摘要
为了解决由电源散热带来的照明灯体积大的问题,对一体化照明灯的电源进行了散热设计。首先分析了照明灯的结构。然后,利用经验公式分别对电源变压器和MOSFET的损耗进行理论分析与计算,并使用有限元软件完成对电源整体的温度场仿真计算。最后,以最小化照明灯体积为散热设计目标,对电源的器件布局和变压器进行重新设计,完成了电源的散热设计。结果表明,散热设计后电源的大部分器件温升均有所下降,照明灯的体积下降31.36%。所提散热设计方案有效地降低了电源的温升和照明灯的体积。
In order to solve the problem of the large size of the lighting lamp caused by the heat dissipation of the power supply,the heat dissipation of the power supply of the integrated lighting lamp is designed.First,the structure of the lamp is analyzed.Then,the losses of the power transformer and MOSFET are theoretically analyzed and calculated respectively using empirical formulas,and the simulation calculation of the temperature field of the power supply as a whole is completed using finite element software.Finally,the thermal design of the power supply is completed by redesigning the device of switching layout and transformer with the goal of minimizing the volume of the lighting lamp.The results show that the temperature rise of most compouents of the power supply has decreased after the thermal design,and the volume of the lighting lamp has decreased by 31.36%.The proposed heat dissipation design scheme effectively reduces the temperature rise of the power supply and the size of the lighting lamp.
