Analysis of Thermal Characteristics of A Multichip Light-emitting Diodes Device
摘要
Abstract
A multichip LED device has complex interaction and mechanism due to thermal coupling effect. An estimation method for the thermal network model of the multichip LED device based on multichip thermal model was proposed in this paper. The predicted junction temperature in finite volume method was applied to the multichip LED device. The minimum, maximum and average de-viations of junction temperature between the proposed model and the measurement are about 0 . 8%, 6. 8% and 3. 4%, respectively. The calculated results are in good agreement with the measure-ments. These results confirm that the multichip thermal model with finite volume method can provide accurate predictions for junction temperature. The work offers a new research and development tool for practicing LED designers to accurately predict the junction temperature of LED system.关键词
