碩士 / 崑山科技大學 / 光電工程研究所 / 106 / In this paper,we proposes thermal model and heat sink design of CSP UV LED arrays for exposure light sources.The study was divided into two experiments. Experiment I: driving different current,the effect of with/without heat sink on the temperature of the light source modul,compare the results of finite element analysis and IR thermal imager. Experiment II: investigate effect of fluid factor and different heat sink design on light source module temperature through finite element analysis method to calculate and expect .
Experiment I: the driving current is 150 mA to steady state, the temperature of IR thermal imager of UV LED arrays module with/without heat sink is 91.6° C. and 44.3° C,the difference between the temperatures is 47.3 ° C ; the temperature of finite element analysis of UV LED arrays module with/without heat sink is 89.1° C. and 47.4° C,the difference between the temperatures is 41.7° C.
UV LED array module with heat sink were able effectively enhances heat dissipation through compare the results of finite element analysis and IR thermal imager.The driving current is 350 mA to steady statethe temperature of IR thermal imager and finite element analysis of UV LED arrays module with heat sink is 77° C. and 76.7° C,the difference between the temperatures is 0.3° C. providing good reliability and temperature reference condition of Experiment II.
Experiment II: flow velocity is 0.1m / s and the driving current is 350 mA to steady state,investigate effect of fluid factor and three heat sink design on light source module temperature through finite element analysis method to calculate and expect.The results, heat sink of the pins 5x5 providing good heat dissipation effect,the temperature is 68.1°C,decrease of 8.6°C..
