Experimental analysis on heat transfer performance of LED lighting radiator

Abstract

At present, LED lighting is gradually replacing the traditional lighting and becoming the fourth generation of light source. In the process of LED lighting, a large part of electric energy is converted into heat energy. If it can not dissipate heat in time, the device efficiency will be reduced or even damaged. Therefore, the heat dissipation problem of LED needs to be solved. By testing and recording the working temperature of the existing LED lighting radiator in different positions, the performance of the radiator was compared and tested. The experiment shows that the radiator works best when the light source is downward, and the temperature difference between the top and the bottom of the radiator is the smallest in this case, and the temperature at the top of the radiator is higher than that at the bottom in the working process. When the position of the LED lighting radiator changes, the heat dissipation performance of the top and bottom of the radiator changes.

Review on Thermal Analysis of LED Heat Power Dissipation and Efficiency Analysis.

“…The heat dissipation capabilities of the radiator's top and bottom vary when the LED lighting radiator's position changes. [11] 8) Tan, Lee, and Soh (2002) suggested creating an Internet-based system in their paper to enable the monitoring of significant process variables from a distributed control system (DCS). This paper suggests hardware and software design considerations that allow the user to efficiently and remotely access the process variables on the DCS.…”
