摘要

与传统的白炽灯和荧光灯相比,LED显示出许多优点。然而,LED本身内部产生的热量所带来的热问题,仍然是制约大功率LED稳定性、可靠性和寿命的瓶颈。为了了解LED灯的温度特性,本文利用热电偶对LED灯的温度进行测量。研究了环境温度对LED灯表面温度的影响。

Measurement for temperature on a LED lamp
LED demonstrates a number of benefits compared to traditional incandescent lamps and fluorescent lamps. However, the thermal problem that is brought by heat generated within the LED itself is still a bottleneck that limits the stability, reliability and lifetime of high power LED. In order to understand the temperature characteristics of the LED lamp, this paper utilized the thermocouples to measure the temperature on LED lamp. The effects of the ambient temperature on the surface temperature of the LED lamp were presented.
