||This study aims to establish a non-destructive and non-contact system to measure the temperature of a light-emitting diode (LED) chip packaged by silicone. In the system, a detector would receive energy radiated from a LED packaged by a self-made silicone rubber after passing through the optical system. |
By measuring the radiated energy under varying parameters such as the emissivity of the chip, the temperature of the chip, and the thickness of silicone, the correlation between the measured energy and the aforementioned parameters can be constructed empirically, and based on which the chip temperature of a LED sample can thus be determined directly from a radiation measurement.
Finally, by applying the material radiation formula and the theory of energy propagation, the temperature measurement accuracy of the system would be verified through a comparison to other measurement method.
