传统依靠热力学公式及经验进行纯手工计算的热设计几乎是不可能完成的任务。本文提出了一种针对工业用光源寿命设计的热仿真分析方法,通过与试验对比,验证了其准确性和可行性。

Industrial light sources often require high life and stability.LED is widely used in industrial lighting solutions to solve practical problems because of its excellent advantages of low energy consumption,high response speed,clean,environmental protection and so on.However,due to the progress of science and technology,equipment is becoming more and more miniaturized,LED light source structure and applications are becoming more and more compact,it is inevitable to encounter a problem of heat dissipation.It is almost impossible to complete the task of thermal design through hand calculating several thermodynamic formulas or working experience.Therefore,it is an inevitable way to control and optimize the design of heat through simulation of heat dissipation path in the light source by computer.
